selecting a chassis for a 1jzgte track car

Heya peoples I am building a dedicated track car for a new australian racing forumla and need a bit of help.
I am aiming for a track only car with 220rwkw with a total weight of 1100kgs.
I want to build it around a 1jzgte and am aiming to use the standard turbos, injectors and ecu. but i will be using 600 x 300 x 76 intercooler, bigger fuel pump and 3.5" exhaust with custom dumps.
First of all with out any major welding of firewalls what are the options for a small cheap chassis. keep in mind this car will not see road use just track so i am not too concearned about wether i will be able to get it registered. or what the shape/look of the car will be. so everything will be coming out of the car that dosent have to be there, interior will just be a steering wheel, drivers seat and thats about it. I will be doing all the fabrication my self
what i need to know is:
1. what will a 1jzgte fit into to that will keep the weight below 1100kgs? I would prefer a 70's model eg, ke10,15/ta22,23. I would prefer not to go the ae86 route... any other car suggestions?
2. What options are there for a manual gearbox for a 1jz?
3. Is 220rwkw realistic with the 1jz without changing the turbos or engine management?
4. Can the standard computer be remapped like a nissan computer?
Its been a while since i have worked on toyotas i have been working on rb20s and sr20s for the last 2 years but you just cant beet the performance to $$$$ ratio of a 1jz and not to mention the reliability. so i am going toyota this time.

1jz with custom dumps and a front mount will make 220rwkw easily - you'll more than likely get a few more. I've got 210, and that's with my turbos choking top end because of the standard dumps.
main problem you'll have with the ra23/ta22 chassis are that it'll be a really tight fit, even with a slim line thermo and 2core alloy radiator, and because it's so tight you're going to end up with a lot of wight over the front wheels.
I'm not even sure if anyone's tried to fit one to a KE10, but I can only think the above problems will be even more prnounced. and RA65 would probably do it for you, with the advantage of IRS, ad it would easily be below 1100kgs.
for a track car, even an ma61 would be below 1100kgs once you stip the interior. (mine is about 1350 wet weight, fully loaded with driver)

1GG fits into KE30 just.. KE10.. take off maybe 20-30cm out of engine bay length = nochance.. heck the 4K with radiator and fan barely fits in there
now if you were to mount the 1J halfway into the cabin you'd be onto something . KE1x start at 720 bare, but track is small etc...
what formula are you building for? any online links?

Corona plenty of thai's throw 1jzgte's in em.
I reckon an Ra65 would be sweet, or an stripped ma61.

Least you'd have a good looking car for a track car then
Plenty of room, too.

and as for gbox, you've got a few options.
there's the "agricultural" R154 (so called becuase it shifts like a tractor) - this will bolt straight up.
then there's the V160, getrag 6-speed. fantastic box, will never die, but pretty heavy and very expensive.
Most common option is to get the bellhousing off a 2jz-ge and bolt up a w58. it's relatively cheap, fairly light (compared to the previous 2) and is showing no signs of exploding behind my engine (although norbie has managed to kill a few, he has a lot more torque, and drives as though he is trying to kill the gbox)

I think you will be pushing to get it to 1100kg if you are including driver. My car is a totally stripped xt130 corona which supposably weighs between 1000 and 1060kg standard and it weighs 1280kg with me (95kg) in it. You could squeeze it into a smaller car but then you are going to stuff up the weight distribution and I think the lower weight wouldn’t be of much help. Why not a 1g with single turbo into something smaller? They can make 220rwkw pretty easily and they are a bit shorter and lighter than a 1jz.

hahaha my fact post has to be one of the longest in the history of toymods.
I'd put it in an XA6X celica they weigh fuck all and i belive the 1jzgte will fit in it ok.
best of luck with it i can't wait to see it when ur finished

The racing class is still in the developmental stages and there is nothing on it floating around the net yet.
I am stuck on the 1jz as i want the engine as standard as possible. so that puts the 1gg out of the question.
How much does an ra65 weigh?
also did they all come with IRS?
Was the model with the coupe ugly ass back a ra65 as well as the hatch and did this weigh less?
Thanks for the many helpful replies guys

fwiw: a rally-prep'd MA61 (with a 5ME built up to a 6MGE) is nearly up to 1200Kg (wet but no humans).
that's with a decent roll cage, selective re-enforcing of spots on the chassis and commondoor brakes/coil-overs on the front.
if you really need 6 cyl then ra60/65; sa63; ra40; AE86 are most likely to get you close to 1100kg. Anything else will require firewall surgery.
but if you want IRS along with that package then you have to restrict yourself and possibly consider heavier bodies like ma61 or mz10
fwiw: wilbo & i are building a track car based on an MZ10. The weight target isn't that strict for us.
cheers,
Charles.

in terms of weight my rona only weighs 1080kg (live rear), and you could get an avante with irs that accepts f series lsd's with 4 wheel discs.

that's 'cause you're a big fatty chris
my anorexic girl's body will cut that weight down by 30kgs right there.
assuming 1350 wet weight for my car, by removing rear seats, passenger seat, saving 5kgs on a shell mounted race seat, no spare tyre, no trim, carpets, rooflining, no heater or aircon crap, remove most of the dash, I reckon cutting off 200kg wouldn't be too much of a chore.
that's without looking at any money spent on weight saving, or even getting serious (power windows replaced with manual lexane, ditch central locking, ditch power steering, etc)
I should also add that my 1350 includes big brakes up front, heavy thermos and all the piping you'll need.

and depending on budget, a 3s style celica like Shane's would be lighter ad still put out bags of power. but you're looking at thousands more for that.

I'd say RA40, not the hatch though.
To the question you haven't had any input on though, no the toyota computers can't be programmed like the Nissan ones.

Probably about 550kg to build a race one with 1JZ. You won't have to worry about panel damage then cause the field can be kept as far as you like behind you.

and a 3.5" exhaust for that little power is just extra weight. 3" is more than enough for your needs.

Does it have to be a Toyota shell? Cause they DO fit in S13 Silvias, which are pretty light, especially stripped.
Plus then you've got the luxury of easily available break / suspension upgrades.

OI! My mum says I am big boned
On topic: I still think it is going to be difficult to get to that weight level if that is including driver. That means that the car would have to be just over 1000kg wet. The engine and box (if you use r154 it would be heavier than a340e I use) are very heavy so the base weight of the car would have to be around 900kg or less I would think. You also have to factor in the weight of a diff that can handle that power. I don't think it would make the weight break but I would be going with an s13 I think, mainly because of parts availabilty.

I'm told the RA65 weighs just over 1000kg but don't quote me on that.
All but the RA60 came with IRS
The Ugly ass boot that looks like a fat person sat on it weighs a bit more than the lift back I THINK
I think so because my mate has one and his can't break traction or get anywhere near mine

The 225rwkw is there at 15psi provided your exhaust flows VERY well.If you are required to have cat converter ensure its up to the task or use 2 to ensure no flo block.hollow ones are good but I like breathing so dont do that.

ok, a bit more on the class.
it has been labled "compact import improved production"
and what i have on it sofar is.
no more than 1KW per 5KG
vehicle weight no less than 700kg
vehicle weight no more than 1150kg
engine can be of capacity between 1000 - 2530cc (keeps out rb260
engine must use original induction accessories and management
brakes and driveline must be the same manufacturer as the chassis
thats all i mnkw so far. will have a chat to my dad later to find out a bit more.
so it looks like the ra65 is the go.
I have a bit more weight than i thought. The reason i chose the 1jz is its the easiest engine to get 220rwkw out of without induction changes.
so the ra65 will fit the bill perfectly.
guess i better start hunting for some coilovers and brakes.
the 1jz weighs 200kgs complete
from my research the ra65 rolling shell with suspension, brakes, no interior but a 1/2 cage and drivers seat will weigh between 780 and 830.
and i am guessing the gearbox will weigh 50 - 60 kgs
so we are looking at 1090 dry! looks good sofar!!!
the weight limit is without driver

RA65 is a good option. The brakes and suspension are very similar to the MA61 so you'll find plenty of info here about upgrades. Another good thing about the RA65 is it has an F series diff which will actually survive behind a 1JZ. Just grab an LSD centre out of an MA61 (or an aftermarket one) and you're set!

You better find out if a 6 can go where a 4 used to reside. Most of these classes tend not to allow such a change. Also see if turbo motors have a capacity multplier such that the largest capacity turbo motor would aactually be 2530 divided by the capacity multiplier. Some of the sports car classes have such stipulations. I would be getting the class regs and having a really good look at them.
Best bet will then be a an MX32. They are actually very light - I think they are lighter than all suggestions thus far and have enough engine bay to not necessitate a rack and pinion conversion (which I'm sure will also be unallowable).
Personally, I would be looking at 240Z - RB25DET combo as class leading. Another option would be 13BT - RX3 (if the rotor actually squeezes in, but I think it may just pip you - they also are rated as 2.6 litre - you should seek clarification).
If you are really only allowed NA motors, I'd be looking at SR16DE Neo/SR20DE into Datto 1200/120Y, 20V into KE20 or BEAMS 3SGE TA23.

yes i have checked about the 6cyl being allowed and thats ok.
the 2.5lt capacity is even allowed turbocharged as long as ite intake system is standard. this means turbos, fuel, and original maf or afm. I have asked about the intercooler and aftermarket intercoolers are allowed as long as they were available at the time of engine and chassis manufacture. so i will be looking for a r32 gtr intercooler aswell .
Hey norbie, whats the weight balance like in your car? have you ever taken it to the track? or even drifted it? what mods were required to fit the 1jz?
what crossmember did u use ect? did you need a special sump?
are coilovers easily available ofr the ra65?
I just ordered me a 1JZGTE halfcut from a chaser. its auto but I already have a manual computer on the way

You'll need a front sump, which fortunately the chaser has
if brakes have to be same maufacturer, I assume you're going to be looking for some mk4 supra brakes, or something similar?

i think you should be looking at less power
i think u will find 220kw in a 1100kg car to be much more than u need, id concentrate on getting the handling & brakes sorted before i worried about power
anyone can get more power, but to make a car handle and stop well takes much more effort/finesse

the class does not require restrictors infront of the turbo
I really dont know anything more about the class yet. I dont even know who is organising it. I will have to ask my dad all about it when i see him is a couple of weeks. he overseas ATM.
from what i can see its a derivative on "improved production"
differences being there are weight limits and they are allowing imports to compete aswell. so it will be a really varied feild.
I wanted to go the AW11 with a 4agte but they wont allow it.
and i am trying to keep the budget below $9000. so it rules out a properly set up 3sgte later model mr2.
and whoever said about the rotaries was correct. they are listed as being a 2.6 litre! and i dont want a lawnmower anyway they are fun but not my thing...
I love the power delivery of an inline six. and I have already ordered the 1jzgte so I am stuck with it!!!
so does anyone on these forums have a 1jz in a ra65? I would be very interested in having a look/ride on one.

As mentioned I have a 2JZ-GTE and I put it in an MA61 Supra so my experience probably isn't much help to you. If you're concerned about weight balance you should have a good think about using an MA61 chassis; it's actually built around a long heavy inline six so the balance will be much better than shoehorning a 1JZ into the shorter RA65. Yes there will be a weight penalty using the MA61 chassis, but after the engine conversion is done I reckon there will be stuff-all difference and the better balance will probably make it worthwhile. You also get to run bigger tyres in the standard guards, which is a major bonus if you're restricted in that area too.

Cause he's already got the 1J on the way? And I'd hazzard a guess at saying that a stock 1j will easily out perform a stock 12a.

I am not sure i follow you.
The 1jz is capable of putting out 220rwkw correct?
the vehicle weight i am aiming at is 1100kgs
devide 1100 by 220 and you get 5.
so that means 5kg per KW. but if my conversions are not right please let me know
I am not taking a stab, just dont not sure what u mean

he means flywheel power vs rear wheel power
flywheel output will be higher than power at the wheels, it depends on what the requirement is on what you need to match
and i was talking about a 12a for someone else, i can see he has purchased a 1j already

thats the one.. most classes of racing where power is restricted are classified by flywheel kw, not rwkw... you should check carefully or you might have a heavy motor detuned to stay within limits.....
or just rev limit it to 4000rpm
i also think that where you have power limits, an SC comes into it's own.. less rpm = less power, but you can have shitpiles of torque everywhere.. none of this lag crap

also consider your weight balance when putting a 1j in something
u want to keep it as close as u can to 50/50, but with a 200kg donk up front, consider how you will balance that out at the rear

Best bet will then be a an MX32. They are actually very light - I think they are lighter than all suggestions thus far and have enough engine bay to not necessitate a rack and pinion conversion (which I'm sure will also be unallowable).
|
Turbos + Steering box = prbly not going to fit without custom rack and pinion setup....
MX62 would be interesting, but not really that light and no IRS such as the RA65, MZ10 and MA61 (stupid E series, I guess you could put a MS112 etc F series in, but weight then becomes an issue..)...also have a steering box (prbly foul the turbos) and a stupidly large number of turns lock to lock!
If the class allows imports this could be a good class for me and thechuckster to look into

IPR cars are allowed on the basis of homologation, as is it be have been homologated as a touring car, OR, it must be proven to meet the requirements of being a touring car. now i dont know what those requirements are but various cars have been allowed into IPR due to being proved to meet the critea (ie. 1st gen Rx7's which were homologated as a "sports car")
it is just a very long drawn out process for it to happen

Hey champ, I am not sure as to whether you have considered it this way or not?
1kw/5kg right!
Vehicle can weigh no less than 700kg and no more than 1150kg.
In either event any engine or any car you decide on cannot exceed a power to weight ratio of 1kw/5kgs!
So if you have a 1150kg vehicle with 230kw max (according to your equation, you will be allowed 230kw)
What would be the difference in having a:
700kg car with 140kw??????
Just a thought.
May widen your choices to a car you actually like and an engine you like which in turn may end up easier to fit in!

Yeah a 700kg 140kw car , would be easier on brakes , tyres , and handle better . So why would anyone bother with any cars above 1000kg ?, most two litre sport sedans weigh between 700-1000kg . Ofcourse there rules will allow more modifications than this "compact import improved production" .
The toyota six cylinder cars running in the sport sedan , 2litre here in Victoria are that yellow Rx7 series 4 , and open class a 1g in a MZ soarer ? that Avo sponsored i think . Unfortunately both are way behind in those classes , maybe its not the motor . But i dont see that there has every been a successful straight six cylinder in a class which allows engine modifications , V6 yes lots of victorys , so this new class might close this gap with the restrictions on the engines . But everyone cheats anyway
With the classification of classing a car a SPORTS CAR , in the case which has been progressing for a long time is a Alfa GTV which is called a 2+2 coupe in lots of countrys racing . But here is classed as a sport car due to the size of the rear seat , which is somehow smaller than the RX7 series one . So you might also want to check on if you use a coupe that it doesn't get classes the same , Lucky AE86's have large rear seats .
My money would be on the cars which GT has already list " SR16DE Neo/SR20DE into Datto 1200/120Y, 20V into KE20 " but if they class the rules as per that other improved limited class some front wheel drive cars might be more a pick due to the large amounts of engines available . Maybe if they do a original manufacturer of vehicle , must have the same make of motor etc i would be going out for a Mk2 golf with R32 running gear .
Whats the tyre ruling going to be to , this alway's disadvantages larger heavier cars made to run large profile skinny tyres ?
