Hi people,i am totally new to drag racing but this import street drag challenge is cool.street tyres [read treaded slicks] pump fuel [prolly laced with hi octane additives] not sure of other restrictions.It has to be imported presumably.original engine? suppose so.
So,have a spare auto 1j.What is the lightest car I could put it in to be eligible for this comp.Need a 11 something to be competitive.
smart guys with slide rules please inform-Hi 11 sec quarter with a 1j auto.Your best set up on a beer budget DIY hopefully light weight import Toyota? Is it possible without a squillion?
All input welcome.Cheers.Pete.

does it need to be street registered?
from what i recall the lightest celica u can put a 1JZ into is a RA40.

For ease of installation, relatively light weight and low cost an early model Corona MKII would be your best bet I reckon (6cyl to start with so a good sized engine bay). With a shft kitted auto, standard turbos, aftermarket injection, some good fuel and a decent tune you'd slot in easily.
Alternatively, one of the later model celicas (the hatchack type) may have the advantage of decent aerodynamics helping in the top end. Have a look at the cars at the top of the list-they all have good shapes. At 200kph+ the wind noise in my crown is deafening, and it's really hitting an aerodynamic brick wall.
An early model celica will probably more difficult to get hold of in good nick (unless you fork out 2-3 times as much as for a mint corona)-and I'd advise that for ease of building yuo start with an unmodified, mint condition car-it makes things far simpler than if you have to fix it up as well (ie-rust, dents, non-standard wiring to decipher etc).
Be aware that with my 11.37 on the street tyres I'm now back in 8th, and that I suspect that soon that time won't even keep me on the list. (although next time out I'm aiming for 10.8 or faster)
Take it easy

you'll also have to factor in a suitable dif and brakes for the RA40 - neither would be suitable for 1Jness
you could also try corona? XT130 or similar see Chris Davey at al regarding this as it's a harder conversion, but possibly lighter car... plus you could be starting off with better brakes this way.

yeah I was going to have a crack at that list when my car hits the track. I don't know how much Celicas weigh but my Rona weighs 1050kg stock. I haven't had a chance to weigh in since conversion though. The engine and diff are heavier but the car is totally stripped out so...?
BTW Charles there is NO WAY I would be using the stock rona brakes with that sort of power! I have new HQ holden brakes on the front with better pads and pajero brakes on the rear.
I still think you would need some decent engine upgrades to run an 11 as that is pretty damn fast. I was hoping to run a mid to high 12 when I was on stock twins with dump pipes etc.

RA60 will be a good bet then
live axle rear end (0% IRS squat) and very good drag co-efficient around 0.35 (if i recall) for the MA61 which has a similar shape to RA60 (maybe stick RA65 bumper and headlights on it too).
also kingswood brake upgrade == teh p00 by todays standards

I wouldnt do it to anything like an MX23 or RA2* - too rare to destroy makes it pricey to buy.
I think Rob's RA60 idea or even an RT142 would do ok.
RT142 has F series IRS too.
NB: these are all considering your 1JZ-GTE requirement.
Otherwise i'd just go the lightest thing a 1UZ-FTE will fit into.

I'd say if you want to get into the HPI top street tyre lists that you should forget about the 1J, at least if you want to get a decent position.
Why? Well the class you'll be in is over 2400 RWD which means you'll be competeing against engines of any capacity bigger than yours basically.
If I were trying to get a Toyota onto a decent position on those lists I'd build a 3S stroker. Big cams huge turbo plenty of fuel supply and good management will make the power needed. Then put it into either an AW11 or a KE25. The AW11 has a traction advantage but the KE25 has the weight advantage.
This way you're using a light car with an engine in the upper reachs of it's capacity class rather than the smallest engine possible.

Compared to the Jap street drag times (genuine STREET cars driven on the street, not those Veilside fuckers...) our HPI records are ordinary.
Take this example: HPI Supra/ Soarer special edition.
JZA70 Supra- HKS GT3540, Power FC, all other needed mods to make 2 bar out of the turbo, stock internals and Nitto tyres. 1/4 mile time: 10.6 sec.
With this setup, you'd make 2nd place on our HPI street records.
DON'T BAG THE 1JZ, BITCH!
Hey Joshstix,
You needn't go to that much trouble, a AW11 is coming second. It has a GT30 turbo, some other mods to make it handle the power and has an ET of 10.66 sec. No where near as extreme as what you describe above.

Sure in theory that works but you see a lot of cars getting around with the same mods you've listed that run nothing like those times.

They don't have the same setup. Their driving skills must also be lacking, to run a 10.6 in a 'heavy' JZA70, the driver (Kun) must be a freak.

Am I to assume the aformentioned supra runs a 1J?
Regardless, The 1JZ is a great engine, but it's at the bottom of it's class. You're just putting yourself at a disadvantage for no good reason. Anything you can fit a 1JZ in you can fit a 1UZ in. And if you're going to add a dirty great turbo and aftermarket management to the 1jz, have a look at the RA28 in perth, it ran a 9.5 (Tubbed rear) with a 1UZ, 2 turbo's, extra fuel rail and management about 500KW or something I think...
Tim.
eitd: shit, I just realised it's a JZA70, not 80. It's 2:30, that's my excuse
