I wired up my Haltech piece of piss. The first time i did it was messy especially after i had to change igniters, but i pulled it apart and cleaned it up all good now.
Having only wired an aftermarket ECU id say that it would be alot easier than trying to wire the factory ecu into say a cressida or something like that?

Chris, I wasn't game to wire my Haltech in, at the time, either.
In hindsight, I really don't think it would be that hard ... if you're the patient, methodical, neat type.

my car has full chaser wiring loom in it and was already wired up by the dodgy bastard's brother that blew up my engine. I didn't really feel like trying to work out what he had done wrong so I gave it to the pros.
So that is Celia-Sue, Jag and Draven yet to hit the track in their jza61's. The bump spot may be getting a bit tougher after that happens!

Skip: Nah, still running the restrictive factory 'y' unit. Havn't decided on my long-term wish-list for a turbo upgrade. So, I probably won't invest in a good set of dumps unless I go with the GCG BB hi-flow ct12/GT25/T3G hybrids. Other ideas I'm kicking around (still in the 'daydream' phase ) are based around twin GT2510s or maybe GT3027 or GT3040 single. I do know I like the mid-range torque of the 1JZ and wouldn't swap it for dyno queen rwkw figures for all the world .
In truth, I don't have a dyno figure for the current set-up. At a seat-of-pants guess, it's probably around 185-190rwkw at the moment. 15 degrees timing and about 13psi boost. I think Peter will vouch that it does have some get-up-and-go to it. I hope to make it to the 'Plex in the next month to aquire some bragging numbers. 
Lately, I've been collecting bolt-on bits, that I still havn't gotten around to bolting on. Next big purchase will be wheels (Either Performance Superlite 16x7s or ROH Chicane 16x8 and 16x9s). I've also been doing some testing on CAI and airboxing options (currently, the pod filter is working as a HAI, sitting so close to the turbo-to-FMIC pipe and post thermo fan air and without additional sources of cooler air) .

I am using a wolf 3d v4. Mainly because a very knowledgeable mechanic around here is the distributor and I have seen his tuning abilities. And it was cheap as chippies

it doesnt have stock internals and didnt when it run that time.
i spoke to the owner of hardcore last friday
it has a 2jzge bottom end with no oil squirters, custom crank, pistons, rods, the head has been professionally cnc ported, valves, springs and retainers, HKS 272 cams ground to hardcore specifications. they do the same head for $4000 exchange or a bit milder head for $2800.
they said that the standard cams are a huge restriction and have done much testing to allow more air into the head to get pore power from bigger boost. the standard inlet plenum he told me becomes a restriction at 750hp at the flywheel also.
it ran that 11.4 on 20inch rims at jambo qld and run the 9.88 on its third run with the slicks and stripped out trim.
the ute that ran 11.5 ran that time making 450rwhp on nos and was driven by GORAN who owns the blue VL they built. this package has since made another 200 HP with head work.
it seems to be fact the cams are the restriction in the head of these engines and freeing them up with bigger cams will allow more boost to be run and obviously more power.
all that was from the horses mouth. i must say that he was most helpful and a nice guy over the phone.

Wow that is great info J! I was going to ring them and ask about the c4 it was using.
So they built the 1jz internals first, then ran the 11.4 and then built the 1.5jz internals and made the 1.5jz. Or was it stock bottom end 1jz with the headwork when it ran 11.4?

One car thats missing from that list is the Datsun 240Z from Zoom Magazine. It had a stock 1JZ-GTE with stock turbos and ran 12.56sec @ 112mph. That would make it 5th on the list.

Updated to include Ben Ellis's 240Z. I need more info. though. I also rang Hardcore this morning and they confirmed that the jzz30 ran 11.2@136 when it had a 1jz and a manual gearbox. That is awesome if you ask me!

its has to be a ANDRA sanctioned meeting and you must provide a timeslip and a photo of your car showing the number on the timeslip corresponds with the number on the timeslip.
is this what it takes to get your name on the list??
i spose it filters out alot of people, like me.
i have a video of my run at at a 'whoop ass wednesday' @ kwinana motorplex, ...video shows my car, my plates, my e.t but no mph (pressed stop)

I love that car

not having a shot at you chris, just the info provided to you.
365 rwkw and only 114 MPH? yeah and i see pigs fly all the time.
ask yellow rolla. MPH is an indicator of horse power. martin donnan claimed that sort of power and look at his MPH. doesnt matter if you wheel spin to half track you will still get your MPH.
amazing how the numbers tell the truth isnt it.
365rwkw is the sort of power that the celica in number 1 position is making look at his MPH or the jt autogas ute.

.J.: I was just relaying information that I was told. He said he has the dyno sheet. However, Different dynos can say different numbers. I agree though, the proof is on the strip.
Using the Hp and MPH calculation, it works out at about 325rwkw.

He said 360rwkw@27.9psi to me yesterday. It was running 22psi when he did that run. Said it was a 2.4 60ft so there is obviously quicker times to be had if the 60ft can be dropped. He said it bogged a bit and then wheelspin for quite a while.
I love that car

HYPO77 assuming 1200kg = 340rwkw
JT UTe assuming 1400kg = 335rwkw
1jz747 assuming 1550kg = 336rwkw
That is pretty bloody close
That formula is the one that all the HP calculators use on the net.

mmm, dont have a calculator with the functions, damn cheap kmart shit.
cressida weigh about 1550kg
i would say the narvara would have to be about that
and the celica would have to be around 1200kg as a celica supra weighs 1340kg and they are a lot smaller car.
i would understand from that calculation it works out power at the engine chris?

From what I have been told it is actually at the wheels rear wheel figures as there is no compensation for drivetrain losses. It is simply saying that to trap at X MPH in a vehicle of this weight, there must be this much power being put to the ground. That is how I understand it anyway.
I don’t have a fancy calc either. You do the bit in the brackets first then press =. Then remember the answer and multiply it by itself twice eg. 123/234 =.5256. So multiply by .5256 and then by .5256. Then times by weight and times .75 for kw.
Too easy

hmm an interesting topic, well done chris and J for compiling the data. i have been watching this topic for a month or so now, congratulations to everyone for getting out there and having ago.
i've learnt a lot over the past 12 months, especially about patience and racing to your budget, and also about what can and cant be done with these terrific engines.
chris, i'll speak for myself on power levels.
when i ran at QLD jamboree it was making 365 rwhp at 17psi on pump fuel. it made that power at 4XXXrpm. cant find the dyno sheet to get the exacts. i cant tell you it made 30 rwhp per PSI over 14psi, then hit the restriction wall. it is also running 96% duty cycle on the 550cc injectors i am running, so i am up for bigger injectors.
as at last weekend it made 374 rwhp at again 17psi at 4375rpm on sunoco. the fuel made big difference to torque though. it holds that power constant till redline. so there is a restriction some where in the head which from talking to HARDCORE racing components they have found the cams to be a major restriction.
i am going to try to run all sport compact events at sydney and willowbank this year, so if i there come over and introduce yourself chris, and anyone else.

That formula appears to be reasonably accurate. It calculates 209rwkw for my car, my car has been dynoed at 197rwkw. So approximately 6% difference which is good.

1jz747: Thanks for that info. mate. The more info. the better IMO. It seems that the estimate from the formula doesn't hold true with your car as it works out to 447hp. Which if you take that as flywheel HP is pretty much spot on to your dyno figure. I will go and recheck if that formula works out Flywheel or rwhp. Another thing is that your car is auto and others are manual so they should trap higher if you had the same flywheel hp. Your car seems to make a lot of power at fairly low revs which is awesome. I have seen stock turbo cars dropping off in the high rpms but I assumed that was because of the stock turbos running out of puff.
That is interesting what Hardcore have had to say about the 1jz head not flowing that well at higher boost. As a lot of people talk about the 1jz head being better than the 2jz.
If I see you at Willowbank, I will definitely come over and say hi. (as long as you aren’t too scary ). My car should be going by Jamboree this year and I haven’t heard what has happened to Drag Combat QLD since it was postponed.

J: a lowly 14.2 cause my car is such a lard tub with 4WD gearbox ratios
Chris: That formula is definitely rwhp.

oh yeah, I forgot to post that. I did a check and yes it it. But I guess it is just an estimate and I can't see it being accurate with autos and manuals.
Skip: have you been going to the gym to lose weight to run that 14? I now guarantee that you could do that before my car is finished!

Just a few facts and figures regarding the JT cars.
The navara has produced 460+rwhp on a couple of different dynos so far. All runs were done with the smaller (0.86) rear housing. It is now running a 1.06 rear housing and is making MUCH more power with minimal extra lag.
With the small housing any added boost over 22 psi didnt really add any Hp gain (we tried beleive me - 38psi on a demo run at Hunter valley street machines).
The ute hasnt had a dyno power run since the new turbo housing, but it is definately making a shiteload more grunt than ever before, we will soon find out as it is entered in the dyno comp @ powercruise this weekend !
The navara by the way came a respectable 24th outright (out of 50 entries) and 9th outright in its class (2L and over unlimmited mods) at the bullahdelah hillclimbs a fortnight ago. Not bad for a street tyred, torsion bar front / leaf spring rear agricultural vehicle.
When the ute ran at the WSID it was on second hand slicks(literally thrown away - our new ones didnt arrive in time) in a small size with at least 100 hp less than it has now. We didnt get 1 clean pass with the gearbox misbehaving - redline oil to the rescue - we wont need that excuse anymore !
It also has better gear ratios now with its new full spool and billet axles. It was really a test night to find what was neeeded to run fast, that it ran a low 11 was a pure bonus.
It will run 10's next time out.
Siko1j was dyno'd at 365 rwkw @ 27.5psi on the hills motorsport dyno. This kind of boost level was done on a dare to win a bet and has not been repeated. Keep in mind it still uses stock injectors AND computer !!
It came 4th outright and 1st in class (2L + unlimmited mods) at the hillclimb.
Since its dyno runs it too has upgraded the exhaust housing of the turbo, up to a 0.86.
400m runs last week were done at 22 psi with new turbo, on the same street tyres it ran for the hillclimb. we had severe axle tramp problems before the night was cut short due to rain. Another run or two and we might have had time to sort the tyre pressures to reduce tramp allowing a full throttle pass. As it was we wanted to baby it a litle as it still had its torsen LSD from the hillclimb installed and we didnt want to break it ! All runs were done with full tool kit, spare parts, spare tyre etc and all the usual junk that flys around Andy's car on the street.
JT Racing is also of the opinion that the cams are a major restriction, that said, serious headwork is not on the cards, at least untill the current uprepared wrecker motor lets go. The project is all about finding the limmit of the stocko 1j, and it just keeps on going !

thanks for that info. Special Ed. Can't wait to see what the Navara can do now with the extra mods! Make sure there is a video too. I have the current one and love it.
Look forward to a full throttle pass from Andy's car too. Looks like 11's are possible if all goes to plan. Which as we all know never does
Bloody hell, all this makes me want to hurry up and get my car running! Instead I have to sit here writing this bloody uni essay

My mates 1jz powered silver Cressida ran 11.59 @118mph at heathcote last meet on 12psi and a 100hp shot gas ,standard motor.Ran 12.2 with no gas and with the standard twins it ran 12.9@105mph.I think that makes it the fastest cressida in aus??

More details please! what turbo? Auto or manual? Street or slick tyres? Any pics?
Time slip would be good too. Not that I don’t believe you but I am interested to see the slip of a 1jz running NOS.
