278 kw @ wheels standard turbos and internals R34 GTR

[markr34gtr]

nice results snowman.

next tuesday i am getting my r34 gtr tuned so i will post my results...

cheers...

As an update - Ive just come back from racepace where my car produced 255rwkw @ 15psi boost. We didnt want to increase the boost right now as the car is heading out to Phillip Island next weekend and 15psi is safe for the stock turbo's there.

But there was a power increase of 20rwkw when we upped the boost from 14psi to 15psi so I could see a figure very similar to that produced by jezzrrr @ 1.2bar.  

So I got a nice 77rwkw gain by changing over to the power fc, adjusting the cam gears and a slight increase in boost. Very happy with that. And the power delivery is so smooth now.

There was a second R34 going on later in the day with new Garret 2530's installed. Will find out what that made and post it as well. Will be good to get a comparison basically straight after mine to see how much difference this turbo upgrade makes considering conditions will be the same.

[markr34gtr]

mine has hks 2530's with dumps, 700cc sard inj, nismo fuel pump,hks intercooler,power fc,

z32 afms..blitz id boost controller.

i am hoping for 300 plus rwks.... the more rwks the better...

might stick to about 1.4 bar boost should be safe for stock bottom end....

cheers..

LOL - your car has taken longer than mine. And it was still in bits this morning! My car was meant to be there LAST tuesday but only made it today. So good luck with getting it there on Friday!

Dyno took a couple of hours I guess. Didnt pay 100% attention to exactly how long as we were there for ages (I had to run Gerald around to try and find a M7 bolt) plus the cams hadn't been adjusted or the power fc fitted before we got there. And Im not sure as to cost considering I've also had a new clutch, plugs, oil cooler and pads as well as the power fc and cams fitted this last fortnight - and Im not sure of the exact individual breakdown of costs involved. I just know Im broke now.

How many pieces was it in?

My car should only have the cooler piping left to do, unless gerald is telling me stories.

Na mate it was ok - infact it was the most complete Ive seen it in the last month. BUT as you surely must know by now they aren't the best at meeting completion dates. I was due to get my car back last tuesday, then the dyno was postponed to Sat... then to yesterday when it was meant to be finished. Well the dyno was done..... but the oil cooler hadn't quite managed to get fitted. Im told it will be finished today. Im not holding my breath. (Mind you they know Im not in a hurry as its not my daily driver or anything)

They are pretty stoked with the job done on your car though so I think they are as keen to get it finished as you are and see the results. So you might be lucky!

Sorry to hijack this thread as i find it most interesting.

I was just wondering if any of you guys have been to Maztech?

Just wanting to know if they are any good?

My car was worked on there and i have a heap of receipts for there.

Trouble is when i call up to get dyno sheets they never send them, just wanna know what power my car was making b4 i had troubles

Yes believe me i know this well. I have known them for 3 years and yes i know this wellllllllllllllllllllll

INASNT,

nice car, but please mate... what is with those blue interior panels??

greeeeaaaat oriental confuscious say "rice boy, begin with painting interior panels, then gt wing, then big blow off valve, then neon tubing interior, then stickers on car panel.... once rice becomes master he moves on to bonzai"

I started a thread about my interior panels a few years ago. The gist of it was that i had a hankering for sum fried rice, but was to lazy to go get some, so i grabbed a can of paint and made my own rice

Hi all,

just a side issue for the R34 boys. Do any of you have a list of the interchangeable items engine wise between R32 / 33 / 34 ??

Ned as far as I know there isnt much that isnt interchangable, the engine is virtually identical from 32 - 34.

Thanks Jezza,

I was thinking about exhausts, front pipes, dumps, they are often marked as fitting a specific model, but would an R32 catback fit an R34 for example?

i think the front pipes are the same but cat back wont fit......

hope this helps...

Not every one wants to race their cars...

I can agree with that, so what if the car has never seen the drag strip, none of my cars have. :Oops: Hats off to the ppl that muster good times out of a car, but also hats off to the ppl that can enjoy their cars without needing to race them.

It would seem that R34 GTRs throw out slightly higher numbers with the usual bolt ons then earlier models. Whats ppls thoughts why... purely because its a fresher engine, more effecient drivetrain, turbo technology, engine spec- are heads/cams/compression all identical ????

[TTT]

are the diff and gearbox ratios identical from R32 - R34 gtrs?

If not, could this be the cause of the higher rwkw figures on teh R34's?

I'm not doubting the cars ability, just want to know how..

Just like the bug eyed WRX is supposed to have 160kw at the engine and when people dyno a my99 (older shape) which also has 160kw at the engine, the bug eyed rex produces higher ATW numbers than the my99.

And it is mainly due to the fact that the gearbox/diff ratio's are different to the older shape..

Can anyone confirm if this is true in the GTR series?

[Roy]

Well obviously R32/33 vs R34 are 5 spd v 6 spd, and i recall reading the R34s have a different rear diff (from Motor mag...so???) so the drivetrain loss could very well tell part of the story.

Also i notice jezzrrr you are using std ECU and AFMs. What was the fuelling/ignition like, must be reasonable to be getting those numbers. Would some 80mm AFMs and a tune liberate a few extra kws???

Alot of high hp cars seem to come out of perth but without the 1/4 times to match them!!

Do u have a printout of your dyno sheet to post?

yep it's the opposite in perth. I look forward to building a 2rwkw drag car in the new year.
