gday guy i was just after some info on building a 350-400awkw gtr. this is a long tearmish kinda goal to acheive

keeping it at the 2.6L...many a slight bore, but not stroking it out. also using low mounted twins that are direct bolt on if possible. is this able to be acheived.

at the moment the car if off the road and is about to receive a rebuild so im hoping the parts that will be able handle that kinda power figure.

have the computer ready to go in. then there will b some money spent on other things such as new suspension set up etc. a lil maintanence to the car...that kinda stuff

is this able to be acheived??

cheers

All you need is alot of money that you'll never see again >_<

Engine will need complete rebuild if you want any sort of longevity.. forged pistons/rods, everything in the head. Fuel supply will need to be substantial, as support systems, ECU, boost controller, intake, exhaust etc etc etc $$$

Don't forget suspension, wheels/tyres and brakes!

basically you will need a built motor with cams, a decent fuel system (pump, injectors etc), ECU, upgraded AFMs, HKS 2530s and all the support gear, like oil cooler, sump baffles and oil system mods, clutch upgrade, possibly box upgrade (depending on how you drive it), little things like EBC, new cooler, good gauges etc etc. It will be a fun car though.

With an RB26 u'll be looking at $15,000+ if you want something that will last and still pull out those figures. Someone who I know has R32 gtr had a full rebuild and is a complete beast and has spent about $20k so yeh not a cheap project at all.

some of that i think depends on the use of the car

being street or track etc

YES very achievable as there a number of rb26 low mount twins running this awkw around the place.

Equipment needed

Turbos .Garret Gt2560r 707160-5 or the HKS 2530 (these are the best two choices for what you want)

Ecu. Apexi PFC (only choice in my option for street gtr)

Afms. RB20/25afms (up to 530rwhp)and Z32 afms over this level (descreen the afms is good tip)

Injectors. 700cc sards

Cams. Tomei poncam 260deg 9.15mm lift or similar HKS etc

Cam Wheels. Tomei make great units but any will do the job (yes very importane in the final tune)

Exhaust. You need dumps and full exhaust (3 1/2" is good or twin system)

Fuel system. The r32 needs a direct power supply to the fuel and most likely a pump upgrade the r33 and r34 can make the hp if the pressure is not altered on the std system.

I would note running this power for any length of time especially in a r32 you will need forged pistons and a set of arp rod bolt (atleast).

there are many other nice things you can add but i have just listed what i have found you will need

ps as for the cost of all that well it variies to much and also weather your willing to work on the car yourself

Im looking at the same amount of power in my gtr as well.Good to see someone else is in the same boat as me.

Pnblight does the Garret Gt2560r 707160-5 have the same specs and spools at the same revs as the HKS2530 ?Just wondering because I hear HKS basically sells Garret turbos but with the HKS name,so want to know if theres any difference besides the names..

Cheers.

ok the hks2530 do spare some parts with gt2560r ie turbine wheel and housing but the garret run a different compressor wheel and to try and explain the difference from what i have seen it the garret spool better and are more efficient below 1.5bar but the hks 2530 can really come in to there own after 1.5bar.

The garret gt2560r 707160-5 are the best early spool and low end hp i have seen reliative to there potient.

3500rpm ~135rwhp

4000rpm ~180rwhp

4500rpm ~240rwhp

5000rpm ~360rwhp

5500rpm ~435rwhp

7500rpm ~529.4rwhp

so as you can see the power is early and quiet linear to explain by seat of the pants ride the engine pulls from 3000rpm and the its on turbos and hailing by 4000rpm which makes it an awesome track car, very fast and user friendly.

ps hope that helps

This will give you an idea on pricing. This setup was $15000 drive in / drive out tuned.

Standard Rb26 internals.

GCG high mount manifold, GCG 35/66 SPL, Turbosmart progate 48, Sard 650cc injectors, Bosch 044 fuel pump, Apexi D-Jetro ECU, Tomei adjustable cam gears, Gates timing belt, Custom dump pipe, cooler pipes, intake pipe and filter, custom power steer resovoir, Speedflow turbo plumbing. Eboost 1. Includes labour for removal and fittment of all parts. Tune at Unigroup.

Note that no engine internals have been done, you can safely add Another 10k+ with a engine build.

      R34 Gtt Wheel Offset Advice

      By GTSBoy · Posted

      I think my main complaint with your idea is that there is a veneer of idealism spread across it. You want the simple numbers to make it easier, but all they will do is make it easier for someone to come to the wrong conclusion because the fine details will kick them in the nuts. As it is right now, the tiny bit of arithmetic is NOT the obstacle to understanding what will fit and what will not fit. The reality of trying it is what determines whether it will fit. If you had a "standard rule" that R34 GTT guards have that magic 100mm space from the hub face to whichever side you were worried about, and someone said "excellent, this wheel is only 98mm in that direction, I'll just go spend $4k on them and jam them on my sick ride".....they would just as likely find out that the "standard rule" is not true because the rear subframe is offset to one side by a fairly typical (but variable) 8mm on their car and they only have 92mm on one side and 108 on the other.

      R34 Gtt Wheel Offset Advice

      By Kinkstaah · Posted

      It still combines inches with mm, especially when you have .5 inches involved, and mm and inches that can go in either direction. This would give a clear idea on both sides of the rim, right away, with no arithmetic. Even better if somebody gives you the dimensions of the arch of multiple cars. i.e GTR may be 125mm, a A80 Supra may be 117mm, or something along those lines. Yes, you can 'know' that going from a 10in rim to a 10.5in rim with the same offset moves both sides about 6mm, but you still have to 'know' that and do the math. Often it's combined. People are going from 9.5 +27 to 10.5 +15. You may do the math to know it, but if it was going from (I had to go look it up to be sure) 241mm/2 - 27 - 93.5mm from the center line to (more math) 266/2 - 15 (118mm) from the center line. Versus 93mm vs 118mm. It's right there. If you know you have a GTT with 100mm guards you can see right away that one is close to flush and the other absolutely won't work. And when someone says "Oh the GTR is 120mm" suddenly you see that the 10.5 +15 is about perfect. (or you go and buy rims with approximately 118mm outward guard space) I think it's safe to say that given one of the most common questions in all modified cars is "How do offsets work" and "How do I know if wheels will fit on my car" that this would be much simpler... Of course, nothing will really change and nobody is going to remanufacture wheels and ditch inches and offset based on this conversation :p We'll all go "18x9+30 will line up pretty close to the guards for a R34 GTT (84mm)" but 'pretty close' is still not really defined (it is now!) and if you really care you still have go measure. Yes it depends on camber and height and dynamic movement, but so do all wheels no matter what you measure it for.

      But offsets are simple numbers. 8" wheel? Call it 200mm, near enough. +35 offset? OK, so that means the hub face is that far out from the wheel centreline. Which is 2s of mental arithmetic to get to 65mm to outer edge and 135mm to inner. It's hardly any more effort for any other wheel width or offset. As I said, I just close my eyes and can see a picture of the wheel when given the width and offset. That wouldn't help me trust that a marginal fitment would actually go in and clear everything, any more than the supposedly simple numbers you're talking about. I dunno. Maybe I just automatically do numbers.

      Ah ok interesting to know.

      Sure! But you at least have simple numbers instead of 8.5 inches +/mm, relative to your current rims you do maths with as well, and/or compare with OEM diameter, which you also need to know/research/confirm..
