Hey guys

ok so gonna go ahead with the next bunch of mods... aiming for 350 - 375rwkw on E85

car is R33 GTR VSPEC

current mods are (producing 270rwkw)

- PFC

- 3" cat back

- Garrett -9s

- shitty compliance cat

- stock everything else

I need help with the following. Rather that just stating the type of part i need, it would be really helpful if people can suggest a brand and part.

I need:

- intercooler core (how thick should I go without creating any unnecessary lag)

- Injectors - 1000cc?? which brand??

- Fuel pump - I dont think an internal bosch 044 will be enough flow... will one external do the job??

- clutch - im thinking a jim berry item... do i really need a twin plate... (i am planning to take it to the strip every now n then)

- cam gears - which brand???

- boost controller - do i really need one?? or can my tuner mess around with the actuators to get the desired pressure

- exhaust system - 3.5" item

- z32 AFM - easy one

keep in mind that my budget excluding the exhaust is 4-5k... if its necessary then will fork out the extra $$ for a bigger exhaust

planning to tune it on 98 for now, but will retune for e85 when caltex do their thing

please advice

cheers

i didnt think the -9s would make that power???

stock cooler should be ok.

Jim berry Full monty clutch should be able to handle it and an occassional drag run

cam gears any brand, they all do the same thing, need to be tuned anyway.

use a decent brand EBC, profec b is affordable and very easy to setup

-9s on E85 should crack 350

i'm pretty sure i need a cooler... stock ones are good for 300ish kw from memory

yeh had profec b in old car so will prob grab one of those again (just wanted to check if they were actually needed)

made the mistake of putting a 'cheap' clutch in the old car which just fried spirited driving so I want to make sure that doesnt happen again.

thanks bud

keep em coming :)

Hey Im not sure what the -9s can flow but ive got 380rwkw on e85 with the following setup

PFC

HKS 2530s

R34 GTR intercooler (standard R32 cooler made 360rwkw)

850cc delphi injectors

2 intank walbro pumps (one 044 not enough)

no cam gears !

ive got nismo twin plate alot easier to drive with compared to single plate but will do the job fine

GREDDY PROFEC B boost controller ( u need good boost control !)

3" exhaust with ebay dumps and 2.5" downpipes

RB20/25 afms

Edited by GMASTR

interesting... 380rwkw on 3" exhaust... guess i dont really need to upgrade that

thanks for yr input man... how are your injectors holding up?? getting close to max duty cycle??

I'm going to upgrade my cooler just to be on the safe side

Yes, you do need larger. The gains to be had a quite substantial.

The E85 in his instance is somewhat masking the issue.

Cooler will also be fine mate, plenty of people here 380rwkw on the stock cooler. Some even more...

2530's will do 380-400rwkw on PULP. E85 + 2530 = 420-440rwkw territory.

But then you don't have a built motor and a filthy restrictive exhaust...

No woryz man, the exhaust has a 3" cat and two straight through mufflers and is street legal ! The only thind i needed to change were the front injector seals once, they became hard from e85 and started leaking under boost otherwise all good, my injectors are at approx 70% duty cycle, Its a good idea to change ur cooler, ive kept mine stock bcoz i wanted to achieve the most power safely using a standard motor and factory surrounding parts :(

Make my 3.5" exhaust on the HR31 is 90-91dB, I can assure you it's quieter than most 3" systems i hear around here.

Whenever i go on a cruise I'm totally stealth thats how quiet it is.

4" isn't much worse either provided you get GOOD mufflers and a big flowing CAT.

Owning a GTR isnt cheap, nor is chating 350-370rwkw... If you need a 3.5" or 4" exhaust, then pay for it :)

3.5" should do you for your setup either way.

Put ID1000's in it, mid $600's for a set.

Get cam gears definately, they are cheap !

I got a set of GATES RACING Cam Gears and timing belt in a package of the GCG AUS website for like $150, do the timing belt when you put em on !

Don't skimp on exhaust, it gets exponentially more important the more power you run.

Those turbos are too small, sure it could probably be done but do you really want to stress the your engine that hard ?

I hit 370rwkw on e85 with the following setup

2860-5's

2 x walbro intank fuel pumps

1000cc injectors

Nistune ECU

NISMO AFM's

STD Airbox

STD R34 GTR intercooler

3in exhaust

Turbosmart E-Boost street

STD cams & cam gears

I've got a Jim Berry Clutch in mine and its great!!

i dont know how your turbo's would go compared with mine?

but you dont need to change intercooler for 350rwkw, and a 3in will do 350 easily

i am finding at the moment that the STD cams, STD intercooler are holding me back from more power and maybe the exhaust too.

i am pretty happy with the setup now.

the only difference in running e85 compared with PULP is the need for a bigger fuel system.

i had 350rwkw on PULP before going to e85 and the only change i made was going from

660cc injectors to 1000cc injectors

1 x walbro fuel pump to 2 x walbro fuel pumps

STD fuel lines & rail to a second fuel line from the pump to the rail and mod the rail to suit

retune with more boost and enjoy the added midrange.

you will probably notice the biggest difference in midrange going from PULP to e85

  • 3 weeks later...

Yeh mine made 270 with stock dumps, front pipes and a compliance cat... so the consensus seems to b 2 pumps and 1000cc injecters as a minimum... the car now has bigger front pipes, hi flow cat and 3.5" catback so we'll see what happens

    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
    • I assume clearances were all a-okay?
    • Shock tower brace is in +5Kw....LOL
