  • Share this topic

675 posts in this topic

this is of great interest to me currently as im yet to choose turbo(s) for my new build.

please no chatter or conversations as to make the thread easier to wade through if it gets as big as the rb25 thread!

all relevant engine mods would be great too.

cheers

this one came with the car, unsure of boost but i think its 18psi. Looks like full boost by ~4750rpm.

HKS 2530's and split dumps

Z32 AFMs

Power FC

sard 700cc injectors

full 3.5inch exaust, cat pipe

standard motor and cams

usual support mods.

gt2530a.jpg

was retuned at racepace 330kw at the wheels (rear?) at 18psi. Unfortunately that dyno sheet is unavailable.

well i can only give you a baseline atm.

this is:

R32 GTR

stock turbos

stock dumps, fronts, stock IC

3 inch exhaust

cam gears (on stock cams)

14psi boost using trust profec B spec II

Power FC (tuned by Hitman)

Apexi power intake kit

it made 253 rwkw, but i had them fiddle a little bit more for a slightly fatter midrange, ending up with 247. I thought that was pretty good going for just cat back exhaust, pods, 1 bar and a PFC + cam gears. But it's no where near enough these days :D

1997 R33 GTR - VSpec

K&N filters

Power FC with std AFM - 15 psi

HKS Hi Power Cat back exhaust

De-CAT

Apexi Front pipes

Twin plate clutch

Everything else (power related) standard

Dyno_150605.pdf

Not sure how to post pictures, if u cant c it then let me know how to post.

This set-up was OK for a month or 2 then AFR increased, Power dropped to 340HP and the following were installed :-

Nismo fuel pump

Nismo fuel pressure regulator

Trust fuel rail

SARD 700cc injectors

Now all running fine and back to 360HP.

Why do some dyno runs have KMH on the X-Axis? I find it of very little use, difficult to tell where power is being delivered. Ask your tuners for RPM...

will get the dyno graphs scanned so that I can post here.

stock everything bar M's pods and large front pipes + 3in highflow cat and 3in exhaust = 230rwkw @ 10psi

same as above parts, but with HKS intank pump, GT2530's Xforce dumps = 275rwkw @ 17psi - not DET, safe AFR's (it still wanted more boost!)

yet to fit PFC, Sard 700 inj's, HKS cam gears, bigger AFM's and 3.5in exhaust. shooting for ~ 320rwkw.

oh - all done on a non rebuilt '89 GTR that I have had for near 2 years.

292kw at 4 wheels @ only 16 psi on BP Ultimate/injectors at 70% duty cycle

* Should go 340kw+ at 4 wheels @ 22psi

*OK its not going to make 450rwkw+ like some bigger combo's but the great thing with this combo is its amazing boost properties and drivability-only marginally more lag than stock turbo's

*will attach dyno sheets soon.
