Hi guys,

I have a 95 R33 gtst which currently has a fmic, turbosmart boost controller, bov, zorst.

as you can tell it's nothing to serious and is fairly standard. I am wanting to upgrade and was just wondering where you think I should start first? ie) turbo, ecu, injectors etc??

any advice would be appreciated,

Thanks,

Sam

Hey mate,

Good basis you have here.

First thing I would do is take the car to a mechanic and have a compression and leak down test done to assure the strengh of the engine (So it doesnt break if you make more power).

RB25's are strong and stock internals can see 250ish KW all day and it should be fine with the supporting mods.

I would get a Z32 AFM, say a Greddy GT-RS turbo, Power FC (If you can find one) 550/700cc injectors, If that boost controller is a bleed valve id get an electronic one, then a nice safe tune assuming the report came back fine from the tests. That would see an easy 250rwkw and that would be fine for you for the time being. If you want to go further, more boost ect that setup could push around 280-300 but I wouldnt.

Thanks mate,

It is a bleed valve which I know arn't the best and I will be def getting an eba. I'm getting abit of boost spike due to the bleed valve which is really annoying..as for everything that sounds good, I will get a compression test done. It's also just ticked over the 100k so need to get it a 100k service also.

yeah 250kw would be a very nice jump (untill i get bored of that and want to go faster :laugh: )

cheers for the advice mate much appreciated.

Yes getting the engine checked over for its health before doing anything is always the best move, you dont want to break the motor because you didnt replace a $150 part that would of been detected if you got the tests done.

250KW will beat every stock holden and ford on the road, it will be fun on the track as well.

Make sure you get a oil cooler if you plan on doing any track days or if you plan on giving the car a hard time. One can be had for around $300 i think. It will impove oil cooling very well.

All the mods ive listed would be doing it the "right" way. You could always get a high flow rb25 turbo, 550cc inj, z32, a wolf 3d or some cheaper ecu, and run 18psi.

Or do it right with good parts. Buy good brands stay away from cheap crap, you wont regret it. Just i hope you dont plan on selling the car soon because mods dont really hold their value.

I've had the car since Aug 08 and plan on keeping it for at least a few years.

I know what you mean about people modding their car cheaply and then end up running into all sorts of problems :laugh: and spending thousands and thousands for the same result as if it were done properly.

I'm also confident the gear box needs a reco as I'm getting a rattling sound in the gears up untill around 2000pm then it's ok. I think the bearings and or seals are shot. I have been quoted $1200 by 1 place in Syd for a reco or $2500 for a full GTR gearbox install inc. Think for now I'd go the reco as it's alot of money and I would rather spend that on other mods.

cheers mate,

I like the way you think, My car was a perfect example. I modded it with expensive parts and known brands, Greddy, HKS and Apexi. My mate who had the same car at the time done cheaper mods (Just Jap FMIC $300 ect) and i ended up with 32 more KW's @ the wheels over him and he had a newer engine with better compression.

My cylinders was 154 accross all 6. 148-155 is good

firstly how much do you wanna spend?

whats the car for?

ecu is def the next step for you, as well as some suspension work. pfc is the obvious option.

there's no point having all that power on a stock suspension setup IMHO

i'd rather have a highflow with stock injectors and afm @ 230 rwkw with a full house suspension setup than 250 with stock suspension

just food for thought :(

my journey went like this... (in rough order)

car - 33 gtst (came with with FMIC, clutch and lowered springs, short shifter)

wheels

full service and checkup

pod in box with CAI

slotted rotors DBA 296mm & good pads

PFC

splitfire coilpack (were broken so had to)

new plugs BCPR7ES gapped @ 0.8

tune

coilovers

strut brace

swaybars front and rear

castor bushes

camber bushes

pineapple bushes

hicas lock bar

cosmetic mods

audio visual mods

EBC

fuel pump

injectors

z32 afm

adj ex cam gear

new turbo

tune

prolly forgot stuff but get the general flow

the car is my daily but i'd also like to take it to the track (not turn it into a track car) and the occasional drag. So basically just a daily street car.

I don't neccesarily have a specific budget as I will obviously be out laying money over a period of time but i'm not too fussed as I have a mate in NZ thats put more than 40k into his rb30 s14 so I know it's costly lol.

first things first I need to fix the gear box then get it a major service.

since i will be doing to modding in small parts, just wondering after the service and gear box reco what I should do? I'm thinkin pod, afm, pfc?

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
