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?

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
