Just Bought R33 Gts-t

[Quinny]

Hey all, I am relatively new to the Skyline & turbo scene (usually found playing with V8 Commodores) - but I have just bought a nice black R33 GTS-T - 1996 model. I just a couple of qustions about them:

1. How much boost does a GTS-T run standard? I don't have a boost guage so I am wondering if anyone knows off-hand.

2. How much boost is a good, safe level to increase to - maybe 12psi?

3. In the next few weeks I am looking at adding FMIC, maybe a bit more boost, and do a dyno tune. The car already has 3" turbo back exhaust & HKS pod-filter. I am hoping for around 180-200rwkw, what else do I need to do?

Thanks guys, I will post up some pics when I pick the car up next week.

Cheers.

Welcome to the Skyline world!

Standard boost is 7psi but I am told it is safe to run 12-13 with standard intercooler.

The output after the mods depends on the tuner, if the person knows what he is going then your output should be good on the dyno. I goto a guy in Granville Sydney.

I am going to get a few things done to mine soon. Turbo back exhaust(dump pipe) with High flow cat and a boost controller. I will run all this with standard air intake and intercooler. It won't cost me an arm and a leg but should get me up to 180rwkws.

You do have a boost guage - check the instrument cluster! It's in mm/Hg - not the standard psi or bar but it is an accurate boost guage.

You probably don't need anything else except for the FMIC and increase of boost to get 180rwkw.

[Quinny]

Cool, so 180-200rwkw is achievable on 12psi with exhaust, intercooler and tune (assuming the tuner knows what they are doing)? Sounds good to me.

I didn't notice the boost guage on the instrument cluster, I will have a look when I pick the car up. I have a unit converter to work out the psi figure.

Thanks guys.

10-11 you can sleep soundly at night

11-12 keeps you awake at night

12+ go to sleep knowing the fact that your turbo does not have long to live anyway

[ISC-Performance]

dont run the turbo over 1 bar of boost "14.7psi" as the wheels are ceramic and will most likely come off and fly down your exhaust as mine did...

OK, so 10 psi is a better idea, no worries. I am not as concerned about performance as I am worried about reliability. I don't want to do anything to jeopardise the reliability of the engine.

[siddr20]

Might also need cam gear (exhaust intake)..

Yup i wouldnt go above 10psi, unless i have some sort of aftermarket ecu with a good tune plus all the supporting mods.

if you want 200rwkw

you will need: apexi pfc, a decent pod filter with cai, full exhaust, ex cam gear, fmic, and i duno.. 12psi and maybe a fuel pump?

thats just stupid..

[Quinny]

Ok, so it looks like I need a little more work for 200rwkw. As I said, I am more concerned with reliablity than performance, so I don't want to go too stupid.

What sort of power would you expect from 3" exhaust, filter, FMIC, 10psi, dyno tuned on standard turbo and computer?

[R33S2]

I run 12psi but have ECU, Fmic, fuel pump and regulator plus your mods and with a good tune has 210kws, the fuel pump was my last upgrade as the standard one just didnt cut it, I haven't got after market cams and was told I wont really need them below 240kw, I know my turbo may die at this level but with careful use it has lasted 1 1/2 yrs now.

[wraith_skyline]

hey, i run mine on 10psi and have had no trouble, with 10psi, frontmount and no tuning i got 177kw at the wheels, so there is a good indication for ya

That is what I like to hear. I want to avoid spending too much money on the car, I have spent way too much money on cars in the last couple of years. I want to try to get the best gains I can with the basic bolt-on mods. I don't want to go to the trouble of changing the turbo, internals, upgrade the fuel system etc, I just want the best gains I can get for a basically "standard" car.

[Quinny]

Would I be better off spending my money on a good intercooler or a Power FC computer and dyno tune? Which would give better gains for the money for a basically stock engine (10psi, exhaust & filter)?

I will be getting both at some stage, but which would be better to get first?

FMIC by itself doesn't do anything for extra performance. It allows you to run higher boost pressure. It is also a safety-net sort of part as FMIC will make your car run better on hot days.

PowerFC will let you control air/fuel/ignition etc.

Most people will get the FMIC first but if you don't want to increase boost pressure you may want to get the PowerFC first - this will allow you to do changes like run better AFRs which will make your car perform better as well as conserve fuel in the top end.

[Quinny]

Thanks mate, I might let a dyno run decide what to do next, if everything looks ok, then I think I will bump the boost up to 10psi, and add the FMIC, then get the computer a little later. If the tune looks out when the dyno run is done, I will get the computer and re-tune. Thanks guys. Sorry for all the questions, I am new at this....

I have just started putting a new website together still in progress but I have uploaded a R33 tuning guide which will help you and others. Read this guide and let me know what you think.R33 Tuning Guide

Thanks Munna1, that is very helpful.

I noticed tonight that my car has a flat-spot between about 3000-4000 rpm. What would cause this? As far as I am aware the car is running factory boost, but I don't know for sure...
