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.

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

my 2c

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.

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?

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...

thats just stupid..

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?

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.

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.

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.

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

Cheers

PS: Please excuse the spelling :P

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
