R33...upgrade perfomance?

[maxkhor]

i just own a R33 GTST....the engine is original except a filter and a muffler...may i know wat should i do to the engine to get faster response? change the exhaust sys to 3in or 4 in 1st? or install FMIC 1st? or install a boost controller to upgrade boost (if yes how many should i up)? Can anyone teach me...pls...thankx...and Is hobart have any shop for R33 GTST?

What do you mean just a R33 GTST.

1. Air Intake
   
2. Exhust
   
3. FMIC
   
4. Boost Control
   

Do a search or got to www.nismo.com.au and have a look at there guide

[krawler]

PowerFC, AVCR, Adjustable exhaust cam gear, FMIC, big-arse exhaust and a good tuner.

Will get plenty of power from stock manifolds / turbos / injectors.

Budget is one thing that will influence replies...

If you're looking to keep it stockish (and run mid-low 13s):

* full 3" zorst

* bleeder @13 psi (the stock turbo will handle this fine)

* copper spark plugs gapped @ 0.8mm

* piggy back ECU (SAFC etc)

* pineapples

If you want high 12s add above with krawler and FMIC... and maybe a light flywheel and performance clutch.

PS the question "How fast do you want to go?" has the reply "How deep is your pocket?"

[aridyne]

I've run high 13's by just upgrading the intercooler and setting the boost to 14psi, everything else was stock.

I then upgraded the ECU and took an extra .8 of my ET with a mild tune and no rubber or decent clutch

i thought the stock r33 turbos were only good for around 12psi any more and they wont be lasting to long ???

[skylinegal]

Speed magazine (edition 008), has a tuning guide for RB25DET, where different tuning companies give their ideas on what they would do in terms of stage 1-3 9with prices) In regards to Leech_'s post, Advan performance centre says that they wont run any more than 10psi on the stock ECU, as they prefer to err on the side of caution.

Having said that, my gts25t was running 13.7 psi with stock turbo and ECU. That was tuned by EVO motorsport, and didnt have any probs.

Funny thing is , that each tuning company had very different ideas as to what they would do at each stage. I ended up more confused than what I was before I read the article!!!

So at that point, I decided to put my faith and trust in EVO, as they have been great so far, they know my liner very well, and also what I want, and they let me know what is good and bad.

maxkhor, welcome to the exciting and addictive ( and sometimes confusing!)world of modifications!!!!!

Cheers, skylinegal

13.7 ay hmmm i guess if its fully tuned they might be right only time will tell see you tomorrow hehe

I found there is a shop name Grifith Auto in Hobart Moonah...i saw many nissan cars in his workshop..There is a car...i think is R31...with Rb26dett....i think is around 7xxHP....is him specialise in nissan's motor? i cant find other workshop to specialise in nissan's motor....Actually...take off cat. converter is illegal in aus...wat u all guys do with the cat.converter?

Send a PM to m_rickards

he has a very powerful GTR, and is in Tazzie,

Probably best to have a chat to him as to where he takes his car.

Gotta be good with the numbers they are making and times the car is running

Yeah Griffies does the work on my car. he would be the best person to take your car to. just tell him what u want to do and he will sort it all out. he can get all parts, second hand or brand new. Griffies actually sold your car to the person you bought it off.

[aridyne]

I've run 15psi on the Stock turbo before with a stock ECU, I think changed to a Haltech ECU and well since then the turbo has run ever better and keep boost longer. However you dramatically shorten the life span of your Stock turbo if you run above 13psi according to my workshop. They have been doing all these runs for a while and found you could even run as high as 18psi on a stock RB25DET Turbo (6yrs old) for all of about 3 months before it just died.. As they said there are so many variable as no skyline comes into australia new, so how can we really tell how much abuse or use the stock turbo has already sustained, yes we can look at it, we can visual inspect and play with it, but its still been used different to every other turbo of the same model.

Shrug...

[riggaP]

I've run 13psi for almost a year without any problems. As long as you dont drive like a maniac the whole time, and only use boost when "needed" the turbo should hold.

The general rule of thumb I've found (speaking with performance shops) is dont go over 14psi if you want more than 12 months out of the stock turbo.

Remember if you're going over 10psi you will more than likely run into "over air flow protection" and the car will start to missfire around 4500-5000rpm. Piggy back ECU, proper spark plugs and gaps, tested coils, and maybe even the crank angle sensor will help this situation (in order of preference IMO).

Griffies sells imports and he imported your car and sold it to the person who use to have it

Sorry riggaP, I have had different experiences. R32 GTST with very low k's RB25DET turbo, turn boost up on Friday to 12 psi, run car on dyno on Saturday, good A/F ratios, nice FMIC etc, no pinging, result = 186 rwkw. Go to Oran Park on Sunday, third lap, bingo, turbine in the cat. I was driving.

Next car, low K's R34 GTT, turn boost up to 11 psi, good tune by CMD, HKS intercooler, Apexi fuel pump etc for 205 rwkw. Next weekend go to Wakefield Park, lap 5, bingo, turbine in the cat. I wasn't driving.

Next car, R33 GTST . Tune and run 12 psi for 2 weeks, going to SA for hols, racing Porsche on Hay Plain. After 20 k's at over 225 KPH, bingo, turbine in the cat. I was in the passenger's seat.

I have several more, but I think you get the drift. On each of these occasions the boost was "needed". If you've got it, you have to use it, otherwise why bother. :headspin:

My suggestion as always, up to 10 psi is probably OK over that and you are rolling the dice

[riggaP]

Well point taken. If your goin to the track and are on boost 90% of the time then I guess you're temping fate. However, my car rarely sees boost during the week goin from A to B because its a daily driver (and I'm a tight arse when it comes to fuel consumption ). I'm just not convinced that the odd burst on boost is goin to do all that much damage based on others I know who have had success running 10-13psi.

I can see how you could have that opinion, but the problem as I see it is you have a 14 psi car that you are afraid to use for more than "the odd burst". You might as well not bother, you can't really use it. I would much rather drive along at 10 psi and know I can safely use it any time I like, for as long as I want. I would find it frustrating, as over any length of time or distance at 14 psi it would be ultimatley slower than a car running 10 psi all the time.

But hey, whatever floats your boat
