R33 Gtst S2

Hey,

Recently had the car nistuned. Z32 Computer etc.

Car is now running 200Kw atw safely with no ping and good afrs. Required around 14+ psi on stock turbo. Yes im aware of the risks involved. In the past with a remap it ran the same with 12psi but developed some pretty bad detonation. Too much timing apparently and this had to be retarded considerably to achieve similar output without ping (is was being tuned on a hot day too, bout 30 degrees +) But the boost required to achieve 200 ATW seemed a bit excessive considering what others have posted...This engine seems to really dislike advancing the timing...

Ill be highflowing the standard turbo very soon the question is..... running the SAME pressure (say 14 to 15psi) with a highflowed turbo as opposed to the stocker, should i be expecting any sort Kw gain?? or it simply just assuring no turbine failure?

Looking for 250Kw ultimately. and i cant see how an extra 3 or 4 psi is gonna achieve that

So altering/hi-flowing the turbo and no tune?

Who knows, could be a dead motor.

As for once you have a tune - how much power is made, purely relies on the hiflow itself, what wheel combination is chosen and so on

hiflowing the turbo and having it tuned to suit.

dead motor. how so?

yes, kw gain. the highflow should be moving more air. ie. more power (with suitable tune etc etc etc)

cheers mate. simple question simple answer.

[RPR33]

yes you'll get more power at the same boost level. you should also look into a new clutch and fuel pump

i will definitely do that at the same time. Clutch was struggling on the dyno

also consider injectors. its asking a lot of the stockers at 250kw, if they get there at all.

what are the stock injectors good for usually?

Gave her a bootfull a couple of times on the way home. EBC shows peak of 14.7! dyno showed this spike, and then drop off to around 13 which it holds. Pretty much wheelspin from 5k in 1st. But 3 attempts at that and the clutch feels pretty soft...

[Dose Pipe Sutututu]

if the timing and injection values were set correctly on other load points by a good tuner and if the car was treated to a new turbo, then chances of it blowing up is quite minimal, no need to dramatise

most tuners just focus on the map trace and ignore other cells, hence sometimes you get ridiculous knock going up a hill or down shifting.

if a tuner smooths out the ignition and injection settings for everycell on the map, then there is no need to worry for such a mild motor.

For example with the stock turbo you're only hitting rows 16, and with the aftermarket one you're hitting rows 17 on the load map, and if only rows 16 and prior were tuned, then you'll have a problem.
