Boosting A Stock R33

[bustafat]

Guys

just a quick one

i got an R33 gtst, stock everything except i got a full exaust system turbo back

just put in a boost controller and was wondering what people have boosted their car to

is 10psi excessive?

cheers

You might run into some boost cut / rich and retard problems with turbo back and everything else stock running 10psi.

[sam5709]

if you want your stock turbo to last you then 10 psi is all good, more than that starts to get unsafe, although i have heard of peoples stock turbo lasting ages on 14 psi

but yeah, 10 psi is safe, i wouldnt go more than that

I ran 10psi on mine it was stock bar a turbo back and pod filter had no dramas whatsoever.

I plan running mine dual stage, 7psi for low everyday use and 12 psi for drags and when I want performance. What do u all reckon? Stock everything execpt turbo back exhaust and soon to have fmic

[DivHunter]

You'll at least want to have the AFRs checked.

What about with a stock exhaust BUT with a R34 SMIC, what boost?

[Zas)-(]

12 psi is a good one to have with dual stage

i use it and dont see the ecu going rich and retarded like it did on 14psi !!!

so 12's orite, if you really want perfection checks the afrs, tune, safc, etc but really just for drags yeah man 12's just fine if u running 7 psi everyday

p.s any more tho asking for trouble without a bigger front mount and basic mods

7psi....as I have been kindly directed by members of this forum

Its no good for your turbo to be trying to blow through a tiny pipe that has a few 90 degree bends.

What happens when you blow through a small straw a lot harder than normal??........ Your face goes red and heats up.......so does your turbo

nice, nice

[Nismo_God]

probably a noob question but can u play with a stock ecu, as in make adjustments to adapt with the change in boost? can ratios be tinkered with?

[mad082]

but when i put the R34 SMIC it went to 8psi automatically, so surely 1psi more cant hurt it can it?...Im no expert tho, so any thoughts would be appreciated.

Are you sure your boost went up when you put the smic on? or was it the BC that you put on.

I did this same mod to my car, and boost didn't go up.

I'm no expert either, but it doesn't take an expert to tell you that your performance gains will be minimal until you do your exhaust.

Sure you can bump the boost up a bit, you'll definitely feel it pick up better down low, but overall performance won't increase by much, along with you putting unnecessary strain on the turbo.

yea was before i got boost control & still had std dual stage bleed 5/7psi...as soon as i out on SMIC i noticed it hitting 5psi alot earlier & also went to just under 8psi instead of 7psi

yea down low is awesome now & i agree without an exhaust not much gain in power is to be had especially in higher revs but just want to know whats a safe boost til i get an exhaust and power fc later on

As I said when I had a full exhaust and pod filter 10psi was fine had no dramas with it whatsoever. I wouldnt go any higher than that on the stock cooler though as there not very good at scrubbing the heat especially as we are getting into the hotter period of the year. I would leave your boost as is till you get an exhaust.
