Hi.

I have an S1 stagea and just fitted the turbotech boost controller to try and get some more boost out of it. However it seems the more boost i put into it the worse it drives, gauge is showing 10-12psi but the car doesnt seem to move very well, then after about 4500-5000rpm the gauge tapers down to about 7/8psi but the car pulls harder, as in its still doing the factory dual boost settings from what i can feel, but the gauge is showing otherwise ..

Is an ecu and tune nessasary for this to work better?

Cheers, grant.

Hahahahaha :) yeh the guys on here are ruthless. Don't know everything about everything and you're burnt! :thumbsup:

I recently installed a turbotech on a stock ECU/turbo setup, just like the guy who posted this thread. After 11psi the ECU protects the engine by running rich (& retard) so you don't pump too much compressed air into the combustion chamber without enough fuel (as the factory air/fuel ratios haven't been tuned on the factory ECU above this boost setting). If the mixture runs lean you can bust the motor, i.e. warping conrods or the crank, that's why it does this.

For example my R33 'hesitates' when i mash the throttle at 12+psi because it runs rich to keep the engine safe. This is what happens to you by the look of it.

My advice is keep the boost set to 10psi, 11psi MAX. It is better for the stock turbo anyway. If you get the ECU remapped you can take it up to 1bar if the tuner is comfortable with it.

Have fun :wave:

what the hell are you guys on about, saying "chill" and that other shit?

I simply gave him a few search terms what would bring up shatloads of threads where this problem has been explained so many times before.

Not point in me typing out the explaination everytime the question pops up, I'd be here everyday, replying to at least 5 threads a day, typing the same old shit, word for word. This would completely defeat the purpose of SAU wouldn't it? f**k, its not MSN messenger... Its a user information database!

This is a message forum - Like a dictionary - when you want something, you search before asking. I simply pointed him in the right direction, in a friendly manner.

The SAME questions get asked over and over again, thats why there is a search function! Sometimes, people just need to know what to search for, hence my post..

fark.........

:nyaanyaa: Good description.

Its often a fine balancing act of "Jelly bean, candy coated and answering every noob Q like it was the first VS bluntly directing ppl to the correct A: and spending our collective time on current unanswered issue's"

Yeh this is happening to me as well.. it goes bang pop bang pop which is boost cut. I turned the boost down and i think i'm just borderline.. not sure how it will go @ night might give it extra psi n hit boost cut. It goes up to 12 then down to 9 then creeps up to 10 just a little bit over towards redline. Strange thing about it is in 1st it goes 10-11 already n same in 2nd is the same.. it's quite aggressive and in 3rd to 4th.. sits comfortably in 9-10-11 depending how hard i drive it.

Still running stock ECU but gettn my powerFC tuned.. so i should b able to boost it up to 12psi right guys????

    • Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.
    • Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻   
    • Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”
    • Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2
