he probebley had a manual boost contorller that he took off before you boght it, they are able to do 12psi for the stock turbo, but i would go to a exguhst system, 2.5'' or 3'' and a blow off valve, then go to 12psi with a boost controller

ya it what in a 93 240sx, it all depands on what year he is putting it into, some are litter than others, the sr20 has so much potental it is crazy, his was a stock sr20 i think they push like 200hp+ form sotck, so if he is putting it into like a 89-91 modle, he would be faster then the 93 becuse of weight, the 89-91 models weigh like nothing, so that would be a close match, it depends on what modes you have on yours, but see i will try anything and everything at leas once just to see where i stand, so go for it.

you can replace the boost soleinod, i dont think you can replace the wastgate one, only with another wastegate soleinod, is yours a 88-89 starquest?

ya you need some onther weard s*** in order for the timer to work, ya if i were you i would just sell it and not even bother, i am disconeccting mine and gooing to go with a manual boost contorller, with a switch insid the cabin to work it, hopefully that will fix my problem, and some one tolled me to unpluge the wastgate hose and if it stays to the max psi then it isint your wast gate so i did and it stayed a 20 psi for one hole run, then i pluged all my s*** back up and then right back to 9.8psi, so i am hopeing the manual boost conrtoller with fix that problem, if not then looks like its time for a new turbo.

did a roll start last night with a black top sr20, suckers are fast, but not fast enough, for my car who i call turbo tom lol, anyways for those of you who dont know what a roll start is, its were you stay in 1st gear cruse at about 10mph side by side with the guy you are racing, and when you get to the line you flor it when the guy flaging drops his hands, its fun as hell, got his but by like 3 cars, he was socked after spening what he said 1,800 on just the motor not to mention having it put in.

no i dont have the turbo timer hooked up, ya dont need that to function, i have the start psi set a 8 psi so that is when the waste gate is set to start to open, i have my gain at 45%, it was running very good at that holing 12psi like i wanted all the time, o ya and low boost what 7.5 psi for town and 12psi for racing, i love the psi at a push of a botton, so i am realy upset that it wont put out any more then 9.5 psi right now, and i dont know why, i unpluged the vacum hoses to the silinod and set it up for the wast gate to open up at the stock settings and it still dose 9.8 psi, so that is what got me thinking it was the silinod.

well there are a couple of things, i have the BCU+ boost controller i think the silinod is out in it, i am boosting a consnt 9.8 psi, i have my contoller at 12psi but it wont go that high, the waste gate is good, i know that, i was wondering if it could be the silinod and do those go out? if so i would just go away with the system and get a manual one, as far as modes go on my car i dont know if that maters but they are as follows, 3'' straight exgust from *DM, hard intercoller pipping with greddy BOV, GM MAF from lsi camero with translater, balancing elimination kit, none jet valve head, TEP cam shaft and springs, and what cars do the 19c turbo come from?
