Need more information to properly answer your question. With what kind of fuel/MAF upgrades? You will have to have bigger injectors/bigger MAF and some sort of tuning to let the EEC know you have them for proper A/F ratio mixtures.

Area 91 runs a 300hp (crank) NA motor with all bolt ons on a stock computer.
Blown engines , i donno , i guess 300hp if you leave the injectors stock , they are maxxed out at that point.
Like the other said , what you got in there?

You're kidding, right?kzoosho said:
If you're going to boost the car, buy the TwEECer or get it tuned, and don't fool yourself into imaginary plug-and-play scenarios with any MAF.
Otherwise just leave the car alone.

shobrosgarage has a 75 thats plug and play so no im not kidding

if your going to boost the car it is advisable that you atleast get a non rt one like I did. i'm running 10psi intercooled on a PT67 unit. I tuned my car using a AFR gauge and pulling the plugs a lot.
edit: a couple of people have had some sucess with rising rate FPR's but you will be rich if you go that route. if you want this to be a daily driver then get a tweecer nonRT and you can get yourself a pretty good tune. **** I still get 30mpg on the highway... about 15city
but that my own fault.

Sure, a Pro-M (or whatever they're calling themselves now) can work OK on an otherwise stock car, but change it from a suck through to a blow through and it's no longer plug-and-play.

Every blower car I have seen has an LPM, bigger injectors and 80mm MAF. I don't know if the stock ECU and injectors can handle boost. I do know if you run lean on a blown car you risk destroying pistons. It has been my experience, that everytime I tried to go the cheap way out, I have been burned bad. If you are going to FI the engine, do it right.

i understand what you are saying jed but what im sayin im not planning on running an ungodly amount of boost(well at least not on this one) just want to run a smaller turbo and from what i have read the stock injectors can handle 300 or so. the stock ecu is what i was worried about that was the rason for the question and since the lpm isnt available any more i was hopeing to get away wih out having to buy the expensive tweecer twice seeing that i hav eto buy one already for my other 92. everything else is done right as far as pipping seeing that i am getting the piping form bitterswetsho its my old turbo i had from my 92dsm and was looking at a 195lph walbro and a 75mm from shobrosgarage thats all i mean if i have to get a tweecer i have to get it but just wondering if i could without it thanks

3.2 MTX SHO
i believe stock 3.2 injectors run 320 as i have heard. i know 3.0 and 3.2 are olny different by .5%
i also believe if your gonna do it do it right... if you dont really wanna get a tweecer then at least get enough guages so you know what the car is running and safely.
tweecer r/t is like $585 or something.
personally im gonna be attempting a turbo setup and hope its gonna be close to finished by this time next year (dont wanna have it done in the winter ill be itching to try it but o well) im getting the r/t and much stuff as i can so i cant honestly say itll be done but im hoping.
i think you could get 320 crank outta a super or turbo on stock injectors, id go bigger.
as far as how much you could get out with bigger fuel pump and injectors etc. i'd think probley a little more then 300 whp with no tuning if you know what your doing.
be damn careful tho because you dont wanna pull out piston chunks outta the oil pan lol

SHOnutperformance.com has modified the new style accel (search for more info on new vs old) injecters to work in the SHO. pick up a set of 44lb or 47lb. get a lincoln 80mm maf or a lightning 80 or 90 maf (all depends on what you can grab cheap) if you get a lightning maf you will need a adapter harness that is offered from shonutperformance.com or you can make one. a gt35r or similar turbo.
you can use a atmosphere BOV if you use a blowthrough maf that is after the BOV without any tuning issues, but some prefer a recirc or diverter valve rather than a BOV.
I would not reccomend trying the stock ecu for any boost. the stock ecu has a "targer AFR" value that is set for 14.7 so under boost it will try to tune for 14.7 and you will likely destroy the pistons from high EGT's. I am tuning with a non RT model (sold at shobrosgarage.com) I selected what maf i'm running (lincoln) I modified the table according to the info on here, changed the targer AFR to 12.5 and pulled a bit of timing out. not the best tune in the world but it didn't blow up yet and I get great milage with gobbs of power.
*injecters
*maf
*tweecer RT or NON rt (non RT is -200~ )
*wideband O2
thats your list for engine management
