http://www.vecco.net/ this is what i am starting with, it says i need injectors MAF and a long tube h-pipe. what kind/brand Maf should i go with i have a pro-m regulated for 24lb injectors but i was thinking i will need 30lb injectors. some one said something about a blow throw maf?

 

he doesn't need larger injectors. The two wastegates are debatable. Depending on the route he goes. There is the option of running turbochargers with integral wastegates, then he won't have to buy any. Or he could run one external wastegate. Two externals will flow the best if you can afford it.

No tune either. Not with an fmu.
& letting the engine get to operating temp before punching it. A fast way to crack an exhaust housing. I did it to one of mine. My friend did it to two in his car. I have pictures too! Still got the housing out in the garage aswell.
You'll need fuel management for anything above 1-2psi.
Either an FMU or FPR. With the FMU you are good to go after the install, no tune required & you can't tune an fmu anyway. With the FPR you can't run the car until you have had it tuned (unless you are good at guessing). You'll see more power with the FPR & tune.

 

Im pritty good at tunning stuff, what FMU should i look at? and it does not matter what the temp is out side my car does not move untill my temp gauge says 160, if it is 32 or under outside i let my thermostat open once or twice so i know if anything is frozen. also with the bov's i can get two of them with the kit should i? now what is the diff between a blow off valve and a wastegate? thanks for the help

 

Heres some good info that might help you out and I just threw some interesting stuff in there too.

a wastegate like fox said can be internal and external. for low boost internal is fine. not to get too in depth with that, but a external is less prone to boost spikes. the wastegaste is welded on you exaust before the turbo. it is used you regulate how much boost the turbo will make. it uses vacuum and a spring to open/close a valve that lets the exhaust spin the turbine or exit the exhaust. an internal reroutes the exhaust around the turbo and back into the exhaust (usually) and external usually just dumps the exhaust gases into the atmosphere (usually)....sounds loud because its like open exhaust. a bov is on the "cold" side or comressor side piping of the turbo. it also works with vacuum/spring. its main function is to release pressure when there is a sudden pressure drop so the turbo(s) keeps spinning in the same direction and doesn't choke itself. if you want to vent to the atmosphere you must have a blow thru maf mounted after the bov so it can get an accurate air count. or you can recirculate with a hose that goes back in before the turbo. if you vent to the atmosphere using a draw thru maf you are venting metered air and performance will suffer (basically your comp "thinks" its getting more air then it is and will add fuel=too rich). many tuners that i trust have told me that draw thru provided a more accurate air count when you are moving alot of cfm's. hope it helps

 

Why is BBK garbage ?

 

ok where can i get a draw thru maf? so this is what i can do in the way of options what would best sute in the way of bov and the wastegates. ok im trying to understand this a little but if i had a draw thru maf with a bov that vented into the atmosphere that would hurn performance? what would be the best bov/wastgate set up for a street car? thanks again for the help

Dual or single BOV Price=$99-$189
Stainless Turbo Heat Sheilds Price=$179.00
In Car Boost Controller Price=$52.95
Dual Port Wastegates Price=$69.95
Polished Piping Price=$39-$189.00

 

draw thru = maf before turbo (attached to air filter)
blow thru = maf after the turbo
i would recommend a blow thru setup since you said you're not going to be moving too much air then you can vent the bov to the and its awesome. it scares the hell out of people when they have their windows down. you have a lot of fun. look in my last post and it'll answer your question killing performance because of venting.

 

ok well i know for shure that is how the kit is set up becuse the maf is on the pressure side of the turbos after the intercooler it is in the fender that is where they put it, then they have weastgates on the turbos i think and a blow off valve somewhere before the maf. and i was thinking a draw thru set up would not work on twin turbos unless that had a pipe connecting the two of them. becuase you would nedd to MAF sensors. also where can i get a blow thru maf? and what fuel managment should i look at? thanks again for the help you guys are really saving me.

 

Tims88gt, not tryin to steal you thread but im confused. Isn't a blow through maf what you want when you have a turbo. Every set-up I looked at has the maf after the intercooler and then the pipe goes to the throttle body. Also is the main thing that a FMu does is adjust air to fuel ratio?
