Im doing the DIY turbo route and only want to run about 9-10# MAXIMUM. Wut ever gets me closer to the 400RWHP mark either 9-10 lbs is fine. I was wondering besides the blowthrough MAF if I could run twin turbos on 24# injectors as long as I didnt get crzy with he boost? As everyone knows Im trying to do this for as cheap as possible but obviously leaning out and thrashing the motor isnt an option. What is the highest amout of boost I can run with the lowest sized injector?

I personally wouldn't go any smaller than 42's. I'm not a believer in FMU's

OK, now with this blow through MAF, is is a necessity? I have ones of those C&L powerpipes with a the mass air meter calibrated for my 24# can i just recal it for 42's and get the injectors?

with a c&l you should be able to by a new sampling tube for 42's and be ok....as mentioned, I woudlnt feel safe running anything less then 42's in a blown/turbo combination

OK so 42 it is, now wut exactly is a sampling tube? When I first got my stang I didnt know anything about cars, Im still learning and am on my second motor Ive built. The guy that I sent my car to owned a shop in Orange CA. he was bad. He never followed through or anything and said he put stuff on my car that isnt there now that I have learned where to look. ANYWAYS I have a receipt with all the stuff I had done. Im confused about wut these 2 items are.

ECM Mass Air Meter Calibrator pro-m - 269.99
C&L 24 lb Mass Air Meter & Downtube - 279.99
Wut would qualify as the "sampling tube"?

definitely use a 255 intank pump. I run a walbro 255 intank as well as a t-rex inline pump with my vortech setup at 10 lbs of boost. I have no fuel starvation problems at all.

Its a little tube that is in the top of the inside of your MAF meter. You can buy another one of those calibrated to 42lb injectors. Personally I don't like C&L meters and feel that pro-m is the only way to go, but if your budget its tight, then just get another c&l sempling tube.

255lph fuel pump and 36#'s would be as far as I would go. If you go single you can use a drawthrough MAF, but for twins you would need a blowthrough...

Many people have had problems using C&L's but SOME people have got them to work.

Click to expand...

The calibrator can only go so far...Yes it can change the voltage but it cannot change the width of the wires/electronics. Just buy a meter that was originally for 42's. I almost got one for a $165 yesterday but I caught the deal too late so just look around.
