Ive been reading and from what ive read ppl are running like 5 lbs on the stock fuel system? Is that right? Stock pump/ injectors no fpr noting? If thats right i will bolt my stuff up in the next week and run 5 lbs till i can get the rest. I have a built bottom end so i will be running 15-20 lbs eventually, but id like some boost in the mean time. The accuator i got is the 10lb one, so im thinking of just getting an MBC (manual boost controller, <- for the new members, like myslef who dont understand all the terms) and tune it down to 5 and id be set. Also at 5lbs i dont need an intercooler so all i would need is a bov and piping. LET ME KNOW, lol, im about to take the wastegate arm off the flapper and run like 2lbs, i want BOOST!!!

Yea forcefed is right on. You could always do the actuator mod to lower your boost http://www.denverspeed.com/wastegates.html. But you will need something to raise the fuel pressure in boost, like a fmu or better yet, a sfmu. Also go with the walbro 255 pump. The stock one wont be enough to provide enough fuel in boost. Injectors will be fine for low boost but thats it. You might as well do it all right the first time, like get a fmic if you plan on going up to 15 lbs of boost, you will need it.

a brand new fuel pump (walbro) and fmu (vortech) can both be purchased for under 150 dollars on ebay and installed in less than 2 hours correctly, why would this be holding you up? also in my opinion you need an intercooler no matter what your boost levels a are, yes it is true that its most efficient with higher boost levels, but your alot safer at 5psi intercooled than you are at 5psi non intercooled, its just the facts. like what was said b4 if your gonna do it do it right. and i might be wrong but this post should be moved to the turbo section. as it deals with boost

and for what its worth, he have a nice little section on here we affectionatly like to call the "TURBO/NITROUS TECH" forum. it has a more than a few nuggets of knowledge that may be of interest. the reason its there is so that posts like this about turbo stuff can go into a central place so that one may later search for their answers and find what they are looking for...

thank you to the guys who have answered this question, but you should refer the origonal poster to the appropriate section...because all his answers are already there.

USED TO HAVE...Everything you wish you had, and then some...

You are somebody special Tim, you matter! - from the admins (but nobody likes you, because your username is just like that other guy's, and you whine a lot)

You know what, I'm currently preparing to build a custom kit and I plan to summarize all the theory I read on this site so that it saves other BANME!s like me time and money. If I do it right it might even go on the tech page

I really want it hooked up! lol, and there is no saying how long it will be before i can get injectors put in/ get a safc2 and an fmic. If i take the wastegate arm off the flapper that would mean id be running like a 2lbs, rite? Ill get the walbro 255 and the fmu for now, untill i can get the rest of the parts. The thing is that with 8.0:1 wiseco pistons thats a bit of power lost there that i want back,,

How does this sound for boosting at 10lbs?

walbro 255
12:1 fmu
30 lb injectors

should i go with the 12:1 or the 10:1, i hear the 12:1 run really rich and as i have a built bottom end i can afford to run a little leaner, what cha think? By the way thanks for all the good advice.

going to break it down for ya a little more. if you are going to use bigger injectors you will have to use a sfmu. the stock injectors are good to about 8-10 psi with a fmu. so for 10 psi i would use walbro 255, sfmu and bigger injectors. now since your motor is built why not get 440ish injectors and run 15 psi. so as a review:

255+stock injectors+fmu= no more then 10psi

255+bigger injectors+sfmu= 15 psi some people have ran 20 with 450's

That is exacaly the kind of breakdown i needed THANKS!!!!!



quick qestion tho, i got a guy who is willing to sell me the sfmu,safc, and the hrc inline pump cheap, would the hrc pump work instead of the 255?

yes it will work. you will still need bigger injectors if you want to run 10+ psi. people run 10psi with a 12:1 fuel to air set up.(weather it be sfmu w/big disk or a 12:1 fmu) i would not do this. to me it is like pushing something that does not need to be pushed.

Is there anyhow i can get like an 8lb accuator for my 16g? ill go as low as 5 but id rather not.

This really needs to go in the turbo section, im suprised it hasent been moved yet, hahn sells a 6-9lb actuator for the 16g its actually a 10lb actuator imo but it will work fine for what you are needing. if your intercooled. i have the walbro, fmu 12:1 and the hahn set up with 10lb actuator with no issues due to fuel cut, in fact im richer than id like to be at times.
