Ok guys, just wondering what kind of numbers i would put down (to the wheels) with this following setup:

SR T25370sEnthalpy Tuned EcuSSA bottom mount mani3inch dp3inch cat back3inch test pipez32 mafSSA FMIC

Did a compression test ive got 150 on all four cyls. so im just wondering what this small setup will put down. Im hopin to hear somewhere around 260ish-280ish, but idk just wondering what you more experienced KA-t guys think. Thanks for the help in advance.

A fuel pressure regulator, bov and a good dyno secsion.

Also be aware that 150 psi per cylinder is a pretty low compression. Your set up should net you around 250hp ish but the question is can your motor take it.

Just be carefull and get a good tune.

Take care.

definitely get bigger injectors just because why spend the money on an ecu upgrade when 550s will give u room to max out that turbo while still having fuel to play with. price difference b/w the different sizes of injectors are about 3 tanks of gas.........u'll thank me in the long run.

but if u truly will be happy with just 370s, then what u have on that list sounds good to me.

i want to run the same but with a t3/t4 and a custom manifold...

how about those rx7 460 CC injectors. i have a set of those and sr 370cc...i'm leaning toward the 460's. will that work better, because i already have them...

well for a t3/t4, ur gonna max out those 370cc injectors fairly quickly............i suggest using the bigger ones. the rx7 ones are side feed high impedance im assuming?

Ya i forgot to include the oil lines and the rfl...was in a rush posted before school but ya...ill have the bov, and a 255 walbro. Do you really think ill need a fpr though? I mean I can see the reason behind 550s, but why would I need a fpr? Just tryin to learn from the more experienced members. Thanks for the input so far, hope theres more to come, you guys are great!

Thanks,Ed

Having good fuel pressure in the line helps take the stress off of the larger injector's and fuel pump too.

The less your entire system has to work, the longer you'll get out of it. Some people think it's overkill but a couple of guys I know who said blew there motor and came back to me saying "Man why did'nt I listen to you"

LOL, I laugh at them. Always better to be safe then sorry.

Both the T25 and 370s are good until ~240-250rwhp safely.

So you're maxed out there...probably ~10psi from that setup.

I'm sorry, I still can't get past 150 compression. You cannot hope to turbo that. Or Ka-boom.
