Turbo Gurus questions for yall

[Spyder]

ah, so i guess get rid of the greddy evo cat?

i was typing that as you posted that you had a cat back, you have 2 options here..

1-sell it and have enough money to do a crush bent turbo back exhaust
2-keep it and have them put a flange on the turbo-catback section where you can bolt it up to the cat back you have already purchased. this eliminates the need to buy a muffler and such and makes it so rear section (only section that will be seen) is pretty, if you care.

ill go with #2. so if i go with the #2 route, i can keep the muffler, and then just pretty much get rid of the piping and get the 3" piping from the downpipe all the way to the muffler?

you didnt have the gauges listed bish :P

and damn i got owned on that one

yea instead of buying a cat back you need a cat forward

you don't need a 3" exhaust for 250hp... i'd say stick with your catback you already have and have the downpipe fabbed to fit to that point. slap on a high flow cat converter and you'll be good to go on exhaust. as for the BBT28 turbo, if you're looking for the ones off nissans like the S15 turbo you can get them for around $700-$800 new, and in used form generally about $500 in good shape.

370cc injectors will be too small if you're looking for 250whp... you'll max out their duty cycle very quickly and find out the hard way you need to go bigger. i'd go at least 440's if not 550's just to be safe. i'd recommend some MSD injectors if you need to buy new top feed style injectors because they are priced about the best. or like spyder said used DSM injectors are a great bang for the buck.

no need for an external WG on this setup either. all of the small turbos mentioned will have internal gates and those will be plenty fine for the power you want. plus it's another money saver there.

and to add to your list... set aside a hundred bucks or so for misc. piping/fittings for oil lines, water lines, intercooler plumbing, clamps, etc.

btw, good luck on making that motor hold that kind of power without any internal work . "boost it until it blows, then upgrade"

if you are building the motor it changes things.. i was going off the assumption it would be on a stock block.

the mitsu T25 from the eclipse is a great turbo.i got one off ebay for 40.00 just make sure you dont buy a core. make sure shaft play is little or none and that it spins freely.and its not cracked on the exaust side where the waste gate dumps out,thats a common problem with these turbos. and if you buy a t25 it will proably come with a internal wastegate,if i were you i would run it and use a boost controller to adjust it.thats a way to save cash. good luck
