Twin Turbo Help

I guess

BTW, I work at Wheel to Wheel. i understand a little about LSx engines and turbos

The beauty of a turbo is that you can turn the boost up or down if needed and going with a bigger turbo can generate turbo lag which keeps the power levels higher so it's not a bitch to drive on the street at lower rpm's.

I figured that, that is why I could'nt understand why you were posting what you were?

That power can be done with only 8 psi, so you dont need much of a motor buildup. Just a forged rod and forged piston with basic aftermarket heads. You will be able to do this fairly cheap, just know what you want to buy before you buy anything.

Ditto on this answer. You won't need much to make that kind of power and you won't have to spend tons on the engine. Fabbing the rest of the set-up will be expensive, too, so save some budget for that.

Getting into 10's with turbos will have less to do with making the power than with hooking. Hooking is hard in a Pro-Touring car in street trim. So plan on an extra set of tires. 10's on Z-rated tires is difficult.

Correct me if I`m wrong, but turbo motors don`t need to see high rpms to make power. 6000 RPM would be plenty of power making RPM`s, right? RPM`s is what generally kills cranks. So a TT LS1 stock bottom would be plenty of strength. Might want to put better pistons in to handle the extra heat and boost, right? LS1`s can be picked up pretty cheap these days and make very good candidates for a street driven TT setup that makes a lot of horsepower at a minumal cost.

I am not sure about the LSX's, so can't help you there. But for a normal small block to handle 550RWHP, you need a engine that runs! The first engine in my 69 (for turbos) was a wore out, hone job only .040 over, "Badger" brand (Cheapest I could find) hyper pistons, stock rods (and bolts!!), cast crank, 2 bolt block, small turbo grind cam, JUNK 882 casting heads, Victor Jr intake and Holley 650 with 2 junkyard T-Bird turbos blowing thru a GOOD intercooler into it. Worked GREAT for 2 1/2 years and about 15,000+ miles of me beating on it before the sloppy bore allowed the cheapie pistons to loose the skirts and finally split the cyl wall. The car was still running great (actually at the dragstrip) when it started puking water out the pipes. That combo had 500RWHP with a BAD rich tune (like not even on the wideband!) and was running WAAAAY low 11's in a car that did not work at the track, that day it was going into the 10's for sure. BTW-3.00 gear also!
That combo cost about $4,000 TOTAL! If you want stupid power, that is another story, but just to run mid 10's, it don't take much if your car works at the track. The most important thing is to keep a good tune and keep it out of detonation. Cheap parts will work just fine at that level if it stays clean!

BTW-Good (expensive) parts are generally longer lasting and probably better and more advisable (........and yada, yada, yada......), but I am just saying that they are not absolutely necessary if the funds are not there, you do not have to have a "billet" engine to make it work good

well i know a 05 z06 with a cam and tune can get close to the 550hp and yes is very streetable lol ....but as for an lsx with a twin turbo hmmmm once you nickle and dime it ...then it all adds up to a lot unless 10k+ means cheap to you guys lol
