hey guys im in a bit of a stuck situation here.....ill cut the long story short basically im at a situation where i cant figure out which turbo i want to use for my gsr (eagle h-beam rods with je 9-5-1 pistons welded block guard....skunk 2 retainers and springs...ferrera exhaust valves, honda intake valves and the head was milled) annyyyyway i have a mits turbo off a CAT thats a td06h-14c (http://aim.search.aol.com/search/ima...ry%3Dtdo6h-14c) that is supposed to be a t3 and i have a turbonetics 30430 e-57 thats a .57 intake and .63 exhaust.......THE PROBLEM....i dont want a turbo that fully spools so high at like 6-7 rpms but im afraid the tdo6h-14c is not big enough and will spool to max way to quick...anyone got some facts that can help me out

Your 57 trim, (I guess from turbonetics) will do just fine and will more than likely reach maximum pressure by about 3500-3800rpms. The Honda cylinder head is extremely efficient. Make sure that your head is not milled more than .030", and check your valve clearance.

well the only reason im skeptical aboutmy turbonetics is bc my buddy has the same exact turbo in his gsr hatchand it doesnt feel like it reaches full spool until about 6 grand....dont get me wrong once it gets up there it goes like any other turbo vehicle

If it is truely a 57 trim (going based off TheShodan's suggestion), then it should hit full boost by 4-4400rpm unless there is a HUGE problem. I ran a slightly smaller variant of the 57 trim (the GT3255b) and had full boost at 3800rpm. Also, if you're going based on the boost plot on the dyno, those aren't always accurate. I've had problems getting accurate read-outs on my tuning sessions. Most of the time it seems to spool about 1000-1500rpm slower on the dyno than on the street.
