The Precision has been putting down great power and it would be my first choice.

What mani are you going to be mating this to?

 

If you want to save a bit of money, consider the BW S256. Great turbo, great price. Otherwise, the billet 5857 is also a great choice, but I wouldnt use the journal bearing. The DBB versions are ~$1450-1500.

Both will make better power than the 3076R, which is great for pump fuel. I wouldnt bother with a .63 a/r, just get the .82 right off the bat. The spool really isnt much better with the smaller housing, but the top end is noticeably worse.

 

i need a bit of help deciding what mani to get with i just dont want a log style. and i think that a front mount would be the best choice i just dont know brand.

 

GT3076R should use a 0.82 a/r turbine housing. I own both and have data logged both. The 0.63 doesn't really spool faster and makes less power once boost begins (which is a HUGE portion of the power band). All in all, the 0.82 feels better and makes more power.

I would personally say go GT30R. The GT35R is an awesome turbo, but for 450 whp, GT30R is the way to go. (unless you go with a twin scroll T4 manifold- then I would probably do the GT35R) The GT30R should max out around 550 whp and just a few years back would have been considered a large turbo for such a small engine.

You're 100% right saying tubular is the way to go. Logs tend to have more issues with bolts breaking and backing out, plus they make a lot less power and don't feel as good to drive. (Again, I've run both.) Go tubular the first time and you'll save yourself lots of $$ down the road.

sorry i meant .82 a/r, what brand or brands to go with on the mani what is the most resonable and or best i hate spending 1500 on one

 

I can't decide it's driving me crazy God please tell me what turbo to get!

 

Question for you: How much of the time do you rev to redline?

Not much point in sacrificing mid range for a top end you'll hardly ever use.

I vote for the GT3076R. I run a 3071.

 

U know what after reading this I'm gonna go ahead and change my choice to the 30r, I just drove my car and can say I don't want anymore power, the 30r is still a monster and the car pulls like crazy, so for a sick street car I'm saying go 30r, the bigger powerband is just more fun, I make full boost at like 4000 rpms , also the tubular manifold is a must

 

What full boost at 4000rpm wow impressive how much boost though?

 

17 psi, its def making that at 4500, its hard to keep ur eyes on on the boost gauge when the cars flying
