Go look at the dyno page to find your motor setup you will see how easy it is to make 450 to 500

Yes, 5858 is a great deal and I'm a garrett fan boy that likes to pay tomuch.

The pte5858 with BB upgrade is a direct competitor to the gtx3076r. Both have similar hp, 4inch intake, 2.5 exhaust.

Hell for his 450-500 goal I'd say go with the 5558. Bit smaller, bit less lag, but everything counts when you're actually trying to run fast 1/4 times.

Not even going to comment further on this. Can't help everyone, he'll learn on his own I guess.

I already have the nitrous on my car now it's just not enough to get me where I want. I already have it so I might as well use it. I'm fibbing up my own kit and will be cheaper than all the turbo kits built by the performance companies. But I am copying some of there ideas for my kit.

Nice not having to pay for R&D, just copy.

Here is a hint. In the 1/4, the race is over before you even hit the 1/8th mark. You need to focus on good 60ft times and keeping your car in the powerband as much as possible before the 1/8th. Going too big of a turbo with too big of an A/R housing size is going to kill your times, even if you may make more peak power than the 86 next to you. Take some time and review the dyno thread, see where these cars actually make power on 55-67mm turbos, and go from there. You're not going to run good times making all your power past 6k RPM.
Thats not that big, I ran a .82 a/r housing on a t3 vband with no issues and good spool on a 5858 Ball Bearing

You seriously dont need nitrous, get yourself a 5858 bb and good tune, you should be building 5 - 6 psi on ecutek launch control which is more than enough to get going.

In the drag racing world, lag means nothing to us and power/mph means everything lol.

Thanks for the help. Correct me if I'm wrong, but what I got out of all the help is get the 5858 with a big a/r and launch control and I should be good. But shouldn't I just go with a 6262 they are the same price and if I ever want to make more power the turbo has a lot of room to make more power. Just want the experts opinions on this. Lag doesn't really matter I'll get the trap speed from the spool go big or go home, but I could be completely wrong. I don't have any experience with turbos only cubic inches.

My philosophy has always been run the smallest turbo that will do the job. Sure spool isn't the biggest concern with drag but you still want a fat mid range, going to big may give you the peak number you want but your mid range will suffer.

Far to often guys build there car for some "down the road" scenario that never comes together. I have been developing my car on a turbo that most said was to small, gets no bar stool attention. However anyone who has been involved has just been blown away at what has come out of it.

This argument over the 5858 vs 6262 seems to be the same as the gtx3076r vs gtx3576r fight.

Hell if you want room to grow a 6062 shouldnt be much laggier than a 5858. But unless you want to go stupid like Justin & I a 5858 is more than enough turbo
