Car put down 450 and I would like to take it to the next level and see it put down around 700hp. What would I need to change to see around 700. Current mods are
Ams 30r kit
Turbo xs intercooler
2.3 stroker
272 cams
Ported stm intake manifold
70 mm throttle body
Ets upper ic piping ams lower piping
1000cc injectors
Busher trans
Exedy twin
deatschwerks 300 fuel pump
Grimspeed 3 port boost controller
Currently tuned on speed density by boosting performance

 

bigger injectors, maybe different turbo not sure what the one u have rates to, how big is the intercooler?

 

that turbo won't hit over 500 on a regular dyno. Question is what fuel are you planning on running im guessing E85. You will need a upgraded turbo, injectors,fuel pump and possibly clutch. Could come close on a Black or will hit with a 35r.

 

or a 6262 bb or 6466 and way more lol

 

Would doing over size valves and porting the head be worth it. Was also looking at the jm fabrications intake manifold.

 

I wasn't really heading toward the e85 rout but if that's what's needed to make big power I probably will switch over to e85.

 

The intercooler is 3.5" x 11.75" x 24"

 

on pump better have a badass build for 700, I HIGHLY reccoment e85, I made 730 on stock valves and stock port on a 6466 and e85 before on my old evo

 

I think I'll be switching over to e85. I've already spent 1000s on others parts e85 seems to be the most cost effective way to to make big hp minus a bigger turbo

 

This will get you ...

yeah e is loverly

 

5862 Gen2, 2150's, Kelford 280's or ((shameless plug) GSC R2's I have a set if you need), twin fuel pumps, E-85 should get you there.

 

A 5862? not a chance, it won't even get you in the ballpark. That's a 64 lbs/min turbo. And if it did, the shaft speed would be outrageous and wouldn't be long for this world. You'll need to run E85 and at LEAST a 6266 (or older 6262).

OP: You'll reach the knock threshold on pump gas too soon to get to 700whp on any turbo that's not outrageously sized. With E85 you can get there with a 62mm (like a 6262 or 6266) without much issue. If you want some breathing room, get a 6466. Of course you'll also need to accompanying fuel mods...etc.

Take a look at the Gen 2. The OP also said around 700. The 5862 Gen 2 will be a fast spooling 700-ish turbo, and will keep the car fun.
