Bolt on opinions.

[junglehicks]

Got a 6 bolt 4g63. Stock internals, gt30/40, bit of a fuel system. old haltech e6k. Thinking I might put it on e85 and a set of cams. Much gains to be had? It made 320ish hp. Opinions? Its Rwd by the way. w58 behind it. In a gc galant. (sorry if this is in the wrong section)

The usa guys say 500hp at crank is about the limit on std pistons/rods.
I would say boost and e85 will get you to that. I think its about 80hp more than your 320 awhp, using 25% as your driveline loss.

What boost was it running before.

Sounds like a fun toy

Yeah its running at 18psi, that would be awesome! If I make that sort of power Ill have to go auto and shoot for 10's!

Cams for a 35/40 would be a good idea- grab yourself some late model EVO valve springs while you're at it. I picked up a set on EVO OZ for $100 shipped.

E85 is very popular these days. We all know why!!

for E85 you would want to get a walbro 400lph intank (or equivalent), 1000cc injectors, and a wideband if that's what your ECU requires...
