Project: 99 Eclipse GST Motor Pull and upgrade

[sleepydsm]

I'd say a refreshed 6-BOLT STOCK, with a nice headgasket, good tune, and some L19/A1 headstuds you can make really good relaible HP

I am on a stock 6-bolt shortblock, stock headgasket, regular ARPs, and my car makes 450awhp at DB no problem. I've been making over 400awhp for about a year now with no troubles. I did a stock rebuild with ACL Race bearings, new rings, honed the block myself, checked all the clearences, etc, and slapped it together.

My 2 cents.

Get a junkyard 6bolt. Freshen it up. Do the swap in your car, make it pretty. That Billet 16G, with some E85 would be fun!

Definitely need injectors over 1000cc if doing the E85.

One Walbro 255 HP is enough for your goals

I highly recommend the FP Race exhaust manifold.
