Hey guys,
I'm getting tired of the power the EJ20R is giving me...I'm as well starting to have various issues with my current longblock, so its time to upgrade.
My car is a 95 Legacy. I have a full stand alone (Megasquirt), Walboro 255, fmic, rotated, etc.
First, I'll start off by saying my goals. I would like to put down between 500 - 550 on the local dynojet. I would like to do this on 93 octane pump gas. I know its difficult to do, but its been done before.
I'll be using the EJ257 block with a built bottom end. As for the heads, I think I'm going to keep the EJ20R heads, but send them out to be rebuilt and port/polished.
I guess my biggest issue is what turbo to use. My TD04 will never provide much more power then it already is (its tuned at 15psi)....What route should I go for with the turbo?
Injectors are another area I'm uncertain of. I'm using 660 side feeds right now. Will I have to bump up to something like 1000 top feed? As well, is my 255 fuel pump enough to support 500hp, or will I have to run dual pumps?
I'll be doing the build myself, however I will send it to Topspeed (http://www.topspeedtuned.com/) to have it tuned. A lot of the local Subaru guys have used Topspeed with excellent results.
Any advise you guys can give me would be great. I posted something on NASIOC some time ago, but didn't really get any straight answers.
