The 3.0 H6 isn't built to be turbocharged. Even beefed up. Ripped from mosc's words. It totality screws the suspension up. 500 crank HP can be had on a beefed up EJ257 shortblock with beefed up heads. 500 wheel horsepower is going to be a bit tough on a EJ unless your using a massive turbo, spraying some NO2, and using a block that's sleeved.
Edit: Normally swapping in other engines that aren't wired for our dash is really problematic to get everything working right and its down right a pain. I don't like the sound of the LSX swap...pushing that big V8s exhaust down a normal WRX muffler sounds like crap. Just my honest opinion.
actually the wrx rear end was just temporary to work out whatever kinks i had in the swap.....it broke after around 4,000 miles of spirited driving......my car has a nissan r200 in it now.....with a set of driveshaft shop axles......we are turbo'ing it now....this car is actually my daily driver......i got tired of climbing in and out of my elise everyday....and i like having something no one else has......i dont even care about making the car that fast......but it sounds mean sitting at a light....and eveyone and their momma looks twice at it everywhere i go.....you think they would have swapped out the rear end...
Why would a full ej257 longblock necessitate DBW? Why not just stick with DBC?Probably going to need to do a EJ257 short block with wrx heads. Otherwise known as a hybrid build. Unless you want to have all the hassles of switching your car from a DBC to a DBW throttle set-up.
I was referring to a full longblock with STI heads. The USDM STI heads are set-up as DBW. It's just easier to use WRX DBC heads if your ecu is 02-05 MY and do the hybrid build. From what I've been told. I mean, if it's easy to change STI heads to DBC. Then do it, but I've never heard that.Why would a full ej257 longblock necessitate DBW? Why not just stick with DBC?
OP: keep in mind if you decide to do hybrid build your static compression ratio will be slightly higher (~8.6:1)
