Default 3.0 h6 question again in a wrx..

i was wondering three things...

1) would the engine fit?
2) possibly do the 3.3 h6?
3) would it be beneficial in any way to have a sequential turbo setup like the the blitzen(not sure if u spell it that way) manifold on an old legacy if this engine fits?

I want to put at least a 3.0 H6 in my WRX then turbocharge it. Befrore putting it i willl reinforce out with internals. Also, i guess i have four questions, is the h6 open-deck? five that is...
Where can i get internals for the h6 to make it durable enough for say more than 500 whp..

i have the $ and the time to do it myself...

I don't know that much about the heads...you will probably want them worked on to flow better and for the stroker idea that should work as well just buy 1.5 stroker kits A custom turbo kit is what will be required...basically like turboing a RS and then doing.
Take it easy, Micah

The EG33 (SVX motor) has one exhaust port per cylinder. The new 3.0 (2004) also has one exhaust port per cylinder (saw it at the NAIAS show last weekend).

Just wanted to clear up any confusion and mis-information here.

If you can ask that question seriously then this project is not for you. A 4 cyclinder head is not going to be conpatable with a 6 cyclinder block. Also this idea has been disscussed before, do a search. And Yes the H6 will fit.

EG33 (SVX) is an open deck design.

You're kidding with the cylinder head question, right

Right here is where you are mistaken. The EG33 has one exhaust outlet per cylinder (3 total outlets per side). Not two like you stated above.

I was told the newer H6 only have one exhaust outlet per side...much like the EJ22's? did they change the design?
Take it easy, Micah

I'm interested in doing the same thing. After sourcing everything to build up my EJ I'm thinking I could do the same with an H6 for just two more sleeves, two more con rods, pistons etc. If only it would fit.. and as long as theres no weird H6 oddities that would make it not worth it.

Default Re: 3.0 h6 question again in a wrx..

Since I've put an 3.0 H6 in a GC, I suppose I should pipe in on this one...

the 3.3 is much larger. I believe that they have been turbo'd in the past.
Quote:

this question is not related to this particular topic. sequential vs. non is an entirely separate discussion, and has no special applications with the engine in question

You are going to have them all custom made, because no one makes performance parts for the 3.0 H6.

You've got $10,000 (after car purchase) and three months plus dyno access and custom ECU programmers available? Cool.

I can't wait for pictures. Good luck.

I thought the bore of it and the WRX were the same? as well as the stroke?

You'd be wrong about the 3.0L H6. It's obvious you haven't a clue about this subject. Here's a suggestion — wait a few years and save up some money in the meantime. By then, Subaru will likely be using a turbocharged 3.0L H6 in some production US vehicle. At that point, a swap might be possible.

WOW...sorry to piss you off man...just going off of what I had been told...now that I have done a search on google you are correct...the H6 3.0L has a bore and stroke of 3.51 in. (89.2 mm) x 3.15 in. (80 mm)
