h6 swapouts? any thoughts or advice?

Plus, the exhaust ports are DIRECTLY over the crossmember, not in front of it, so the header is going to have to be squished a bit and go out the front before it turns to go to to the back of the car.



This is what you RS exhaust looks like:

Huh, my bad. I didn't examine it closely.

FYI, mine don't look like that. Mine look like this

And mine looked like this for awhile

Interesting setup.
How did it do?

Bout the same as any full exhaust, around +15hp. On the dyno, it showed about that much but with an intake too but that was in wheel hp of course.

That was a header from a JDM EJ20R Legacy, 4-1 header going to a 2.5" flange without a catalytic converter (the US model 4-1 headers have the catalytic converter right there). Only one on the country that I know of (imported via JDMparts.com), no idea what happened to it after I sold it though...

(sorry for the hijack btw)

how about a supercharger on either the h4 or h6 with the engine being lower and giving the probability of more hood clearance(or you can buy a hood with a scoop and be raised a bit if things don't clear easily, toyota has superchargers with built in air to water coolers in the manifold so you would do away with all the piping + better reliability, maybe it will have a secondary tune programmed into the ecu like the 00 - 07 corolla 1zz-fe engines where you can plug and play a supercharger and the ecu adjusts automatically...( im talking strictly about the corolla fyi i know modifications had to made to make the supercharger kit work on the celica/ poniac vibe)

Ya, HUGE amount of room in front of the engine for sure:

I wouldn't be surprised if we see one or two H6 swaps showing up next year, maybe at SEMA or another venue.

Ya, but one motor is so different than the other people just started calling it the EZ30R (along with how they called the cars 3.0R and such).

Turbo would be the easiest option. Customize a 10'+ Legacy GT setup.

Wow, looking at it in that sort of mindset, you're right. That engine bay is huge. It's reasonably long and very wide. I think we may see quite a few engine swaps in this car.

I'm concerned now that the motor might be too low for that turbo layout, and the headers might not clear the space between the subframe and engine.

I HIGHLY suspect the engine placement is a good reason why we haven't seen any news about a turbo motor yet.

Viper V10 swap?

[old greg]

I really doubt it.

The Viper engine is 34" long vs ~18" for the FA, you'd have the throttle body sticking out of the hood.

An LS1 is a possibility (~27"). But for the Toyota faithful what may be more important is that the width should leave plenty of room for a DOHC V8, such as one of the UZ or UR engines. It should also allow stuff like the VQ37.

The OEM spec hood is too low for any big V to go into that car. Small front mounted super charger would be perfect for it, extra power gain without changing power delivery characteristics. 12.5:1 compression seems high until you consider that engine has direct injection. Just replace the direct engine fuel injectors to larger ones and disable the port fuel injectors. Custom ECU will be needed along with bigger fuel pump of course.

I think H-6 swap is completely viable. All H-6 engines are same as over-square 3.0 H-6 in outside width and length. Engine mounts can be fabbed easily from steel to arrange the location by a couple of inches forward and up. The biggest issue will be mounting the 6-speed transmission to Subaru engine that might have different bolt patterns and flywheel + sensors. So a viable option is to put in the original Subaru AWD transmission along with the engine and pull out the font drive shafts. Lots more work on transmission than the engine.

Never mind, it was their trans mount making the exhaust routing like that.

All that piping for a major case of turbo lag.

That's what she said!

There is a TON of room for the H6 in the engine bay!
