No Its the EJ22T pistons that lower the compression not the Rods

I have missed out on many chances on buying an impreza.. sucks

anyway if I get a 6 speed front differential, and rear differential with a DCCD all from the same year WRX there should be no problems right? with a DCCD to put most/all of the torque to the rear wheels for some fun times every now and then, would the DCCD handle the power of the H6?

they'll probably notice that the radiator is in a different place, and you probably hacked up your radiator support to make it fit.

DCCD is Driver Controled CENTER Differential. It's in the trans but yeah anyways.... Getting matching final drive ratios of hte differential in the rear and in the trans is the key. You can have them swapped out by a shop to match which ever final drive you want. I'm getting a V6 STi RA w/DCCD trans form DS1 and though it comes with a 4.44 final drive I"m likely gonna have it swapped down for a 3.54 or 3.9 and put a R180 rear diff. Wether or not your choice will hold the power is up to how you drive and what you will use the car for. Talk to a trans specialist(Like DS1 Motorsports! DYLAN RULES!) and figure out what you want to do. You can run the original bits if you don't beat on them at all atleast for a little while. If you are spending the money on a 6speed just make sure to get a matching rear diff. Either a "built" WRX R160 with matching final drive or just get the matching R180 STi rear diff. Good luck with that but work on the motor part first. Either you add a H6 to a set up car or you swap a h6 into a car and build around it. Well there is option 3. Over haul the whole car with H6 and everything else while the car is off the road(my choice)

Since this is the official h6 impreza thread I thought I would post here about my potential eg33 swap into a 98 forester. Ive seen motors online and Im wondering what else I will need besides just the basic motor. Obviouslly I will need the main wiring harness for wiring. So I would really appreciate it if someone could add to my list of things I will need to complete the swap.

Thanks in advance,
David

the engine with throttle body,
engine wire harness,
ecu wire harness (the part that goes through the firewall),
ecu,
headers although you'll still need a custom exhaust, but its a good start,
to fab an intake that will work with your engine bay.
you can use your tranny and existing mounting points etc, thats all the same.

If you are RS25.com too search for a thread titled H6 it's kinda the same thread as this but very specific to first gens and most talk is about EG33 swaps.

Some great info in this thread, keep it going!

Does anyone know of any companies that are making aftermarket non-AVCS cams for the H6? I;m trying to compile a list of everything i want to get before i start tearing things apart.

EDIT: Also does anyone have the specs for the different Stock cams available for the H6?

bump!

each of the engines have only one cam profile set per engine. So the EG33 all only have one stock grind, same for the others. Delta Cams can work on any cam profile you want.

RB injectors are supposedly the same as SR injectors, so that would be a good option for you.

They indeed are aside fromt he flow rates. Any average Subi injector will work too. Anything that will work on a 92-06 Impreza/WRX/STi will work. Deashworks flow calculator points that for my goals on the EZ30R a floow rate of around 400cc or higher. So I'll be looking into a set of STi pinks or other 600cc's to push further for later goals. But yeah the SR and RB injectors work.

You can order just six dirrect form deuchworks. Could just get 2 pairs of 4 and have spares. I will be ordering 3 pairs since I have two H6's Well when ever I get to it. Besides on ebay you see sets of JDM pinks and stuff where one is shot so it's basicly a set of 3. You can always just double up on that.

FYI, I case someone else needs this info:


I plugged my scope into my H6 EZ30R car to take a few measurements.. I didn't have the RH cam sensor wired up, but I'll do that tomorrow and take another snaphot.



Here you can see the 5th falling edge after the single large break which is TDC #1. LH Cam pulse is right about 70 degrees after that, just as the specs above.



Here you can see the start of the fuel injector spraying. Interesting that it is spraying starts about 12 BTDC and finishes about 2 ATDC. The intake valve opens at about 3 ATDC.



Here you can see the coil charging the firing the spark. The dwell is evident (and a bit high.. I need to turn that down some), as well this is at idle where timing is ~ 16 degrees.

I'll follow up with the RH measurements.

Yes the engine is close to the radiator. All EG33 H6 swaps into Imprezas will have that issue without converting to RWD to nullify the need for aligning the front axles. Some do try to scoot it back. DS1Motorsport's company project EZ30D swap is scootched back some but not much. The EG33 is a LONG engine so the better option would likely be to just move the radiator a little more forward. BTW.... THAT"S A HUGE F'ING TURBO! :drool: So what about the project is unfinished? Looks mostly done to me. Anywho good luck and let us know if we can answer anything else.

Did you even look at where his radiator is in the second pic?

You can move the motors back but its just a little bit. You start running into other issues aside from front axle length, driveshaft length, changing mounting holes on trans and motor, shortening the pitch mount, start to have issues with power steering lines and location as well...oil pan to x-member clearance too.

A few things to think about for a little bit of room

The Brighton was the stripped down AWD model. I believe it only had the 1.8l (not positive). The L had more luxuries and the 2.2l.
