amorgan93 Posted December 17, 2010 Share Posted December 17, 2010 twin turbo setup with uppipes and down pipes, one VF20 turbo, one VF21 turbo, no shaft play--From JDM EJ20G. Cylinder heads from JDM EJ20G DOHC and all 4 cams, but one is busted. Intake manifold from JDM EJ20G. Intercooler from something. pistons from EJ205 (not shown), no rods. i know very little about these subaru motors, but even less abot twin turbo setups. So here is what i have a 1990 legacy wagon with an ej22e n/a and a 5 speed trans + all the parts listed above what i want to do put the DOHC heads from the ej20g on my ej22e, use the intake manifold (which includes the ej20g injectors, all that good stuff) on my ej22e, put the ej205 pistons in my ej22e, and use the twin turbo setup on the ej22e. And buy the ECU from a legacy ej20 twin turbo. questions: How will using the ej20g heads and ej205 pistons affect the compression on my ej22e? Lower it/raise it from stock? Will the intake manifold work? Will the intercooler work? Is the ECU from a legacy twin turbo going to plug into my wiring harness? I'm new to anything turbo related but this deal was a 1 time only thing. i cant find ANYTHING about the vf21 turbo, and very very little about the vf20 Link to comment Share on other sites More sharing options...
BAC5.2 Posted December 17, 2010 Share Posted December 17, 2010 The twin turbo setup doesn't fit the LHD USDM cars. IIRC, one of the turbos interferes with the steering stuff or the brake booster or something.

FML! and i just noticed the cam that busted, the busted part is still in the cylinder head, and the metal around it is busted as well. so can i still use this head? how bad will that affect anything? and what is the plastic piece in the very last picture Link to comment Share on other sites More sharing options...
I Donated broknindarkagain Posted December 20, 2010 I Donated Share Posted December 20, 2010 and what is the plastic piece in the very last picture its the kanooter valve -broknindarkagain My Current Project - Click Here COME AND TAKE IT "The only thing necessary for the triumph of evil is for good men to do nothing."

Yamarocket630 Posted December 25, 2010 Share Posted December 25, 2010 That head is wasted. You could try to use it, but it will likely give you major problems. Link to comment Share on other sites More sharing options...
Platinum_Racing Posted December 30, 2010 Share Posted December 30, 2010 ^^^ +1 You could fix it but it's lost some integrity for sure. Honestly I would just try and find another head with cams. If that doesn't work you can just get another cam and use this head. It will probably last a while just as long as the part of the head where the cam bearing bolts to isn't gouged or anything you can still get use out of the head, but I wouldn't be surprised if it was cracked somewhere else as a result of whatever the Hell happened in there. Also, that giant chunk that's missing is just a gigantic weak spot for that head. I see stress fractures in the future of that head. Welding cast aluminum is possible, but for a high stress application like this it's unlikely to hold forever. Your best bet might be to just machine some of the broken crap off of the head with a Bridgeport (Machine shops will have the right machines) and just running it till the head dies. Either you replace the head now or you replace it later, but you will have to replace that head eventually. Link to comment Share on other sites More sharing options...
Platinum_Racing Posted December 30, 2010 Share Posted December 30, 2010 Oh yeah, and don't even think of using that cam.... Its totally wasted. Link to comment Share on other sites More sharing options...
SBT Posted December 30, 2010 Share Posted December 30, 2010 That head is done IMO. And you can't use the TT setup on USDM models, due to the LHD setup with all of the brake booster, clutch master cylinder, and steering shaft blocking that turbo. And that plastic piece is the PCV on the EJ205 (and EJ255/257 for that matter). - Pro amore Dei et patriam et populum - Link to comment Share on other sites More sharing options...

The only thing that happened is the guy who took the cams out lifted the cam from the other side at an angle and busted that . Link to comment Share on other sites More sharing options...
ehsnils Posted January 1, 2011 Share Posted January 1, 2011 It's a support/axial bearing surface to control the axial play, and if the surface is damaged it may grind away metal from the cylinder head. Link to comment Share on other sites More sharing options...
brittcrowell Posted January 5, 2011 Share Posted January 5, 2011 Just use some JB weld on it. That will work! We use it all the time here in Alabama. I even use it on my A8 Audi. Bammer Link to comment Share on other sites More sharing options...
