68BAJA Posted April 21, 2015 Share Posted April 21, 2015 I got a 91 subaru 2.2 for a swap into a bug and it has grey trey top injectors on the passenger side and red top injectors on the driver side do the red top flow more? I Sence there on the 2.5 motors i plan on turboing my 2.2 so the extra fuel will be good ive done a lot of research already people say it runs rich witch is good if i turbo it but is that true? All the forms i have seen are old is there any more info on this? And what year red tops fit? The 91 2.2? Link to comment Share on other sites More sharing options...

I replaced the air bleed, with a valve that bleeds off back into my intake, and I can make very minute adjustments of my a/f ratio. I tried the ebay junk, I wont even sell it to someone else its that bad Link to comment Share on other sites More sharing options...

Yes I turboed my 2.2, I'm not 100% sure if the rails will fit, everything I read they will with the spacers. but havent tried, still running the na rails with the redtops Link to comment Share on other sites More sharing options...

bcmaxx Posted April 23, 2015 Share Posted April 23, 2015 the 2.2e engine made it about 6000km @16psi on td04, I think it would have lived a long life at a reasonable boost pressure for the high compression.(ringland failure) swapped in a ej22t,vf39 @ 18-20psi with water injection, 12,000km and running strong. I have 3" sti turbo back, but its overkill I think Link to comment Share on other sites More sharing options...

USLiberty Posted April 24, 2015 Share Posted April 24, 2015 Nice on the swap! Been thinking of doing a super sleeper VW myself. I think the sidefeed 550cc 04 STI along with the legacy gt injectors will go in the early ej22e fuel rails. I am planning on using those early fuel rails to install some larger injectors from a turbo LGT. I also have an EJ20t intake with rails and injectors. Soon, I will be making a for sale ad with lots of phase 1 parts. Link to comment Share on other sites More sharing options...

USLiberty Posted April 26, 2015 Share Posted April 26, 2015 Yeah the transaxle is the weak link. I wouldn't spend too much money on upgrading the motor, you can get a low mileage ej20g for about 1000$ capable of 280HP with just a tune, exhaust. Some even come with harness and ecu.
