EG33 swapped Brighton Impreza

Hi everyone! I have been doing alot of reading on this site to gain some more information on the EG33. GREAT INFO!!!! Some of you may have seen the threads on other forums about this car. It a steel widebody Impreza cp I am building for auto-x/light street. As you can imagine, the Impreza community is all about the new EZ30R swaps done by Perrin etc....so not alot of info on the EG. Actually, everyone is asking me why the EG. My main question is, what is available for this engine in N/A config? I have been reading the cam lobe thread so I know there are cams somewhere. Is there one ECU that is better with this engine than others? Who carries them? And to the 5 spd swap guys, how much are you getting your 5 spds to handle torque wise? I have the whole 92 pearl white donor car still (BTW, the car was condemed after an uneducated owner hammered the car....not a good opperating car) I still have alot of good parts left....just ask.) What is the rear end in the SVX? R160? R180? LSD? what ratio?

These pics are @ 45 days ago so much progress has been made since. The build is being documented on www.ultimatecarforum.com a sponsor of our team!

I know I have alot of questions and any help is very much appreciated. Thank you in adance!

I'll get started answering some of your questions...

Rear diff on the SVX is an R160 LSD with 3.55 ratios. This is the same rear end found in the 5spd '02-'05 WRX's (they have a 3.90 front diff and a 1.1:1 step-down to their 3.55 rear diffs)

In terms of engine management - check out www.ecutune.com which is run by a member here who goes by Longassname. You'll probably want to contact him (he lives in Tampa, FL IIRC) to have him develop a custom tune for your car.

Good luck!

Thanks for the start! I'll be snagging the LSD then. I have the 3.90 gears now that match my trans so I guess I'll just change the r&p for now. I may also see if I can use the brakes from the SVX as well (I have factory drum rears now.) Has anyone broken WRX trannys yet?

I have seen a couple of SVX swaps started but no one seems to finish them. I have read somewhere on here that I have to jump a wire so that the rev limiter goes all the way to redline and not stop half way. Is that true if I am not running the t-ecu? I have done a ton of WRX-STi swaps, but this is uncharted for me and finding good info has proven to be the hardest thing.

Thank you again!

Read your thread....you have done a hell of alot of metalwork and custom fabrication so far. seems you just need to get the drivetrain squared away. lemme tell ya, this is a good place to start. Good luck with the project!

Thanks, I have been researching gear ratios and rear end ratios all day...I think I've got it. I have another engine now so I'll just drop that in as stock for now and do a full build on the one pictured. With slicks, I have a feeling I'll end up with a dog 1-2-3 eventually or an STi 6spd.

My biggest question is:

what is available for this engine in N/A config? I have been reading the cam lobe thread so I know there are cams somewhere. Is there one ECU that is better with this engine than others? Who carries them? I will try to contact LAN soon to get his insight, but what about a Megasquirt? I read on here someone is using it. Is that a better way to go than the OE ECU?

Thank you soo much for all of your help!
