Re: What to expect from a built motor
Given that OT and YT have both been running 8 - 12 psi with the stock pistons/rings/block for a while, I would hope that you could safely go to 15-20 with a built motor (assuming you've got a good tune, of course!)

Do you think the STOCK EG33 sleeves can hold that much? Check Tom00799

Re: What to expect from a built motor
Has anyone ever found links to the EG33 drag Impreza builds? There are more than a handful of them running in the 1300+hp region. I'd assume one would have to go through the same build, other than removing water jackets to add to the intake or any of that crazy nonsense those drag people do.

Re: What to expect from a built motor
When I said at least twice 8-10 I was meaning to say "at least 16", sorry for the confusing. 20 to 25 lbs sounds good to me, it all depends I guess. I can bolt a turbo to it that can do it, the whole thread was mainly can the build motor stomach it and can I tune it though lol

Re: What to expect from a built motor
If it makes you feel any better, I've put about 20K miles on mine while running 8lbs of boost, with the supercharger setup that Mike at ECUTune put together.

The fuse trick only works for the US auto transmission because you can switch off the rear solenoid, which punts all the motive power to the front differential. Once you have a 5-speed fitted that fuse will do nada. Quote:
Whipple powered EG33 charts Have a browse through these charts if you want to assess potential numbers. This spreadsheet essentially treats the EG33 motor as a pump that develops hp based on the amount of oxygen pushed through by forced induction. To achieve these figures you would need to have your tuning right or the numbers achieved will be lower. They are net figures at the crank, not WHP. Also you will notice if you compare the charts that the figures won't give you the desired hp without charge cooling. In the charts where charge cooling is at zero temperatures are up, often beyond safe limits. High in-cylinder temperatures mean less oxygen ingested and higher risk of pre-detonation and melting pistons. A lose-lose scenario. Anything that has been done with an EJ 4 cylinder engine can more or less be done with the EG 33 six cylinder, which is essentially an EJ4 + 2. So in theory any builder-tuner that has done EJ engines can do the same for you with our flat six. I'm agreeing with the thrust of the advice given to you so far. As you are putting money into an engine build there is no point in your boosting to the 8-10 lbs we know the standard engine is safe for. Most factory tuned EJ engines operate at around 1 ATM or 15 lbs, so a built engine with good charge cooling and tuning should be safe for this level. Going much beyond this you are into more risky territory, so I would suggest your engine design parameters should be to hold a safe 20 lbs, and that would probably include new liners and semi closing the deck. Joe BTW, before you order the pistons tomorrow, if you really want to go for bigger numbers, should you not be doing what RallyRob did and use larger pistons for a bigger swept volume?

Re: What to expect from a built motor
Doh.. You are correct. I'm not sure what made me thing the fuse would still work on the manual trans. Never put 2 and 2 together on that one
Main reason for not going bigger is I am not a fabricator nor do I have good access to a shop I'd trust to do it and honing or anything. Also, I'm buying my pistons used so theyre already made |
