206HP/296NM probably too much for 7AFTE - 6G Celicas Forums

Topic #66889 9 posts Started by malpaso
Folks, sad to say that but after 2 years of running 7AFTE (by doGGy) on 0.5 - 0.9 bar it seems engine is doing down kindasad.gif. True is for last 10month I have been running 0.9 only (because 0.6 was too low for me biggrin.gif). Now I must face consequences kindasad.gif. Seems that stock internals are not able to hold that pressure. During compression measurement last weekend I found oil in combustion chamber #1. Also compression ratio is more various than should be for each valve (should be 9.5 for all and is between 8.5 to 10.5) so it seems engine needs to be rebuild kindasad.gif. In few days (hopefully) I will have plans and funds ready for this rebuild... My aim is having safe 7AFTE. That means to not destroy engine in two years again... I want power and 0.5 bar (176HP/225NM) is really not enough for me now as power for common driving.

note: according facts above my car will not participate PECM2009 in Greece frown.gif. That' the worst that could happen for me...

Dang, sorry to hear that. Malpaso, you met Tufy, with that 2.2L stroker kit, did you know if he daily driven that car? I have been asking around but couldn't get much information. I know it is rather off the topic, but just curious.

I hope everything goes well for you and I am sure you can even rebuild the engine better than it was before. I want to rebuild mine just so I have a Toyota engine to build, but I need to get another car first.

Just out of curiosity what tranny were you using with that setup, the stock c52?

Sorry to hear about the engine, but you can always do it better, faster stronger!

Hi martin. sorry to hear about this. but this was how i started my engine build. good luck with rebuild.
About my stroker.. you can drive it daily like a stock engine. the matter is what boost you will have with daily drive.

Thanks guys... engine is still running and it would run just fine after small repair (rings, seals and stuff) and of course if I push it less (lower boost for 20%). But that is what I do not want... I do not want silly 180HP smile.gifwink.gif. That's why I will rebuild it completely and push bit higher. Only I wish I had source for complete 2.0L stroker kit for 7AFE... I can't find anyone who sells that frown.gif.

note: yes I still have been using stock 7AFE tranny (even stock axles) and it works fine... no troubles at all
