its got about 200miles on it allready and i found my first problem. i am not 100% sure i have this right but i think i do. today i got on it a little from a light. maybe 5psi. i pulled into a parking lot right after that and there was a **** load of oil pooring out of the tq converter area. i looked at the oil lines and all other posiable sources and it is definately coming from the tq converter area. not sure what happened i goto lunch and when i come back i top off the oil(1quart) and fire it back up. no leaks at all..... the thing **** out a quart of oil past the rear main and then didn't leak at all after that?
i tried something with my crank case evac and i think it isn't good enough. i think i got crank case presure and it pushed the oil right out. here is a pic of the exhaust evac set up i have. there are no other vents.
there is strong vacume on this port at idle but i dont know how much when i get on it. i am going to leave this on and just put a filter/vent in someplace and see how that works.

hmmm.... looks like im gonna have to go bigger!
Nice, great stuff!! Your old numbers, 1000rwhp+, at 22psi, thats with the pt88, what kind of gas were you running with that?
Here is something, most ppl ask about the regular turbo stuff that make up a turbo kit, but what about the other odds and ends? I read a evac... what else you recommend to get a similar setup up hassle free?
Also, you mentioned that the new setup felt a bit laggy, is that compared to your old pt88? ALso, those are the port shrouded 70's, with the .81 a/r... doesn't that port cause a bit of "boost leak", making it feel more laggy? (newbie question alert!!)

i dont know if it is laggy or not yet but it seems like it will be. i haven't brake stalled it and then mashed the throttle yet. right now i would say it is about the same as the 88 wich in my book will be ok since there is an extra 500hp on tap. i dont know what you are talking about on the port shrouded thing.

Are these the turbos you are running? If so, these are the gtsh 70'z, port shroud'd turbos..... they have a small port to help the turbo stay out of the surge line before peak boost is obtained..
