Yeah, but I have no baseline to compare the "cleaning" to. I WILL say the lowend torque is...well... And one thing I found with the porting...it removes material that is in the way of the injector spray, meaning the spray is no longer destroyed before it hits the valve, and *should* cut down on carbon build-up.

I *do* recommend polishing up the valves if new ones are not going to be included. Also recommend new lifters since it will be open anyways.

And I should have done this during the motor building idle season....get your injectors cleaned and matched.

lets keep this realistic, i have ALMOST ruled ot an S2 swap because it may be more then me and my mechanic are willing to take on. (but its not 100% ruled out so if you guys have GOOD arguments on this lets hear it. Boosty? Randy? Bill? anyone)

If anybody has any ideas feel free to tell me, links to different thing are always welcome because i want to take this all as a learning experiance and i want to read up on what ever i can to get a good balance or Performance/reliability (maybe leaning just a tad closer to the Performance side of the equation )

Well, I'd say you better get yourself an engine stand. :P

Pull the engine apart and do an assessment. Your time will be cheaper than having a shop to it.........and we can all help you along the way.

$2000 means doing it yourself.

Personally, I would try and find a good used engine first and swap it in. Then pull the old one apart just for the learning experience....or use it as a trade in.

ok, well lets lok more at the performance aspect of what i can do During the rebuilding stage (atleast in this thread)

so far from this thread ive got ideas that include:
94-95 L67 heads
P/P current */C & LIM (mild only)
PEMS
maybe a cam, but i know nothing about cam work ( i from some stuff i have read i dont know if *.O.P. would be the best place to go for that) -correct me if im wrong

keep it coming guys!

correct....keep in mind that Comp Cams will build you a cam to YOUR specs for the same price or cheaper than Series One Performance...

also if you dont want to cam it and are getting the 94/95 heads 1.8 rockers might be a good option for you also

You could easily do a S2 swap in there for under $1500. $2k if you do a good drop out with trans. The wiring is actually pretty straight foward, and if you got a drop out you wouldn't need much PCM work. And future modding would be SO much easier...

Was thinking the same thing. Nothing against series one guys, but why spend $2k on fixing that one when you can swap in a series II with trans for that price. The wiring is simple like Jermiah said, just need the diagram for the engine harness and the diagram for the cars harness, then just cut and splice, not complicated just a little time consuming.

But, on that note, you could probably get a used Series I for WAY less than that and put that in. Thats probably what I would do is just a used stock replacement...
