My Hybrid ran for 20 min. pics

Since it's been so long since i'v been on here i'll give a quick refresher on my setup.

BOTTOM END-2.2 forged crank,Eagle Hbeams, Venolia pistons=Junk more on that later. balanced
HEAD-stock 95 2.0, stock cams, FWD adjustable gears
EXHAUST-custom ShearerFab manifold, T-61, Tial 44, 3"
ELECTRONICS-1990 DSM turbo wiring harness and ECU, SAFC, GM 3" blow through MAF, with MAF translator
MISC-880 injectors, modified 2.0 intake, 24"x 8" up/down flow intercooler, DSM throttle body, Walbro 255

Well I did get it running so my biggest ? about the whole project was answered: can I run any 4 cyl off the dsm wiring? It was very easy. Once the harness was stripped of all the unneccessary junk wiring it to the motor was straightforward. The only challenge was the cam angle sensor. I had to make an adapter plate and then just cut a slot in the end of the cam to accept the tabs on the CAS. Under the dash all I had left to do was power up the ECU which was 3 hots and a ground. The MAF translator for the GM MAF was a direct plug in made for 1st gen DSM's (the GM MAF and translator are optional if you want to run a stock MAF or run a 2nd gen DSM MAF which is only good up to about 400whp)
I ran the rest of the car off an 84 carb car harness since it it is much simpler than the 2 module turbo harness. I used it to run the lights, starter, charging sytem (with 84 external voltage regulator) and wipers. I was able to get rid of the underhood computer completely (spark control computer I think it was called on the carb cars)
So anyway. it ran, I drove it around the block, and it smoked out the whole street and rattled like a diesel. Bottom end is out and being sent back to the builder.

That sucks I hate having to do things twice, I think this would be the first time ive ever heard anything bad about venolia pistons they run them in top fuel dragsters and funny cars so you know there tough

[crusty shadow]

i doubt there was anything wrong with the pistons, sounds like machinist was a crack head

[crazymadbastard]

Congrats on getting it running! very potent combo and unique idea about running dsm electronics, too bad about the crack-head machinist.

why are venolias junk?

I don't want to say too much till I know exactly what went wrong and who to blame. But first of all the piston skirts were not all the same size. I wish I had measured them myself when I got them and not assumed the machinist would have taken the time to do so. secondly the machinist apparently only measured one and assumed they were all the same and I suspect the cylanders were over bored too. They had a piston to wall clearance of #1.0120, #2.0075, #3.0075, #4.0090.

BTW: Since the Venolias are just T3 pistons that happen to work with the neon head I'm having 3 sets of Wisecos custom made specifically for the hybrid combo. I'm using one set, keeping one set and selling the third.The third set was spoken for but he backed out so PM me for details if interested. Once I get them I will post the part # if anybody wants a set.

Congratulations on getting it running!!!.

Oh... Time for a name change.

Nice to hear you are back in action Mike. Hope you get your engine figure out in time to make a few passes, this year.

I should have the new block back by next week. Once the shortlock is assembled It should only take a day or 2 to get it running. I hope to have it at the Norwalk Mopar event in Sept.
