I was looking for some feedback and comments on the engine rebuild I'm planning. Its been a while since I posted anything, sorry to be a stranger.
Here's the Low Down.
I did a little damage to my t16. Leaned out #1 and melted some of the pistion, but what did the piston in was a huge crack in the grove for the oil scraper rings,that also split a ring land in half. Cylinder #2 has some deep ass scours in the wall, can you say BLOW BY. COmp test before Diss was #1 50psi #2 135psi, #3,#4 185-190. Still went like hell.
Upon inspection theres no way I'm going to able to use my block unless I bore the shit out of it. All other non wear parts are in fine shape.
There's no way in hell i'm going to pay $100 a piece for a stock replacment piston w/rings. 9.0 comp. I can get some Forged pistons for the same price. Or some Hyper's probly the best choice and w/ a 8.5comp ratio.
To save some money I could get some slugs for $15.50 EACH. yES THATS WHAT i SAID. I stumbled across a shop that has early 8Valve turbo pistons W/rings for this unbelievable price. They are 7.2 comp. ratio, and I have to get 1.00mm 2nd oversize slugs only. Standard AB bore pistons are $100.
So here's what I think I will do. For less the a set of new rings, I'll get a set of pistons w/rings. New bearings,thrusts washers, gaskets and seals,timing chain, etc. Have block bored out .040" over. Balance rods,possible polish and piston squirters. Now I was going to go with a fresh ported 2.1 head, but have been thinking about scouring some yards for a t-5 head, and do a little timing cover fab. To compensate for the low comp ratio I'll just turn up the boost. For the fueling problems megasquirt me, and my new secret weapon,Velocity Stacks.
I guess this combo should get me rolling again,comment's.
Go Swift,
Go Safe,
Go Saab
