I got a 87 Daytona shelbyz turbo 2. 2.2 2pc intake. I'm running 72# injectors,3 bar map, boostbutton cal 18# of boost 21# shutoff. My clutch was slipping when I got over 14# of boost so I ordered a cluch kit it's probably a factor original clutch in the car with 105k miles. anyways I've been monitoring my oil pressure with sunpro gauges and it is great when cold but gets very low at idle when hot. so I bought a oil pump. I have other goodies, I was going to install when I do the clutch, ss oil lines, and new coolant lines,new alternater, new water pump. Well anyways was driving it a little hard today and it stalled. restarted it and it has no power and it's rapping! I did a compression test I got 90 120 120 60 I know the 60 and 90 is horrable don't know if its rings or what yet. I know where I can get a good 89 2.5 block for dirt cheap. I'm off of work rite now money is super tight or I would buy a set of forged pistons and do a full rebuild. Is there a good factory block I can just put my top end on?? if so what year? is there any cheap upgrades I can do to the motor when I have it apart?? Just looking for some good advice what would you guys would do??? the head was a remanufactured unit I put in last summer. Or if anyone has a good block I can get for cheap within 2 hours of 16125 it would be greatly appreciated! I really wont know what damage I did till I get it apart, but I think I heard that 87 t2 had just a normal t1 block. I'm not looking to build a race car rite now just something that will be loads of fun to drive, and smoke most Camaros! I also had a lot of pcv issues I tried several different ways. I put a 5/8 nipple between cone filter and turbo and have a tbi valve cover with oil skirt, drives side nipple on valve cover routed o nipple on air filter line. passenger side nipple with a elbow with pcv valve to large nipple at rear of intake. The cyclinder walls looked great with the head offlast summer and I had 120psi across the board after head gasket last summer. is thred anything I should look at first when I pull motor? I may have bee exirencing blow by the wholetime since ive had it but when the compression was 120 I cantundersand why I would have blowby? I routed vacuum lines according to digram under hood with check valves ad orifaces. I forgot to mention im running straight pipe exhaust even ran the pie through the glasspack! running 93 can gas. after restarting I only had to go 1.5 miles. hoping I didn't do to much inner damage? any sugestions would be great hoping I can just put new rings and bearings in? but wont know till I get motor apart? I can get a re-ring kit for 115 shipped- same vender I got the rebuild kit for my old 300 straight 6 last spring.
thanks
