I should have the supra back from the paint shop the end of the week. i got a hell of a deal on a turbo manifold and a 61mm trim turbo, elbow, etc... just need a down pipe. is there a water plate on the block for the turbo or do i need to tap in somewhere?? i guess the main question is, are the blocks identical?

you mean are the blocks between turbo and N/A identical? no, they're not. its the same basic casting, but they're not the same. you cant just slap on a turbo manifold, and a turbo and call it a day.

Oil supply is fairly easy the Oil drain/return is a bitch to do on an NA block so most people weld a bung in the pan.

Coolant can be done with simple T's into the heater hoses.

hmm, I always read that the oil squirters are a fairly important part in converting an NA to turbo... interesting.

Colin: My take on squirters is they're a huge pressure leak and just move heat into the oil.

I've ran quite a few na/t type motors over the years without squirters with no issue, but I always make sure the cooling system is as good as I can make it.(both oil and water)
