1990 supra rod knock

[toyotaguy4x4]

I have a 90 supra turbo with some slight rod knock I am looking to rebuild the engine. I am just wanting to put it back stock but with some better parts nothing to expensivei just want it to hold up better than what it did from the factory. Can anyone tell me what brand gasket sets and what brand and type of head gasket and bearings to use along with a good quality pistons without breaking the bank. It will be stock boost with no fancy parts on the car

Oem gaskets can be had from any toyata dealer..
Eagle rods are bullet proof. don't know the price but thats pretty much what everyone uses.

the eagle rods are no cheap and neither are good pistons.

How much power are the stock rods and pistons capable of safely handling and how much boost

It's a 20 year old engine... are you asking about the original, antique hardware or about new, OEM hardware? Old... take a guess and pray it's close. New... Well, there's someone on SM who built a completely OEM longblock just to see how much it would take before exploding... he's up to some just under 800RWHP or something crazy like that the last I saw. He has a LOT of other stuff in his build though to support it. It should die an amazing and spectacular death any day now. He'll probably even get a cool "danger to manifold" message. And no, it's not a daily driver or anything from what I recall.



I think the pistons are the weakest part of the equation. I would get an OEM set of rods balanced, shot peened and cryo'd and then get some good forged pistons.

On a bone stock, old hardware, setup you could try 10 or so. You'll hit fuel cut between 12 and 14, anyway. If there's any problem in your fuel system this is a neat way to find out.
