Hey all, IÂ’m new to the forum and havenÂ’t done much digging yet. With that said, IÂ’m looking to build my A20 motor in my 89 Accord LX-i for 15-20 pounds of boost. I know thereÂ’s little aftermarket support for these cars so looking for some support. I know new internals are a must. IÂ’m looking to build this right. Also looking for clear tail lights which I saw might be source-able. Any and all help is appreciated!!

This link is in the performance section.
I think 15 lbs of boost you may have head gasket problems but do you research.

89T is running like 30, that's way too high for street and it will still push out the head gasket, but I think head studs are all you need for 20psi. Arp 218-4703
As for the rods and pistons... good luck, unless you start putting B series parts in it. https://www.3geez.com/forum/showthread.php/148427-A20-details-and-B20-rods-pistons-thread
