the only national race car that had a 1j in it now has a 13b turbo, was running from 22psi to 29psi of boost with a standard bottom end. this lasted for a full season like this{grabbed a piston.} until they bolted another import bottom end in it overnight at a race meeting. anything under 20psi would be fine. as long as its kept cool and has plenty of oil. long term keep it at 18 psi and it will be fine. they got about 650hp out of it with 26 psi. this was with two t3 and a motec etc. make sure it uses a big oil cooler. mick
