10psi. After that the inlet temps rise too much and kill any benefits of increasing the boost and so this levels the power out. Fit an intercooler and then you can winde this up by an extra 4psi with a very healthy standard Turbo.

Is there a fuel pump available of another car which can be used instead of a wahlbro? ie a skyline one or something?

ive heard of people using a 300zx pump, it should do the job as they are 280bhp as std and i bet you can tune them a bit before you have to change the pump.

Here's a quick one for anyone who's listening. When fitting a T25 do you re-use the old oil feed line or do you have to get a double banjo ended braided hose made up?

if you go on fj20.com, it will tell you what part you will need to stop chain rattle,its a ratchet tentioner off of an old mazda i think, the part number is on the site.i think if you give wayne at chipwizards a ring, then he could put you straight on tuning the n/a fj20, as he used to race one.
