So turbo 4k ended up making 178rwhp on around 20psi and loved the boost, head gasket did not love 25psi but :) so was easier to upgrade engine than change head gasket or something like that.
Pulled 4k out about 5 weeks ago and 1jz is nearly ready to run, it's stock motor with a baby 58mm precision turbo, a340 auto, corona struts, rn20 diff with mx83 LSD and gears, microtech, single 044, 1000cc injectors, and 215/60/14 Mickey Thompson radials. Will limit it to 400-450rwhp and should go super reliable 9 second quarters. All on a budget of $5000-6000 including what I payed for the car originally. That's as far as this one will get pushed as it will still be my delivery car for my parts business.
