well heres how it all started i was coming home one day from a friends house and then i see the audi tt coming up behind me and pulls up beside me and revs up... so i was like ok.. im only pushing 14 psi but i ran him any way. well i pulled on him when i down shifted to 3 and then all of a sudden something pops in the engine bay and it starts to bog down, i checked for a CEL but none... so then he comes zooming past me and i drove home with it bogging on me... come to find out my coil cracked in half (i'll post the pic up when i can get a camera) so since driving home from my friends house with it bogging on me for a while i burned up the pistons and piston rings on the car... now im debating on weather to go 1.5jz or just go 2jz... just want to know how the 1j head reacts to the 2j block or how much better or worse a 2jz swap is, and whats you guys look on it... thanks
