Very nice work. Clean swap. Do you have to fabricate new cross member or used the old ones?

not sure what the OP did but james he should be able to keep the stock crossmember since he used a front sump chaser 1JZ. i BELIEVE (iirc) that Mounts from a SC300 or later vvti SC/GS300 should let him bolt the JZ series into his car easily.

what pure drifter said i didnt have to do any modification to the car at all the transmission bolted up to the stock location then i used the chaser mounts that came withthe 1jz and the stock rubbers the passenger side lined up great i had to make a little extension about 2 inchs on driverside it save me some money instead of trying to find the aristo mounts ill get more pictures of the swap and i have a video on youtube of the first startup it kinda sucks but it shows it running look for 1jz ls400

Those are some long sentences. The swap is sick, need more build pictures if their around... What's your plan for exhaust single or dual exhaust?

well i took it for the first test drive today it runs like crap i doesnt shift out of first gear and it acts like it is hitting like a launch control when free reving and when i drive it and give it more than 20% throttle it acts the same way the turbo starts spooling but it feels like it is just stalling any ideas?

you screwed up the wiring, the timing, or something else controlling the motor...
