absolutely NOT...

completely different engines and electronics.....

you can try to get custom manifolds made, remember its a V6, so you would likely want to do a TWIN TURBO set up on an IS250

You can use the turbo,wastegate and cooler depending on size for fitment to the front of the new car..

Single turbo kits on V engines work just fine, We have made plenty single LS1 kits that fly. A little more thought put into the manifolds but its a can do.. The cooler side of things are also easier for piping with the single kit unless you go vertical core (not a good idea for efficency reasons in that car) hight..


Good luck with your new car and plans

the new gen IS motors are VERY high compression motors & will be VERY tricky to boost properly & Stay safe( IE: intact) .... it will be VERY easy to overboost & blow the motor unless you go thru the expense of reducing compression some how Herad gaskets .. .etc ... I assume it wil lcost GRIOP o cash to pullthat motor & pul the heads off to reduce compression

i hear those motors are like 15k fro mLexus also if you need t o replace one...

Good luck!!!

keep us posted

Just get a manual is250 and swap in a 6spd 2jz. Well atleast that's what I'm gonna be doing

Third time around
2002 6spd IS300 w/ a whole lot of goodies

573whp and 510tq @ 19psi 93 pump
805whp and 695tq @ 32psi meth mix

*10.67 @ 144mph 1.66 60' on ET street drag radials
*11.33 @ 137mph 2.1 60' on street radials

Sold. No more boost for me. I'm done

Yea but the kit probably cost more than the 2jz motor. Besides, the 2jz is easy to work with.
