My first post.. anyone ever done 98 engine and trans on 97 down?
I was wondering if anyone ever fitted the 1uzfe 290HP with the 5speed tranny on the 95 year lexus in my case...
I am thinking on doing this conversion some day as the 5 speed is great. I might end up putting an LS6 (GM) engine in there with 450HP with heads and headers using stock cam to keep the car quiet.
BUt a 290HP 5speed should be direct fit.. only change computer and harnessess should bolt right in???
Anyone ever done it?

I was talking about this same swap with Todd a few weeks back, doable. He has a V-8 and tranny from a '98 GS and since that project got pulled, I was tempted to learn what this may do for the older LS's. Just have to find the engine, tranny and harness and get into it.
Given the $$ to performance ratio, there are other avenues to pursue for a lower cost. Port polish, headers, forged pistons, stroked... This project insterests me but it is doubtful I'd do such a thing to mine.
A guy on the Cressida forum came across one Cressida owner who dropped in an LS1 into his MX62 80-84 Cressida.

You had stated a VVTi and tranny swap...okay. I'm commenting that for the cost, working over the non-VVTi will yield some very good gains for the 95-97. If you are asking which tranny is the nicer component, the 5SPD.
For a stock swap 98 VVTi and tranny to a equal cost built non-VVTi with 4spd, I feel the ratio goes toward the 95-97. IMO. YMMV
The headers would be a one-off project that you'd have to approach a competent shop to build.

at what cost
at what cost?
the 98 ECU is probably a G.
and the 5-speed tranny is most likely from a wrecked LS,
still expensive though.
I'm still thinking about the $$ to HP ratio.
Someone tell me why a 5spd auto is better than the standard four?
Lo

The 1997 GS 300 used the 1998 5 speed found in the next gen GS/LS/SC 400s. So the older cars should be able to use the tranny with no problem.
As you stated, its mostly computer adjustments.
