V8 swap beginner questions

[natony]

I'm really interested in doing a V8 swap on a rolling shell i have, i'm perfectly fine when it comes to the mechanicals but could really use some advice.

I've looked all over the net and found that quite a few people have done the swap but no-one every did a detailed build thread.

 

I'm planning on going with a later 1uz vvti and want to use a r154 gearbox as i may turbo it in the future

 

My main questions are:

With regards to mounting the r154, i've found spacers, custom bell housings, thicker flywheels ect. which is the most straight forward ?

 

Which clutch do i use ?

 

How does the exhaust work ? the v8 has manifolds both sides so how is it made to work on a supra ?

 

Thanks for any help, i may have more questions as thing progress

Contact msmile who is a member on here, he has just done a v8 conversion

Headers go down into a custom Y pipe under the car and join a supra TT exhaust. That's how mine works with long headers. Vvti and pre vvti can share headers from an ls400 or soarer if using stock.

 

If you don't have all the immobiliser parts from the ls400 vvti you'll need to do a security bypass if keeping the Lexus ecu. Msmile is using a w58, I'm using a TT auto so he'll know more about your clutch.

Bear in mind that the later UZs (from 1994?) have weaker connecting rods.

 

As far as the exhaust is concerned, the reason it's such an easy(ish) swap is that the Supra used the Soarer chassis and crossmember, and the Soarer was fitted with the V8 (so you need a Soarer sump, not LS/GS).
