Factory IS400 ?

Retrofit UCF10 into an IS, never factory produced.

How hard would it be to do this mod? Seen a few other IS200s with this V8 in and all looks very tempting? :)

If u cant do the swap urself then Thor Racing are experienced doing this sort of thing but will set u back 4.5-5.5k, which is the figure I was given recently as I was curious ;-)

I was the development engineer at thor, till made redundant 3 years ago. I designed and made all the elements relative to these V8 conversions in the Supra's and IS200. If anyone is interested in this type of thing then they should contact me in person to discuss their requirements.

Blimey,

I assume the suspension/powertrain mods would be significant, I understand (not tested) that the simple throttle mod on the 300 that is popular in the US, makes it very difficult to put the power down with the standard 300 engine!
