Hello all I'm Joni have a mk1 gs300 I am at present stripping it down for a respray in and out but will eventually upgrade the engine to a manual twin turbo engine from a supra and was wanting advice to see if it will fit straight in or be a pain thankyou all for reading

It fits, Toyota sold it in Japan with that engine, but any engine swap is a pain. Intake, exhaust, ECU, gearbox are not going to just bolt on.

Thankyou Colin I know it will take some work to get it all put together and running to perfection I have all the time in the world I'm just worried about the engine mounts really not really wanting to mess with that bit

A manual GS would be cool to have B)

Manual supra boxes are expensive from what I can gather, lots of folk after them. Not sure what the output of the manual box is like either, you may need to fabricate a prop shaft. As the GS was never a manual, you may have some fabrication to so to get a pedal box up and running. Engine mounts shouldn't be an issue.

One of those jobs that would be much easier to start with the Aristo and already have the twin turbo install sorted, just leaving the manual conversion to do.

A manual Supra box is strong, a friend of mine has a 600bhp single turbo set up in his UK manual Supra, he's uprated the clutch but the box is standard. If you can find one I'd buy a complete manual Supra perhaps accident damaged, that way you have pretty much everything you need.

I never particularly liked the Supra TT clutch/manual gearbox, to me it was the worst part of the vehicle - and not just because it was German ;) . Saying that the 4 speed auto isn't that great, personally I would use one of the newer 5 speed autos from the series II Aristo TT.

With regards to the engine mounts, on the Supra they are in the same position for the NA and TT. I'd therefore assume the GS300 uses the same positions and so a Supra engine will drop in fine, or at least the mountings could be removed from your old NA engine and used on the TT engine if they are differences between the GS and Supra.

Not sure if the GS engine mounts are just solid rubber. The Supra TT mounts were fluid filled and were prone to leak when aged.

Thankyou all Im glad the mounts should be the same place :) this makes me happy lol know I could buy a aristo but I rescued the car from someone's garden and is now my one and only project and for some reason I have to do this thankyou for your help will keep you all updated
