Converting a GS300 to GS400S

[frost_kamikaze]

Hey all, I'm wanting to convert my gen 2 GS300 to a GS400 supercharged. Anybody know if this entails anything other than the engine swap? Cheers guys.

Ummm yeah, a lot more.

 

[frost_kamikaze]

any idea about the specifics?

Based on the amount of research you have done---dont bother thinking about it.

Chances are----if anything on the SS300 is different from a 400 you will likely have to change it....that is just a start. Forced induction is a different story all together.

When I say if anything is different, I am reffering to the engine/drive/engine management system.

Searching is boring and tedious but you gotta do it.

Ok, but i'm talking more about what i wouldn't upgrade anyway to boost it up to 500bhp. Keeping in mind that the gearbox is the same.

To be 100% honest, step one would be to sell your car, and find a GS400,
it's easier and cheaper. It takes out a lot of guess work too.

She's not going to be an easy swap.
Toyota changed a lot of electrical things around that era, which makes swaps much much harder for the home person.
Physically the swap would be piss easy.
Getting everything to work as per factory could easily end up a nightmare.

Search on here for the fella who did the swap into his IS200 sports wagon. I'd say you'd be up for similar challenges.

I too reckon you'd be much better off to sell the GS300 and buy a GS400.
However due to the severe lack of GS400's in Australia, I'd say look into an LS400 as your base car.

There is however an AWD GS400/Aristo for sale on autotrader.com.au - I reckon that would be worth a good looking at.

Cheers peewee, i checked out those gen1 aristo's on autotrader. Problem is I like my gen2 shape. Which brings me to another problem, even if I were to sell it to get a gen2 gs400, where do I find a gen2 gs400 with the auz drivers side? i've never seen them
