Hi guys looking into putting a 308 Into my ms55, just wondering if anyone on here has done the same conversion

i guy i worked with a few yearsback had one with a worked 202 holden motor, the bl00dy thing was off the hook, but handled like a boat.good luck with whatever ya do.

Hey Michael...yeah it can be done...it's been done before...but it's a hell of a lot easier to put a supra 7mgte turbo engine into it (173kW)....bolts straight in on the toyota engine mounts...i had one for a few years. and i know a V8 sounds nice....but the look i used to get from ss commodore drivers when my 1969 MS-55 blew them to the weeds was priceless. I used a toyota 4 speed auto with the lock-up converter. You could also try the later supra 1jzge or 2jzge motors (2.5 and 3.0 litre 6 cylinder). both of which have twin turbo variants....there will be clearance issues with the twin turbo set up around the steering box but earlier crown engine mounts will bolt up to them. You could also try the toyota 1uz (4 litre quad cam alloy V8)...the bonus with using the toyota engines comes with the transmission fit-up...or simply bolt up options without transmission tunnel modifications.
If you want any more info about this model crown, i'm more than hapy to talk with ya mate.
cheers stru.
