Hey man I'm not that much further on tbh I bought an st170 winter / parts cars and its mot isn't up till April so I'm just gonna run it till then.
I'm also planning on running the ME ecu and loom but im just gonna do the engine swap atm to save some ££ maybe a turbo in a few years once the body has been painted 😳
I'm also gonna run the standard ib5 till it breaks also the cheapest and easiest way. So apart from the mount at the engine side you dont really have to do any modifications. And I've heard the st170 engine fit two of the three bolts for that mount so I was just gonna fit it up the see from there how to make the last bolt work
Hope that helps dude
