checking out an 86 mk3 tomorrow

[MA70-3.0GT]

Tell you what then, seeing as you're getting this block all sorted & you've tipped money into it already then how does this sound?

Pick up a complete turbo car that's either been wrapped round a tree etc, or got a rod through it's belly but good blower, hopefully good head & all the electronics & other bits you need to convert to GTE spec?

Then get your man at the shop to drill the oil drain & flush the block as per cre, and instead of buying N/A pistons for whatever oversize the bores are at, just get Turbo ones.

That way you get a good as new (better than new bearing in mind overbore) block & all the kit you need to make a real GTE motor... Plus you'll have a certain amount of other spares from the wreck which you can either swap to your car if better, or sell off to make some of your outlay back.
