Hi,
I am wondering whether a VK EFI motor will fit in the engine bay of an LC GTR Torana. I have seen them on Ebay, with computer and wiring loom, extractors, etc, and they would give me good performance and economy.

The induction parts (Whatever they are called!) appear to be high, so I wonder whether the bonnet would close. Currently the Torana has a red 6 with extractors, and there is very little room to get the exhaust past the front cross member and sway bar.

I am also thinking of fitting a Supra gearbox (I am still using the original Opel gearbox. I can't complain about it - it has done 260 000 miles). I will use a W55 box. I don't want to cut another hole in the floor, so which box do I need to use?

You will need to fit WB blue motor extractors.

Thanks for your help fellas. I won't put a hole in the bonnet to fit a VK motor, so that option is out. I will either modify a 186 or look at other options like those suggested by Brian.

The 186 motor might be a primitive gas guzzler, but it is in keep

Keeping it simple has its advantages

You could use the 186, but being bored to 192 it is already at +0.060 bore, and I wouldn't advise trying to go any further, assuming you could even buy 186 +0.080" pistons. If it's in OK nick though, use it as is.
Personally, I'd go the 202 with a blue c

You could use a blue or black bottom end but then you run into ADR pollution requirements. The blue crank and rods fit straight into a red block (with rope seal), and then it is basically the same thing. Blue/black blocks are no stronger than a red one. Y

Thanks again Byron.

What is the advantage of a blue crank and rods over red crank and rods?

I was intending to use a Commodore electronic distributor. Is that what you means by HEI distributor?

I assume jetting up the carby means fitting bigger j

Thanks Brian.

I'm learning a lot from what you and Byron have said. I'll continue reading for a while so I have a better idea of the options before I do anything.

Fuel economy is an issue, but one thing about the old motors is that they are fairly r

Black crank and rods are the same as blue, except for a locating dowel for the flywheel which can easily be removed.
