I've fully cleaned and rebuilt the engine and upgraded to a MD274 cam whilst in bits. The head is currently back at Specialist Conponents having the chambers opened up to 25cc to drop the CR from 9.8-1 down to 9.1-1, allowing me to run 12-14psi.

Soon be running again then mate, I think you work at a faster rate than me

13.95 1/4 mile on a 2.95 fd. Carnt be that hard to beat!

Pfft sure you can run more than 14psi

If something is worth doing, it's worth doing half of.

New injectors will max out at 14psi I think. Also 14psi is about max on the T2 until I swap over to the GT17.

I've decided to upgrade to the GT17, whilst other bits are coming together. Luckly the manifold works with both turbos, however I need to make another downpipe. Just unsure how to plumb the water cooled turbo. Any suggestions. Inline to heater supply or tapped into the block and returned to the top of the rad?

Have you considered running an auxiliary cooling system for the turbo?

Maybe a heater matrix behind the grill with an electric pump and header tank on the inner wing?

rather than tap into the block how about using the drain plug on the back flywheel side and dump in top hose?
or if you have a bypass pump how about using the pump side of that to push cool water then dump into the top rad?
imo closer to the pump pressure side is better as it will be cooler not traveled threw the engine gathering heat

I had mine from the drain in the back of the block then just into the bottom hose, worked fine.

Thats if youve got the drain plug?

Ive tried drilling the block at the drain plug location as per a couple of other threads, but no joy.

In that case I'd try a bypass off the flow and return on the heater.

Is it possible to use a t-piece from the heater supply, through the turbo and back into the top of the rad? If using the Saab 8mm feeds surely it will not restrict the heater flow.

I've come off the back of the block as there was already a blanking plug there and returned it to the top of the radiator.

Was going to pipe it before the heater but converting from 1/2" to 8mm and didnt fancy my little lad pulling the heater knob and killing the feed to the turbo.

As for T into the heater, water will take the least resistance path and just bypass the turbo.

Yeah that would work fine mate, obviously due to the bore it will just circulate that small amount that it needs.

It's just like putting an extra rad into your house

My only concern is the turbo sits higher than the water level. So won't have the desired syphon effect when the engine is turn off.

Info on watercooling. Doesn't sound like the water level is a big concern

It's such a small volume I'd expect it not to make a difference. Only other option is to have a header tank to raise the head height

Thanks, this suggest the turbo core needs to be below water level. So may have to install a separate header tank, rad and pump. More work and cost.

you dont need a different pump or rad, just make sure one of the turbo coolant lines flows uphill to your heater tank (even if its the top of it) so long as your natural coolant max level is above the turbo core this will be fine.

Just got the head back from SC fully refurbished, 26cc chambers.

I've also commission them to make some 50mm billet CNC spacers to increase runner length with clubman front end.
