I have decided to change my plans regarding trying to seal the cylinders.

I went ahead and cleaned the cooling area of the block, sealed off the water pump openings, and finally did a short fill of block filler. Basically raising the floor by 1.5".

This is a temporary engine and short of creating some sort of deck plate, I don't see a solid solution to be able to run high boost at all.

As most of the heat is transferred at the cylinder tops I'm hoping that it will run cool enough.


So now the current plan is to:

Change head studs
Use wide fire gasket to determine if problem is pseudo solved
Install huge oil cooler under my intercooler

If it appears that this helps, I will then try another cometic or go ahead with the o ringed head and wide fire hg

I'm letting it sit this whole week to harden and installing the oil cooler among other things.

Fingers crossed...

I was going to do a twin charge until I used anti lag. Dave (dnovak) will probably do a compound setup. Keep an eye out for that.

I'm just going to focus on the 16v engines, and if they don't do it for me I'll join those who have traded for something else

Twincharging is a cool idea. I saw Volkswagen finally made one. Cool idea not sure how much total power could be made.

i hope that arp studs and o-ringed block will pin down the cylinders so they will not move around.
we will see this summer if it will help or if i should rip out the engine and replace it with a audi 5 cylinder instead
