[Mk2] [Turbo] turbo engine build

[SamBurton]

Hello all,
Finally getting round to building my turbo engine. So my plan is that I have forged internals for the block, this is a rev 1 block. What would be the best combination of block / head. I am running a apexi power fc so already cut out the maf. Oh the car is a rev 2 turbo.

What is your engine design?

What power have you designed for, what boost, what rev for max power, what fuel will you use, what compression ratio etc. etc.

rev2 block and rev3 head is meant to be the best way to go

5S block, rev3+ head

What is the diffrent in the different rev blocks? I had been told the the rev 3 is a good head to use

Best head would be the beams head (port angles into the valves are greatly improved), failing that Rev 3/4/5 is the one to go for.

Rev 1 & 2 blocks are supposed to have thicker cylinder walls, but when they let go it seems to be around the water pump- possibly because people don't replace the bolt that is removed when the a/c compressor is removed.

Rev 3/4/5 blocks delete this issue, and some of the rev5 blocks are supposed to be stronger still.

The 5S block has thicker cylinder walls again, and is supposed the be the one to go for if you want big power and less chance of a cracked block
