Well I was at my friend's shop this weekend watching him press and machine sleeves for a nissan SR20 block. He does the machining work for AEBS(Advanced Engine Breathing Systems). For those of you who follow import(Japanese) you likel know who they are. It's pretty amazing to see a machined sleeve pressed into the block and then two more final cuts are made, one to even the sleeve with the top of the block then one more to remove 0.003 off the entire top of the block. The sleeves were designed for 50psi in mind so the blocks end up being quite sturdy and ready for boost. I guess I'm glad audi 1.8t blocks are as strong as they are stock...

Re: Yup thats because the sr20 block is aluminum and we got iron.
