Z18et owners

[datsun180sx]

Currently I'm leaning towards using L24 forged conrods and RB30ET 0.50 (86.5mm) forged pistons.

Something I'm worried about is that from my calculations, (which may be wrong as I'm new to this), tell me I would end up with a deck height of -3.85mm.

I'd like to know if this could be a problem and if I am able to shave the z block enough to correct it if it is a problem.

Also if anyone could tell me of a better combination they know of or if I'm even on the right track that would be great.

Now my z18et is running a Z20 block with Z20e pistons (rings are fucked) and Engine is apart in my garage. My plan is to start the build once ive saved somewhat and post as i go on here.
A list of things i plan to do..

1. Block O ringed and bored for rb30 pistons
2. Head reconditioned and braced for high boooost
3. T3/T4 turbo
4 High mount turbo manifold and custom exhaust
5. New ECU out
6. New radiator

Etc etc etc.
All advice and info or opinions will be appreciated and no I won't go SR because its easier haha

I'm not down with Z series specs,
BUt I'd say 3.8mm is going to be too big of a cut for the block. (That's like 150 thou)
