Tell you what then, seeing as you're getting this block all sorted & you've tipped money into it already then how does this sound?

Pick up a complete turbo car that's either been wrapped round a tree etc, or got a rod through it's belly but good blower, hopefully good head & all the electronics & other bits you need to convert to GTE spec?

Then get your man at the shop to drill the oil drain & flush the block as per cre, and instead of buying N/A pistons for whatever oversize the bores are at, just get Turbo ones.

That way you get a good as new (better than new bearing in mind overbore) block & all the kit you need to make a real GTE motor... Plus you'll have a certain amount of other spares from the wreck which you can either swap to your car if better, or sell off to make some of your outlay back.

If going turbo, I would definitely avoid boring the block unless it is absolutely required.

I recommend installing forged pistons and new stock rods (forged would be even better). Definitely install a GTE oil pump; it's a much higher flowing pump and you'll want it when you add oil cooler and turbo.

Later I would install upgraded injectors and swap in GTE electronics and upgraded fuel pump.

Cre got a new avatar!! cool

so the build continues. just as promised my rebuild kit has come in. new pistons, gaskets, water pump and what-not. free 2 day shipping!!! $275

so due to this being my DD and my boss saying im gonna start work again soon, i decided to keep in N/A but going with Cre's advice i wont invest into this motor till i can get a new one and go turbo. after this build is dont ill invest in other things.

soo today im going to the machine shop so i can drop off the pistons and they can test the cylinders and give me my block back! sweeeet. new head still hasnt come back yet. oh and since me and the lady are going to repaint the body eventually...... we got busy

covers look pretty dang good

amazing having a girl that can wrench
