I have a 1990 crx si with the original d16a6. I wont to build the original motor. The head has had a value job and has been shaved. Machine shop has stated that the block needs to be bored out at least .10000. What is the best bore to go with being I have to bore it? And what pistons and rods are recommend? Trying to have a 250+ hp daily driver. Will be boosting but I want the motor right first. Car hasn't been on the road in 15 years.
I'll be running stock si wheels myself. This is before I pulled the motor. Motor will be done tomorrow or at least at first machine shop. Time to find a good set of over sized piston. 10 or 20 thousandths.
If you tune it correctly then there’s no reason for low compression. At some point, when your dynamic compression ratio gets high enough, you’ll reach the knock limit of the fuel and will either need higher octane fuel, reduced timing, or a lower dynamic compression ratio to avoid detonation.
Every time you work under the hood you place your hands or a tool on the VC at some point leaving oily or greasy stains on it I have only had black since.
I'm real interested in how it holds up over time, is it paint or powder coat?
Where yours is sanded to raw on the emblem I am thinking I would paint the emblem/lettering in white on the black valve cover and black on the white one. For the raw one I think I would try to go for the shaved smooth look and have no emblem or lettering at all.
I also like the black valve cover. And this is high temperature paint. I took it all the way down. High temp primer, high temp white, then high temp clear. And I shaved the letters off with a razor before I shot the clear. If you do that be super careful.
If you’re going to assemble the engine and trans outside the car and drop it all in together, you may want to take the engine wiring harness out of the bay so you can hook everything up while the engine is out of the car. Then you’ll only have to plug in the two harness connectors and the resistor box once the engine is in.
