Engine Rebuild

I'm tearing apart my engine for a complete rebuild. I have a couple general questions...
first off, is there anything I need to watch out for when taking it apart or putting it back together? (it's completely stock)
secondly, when I rebuild it I want it to have some more power. My plan is to bore it 20 over and add high compression pistons, does anyone have any other ideas? I do need to keep it smog legal, because it's my daily driver and I live in California.
Thanks for the help,
Steve

Re: Engine Rebuild

You might want to take a look at the 1.3 head with the larger 1.6 exhaust valves that Dave at Asian Auto Parts of AZ has on his web site. With C.A.R.B. legal Doug Thorley headers and 2" cat and exhaust, that would be a sweet set up.

Re: Engine Rebuild

I had to buy new head bolts when I went back together with my 1.3, the originals would not retorque. They are designed to stretch as I later found out. I had to order through the dealer which caused a small delay in putting it back together. I went ahead and got new main bearing cap bolts too, as they "felt" funny when torqueing them down. Might be worth considering.
good luck

Re: Engine Rebuild

A cam will likely make it more difficult for you to pass CA smog inspections. Fitting the larger exhaust valves from an 8-valve 1600 makes a big difference in power, especially when complimented with a Thorley header (the only CARB-approved header) and a good 2-inch exhaust. Raising the compression with pistons and milling down the head will also hurt emissions but will make for a lot more power.

Also, when reinstalling the head, make sure you get the head gasket aligned the right way or you'll toast your head. The gasket is symmetrical except for a hole that must align over the oil galley. Too many heads have been ruined due to backwards head gaskets.

Best of luck to you!

Re: Engine Rebuild

I wasn't planning on milling the head, in fact I want to do as little machining as possible. that is why I'm only going 20 over on the block. what do I have to do to the head to get the 1.6 valves to work? how bad will high comp pistons effect emissions, will it pass smog? I was already planning on 2" exhaust and the doug thorley headers, probably a dynomax honeycomb cat and I was thinking about the Hardcore muffler. I don't wanna race this thing or anything, in fact the slower the better on the pocket book (heavy foot). I just want some power so I'm not draggin' a$$ trying to get up the mountain or grapevine. Thanks for all the help!!!

Re: Engine Rebuild

Zukiman , that 1.6 ex valve sounds like the hot ticket.
Header,free flow exhaust & higher compression each usually increase mpg along w/power.
How about the larger valve - power & mpg ? Any research into that ?
Anybody tried Just the ex valve w/valve job ?

That's all from this corner
