Default rebuild suggestions/questions

I'm building my '02 ls1 to go in my '98 z unstalleda4. This will be a daily driver with stock exhaust. I've got the bearings picked out to order but I still need piston rings. Going to use to stock pistons because it only had 38k miles on it. Block was honed and had new cam bearings put in. Where can I get stock rings or do you think I'll need some bigger than stock?

My other question is for the cam. Thinking of running the 224 cam on the 114 LSA with some 918 springs. I've got some 853 heads that I'm going to run. The car will be daily driven with minor street usage. Would another setup be better or would this run ok? I know you're going to say put a stall in it but it will eventually be a 6-speed car.

Any other suggestions/comments?

if it's a daily driver, the 224, it is a great cam for haulin around town .

One suggestion, definitely upgrade the pistons at least. I think Mahle makes stock piston upgrades that are forged. Don't put the stock ones back in, you'll only regret it later.

I figured it would be ok since it won't be sprayed at all and normally won't see more than 10-15 miles per day except on the weekends.

So does this sound ok? And what about the rings?

If you not gonna push crazy hp, you should be fine to use the stock pistons, and if all you got was a hone, standard size rings will work.

Thank you sir. No crazy numbers for me. Just something to play with a little.

Which version of the 224 cam would be the best for my setup? Or would another cam work better?

The TR224 is a good cam for all around power, this should work very well with your plans/usage. The choice of lsa is up to you (112 or 114).

are either of the two worse on the valvetrain or is it just choppier idle? And which lobes? the xer lobes? I'm going to get the ls7 lifters.

TSP's 224R on a 112 LSA is a killer cam. But if I was you I would spend the money on some good pistons and put in some ARP rod bolts while you got the thing apart.

new arp rod bolts for sure, but absolutely no reason to waist money on pistons. as for clearance on the rings, and the hone, this need to be acuately messured.........

But using the stock pistons with a hone will be ok? Are there bigger rings that will fill in the gap that will take up the space that was honed or how does that work?

well you shouldnt blindly hone it. you need to measure the clearance on the pistons and see if it is in spec or not. if not then go ahead buy oversized pistons and bore/hone to match the piston. you dont match parts to the block, you match the block to the piston. if you just cleaned it up with a light hone and there was no ring groove then you should be fine..........

Yea there was no ring grooves and it was only a very light hone. When you say you should be fine does that mean with stock rings?

With a minimal hone you "should" be able to use standard size rings, but everything should be precisely checked during pre and final assembly.
