I have Rebuilt b18a1 bottom end I'm going to be using in a LSV setup in conjuction with a stock rebuilt B16a2 Head. I was wondering what the compression would be sitting around with a set of p73 Pistons attached on the stock LS rods.
Also any reccomendations to toughen up the bottom end to take this added compression. I've read up on adding a girdle and main caps but I don't think this will be neccesary as It will mainly be a daily driver with some occasional fun up to 8k rpm. My guess is compression will be sitting in the mid 12s am i right on this?
I also know I'll need to get this tuned, any reccomended ecu setups for this it will be going into a 99 civic Si. Throw everything you got at me I don't want to just throw this together I want it done right so it can last for a while.

 

hmmm....dont know if you want to be sitting at 12's. Im doing the same project, im getting forged I-beam rods and pr3 pistons to keep it to mid 11s. obviously you will have to get a obd1 ecu, recommend running crome, worked great on my boosted civic

 

Yea that was my first thought was crome. I knew I was going to have to go OBDI. I was originally going to run some PR3s also but then deicided I might as well kick it up a bit more. I picked up a set of RS Machine Forged ITR replicas and hastings piston ringsfor $160. The bottom end has been completely Rebuilt and balanced and has some new LS rods. I'm gonna still take these out and toss in some ARP Bearings and rod bolts for that extra measure. I'm also going to look into getting it align honed if there are any shops in the area that can do it. I have some GSR cams I was going to throw in there but now with teh bump in compression I'm gonna sit down and check out my money situation and see if I can afford some skunk2 stage 2s. I'm gonna be posting up a project thread in a few days here hopefully.
