alright so i've been reading a bit on Neons.org and i found out that a 420a can hit 200 whp na


I have a spare block sitting here at home and i am going to try this. Now my question is. with 12.0:1 Compression ratio pistons being used what would i have to do fuel wise? I have never done anything N/A with high Compression. All i know is low compression is good for boost. so if any of you can give me a quick run down on the benefits of the 10.5:1 and the 12.0:1 Compression. Thanks T.R
