I had alot of good advice on my other thread I posted on that one but it seems to have died so I'll start fine tuning. I just pulled my engine I thought it would be like my other cars I had unhook from tranny pull out of top but must not been so pulled the drivers side axle apart oh well. I thought about how far I wanted to stretch the track rules whisch is stock. So I guess I'll just stretch the stockness. How much will it help if I would run the DOHC pistons in the SOHC engine which is a 1995 neon. Planning on some minor head work a better pcm and differnet TB. Which is a better bet a ATX TB or a 3.8 TB? I am trying to do this as cheap as possible any more tips since I'll have engine completely apart? I'm guessing new bearings rings water and oil pump and possible better clutch.thank you

 

DOHC pistons have higher compression. The ATX TB is 52mm.
