PI ?

97GTMAN · April 8th, 2011, 12:05 AM

I am working on upgrading my stang. I was wondering if the PI is suggested over non PI. I found the PI heads, Cams, and complete valvetrain for 300. They have about 30000 miles on them. Is this a good deal?

JC316 · April 8th, 2011, 04:22 AM

Yeah, PI swap is a big thing, you won't regret it. $300 is OK, but there are better deals out there. I found some with 15K miles on a fresh rebuild, 3 angle valve job, resurface, etc for $250.

yes it is worth it. you need not to forget about all of the little things you need for the swap the $ adds up quick.

Well I understand that part. I thought you were talking about something bigger. I don't know if they are romeo or not. I'm waiting for the pictures now.

Depends what your future goals are. PI swap will raise the compression too high for a SC or a turbo. Not completely 100% sure on that though someone should chime in here for assurance.

You'll be at about 10.5:1 compression ratio with PI heads and NPI pistons.

For someone with fair knowledge on cars not mustangs in particular about how long would it take to do a full pi swap with aftermarket cams an is it pretty easy to do

You will also need the coolant tube that goes under the intake, and a alternator bracket. There should be write ups containing step by step instructions some where on this site. If not just do a google search and you will find several articles about it.

good luck

Thanks for all your guys help. Yes they are romeo heads. So if I had these put on I can't boost or turbo it? Im not quite sure what my future plans are. What about just the PI cams compared to the stock cams?

Blower Head · April 14th, 2011, 08:22 AM

The pi cams an intake are where most of your gains are. You can run the higher compression of a full swap with a turbo or supercharger as long as you keep the boost down and have a good tune.
