Another 2.7 vs 3.0 question - 2.7 experts please chime in

[lvporschepilot]

Yes. Make it how you want it. That is indeed the most important individual to please.

Remainig stock when stock CIS just plain sucks (sorry guys, it was always a cheap compromise) never made sense to me. Original for the sake of being original, especially when it’s awful, has never made sense to me unless the car were incredibly rare....

Keep the 2.7 ... on a pallet properly lubed and stored....(never say never gonna sell...) and build the 3.0. The 2.7 is a CIS engine and would need p/c's cams, etc all changed to optimize the new intake, and even then running pump gas and single spark plugs you'd be lucky to get a reliable 225 hp.
Twin plug the 2.7 an run 10+:1 cr and you'll get your hp but it'll be a very twitchy motor to drive on the street.
The 3L is a much better platform to work from for a mostly street driven car.

Do it your way. Let the other 75 owners feel that tiny increase in rarity as another hotrod hits the road!

My metal guy is great, didn't cut corners and it's hard to tell its not factory since we used factory parts.

Yes I have a budget and unless I can sell my kids and my dog, the 3.6 with ITBs will have to wait till the kids are old enough to support me. Sorry to the "restore it to original" crowd, this is my 5th 911 and 8th air cooled Porsche project and I'm tired of going stock. I'm finally building the car the way I want it and not for the next guy. If it makes you feel better, I restored my other 7 cars to stock.

Well since it you started.....KICK ASS AND MAKE IT HOW YOU WANT! The good news for you i is backdates do bring good money if you ever sell, and if you don't you can have YOUR 911. I have seen several 3.6 converted cars like mine, once done, sell for very good money. That gives me support for my project, even though I do not have the original parts. It should give you evermore. As others said, look how to store and engine for long term. It can be done so that your engine "doesn't age" and you can get back to it later. I do know someone who did that, and later rebuild their engine and made it into a table.

I do envy you. You are doing yours "all at once." I would like to do that to my '75, but I too have a budget, and my budget does not permit me to do it all at once. I cannot wait to see how this turns out.

My inclination due to originality bias would be rebuild and modify the 2.7L.

Given expense and lack of originality in your proposed finished product; you should install the easiest and most cost effective method to deliver 200hp.

You ever wire a Subaru swap? That’s 50 hours that can be better spent...
