[75 911s]

Hi guys,

First and foremost, I have limited engine building experience. I've torn down and rebuilt a v8 with help but never a Porsche engine. I apologize in advance as I only have basic knowledge of engine building, but I'm mechanically inclined and willing and excited to rebuild my 2.7. Having said that, I found a local seller with some juicy parts:

JE 90mm 10.5:1 Pistons, rings and nikasil Cylinders part 261664 (New)

DC racing 911 E cams (New) 3.0-3.3 mm

Rebuilt heads with standard bore from a 75.

It's difficult to price these items out so I'm wondering what you think ballpark you might be inclined to pay for all of these items. The heads are standard so I believe 32mm. Should I port them to 36mm?

A little about my rebuild goals. My car is a 1975 911s California engine 655xxxx type 911/44

I've removed the emissions stuff and am running SSI HEs. I've rebuilt the fuel system and cleaned up the motor but it's got 153k miles and I only put a front mount cooler on last year, so most of those 40 years have been without a front cooler. One through bolt is stripped in the back. It leaks at the case split and a bit at the heads in some places. all in all, it's quite worn and no matter how hard I try, I can't kill all the leaks.

I'll be running 91 gas with primarily street use and some possible future DE

I want to use my numbers matching 7R 2.7 case. I plan to ship to ollies to have it machined with the typical upgrades (oil bypass) etc

My rebuild budget is about 10k. I will do the tear down and assembly. A local shop will tune.

Intake will be webers for first phase with maybe some nicer pmo / efi option down the road.

I plan to keep the SSI. it's running to a hacked 2/2 bischoff muffler.

I like Bruce Anderson's recommendation for a street use 2.7 but he's using 95mm euro Carrera RS p/c, 911e cams, and webers.

What would you recommend?
