Happy Father’s Day gentlemen.
I just drove a ‘74 2.0 car from central OR down the coast back to SoCal (great trip, car was totally reliable) and somewhere on a single lane carving through the redwoods outside Eureka I wondered “yeah, the extra power would be nice but would it make the car feel heavier”. So,is there a trade off in perceived weight or having the car be less eager to dance that comes with a /6 conversion? My intention is to keep whatever car I covert a narrow body and subtle so built GTs aren’t really the best point of feedback. Thanks! |

^ Some great input above.
My 2.2 six conversion definitely doesn't feel as light or "momentum" as it did as a four, but I wouldn't go back. It just feels special in a way that's hard to describe. The car always felt like cheap fun—in the GOOD way Miatas and MR2s do—as a four, but feels more exotic and sophisticated as a six. Heavier, too. And maybe not quite as flingable...but I hold out hope that I can dial the suspension in further. Not that it's bad...but there's something very cool about the lighter fours. Any six is going to require a brake upgrade, but PMB's alloy Brembo setup or any 911 front brakes should be enough. Count on a five-lug conversion as well, if you go for the latter. If you want to keep the body narrow, I think 180-200hp is the sweet spot—so I'd look at hot 2.2s, 2.4s, and other engines up to the SC 3.0 or maybe a 3.2 that's dead stock. Of course, the bigger the displacement, the more you get into the conversion. Oil coolers, 915s, etc add a lot to the cost. I like the 2.2 because you can get nice hp (I am not wishing for more power) without big torque, which is what starts upsetting the transmission, driveline, and/or chassis. YMMV here. The engine in my car is a 190-200hp E/S 2.2, and it feels and sounds great. There are times where I wish it was injected instead of carbureted, but that wasn't in the budget. If you want civilized, I wonder about a 2.4 MFI or even 2.4 CIS? Or just a nice 2.7 or 3.0 CIS? Add a stock muflfer and I suspect that would be a very nice package.... Once you go past 200hp, I'm starting to think about flares and all sorts of other stuff. you're soon re-engineering the car—not that there's anything wrong with that!

Comparerd to my GT project with the 2.0 911 T engine it was a friggin' powerhouse |
