Rebuild a 2.7L or 3.0L six motor, which is cheaper? Options

[boxsterfan]

Which /6 motor is cheaper to rebuild? 2.7L or the 3.0L?

1. Assume core motor is in good condtion and no crazy findings when you tear it down.
2. Assume you are building the motor for longevity
3. You are putting this in a 914/6 conversion (was /4)

a stock 3.2 with Motronic-DME will give you 205-217 hp - with no more drama to install in your conversion project than any other -6 choice

getting 200hp out of a 2.7 or smaller is not an average nor cheap build - (BTDT - a 2.8 on a 2.4, and a 2.7RS on a new case)

the advice from the guys above is spot-on

the "cheapest' trick is to find a decent complete 3.2 without big miles on it - but that's mostly a "barn find" dream

(a few yrs ago PMS told me they'd quit doing 3.2 conversions cuz they could not find any decent ones that didn't need a rebuild)

if you find a 3.2 needing top end work (highly likely on any older 3.2), be aware that the bottom ends will go 250K easy, so you may avoid a complete teardown)

fwiw last year i sold a 3.2 with 188K miles on it, needing a valve job, with all the injection, etc; but no alt-fan & no DME or harness - i advertised it at $5500 on Craigs and had 6 guys panting for it in one day - a guy came all the way from LA for it with cash in hand (a DME & harness is another grand, alt-fan another $600) - (i previously advert it here on world for $7500 COMPLETE with no takers, so i decided it was worth more parted out & stripped it to long block, sold the FW, clutch & various other parts - got more than my original ask in the end)

best -shop for a whole wrecked Carrera & hope for one with acceptable miles on it or some verifiable evidence of prior work - just have your checkbook ready
