I was wondering why there was such a big difference between the GB and GC engine break horse power.
Anyone? |

Others here, who are far more qualified than I, will be able to answer this. But, GB is Euro, right? GC, USA. Smog control is my guess. Also possible detuning? |

(IMG:style_emoticons/default/agree.gif) Yup, Steve guessed right - it's smog controlled. That was a big reason why back in 1975 & graduated college & with a steady job (74 grad year was still recession & layoffs) - that I opted for a used 3 year old 73 914-2.0 at $4700, over the new 75 & 76 GC powered 914-2.0's on the dealer lots - even though my monthly payment was a bout the same due to a longer term (used 80% LTV for 36 mos. vs. 100% 5 yr/60 mos.) on the more expensive $7-8k new ones. From 73-76 you'll also see an even bigger HP drop on CA vs. "49 state" vs. ROW 1.7, 1.8 & 2.0 motors & in 75-76 they added the Crap-alytic Converter to CA 914s - further lowering them over 49-state/ROW. This was all smog control induced detuning. CA buyers should note that DMV/CARB still require smog checks biannually & all equipment on 76> MY, whereas <75 are exempt from checks (technically they should still have their smog equipment intact. |

The way I understand it the GA is the detuned US w/ "no smog", GB is the higher compression euro engine & the GC is the detuned US "smog" engine w/ the least amount of bhp. The difference in bhp between the GA vs. the GB is 5 bhp. No idea what the bhp on the GC engine is but it's less than the GA.
