Engine build suggestions, Engine suggestions Options

[brooks944]

Hi, great to see the world back! I have a 74 with a 1.8 that was rebuilt with a Webcam, 96mm cylinders an 40 webers. The car has never been right and rich to the point of washing the cylinders. The engine has been out, back in and still not right. My trusted shop thinks it’s a timing issue as well as another local shop who is well known as a 914 pro. I am pretty confident it’s not a carb issue, lots of jet and even other carbs have been tried.

My question is the shop with the car has a 2.0l GA motor that another customer gave him on some other work that’s been in storage. Instead of continuing to struggle with the 1.8, should we use the 2l (assuming it’s a good case, etc), my cylinders and cam to build a 2056? Should match the carbs, but look forward to your input and suggestions.

Thanks,
Rick

I'm trying to figure out if you're looking for repair/setup advice, or if you're just looking for support to justify a 2L upgrade to your wife.

Hey, I'm good with it either way, just not clear what you're asking for, mostly because I'm pretty confused how a rich mixture is a "timing issue" but not involving the system that's sending too much fuel into your engine...and how building a 2L engine is going to resolve that.

(Just tell her we all said it was OK. In fact, invoke "safety" and tell her we said it was safer. Even better, "we'll save money in the long run, honey!" It would not be the first time one of us has done that, you know...) - GA

To be honest im a littlle lost on the ask here as well, and on how cylinder washing could be anything other than to much fuel, and how going to a GA 2.0 (1976cc) from a 1.8 with 96mm barrels (1911cc) would change that?


The 2.0 crank gets you a bit more stroke but uses a different set of rods and pistons than the 1.8 so if you went with the 2.0 you would either need to use the pistons it currently has for a 1976cc or buy a new set of 96mm pistons that work with the 2.0 stroke. 2.0 heads also produce more power but are also more damage prone. You didnt mention anything about the state of the heads on your 1.8 but if they have already been gone through, moving to the 2.0 heads (if you can even find someone to rebuild them) is just more money.

but again, totally lost on what your goals are here.
