I need to decide what I'm doing engine wise with my 75' 2.0 resto. Cost is becoming an issue...without considering the engine my estimate so far is about $16k. That said I'm not going to do something just b/c it's cheap but I really don't want to go too much higher...

I have the 62k mile 2.0 sitting on the garage floor...it has 40 IDF Webers but has the stock cam...I don't think the case has ever been apart.

I also have a 73' 2.0 that I got at a swap meet about 15 years ago.

Should I just clean up the low mile original engine and put it back in?

Should I start from scratch and build the 73?

What caused the 75' to only have 88 HP vs. the 73's 95? The compression is the same.

Can I do something to the 75 to get it back the lost HP?

If I put the 75' back in should I put in a cam to work with the Webers?

What the heck are these things sticking out of the heads...they were not on any of the 5 other 914's I've had????

I'd put the known good low milage motor in, take off the carbs and go with stockish D-jet since it is a restoration.

for HP you might be able to leave off some of the smog stuff, like air pump (and plug the air ports on the heads), and the egr valve, that will help the engine out, at the very least help it run cooler, Save these parts for later if you you need them later. Check you local smog laws for what you can leave off.

There may be differances in the later systems such as advance curve, and FI mixture that may account for for lower power. The later (1975-1976) 2 liter injectors where a different part number than the early 2 liters, for instance yet i have not heard what the differeance is, and am running them now in my other wise 1974 year injected car.

the later smog control exhaust is more restrictive than the early exhaust, so change out the heat exchangers / muffler to the early 2 liter ones for a performance boost. Stainless exchangers are very nice and weigh less than stock, something to consider, stock ones will work too


PS them things sticking out are the air injector ports, remove them if smog legal to do so. you then plug the hole with a bolt. use plenty of penatrating oil on them, it might be needed.

My mistake...not a factory stock resto...the carbs are going to stay

It looks like the PO plugged them with the plumbing attached in the pic.

The smaller injectors would expain some of the lost HP.
