Hi everyone, given how awesome this site is and the wealth of knowledge I’d like to do what seems like the best option for me and that is get my 914 on the road and keep it on the road. Need some help, advice, how to’s, anything that could help me build the motor. I’m mechanically inclined, I’ve built an engine before on a 2.5 Nissan Sentra (i know dark times before) but only did the easy stuff like assemble after a machinist put the crank and rods in. I’ve been restoring in the garage for about a month or so and although the engine “ran” when parked 20 years ago it seems like the right time to rebuild. What parts should I use, any good videos to watch, anything to read, how can an average guy like me split the case open and handle the rebuild step by step while killing time in the garage? Open to suggestions on displacement, fuel delivery, places for machine work, any suggestions and even sarcasm are accepted. Big fan of Ian Karr so have been watching his videos, just waiting for the final release of his engine build for more insight Thanks everyone! (IMG:style_emoticons/default/sawzall-smiley.gif)

Hey dude. First I would take it apart and look and see what you have that is still good. I had my 1.7 case / heads cut for 2.0 cylinders and put in a 2.0 crank and rods. You don't have to go crazy from there. I ported the heads, put in a counter balanced crank, an appropriate cam, cut the flywheel and put in a better flowing exhaust. Fuel delivery is a hot topic. If your a fuel injection fan lots of people can help here. I went a different way. It's not a hard engine to build, take your time. I see you are another desert dweller, I'm adding a front oil cooler for summer.

Did you do most of the work yourself and if so where did you source the parts? I’m interested in what you did with the flywheel and the exhaust route you took? I’m not faithful to FI or carbs but I’m super interested in what carbs you went with and how you like it as I’m not opposed to anything. That’s awesome, I’m hoping by summer I have the targa top off and cruising around maybe we’ll bump into each other! (IMG:style_emoticons/default/beerchug.gif) |

(IMG:style_emoticons/default/beerchug.gif) Lot's of places to get parts for the engine. How much do you want to spend. Flywheel I had cut to 13 lbs, that is a plus-minus modification. Quick deceleration but less mass for driving around town. Takes a little more work from light to light, but fun in the twisties. Most of the aftermarket stainless steel heat exchangers are 1 1/8 " ID or bigger. They come in a 1.7 and a 2.0 version. Easier to get a good exhaust system for the 2.0 version. I'm running weber 40 idf with cb performance spray bars and venturi kits. I like them. |

What parts and places did you go with? Would love some examples. Being in the desert, where did you get the machining done to make all of it fit? Debating the flywheel option, do the 2.0 exhaust systems mount to the 1.7? |
