Hi Everyone, I am needing some advice for what i should do with my engine. I have a 72 1.7 Fi motor with 80k on it at least. The previous owner said that he put all new seals in it and ignition components, but as far as i can tell he did nothing. He also said that it just needed a valve job on the passenger side cylinder head. Also a big lie. when i tested compresson on the engine "after buying it" i found 0 compression on Cyl # 4. I decided to let a volkswalgon mechanic i know work on it since i thought all it needed was a valve seat or something like that replaced. Oh yeah, the engine did run, but not well. Anyways, the mechanic calls me over and shows me the carnige of my top end.

It isnt too bad i guess, but the head, piston and cylinder are shot on #4. The mechanic says that he will pull the pistons and cylinders and use his extensive knowlege of the engines to determine if the bottom end is good or not without disasembling. He did that and told me that the bottom end seems solid and he couldn't see anything wrong with it. He then said that he could get all the new parts for my top end for 1500+ 2000 for labor. I feel that it is worth it to do the labor myself and i know im quite capable, i just need to know the best option for parts, or if i should just start from scratch and build a "biger" engine. Does Raby have any top end kits for something like this? Any advice is appreciated.

I called EASY just now, and they sound great. I can get a compression tested 1.7 longblock for 300 bucks. I inquired about a 2.0 and it would be 1250 w/o injection and 1500 with injection, but no guarentee that the injection would work. My question now is what would be best, spend the money on the 2.0, drive it for a while, save up, purchase one of jakes 2056 kits? Or pull 300 bucks out of my piggy bank and get me cruisin with a 1.7. Then i would need to come up on a 2.0 core to build from still???? Im sure if im patient i could find a 2.0 on craigslist for a good price.
Im likeing this 300$ engine thing though. My mechanic already charged me 450 to pull and inspect my engine. Should have done it myself i guess. With this knowledge, what would you guys do?

I'd do the $300, personally and save pennies for a 2056/2270 kit

I think that i have made a decision. Im going to try the 300$ long block and pray that it is a decent engine. Hopefully then i can drive the car and figure out what rout to take building a 1911 or a 2056 or Biger?? I now need a clutch cable, new clutch and pressure plate, and the correct motor mounts. Where can i get these other than Egay?

If you want to get the car back on the road soon, get the $300 1.7 and do a motor swap. I think for the Raby kits, you need a case, 2.0 crank and 2.0 rods. Any case will do, including the one you have. So all you need to do is keep your eye out for the crank and rods while you're driving your car.

EASY isn't just a motor yard. You can get all your used parts from them.

before you put it in the car - mark the fan for TDC and adjust the valves - may be good advice ??

For future info, check out my blog in my signature block. I built a 1911 using parts from Jake and with his 1.7 -> 2.0 article fast in hand. It lists the components I used for the build. At first I used the FI and have sinced switched to carbs.

I love this motor! And the sound is fantastic. Just something to think about.
