And...we're off!

The goal: Build a 2056 from a 1.8L jet. We'll use the 1.8 Case and Heads, new 96mm P&C's, Raby Cam & Valvetrain kit, and, for the moment, put an Ljet or Djet back on it. Eventually it'll get dual carbs, but I can't drop the extra G just yet.

I'll include as manay pics as I can. I got a little ahead of the camera with this so the engine is already out of the car, the tranny and exhaust are off and these pics show the rats nest (Ljet, harness, vacuum), throttle body, intake runners and right side tin coming off.

Had to use the cell phone cam for these, future pics will be better.

GREAT!

It is really hard to stop and take the pictures when you are making progress AND too filthy to touch the camera (or phone especially) I even put my oldest dig camera in the garage and still don't document all the stuff I do.

Good luck with the engine. Sounds like a good plan. Take your time, and check then recheck everything.

Keep those pictures coming!

Question: (I keep kicking this idea around all the time because I have a couple of 1.8 motors lying around just begging to be converted to a 2056). If you put carbs on down the road, won't you need to put in a new cam to take advantage of the carbs?

The way I understand it, no. Jake says that you cam it the same regardless of FI or Carbs. You just won't get the full HP advantage out of the FI, it acts like a fuel governer. FI = 110-115HP, Carbs = 120-125HP.

Herb, I stopped in for a couple hours on Monday and went to town. You busy Friday? I've got a mid-day meeting but would like to do some more on both our cars.

Have I mentioned that I'm STOKED!! I intend to drive this bad boy to ECC this fall! (IMG:style_emoticons/default/smash.gif) (IMG:style_emoticons/default/welder.gif) (IMG:style_emoticons/default/driving.gif) (IMG:style_emoticons/default/beerchug.gif)

did you go with the 9550 cam? remember NOT to run more than 8.3:1 if you'll be running o.e. injection. thats why you'll limit yourself in h.p. if you dont keep comp. down and run the f.i. you'll probably burn a piston. ask many of the members here.

good luck with the build, and definately have a plan on what carburation your engine will run on the finished project. just be careful not to damage all that expense and effort before the carb install

Good for you. You do realize that in addition to what you listed in your first post that you also need a 71mm stroke crank and 2.0 rods to make 2056 right? Otherwise, you're creating a 1911.

Sorry Herb, got roped into house projects today. The wife discovered I was off today and took the day off too. I'll call you this weekend and re-schedule.

Kenny, thanx for the comp ratio info. I hope to have the carbs by the time I finish the build so I don't have to F with the FI. I am purchasing the 9550 cam.

Gint, I'm on it. I intent to harvest a crank and rods from one of Herb's 2.0 motors.

Have I mentioned Herb rocks?! I really appreciate the time, the garage, the tools......what kind of beer do you like again?

Herb and I finally got the case cracked. 30 years of wear and tear were very evident. It was also apparent that the heads had been off as well. Each cylinder had a stack of 4 shims. I never did a leak down test on the motor because I knew I was gonna pull it, but I'll bet you can look at the pics and tell me what the results would have been!

Now it's of to Jake's with the crank, flywheel, clutch, and rods for balancing.

Here's a look at what we found, btw, it was dirty!

Caution: Dirty engine porn!
