1.8 is out..., I'm in this up to my eyeballs Options

[TRP]

This escalated quickly! 1.8 is out, getting ready ready for the 2056 to go in.



I will start to clean up the engine bay and the underside of the car to prep for the new motor.]

WoooHooo, the real fun begins

I hope I can get the new one back in! It's still being built, but the new 2.0 AMC heads arrived on Wednesday, they are beautiful. I picked up my tins from the powder coat shop on Friday.

It's official happening.

you know i can't endorse you for rejecting the eye watering power of a stock 1.8.

I'm pretty sure we have a thread somewhere about engine tin markings. Would be nice to get yours documented.

Haa! Yeah, it was hard to see through all the tears in my eyes. (IMG:style_emoticons/default/biggrin.gif)

I hope I can get it back in properly! Im used to basic VW aircooled and gen 1 small block Chevrolet motors. There are more wires and hoses here... I don't know what the heck Im looking at?!

My plan is to use the existing motor as my blueprint for reassemble. (IMG:style_emoticons/default/biggrin.gif)

I was looking at the wiring harness and it looks like someone modified it for something different than stock. There is a dual relay attached to it which has also been modified. I may send the harness out and have it fixed properly. What's the name of the FI harness guru?

What's the name of the FI harness guru?

I already tagged him in my post above.

we got all the engine label and markings info from @TRP when he first got hold of the car.

@TRP - your dual relay (black plastic) is just the replacement type that superceded the original metal ones. standard mod would have been done to allow for wiring it in.
my car is the same - i had it done back in 1989 when i first got the car. even then the metal can dual relay had been superceded. (IMG:style_emoticons/default/beerchug.gif)

@wonkipop - sorry man, I'm weak... (IMG:style_emoticons/default/biggrin.gif)

Thank you all for the info on the wiring harness, I will follow-up about having the harness cleaned up while the motor is being built. I just dont like the black electrical tape on the harness.

With the motor out, I spent last Sunday cleaning the engine bay and cleaned up under the battery tray and under the relay board removed two substantial piles of dirt and junk.Happy to report no holes in the 'floor' of these areas. I did find 4 or 5 pea sized holes near the drain hole under the relay board. On the other side, under thr battery tray, near the drain hole has a 2 or 3" area has some larger holes. I can post photos later from my laptop.

With the new 2.0 AMC heads, ia fellow board member suggested I replace the 1975 1.8 exhaust. So today I took a road trip and picked up some used 2.0 SSI headers, they look used but otherwise in great shape. I spoke with Bruce this week to see if he has all the required heat/cooling bits required to finish replacing the 1975 1.8 heat extractors.

Progress is slow but it's progress.

yes - the exhaust "headers/heat exchanger" on the 75s is pretty weird. hard to believe the engine had the same total horsepower as the 74 given the exhaust system.
esp the way it feeds into a single pipe each side that goes forwards instead of backwards and then does a tight 180 degree turn. (IMG:style_emoticons/default/sad.gif)
i think the idea was to make a kind of quasi thermal reactor out of the exhaust in that section that dealt with unburned hydrocarbons. emissions!!!!

the 74 system is much more plausible. (IMG:style_emoticons/default/biggrin.gif)
