my m1009 engine rebuild, turbo addition, AC addition, and trans swap

[snakepliskin]

after not getting to drive my cucv for almost six months mostly because busy at work and other broke downs in the way have finally gotten started on fixin it up and i have bitten off a lot to chew

the engine and trans are out of the truck now and the engine is already apart with block and heads currently at the machine shop

have already scored some turbo stuff at the pull it yerself junk yard from a 6.5 1995 and 1994 models

got the accessory brackets from the 94 also so i can go to serpentine belt setup and facilitate ac pump mounting

got a 700r4 from a 1988 and the np243 case to go with it to swap with the nv4500 ive already put in it and dont like to much

also have lots of spare 6.2 parts from a humvee motor i bought off govliquidation but some stuff in it aint so great it seems the motor must have been out in the rain a while

here is some more

 

[snakepliskin]

the precombustion cups in the cucv heads are the older style and the humvee heads have the newer ones can you just knock these out with a punch and swap them?

 

[chevyCUCV]

Nice build you have got going on
I am surprised you dont like the nv4500, anything specific about it?
And that tcase is a np241 i believe

And the precups should punch out with a brass punch. Bigger is better, since you are going turbo so if you can get a set off a turbo motor/6.5 you will be better off, with a slight drop in compression ratio.

couple reasons for the nv4500 leaving

my wife drives manual just fine but cannot drive the truck with that trans ( i have no idea why)

most of my driving is in city so lots of clutch work required

i used the hydraulic setup with the advance adapters bellhousing and slave cylinder mount bracket they sell and used the gm slave cylinder they suggested but never have been able to get the clutch to fully disengage with that set up. ended up burning up a clutch plate in about a year driving (about 20k miles) even messing with it over and over trying to get it to work

had to replace the starter during that time and the AA bellhousing made it a problem

swollen left leg!

 

[snakepliskin]

you are correct np241 it is

my bad for the typo

 

[snakepliskin]

here is some of the rebuild kit stuff, i bought a kit from someone on ebay advertising as a kit from the military. i dont know about the validity of that but it does seem like a very thorough kit as any engine kit should be of course. the only thing that really wasnt there was valve seals so i just told the machine shop to order them.

i definitely jumped the gun buying a kit before even taking the motor out of the truck though and i didnt even realize it until the machinist asked if i had measured the bores to know that those pistons would be the right size

 

[snakepliskin]

i managed to paint the valve covers last night and got the crankshaft to the machinist today

Only heard bad things about the advance adapters bellhousing

Good luck with a slushbox, ill take the nv4500 off your hands

Wow, sounds like what I have and still doing lol.. This time is the last, I swear, if she doesn't preform like it should, I am going to bugout and nuke it from orbit..All I have done to mine I would have better off buying a civy k-5 and painting it green lol.. I got that green crap on the brain.

 

[snakepliskin]

yeah maybe. im absolutely sure that this thing has turned into a money hole for sure. but i do enjoy driving it. im headed back to the pull apart tomorrow to fish out some more parts

 

[snakepliskin]

got some junk yard stuff over the weekend, the backing plate/timing cover for a reverse rotation water pump is also reverse. the one i found was bent so i dont know if it will be ok

 

[snakepliskin]

spent some time this morning busting up the turbo in anticipation of the rebuild kit i got coming in for it

 

[snakepliskin]

today at wally world i found this can and thought it might fit on top of the intake manifold it said stainless steel on the label but i figured i would just silver braze on a 2" outlet. for $7 i figured if it wouldnt fit i would just say oh look honey i bought you this great new kitchen junk. it does fit and quite well too. also through some walmart magic of metallurgy magnets stick to it so i dont know

 

[snakepliskin]

i know this drives the oil pump but what is the electronical part on top do?

 

[patracy]

Tach sender. You're missing the vacuum pump though. But then again, you're going to a 700R4, so it's not an issue.

 

[snakepliskin]

do you know how you would hook it up?

 

[chevyCUCV]

i know this drives the oil pump but what is the electronical part on top do?

I think thats a rare part right there, similar to the humvee tach?

 

[akonitony]

A rare part indeed! As for hooking it up, I'd use my hands.

 

[snakepliskin]

is it usable with like an aftermarket tach from the parts store?
whats so rare about it?
