2G eclipse with a 6 bolt motor

Needless to say, I had a motor rebuilt for me and requested it to be a direct bolt up to a 97 eclipse gsx. I went to pick it up today after waiting a month for it and there was a nice shinny 6 bolt motor waiting for me. Well, besides the fact I know about the crankwalk on a 7 bolt, I just wanted a simple replacement.

I agreed to take the motor and discussed the changes, will be getting the necessary parts free of charge, since it was not my mistake. The block and head are both from a 92 eclipse. The obvious change would be the 6 bolt flywheel but what other parts must be changed or altered for it to fit correctly.

Do you have a point?

I think he wants a list of all the parts needed to do the swap.

Can I barrow 50 cents?

and no you cannot barrow 50 cents.

From what I had been informed of, the water pipe, water pump, flywheel, oil filter, oil filter housing, CAS, and thermostat housing are different. Also some grinding on the mount may have to be done. I was just attempting to see if there are other changes or parts I may have to go and buy or swap out also. I guess I may find out on my own as I piece this jigsaw back together, but it would be nice if I got some heads up.

Thanks

Check out my project thread listed in my sig... I have pictures and information of the things that are needed to put the 6 bolt into a 2g... I am almost done with the project too so you will find "most" of the info there... I am just getting to wiring everything up now, so I haven't listed any electrical changes yet.

**EDIT**
Most of the info geared towards the differences are on the last few pages of the thread... I gotta get a cleaner version of that thread put together as a write-up when the entire project is finished.

Here is a good write up with all the differances

thanks for the info, that is exactly what i was looking for but having trouble finding

are the flywheel bolts exactly the same with a 6 bolt and 7 bolt, as in size

Yes, I stole the bolts from my 7 bolt for the 6 bolt when I was putting it back together.

just wondering, ive already tried that, but i was wondering if the length of them was longer in the 6 bolt style. I put one in all the way and it seems like there the hole is about 4mm deeper than the lenght of the bolt, though they are the same thread and width. I dont remember if my 7 bolt had the same gap.

The hole is 4mm deeper than the bolt? That sounds about perfect to me.

As long as it goes all the way in whats the problem :iceslolan

The more threads holding it, the better...

ive came across some other differences though, mainly with the timing side. of course, i still have a 2g tensioner and tensioner arm. The tensioner is the 97 up version where it has a single bolt on each side, so I need the other one. I was also told the arm could still be used, if you shave some of the water pump... sounds risky though. could the arm be trimmed to fit? I know the tensioner isn't adjustable in height like it is on the 420a motor. is the arm on the 1G a different lenght?

Yeah, a lot... Use the 6 bolt stuff for that. It'll be easier... I would never do any "trimming" on my water pump. The only thing I had to do some trimming on was the 7 bolt motor mount...

Here's the difference between a 1g and 2g motor mount and what needs trimmed with the red line.

Sorry, I don't have a good picture of the timing stuff without the cover on to show you the differences...

I have already trimmed the mount. Not enough though. I still have to take off another mm or 2 to get the water pump to fit. I'll prolly sell the 2g arm on ebay and buy the 1g arm at the same time.

There still seems to be a couple more issues. Anyone know how to fill a hole then retap it? This hole on the water pump on the bottom is twice the size as the one on the left.

Are you using a 1g or 2g water pump?

The only way I know how to fill a hole and retap it is welding it shut then drilling and tapping it. Thats how i've always done it. Dad owns a machine shop so its easy to get my hands on the right equipment too.

My dad has a thousand tools in his garage, but that doesnt mean he has the right ones I need. I did purchase the 1g water pump but if you look at the hole on the left, it is the regular M8 size, where as the hole that doesnt even look circular, is slightly larger than an M10 with no threads. The holes on the new pump are all the same size and there is no way a larger bolt will fit. I am not going to destroy the pump and void the warranty and I dont want to modify anything else and risk it leaking. how should it be welded shut?

i found that cast iron is hard to weld properly, but jb weld can be used to fill iron. it says up to 600ºF. i hope my engine never gets that hot. fill it, drill it, tap it. Has anyone else done this?

Aren't the water pumps made out of aluminum, and not cast? IIRC, the blocks are cast, but the water pump, oil pump, and all that shit is aluminum.

I also thought the pump was aluminum...because the blocks are definatly cast iron...

i was referring to filling the hole in the block, in the picture i posted on here the other day. i need to fill 1 of the 5 holes on the block then retap it so the water pump has the chance at making a good seal.
