Re: common block core

Brother's Used Auto Parts USA-TX(Mission) 956-580-3349 shows one on car-part from a 91 Spirit for 300 dollars. Don't know how close that is to you but at least its one you can check on.

Re: common block core

Did you want a turbo block or a non-turbo block?

What's the diff? I was under the impression they were the same except for the drain back hole. Non turbo block probably less stressed.

That is the most notable difference the presence or lack thereof of the turbo oil drain back tube hole. As many have theorized, you can just take a N/A block and then drill the needed hole, and that is somewhat true. The reality is though that the turbo block actually has a casting nib at that spot where the hole is machined and this nib is 1/4" or more thick so that the tube has a good solid and deep hole to actually be inserted into. The N/A block(s) that I have seen, do not have this nib for the hole and so therefore, the walls of the hole will only be as wide as the block wall at the oil pan rail is, and that is not very wide. I'm sure that others have drilled the hole, and didn't have any trouble at all getting their tube to seal, but with the wall being thin, the hole needs to be properly machined to get a good very round hole with perpendicular sides to get any sort of good seal and if not, it will be prone to leaking. Of course a generous amount of JB weld might be a short term solution, and it might last for years but then again, many do not know that JBWeld is not petroleum product safe and deteriorates when exposed to grease and oil, especially if it's hot oil.

Maybe a common block N/A block has the nib for the drain back oil tube, I've just not seen one yet and since I had decided to try to go this route a few years ago I did a little homework in the salvage yard and this is what I discovered to be true, at least on the blocks I found.

Of course there will also be the differences in engines with and w/o balance shafts, the crank differences, the oil pan differences, oil pump and the front crank seal retainer plate...but I think most of us realize these as a given.

Re: common block core

i just drilled the oil return in a 93 2.5 na and it had the raised portion and was really thick, just depends on what batch the bock was from i geuss, just like some have the raised potions in the front for a rwd engine mount and some don't, later tbi blocks should also be cross drilled from around 93-95 so thats something to consider if your looking for that

Re: common block core

An '89 2.2 TBI from a Reliant would be a common block.

Other than an 8 bolt flywheel what would it take to use a A523 five speed with this '89 2.2 ? It currently has an automatic. In the past six months I've not seen a single 2.2/2.5 with a manual transmission. I plan to use the motor in a '84 Rampage.

The yard also has a '88 2.2 turbo LeBaron but that can't be a common block.

Re: common block core

I found an '89 2.5 block with 64,000 miles, seems to be a good motor
