Real quick can you put a non S block into a S car and swap over everything to make it a supercharged motor? I know it's weird question but just wasn't sure if the two motors are interchangable with a parts swap.

 

that i do not know, im sure the cooper s bottom end is differnt than a non s, but i could be worng

 

Thats what I was thinking but I was hoping someone could tell me exactly....

 

General consensus seems to be that it is more trouble and money than its worth.

 

NO. The supercharged engine internals are different - it is a purpose built supercharged engine, pistons, rods....

 

Right but are the outsides the same?

The reason I am asking is that we got an engine from a salvager and everything bolted up but something isn't right. So i was wondering without pulling the entire motor apart was there a way to tell if a block is a S or non S engine.

 

+1 on internals. Supercharged motors have a forged crank, crack-forged connecting rods, and forged pistons. The block may be the same, but all internals would have to be moved over. The pistons are also dished to get a base compression of 8.3:1, which allows for the application of boost. Regular MINI pistons generate 10.6:1 compression.

 

He's asking if a NON-S engine will bolt up and fit/run in an S.

 

Post 1 "Real quick can you put a non S block into a S car and swap over everything to make it a supercharged motor?" and the answer is still no, too many internals necessary.

 

Whether the combo would work or not, I think the question is; caqn it be bolted together and "look" right.

In which case, I think so. The heads, intakemani, and exhaust mani are interchangeable. Yes there are differences in specs and such, but things bolt up.

The engine block *should* have a VIN on it, which would reveal any info you may be missing.

 

A few easy things to look at....look at the bolts where the thermostat/housing was/should have been connected to on an S.....were they are rust filled? I think he water pump/thermostat on the regular mini in on the side of the block next to the accessory belt....on the S it on the far side.... How about the the SC bolt holes....were the holes were clean?...if they have never had a bolt inserted in them since it was cast....you have a r-50 block.
The VIN # check would be pretty fool proof if you can find the stamped #.

 

Even if you can bolt the non "S" engine block into, there 2 different PNs, 1 "S", 1 Cooper for the block. Could be undrilled mounting bosses, main bearing bore....

11117581399 = Cooper
11117520126 = "S"

DON'T DO IT!!! S BLOCK'S HAVE OIL JETS AND VANES TO COOL BENEATH THE PISTONS NON S DOES NOT YOU WILL COOK THE ENGINE BEFORE YOUR NEXT OIL CHANGE+CRANK WONT FIT

 

ANYWAY, YOU CAN DO IT USING A COMPLETE SHORT BLOCK IT JUST GOING TO RUN A HIGHER COMPRESSION AND A WEAKER ENGINE

 

Thanks guys. the question was if you could bolt on all the parts from a supercharged motor to a non block. I think the answer is yes. Thanks for all the input.

 

I saw a vendor had a sale of two brand new GEN1 engines in the market place for around $3500...Couldn't you drop that engine into the car?

 

Sorry it's no longer listed.
