'91 Sterling S50 Swap

[Panici]

In other words there are 4 base versions of the S5x... Euro S50B30, Euro S50b32, US S50B30, and US S52B32

TIL.
Euro S50b30/S50b32 is dual vanos and really has nothing to do with the M50. Heads and everything are completely different.

Whereas the US S50B30/S52B32 is single vanos and basically an upgraded M50/M52.

Not US spec S5x's. All US spec M3 engines came stock with manifolds and a single throttle body instead of the ITBs, which all of the euro engines got from the factory. My engine is a US S50B30. Ide prefer to have a euro S50, but they are quite a bit more pricey to get hold of with low milage in the states.

I was always under the impression that S50's (both S50b30 and the later S50b32) had factory ITBs?

I believe what you have in your car is an S52b32

Please correct me if i'm wrong.

Here are a couple pictures of both in an E30 for your reference:

It was a fun experience for sure. I am open to any suggestions too, ide like to hear what people think

[J.Rizo]

I like builds like this. just fun simple builds.

^^ thanks for the kind words, I am certainly not skimping on anything and do not plan to any time soon.

^ I hope so, thats the goal. And no i haven't, ill have to check it out, thanks for the info.

Long term I am hoping to do a full engine rebuild from top to bottom with higher comp pistons and much hotter cams with a port and polish and upgraded internals, etc, but for now the engine is plenty powerful as it sits.

This will be insane with all the coming mods, porsche killer on the track!

Just realized you're a fellow Vermonter, this thing on New England roads must be sooo much fun! Ever been to Groton state park? It has such a great road that goes straight trough the park with loads of sharp corners and semi-jumps, really recommend it.

The sum of the parts and the length of time hints to an exemplary build!

Hey guys, again sorry for the delay but I know a few people wanted some updates on the current status. Right now the car is put up for the winter, but come spring and summer or warmer weather, there is a list of summer projects that I will be doing. The car will be getting a new JBRacing flywheel and sintered kevlar clutch with the clutch masters pressure plate as well as a rebuilt and resealed transmission. While I am that far in I will be deleting my power steering and replacing the assisted braking system with either the Massive booster delete plate OR the Wilwood pedal set that garagistic sells. To accommodate the upgrade, I will be doing Massive 300x32mm BBK on all four corners of the car. In addition to all of these upgrades, I will be lightening a lot of the interior and electronics, i.e. getting rid of speakers and wires, carpets, antenna, unless wiring, etc. If all goes well Ide like to get the car down to Watkins before next winter, thats the goal.

Thanks for reading let me know what you guys think/ any suggestions, etc. Thank you!

Sorry for the delay, got held up on time. I apologize for the quality in advance. But as the pictures show it is two pieces of ABS plastic (one top cover bolted to a single heat folded piece) with some extra trunk lining I had as a gasket and a big hole cut in the front of it for my 3.5" MAF.

[JeLani]

Any vids of it?

Look forward to seeing more pics when you get them ...

[zcenterb]

Unfortunately, no I don't. Not from when I built it anyway. I can take some tomorrow though. Cars in storage for the winter so its a little tricky to get to at the moment.

^ thank you very much. Honestly I just enjoyed tinkering with it the whole time, it was an awesome project and a very good experience. Im studying to be a mechanical engineer though so I guess its sort of up my alley as they say...

Very nice build, engine bay looks immaculate!

Same here with saving up as I go, the hard part with college is just finding time to finish stuff
