Default 1 3/8"/35mm bypass valve options

Yes... I searched first.

Yes, I know I can order one from BEGi for $85...

What are my other options for a 1 3/8" - 35mm recirculated bypass valve?? No one seems to list the bloody things by size, it's all done by application. This is going on an older FMII I/C setup.


TIA..

Mine has a DSM logo on it. Possibly an evo or an eclipse.

It is a Mitsubishi valve. Do not know car application. Forge makes one in a 1 3/8", but it costs about $150.00.

I'm pretty sure this is it.

Why does it matter you can always get an adapter to the size you need. Buy what works and is cost effective.

Probably 80% of the clamp on style you will find will fit your application.

About 99% of the ones I see listed are 25mm... fits VW/Audi and a bunch of others. No one who sells the DSM pieces seem to list the size, though from Stephanie and Bryans input it appears they're 34/35mm which was what I was looking for.

I'd imagine the 25mm would be adequate, I'd just rather not do a bunch of adapting when it's not needed.
