M35 Turbo With 2871 Garrett Core?

[TALWill]

Hi all,

I picked up a second hand turbo a while back that was advertised as being a hiflowed turbo with a Garrett 2871 core. When I got there it looked stock and not hiflowed. Eneded up getting it cheap with view of just rebuilding it.

It occurred to me today that maybe that glass was actually half full and I should look into it more first.

Is there anyway to tell what the core actually is?

If it was a 2871 core what would it be like on a stock car with one of Scotties dump pipes and a hiflow cat?

Thanks everyone

Looks like a bigger comp wheel with the standard turbine(also meaning ball bearing). I've seen the Japs do this. Would give good response with an improvement in power. The bigger comp would bring the turbine speed down a touch meaning you could prob get away with more boost before the ceramic turbine falls off. I wouldn't go over 18-19 psi.

I would expect it to be very responsive...may even want to compressor surge.

Thanks mate, that's good info to have

Is there any value in doing work to the housings? The pictures of hiflowed ones seem to have a lot of the material in the exhaust side removed.

Also will the ceramic stock wheel be OK to use. Really don't want to have to do this job twice!

Ceramic wheel will fail when boost is above stock(an even on stock boost). Just a matter of when.

You could go to a bigger turbine at the expense of spool. Would gain power, reliability however. Be very careful about going too big a turbo as they don't work on an M35 without a huge amount of ancillary work.

That turbo with one of Scotty's dump would drive fantastic.

Double check the turbine wheel material. Hard to tell from the picture

Looks like your in luck. Your turbine is a 10 blade and the stock is a 9 blade. Also looks to have a less aggressive trim, meaning more flow.
