Default Finally got a chance to thoroughly test my 2-3 shift fix

I have original worn OEM motor mounts and a stock 5 speed tranny with no bracing. Only mod is 60 dollar ebay brace.

At 17 psi, the 2-3 shift is rock solid and smooth. I tested it a bunch of times during the dry weather today. Not even close to a missed shift. It was like it was stock again.

It works.

I had a stock mount tore in half and didn't miss a shift.

Yeah that's it. I admit it is not a perfect fit. I ended up having to install it backwards and drill out one of the holes to a wider diameter with the piston part extended slightly.

Here is a pic of it and a pic of it showing the DP clearing the engine bay a little better.

This is still the old turbo (I had trouble getting another one of those autometer threaded nipples and I still have to ceramic coat the DP) and the JGS manifold. The DP is stainless and the flange attached to the turbo is iron. I really should have the DP ceramic coated one of these days.

Is that a pressurized gas shock?

No, it's much simpler- a hollow tube with a teflon spacer and rubber dampeners mounted on the rod. It can be adjusted with the threaded end cap.

How did you make a 57 trim work on a 1.6? That is an insanely large turbo, even for a 1.8.

Lucky? It didn't magically appear in there. No R trans yet. That'll go in with the 2.2L FE.

Is there rubber in that tube?
How does it handle the radiated heat from turbine housing and DP?

There is rubber, but it is an aluminum tube (highly conductive) and the manifold is not actually that hot thanks to the ceramic coat. No worse than a N/A car.

hardly insanely large. The 57 trim has been known to act just like the old 50 trim....its not really all that laggy on a 1.8L, and wouldnt even be too bad on a 1.6L w/ a .48 turbine.

I don't think of aluminum as being highly conductive compared to other metals.

Yeah, the 57trim is just bigger than what most stick on a Miata. It just moves the power band up in the rpm range- but it's still there. With the restrictive internal gate, full cat, resonator and big muffler I'm still getting 12psi at 4200. And I think I could move that down another 200 rpm with some tuning.
