So the H22a came with a open diffed M2A4 Gearbox. It was shorter ratio'd than the Accords but due to the extra rpm the H spun, each gear went longer resulting in shift speed points been the same as the Accord. With the U2q7 gearbox things get more dramatic with the close gearing. And Helical LSD!!

 

The old M2A4 is out.

Changing the stud positions on the new U2Q7 box.

Used a M10x1.25 tap and a 9mm drill.(Dont own imperial drills or 8.9mm drill)

U2Q7 OBD2 to M2A4 OBD1 VSS sensor conversion.

So the differences are the U2Q7 box has no powersteering lines going to it and a different bottom cog. But does have the same electrical plug setup.

 

So process is dismantle sensors, heat cog, remove cog from shaft, then heat other cog, and remove of shaft. Then swap over.

So I had it up on axle stands and fired it up, went the gears and bled the ps system, (vss sensor) and it went well, no grinds or clunks. (other than the surface rust on the discs scratching away lol)

 

I have since test drove it, and its mega! A big difference trust me over the prelude box. 1 -3 are just manic, 4 is about the same 5 is short!

 

The LSD is an animal, you can really feel the outside wheel pull you round. Really has completed the the front end for handling now!  :-D

 

I have a audio file to upload, once I figure out how to separate it from a Go Pro 2 video (I mounted a microphone to the air filter and did a 0-100)
