Morghen - one company here in Poland makes it for 924/931 and 944 with any logo as you want. They need few days to produce a set... cost is approx 40 Euros or even less for set of 4 carpets, depending on exchange rate. The quality is great... and you can order many different colours of carpets/logo/surrounding.

Khal: photo for you

Good work! But the exhaust pipe looks very restrictive. Not that it should be some big boy racer fart can but that looks really small. It isn't a good thing for a turbocharged car.

hey man I was wondering whats the difference between the gear boxes, is the 931 better? if so why ?

McGyver · Posted: Fri Sep 21, 2012 2:45 am Post subject:

Difference between which gear boxes? G31 I had to say is made for racing... Dogleg pattern makes it quite good on track, when you use 2-nd and 3-rd gear most of the time. I made 120km/h on 2-nd and about 180km/h on 3-rd with 924n/a engine... with Turbo maybe it goes some higher. G31 had problems with synchro rings but I think after replacing for new one made today that should last almost forever

I wish to buy one set from Ideola Garage to fix my gearbox... but I have to sell kidney or something first because my work is not enough profitable last times.
G31 is "big brother" of G16 and looks external the same... but internal is much stronger - even input shaft is 25mm instead of 20 in G16 but it's for Turbo so should be stronger.

I'm not sure how about rest gearboxes. Audi ones from 924n/a are definitely much better and don't have problems with synchro rings... but they're not strong enough for Turbo.
So only way is to use 944 gearbox... which had 25mm input shaft, no synchro problems, and should be strong enough to work with Turbo engine, especially 944 Turbo versions

Morghen got 944S2 gearbox connected to 931 engine and that setup works great... not sure is better/faster than G31 but no synchros problem is much more for it.
