G-Teched my 1.6TD - Part 2

[935racer]

Yes he has an o2o trans, I can't see any advantage of using the 02a box with  o2j internals. Mark when we find a cheap o2j I'll throw in a nice lsd and make some custom mounts for the tranny and the shifter box etc, shouldn't be too hard. Seeing how I gotta rip the whole tranny apart I can powdercoat the transmission case! That would be sick.

[RedRotors]

Perhaps im still asleep, but both, O2A and O2J is the same tranny, with few minor difference on the casing. Both has cable shift and hydro clutch.

I have a O2A from a 98 TDI and when i removed the one on my Golf to put the Peloquin, i compared the outside and they are very closed.. They share the almost the same gear set.. R&P from the 02A is 3.15 where the 02J is 3.38..

This is true. The 02A and 02J are very similar and some parts are interchangeable.

[dubCanuck1]

Yep. The only difference that should be apparent is that the 02A has a different mount above the driver's axle, but that should mount directly to the mount for the 02C. As mentioned before, I've got the part coming in and will have the info for you soon.

I was under the assumption you had an 020 trans? How do you plan to retain your stock linkage shifter?

Yes, 020 and I was wrong about retaining the stock linkage shifter. This is what I was thinking:

1) MKIII 02A shifter (bolts right in).
2) 02A tranny (bolts right in).
3) 02J gearsets (stronger).
4) Peloquin LSD install while the gearsets are out/exposed.

However, having done a little more reading recently I think I should stick with standard 02A (gearsets) with LSD, it should hold up just fine in my application. No need to bother with 02J parts. Costs less this way too. The 02A may be found from the following vehicles: Passat 16V, Corrado G60, all MK3 VR6s, Corrado VR6, Passat VR6, and some MK3 TDIs. There are a number of 300-plus whp VR6Ts with 02As.

I haven't done full research on the entire tranny swap yet so there may be some flaws to my thinking. If I'm going for a full 02A then I won't have trouble finding one for cheap. The Peloquin LSD may be purchased from http://www.thescirocco.com.

[935racer]

Except the vr6 trannys don't bolt up cause they have a different bellhousing.

[malone]

Thanks for the reminder, will try to find 4cyl 02As.

I bought my Peloquin at thescirocco, Peter is a great guy to deal with..

OK, can someone tell me why Peloquins or Quaiffe's are so desired? I'm assuming that they are some sort of limited slip diff that can put more traction to the road, but Peloquin's site doesn't have much info on what his stuff actually does.

Read about the Quaife's benefits here:

The Peloquin is another brand of torque biasing differential, and it delivers all the benefits of the Quaife.

[dubCanuck1]

Perfect. Now I have to add that to the 1.5 year plan....

you can also get a clutch cable adapter for the 02a. a friend has one in his vr6turbo, it is a nice piece. im going to use one for my o2a swap. cost aboud 120 bux usa. its a european part so maybe u canadians could get it easier. worth the money instead of swapping over to a hydro clutch. and i like the feel of the cable.

for far less than 100 bucks you can get the "adaptor" you speak of to elminate the need to convert over to hydro clutch.... worldimpex.com ...i have the pn somewhere...

Its simply the clutch cable actuator from a eurovan ...cost was around 40 bucks I believe through them. From there...its getting the cable to fit...several ideas/ways to do this have been discussed on the VWVortex...I'll do some digging...i looked into this when I started the mTDI for the Rabbit...

[malone]

40-60 bucks for the 02A clutch cable adapter is not bad! Good info, thanks

A little update for those who are curious:

* The prechamber cups are being ceramic coated today.

* The piston protrusion was measured at .79mm, right in spec for a 1-hole headgasket. I was running a 3-hole headgasket.

* The cylinder walls look great from extra care, unlike my other two TDs

* The drained motor oil looks clean.

* 935racer's head deck mod appears to work well; there's a nice even burn over the pistons.

I mentioned a while ago that I had blue/white smoke below 2,000 RPM even after we tried pump timings from 0.90 to 1.10.  If I leave my glow plugs on (manual switch) the smoke was reduced significantly. Hopefully the precup and headgasket change will reduce the low RPM smoke for the time being.
