The T3200E thread

Comparing "mystery" plug on the wbx6 loom to one on a grotty hacked about 4-cyl loom.
Green/black wires are the same for both and its located in a similar area of the engine bay, so its defo coil/tacho supply but...the latter isn't the same as any of my DJ looms, so is it an MV loom detail?

Thanks to Aidan Talbot, Bentley and a couple of long phone conversations, I now find that the lambda goes to pin 5 on the ecu plug (it was the only plug aperture showing signs of distress anyway)
This makes it the "same" as the early EY 1.9 EFI ecu circa 1983, which was also a Digijet + lambda system...

Head "porting" work, mostly blending out the throat area behind the seats and eliminating steps to improve flow.

While this one is in bits I was comparing the dipstick low/high marks to a 4-pot and I was alarmed at how low these engines run the oil in comparison!
(I have since been told that there may have been an ulterior motive for this...)
First two pics: Mid-level on a 4-pot sits around the bottom of the tappet bosses and this is where most wbx seem to naturally stabilize the oil level anyway (anecdotally at least)
Note that the low notch on the dipstick is well above the top of the oil filling tube drilling and just visible.
Pics 3 to 5: See how that compares to the low level on this wbx6 dipstick? Its a lot lower, in fact the 6's high oil level is lower than the 4's low mark!
I am considering moving the dipstick to the usual wbx location, but drilled near-vertically so that it checks the oil level via the cam wheel housing. The dipstick will need shortening a tad.
Looks feasable and less leak-prone than the drilling in the filling tube boss?
(The reason for the dipstick being relocated on wbx6 is because the tappet bores/spacing were changed, so the drilling would have passed right through #3 exhaust tappet!)

Interesting stuff, but you can't just say there was an ulterior motive and then not share it ....

I know of engine type which suffered from some issues which I was looking into recently, there was a mod which consisted entirely of a shorter dipstick.

You show me yours

Ulterior motive possibility: apparently a replacement 3.7 engine in 1995 was priced at 45,000 DM

That was knocking on £20k at the time!

If they wore out prematurely, so what? Sufficiently well-heeled patrons and all that...

Ah yes, just a go faster upgrade, no need to worry about the value then.

The engine I was researching was from a Saab 9-5, V6 3.0 Tid. Not Swedish, from an Isuzu apparently

Laying in a few parts...

Now I know I didn't use my toes but you don't quite seem to have enough to do two 3200E's there

I'll never be doing another wbx6 after this one!
The other four are for the last "blueprint" DJ I'll be building (only got one original cam left)
Bought a couple of new JP breather towers for the 3.2 and the 2.5 as well, they are absolutely spot on.

Tight a*** VW! I falsely assumed that the pistons came with pins...another special order to BW for those, along with genuine barrels, rings, valves...
If you're going to do it, do it right.

So when you add the rings, pin and circlips, those pistons come out at £160 a piece? Good grief! Cheaper to have them made...
I just bought a set of these KS ones for about a third of the price.

I was offered some pretty keen pricing and I wanted to do the best job possible.

For comparison, the 98mm parts it works out at about £240+ vat per cylinder (piston, pin, rings, liner) but only if I buy 24 at a time...

I have had custom pistons made by JE in the US, 104mm bore for a turbo engine, works out about £500 for four, includes pins and circlips, piston rings are specified differently depending on the bore material / coating.

The guy I order through is here in the UK and has the machinery to scan pistons then modify the design if you wish. He also gasflows heads.

I buy 5 at a time - four for the motor, one just in case a custom piston goes bang. Never has.

Interested ?
