hey guys cant giles build this guy a strong stocker style pump tho???

i was definately hooked after seein that extreme 4x4 show with that lil suzuki..it had a nice fuel lope...when i get back on the 79,ill def have him tweak mine

Definitely x2 on that suggestion, but I'd be worried about international turnaround times and shipping charges.  You know, seeing as he lives Britainland and all?  But if he can incur any of that potential red tape then yeah, definitely call Giles!

[Alcaid]

I think so? As people use them on the 4 cylinder TDI's.. and they turn the same way as the 2.4 I am assuming?

The 2.4 pumps turn the other way than our IDI and TDIs.... Don't think you can use a piston from a pump that's meant to turn the "normal" way in those D24T pumps.

[8v-of-fury]

You might just have to rework your injection lines is all.

[theman53]

I was thinking the piston didn't care it was the camplate that didn't like the reversing of rotation. I am not sure, but I would think you could definately get the pump to work but it may not be bolt on and go.

You'd need an opposite rotating cam plate, and to rearrange the injection lines, should work id think

[R.O.R-2.0]

Does the 6BT pumps turn the same way as the D24T pumps?

no, the D20, and D24 both have CCW rotating pumps..

they are driven from the BACK of the cam, not the crank.. these engines have a timing belt for the can and water pump, and a separate one driving the pump..

the pumps face the firewall on these engines, and need to spin backwards because of it..

[ian2000t]

Didn't realise I'd had that many responses, thanks all!

To answer a few questions, yes the pump on mine faces the bulkhead (firewall if you like  ) and run off the rear of the cam - do the 1.6 IDI's run from the front of the cam then? And mine does have an intercooler, but I'm not really sure how efficient it is, as it is sandwiched between (literally touching) the coolant and the aircon radiators, so it's always very warm! And, last year I did the cambelt, pumpbelt and headgasket - I used a 2 notch Ajusa MLS gasket rather than the fibre type, but I used new headbolts (12mm TTY) - the studs were a bit out of my pricerange last year.

The turbo on mine at the moment is a T3, I think the numbers are - 072145703 - 466794-1 - if they mean anything to anyone on here? I've also heard .36 A/R mentioned, but I'm a novice when it comes to turbos..! At the moment it's set to 16psi using a ball and spring MBC. I'm sure I have a boost leak somewhere though, at about 7-8psi I can hear a high pitched whine over the usual turbo hiss. It's been lie it for over a year now, and I've never traced it. In that time it's had new inlet manifold (D24tic reaplced for D24 N/A) and I used gasket sealant to ensure it can't be leaking; different boost hoses/pipes (had to be re-routed for inlet manifold); and I even tried bypassing the intercooler; but the whine is still there! Could it be the turbo itself?

What would be involved in fitting the HE221W? Would it spool earlier/later than my current one?

[Alcaid]

The HE221W has a T3 flange, just like you original turbo, so it's plug and play on your exhaust manifold. Depending on which of them you get, timing the housings might be needed but that's easy

These turbos run close to 30psi in stock form and are built to handle it!

Spool-up will probably be faster or similar to the turbo you already run while it has enough reserves to support effects way north of 200bhp (280-290bhp on 2.5TDI dyno proven)

Off course, there will be a need to fabricate or modify your existing downpipe, TIP, oil feed and drain and connect the turbo to the intercooler piping in some way.

[ian2000t]

Ok, well downpipe not too much problem, I know a few guys that could weld a new flange on my old downpipe, providing I can get hold of the right flange.

Connecting turbo to intercooler piping is fine, I've actually been considering a new intercooler, mounted further forward, and if possible with same side in/out to make pipework routing easier.

What do you mean by "TIP"? Oil feed and drain shouldn't be too much hassle I assume?

What psi would be sensible to run on this turbo on my engine, bearing in mind it's an Auto (ZF22) and a daily driver? Would this turbo still be a good choice if I only wanted to run 20psi?

At the moment it's very sluggish below 2000rpm, and the turbo starts to spool (5psi ish) by 2300-ish, then is on 16psi by about 2600.

[Alcaid]

TIP = turbo intake pipe

Sounds like your turbo is working well for  a stock unit.  Are you nozzles in good shape?  Timing on the advanced side of spec?  A little more off-boost fueling might wake it up quite a bit too.
The original intercooler is very good as stock ones go,but the bigger chinabay ones fit pretty easy too.
 I think changing to 3" exhaust helped my spool time a little.
My Aside from the stick transmission and no intercooler, my setup is pretty much like yours, and I stopped at about 1 BAR due to EGT.
IMO, the stick cars feel faster.

Extra fueling, faster spooling

Mistake on my behalf! The HE221W has in fact a T25 flange

[ian2000t]

Had a look, but Holset turbo's aren't easy to find in UK - not aware of any cars that use them!

My mate suggested a GT20 of some variety. How good a match would that be for mine, and which GT20 would I need to look for?
