oxyboxer parts

Hi Diederick,

Of course you are welcome here. Jesper Danborn is probably the guy you need to talk to. How ever he is on his way to Bug Run in Sweden now, so have patience he'll be bak to assist you after this weekend.

do many people on this forum have oxyboxers by the way??

do you guys perhaps have some specs for me?

thanks,
Diederick

cool duus!

i checked out your project yesterday, it looks very very neat! 8)

yeah, i was wondering what specific parts you're using for the engine, so i can see what i need. like a second opinion next to VWMorten's parts.

what do you use for cooling? a porsche fan or sth else?

wicked duus, thanks! 8)

you're helping me big time!!

do i really need to machine the 94mm cylinders like morten did on his site?

cheers!

There is two types of wbx cases, the early ones with the number 025xxxxxx and the late ones with 025xxxxxxB written on the side of the sump.

If you got a early case, then you must get a adapter bearing like the one Rocky makes. This i quite hard since he does not sell them onless you buy a complete block!

If you have a late case it is much more simple. You need a set of wbx bearings and a set of T1 line bore bearing with .040 1mm o/s od. with a 1mm .040 o/s thrust. You use the T1 1mm line/thurst flywheel barring and the rest of the barrings are WBX and then assemble as you would a T1!
To make the flywheel oil seal fit i think you would have to make a spacer/bushing.

yes if you want to go with ultralight lifters you should use the T4 sleeves. If you are going to run a very mild cam you could just go with std. T4 lifters...

I don't think you can get around cutting the cilinders unless you plan on running CR 1:3 :o

I'd cut the waterjackets with a hand held grinder, and them machined them. You don't have to do the machining, i did it just for the sweet look.

There will probably be more machining to do, but it depends on how you want engine... Which cam, crank, lifters and cylinders will you be using?

To get 120 hp I would go with a wbx 76mm crank(if you can find one),94mm cylinders, std. conrods or I-beams, 044 35x40 heads, a mild web cam with std. solid T4 lifters, Dual 40mm carbs.
By using stock crank and T4 lifters you keep machining to a minimum.

You could swap the 94mm cylinders with 90,5mm... a lot of people consider the 90,5mm better for high mileage - but then you have to buy/make adaptor rings...

Duus

Of course you can get 150hp... It just depends on your budget 8O
You can get lots of good info about which parts to use at http://www.shoptalkforums.com/viewforum.php?f=15&sid=b512e1ea7b395c7db826ec7b89dd9589

And about the gas mileage, you'll tell me when it is done!(I have no idea)

[quote:ad14bd8c98="Anonymous"]how about:

Duus, how did you machine the last part of the waterjackets cos it looks great?!
Do i need to clean the case after grinding because a lot of metal goes into the case right? how do i do this? or should i use tape before grinding?

cheers!!!! 8)[/quote:ad14bd8c98]

Before cutting the waterjackets you should clean the two parts of the case perfectly... when you're done with the machining you'll just wash all chips off. Be sure that you dont get chips in the oil channels to lifters and cam/crank bearings.
I did the machining on a milling machine - If you have acces to one it is rather easy.

I would use a 1 5/8" merged header.
I dont know if a w120 would work with solid T4 lifters. You could ask Farmer(or wait for him to answer)...

[quote:875cea1757="Anonymous"]how about:

76mm reground WBX crankshaft with I beam 5.4 rods
standard WBX bearings (??) and stock 215mm type 4 flywheel
Mahle 94mm pistons and cylinders (gotta get them machined somehow :roll: )
Engle 120 cam with standard T4 lifters and SCAT aluminium push rods
044 heads with 40mm and 37.5mm valves (i'll do the porting following Morten's guide
009 distributor
40 mm Dell'orto carbs
type 1 fanshroud (what kind to make it fit??)
what exhaust?? 1 1/2 or 1 5/8?
and everything i forget (tell me if i forgot vital elements :o

this leaves me with the following machining on the case:
- removing waterjackets (using a handheld grinder)
- relocating headstuds (how much does this cost??)

Duus, how did you machine the last part of the waterjackets cos it looks great?!
Do i need to clean the case after grinding because a lot of metal goes into the case right? how do i do this? or should i use tape before grinding?

you can try to call me i can help you with questions

[quote:7f192f1725="Anonymous"]unfortunately i live in the Netherlands...

do you see anything wrong about the specs? or the lifters? please tell me over the forum or email me at died_zeel@hotmail.com

Duus, since i need to get those headstuds done professionally, perhaps i also get those lifter things bushed or something. i guess type 1 racing lifters are safer in the end, right?

p.s. please answer the question about the cleaning as well :roll:[/quote:7f192f1725]

I think that the w120 with 1:1,25 rockers would be too hard for the std. T4 lifters to handle - but you really should get somebody with more knowledge to answer this... http://www.shoptalkforums.com/viewtopic.php?t=84075

About the cleaning just buy some engine/carb cleaner liquid. The diesel may also work, but I havent tried it. http://www.shoptalkforums.com/viewtopic.php?t=77948&postdays=0&postorder=asc&highlight=cleaning&start=15

I use scat T1 slr lube a lobe lifters 8O

You can also get T4 lifters which have been slr coated, but I dont have the knowledge to tell you which cams they would work with.
Farmer once told me that if i wanted good power and still keep the T4 lifters, a good choice would be slr T4 lifters with a web 163(between w110 and w120) - I would go with that combo if I had kept the T4 lifters.

Because of the higher lift(web 86b) and the thickness of the "lifterhead" I machine the case to the right cam/lifter clearences.

You can get them at: http://www.aircooled.net/new-bin/viewproductdetail.php?keyword2=ECV0015&cartid=0616200562626893

I dont think that the T4 slr and w120 combo would require machining.
