Lightbulb T5 Oxy-Boxer

Anyone on here running or building a T5 Oxy-Boxer?

After pulling a 2.1 MV engine I just see so much potential, but few details are out there on what exactly needs done to make it work.

The real hurdle I see it machining the 94s to fit the WBX case. Everything else is normal details.

Also I do not plan on relocating the head studs. The holes are for 10mm studs but it is stepped to a 8mm head stud. My plan is to put in "case savers" to essentially bush the 10mm to an 8mm and use those studs with some mods since it needs cut .5" anyway. Then bore the head hole out a little and the cylinder holes out a little and then you are in business. The studs are not that different really.

The hard part in the states is getting T5 bearings

... FWIW you all can count on a yard sale of all my T4 stuff if this works out. Give me a month

im not actually planning an oxyboxer like that, but i will be using a counterweighted 76.4mm WBX crank and rods, but inside a type1 case! reasons being, machining is less complicated, and an oil cooler can be used inside the shroud. i also have a lot of type1 parts that i can still use on this engine when its built which i would have to sell on if i used the T25 case.

im already using part of the engine i raided though... the ignition! WBX ignition on a type1 motor is great!! the whole dissy, coil, module and loom just swaps straight over!

Bren sounds good. Be careful on the rods though as they have 24mm pins and not the 22mm pins like standard VW T1s.

This is probably a long term project for me, unless it is too easy to pass up... But we will see. Having a DMS 78.4 T1 stroker sitting on the shelf is really making me waffle on which way is easier and cheap. As I already paid for the T1 crank.

Yah the Vangon ignition is a good thing to swap over if you can find it.

Take Care,

Just got some machining info and this conversion is amazingly thrifty if you plan on a basic build... In any build there are constant costs which really do not change no matter how big or small the engine is.

So getting the 94Bs machined for the T5 case is $150.

Case savers to go 10mm in the case to 8mm studs. $30-50 worst case.

... Evertyhing else is a constant!

The most difficult part will be getting the 2.1 mains from Europe... Might have to call in a favor from one of our European buddies or suppliers here ... Or if the bearings are perfect reuse them, slim chance but possible.

So essentially for less than the cost of a custom counterweighted T1 crank you can be rolling in a T5 conversion!

More to come....

Also consider the lack of machining costs to the T1 case when going bigger. Cut case bores for cylinders, clearance, tap for full-flow, maybe allign bore... blah blah blah

The T5 case in contrast is ready to go as is. Just cut the water jackets off.

Thanks Jim! That is excellent news! You do not realise how big the smile on my face is rigth now I was very worried about this issue. (A USA VW problem I think)


Zen, Yup. Pretty soon as long as I see this T5 thing working all my T4 stuff is up for grabs. Probably just post it in the FS area in a month or so. Granted I do not think I have that much great stuff hiding in my basement laboratory. Most of the treasure is just a huge pile of good T4 German tinware... Stock piling for Cali conversions.

Again I will keep you all posted on how this is working out as I progress. Maybe post some pics as well.

I like what I'm seeing. What kind of HP do you think you can get from the 2.1?

As for power I am going for around 100. Which is essentially stock.

I know lame, but it is for a '66 Bus and I am focusing on the CIS fuel injection and hydro lifters with stock cam. So I do not see much power added at all. I need the displacement for torque over big HP.

Now if this were going into a Beetle... I bet we could see 150+HP pretty easy, but the price goes up. 4" Autocraft P&Cs with custom drilled street elliminator heads. 84 crank welded and C/W WBX crank, chevy rods journals... The front wheels may never touch the ground again Easy displacement, but gets expensive fast. I imagine I will just build a mild 2.1 for the Beetle in the future anyway, granted lumpy cam and great heads still around 140-160HP.

... I would be very affraid of anything over 160-170 in a Beetle anyway... Almost undriveable because of the brutal power to weight issue. A lot of people want huge HP, but to me it is overkill. Granted 125-150 is about right.

Thumbs up

Hi I'm Type 5 Joe (joe of centorg on the STF)

Pillow contacted me and told me I should be on here, so here I am!

These Type 5's truly do give you your best bang for the buck!

I think Pillow will decide to re-locate the 8mm studs, we'll see....

You can stuff alot more stroke in one of these than a Type IV, for way less $$$

I do custom ACVW machine work on Type I and Type 5's (Oxyboxers)

If your interested in this conversion you can E-mail me at (use underscores for the spaces):

accu_tech_inc@yahoo.com

I charge $500.00 + shipping to Jet-spray clean the case, Mill the water jackets off , re-locate the 8mm studs, drill and tap all oil passages (includes brass pipe-plugs).

Modify new Set of 94's $150.00

Sleeve lifter bores to Type I size W/ 7075 Aluminum slugs $150.00

Six case hardened Bullet nosed Shuffle Pins $100.00

Cylinder head work too.

Glad to have you here Joe! Your input will be greatly appreciated.

Especially since you are the only T5 machine guy in the states that I know of. I still encourage you to start a vendor forum to get the word out on this new option for air-cooling. I am sure you can work with Alex on this.

Take Care,

Welcome Joe!

Joe is one of the very few people in U.S. who is involved in the wasser/oxy boxer engines.He is knowing what he is doing at all...
Excellent machine work!

Rgds,
