What does it matter? How many people actually drove their 94 bore motors to Vegas, Phoenix, Sacto, etc...?
I did Vegas four times and Sacto once with my old 94 bore motor, Phoenix never because I don't like Arizona. Point is, it will come around and it probably won't be too far off- I guess 250hp on California pump gas at low rpm through IDA's driving non-stop for an hour and a half through 100+ degree heat and stop and go traffic isn't enough reason for people to start building...
For me, a true street car can go anywhere, anytime.

Zach
Jeff drove his to vegas and back under the strict Real street rules with the rest of the guys,filling up with pump gas along with everyone else,running it hard at the track then driving home again,thats good enough for me,I have 2 pairs of angle flows sitting here waiting for Jeff to get some time to work on them

Not long ago I purchased a set of vintage 100mm Empi Birals. They were originally designed for the 914/T IV Engine. I was contemplating building a type 1 engine with these, but I'm not sure if they will work because the cylinders are 3/8-1/2in
shorter
than a type 1 cylinder. I think the added deck to the Alum case could make it all work out, what do you guys think??
I think type 4 cylinders belong onto a type 4 engine
(less hassle, costs etc. in the long run for you)
-> you better sell those to me

I keep reading about the 4" motors. and i admire the effort to get a 4" bore in at T1 case. Jeff's 'street' 3ltr motor was awesome!, but isn't it just easier and may be cheeper to get a scat killer case, Autocraft or a Pauter case that already accommodates a 4"bore motor?
maybe I'm missing something, but the above case arnt that expensive are they? and if there made to do it out of the packet then i think i'd lean towards that If you go down the Pauter route then you can get up to 3.5 ltrs.
just my thoughts.

hello martin. that would be to easy. this engine is closer to the type 1 platform wich i think anyone could have respect for. not that i dont have respect for the other aftermarket platforms. and you said somthing about 3.5l. im working on that slowley but surly. this is not the case im using just mock up junk block. just testing. it will become reality just takes time.

the goal is to get it out there and affordable and hopefully make it easy as possible for the average person to purchase 4inbore like it was a 94 bore.

The magazines need to do an article about this subject if the guys that are developing the parts / process / know how to do it are willing. Maybe they have already but i don't remember seeing an article on this in any of the VW mags. Then again, why should the guys doing all the R&D and hard work give their secrets away? This is cool stuff to see someone moving forward with this.

Just checked a wasserboxer-case today. Measured the holes in the case for the cylinders in a hurry to 100.17 mm.
When going to 101.6 cylinder bore, you have to make the holes bigger. What are the outside dia. on the cylinders from ex. AA or simulare?
Have some Magirus cylinders and they are 110mm outside. Want to keep as much material as possible in the case around the headstuds for strength, and the same for the cylinders.
Is it ok to leave the lower parts of the cylinderwalls 2 or 3 mm. thick?
That will give a total of 101.6 + 2+2=105.6mm. Machining the case 106mm.... hmmmmm?

As for turning the cylinders down, in T1 world is common to turn 94mm cylinders to fit into the case opened for 90.5/92mm cylinders exactly for the same reason to keep more meat around head studs. I have these cylinders on my 2276 and they are paper thin where they enter the case.

On regular 94mm type 1 cylinders they are approx 1.5mm thick at the bottom where it slides into the case,but you can get away with thinner as they are machined down more to fit into a case bored for 90.5 cylinders,all it does is support the piston at bdc

The AA Performance cylinders I used for Bang's oxyboxer drag race engine (101,6x86mm)
was turned down to 104,5 mm at the bottom end. So that's close to the same
wall thickness as Cima/Mahle 94 mm cyl set. I choose not to open the case spigot
bore more because I felt the bore was close enough to the head stud threads.
