Great project. I'm following this thread closely, as I'm working on fabing a set of motorcycle throttle bodies to a type-4 engine. I'm new to VWs and maching aluminum. If you don't mind me asking, what tools did you use to fab the adapters? they look like works of art. what will it take for a novice, working out of his home garage, to be able to fabricate something like that? Thanks.

[GetBackOnTrack]

I bought the adaptors along with the terminator carbs. But you need a mill to fab a set, or you can send me some worksheeds and I will make you a set.

Got the time to make 8 shims with skirts for the valvespring to rest in. Cut off 0.5mm of the Gene berg ratainers aswell. This gives me 1,8 mm before coilbind at full lift 15,7mm. Hope this will last and not bread the springs.

BTW, have made an extra set of the shims with skirts if anybody needs.. They measure 0.9 mm thikness, 42mm OD, 17,1 ID, and they have a 3mm tall skirt to keep the spring in place at high revs..

Made myself some parts for my linkage today..

Also got the shortblock finnished.

Hardcore work. What cooling system are you building Jakob ? T1? , DTM ?

Why don't you cut down the seat of the springs ? I do this everytime i use Type1 springs. so you have space for more travel and the springs fit into the head

I think there is only about a couple of mm from the spring seat to the induction channel, God forbit that I would cut into the channel, so decided to remove a bit of the retainer instead.

Got a little ekstra material welded on above the induction channels and faced them afterwards in the milll..

Im using an old style fanhousing with the generator precise in the middle of the engine..

I like the ridge leading towards the valve guide! Not often you see that done to 4-bolt type 4 heads.
Nice job overall!

Type 1 springs are smaller and you can cut them down 2 mm with no breaking through

[GetBackOnTrack]

Thanks Udo.. Il keep that in mind..


A picture of the linkage im producing.

Linkage under construction.

[TSAF]

Very detailed work indeed. Let us know with the outcome!!

[bang]

nice work.

[GetBackOnTrack]

Thanks.. Ill keep the thread going until the engine hits the dyno...

A little tinware fabrication going on.

Regards.

[Harry/FDK]

Jakob, can you post the pictures in 800 x 600 resolution ? Youre work is far to beautiful to post them like this !!!

[volkskris]

Awesome work g bot

[GetBackOnTrack]

Got my last parts for my engine today.. 105 mm JE pistons, pauter 1.48 roller rockers.

Checked the deckheight and it was a bit too tight, 0.5 mm, so I cut off 0.5 mm of the pistons to accomplish 1 mm deck. Also had to cut 6 mm deep valvepockets int the pistons.

Another couple of days of work and im ready to put it all together 

Regards..

[GetBackOnTrack]

Also finnished my home made linkage..

[bang]

sweet.. looks like you will need my race gearbox for the summer..

[Harry/FDK]

Jakob, you have PM.

[GetBackOnTrack]

engine assembled and put in my car.. Just need the header now and a few other things, and im ready for start up

PM back to you Harry.

Regards, Jakob

[Harry/FDK]

Jakob, wich fan are you going to be using...T1 ?? I have a plan for a modified T3 fanring to T1 hub in my head. Do you breathe the case on #1 and #3 to "equilize" the breathing in the case #2 and #4 "chambers" ??

Regards, Harry

PS, i like the old style Fanshroud.

[GetBackOnTrack]

Im using a welded and ballanced type 1 fan.

The only breathing on the motor I have is the 1" at the flywheel end and a 3/8" at the crank pulley end.. Have done it that way on a few motors, seems to work fine.

Regards, Jakob

[Harry/FDK]

Hi Jakob, any news ? Are going dry-sump system ?

[fish]

Jakob, great work.
I'm following this thread with much interest.

Smart stuff, whats the centre mount fan shroud like cooling wise?

[GetBackOnTrack]

Hey guys..

Project is standing still at the moment.. waiting for a header, decided to buy one instead of building it myself..

Im going drysump on the engine yes..

The center fan shroud isnt the best cooling wise, but the car is not build for left lane cruising anyway... I use the car on the strip and for breaking up a bit of detroit iron every now and then

The center fan shroud is compact and gives a lot of room on each side of the carburetors.

Hoping to have my header soon so I can crank that thing and hear what she has to say to me

By the way, I need some distributor wires with some sort of bend.. I cant fit my msd wires in cause of the huge weldings around the manifolds.. Anybody know if msd or somebody else sells wires with a bend?
