I'm planning on making a 1600tp from mainly new bits...

I already have a pair of new stock 1600 heads, a pair of Weber ICTs, alternator, and 2 broken 1300 engines.

I was going to buy new:

AS41 Crankcase
Reground stock crank
All new bearings
Engle 110 cam
Followers
Barrels and Pistons
Oil cooler
Push rod tubes and seals
Gaskets etc

Is there anything else? Apart from clutch/flywheel.

I would re-use one my case from the 1300tp (AB) but after machining and checking it would be probably be over half the price of a new one?

This is for a daily bug, does this setup seem sensible?

Hi,
I think your choice of cam maybe a bit too hot for those carbs, heads and the 1600cc, with that spec i'd go for an Engle 100.

I'm building a 1641 which you might consider if you are going to buy barrels and pistons. If you can find a good used crankcase (on vzi?) you could use the money you save to up the spec? Use VeeDub Performance Parts in the US and you'll save a packet even after import taxes.

The spec on my engine is:
Flywheel lightened to 9 lbs then dynamically balanced to stock crank, 5 lb front pulley, clutch plate and pressure plate, 8 dowel'd crank to flywheel, Rods match weighted and balanced end to end and little ends re bushed (within 1 gramm tolerance)

1641cc Pistons matched weighted (within 1 gramm)
Engle 110 cam, new lifters and chrome molly push rods
Full flowed crankcase and external oil filter and cooler.
Straight cut racing cam gear set
Windage tray
New bearings throughout
CB sport heads with 40mm intake & 35mm exhaust, dual valve springs and titanium retainers, 3 angle valve seats
Dual twin choke 36mm IDF Weber (Alfa Sud) carbs and manifold matched to heads
Collector header exhaust and racing muffler
Bosch Pertronics ignition and racing coil and leads (breakerless points)


I'm hoping for about 100 bhp from this little engine

Hope this helps??

Regards

Mart

How about a new H/D oil pump, or even just a new stock oil pump. But a new oil pimp all the same.
Yup forgot about that, am I right in thinking there is a pump that has a takeoff plate for full flowing without the need to drill+tap the case?

Mart- Thanks for the info, I may have meant the engle 100, I don't want anything too mad as I want it nice and driveable low down as it won't be going above 5000rpm. I was going to match port the heads.

I keep changing my mind about my case. I have a AB code AS41 case which I've stripped from a previously reconned engine. The main bearing saddles have 3 bands of 'colour' on them, matt on the outsides and a shiny band in the middle, I can feel a slight ridge with my fingernail. Perhaps I should just get the case line-bored? The crankshaft has been ground to use +0.25 bearings and has ridges present as well. The middle journal bearing had started to break up so I would expect wear on the journal.

I was going to get a reground (possibly exchange) crank from a shop as this seems the most cost effective.

What do ya think?

Cheers, James

Hi James,

I've read if you can feel a ridge on the case bearing saddles then you'll need to get the case line bored. My case has been line bored and used since but I didn't find a ridge upon stripdown so I'm re-using it.

I have seen a full flow kit that uses the normal oil pump take off (you need to block the pump outlet by fitting a plug either in the pump or the case or both) and then the return goes into the oil pressure relief valve which you get a special unit to replace. I don't know if they are any good. Also you can get an oil filter cover that has a side mount filter but this places the filter next to the exhuast and isn't too good.

Hope this helps

Regards
Martin

I thought so, does anyone know what I should expect to pay for a line bore and what the increments of material removed should be?

The only machine shop I've have experience with is a non-vw one in Elstow, near Bedford, T and L Engineering who rebuilt my Dad's Jowett flat four.

Does any one know of any who specialise in VWs in the Herts/Cambs/Beds/Essex area?

Cheers, James
