Need Help with an Engine Build

[rwalker1296]

I've been away from the VW scene for sometime and just got back into it now that my son is turing 16 shortly and loves VW's.
The last engine I had built years ago for my car was a 1835 with Street Eltiminators, VZ 35 and 48 IDA's. I don't want to do that again, going more reliable this time.

I'm building a 1776 or larger if you can educate me, but want to stay with the 69mm stroke because I already have GB crank and flywheel from my old engine. It's 23 years old, but not damaged.

I have a new pair of Kadron 40's and my questions is what cam and heads to buy. It's all changed so much in the last 20 years that I'm a bit lost.

My engine builder is saying that the CB 044's are pretty nice for the money, but I'm leaning more in the direction of the Los Panchito's due to the smaller valves and less worry about cracking between them.

He is also steering me in the direction of a 110 cam, but with the heads that I'm looking at I think I could go with at least a 120?

The car is going to be driven in the summer only and is not a daily driver by any means. I may take it on some 250 mile trips to our cabin this summer and that's about it. I'm looking for the most power along with the most reliability. I don't have bugdet restictions, so please let me know if I'm way off base here.

Thank you for any help.

I'm old school so I'd go for the 1835 but build it with the thick wall 92mm P/C from AA. You don't say what "car" this is going in so I'll assume a Beetle. 94mm P/C's will work well too and give you 1915cc. If it's going in a Bus or Type 3 then I'd stay with TW 92's, but that's just me.

Heads, definitely 40 x 35.5mm P&P. Something like Steve Tims Stage 1's or DRD/AC.Net L5 heads would be great in this application.

...............and then there's Chong Woo, The Man, The Myth.

If you want to use Kadrons then stay with the W110 cam but I think for what you want the W120 cam would really suit you better with Weber 40IDF's or Dellorto 40DRLA's.

A 1 1/2" header will do for exhaust.

Thank you for the input!

The engine is going in a 1963 Bug. Sorry about that.

I would go for an 1835 or 1915. Stay with a 110 cam. You will be happy and reliable. Full flow the case for oil will also help make it more reliable andlast longer.

Depends which 110 cam he is refering too, the Engle W110 in a 1916cc would be quite mild, the Web Cam 110 is closer to the Engle W120 and would really waken the engine up with the other components you are considering

If your going to stay with the dual Kads, I would build a 1776 with L3 stock valve ported heads and dual springs from Aircooled.net. CB 044 heads are OK but the L3's are a much better dollar value. I don't think dual Kads are big enough to support larger valve heads. An Engle W-110 cam would be a great choice. For a 16 year old I'd install a 5800-6000 RPM rev limiter to be safe.

For a little more zip then build a 1835 or 1915 with dual Weber IDF's and 40x35.5 heads. A W-120 cam would be a good choice with the stock 4.37 R&P in the 63 transaxle.

Thanks for the help guys!

I just got off the phone with my engine builder and here's what we're doing.

1914, L5's, Engle 120 and 44's.

He said this will have plenty of power and be reliable.

I hope he's right!

Use some 1.25 rockers to get your money's worth out of the ported heads; otherwise you're not getting the full benefit of the porting work. Might as well not spend so much money on heads if you're not going to utilize their full potential...

Thank you again for all the input.

With the V8's in my boat it was easy, just buy 496's throw on aluminum heads, blower cam and whipple efi superchargers and call it good.

Searching for the right combination for a VW engine is frustrating, and it seems the more you read the more you second guess yourself!

so much depends on your budget, which you have not stated.

Some people can "afford" $500, others $7k. Obviously those 2 recipes are different.

One last question and then I'll quit bugging you.

I've read conficting stories about what distributor to use. I have the brand new vacum advance distributor out of my car, or should I use something else and are the 44's set up to use a vacum advance distributor? Either way I don't want points to mess with.


Thanks again.

[DarthWeber]

For your application the Bosch 010 would be best IMHO.

My 1915 has a 120 cam with Los Panchinto heads, dual springs with 1.25's, 9:1 compression, 44 webers,1/58 merged header. Revs to 7000 and runs 8.9 in the 1/8. Had 1.1 rockers on at first and the 1.25's dropped 3 tenths off my time. It's a daily driver '69 beetle and has been very reliable since I built it 14 months ago.(except for some oil leaks)

[rwalker1296]

After learning that new cranks cost the same from CB I've gone a different way, not too different, but a little.

I've gone with a 74X94 combo, which I think is a 2056 instead of 69X94. I talked to Steve Tims heads today and they said the Stage 1's probably wouldn't work too good with the engle 120, 1.25's and 44's and recomended Stage 2's but I'm going to give it a shot and see what happens.

My questions is, what length rod do I need to get, do I need the A or B pistons and do I need a lightened flywheel?


Thanks again for all the help, you all have made this much easier.
