thanks for coming

just a couple questions about the car in my sig, it has a 1973 or 1937 cc engine, cant remember which, and it seems to be mildly warmed over. is this a stock sized engine, or at least a common size?

it is running a small single barrel carby on it ATM, a solex, just wondering what aftermarket carbs people run on these, something for better performance wiothout sacrificing too much economy/driveability.

lucky its coming into summer, but how do the heaters work on these things?

and what are recommended guages to add into a beetle? I already have tacho, oil pressure and volts in mind, is an oil temp guage a good idea?

and lastly, WTF is the brake master cylinder? need to know this as the car needs the brakes bled after sitting around for a year or two.

any help greatly appreciated, thanks guys.

Hey Rota_Motor,no idea what size your engine is could be anything from 1300,1500,1600,1641,1776,1835,1916 with stock crank of 69mm,with different stroker cranks available too from 75mm up to 86mm,so yours could be anything.:o

oh yay, thats a comforting thought.

I'm pretty sure the guy we got it off said it was something in the vicinity of 1973cc I think, I might have to see if we can find some more details of the engine.

1971cc is the size of a stock 2lt type 4 motor. Do you know what a type 4 motor is? maybe that's what you have?

Can you read the engine number?

Does the exhaust bolt to the sides or the bottom of the cylinder heads?

Any chance of posting a pic?

thanks wes, I can call you wes right??

it apparently has single port heads, I can tell what they mean as the inlet manifold only bolts to one port each end (duh)

the exhaust ports are front and rear of the cylinder heads, and I can try to find an engine number next time I see the car.

and I have no idea, what is a type 4 motor? uhh what is a type 4?

I'll try to remember the camera and get some pics next time too.

thanks for the help guys.

could be it was a 1971cc... sounds about right.

a type 4 motor is from a kombi.

By your description you have a single port type 1 (from a beetle) motor. I really really doubt someone would build a stroker 1973cc motor and then use single port heads on it. I have a feeling that you have been taken for a ride. I think the engine would be lucky to be 1600cc, but hey, I could be wrong.

Yes you can call me Wes :thumb

so what's the performance like? A 1971cc motor (single port, single carb) should have heaps and heaps of low end torque, and absolutely no top end.

first... congrats on ya purchase.

second... yes get a temp guage. i remember when i first got a beetle and had pressure guages and such. but a temp guage is a good idea. better than cooking ya motor.

third... if you look under the car up behind where the pedals are you will see a brake master cylinder that is connected to the footwell wall. but you would be advised to check all your brake lines and brakes b4 bleeding, just to be sure that theyre all fine and no leaks.

heaters... if you have a worked motor as you suggest. you would have to look under the engine and take note how the exhaust feeds out from the heads. if you have what is called 'J' pipes, simply a pipe leading from the back of the head to the extractors at the front, then your exhaust will not work. if instead you have a fatter pipe and a tube heading of each pipe heading back to the rear of the cabin then you will have heaters. generally when you get a worked motor it is normal to just have j pipes as it is a more efficient flow of air.


as for carbies. i know of people who run two standard typ 3 carbies, off each side. but your best option for money would probably be some kadrons or if you keep an eye out on this site you could pick up some bargins.

hope i helped.

helped a heap twoguns, so you are saying the heaters work off the front exhaust pipes just heating the air up?

sounds like some customising to get a heater happening

and what are kadrons sorry but complete beetle newbie here.

yeah. the j pipe is a inner piece on the heat exchanger and the hot air was directed to teh cabin. this was how some went to sleep as the pipes would crack and allow fumes thru the heaters.

kadrons are a brand of carbies. i am putting them on the 1776 i am having built professionally by custom bugs and buses in penrith.

the best thing to do would be to upgrade from the single port heads to twin port heads. Then what carb's you run depends on your budget.

If you stick with single port you could go with a single twin throat weber.

If you go to dual port it really opens your options. kadrons are nice and cheap twin single throat carbs. If you want outright performance go for twin webers.

If I were you I'd pull the heads off and measure the bore and stroke. If you stick with the single port heads then just put new pushrod tube seals in and whack it back together. I'd upgrade to twin port heads though.

sounds like a 71x94 motor to me. Exactly the same dimensions as a type4. I've heard of these engines before but not in years.
Using worked single port heads and small carbys used to be really popular with the off road guys. It gives you bags of low end power, heaps of reliability and you don't have to worry about loose linkages that would often happen with twin carbys.
These set-ups (along with engine size) were popular probably around 20+ years ago when my old man had his baja. So it's possible, if the dude who built your engine was into the that sort of thing, could have been building what he knew worked.
As for getting some more power out of it. Maybe a turbo set-up? Get your heads off and have them checked first tho.

heh. thanks guys, but right now, the heads ARE NOT coming off

not with the VW thing, but wouldnt that mean a set of head gaskets etc.??

will need to find out exactly what was done to the motor, because we dont want to pull it apart anymore than we have to, was just after a little more go from whats there

VW motors don't have head gaskets.

A complete gasket kit for the vw was $20 last time I bought one (few years ago now). So it's not exactly expensive to do.

I think you need to buy a workshop manual, or the idiots guide manual. It will help you a lot :thumb

well, had a better look at the car today, if I can work out how to do it I will post pics.

it has 'j' pipes on it, but we have new extractors to go on, I'm guessing (hoping) we just use the cutrrent J pipes on it as therec were none supplied (new extractors supplied with car).

we can, as earlier asked read the engine number, took a pic of it but not clear, but we think it is 126-019142

and we got a workshop manual with it, I can see they dont have head gaskets, but it doesnt really details what does need to be done, although it is only for 1100,1200,1200a and 1300 models.

a pic of the engine bay

dammit

sorry for the now triple post, just trying to post a damn pic.

I very very much doubt that engine is anywhere near 1973cc. Maybe its a 1973 year engine.

This is the starting point for most people.

Should be able to get one at Vintage Vee Dub Supplies or somewhere like that

wow, I'm surprised this thread was dug up, anyways, if your reading thism, it does sound like cam said, it is a rocket off the line, but really runs out of breath pretty quickly.

twinport heads are already in the pipeline, just running the stock carb to start with, while I got the heads off, I will be taking a bore and stroke measurement to see what it is exactly.

i think eng no starting with with 126 are vw industral engs they came out single port 1600 i have a few industral engs and the eng no all start with 126

thanks vwking
it was really conmfusing me, the engine num,ber looks factory stamped, but every source I can find has car engines starting with a letter prefix, which we dont have.

so it probably started as an industrial 1600 SP but I'm pretty sure thats not what it is any more

its not a 1973 year engine amazer thats for sure....just looks like a 1600 single port to me
