I have a 1700 t4 and want to go big, stroker crank and bigger piston barrel kit plus all associated mods. Are there many differences between the 1700 and 2l case? I have a machinist mate so maching costs are not an issue, I just want to make sure I spend the time and money on the right base engine in the first place. I bought the 1700 thinking i was getting a 2l so all these mods were planned but now not sure if all such a good idea for the 1700? any info/comparisons on the engines would be much appreciated, I'm oldschool type 1 and 2 and am new to type 4's! cheers

I know a guy in Melbourne who is doing stroker kits for type 4's, I can pass his number on if you are interested in that.
From memory they are 2.6L.

If your going to that extent to upgrade, I can't see much difference whether you start with a 1.7, 1.8 or 2.0 motor.
The 3 versions of the motors had a number of differences, and all had their advantages. 2.0 was the largest capacity, but not neccesarily the best as they began to restrict the motor to meet tightening emision laws during the 70's.

There is a few more than 3 type 4 engine setups...
Letters are the prefix to your engine number
V 1700ccm 50kW/68HP
Z 1700ccm 50kW/68HP
EB 1700ccm 53kW/72HP
EA 1700ccm 59kW/80HP
W 1700ccm 59kW/80HP
CA 1700ccm 49kW/66HP
AT 1800ccm 55kW/75HP
EC 1800ccm 56kW/76HP
AN 1800ccm 63kW/86HP
AP 1800ccm 50kW/68HP
GB 2000ccm 74kW/100HP
CU 2000ccm 51kW/70HP
CV 2000ccm 51kW/70HP
GD 2000ccm 51kW/70HP
GE 2000ccm 51kW/70HP
CJ 2000ccm 53kW/70HP

It certainly wont matter with the amount of mods you are doing for the stroker engine.
The higher hp engines are from porsche 914's. They are good engines to start with due to the fact they have an easier life in the lighter car and less heat related issues.
I would be fitting brand new heads also...

I sent U2U with details too...

DO NOT use the 1700 magnesium case...your engine will fall to bits.Best to start with a 2L case in my opinion as they are at least newer cases.

The 1700 case was only magnesium in the very early 411's and were only found in Europe. I have 2 1700 cases and they are both aluminium. Also the 1700 case is the best to build on as all the clearances are spot on, where as the 2 litre case although still excellent has tiny variations in measurement. Why cause the 1700's were the first cases made so the factory ensured that they were spot on.

I have a 1700 magnesium case out of my early 411 and as I said above,don't use the mag cases for HP stuff!! My first choice for any HP Type 4 donk would still be the 2L case simply because they are newer than the 1700's. Any clearance issues,if any, would be resolved by the engine builder whilst machining everything....

Yep, my old mans '69 411 also has a magnesium case - I love the 411's ... way ahead of their time.

For a "simple" easy to build, long lasting big cubed T4 a 2.3L based on a 66mm crank is the go.
This has a 2:1 rod ratio with stock rods and all parts are cheap cheap

The "W" code 1700 is out of the 914, and is Aluminium. Also, the dipstick is on top, it's not machined for a mech. fuel pump, and there might be another difference in the case, but I can't remember what it is. It'll be minor, though.

Cheers mate, but I'm still not giving you any bits!!! :P
Damo, your welcome to a look at the case when you return if you like :thumb
Ratty 63, is your old man down your way? I'd love to compare 411's if he is!! Not so sure about the "ahead of their time" bit though, I've been collecting articles of the day, the 411 coped a flogging in motoring reports when released.

So split bus boy, you still building your motor?

Yep, lives about 5 mins from my place - I'm still trying to convince him to dig it out of the back of the garage and fire it back up - it's been in hibernation for years now. Used to be my Mums daily driver until the clutch slave cylinder began causing problems. Dad has owned it since 1971 (before I was born!) :duh

I try to get him to 'dig' it out - I'll let you know how it goes..

Why the 66mm crank and not the 71mm one Baz?

Because from "what i have been told from a fellow who has built heaps of these" it has the "sweet" 2:1 rod ratio

As per you comment in Tech stroking doesnt/ may not always work

The rod length of the 2L was based on making it fit rather than what was best for the motor design
