any way to put type 4 head on type 1 engine?

sinistervw · Post by **sinistervw** » Tue Jun 11, 2002 5:25 pm

i was wondering if its possible to put T-IV heads on a T-1 engine cause T-Iv heads cool better...would be for a 94mm bore Biral babie and a aircooled.net aluminum block. or is there anybody out there that makes a type 4 style head for type 1? sombody needs too if there isnt!

The simply answer is no! Now if cost and time mean nothing to you it probably can be done.

Hello-

oh and why cant i put type 4 heads on my type one...size or what?

Before you continue with the welder, get a T4 head. Then, sit it next to a T1 head. You'll find about a billion things stopping it from working, including:

-bore spacing
-valve covers (once the bore spacing is fixed)
-cylinder bore size (105mm is stock 1.8/2.0, which is bigger than the 101.5mm size used for T1 94mm cylinders)
-stud location (maybe you can fix it... good luck avoiding the rocker arms and associated goodies
-cylinder stud fitment
-cylinder spigot length (T1 is much longer... means more area w/o fins if T1 cylinders go on T4 heads)
-cylinder tin fitment
-intake manifold non-existence
-exhaust system non-existence
-pushrod tube fitment
-pushrod placement (i.e. it wants the lifters to be in different places than they actually are)

Well, there are probably more, but I can't think of them at the second.

Maybe you haven't torn apart a T4 before, but they are TOTALLY different than a T1. Very few parts can swap.

Yes, it is entirely possible to do what you describe. No, it is not easy and it will be very hard to justify the time and cost of doing it.

I wouldn't cross my fingers on someone making a downward-exiting exhaust port T1 head in the future, either. One large advantage to the T1 engine is the very cheap price and the absolute plethora of aftermarket crud lying about. These heads would eliminate both of those.

Why not just get a whole T4 engine and be done with it?

Take care,

"Why not just get a T4"?
I guess that 'might' be easier.

I'll agree with Shad, that T4's are awsome powerhouses, and I'd love to put one in my bus someday, but i'm like you, I like T1's in my bugs!

What's so special about being able to do 130mph while running cool anyway. LOL

Hey, to each their own!

Perhaps a bit more practical of a comparison is being able to pull up that long mountain grade in the desert on a summer day keeping up at 80mph with the rest of traffic

Check out Strickly German Auto's site????-I think is their name I'll check this soon but they put wasserboxer heads on type ones aren't the wasser heads like the t-4 or am I way off- sorry I am a t-1 fan and I am just starting to pay attention to t-4's and wassers and their potentials-just dumped a ton of money into two t-1 mtrs-kinda wish I could go back and build a aircooled wasser hybrid-ss

Build the TI correctly with some bad ass cylinders (nickies) and you won't have overheating problems..don't be led astray, this is NOT easy to do.

Hello-

Nope... you're "way off"

The wasser heads are much closer in design and dimension to T1 heads but with waterjackets. T4 heads are a whole 'nuther ballgame.

You really have to see and hold them to understand. Once you've held a T4 head in your hands and put it next to a T1 head, it'll never again be a question of why the T4 head cools better... they are MASSIVE compared to the T1 heads!

Take care,

I lost the link, but there's a site that shows how someone (I think he's here on STF) converts Wasserboxers to aircooled. Why? Stronger case and crank, or so he claims. Regardless, interesting as hell.

Question about the baby nickies Shad, you think that they're suitable for my 1915? I'll be running John C's Supersquishes, approc 9.5:1 CR, split duration cam, dual IDF's, AJ Sims heads with 42 X 37.5 valves, merged headers, blah blah blah. Thanks
