Type 1 or Type 4 engine in a Bug?

You can use upright (T1 type) tin on a T4 and there are a couple makers of aftermarket upright systems for the T4. Go on back to Raby's pages and check out the upright cooling systems, and check Jo Cali's book on the subject.

Good luck! I'd sure like one myself.

Thanks for all your input, I have also run into the flywheel question, and that is the reason I am wondering if the bus trans would fit the Bug, and also, hopefully, be geared the same, this would solve any flywheel considerations. As for heat, well, I guess I should look at the bus engine again, I thought it had heat exchangers on the manifolds, maybe I could make them, as my car is a daily driver. It appears so far, through reading about this subject, that the type four has many of the upgrades we all need to consider when building a type one engine. The driveline I'm considering converting into my bug is a 1972 Bus, type four 1.7 litre, I now know the 2.0 litre is what others are using, however, this one runs, I have next to no money in it, it already has a pair of low mile Webber 40mm IDF's on it, it is a hundred cc's bigger than my 1.6 litre single port. It also appears that I can use this engine without hacking up my car to fit, only the cooling tin from my type one will have to be cut, fitted, welded, if I end up going with an upright cooling system. I'm really starting to think I may go ahead with this project, even though I've been advised a 1776cc type one would perform just as well. At this point, my car has been off the road for seven weeks, I have stripped the entire car to bare steel, repaired all dents, and am now in the blocking process, the suspension is reconditioned and lowered, and after all this body work, I know I have a tired engine with quite a bit of crankshaft end play, so obviously I need to make a choice, or maybe I already did.

Hi Doug, I was on vacation in Cape Cod, Mass. or would have answered your post sooner. Weird, it gets real cold up there and a mean salt air yet I have never seen so many buses!! Anyway. The T-4 scoop. Very simple things you can do. One is to just rebuild the1.7 and it will feel like a 2.0 T-1, the only difference is it will last 3 times as long. The best is to just get a set of 2.0 pistons and cylinders. They will fit right into the block. The heads will have to be opened up to accept them, which is no big deal, especially if you are going to do a valve job anyway. If you are splitting the case then for sure get a mild cam ( when ready we will talk on the right grind ). With that setup you will be pushing anywhere from 100 to 125hp!! As for the Flywheel, -- you got it already!!! The bus flywheel will work on the T-1 trans. with it's pressure plate. It is 210 or 215mm which really are big on holding power. You can even use a T-1 discs if you wish. But they are not as large, yet will work. Now the Trans, your trans will have the engine at 3000 rpm at 60 mph. My advice is to get a 73 or later trans. They have a taller 4th gear and will drop your rpms by 800. The engine will be so quiet. T-4 of that size will cruise at 75mph all day and blast to over 100 mph in seconds. By the way the reason T-1's are used for racing is they rev faster then T-4's yet you will soon see some T-4 drag cars. In no way are they slow off the line for regular street use. I look at an engine like the one you are thinking of building in your bug as most T-4 bugs as highway monsters. You do not see Porsches or Jags at the drag strips, they are highway cars as your will be. My bug is exactly what I told you to build, my case is a 914, the only difference, so the dipstick is in the correct place. My bug has blown away Mini Cooper S's at high way speeds ( not off the line ). Once the T-4 gets going it pulls forever. A Mini is smaller cc ( 1600 ) and even with the supercharger dies away. Also keep in mind the Mini weighs 2700 lbs that is 1000 lbs more then a bug. So even with 165hp vs. 125hp the power to weight ratio is on the T-4's side. After saying that if you want to stay alive keep in mind a stock bug with a T-4 is very dangerous. Mine has a dropped front end, 4 wheel discs, front and rear anti sway bars and kyb gas adjust shocks, with 195's on all 4's. Ok you can drive carefully and not do those things but, once you see the power, you won't. Also if you have the 911 fan and alt. it is going to look very mean. Any questions, I am back!! Here is some photos of my bug

I almost forget the guy with the Heat remark. He is correct, some guys that live in warmer climates do not use heaters. I use a gas heater, but in my manual is a section on cutting down the bus heater boxes. Also join the T-4 forum as one of the posters suggested they are working on the heat problem.

Thanks Joe, and all others for your input I asked today and will be able to buy the 911 cooling system, very cool, should I be looking for a 1973 or later bug or bus trans? Right now I'm still wet sanding the body, getting ready for paint, Lime Green, 1979-1980 Bug, lowered, with P205-60-14" 6" wide rims, I obviously will need to convert, at least front disc brakes as money will allow. Even funnier, I was born and raised in the Boston, Cape Cod area, cars run well at sea level, now I live at 5200 feet here in Albuquerque with a 15% overall power loss, but no spark knock problems, so I'm very interested in the type four conversion, most of my driving is at freeway speeds. I am interested in correct cam profile, exhaust, and heater considerations. I will be ordering you book to help support both our cause. Thanks again, Douglas
