Hi
I am running a 71 1300 & would like to know is it possible to up grade to a 1600 with out much of a big change I know a change of engine is out of the question but can you change the P&B & not much else, has anyone tried this or is it not possible.

Barrels and Pistons do it, up to 1641, might need to upgrade the carb to suit (Solex PICT 34) Many threads on the forum regarding this modification.

You will 1600/1641 B+P's, 1600 cylinder heads or get yours machined to fit the larger cylinders at the top. The 1600 has the larger 34pict carb but this does not bolt to the 1300 inlet manifold so you will need a 1600 one. The aluminium end manifolds are larger on the 1600 as well but you can grind a bit off the insides of yours so they fit on the manifold ends. However if your bottom end is not in good condition, it will not last long with the extra power

........... I know a change of engine is out of the question ........................

I presume you are stating this from a cost point of view? 
Might it actually be as cost effective to change the engine than get lots of new bits to bolt onto an old on.  You'd have your old engine to sell to offset some of the cost.  You could get a second hand 1600.
Just don't rule it out without checking the sums is what I'm really getting at.

Don't do it unless your bottom end is 100%. ie factory spec endfloat and good oil pressure or it won't last long.

Dave...I`m having to stick with my original type 1 1600cc motor for the moment... With regard to any future change what is needed to fit a Type 4 motor to the standard gearbox I have? (swing axle version). Is the type 4 motor 2000cc and is it much heavier than type 1?  Nothing definite planned yet just thinking ahead.

Thanks for the advice some good points of view, I did have the end float repaired and head skimmed so good block, think I will look out for a 1600 and sell mine on, so will keep an eye out for one.

This might help regarding the weights/sizes

Hi Paul, the type 4 engines come in 1.7, 1.8 and 2.0L sizes. they are about 40 kg heavier. I have put a few in buggies, the main problem with them though is that you can not get buggy dress up bits for them so it is a van exhaust or custom made job. To fit them, you need a 200,210 or 215mm flywheel off the 1.7 or 1.8L engines. The 2.0L engine has a 228mm flywheel which fouls the gearbox with the clutch on it. You need to take the gearbox idler shaft bearing support out of the end of the crankshaft. You then have to take your flywheel to a machine shop and get the centre machine out to take a new idle shaft support bearing. this is because the type 4 gearbox's idle shaft is 1/2 an inch or so longer than the beetle box so moving it into the flywheel solves this problem. The fuel pump on the type 4 engine fouls on the gearbox cradle, so blank that off and put an electric pump on. I would recommend new gearbox mountings, I have put a Rhino nose cone mount on mine  The extra weight of the engine, drops the rear end down by about 1ins

Have a read of my build thread in the Members Buggies section, as I fitted a 2 liter Type25 to mine and covered the conversion in a fair amount of detail

The sticking point is the exhaust - you will need to make one as zero chance of anything off the shelf.

I built a 2054 type 1 engine, 134bhp and 151ftlb torque....goes pretty well 

Its on my build thread

Thanks Rob.. That`s it then. Need to definitely stick with my type 1 motor for the moment. The extra weight & rear end drop is the decider for the moment. I will explain this fully as I go through the build stages. It`s that IVA thing.

Thanks Dave .... will take a look
