what is needed to fit a wbx into a bug?

cool, yeah i have a 200mm type four flywheel, just wondered if the clutch off my bug would fit or i'd need to get another new one.

the engine is in working order, would you recomend not splitting it unless there is a prob??

Not sure if the clutch is compatible. I guess provided the bolt pattern is the same it should work.
As far as the engine goes do you have much service history on it?
Taking the engine out for repairs is a PITA with all the water pipes etc so for the sake of an £80 gasket kit whipping the heads off to confirm the state of the heads whilst the engines already out is probably sensible.
If a stud breaks then it would likely snap anyway during use and surely the long term goal is something reliable as well as fast.
Getting the wrist pins out is a pain but still perfectly doable without the need for any specialised tools.
Up to you mate but if the history is good then I would leave it is as.
As a matter of interest where did you source a 200m flywheel with the 5 bolt crank pattern?

the engine is in quite good nik, has bout 100k on it so not too metal. i might run it on the test stand first and see how it goes.

the flywheel is off VZi. type four i think.

Sounds good.
I'll see how well my stock 215 clutch holds out when I get the carbs properly jetted otherwise I may well be sourcing a 200mm and an uprated clutch setup.
I look forward to seeing project pictures

For 200mm flywheels jake raby in the U.S. sells those for his type4 engines, these can also be used for the type5. About running coolant hoses the vanagon stainless steel lines can be shorten. My friend here in Jamaica ran a 2.1ltr waterboxer in his 66 beetle untill it caught a fire. It was great driving in that car loads of torque.

The stock 200 mm bug pressure plate and disc fit the type 4 200 mm flywheel (at least the original '69 flywheel from a 411, i don't know aftermarket).
It will hold well enough (i put these on a type 3, which is heavier than a bug).
The 215 mm stock bus pressure plate holds very very well in a bug, i can compare with the fastback. The 200 mm won't slip below 90 hp or so...
Should've mounted the 215 on the fastback, but the 411 flywheel was all i could get at the moment...
AMBROSIA, where did you get those dellorto manifolds from? They seem to be specially designed for the wasserboxer, not type 3.

cool, that's good news. am building a test bench at the mo to test run the engine out of the car. should have news soon.

thanks aagin for everyone's info.

here's something...

i have not had a look at the engine since i dropped it off at the stores. does it have a fuel pump on it or is it on the tank?

fuel pump is electric and is fitted under the floor, outside the fuel tank on a t25. did you not get everything for the fuel injection? if you are running the injection then you've got a lot of fuel pipes, feed and return to sort out too. prob much better to go same way as ambrose, easyier to fit and prob more power to boot, with twin down drafts

hmmm will have to have a look then, i want to avoid carbs as can't be asked with jetting etc. at least for now.

what pressure is needed for the EFi? can i use an aftermarket one? and would it still need a return?

thanks

1303wasserbug · Post by **1303wasserbug** » Wed Jun 11, 2008 1:01 pm

yeh needs a return. no other option if you want the fuel reg to work. some people just return the fuel via a tee in fuel hose, tank side of the high pressure pump. not the way i'd wanna do it though. fuel pump is just a bosch in line pump. thou there are a few with different specs. best look on the fuel injection forum. your also gonna need to modify the rear inner wings to accomodate the fuel rails too. there is a lot more work then you think, even keeping the stock vw set up. wiring and ignition is real easy thou, just as long as you have all the engine bay wiring and it has not been bucturched

Stephanhipwell · Post by **Stephanhipwell** » Wed Jun 11, 2008 1:30 pm

cool, yeah the engine bay will be chopped up so no wos. i will have a look on the fuel injection bit.

Stephanhipwell · Post by **Stephanhipwell** » Wed Jun 11, 2008 1:41 pm

i have had a look and would something like this do?

Flow rate 130-180(L/H)

Pressure 3.0(Bar)

if the pressure is the same as what i need on the efi would it still need a reg or is there a bypass on the fuel system?

1303wasserbug · Post by **1303wasserbug** » Thu Jun 12, 2008 11:58 am

you'll still need a regulator and a return line. the regulator takes a reading from manifold pressure and varies fuel presure for different driving conditions. read though the fuel injection forum and you will find all the answers you'll need there for fuel injecting a bug
