Hi Guys I have started this thread to give as much advice as Possible for the guys that contemplate in fitting a Rotary in to a bug / Ghia /Type 3 / Bus etc. to try and give them as much as possible heads up info of what it takes and cost
I have a bug by me that has the conversion already done which I have stripped and redoing some of the things for the Client and fitting a Seriously strong Bugger Transmission to the bug
This is a pic of the bug
946- (Medium).JPG
A look at the buisness end of things
I had the Bug on one of Speed and Sound`s Dyno days and it made 100KW on the wheels
Now that is what a std Rotary turbo makes on the wheels with .4Bar boost
Have already sent the turbo in for a small upgrade and the aim is that the bug willbe making 145Kw on the wheels which still make the car really reliable to drive and with a high low boost set up really fun aswell

The doggy box was removed and refitted with multi plywood which I immediately have removed for propper slanted plate fitment and the wiring all worked but some wires was joined 5 times in less than 200mm once all the insulation tape was removed

I am also in the prosses to start with Phantompondler`s Puma rotary turbo Project and will as I go along post pics and info.One tricky thing with the Puma is going to be fitting the Radiator up front and conseal it so it does not shout out to you I AM W/C but just leave the others in his dust

I Edit as I have posted the 2nd pic twice
After the motor and transmission was removed there was a serious spider web of wiring that was in the bug
The guy that has built the bug must have a Electrical trade as all the Positive wires were taken to a central point and joined with Chalk blocks.And all the Earth wires aswell one earth wire ran from the EFI fuel pump right next to the battery to the Chalk block and all the way back again
Please Dont think I am shooting the guy down that did the bug he did a nice job with alot of the other things on the bug it was just Snaaks to find something like that in a Vehicle

After me and my 2 trusty friends the Side cutter and the putty knife(So Dirk I have one to open your wrapped tranny when he arrives )got stuck in to the wiring of the Bug and the Microtech EFI.
I have cut out quite alot of wires that I deemed unnessasary

and will be visiting the Scrap metal dealer

Here is a closer look of the inner of the engin bay before I have stripped out everything
The long cylinder that is connected to the fuel pump is the surge tank which will probably also be replaced as it is made out of stainless steel and is F@rken heavy and the fuel supply and return lines come from the bottom right of the bug and the inn let and 2 returns are on the Left of the tank so there are far to many fuel lines under there to My liking
As the coils on the right hand side I will make a bracket on the right of the motor to bolt them on to and ceep the side wall as clean as possible

I hope it's sharp, you have to go through at least two layers of bubble wrap and 4 layers of bin liner

Not to Worry Dirk have spare blades
I have cut the plate and weld it in and two small pieces for the sides
The plate does not get welded all round as I seal the plate right around with Fiber Resin and matt and then Every thing gets stone chipped in the motor bay with Clear coate over it all
Hope you are proud of me Barry as I have spend a littels more time in making a template for the sides

This bug had an amaizing amount of unnessasary holes drilled from the engin bay to the wheel well both sides Left and right
1531- (Small).JPG
I have closed them all up when I glass fiberd the slanted plate in to get every thing looking better when stone chipped
1530- (Small).JPG
Here is a pic after the resin and fiber mat is put down you do not need alot around 500Ml of resin to do this whole job
You will see I have also removed the back window to have better access and work space When the appy(WIVE) is close by to hand you a tool or two

Stone chip has been done inside and out side
Ance it is coverd with a coate of 2K clear it will brighten up the engin bay and it is very easy
to clean the engin bay aswell with the clear over the stone chip as it takes away all the rough edges
Appologies for the dust mites

in the pics it was still quite alot of stone chip overspray in the air

Thanks Chris
When ever I do something whether it is vehicle related or Transport related I try and see the end result and also If I was the Client and I go and fetch my bug by Bugger. how would I feel over sertain things and how would I have wanted to recieve it back
So I try and always put myself in ME the Clients eyes and I am not easily pleased as it comes to sertain things
