Aircooled VW South Africa

Howsit guys i'm planning on building a turbo type1...
I buy the parts as soon as i get cash piece by piece...
I want to get all the main components for the turbo conversion first.. and then maby think about buying some stuff to increase the cc'S a bit maby just under 2000... but that will have to wait.

Any help or advice will be great..

Parts:
Throttle body with injectors (single point injection) - Yes
Electronic fuel pump with surge tank – Yes
Gotech feul management – Yes
Electronic dissy – Yes
Golf 1 square coil – Yes
Turbo with internal wastegate – need
Dumpvalve - Need
4 into 1 exhaust that will be changed to become the turbo manifold – Yes, but who can help with the welding and pipe bending?
J – Pipes (thinking of keeping the original ones (for the heater) , can this be done or do I need new ones)
Turbo cam - need
Oil cooler kit 72 plate with sandwich adaptor – almost got it
Oil pump ( ?? what to get here) - need
Booost pipes – need to be made up… who can help?
All other small parts I will get, like fuel hoses , tubing ect.

Then maby bigger pistons, maby a fancy 84mm crank?( but thatl have to wait)

Any comments and/or recommendations will be great thanks guys

You need to be sure on the CC `s when buying the turbo as there are a few things to consider when selecting the size of the turbo according to cc
On your list you got throttle which one you got early uno or Golf early Bosch

You can retain your std J pipes for heaters just weld a flange on to couple the pipes together
For the branch it is not to difficould you can buy bends out of the scrap bends bin from TNT.
Then from there build your own branch and boost pipes,or you use welding wire and shape it to the shape you need and get them to bend it to that shapes

You really need to decide on the engine size before buying the turbo.

Going from 1600 to 2400 is a big jump in itself. If you have a well setup turbo running 1bar boost on a 1600, then convert it to 2400, you will be down to 0.6 bar. This will affect all sorts of things, temps especially. Plus the turbo will be way too small for the 2400. Make up your mind exactly what you want, then buy it and put it together without changing anything.

i suspect a turbo with heater boxes might not be a good idea, heck those things overheat standard engines occasionally.

Good lucky buddy. Seems like there are quite a few guys who are building nice ACVW engines these days. I'm keen to see how it turns out!

Is bolting on an ac porsche engine not a more viable, reliable option?

Money and size....
aircooled 6 cyl doesnt fit inside the beetle engine bay
Newish aircooled 6 cyl engines can sell for up to R120k

You want a Porsche, be prepared to pay Porsche prices.

Thank you Herr Hitler. If it wasn't for your Nazi thinkin, l wouldn't be driving an aircooled Peoples Car! R120k for a motor

@ Bugger :I have the Golf early Bosch. Will this be sufficient?
ok maby i should just get a t3/t4 hybrid as this will be sufficient for 2000cc plus motor as well as a 1600cc-2000cc?
Then i need an external wastegate?

For a nice engine and to sort out principles I would keep it 1600
add a counterweighted crank
Still use the stock cam if money allows buy a turbo grind from a reputable cam manufacturer.
Go for the FI
std oil pump is good enough but add a filter and big oil cooler
I would not use the heater boxes
I would also use a dog house fan shroud with a type four cooler as well
the turbo should be a t2 from a uno or similar
No need for o ringing or other fancy ideas
With this setup cost could be very affordable and the power will surprise you
Lastly I would eight dowel the crank and flywheel

Yes that wil be sufficient for mild power
You can get a brand new Turbo for 1600 from Volkspares at around R3800 with internal wast gate

Why do you guys say no to the Heaterboxes why can you not enjoy your bug in the winter
a 1600 like this that you plan to build wil easily make 80Kw on the wheels and be reliable with heater boxes
That is my personal opinion and experience on the heater boxes with all the right tinware I see no problem
Tony /IMPI why you guys say otherwise ?

surely with the heater boxes being in place they will get damn hot adding heat to the head, plus their limited size (they are smaller inside than a J-pipe) will cause a pressure restriction adding more heat to the head.
Keeping air blowing over them might help, but then you are reducing the power available as you are cooling the exhaust.

No, I dont have turbo design experience but I have seen the inside of the heater boxes.

I agree with Tony I dont like them for the restriction before the Turbo But nothing is stopping you from cutting the heaterbox open and substituting the internals for a J pipe. I stand to be corrected but some Fleetlines may have come like this as I have seen heaterboxes looking like this on a few.
T2 two turbos can be had new or secondhand for very little money if you search dilligently
Armand

my limited turbo knowledge also sides with the no heater pipes. less heat, and better breathing makes for a happy turbo.

what would a complete engine that you suggested cost with fitment IMPI??

Ok just spoke to a friend of mine that I did my 1st one with and nowadays the price tag is around R24K on to your exicting motor with out opening it
They have built one with heaterboxes as the client also wanted to retain heaters and a few with out and the one with had no problems.but alot more work to get everything to fit
With the 4in2one it is easier

Std a beetle makes around 18-24KW on the wheels 1600
With turbo "de" tuned it makes 60Kw on the wheels 3xtimes that of std and Reliable
The boost can be turned but then dettonation comes to play with more power with out a intercooler or charge cooler

add a counterweighted crank

How is this done, who can do it... COST?

Still use the stock cam if money allows buy a turbo grind from a reputable cam manufacturer.

I will be buying this from volkspares

I would also use a dog house fan shroud with a type four cooler as well

Could you tell me more about this please, as I have very limited experience on this, why is it needed and what sort of gains will it produce. Cost?

Lastly I would eight dowel the crank and flywheel

I have no idea what this does? And why? Cost?

Std a beetle makes around 18-24KW on the wheels 1600

I had no idea its so little

With turbo "de" tuned it makes 60Kw on the wheels 3xtimes that of std and Reliable

Is this on .8 bar?



lastly, is it worth it having the heads ported, can a big increase be expected? Can this be a DIY job, or is that not reccomended? what would the cost of this be if I have someone else do it?
