Superchargers for Mk2 Golf 8V Digifant

[bam87]

Hey guys, I have been searching for idea's on how to upgrade my MkII golf 1990 model and have struggled with the idea of an engine conversion because of the cost. I recently came across a supercharge kit from bahn brenner. I came up with some questions and would hugely appreciate any sort of answers.

1) Has anyone fitted a supercharger to their MkII golfs?
2) If so how does it rate against other golfs and makes?
3) Is it a viable option cash and power wise?

Here is the link ....

you are looking at over 4k once you get it over here, so it isn't that cheap.

For that sort of money you could keep the car n/a and probably get similar power.

They do look like very nice kits though as they come with everything you need. But for the price you could easilly get a 16v and run it on digi as i was looking to do. You will have similar power and they are capable of alot more power also.

Once you get it here, it'd probably be close to 5K the way the dollar is going!

150BHP is reasonably achievable with the old 8V, very easily achievable with a 16V.

You'd probably come off a bit cheaper with a 16V.

Depends how much more you can get out of the SC kit. While the kit looks very good, which should make for easier intall (etc) bang for you buck value isn't very high IMO. Unless you can get an extra 30HP with a cam and exhaust (for example)

Perhaps you should email BBM about power upgrades, ie, high boost, cam, tuning etc. they should know best, since it's thier kit afterall...

if you go with forged internals, rods rings pistons, you can run much higher boost without worrying about something melting. there's a guy on vortex who supercharged his 8v digi jetta, except he ran an aftermarket ecu, forged internals and a charge cooler. made about 200 hp though.. forced induction on dubs in australia is always very expensive..

.... made about 200 hp though.. forced induction on dubs in australia is always very expensive..

is that all? Not very much at all. Think of the money he would have spent too.

Better power out of a turbo in this case I reckon

[Golf Houso]

What about a 1.8T running Haltec? It'd cost around the same and produce the same HP more reliably.

[jayjay]

the thing with running different motors is engine loom. if you go forced induction, you only really have to worry about fueling. everything else is relatively retained. whereas going to 20v, it all becomes a lot more complex, well at least for me.

[Jarred]

What about a 1.8T running Haltec? It'd cost around the same and produce the same HP more reliably.

20V 1.8T would cost close to 10K once everything is done and produce more power, in stock form.

[Golf Houso]

20V 1.8T would cost close to 10K once everything is done and produce more power, in stock form.

Oh c'mon, 2k for the motor, 1k for install and 2k for the ECU, thats 5k. We're talking just about a swap here, not including everything that should be done at the same time like clutch, diff etc.

To do it properly it would take 10k yes I agree with you on that.

[bam87]

what about an upgrade such as :
Mk2 Golf/Jetta 8.5 or 10.0 Compression 2.0L upgrade 8V stroker Short Block

would i be able to make the conversion easily, what sort of problems may occur ?

Whats the point of doing it if the clutch etc is not upto it and will just break straight away??

Theres a lot of stuff you havent considered Houso. Intercooler, piping, a hundread litlle clips and brackets, ancillaries that are not included in your bargain engine, getting the haltec tuned, if you can find someone to set it up competently on that motor in this country.

And a lot more than 1ks worth of labour.

10k is more realistic.

[Jarred]

I'm not sure exactly what you mean, are you talking about using a 2L block and 1.8L head to up the compression ratio?

Engine swaps in golfs are relatively straight forward with a bit of mechanical knowledge, and plenty of time. (research)

This is all my opinion of course.
If you want 150(odd)HP:
a 16V will achieve ~165HP with intake, cams and exhaust. I'm not to savvy on digi/ECU though, but an aftermarket mircotech LXT8, would be something to look at. (or any other stand alone - only if nessecary). Without ECU, around 3K would be very achievable, providing you can do most/some of the work)

an 8V can achieve achieve that 150HP. a member on here had a 1.8L on kJet, with 135odd HP, with minor mods, but it still involved a full rebuild.
To get 150 HP, you'd need big compression and lots of head work and lots of other work. this would be easily more than the cost of a 16V + mods, excluding ECU.
The other option with an 8V is to supercharge or turbocharge, but again the cost would be much more than the 16V option (factory ECU) and unless you were to fully modify and build the 8V, in stock form only 200HP is reasonable, This option would cost about 4-5K. (not including instalation and custom work, and on a standard engine)

Hope that helps.

Exactly.

That -BOLT ON- supercharger kit seems like a good deal. Good realiable horsepower, good drivability, probably comes with WARRANTY.

Why do you guys think that engine swapping is so cheap and easy? It's not and a 1.8t on haltech will NEVER be as nice to drive as a proven well refined positive displacement supercharged 8v still running what is basically a factory fuel system.

And really, have any of you people driven a 200hp daily driver Mk1 or 2? 200hp is freaking **** loads. Hell, 150 is more than enough. Stop discrediting performance enhancement setups simply because they don't quote stupid power outputs. 10 squillion horsepower isn't everything, especially in a light, FWD ROAD CAR.

Just ordered brand new clutch set up from america should be arriving soon.
I asked around before posting this and was told that the swap to 16V so i can strap on a turbo would be more costly then the supercharger kit, Jmac also pointed out that if superchargers were not a viable option why would they have put them on the 1.3 polo and a G60 carado?

Blake

I dont think he was referring to your car.

Did you have a power figure in mind, or did you just see the kit and think, "that looks good.." if you dont mind me asking?
