INFO: Engine Swap? Transmission?

[Levo]

Hi all.

My gearbox has **** itself in my MK4 1.6L Rally.
I bought a 1.6L with a reconditioned gearbox from Sydney which I am looking to put in my Rally, but I am also gathering information on other options...

So, I have a few questions though...

1. Gear ratios - I understand that for different amounts of torque and Kw, you will need to have different gear ratios to put the power down. What I am asking, is how far can you go with a 1.6L gearbox? If I get a 1.8L or 2.0L, could I get away with a 1.6L gearbox (I have a reco gearbox)?

2. Engine - How much would I be looking at to buy a (solid) engine? I had a quote for a VR6 from a wreckers in Melbourne, which was $1, 800 without any information on how many km's.. has anyone bought an engine (including ECU and gearbox) that could give me a rough estimate?

3. Swap - To swap my gearbox (which would include checking all components and transferring the best of each car into one) will be around $800 - $1000. Has anyone swapped their engine and could give me a ball park figure?

Hi Levo,

I had a MK4 Golf, 1.6L (AKL), with a DUU gearbox. The gearbox shot a rivet through the case, and stuffed it.

After many quotes, including 2nd hand gearboxes, 'reconditioned' gearboxes, 're-built' gearboxes, etc. I ended up buying a GTI 1.8T engine, gearbox, ecu, driveshafts, subframe, etc to swap all from one driveable write off. The 1.8T parts cost me about $1600, I also bought parts for a water pump/timing belt etc replacement while the engine was out, before install to mine, $400, and then the labour would've cost me about $2000 for the swap, which may be more expensive if you only give them parts instead of 2 perfectly working cars.

All up about $3500-$4000. A lot of money, but a reconditioned gearbox + clutch + install was almost the same, and I would've been still stuck with the wussy 1.6L engine! I'm MUCH happier now.

Also, Clarkee has a properly rebuilt 1.6L gearbox for sale! I would've bought it for mine, but it didn't match & I'd already gone ahead with my expensive transformation.

In hindsight, I should've bought a 2nd hand gearbox & sold the 1.6L car, then maybe bought a gti, but I'm happy where I ended up, it just cost me a little more. If you are able to do all the mechanical/labour, you will save yourself generally half the cost on either option.

To put in a VR6, you'd need to either get a compatible FWD gearbox (the VR6 Mk4s in AU only came as AWD as a Bora V6 4Mo), or if it's a Mk3 VR6, you'd be unable to put it in the car at all (even if it'd work, it'd never pass engineering, as the engine can't be older than the chassis).

That's a bummer. I wish they'd sold MK4 VR6 Golfs in AU.. AWD would be amazing, but I'm sure REALLY hard, if actually possible?..

[Levo]

Cheers guys!

I had the same issue with a rivet through the casing. Was not good timing either!
I have a reco gearbox which came in the golf I bought for $2500 from Sydney. Not a bad buy!

If only I had the utilities and time to do it myself... The GTI transfer doesn't sound like a bad option, but I wouldn't be able to drive it (I'm still a lowly P-plater).

Ah! I didn't know that about getting a car engineered, thanks for the headsup. Very useful information.

Would there be many people interested in buying a parts car from your experience?

Apparently possible, but requires lots of work (changes to the floorpan, etc, requires a donor AWD chassis as well).

Yeah, I just went through the Rego & Insurance process with my 1.6L converted to 1.8T Golf. Apparently if the engine didn't come in that exact body shape, then it needs an engineering cert., and it is also then classified as a modified car, modified engine. And then that throws a heap of problems your way for insurance + as a P Plater... So any engine that wasn't already in a 5 door mk4 golf (in AU) = modified.

Apparently possible, but requires lots of work (changes to the floorpan, etc, requires a donor AWD chassis as well).

Thanks Manaz. Similar to R32 swap then I guess. I'd love a 5 door R32!

Mmm... Those R32s are so god damned sexy!
It's a bit of a shame that more golfs weren't AWD!

Yeah, and besides the awesome drive, my rear wheel drive mates wouldn't give me any stick either!

[Levo]

The peer pressure and the friendly competition is a lot of what compels me to modify my car...

Especially my mate with his Honda Prelude...


OH! I have a question, do you find that with your GTi conversion that you have quite a lot torque steer?
... How does it handle now that you've done the conversion?
