Labour?
Parts?
Not exactly the kind of thing you do to kill some time on an afternoon is it?

Perhaps if you source the engine and loom etc etc yourself JBS would be a bit cheaper - assuming that the £4500 i
includes sourcing a powerplant!
Why not give them a call to discuss?

Engine is extra.
Its quite a big job, lets not forget all the other extras your missing, custom drive shafts for a start!

I would of thought it would be a big headache doing this yourself, the company would know all of the problems to get around and would know the best way of doing everything.

Quite hard in the Polo. I enquired myself when I had my mk5, basically the chassis in stock form isn't strong enough to fully support a 1.8t. This does not make it impossible but I believe it does need strengthening in order to carry the power. In addition is is quite a squeeze to get a 1.8t in there and it is a lot of work for the loom etc.
If you've got a GTI, I would suggest either supercharging/turbocharging it if it's more power you're after with a less labourious task...if you can call it that.

Well, i think i may just get another car soon anyway, as turbo charging the standard lump is i feel 'like polishing a turd'.
Starting out with a decent tuneable engine is always the best. Arr well, 1.6 just doesnt cut it for me anymore. . . .still fun though . . .

You need custom drive shafts too and the loom rewire really won't be "quick"
There is a lot of work that goes into making it all fit, and stay fitted, in the engine bay.
Someone did do a home one over a weekend for a 9n though, but he is a VAG mechanic

that be me then
mine took a bit longer than a weekend to do the full job , but now i know whats needed i could probs do it in weekend if all the parts are to hand
he is a VAG mechanic
that bit aint me

i have looked into doing a mk4/5 and its the fitting into place that will rack up the labour costs
shafts and wiring aint that expensive

The 9n engine bay will take a 1.8T a LOT more easilly than a 6n/6n2...
Just sayin'...
JBS start their 1.8T conversions at about £7500 "drive in - drive out" (ie that includes everything).
Have a look round Inters next year at all the 1.8T conversions and then go to the JBS stand and have a look at theirs. There IS a difference. The majority of the other conversions you'll see use non-drive-by-wire and non-VVT engines with aftermarket ECU's. JBS use the proper ECU with DBW VVT lumps.
I don't want to sound like an advert for JBS, but they really are at the top of the game.
Not saying you couldn't do it yourself, but in a 6n/6n2. expect it to take a LONG time.

Will deffo agree, there conversions look bloody good
go have a look at jamies r4byy 20v in a mk4, then go look at Ash's L9 ACP
the difference is obvious
the later is a JBS car, engine looks like stock fitment
same with badger bills missus's lupo, looks stock
and as for not being that hard, well, yes, yes it can!
