Hi,

Im going to get a 1.8T dropped in my 6n2 and was wondering what you thought as to the max power before needing an LSD?

I am aiming for about 240bhp, would you go for a k03s or a k04 turbo?

Do you think 280mm brakes will be ok running that much power?

and finally regarding traction control, im presuming it is managed by the ECU so if the donor car has traction control then once the engine/ecu is transplanted my GTI should have TC too? And if so can it turned on/off?

Thanks for any help

Edit.
I also wanted to ask, Im getting this done basically as Im so sick of my continual gearbox problems but otherwise love the car. I just want to not have to worry about the GB and its repair bills. If the conversion is done properly am I likely to have a rock solid car or am I opening up a can or worms by having to maintain a heavily modded car?

Interesting question about traction control...

I am not sure if the golf ECU will talk to the polo wheel sensors and braking system...

You could get it to work, but in all likleyhood...it wont!


There is no max power for needing an LSD...Its all down to driving style...

If you want it as an every day car then no LSD required..

If you want to be able to hammer it around corners etc then yes...get an LSD...

again, the 280mm brakes would be ok for an every day car, but if you want to hammer it I might be tempted to get some 4 pot brembo callipers just to be sure...

It all comes down to budget....the 280mm brakes WILL WORK, but if you can afford better and want to hammer it then seriously consider it....


Are you replacing the standard suspension mounts with something a lot stiffer?


GOod luck with it

Thanks Tegwin,
Regarding the suspension mounts im not sure if they are getting replaced or not, the only discussion i've had regarding suspension was that my eibach springs and OEM dampers are to be replaced by FK coilovers.

you've got to think about how much power a car like a polo can realistically use. I'm going down a similar route to you for much the same reasons, but im planning to keep the standard 150bhp 1.8t for time being to see what its like do drive, then if need be i can map it up depending on what i feel it can handle. I might prove myself wrong but personally i think 240bhp is going to be very difficult to put down onto the road. IMO if you cant nail it through the first few gears without spinning up then its just wasted power.

Agree with what he said..

Because of the nature of the polos suspension (elastic mounted bottom link)... If you hammer it too much its just going to all nasty... (its mushy enough with standard gti power)


The new 150Hp turbo GTI is scary fast.....and its a lot heavier than the 6N2...

So perhaps just stick with the standard engine and see how things go.... I thik 150Hp and a turbo torque surge as standard will be enough to make you happy


I think if I were wanting to put that kind of power into a polo I would be using polybushes.....or redesigning the entire front suspension system to make it totaly rigid.....Using solid bushings..! BUt its a polo FFS...lol

yes i would go with polybushes as their very good! especially with using high power in a diff car. go for it mate its what im going to do but i think im lookin at 300BHP well thats what im hoping for...

How much is 300hp guna cost?...

Plus insurance..

A powerful 6N2 would be awsome, but I cant help thinking that the time and money could be better invested in something thats already quick lol....

1.8T = lots of power in an instant, relatively cheap (considering gains per pound when tuning the standard 1.6)
Tuned 1.6 = expensive (gearbox will have to be upgraded), limited power if not using a turbo/supercharger, more unique though and sounds amazing

Whether using either method, I think anything over 220 bhp would be a little silly. The GTI is pretty good as standard, making it faster would make it better, but make it stupidly quick would make it fun in a straight line but ruin it otherwise

that is a very fair comment tegwin..i could go and spend it on a higher performance car. but i just got this little image in my head of somthing like and evo or similer pulling up with a grin on his face cus my arse is more or less sitting on the floor. then he goes for it and instead of pulling away the lil polo just soars past. just a lil dream i had lol..... its just when people dont exspect it out of a small car. when you see a evo you think ooo thats gotta be fast its an evo!
300BHP can be done one of my mates works for vw and he put 1.8t in his mark 2 golf and he pushed out 400BHP until it sucked a valve thro and then thro into the turbo only to be spat out the exhaust. nice!
im planning on gettin my engine out of a Audi TT BAM code engine 225BHP then remap that to 260ish then few other little bits to tip me over 300BHP. all my chassis is going to be welded up and strengthened and polybushed. custom mounts and drivesshafts. im really looking forward to it! im doing this all myself as i work at a main dealer (Subaru) and have the space to get it on a ramp. im just planning to get all my bits together that i need then fit it in one big lump. if you want a place for convertions i dont no where you live but JBS auto design chesterfield do 1.8t convertions in more or less anything....think they have a website! hope that helps

young dubber I know where u are comming from..

I had a similar notion but was going to go a bit more in depth than you...

My plan was to get a Mk2 golf shell and stick a 1.8T engine in the middle using the passat transaxle......

Rebuild the shell with double wishbone suspension front and rear....so it would be an all out sports car with a VW body....

but sadly I drew up the plans and accidentally forgot the VW part, so it now looks more like a supercar...


However i still really want a mid engined golf.....sooo tempting for my next project!...

Yeah i could just buy something thats already fast but that I mean i'd have to sell the Polo and I just cant bring myself to do it, apart from the gearbox its a crackin little car that i've grown really attached to.

Also the look on newer, more expensive and supposedly faster car drivers faces as you pull away is a big draw, id be lying if i said otherwise . And I'd love my 6n2 polo to be faster than my mums stock 9n GTI, and be able to put up more of a fight against my dads BMW 630.

Ok so maybe im going a bit ott aiming for 240bhp, but if im going to spend 7k i want more than just an extra 25bhp! Maybe something in the range of 200-215bhp from a 1.8T 180PS would be a little more realistic and less hardcore than my S3 plans.

It is my daily driver afterall and like someone said I dont just want to have straightline fun.

Anyone got an idea on how much Polybushes are likely to set me back? And are they difficult/time consuming to fit?

I totally agree. A 20vt conversion is money down the drain. I just don't understand the financial sense behind it.

Even if you sold the car for £2k, it wouldn't take much more to buy a mk2 ibiza cupra.

The polo isn't the greatest chassis to begin with, there are cars that handle much better and are more fun to drive well within your budget.

to elaborate on that...

6n2 polo gti

1084 kg 125bhp 115.35 bhp/tonne

9n3 polo gti

1164kg 148bhp 127.15 bhp/tonne

not really that much difference....BUT

remapped 9n3 polo gti

1164kg 200bhp 171.82 bhp/tonne

that's more like it

Set of Polybushes will set you back about £90...I think..

Be a bit of a fiddle to do, but deffinately possible... I think the general suggestion is that you set fire to the old ones and then use a cold chissel to remove the shell once the rubber has been removed...


I do really like the 6n2 polo shape....but as has been said, its a bit floppy.....mhmm....

An old style 1.8T audi TT can be had for around 7K .....OK so it wont be mint, but those things are rather fast! Really like the old style with the sport interior!

Tegwin regarding the 'flopiness' of the 6n2 would a set of strut braces not help sort this out?

mk4 glx 1.6 I know I could buy something fun within my budget but whatever I buy im gonna want to modify, new wheels, lowering, air-filter, and probably exhaust for starters and that is all more money....

Financial sense.... thats deffo not my strong point

ahhh im seconding guessing myself now, and begining t0 have a few (small) doubts about getting this done. All I could see previously were the plus points.
