Hey, my mrk2 is getting abf conversion next week, and i just wondered how could i gain power? With re-map and throttle bodies ill be running about 185bhp (thats 35bhp gain) but i want a lil bit more... what turbocharger would fit? Any power helps?

I would've expected more from the bodies set up.
A good abf on kjet with a kr head and cams will make an easy 190 without any mods what so ever.
The mk3 16v ecu map is pants to be honest.
If you are going to keep the standard ecu then I suggest getting some slightly larger injectors and some kr cams.
The standard abf cams are very mild and are this way to meet stricter emmision laws of the time.
on throttle bodies i would expect to see at least the magic 200 brake. These engines have a very long stroke and and such a naturally long flat torque curve, so dont spoil this with really wild and lumpy cams.
If you are looking for injectors I suggest looking at some from a pug 306 gti6 they are good for 240ish brake without the duration going to high, and an uprated fuel pressure regulator will help too and a fairly cheap/easy mod to boot.

I hth.

the standard ecu will work fine but if you want throttle bodies then you could run a standard ecu but you have a lot more flexibility with a stand alaone (emerald etc..)

With a stand alone ecu you wont have to run a plenum chamber or a afm and can run just bell mouths in a large itg filter so you get a huge air flow gain.

An afm will restrict the power.

to cut to the chase, fit an abf use either kjet cis injection or the standard ecu from an abf, get it all working then throw in some kr cams and a remap and you will get 190+ brake.

I promise you it will keep you happy for a long time, anything over about 250 will be hard work to launch and difficult to keep in a straight line.

what spec car are you starting with???

if your starting with a kjet car the conversion is easy all you need is the head and block. however as learnt by myself, when you tune/set the car up, the standard ignition system will hold you back, ive been told to look into mega jolt which will give more adjustability.

on kjet you also have the WUR mod which in essance ups the fuelling and gives more power, i think you can expect 20bhp. however i have not done this myself, as yet, im waiting for someone localish to say they can do it

I cant remember when it was (but recent) and it gave a link on how to do it and set the pressures correctly.

search it out, it was interesting.
I have previously done this mod (about fifteen years ago) and it does improve things but it doesnt give 20 brake , id say more like five.

Sorry to hijack the thread,,,,

ah yeah i did see that thread.

ive never done it myself but when you hear about it its supposed to be the nits t*ts of a mod.

either way if it makes more power and its safe then surely its a win

I agree, especially as it uses genuine VAG parts then its defo a win.

Guy

I have found out that the abf cams are a tad better than the kr items so its not worth the swap. The 9a cams are milder.

I have also found that you can use 2 exhaust cams, 1 chopped. Mixed reviews on its performance though


simon on here(mk1g60) runs zx9r carbs on his abf and its rapid as fook

The zx9 carbs are always going to be a good way to go just because of the cross sectional area of inlet.(i bet it sounds glorious too)
As for the kr/abf argument .... VW originally tuned the abf to 175 ish brake and then had to detune it for emmissions and so as not to cause an issue with the vr engined models, they did this by having a different cam profile (its not all about duration or lift) and milder map on the ecu.
Stand the kr and abf cams side by side and there is a marked difference, I've done it, the 9a/6a cams are all pap I agree.

I've tried speaking to my buddy Aidy about his fuel pressure gauge and he's not answering his phone at the mo (the moody sod) so I may not be able to sort your car at the weekend Lee.
