Remap my MK3 GTi, HELP?!?
« on: 27 February 2017, 21:58 »
Hi everyone,
So last night, I finally got my hands on my first MK3 GTi 8v, R reg (1997)- I believe, I am from Ireland and moved to the UK recently so I due struggle with the plates here, haha.

So basically I want some info on remapping these cars.... yay or nay? Pros & Cons?
Will it effect insurance hugely?
How will the car benefit from it?
What kind of gains will I see from it?
What should I add in to aid the map.

Any and all help is hugely appreciate.  :smiley: :smiley:

From my experience of naturally aspirated a map (im sure mk3s are a chip) isnt going to do alot.
Someone might be along to say different though. For the money id rather spend it somewhere else on the car

Depends how much you like work. How much you want to change.
Youll need to splice the mk4 loom into the mk3
You could use the standard gearbox and flywheel but how long it lasts i couldnt say.
The next option is a 16v mk3 gearbox and flywheel plus hydrolic clutch set up
Interooler and pupeork
Down pipe and exhaust
Roughly. Theres probally some bits i missed but its been a couple of years since ive done a 20vt conversion

16V May be the simpiler project so you recon?
Can your turbo the 16v and still keep the 8v gearbox, clutch, flywheel etc.?

Also, I cant seem to find any forums or threads for a 'how to do' conversion.
any links??

Theres some on here definately. Alot have people have done it.
You could turbo a 16v but the box is still the weak point.
Its also easier to find a 20vt than a abf.

If you change the engine then I wouldn't keep the 8v box because they're very weak.

What's your budget?
