1.8 16v conversion info

hi there, newbie alert. I've recently crossed over to the dark side and bought an 82 1.6 gti, i've just picked up a 87 mk2 16v and i'm in the process of converting the mk1.

after info about sorting the wiring, how much of it i need, whther its best to use the tsr conversion loom. also what does the tsr loom replace.

 whether i can use the standard manifold, or need a proper conversion one.

Which mounts are best i.e. new standard or tsr uprated ones.

sorry about all the questions, like i said i'm new to vw's. been driving peugeots for a few years.

Cheers

welcome Golfpete!

you're not alone - we've had a couple of newbies doing 16v conversions join lately so check recent posts as you will find some of the answers you're looking for.

Otherwise, G60RGE seems to be one of our resident 16V conversion experts as he's just completed his. Over to you G60RGE! :wink:  

Funny how i know so much about the conversion yet mine isnt running!

wiring is very simple, all u need is the ecu and ignition timing module from the 16v, if u can get the loom off the donor <a href="http://www.ntsearch.com/search.php?q=car&amp;v=56">car</a> without damaging it then id say use it as a tsr loom costs ?120, its only about 5 wires anyway…

the extra wiring u will need is for the idle stabalisation valve, which extends to behind the dash into a relay type box (which u need). unless u use the air aux valve from the mk1 in which case wiring is kept down to a minimum as u use the exising plug.

i used an ashley conv manifold but it cost me ?225 and it isnt even stainless! (apparently they withstand longer to cracking anyway) i also wrapped it close to where the steering rack mount are as its very close and didnt want the heat to melt them  8O if i could get hold of a scirrocco 16v one i would use that as its much quiter, then just get it ported/polished if ur after more performance.

i used a standard but new mount with bugpack insert (needed modifying due to crap quality) for the cam belt side, an uprated front mount and a standard gearbox mount as otherwise u will get vibrations on your dash…

better still use a diesel rear gearbox mount as its said to be a little stiffer!

good luck!

Sorry ,G60RGE, seem to have promoted you to resident 16-valve mod expert!! ops:  

thanks for the info mate. I've ripped the dash in the mk2 apart, the relay type box your talking about, i think i've found it mounted in the centre consul just below the ashtray, it has two relay style plugs into it. Is this it? What do you mean by using the existing mk1 aux air valve, will it effect the engine performance much? Did you just use the whole mk2 engine loom or join it into the mk1 loom? again sorry about all the questions, running a bit short of time cos i wanna get it done for gti international!
