Cooz93 66 Posted May 26, 2015 Report Share Posted May 26, 2015 Looking to convert my obd1 dizzy vr6 to obd2 coilpack. Looking for some advice form someone that done this conversion before as after reading many threads, I'm still unsure what's needed.PartsCoil packObd2 ecuEcu harnessEngine harnessObd2 MAF housingObd2 throttle bodyObd2 intake manifold Upper timing chain coverIs there anything else I've missed? How difficult a task is this going to be?The reason I'm doing this is for when I turbo or supercharge it. From what I've read and been recommended by C2 and UM obd2 is the best way to go..I've found a guide online that speaks about converting a corrado to obd2, how similar will this be to the golf?Any info appreciated:) Link to post Share on other sites
Reaperx 181 Posted May 26, 2015 Report Share Posted May 26, 2015 I haven't got round fitting mine but doing the obd swap myself. Mine might be easier as my obd1 is coilpack. Pretty much plug and play from what I have read and your parts list seems about right. You will have to get the new ecu imobiliser deleted, united motorsports will take care of that. If your going fi might aswell get the ecu socketed whilst its there so it can take a tuning chip. Link to post Share on other sites

I think the only thing different is the top chain covers, might be wrong though if you are doing them too! Also possibly a cam sensor which I missed out. Any idea how much that work costs? Also can it be done off the car as I'm up on Aberdeen so quite far away! cheers Link to post Share on other sites
Reaperx 181 Posted May 26, 2015 Report Share Posted May 26, 2015 I wouldn't know how much someone would charge to do the conversion as I will be doing mine myself once I have the rest of my turbo conversion. Just waiting on the funds for the last few bits and trying to make space at home to work on it. There are a few people on here that have either done the conversion or had it done for them.

Also decided what management your going to run with your turbo set up? Link to post Share on other sites

Also decided what management your going to run with your turbo set up? yeah I will be using united motorsports they have an off the shelf setup for my build. I'm aiming for around 300hp anything more will be a bonus. If you email united motorsports they will give you advice on your setup and recommend which software to use. Also just send them your ecu and they will do the work for you with the socket imobiliser. I haven't had chance to see exactly what is involved with the harness. But when I finally get round to doing it (probably over winter) the full front end is coming off to make life a bit easier. Link to post Share on other sites
Cooz93 66 Posted June 6, 2015 Author Report Share Posted June 6, 2015 Would it be easier to get an obd2 doner engine and swap over the engine, loom etc?The engine in the car was coming out for a rebuild and clean anyway? Link to post Share on other sites

Reaperx 181 Posted June 6, 2015 Report Share Posted June 6, 2015 Might be easier for you to get full engine conversion as yours has a dizzy but mine is the late obd1 with coil pack. The. Once you have done the swap recoup some money back selling the obd1 setup. Link to post Share on other sites
Cooz93 66 Posted June 6, 2015 Author Report Share Posted June 6, 2015 Was it just a case of plug and play after that then? Just swap out the engine harness and ecu etc? Might be wrong, but is it true the obd2 cars produce slightly more power? Link to post Share on other sites
Reaperx 181 Posted June 6, 2015 Report Share Posted June 6, 2015 I have heard a few people say obd2 makes a few more bhp but not sure. It has a lot more control options which makes it the better choice to run a turbo setup with. I haven't actually fitted mine yet due to not having the time and space to do it. from what I have heard its all just a straight swap. When I do get chance to get mine swapped over will be fitting a spacer gasket and turbo manifold so half of the engine bay will be coming out anyway. Link to post Share on other sites
Cooz93 66 Posted June 7, 2015 Author Report Share Posted June 7, 2015 I can't see why it won't he straight forward. Changing basically everything engine control wise. Hopefully I can source one now that isn't crazy expensive and has all bits on it! Will update if I do:) Cheers! Link to post Share on other sites
Cooz93 66 Posted June 8, 2015 Author Report Share Posted June 8, 2015 (edited) Alright.. Found a guy selling an obd2 conversion kitWhat it has..Ecu (021 906 256)Loom of some kind. Poss engine. Transponder and keyMaf housing, airbox etcEngine coverBelt tension(guessing bolt?)Inlet manifold and throttle bodyHowever he says the manifold is from a 2.9 vr6 synchro? But still says it's obd 2? And also when looking at conversion guide that ecu number doesn't come up? It seems like he has all that I need, but will it all work? Edited June 8, 2015 by Cooz93 Link to post Share on other sites
Mk3highline 287 Posted June 9, 2015 Report Share Posted June 9, 2015 If it's the 2.9 synchro inlet then that it self is worth some pennies as it flows more than the standard obd2 iirc Link to post Share on other sites
Cooz93 66 Posted June 9, 2015 Author Report Share Posted June 9, 2015 So would you say £300 all in is a deal? I'm guessing the manifold would be £100 on its own? Ecu £50? Loom £50? Then the airbox maf etc. Seems an alright deal? Link to post Share on other sites
Reaperx 181 Posted June 9, 2015 Report Share Posted June 9, 2015 I paid 100 for my obd swap I got ecu, wiring harness throttle body maf lambda basically everything except the manifold. Link to post Share on other sites
Cooz93 66 Posted June 9, 2015 Author Report Share Posted June 9, 2015 (edited) Bit of a bargain! Did you get the upper timing cover? If so have you got a pic? Not 100% sure what I'm looking for, also then tensioner? Unless you won't need to change it because your already coilpack? Cheers:) Edited June 9, 2015 by Cooz93 Link to post Share on other sites
Reaperx 181 Posted June 9, 2015 Report Share Posted June 9, 2015 Don't think I got it because mine is already coil pack. Will see if I can dig it out of the garage it's buried deep somewhere under my interior and turbo bits. Link to post Share on other sites
Cooz93 66 Posted June 9, 2015 Author Report Share Posted June 9, 2015 That would make my life alot easier. Cheers Link to post Share on other sites
Cooz93 66 Posted June 11, 2015 Author Report Share Posted June 11, 2015 Think ive sussed out the upper timing chain cover, where the cam speed/position sensor sits.. But as for the tensioner? unsure what difference between obd1 and obd2 on this.. Link to post Share on other sites
Cooz93 66 Posted June 12, 2015 Author Report Share Posted June 12, 2015 Taken the plunge and paid the man for that kit with everything in it. After a few messages I'm confident everything I need is there, so there should be no messing around! Little bit expensive but will make things alot easier! Link to post Share on other sites
Cooz93 66 Posted June 13, 2015 Author Report Share Posted June 13, 2015 Think all I need now is the camshaft Speed ring, 'hall sender' I think it's called?Part number 021905163? Can anyone confirm these differ between obd1 and obd2, and where I could get one.. Link to post Share on other sites
Mk3highline 287 Posted June 13, 2015 Report Share Posted June 13, 2015 I got one from TPS for about £15 Link to post Share on other sites
