Hey, if anyone is on here. I have decided not to use this 99 WRX as a donor as a loom merge is going to be too much and I think too likely to have issues. So I will wreck or sell on that car and am looking to go the way of the four plug ECU with a view to later on using a link. What I would like to know is why can't I just use my BG5a TT inle manifold? It looks to have the same IAC valve and throttle body, grey injectors like the WRX, same shape and size MAF and I have heard I can use the loom from it. So what, if anything is stopping me using it? Cheers, I'm hoping someone can answer me.

I also found out the 99 WRX diagram I found was for an NA so if anyone has one of those that would be greatly appreciated as well. I probably need the WRX manual more as I plan to strip that loom first. Cheers

Hi all. I'm looking at doing a single turbo swap into my BG5a GT at the end of the year. I have bought a 99 WRX for a bargain but now realize to do this swap I will need to do a wiring harness merge. For this and for research I have been searching high and low for a 94/95 GT FSM with wiring diagrams in it. I have found one for a normal legacy and a 99 WRX but can't find one for the TT anywhere! If anyone could has one or could help me find one it would be greatly appreciated. Cheers Josh

Ok, so I bought myself a 99 WRX for very cheap today that I plan to use everything to do the conversion on my BG5a. I was sure this was the model to get but now I realize that this is a version 5/6, not the 3/4 that I am told that I need. I didn't get to look at the ECU to see how many plugs it has. The only thing that twigged me that it was different to what I need is that it doesn't run the old style large (coloured label) AFM that the is talked about on here, it uses the modern one that just bolts into the pipe. I had bought this as a whole car as I thought a whole loom swap might be the go, but how compatible is it going to be with my BG5? And if I do do a full loom swap and drive train swap what wont the new loom talk to in the BG5? I thought I had bought the right car to do this the least painful way but now I feel a bit bummed out. I can use heaps of the parts off this car and all the single turbo stuff but I thought this would be all I needed to buy.

Thanks for that. It's all just ideas at this point as my TT is really nice to drive although VOD is very annoying and it is pretty slow. If it blows up or rod knocks which I'm sure will happen at some point I would lay it up and do the conversion. Cheers Josh

Hi Im new to this forum but I have had a BG5a Legacy GT for a while now and am contemplating a tingle turbo swap. Im all good with the mechanical stuff but the wiring sounds like the hardest part, particularly because i have the four plug ECU and it sounds like I should change to a three plug. Given the the four plug to four plug swap sounds a lot easier would it be possible or advisable to go for something like a Link G4 WRX V1/2 plug in ecu? It says it plugs straight into the four plug loom and then I wouldn't be limited by the factory ecu. I know it would be dearer but it it might save me a lot of time and heart ache in the end. Has anyone on here gone that way? Cheers Josh http://dealers.linkecu.com/WRX2Plus
