Lito's MK4 GTI

[Lito]

So I got the cts fmic on Thursday. Had the go about modifying the charge piping a little but nothing too serious, had the boys at 999 automotive weld it up for me and I'm really happy how it turned out.



2" piping next to the 2.5"


It's a lot harder trying to fit 2.5" piping in there!


... Almost there....


Some awsome branding that no one will ever see


Back together and going for a test drive


Was dark by the time I got the bumper on


I moved the core about an inch down from where it's supposed to mount so it'd fill the bumper and get more are flow so some of the pipes were a bit tough to fit, especially on the cold side but I'm pretty happy with it. butt dyno says it works, even in 35 degree heat it didn't have a hint of heat soak (neither did the PWR core to be fair), seems to have free'd a few extra ponies with the larger piping though.

Looks good mate, any more lag?

None at all that I can discern

Serious, why would you sell it and that cheap ?

Haha I dunno, had it for like 5 years and kinda thinking of a change. But I'm more than happy to keep it. It's pretty much finished now

[Lito]

So i decided to keep it and turn it into something a little special. I ripped out the old me3.8 ecu and wiring loom and replaced it with a me7.5 wideband ecu and harness from an audi TT. The swap was pretty straight forward, all plugs are colour coded and matched up. The only tricky part was that i had an auto loom so i had to wire in my old speed sensor. If anyone wants to do this swap i am more than happy to share my knowledge, if i can pull it off, there's no excuse for you!

What are the rough costs involved. Harness, coil packs, throttle body, DBW accelerator pedal.. What else?

[h100vw]

I think you'd have to be keen to have a wideband set up to justify the change. Also probably worth fitting the VVT tensioner at the same time.

The cost could vary a bit depending on how you go about it. One donor vehicle would be the ideal solution. Golf/A3/TT being best in my opinion. Though you could do Polo parts but the fitment wouldn't be so hot as the ECU is bulkhead mounted.

Gavin pretty much hit the nail on the head with his reply. If you get everything from a wrecked car you could do it real cheap and probably make most of your money back selling the rest of the car. I would stear clear of a polo loomas the wiring lengths and mounting points may be different. My tt harness literally clipped into all the mounting points and grounds. I had to get most of the sensors separately az the guy already sold the engine but i still put it together for under a grand not including the tune.

This is a complete list of all sensors that i replaced or added...

Maf
Map
Coil packs
Both o2 sensors
Throttle body
Accel pedal (get harness too!)
Knock sensor x2

Get a seperate wideband gauge as well, the innovate ones are like $300 and super easy to install.
Youll also have to resistor the n112 and n249 or add these systems in but dont do that.

The only thing i could think of that would make it tricky is if you have a t10a connector nearthe battery instead of a t14a connector. Apparently only really early mk4s came with a t10a connector but mine is nov 99 build and it has the t14a plug. Even if you do have the t10a plug its just a couple of wires that need repining.

Also get these to mount your coil packs securely to the valve cover


Part number 077905390 like $20 from ebay

And then how did you tune your car?

And then how did you tune your car?

Well thats the fun bit!! The obd port works as normal so it's just like tuning any car with the me7 ecu (s3, tt, polo gti etc) im running the stock maf and injectors and just staying out of boost until i get the tune done through gavin. This is where having an afr gauge comes in handy
