SEAT Ibiza Cupra 20VT Build Thread

[ibeezer]

Thanks for all the comments guys, seems the stealth look was the way to go. I like it a lot, i think of any excuse to go to the garage just to perv at it. Blacked out intercooler would look good but the thought of taking the front off again..nah.

I see this thread hasn't been added to for a while. As a Cupra owner I am very interested in this car. An update would be good if you have the time.

He has moved to Canberra but the car is still driving around and has been Tuned recently and engineered.

Update Dave?

Tuning the QPeng ecu is so stoneage compared even to Microtech. Even the guys at QP in England couldn't provide the tech help and they don't have a tech manual.The problem with overseas stuff is there is nearly no support.An Autronic SM4 would be the go.But in the end after 20to 25 hours of trying to figure out the backwards way they built the ecu we managed to get 93.6 KW's at the wheels from only 10 to11 psi from a 110KW at the fly engine.And it stops and turns very well,almost feels like a Golf 1 the way it handles!

**** me dead matt - amazing your vr6 scared the **** out of me so this must be quick! seriously thought i was going to die in the biza! wow stunning work matt another quality conversion!

Loon there is no reason why a black intercooler would not cool just as efficiently as a silver one, its the air flow through the intercooler that cools the air and i dont see black paint getting in the way of that!

Don't be silly. Of course it would. Any sort of coating, whether paint or anodisation, will reduce heat transfer capability.

Not enough to worry at this level of tune.

the loss would be minor in any case

You're right The turbo is far too small to generate the heat required for a more efficient intercooler... Hence why the standard side mount is spec'ed and works fine for most applications (and it's still less efficient than a front mount with a lick of paint!).

[DVR68U]

yeah ive always heard that paint will make very little difference to heat transfer. i used to hear about it all the time will beetle motors with ppl painting or not painting their barrels on the motors, atleast when you paint steel or alloy it wont corrode. also a polished surface vs a ruff surface etc etc. ive even seen studys and it was very little difference. i would think other benifits would well out weight the heat transfer anyway, like not letting the cops have a reason to pull you over lol. nothing like a big shiny intercooler to get a cops attention. then youll have to pop the bonnet, and being the mech's they are im sure they can find something illegal lol
if i was dave i would paint it black in a sec.
cheers brenton

Bit of an update, Dave has been through about 4 sets of wheels, here is the latest.
What do you lot reckon??

[Bboy_Sparx]

Yep I like that

[Mrk_Mickey]

Yeah they're nice the car has the same sort of shape as a polo because it's compact and round-ish so it works nicely!

[jayjay]

hahaha. it's a fair sight faster than a polo gti too...

come to think of it, it's like a 20vt polo gti minus 100kg stock.

thank you dave, these wheels are a lot better than the early style mk4 gti wheels.

[Golf Loon]

thank you dave, these wheels are a lot better than the early style mk4 gti wheels.

Yeah he only bought em for the tyres, I have been trying to persuade him to keep the polo ones and not just put the tyres on his gti wheels.

The offset is awesone with the pogo wheels.
