N75j

[CupraUK]

Hi all

I changed my N75F for a J today. Strangely it seems to be around the other way, it has a long pipe and two shorter ones but if I wanted to fit it with the electrical connector on the front as with the old one, the longer pipe goes from being the bottom feed to being the top feed.

I put it on this way, does anyone know if this is right?

I did not get any engine lights or limp mode and its boosting quite healthy (although MUCH lower down the rev range and at less throttle)

Yes thats right. Electrical connector will be the other way round.

Boost Spikes more and holds better boost but can play havock with some motors so be carefull.

Also Reset your ECU so your car can adjust to the new Frequency control valve.

Bugger.... I did it the other way around. Kept the connector on the same side and turned the value upside down.

If you've connected it up wrong you're not likely to make more than 5psi mate....

Look at this:

£75 for an N75 valve and they won't even post it.... WTF!

Long pipe is always down into intake!

Since there are several N75 valves, would be nice to know which one (part # ) it's being sold.
Race valve points to N75 "H" version, I assume.

Is it the one you bought ?
Can you post the part #, please ?

 

[CupraUK]

I'm not selling, I was just staggered at the cost! Can't you buy them for 60 quid new?

Thanks.

I'm surprised its going as well as it is, seems fast. Maybe its because I have not reset the adaption values yet.

All revo programs here in grece with 6 speed works better on J otherwise 5 speed on N75H. (H holds more boost in upper rpm rather than J is better on overboost)

If u find an H test U will be suprised with the results.
