The Nizpro ones are what I have had in both my XR6T's, first one was making 315rwkw and the second is 434rwkw. The Nizpro ones are of a very good quality and I believe they are used in Nizpro's 1000hp engine, which is also in BCL's car, which is making around 580rwkw I believe. Someone correct me if I'm wrong.

Howsee

Really Senna, I haven't heard of that before... I personally haven't had any dramas with them as of yet, what sort of mods have you got done and what sort of power?

Yeah mate, had a couple of blokes on here confirm. I'm running 500rwhp on the stock turbo, big dump, big cooler, built motor etc etc. They will hold 19psi til about 5200rpm then they float. My idle is suffering now too, jumps up and down after stopping...

Spoke to Nizpro about the reports of springs going soft 2 weeks ago as I only want to supply quality poducts to my customers, they have sold thousands of springs and have had 1 report of springs being bad, which the owner then had another set supplied.

Have the people with the problem ones, spoken to nizpro?

Not sure if the others have spoken to Nizpro about it, however I know the person you are talking about very well Mick :blink:

The replacement set came with shims though, so maybe they need the shims to effectively increase the spring rate
