Bad_Pritt's Black Pearl II - Z4QP 3.0si

Post by Bad_Pritt » Thu Jan 18, 2018 7:35 pm

I had a warning light for the brakes recently as well as a service warning. So I got the car to an independant garage (my nephew) for maintenance and to have a look at the brakes. I got the car polished at the same time as the paint needed that quite badly. Got the car back looking almost brand new, new brake disks and serviced. But also got less good news: seems that the engine has the well-known ticking noise. According to my nephew, repairs aren't urgent, but need doing nonetheless. So next winter, the Zed will be getting open-heart surgery and I'll have the crankshafts changed at the same time, combined with a remap. In total that should add about 50 to 60 hp to the car, bringing the power over the 300hp mark, up to about 320hp. Not a cheap fix & tune though... Has anyone else done this before?

Ticking noise is normal for a car that has sat for a while. Drive it again properly and it'll go.

In the long run, the valves will need replacement. I'm not driving the car on daily basis as well, and it is a common issue on the pre-2009 Zeds. It's not urgent, but I do want to get it sorted.

Sounds like the ticking is just an excuse to release some extra horses - as said its quite normal on the si, I like your style though :wink:

Well I had to get the missus convinced didn't I? :evil:
But honestly, my nephew said it would be better to get it sorted. I'll admit it IS a good excuse for extra ponies though :D

I’m intrigued on the camshafts you mentioned. I can’t find any race cams for the N52.

The schrick listed item states N52 on searches but actually is an N54 item from what I’ve researched.

Got a lot of info from here:

EDIT!!! Just realised you said crankshaft! :oops:

He said crankshafts plural so I reckon he meant camshafts, a replacement crankshaft would not increase the power either :? (Unless it’s a stroker crank)

You're right, I made a translation error from Dutch. I indeed meant the 2 camshafts and engine valves. :oops:

In which case I’m intrigued - have you found any performance camshafts or are you just putting in new stock ones as a refresh?

I’ll be putting sharper camshafts in, well my garage will do that. :-) Not sure where he will be getting the parts from, but I’ll keep you guys posted.
