Going to clean up wiring now and figure out vacuum lines for the RRC.
Clutch next week with shifter box and cables and RRC on and painted black. Then hopefully my toda parts land the week after so Adrian can install my sh!t and start tuning.
most of you know that I have purchased drag cartel 2.2 cams with toda valve springs. Which meant I needed a toda tensioner and Toda fd2 oil pump.
Well after a lot of talking with Adrian he has convinced me to do this...
It's an RBB yes RBB head that has been ported for maximum air speed.
Adrian is good at head tbh
Out goes my z4 head. Nothing is wrong with it. The RBB is just a better head to port for the power I'm going for.
May aswell add Compression when the head comes off.
Also Needed Arp head studs for when the head goes back on.

So these are RRC fd2r 11.7.1 pistons with rings ordered from japan. Zi and Yonas yet again helping me out. Thanks again fellas
Also grabbed a Spoon head gasket that's rated to increase the comp an extra 0.3.1
So that's happening and beginning as of Wednesday.
Still waiting on the toda oil pump balancer shaft delete kit and the toda valve springs to land this week. But the head needs 5 days as it's getting sent off with my other head bits for servicing etc...
RRC manifold is on and car is driving well, my new clutch is amazing and the 4.7 final drive I think will be perfect for this setup.
Now the long wait. It's all out of my hands as of weds.
That's an awesome update. Exciting stuff coming up for sure. Damn Adrian and that go fast crack pipe addiction he causes... lol.
Definitely keen to see what this combination achieves.

Nice collection of parts! It should be really brisk with a bit more compression and cam .
Thanks buddy. The oil pump that's coming in is going to help the power aswell as it's deleting the balancer shafts on my current setup now. The RRC mani should help out abit too.
but whats the go with the cast pistons? not keen to go >12.5:1 CR?
more compression is free power!
Would love to go higher.. But. 12.5.1 means engine and box out and block sent away.
With these they are the highest comp pistons you can get from factory, it bolts up and clearances are identical to my Z4 pistons which are 11.1.1. The gain with the spoon gasket will bring it up around 12.0.1.
This means my head and bottom end come off and the engine and all the other stuff stays in the bay.
The bottom is basically coming off anyway because the oil pump balancer shafts are getting deleted and replaced with toda fd2 pump kit.
For me the gain is good enough and I'm still keeping standard internals. I'm basically turning my motor into a jap spec fd2r k20a with dc 2.2 cams, spoon gasket and ported head.
