That has to be one of the cleanest engine bays I have seen in a long time! good job man, car looks and sounds amazing with 500nm of torque it would scare me to0! think we need a video of you killing some tires :ph34r:

Awesome work man. Everything looks so clean, that engine bay is incredible! Very motivating

Bet it's fun to drive huh. How much psi are you running and did you o-ring the block or head?

I'm pretty happy how quick it spools up and yeah over 3.5k its just lethal haha.  1st and 2nd are a laugh and 3rd is where it decides to grip (just) and go

Cheers Toby, final tune was at 16, although since driving it out the last few days I've noticed pretty bad creep so I'm gonna have to fix that somehow. 

No o-ring, Cometic MLS head gasket instead which is proving to be all good.

Interesting the torque difference between a single cam 2.5 and twin 2.5

Mine M50 made bunch more torque 640nm crank on 10 psi on 91, 1230ft/lb at the wheels and 487hp crank

Valve area may add to the result

That sounds awesome.

Do you get a performance improvement on 98 fuel?

Where did you find the half cage? does it work with interior?

Been a while since I've had an E30 coupe, but looks like the lower seatbelt sliders have been removed to make way for the cage?

Well I bought this a while back for $103 lol.  Cage wasn't homogulated and is too small diameter main hoop to get one now as NZ motorsport rules have changed since it was done.  So it was basically good for nothing except for me to cut out and send to the scrappy...felt wrong to do but whatever haha

Seatbelt mounts are undone as I'm currently cutting cage to fit properly and welding some plates on to make it bolt in, will fit with them in place when I'm done.  Quite surprised how well it goes in and out seeing as its one piece. 

The bottom of the back seat will go in, back part would have to be hacked up....But in saying that pretty sure your not meant to have any rear seating in place with a half cage, I'll probably just make some nice covers to clean up the back area
