One hell of a transformation Lee.

I reckon it won't be long until you fit some forced induction there, that's what I am hoping
The engine has been built to take boost so who knows what the future holds.
Thanks for the update Lee. I can’t wait for your next battle with the ring.
InterestIng stuff keep up the good work.

Like what you've done Lee and the HT goes well with rear spoiler. Didn't realise the 3.0 MAF and trunking were that much bigger, the TB must be larger too. All makes sense now how it helps get more power from 30lt.
Great work and great write up.

one of my favorite z's on here and just keeps getting better and better. learning a lot just watching and if I was over there, I would be helping.
Legend, I love how you managed to squeeze that in between becoming a Dad. I guess the little one needs some proper wheels to roll around in and the wing makes a perfect pushchair handle 
Very keen to feel how this goes- all that 3.0 torque with a low ratio diff should be fun!
For downforce I’d suggest making your standard bumper into a ‘trackday only’ bumper - the bigger air dam give more air but probably more downforce? You can also whack a great big splitter that will be good on the ring but absolutely terrible around Basingstoke on it and then swap over as needed...Going by what the guys run as splitters at the ring, they tend be rather enormous and low!
Ps have you looked into rake angle - the rear tends to squat when loaded and accelerating which might impact things?
Might need a more nose down attitude (but not so much that you upset the weight balance too much from front to rear)

Re the pops and bangs - now I’m wondering the same about the map- I asked the guy about pop and bang maps and he said he wouldn’t do it to his own car when I enquired.
So I believe he didn’t do it to mine as he said he doesn’t (and I didn’t ask for it). But it pops a lot on the overrun now and more so since Lydden (but not as much as your 3.0si - that was tremendous!)
Wonder if it’s because I have the map and no manifold that it’s expecting more air than it’s getting - was your perhaps restricted by the smaller MAF and now with the bigger MAF it will be ok?
Ive also read that apparently pops can be made by running the engine leaner, not always by dumping fuel - something about the air mix when lean making it more ‘explosive’ hence the noise...

Just a small update for those who arnt in the loop. I managed to diagnose why the car kept shutting down cylinders and running rough. As i first thought it was something very simple, due to the nature of how I've got the engine setup I had the Lambda probes plugged into the Pre sensors which i have disabled, they should of been plugged in the Post lambda plugs so once I swapped them round the engine came to life. I've ran her for the last 1000s miles with no problems. Onto the next thing to fettle.
Common with the M54 engines (2.2/3.0) they have a very bad redesigned piston ring setup, this results in alot of blowby and resulting in high oil usage. The CCV system on these engines are ok at handling smaller volumes of oil/vapour but not so with at 10 years + in age. So the one know fix that stops oil usage overnight is to fit an oil catch can. I've ordered the bits so watch this space.

You forgot to mention how damned good it drives now!
I was going to make a testimonial page
Is that an M pace car lads
Glad to hear it’s running right at last, wonder how it will stack up against a 2.8 with the same diff 
was kinda expecting you to post up ‘fed up of chasing misfires so I’ve dropped a v8 in it over the weekend‘

Is the oil catch can a replacement for the CCV or is it in addition to? I'm looking on your photo for a diverter tube from your rockerbox feeding both but can't see one so I guess it's a replacement? Nice job lads

Correct, so the oil catch can replaces the CCV unit. The CCV body has three connections, one from the rocker cover, one to the inlet manifold and a drain line to the sump via the dipstick. You blank off the dipstick drain and use just the two other lines as your in and out on the catch can.

Not used my 2.2 yet but might just do this mod anyway. Seller told me it doesn't really use oil anyway. Had a look on the bay and they're dirt cheap, all types from 'boy racer blue' to oem looking black. So no smokey exhaust tail pipes as I've seen when following a 2.2. Thanks for the info Lee.

Careful with the Ebay catch cans, most only have a baffle. Look for a can with a filter and baffle.
Any suggested suppliers Lee?
