well i messaged johnathan, he said he would replace the plate, i have to show the plate cut up, with a newspaper next to it for the date, he will then
send a new revised plate out.
can't really ask for me than that, thanks for the advice etc.

Which injectors are better to use? Jaguar AJ30 green ones or ST220 Blue ones? Anyone know?
Thank you

I don't know the flows for the Jag version but the ST220 are 24lb at 4.5bar. On a standard engine with a decent air intake and exhaust
manifolds/system (no cats..) i found them a bit marginal with heading near 90% duty with a 12.5 Afr at WOT.
If your going for more power or a turbo  then Bosch 0280156127 fit straight in (on an St220 intake/rail any way) and are 42lb at 3 bar. I've
been running them in a standard engine for a while whilst gathering parts/building a turbo engine and with a half reasonable ecu idling at 14.7 afr /
lambda 1 is rock solid, no problems at all.

I used the standard Green Jaguar injectors, have around 15% headroom.

Quick google shows the jag injectors are 24lb/260cc at 3 bar. So at the cars original pressure (3bar on the Jag, 4.5bar on the st220) they're
basically running the same flow. Of course the jag injectors have a larger window for the pressure to be turned up to get a bit more though.
Any thoughts of boost will very quickly run out of fuel with ether set of injectors.

If you turbo the engine make sure you fit oil squirters... in fact internally all you need is oil squirters and shorter forged rods, the cast pistons
have proved reliable to 500bhp!
Siemens make an injector thats a direct fit and good for any power you might ever need.... but there are of cause Greens available that can go to just
over 400bhp and were fitted to stock nobles.

I've already fitted the oil squirters, i used the BMW valved ones. I have forged rods and pistons (bit of future proofing..in case i go daft on
power! lol). The rods are standard length, custom Wiesco pistons. Building the engine at the moment, it should be in the car in a few weeks

I'm using Bosch injectors from a Mustang,6 hole more modern injector than the 4 hole originals.
Will see if I can find specs,pretty sure they can supply plenty of fuel for a charged engine.
Picked them up for just over £100 for set of six that had only been used for testing.

They are the type of injectors needed to fit in a Jag AJ30 injection set up.
Different type of injector to a ST220 injection set up.

especially when you find the engines are good for over 700bhp reliably turbo'd 
a light flow of the head is highly recommended, allows the much more power at less boost, stock noble runs 0.7bar for 352bhp... my engine made 480bhp
on low boost 0.6bar.... I had flowed heads and cams and I don't think the cams add anything significant, so much so that my latest low power
engine i'm trying it with flowed heads and stock cams and im still targeting over 750bhp with this spec engine.
Upgraded valve strings can be bought from Piper... or any reputable noble specialist such as Mountune.
Sounds like you have been collecting all the right bits ... I also recommend single turbo, back to back testing on a hub dyne with the identical
internals the twins made 100bhp less than my single.

forgot to add, these engines run very high EGT when turbocharged... Nobles crack manifolds etc because of it, so plan to manage that with quality of
materials etc.
I run inconal manifolds and on low boost of 0.6bar I see 900 deg c EGT... more on high boost.

What size turbo are you using?
Twin scroll or single?

twin scroll borg warner... I was running a float bearing 9180 but am going to a 'smaller' EFR9176 which actually flows potentially 200bhp
more than the old one (the exhaust AR is quite a bit larger to compensate for the smaller turbine).
engine wise inlet manifold was a restriction on power on my last engine... going ITB's and a custom plenum to remove the restriction.

Is that T3 or T4 flange?
Been told by a turbo supplier that twin scroll on a V6 is a waste of money,twin wastegates etc,unless the manifolds are equal in length?
So having the turbo on one side of the engine twin scroll is no advantage?
Have you ever used a single scroll?

I haven't used a single scroll, but let me guess that it was a Garret supplier as garret don't do a twin scroll in the relevant size for
my V6.
I believe it makes a significant difference, so much so that I wouldn't even consider a single scroll even though they are cheaper. its to stop
scavenge from each bank which can occur regardless of manifold being equal length or not.
I run the turbo one side of the engine so the other banks exhaust goes a lot further under the car... despite this is spools incredibly well, much
less lag than when it had tiny twin turbos on it.

No TBF it's a Borg Warner/Holset supplier.
They said equal length headers is a must for twin scroll to be worth while .
