So I spoke with Mike Vine turbos today, a very interesting conversation, seems they still have a few parts left over including a few exhaust manifolds, mainly to suit the iron head crossflow but they believe they have a few AIT manifolds in storage to suit the later Alloy head engines.   Not sure if I'd want to go the iron head route...they are so damn heavy compared to the alloy head and even the old log head.   Up side of going with an iron head, I can get the Manifold for a T4 turbo for around $350, I can get access to a rebuilt iron head with big valves for less than a grand, and lastly I still have 2 and 4 barrel cain manifolds left over from my old cortina project, along with a lot of other bits to suit...   Shame the head is so damn heavy....

https://www.hotrod.com/features/ccrp-0603-1963-ford-falcon-futura   Something like this US falcon setup but maybe without the 17 psi boost to kill head gaskets.   I'd probably get a slightly thicker head gasket made up to help drop the comp ratio a bit, try and keep it around 8.5 - 9:1 off boost should be alright for PULP 98 on the street.

I was thinking of a gt3576r or 82r on a setup like this for the XB.   Been recommended a 2 barrel holley, but really dont wanna run a holley.

Pulsar have a bit of following  and seem to be developing forward. Luke @ Motorfab using hem on his Torana. Luke @ sema @ 6 minute mark on the pulsr Stand  

I was thinking of a toned down version of this.   The Pulsar G42-1200 seems to be extreme overkill in my case...I dunno if the 750 quickfuel would be necassary either as I'm chasing roughly half the power, but I love the idea of this car.

I wonder if the little turbos were intended for the AIT twin turbo kits as that would make sense as two of those would blow enough air to feed a 4.1.   I remember seeing lots of articles back in 80's of the twin turbo XF's and the AWD monster that got trashed in the UK.   I'd imagine those kits being very collectable nowadays.

an exa turbo on a 1.8litre revving to say 6000rpm ish probably at 7psi is probably comparable to a crossflow on 4psi revving to 4000 ish ..
is probably how they came to do those types of kits, 

they'd been a big low/mid range boost and not be too taxing on the stock drivetrain or require brake upgrades most likely. 
if they wanted to make power, they'd have needed different everything  

Maybe, the AIT kits did, I would of thought the Exa would of had a tiny turbo from factory, but who knows, dont know m7ch about those cars.   TO4 seemed to be the go to turbo during the 80's for turbo crossflow setups.   It would be interesting to see the improvement that the old Mike Vine and AIT kits would have with a modern turbo like GT3576R, I'd imagine turbo response and spooling would be massively improved.

The car's in pieces at the moment, but I can dig out the turbo, for a close look I read once, the kits used Nissan Exa turbo's or similar?

That's cool always like the AIT kits for the XE XF falcons.   Do you know what size turbo you have? Normal the kit would of had some form of TO4 attached.   I was thinking of seeing if Mike Vine turbo's still had t4 flanged manifold availible as they were well built and compact.    The other option is a 6boost manifold, a bit pricey but very nice.
