Hello Gent's                   Back after a long absence from a series of unfortunate event's .All is good. Except for this PVC valve (in pic) Do not know the correct name of it Search the internet to replace it . https://ibb.co/qLS00mz4                    

I bit the bullet, ordered a PULSAR Next GEN PSR3582 XR6 turbo with the wastegate set to 11 PSI, under a grand with shipping, will need to adapt a manifold as it a T3 turbo but should be easy enough to do.   Now to collect the rest of the bits I need.   Hopefully it'll all hold together to make 350ish HP without killing the T5🤣  

I don't have any experience with Pulsar.   That said, haven't heard anything bad, and there's blokes running fast with them. 

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.
