I had my 44s on my Toyota Corolla You can get one of the Facet pump that run about 3-5 psi and you will be fine I ran 2 1/2 psi on my Corolla with my .510 lift and it ran fine
Thanks on the manuels I have a Mikuni one here and Webers are way easier than Mikunis
Here is a pic of my Corolla
This is how it was before the massive rebuild going on now 45mm ITB's and a 5mm over block
