Fuel pump upgrade advise with nitrous please

[uk blowers]

Hi,
I have recently bought a NOS 05115 dry 75 hp kit and realise I must upgrade the fuel pump before I use the spray because I am already
somewhere near 300 bhp ( crank ). I would like to eventually upgrade to the stage 2 150 hp NOS kit ( AODE won't take it at the moment )

My question is this.......if I upgrade to a 255 in tank pump now, will I no longer need the external fuel pump that comes with the
stage 2 nos KIT upgrade. In other words can I just use the jets and shims from the 150 hp kit and the 255 pump will handle the fuel requirement

get the 255lph fuel pump and then upgrade injectors to 24lbs or 30lbs (make sure you also get the re-cal maf too)

i have a 255 in-tank and when i did nitrous over the summer i put a t-rex inline pump on just for that little extra security, i would believe you wouldnt NEED it, but its alway a good thing to have and since youre getting it anyways you might as well just throw it on, and like he said bigger fuel injectors if you dont already have em and if it were me id get 30+ lbs injectors

A 190 is sufficient, if you think you might boost later you might consider doing a 255 or a 255 high pressure (gss 340).

Thanks for the replies...........boost has always been on the cards so I guess the 255 fits the bill.

Car is off the road now until spring but I do have 24 injectors and Granatelli maf waiting to go in. Tuning is going to be a nightmare
as nobody in the UK is set up to tune these cars. I have recently bought a PMS but have heard lots of stories of people having
problems using it on 94-95 cars. I intend keeping the standard cam for now to help with tuning issues.

There will no doubt be some fun in the spring !!!!
