BKR7EIX is what I run and i basically have the same set up minus the 300ZX maf and the greddy controller (I have AVCR). And I run a bigger turbo.
BKRs or BCPs. gapped to .023 or .028.

I'm new to the rb just put it in got a nismo for and high flow fuel pump everything was working good then all of a sudden my temp gauge just stopped so that's why I'm asking. Also its making a weird clicking noise.

Dont go off the stock temp guage. Get a real guage with numbers you can read. Your going to need to tune the ecu with z maf, its differant voltage scale than stock. Stock maf should work up to 10 or 12 psi. Power fc is a good unit for under 800. Aem is great unit but twice as much.

if you need a stock s2 rb25 maf i have one for really cheap. but if you plan on making more than 300whp, you're going to need the z32 maf or something bigger

Well right now I'm just running stock maf. But also I'm having a problem with car running right with the tps if I unplug it runs fine but while its plugged and I'm driving and pushing the gas pedal its starts to cut out and then cuts back in. I already changed the tps to a different same thing any suggestions?

I use NGK FR5 s which is the equivalent heat range and type as a BCPR6ES and have no issues. Im running a topmount 50trim 63ar with fmic and freddy intake pushing 340 dailying on 12psi with no issues at all
