s14 sr20det: q45 vs z32 maf and upgraded injectors - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

quantum-kid · 11-28-2011, 07:42 PM

so im new to the sr game and im looking to upgrade my maf and injectors. for the mafs i can get my hands on either one for fairly cheap locally. im running factory t28, jwt s3 cams, factory injectors and apexi fc w. commander. car is estimated at around 270hp and im not looking to make crazy power with the car as it is mainly daily driven. which maf would you suggest i get. and as for the injectors what size/brand would be ideal for my setup. also i would like to know what numbers do you think i would be putting down with your suggestion? thanks for any advice and sorry for the noob question

z32 maf dawg! they are good for up to 500whp. as for injectors it depends on yourself. hks, nismo, and tomei 555cc injectors with that setup pushing 16lbs safely will bring you to about 300whp or a little more considering you have cams. do some research bro!

It wont add more power to his setup but if he upgrades turbos later on it will allow for higher air flow.
z32 is thebest way to go.

always use the smallest maf sensor you can get away withon a street car for good resolution when tuning low torque situations.

quantum-kid · 11-28-2011, 09:01 PM

plans are to upgrade the turbo in the future with a tomei m7960 but id like to get the maf outta the way while i can for the price it is locally thanks for the fast response

colombianbryan · 11-28-2011, 10:33 PM

yea i know but with those things he can up the boost and gain more power since the stock 370cc injectors max out at about 250hp or so

+1 I have S14 SR and would like to know what TB options are available to pair with my Z32 maf and GT2871R.

Cut off stock flange, weld on Q45 flange, Port Match, Install, Tune

although the Throttle Cable might be a new issue
