    First here is my problem, I have a y8 that the b&m fpr took a shit. I need to replace it. Don't have the money for a aeromotive one yet till next week. I have two stock honda fpr's and iam using a crx si stock fpr. Does anyone know what the stock honda fpr's are rated for? I have a LS FPR from a 97 and a stock 99 fpr. What are these fpr's rated for? Are they the same?

    Its for the d16y7 block with a y8 head ported,heads been shaved like 3 times, 3 angle, port matched intake mani,stock bottom end 100 shot wet kit, of nawwwwzzz! :) and act stage 2 clutch dx trany. But it breaks up bad at high or top end with the nitruous. It has a 255lph walbro fuel pump. It was working fine with the b&m but that took a shit cause the diapram was damaged, the hack job you have to do to install those no wonder they don't hold up well.

    well I poped a headgasket again!! Would a thicker headgasket sovle this problem? Cause iam replacing them with honda headgakets, there $40 for me since I work at honda. Just wondering if I should use a cosmetic headgasket .

    I guess when you build a cheap + fast = unreliable?

    Make sure your mating surface are flat and that you're torquing everything down properly... and that you're using new head bolts or using ARP studs.
