[black240jl]

alright i have a rb20det in my s13 with these mods..3" custom exhaust,fmic,welded ic piping,aem fpr,walbro 255 fp,hks intake and v stack, stage 2 clutch,and thats about it motor wise, i bought a really crappy boost controller off ebay it was 50 bucks and it was still crappy, it was suppose to be a turbonetics but it wasnt! the directions were backwards or the controller was, anyways i turned the boost up to 12 and the fuel psi up a lil bit, not it cuts out like 3 times when i fully gas it idk whats goin on i hate it, i jsut ordered a new turboxs mbc, maybe it will work better, also ima check for a boost leak, what do you guys think? let me know thanks, also what psi should the fuel be at when running 12lbds of boost on an rb20?? let me know everythngi thanks

it doesnt feel like fuel cut jsut little cut outs, u can hear and feel it a lil bit

spark break up.check your base timing as well as the coils and plugs.

how do you do that? what should the gap be, im thinin bout buying all new plugs, what model plugs should i get?

[Carl H]

you didnt replace the plugs when you did the swap?this really is beating a dead horse but here it goes again...ngk bcpr6es-11 plugs...common as.as far as timing, if you wired the car up correctly or had some one convert it then you should have consult...not all shops or write ups cover this. grab a timing light if you dont have consult and slip it on the the black loop of wire taped up near the ignitior and shoot the crank pulley, line up the 15* mark (assuming manual trans) with the notch in the cover and go from there...use the cas to adjust.
