What To Do First....

[mad082]

the 34's came standard with the same bov as all the other rb20/25s, which is also the same as on a wrx (although the bolt holes are in different spots).

and the 1 intake mod doesn't apply in QLD either.

sorry for yet another hijack , but is that autospeed fuel adjuster and boost controller thing as good as the pfc (when i comes to air/fuel tuning and boost controlling)? would this be recommended as my next mod since after installing and splitdump/front pipe im now running at slightly higher boost than normal.

hey lanky71, the first mod i did to my 34 was the FMIC and pod filter (yes i know its 2 intake mods but the 34 sedan is a sleeper kind of car, cops dont care too much where i am anyway ), then a split dump/front pipe and a custom catback system (including the cat, it came to about $650 - done by a local exhaust shop); and yes, i also got a bov and placed it in the 34 auto, bascailly i got sick of it after a few months and took it off ( its also a cop magnet) .

Just a question... how'd it sound on an auto btw?

i reckon if u had to make the choice between a pod or a fmic, go the cooler. see what GTRgeoff has in his writeup on airboxes and get a good panel filter. My 2c

oh and geoff, that lock bar, good stuff mate. i love it! easy as to fit

sounded good, i had the gfb mach 1 and didn't have any of those stalling issues like other people had.

Hows it going mad?

the BOV was on the auto tranmission r34's as well? (i'm fairly new to nissan's)

I'll explain why i'm asking these questions (might not matter with newer cars, but i'll mention it anyway):

I had a mkIII supra previously (Ga70, 1G-GTE engine, Auto, used a MAF sensor not a MAP sensor like the 1JZ) and it did not have a stock BOV. I got a BOV put on next to the throttle body. I then added a cat back exhaust with HI Flow cat and a HKS superpower flow pod kit. Once that was done, did a dyno run and the car didnt perform as expected (almost worse acctually). Turns out the ECU could not cope with the now quicker and larger amount of air flying into the engine, and started flooding the engine with fuel (even had tiny droplets of fuel spluttering out the exhaust. A SAFC had to be installed to fix the problem and to make the most of the mods (got even more HP with the SAFC). After reading about it on the web, it seems that ECU cars without a stock BOV or with recirculation valve factor this in its air fuel calculations (is this true anyone?). Introducing a atmo BOV or POD kit threw these calculations out the window apparently. Again this problem plagued older ECUs, and i'm sure the r34's electronics are well advanced compared to a Ga70 supra, atleast i hope so *chuckle*.

Newer ECU or Not I'd still recommend get a SAFC when you start changing AF parts, purely to get the most of your mods.
