    Test Pipe Install, Now Trouble Starting R32 Gtr

    in General Maintenance

    Posted · Edited by eric.marsh.bnr32

    Hello everyone!

    Bit of a stupid question, did some research and couldn't find the answer.

    For starters, car specs:

    92 R32 GTR

    Power FC

    Tomei Expreme Ti exhaust with test pipe and unknown brand front pipe.

    HKS pod filters with Z32 AFM

    HKS FMIC and hard pipes.

    Situation:

    Recently i installed a cat delete pipe (test pipe) on the car and has been running great since then, accept for...

    The first start of the day (cold start?) she doesn't want to start. Ill hear the starter doing work however no go. Give it another try and once the engine catches i have to hit the throttle. car will idle all f$#@ed up for about 30 seconds then all is well? Every Start up after that is normal, just the first start of the day. Has this happened to anyone else? I don't believe in coincidence, but maybe this is.

    P.S. the cat temp sensor that was originally plugged into the stock cat is disconnected now. and I'm in japan... its 80 F/ 26 C in the mornings here, however the GTR had no trouble starting in 20 F / -6 C weather this past winter. :blink:

    Thanks everyone!

    How Concerned Should I Be? R32 Engine Knock

    in General Maintenance

    Hello everyone,

    I ran a search and couldnt really come up with any deffinitive answers. I figured I'd start a post here to see if anyone had any advice and I will be updating with remedial actions. I'll start off with the car specs and then run you through the situation.

    1992 BNR32 GTR, 108,000 km on stock RB26DETT

    Mods include: Power FC, HKS pod filters, Koyo radiatior, HKS intercooler with hard pipes, ORC twin plate clutch.

    The other day i took my car past 6000 rpms for the first time and the cat temp light flashed rapidly. after some research i learned that the powerfc will flash the cat temp light when there is a red flag for multiple reasons. One of them being engine knock.

    I changed the display on my powerfc to display engine knock and found some disturbing results. At start up, the fc will read a high of 30 knock. After start up ill clear the display and at idle it will show knock between 1-8. normal diriving up to 3500 will show 8-15. 4500 will show 20-25. at 6000 it will show 61. My power fc is set flash the cat temp light at 60 nock so that would explain why it was flashig.

    From my research I've learned that the Powerfc is not the most accurate device in displaying knock, and should only be used to give a general idea. I guess all im asking is what do you all think of this? How concerned should i be? I would rather have ZERO knock lol.

    This weekend I will be compression testing the engine to get a better idea of where i stand. Hopefully the results wont be to bad. As long as its not to bad (155-175 psi on all cylinders) i plan to baby the car for the next two years and save $ for a new engine.

    Any thoughts or advice is welcome. Thanks guys,

    -Eric
