    Thanks for the feedback - I ended up threading the hole for an M8 bolt, applying JB weld to the bolt hole, then treading in a bolt with a spacer to create a roller. Not a great solution but better than what was there.

    Split second loss of power

    in MegaSquirt

    Posted

    I am running Megasquirt 2 wired in similar to below wiring diagram with an 83 distributor and using the MAP sensor.

    Under very light/cruising conditions the power will suddenly drop out then come right back. Makes for a sudden jerk as driving.

    Took it to a track day last year and didn't have any problems at continuous WOT.

     

    As I type this I thought a deadspot in the TPS (although it was new 2 years ago when I installed MS) I'll check that tomorrow morning.

     

    Any other ideas that I could look for or check? 

     

    Thanks,

    N42 Turbo Motor Build Questions

    in Nissan L6 Forum

    Posted

    Looking for some feedback on my plans.

     

    Current setup:

    F54/P90 280zx and turbo

    Megasquirt 2 - 440cc injectors

    Evo 8 intercooler

    14psi

    3" exhaust

    Goals - 300-350HP 

    Use - 95% street car, with 1 track day per year 

    Due to too many car projects and minimal car space I need to minimize the non-driveable cars. In order to do this I wanted to use the spare block that came with car when I bought it. I had it cleaned and inspected.

    It is an N42 block, the engine builder stated everything was in great shape except the rod journals that need .25mm to get back to in print clearances.

    He has suggested re-using the pistons that came out of the block given their good condition and has given me the part number for some Hastings piston rings for the NA block as a recommendation.

    Questions:

    Is there an issue with using the dished NA N42 Pistons with NA piston rings for the horsepower I'm looking for?

    5spd front cover lip seal

    in Drivetrain

    I believe you can still get an oem seal from Nissan. It has an obvious taper to it to match the taper of the main shaft. I had a Timken seal which didn't look quite right so I ordered oem if I remember right.

    I believe your second photo is the correct way. Like I said put it in so the taper is on the same side of the tapered mainshaft.

     

     

    the 2nd photo is how the last one came out. I didn't consider there being a taper that the seal actually mated up with.

     

    Any other votes for 2nd photo?

    5spd front cover lip seal

    in Drivetrain

    Posted

    I am refreshing the seals/gaskets on my trans and when I pulled the lip seal out of the front cover it appeared to be in backwards. I've worked with reciprocating pumps for many years and the lip of the seal always points towards the fluid you want to keep in. When I pulled the seal out the lip of the seal was pointing towards the engine.

     

    Can someone confirm which direction is correct? Pictures show both sides of seal.

     

    Thanks,

    Shifter boot seal 5 speed

    in Drivetrain

    Posted

    Quick and easy question - I'm putting my trans back together, disassembled to reseal/gasket/oring to get rid of leaks, and wondered if there is supposed to be anything used to secure the boot that on the shifter:

    The factory manual doesn't show anything and there was a zip tie on it when I disassembled it. Wondering if it supposed to be sealing all on its own at the base or if others have used a hose clamp/CV boot clam or other. 

     

    Thanks

    2 ways to look at it:

     

    1. Get the latest SA 2015 or 2010 that you can. That way you're covered for any auto event anywhere for a longer period of time.

     

    http://www.racerpartswholesale.com/category/FullFaceHelmets

     

     

     

    Trade off is SA helmets should not be used for motorcycling - size of the eyeport being the usually sited downside.

     

    2. If you're really confident you'll never venture outside of things that allow M2000+ and want a dual purpose helmet (what I currently have for autox and motorcycling) get an M helmet.
