Foghorn is on a distinguished road
Default Lots of Mods - Engine is back in (56K ok but slow)

Well, it'* been an interesting past couple of weeks . 2 weeks ago I pulled the engine out of my car to add a few mods I'd been working on. Here'* a list of what got done;
  • XP Hot Camshaft
    Intense Oil Restricted Pushrods
    Custom Ported Heads
    105# Competition Cams Springs
    Milled Retainers
    Valve Guides
    Viton Valve Seals
    Decked 0.005"
    TOG headers welded on the outside flange to allow them to be matched to the heads
    Anodised intake port matched to the heads and milled our for Intercooler
    M90 Supercharger inlet opened to 76 MM (outlet was already modified)
    Custom Northstar Throttle Body Adaptor
    75.5 MM Northstar Throttle Body
    85 MM MAF
    4" Intake Hose
    Custom Intercooler with 8 Litre Reservoir (11 Litres total)
    Jabsco Centri Puppy IC Pump
    8 Rib Supercharger Belt and Pulleys ( modified balancer and engine mount )
    2.8", 3.0", 3.2" ZZP MPS
    DHP PowrTuner

Probably a few small items left out but that'* the brunt of it. I was out tuning yesterday in 95*F heat with the 2.8" pulley on . Almost got that mastered, have 2 degrees flash KR from 60 MPH but no KR from a standing start. I have the 3.0" pulley on now and there is no KR at all under any circumstances.

In 2 weeks time I'm driving to Toronto to have the transaxle rebuilt with all new replaceable parts, other hardened parts, high stall torque converter and 3.29 gears installed. By then the Nitto Drag Radials should have arrived.

I think it should be a fun summer. With that, here'* a few pictures;















EDIT: Added more photos;











I'll see about getting a vieo or audio of the idle :P , I have changed the idle speed so when it'* warm it idles at about 725 RPM...with a really nice lope and a bit of rumble

Looking forward to hitting the track soon!

Cheers,
