    Going Megasquirt

    I mounted a 36-1 trigger wheel to the front pulley. Very much looking forward to trying these fuel/spark values in a couple of weeks! Unfortunately the car is in another town and I don't get to it very often.. I have to be careful doing wot/spirited test runs as the stock Porsche 901 transaxle...

    Going Megasquirt

    I've also been running a Buick GN engine on a MS2/Extra. It's a lightly modified 4.1 iron block (Champion irons, ported intake, 55 inj, roller 212 cam, roller rockers) transplanted into a Porsche 914. Stock turbo and intercooler running on pump gas. No knock sensor yet. :-o Boost at ~12psi so...

    Bad lifter(s) or oil problem?

    It's working fine with the external oil crossover. No leaks or issues so far.. and all the lifters/rockers are happy!

    Bad lifter(s) or oil problem?

    Followup, since most threads die once the solution is found! As suggested, I confirmed was not getting oil transferred to the DS galley. That answers the questions of if a grooved bearing was used on the build.. it was not!! This engine is transplanted into a Porsche 914 so accessing the back...

    Bad lifter(s) or oil problem?

    I know for a fact that the cam is not grooved. Just to do the easiest troubleshooting first, I should be able to pull the DS rockers, spin the oil pump with a drill (I have the primer adapter), and see if any of the pushrods deliver oil correct?

    Bad lifter(s) or oil problem?

    I do not, the block was purchased "from a guy who had it build by a shop" out of state. I tried to go over everything before building it up, everything seemed done correctly, but we all know how that goes. ;) I did not know to look for this groove at the time. More research with your direction...

    Bad lifter(s) or oil problem?

    I did fill oil from the DS valve cover, so the pooling could easily be left from that. Like I said there's very little if any flow while running. :-/ All the bearings were already installed in the block when I got it, so I can not answer the grooving question with any certainty. Now I'm...

    Block for sale

    Also interested. My tired 3.8 is.. tired. :) Is this block only, or rotational crank/rods/pistons? If everything- stock "turbo" crank" 2 dot rods? What pistons? Thanks- Colin

    LV8 to kPa load "conversion"?

    Hi all. I am working on a project with a mostly stock GN engine but being controlled with a Megasquirt ECU via MAP controlling the fuel injection and spark based on kPa and RPM. I need to import the GN ECU spark advance table. I have the GN ECU dump tables of spark based on LV8 and RPM. How do...

    Comparing stock spark advance tables...

    Still working on the spark table, having to interpolate it down to 12x12. Also, I'm running MAP system.. I can't find a straight answer about converting LV8 values to KPA. I've seen mentioned to use KPA range 20-100 in place of LV8 32-208. But when in boost the spark won't change any more...

    Comparing stock spark advance tables...

    Thank you it looks like I can pull in way more advance than what I have.

    Comparing stock spark advance tables...

    I know it's an old thread, but it seems to be the most appropriate to what I'm looking for as well. I'm putting a Buick GN engine into another car (stock turbo, ported intake/heads, roller valvetrain, 36lb inj, pump gas), and am controlling it with MegaSquirt. If someone could re-post (or email...

    Very interested if still available.

    Champion bracket, intake manifold, stock turbo, ignition module and coilpack, and more

    If the turbo has no previous turbine contact damage, I'll take it.
