    Re: Running a Northstar on a LS1 PCM.

    Lol come on guys! I'm not looking for a plug and play. I can read and its pretty obvious that the N* is an engine that can't have much if anything really done to it when it comes to mods. I swear sometimes you treat new people like they are retarded. I'm pretty sure we are all here cause we like the same thing. Some of us have more knowledge in cars then others. But whatever life goes on. I did have a question about the Westers place in Canada. Just wanted to know if this place was ever able to do anything with the N* or not? If so what can they do and how much does it cost?

    Thanks

    Re: Running a Northstar on a LS1 PCM.

    Hey guys, I finaly got to drive my little mid engine Northstar powered Mazda pickup. Look on page 9 of this thread if you want to see old pics of the truck. I'll try to post some more pics and info later on when I have the time.
    I did install a single turbo just to see what this thing was going to do. I didn't run a whole lotta boost but what little I did run was awesome!!!!!!!!!!!!!!! 6lbs to be exact. I can go all the way up to 35lbs but I dont think my stock engine will stand much more than that without scattering a bunch of parts all over the road!!!! Im going to build me a good stout engine when I get all the bugs worked out.
    Lyndon Wester at Wester's Garage did me an LS1 ECM with a turbo tune. I cant even begin to tell you all what this was like. I was expecting the truck to spin like crazy but I was amazed. The tires are 235-50-ZR18 Firestones . I thought if it wouldn't spin the front end might come off the groung but it didn't. It just took off like a rocket and pinned me back in the seat without any wheelspin at all. I dont think the truck weighs much more than 2200 lbs not counting the northstar engine and tranny.
    Right now I have a 3.11 gear in the 4T80E tranny but I've got a 3.70 Im going to change it to later on. Lyndon wasn't able to get the tranny controls working in the LS1 ECM in a reasonable length of time so I went with a stand alone Power Control Solutions - Transmission Control Unit which is very tunable. I think I might like it better anyway. I can change line pressure , shift points , TCC , tire size, VSS and gear ratios and such. This control unit will let you have a performance calibration and a normal driving calibration with a flip of a switch. (A) for performance and (B) for normal driving.
    I got to drive this thing about four or five times up and down the road in front of my shop before it decided to twist one of the axles in two. This thing has an awesome amount of torque with the turbo. Im having another set of axles made as we speak. Im giong to try some 4340 and have it heat treated this time. The axle shaft is what broke not the joints. The stock Caddy CV axles are definitly not going to be strong enough. Anyone got any ideas on stronger axles?????
    I hope AJ will chime in on this one. He has a lot of experence with these engines and ECM's . I'd like to know if he's made any progress with his super charger for his Fiero to.

    Steve (AKA mazda1949)

    Nice steve

    I think you can get Strange Axles or Curry Axles to make you some.
    I have seen then done up with a flange at the trany side. They look like a VW axle or ones from the front of a GM 4X4
