Stock v.* Stock, which motor is better in the long run? Is the series 1 SC faster or quicker then a series 2 NA?

torque is higher on a series I thaan an NA. depends on the shape of the Series I sc, it might just blow the Series II NA doors off.

In the long run, the Series I SC is better. The SC is very strong and will last a long time. The NA does have that intake problem on the Series II, so that might kill it in the long run.

The Series 1 SC torque is higher than 230? What about HP?

Second question is it possible to mount a Series 1 SC to a Series 2 NA Tranny? Jim allready told me its a no go for the series 2 Sc to Na tranny.

You can mount it to the same tranny ALl motors have been on the 4t-60 so they obviously all work.

The Series II n/a has a flatter powerband, and a relatively better high RPM performance. Going from a L36 to a series II L67 would be the easiest for you contrary to what you've heard.

So all cars have used the same tranny before without any problems? L67 II would be the easiest then. Hmm, besides a new cluster gauge, do I have to worry about anything else with the car, like computers or the shifter inside the car? Anything at all? If its fesable then I am going to look at getting a L67 in a few months.[/quote]

You'd want the whole setup though for the easist working. Tranny, engine, computer setup. Harness will probably be involved as well.

I beg to differ. A NA motor will NOT have a flatter powerband than a SC car. The SC flattens out the band considerably.

Like Jason said though, you'd be best to swap the engine, trans, pcm, and entire engine wiring harness. By the time you did that, though, you could have sold your car for an SSEi for less money.

Oh, ok. If changing the tranny is recommended then ill probably let this project go. I could get a new series 2 na, and buy one of those performance packages from Intense...? That included new cams and rods. That would be cool, wouldnt it? Im looking at spending around a grand probably more, for some serious power to my engine without buying a new car and tranny. Any suggestions anyone? No nitro though.

I was comparing the L36 to a S1 L67 will, he'* got relatively better top end performance, not better. More headroom too with a series II motor.

Have you seen what i'm doing to my engine? I've picked up a spare L27, and i'm taking the Heads, lower intake manifold, exhaust manifolds, and porting, and polishing the crap outta them. Getting a custom cam regrind, (they grind your cam down for shape, you get longer rods to compensate) with lightweight pushrods from summit racing.

And then i'm trying to setup a much larger Throttle body. Some guys on Club GP have gotten Northstar TB'* to work on their Series II rides, and the Northstar is the same size as the LS1 TB.

You don't need forced induction to make these cars fast.
