I think you could get the hp/torque numbers to match those of the HO 4.0. The problem is the rotary would be at 8000 rpm and the straight 6 at 2000. It's not usable practical power.

 

Not enough ***** for wheelin lol

 

Any suggestions on how to wire it? Im gonna drop a 5speed in so dont care about the trans lol just want the engine to run right

 

Make it easy on yourself, supercharged 3.8 Buick. Won't have to change transmission

 

Which engine?Anything efi you will have two options use the stock ecu and have it flashed to turn off everything but what is needed to run.Or you spend a grand or two to run a standalone ecu on it.With the standalone you kinda need it dyno tuned to really run prefect.

 

Hmmm not sure I want something light and peppy thats why the 13B came to mind.

 

a 13b weights 247lbs but a ls1 is right about 400lbs.But the ls1 will live a lot longer and has a better aftermarket.The cheapest engine to make power with is still a old chevy 350.Get a 383 stroker with the right heads can push close to 500hp on a stock gm block.

 

I have to disagree, cheapest way to make power is a junkyard 5.3 swap, 280 hp, for around $800. Spend a few hundred on a cam and a tune and you're at 375hp

the bottom end in the ls series eng stock rotating assembly is extremely solid for most Street driven vehicles.

The heads flow awesome and the engine is cheap.


If I were going to swap a 13b into something, it would weigh a hell of alot less than an rx7, maybe an mgb or a triumph spitfire.

 

13b is both of those, but it doesn't make squat for power down low.

 

Ya Im looking for light and peppy not looking for 500-600hp. Just a lil more hp and tq then the 4.0. Something that would be fun to drift some and just fun to drive daily

 

did you really just say you wanted to drift an xj?

 

Ya figured itd be fun with a lowered 2wd 5speed. Drifted my 89 with 30s on it was fun lol
