Many of the 1000wp plus rotary (Wankel) engines worldwide use my friends intake design. They are built in Tucson at Don's shop. He doesn't ship many today, but the orders do continue from the awesome Rotary motor fans across the world.

The RX7 NA series racing club at Indy Motorsports is awesome! Cheap, as far as racing goes, and 15" racing tires are Bic Lighter like in terms of cost per lap. http://www.indemotorsports.com/site/

I've had the pleasure of owning a NA RX and a TT for a short spell. This racing group is a hoot! These cars may not have much HP, but it's kart-like racing with doors. Loved my time with the RX series from Mazda. The RX7 club locally are die-hard fans.

Many of the owners/drivers have Pineapple Racing engines in their cars-reliable with their expertise: http://www.pineappleracing.com/index.aspx

nascar motor and be done with it

 

6B rotary is wild, but rotaries are limited to three rotor 20B.

Dukes LS example is a litre too big and 100 horsepower too little! If anyone can find me a real world example of a 6 litre NA LS making over 700hp with a decent torque band under 8000rpm you win a prize!

Buick V6 is tough for sure, but 90 degree is wide. no worse than a V8 I guess. anyone know what they weigh?

You guys are doing a good job of entertaining me now.

 

There was a guy who put a GN motor in a widebody 924. I saw the car just outside Indianapolis. Wicked machine!

 

unless you use a f20 or f22?. bore stroke to somehting larger. run a huge turbo and you'd have a decent power band. and they make nice power.

 

If you want this, Don Bevers may have interest in building the motor.

Don is a drag guy, but smiles when a passenger in my 951. Talented, and his sponsor is his business. Humble guy, and my friend.

Thanks, I have had a few engine builders in the US interested in building me an engine. A couple who think they can get similar power out of an LS but not within budget. No doubt some talented folks out there but I would prefer to build my own motor whatever I end up using, unless I come across an absolute bargain. I prefer to do my own work wherever I can, it keeps costs down and is half the fun. I like to know exactly what goes into my car.

I see there is some good aftermarket support for the Buick V6.

 

There is heaps for the buick v6. Just no one in aussy likes to mod them because they're all cheap asses who think adding an exhaust makes it an absolute weapon.

The only thing i don't like is pushrod. but other than that, solid engine.

 

Forgot about seeing a Northstar 4.6 V8 on a sand rail. The engine was making around 800hp and I was told the engine internals were stock. The engine was running around 15psi, but I recall the motor was the 4.4 supercharged version modified to a twin turbo. Don't know how long it lived, but here are the dimensions and a picture of a TT Northstar on a sand rail.

The Northstar may be one of the finest engines ever designed and built in North America. Truly an awesome design with great power and reliability. The only issue that some experienced (not as common as the internet suggests) is weak head bolt threads in the block causing HG failure. Throw some larger, coarser studs in it and drive forever.

I've been to the shop and met the owner, and he's got a few dozen N* motors in various states of monster-builds, including an 800HP supercharged version in his 1930s hotrod.

I was dead-set on putting a Northstar into my 944, but it just wouldn't be CA-legal in any sense if I wanted to keep a stick shift.

 

What am I reading wrong there George. I see a V8tt with only 315hp ? Is this in n/a form before turbocharging?

 

depending on the year/model of car they were either 275 or 295hp 4.6L DOHC, then in 2003 they went to about 310 and the rwd versions were about 320HP.

then there is the 4.4 dohc version (de bored slightly) supercharged to 444 or 469hp depending on the car (XLR-V or STS-V).

also an even more de-bored version at 4.0L at 260hp.

 

Modified my friend. The supercharged version was designed for boost.
