I can only see the gm v6 being the answer. It fits all the criteria and there is major aftermarket for it. Only issue is if it fits!

FYI on the M60 V8:

Sigh... 1uzfe=$$$ for the bell housing and clutch setup.
Same with gm and ford V6/8. If using the stock trannies, then it's about how much time and fab skills. Four bangers= $$$ for good durable power. Cheap four bangers won't provide the power for the money.

It's reeeeeeealllllyyyyy too bad a I-6 isn't possible. The NA 2jzge is the answer. In all respects. $$$, durability, power, aftermarket, plenty of transmission options. Plentiful. Need I go on?

I don't know why it's "not feasible". If you're able to swap in something like a v8 then you should be able to pull off an I-6. It's just fab work and welding.

2jzge is super heavy boat anchor.

He's much better off looking at aluminum V8s like the Rover or 5.3.

5.0 and T-5. Unless its too heavy.

Take it from a Rover V8 guy, they ain't cheap. Sure the engines are, but finding the bellhousing, 5 speed, and all of the other stuff you will need is a deal breaker. Sure they are light and a 4.0 can make 250 easy HP, but a 5.0 Ford can do that for a lot less. Find a rusted out Mustang for $1500 and you are all set. Mods are cheap and productive.

You can also get a Dodge 3.5L EEG V6 from a Chrysler 300C or a Dodge Intrepid. It may be a challenge to find a 5-speed to fit it, though.

Probably not cheap, and kind of on the big side (not as long a LS1, but almost as wide and tall), but a 3.7L V-6 and 6-speed from a 2011-2015 Mustang fit the other criteria. All-aluminum so it should be light, durable, decent-sized aftermarket, used in a few European track-day cars so it has some race cred. My 'Stang makes 250hp at the rear wheels and is totally stock.

I dont see the issues with the gm motors. Find a crashed v6 camaro, all the parts are there. Or find a crashed s10 with a 5 speed and 4.3L, now that is a good motor!

Renesis? Wankles are awesome at endurance racing....

It will probably get better gas mileage while racing than the other engines, to boot.

F20c if it fits the bill. Parts are easy to find, it's well proven, and it's light so easy on the tires.

That said, you probably want something with a bit more torque so repeatable laps are easier.

There is an FC team running a 3.8 T-5 successfully in chumpcar.

In terms of mounting the easy button is a lsx using ronin mounts. You can cam and tune it to make a bunch of tq and not reach your HP goal.

What are the best donors for the 3.8?

3.8 sounds great for this application. Especially if you get crazy and boost it, but limit boost to keep power right at 250chp the whole time.

Also, a VQ35 from an early 2000s Pathfinder. Cam is setup for a lower/fatter powerband than the Z-car and Maxima variants. With some mods I imagine a pretty nice power curve for a power:weight classed car would be possible. Very light for a V6 of that output.

Of course the LSX with a cam+tune to a stupid fat power curve sounds fun.

My understanding is 95 and up. Just avoid the 3.4 as those only give you 160 HP compared to 200hp.

Most everything I know comes from this link below. I cab tell you the 3.8 chumpcar was able to keep up with our 5.0 FB on the straight.

The 13b that comes in them is more than suitable for this task. Why replace it with something that will be less reliable under racing conditions?

We're looking for 240-250 normally aspirated HP, the biggest torque number possible, a big fat torque curve, and low buy in cost for the engine.
