Don't mind the Predator carb
I have a Holley Dominator EFI

The LS series Aluminum block engines weigh within 3 lbs of a 13B rotary turbo engine when you factor in the weight of the turbo plumbing. That;s why the LS is such a popular swap into last gen RX7's. Handling isn't affected as nose weight doesn't change.

Really?

I heard the new 3.7 V6 mustang engine is pretty light all aluminum, and it has surpassed 400whp on stock internals. That could be easier to make it work with a glide than the 4 cilinder imports and the rotaries

Really?

Yep. Have done this swap more than once for others. 13B, while having a soft spot in my heart, is unreliable in stock form at elevated HP levels. When they blow(not if)an LS makes more HP stock to stock and is unfathomably more reliable once you turn up the wick a little.

Unless you wanna go into the rotary and do some upgrading. But that isn't what you posted.

Would have thought that engine would weigh in the 250 lb range.

Must be made of Mercury.

High compression VQ35 will get you there pretty light or turbo it and have a good bit more power.

 

[roman_back]

id try the Mitsubishi 4G63, just make sure u get a 6-bolt and rock out.

 

[quadriplegic]

what about the 3.8 Buick V6? Maybe

 

[octanehuffer]

5.0 Coyote. 444 lbs 412 hp and can deliver thousands of passes

 

[Dave Burns]

My thinking as well. 400-500hp recipes are out there and not difficult.

 

[dropstep]

turbo honda b series, but for that kind of power im not sure it can be cheap. 2.3l turbo ford. once again for the power im not sure it will be cheap

 

[quadriplegic]

i think an iron headed combination long block will weigh around 400#

 

[slow87GT]

ecotech 4 seems like kind of a no brainer

 

[badss540]

Did you ever think of losing weight, that might get you 20 to 100lbs, depending.

 

[Badbascom]

Buick 215? You can get them out of most landrovers in Junkyard, Im not sure how much it would cost in parts though to make that much horsepower.

 

[JOHNBOY66]

Turbo charge a 4200 Trailblazer I-6.

 

[Blownv6]

How about an all aluminum stage 2 Buick v6 with kinsler injection out of a midget USAC car, dry sump , stainless headers etc , etc. ,etc. that makes 390 HP easily. I just happen to have one!!! Mike

 

[Hot Rod Todd]

Nissan CA18DET. Yeah its rice, but they seem pretty reliable under decent boost.

 

[turbonos56vw]

I'm a VW/Chevy guy but I would say the Subaru turbo flat four out of the WRX or the VW Jetta turbo 1.8 five valve. Either one of those will last thousands of miles at the 400 HP mark.

There is a guy in Sacramento with a bone stock VW 1.8 engine in a bug running low tens, all he did was put a bigger turbo and a draw though 4 barrel carb on it.

 

[Blue93Dakota]

Probably not cheap, but cool as hell.
