ls question
 

so all this talk lately about ls motors has got me wondering, what would it take to get a ls motor in a fox in the 5teen 5.20 range

............
 

I would think around 1100-1200 rwhp....

depends on the LS motor..

A well built 550hp ls plus 300-400 hp nitrous should do it in a typical race fox body @ approx 2700lbs I think. I have been 5.50s with a raggedy windsor and a plate that would just barely make 700 on Tutens dyno

Ask Bad Bob!

I assume this is for ultimate street. 6.0 h/c/i 300 shot nitrous, Nitrous converter and your 275/60/15. You might need cubic inches, but not much.

turbo or nitrous?? what's the weight? It would be easier with a turbo. a higher compression 370-408 would do it on a 88mm or so turbo with a 245cc or larger head, thats considering the block has larger diameter head studs, etc..., the stock 4 head bolt blocks can handle 1200 or so rwhp with a spot on tune

a nitrous motor would need to be larger, more in the 420-460" range, on a 6 head bolt block (LSX block, ERL Superdeck, or a RHS Block), and a good bit of compression, with not too much gas on top should get you there.

most of the nitrous guys in the 4's are running canted valve mozez headed 6 bolt blocks with a good bit of spray or a 88-9x turbo.

a head cam intake 6.0 with a 300 isnt going to run 5.teens in ultimate street trim, maybe at 2000lbs

Back halfed miata?

There is other variables as well for that class. I know what i plan on running in that class but wont be teens. I know roughly hp. I bet you can go 5.teens to 5.2x with 402 ci

HYHD!!!!

Get an lt1...

i would personally say i dont think its worth all the work to switch. sbf has proved to work pretty well with the right stuff like any combo. you could have to switch bell housings if you have a glide, new motor plate and stuff. thats just what i think. oh and ls stuff isnt the cheapest stuff when you get away from stock stuff!

408 ported l92 with 400-500hp worth of nitrous.

ton o spray

Im with Robert on this, Josh your shit is riding out I'd stay Ford!

Sounds familiar. I'd like to go 5.90s one day.

Me to tyler

Anyone else think about putting a steak on the headers when you see engine dyno videos?
