Eww and in a dynojet too, arent they rated at 240hp (crank) from factory?

 

In the same way a Miata can easily make 350 on a stock motor?

 

There's a "stock" s2k all over youtube making 700whp. According to the owner is all about the tune

 

yeah, ok, I believe all of that.

I'll take an S2k with an Endyne NA motor, please.

 

I never get to race **** anymore. No one messes with me exept Phil who can still whoop my ***....for now.

 

Very flashy car, good looking and handles pretty well, but it just doesn't have the torque for ANYTHING. It really makes it NOT fun to drive. I have to get above 6k anytime I want to move anywhere.

 

Do LSx's fit into S2K's? Seems like it'd be a pretty capable platform to put the power down...kind of like a FD but convertible.

 

There are TONS of them making 350whp with a supercharger at 12psi.
Also lots making mid to upper 400's at fairly low boost with turbo's (10-14psi)
I've seen my fair share of 500whp stock motor ones too. Don't know how long they'd last at that level, but at 400 they hold up for YEARS. I've also seen the 700whp stock motor one that was mentioned earlier.

Their pistons and rods are forged iirc.

The thing with those cars is the head flows VERY well, and the shortblock is fairly stout, so people can easily run 35r's and 40r's and have enough revs to be able to have a decent powerband and a very powerful topend. Boost is usually kept fairly low due to the high compression (11.1 iirc), but they put out NASTY numbers.

Very impressive car with boost.
Damn expensive to do it right compared to a miata though.

 

That's what the owner claims. I had my bullshit meter out when the thread come out, thus the "stock". Those engines have 11:1 comp IIRC

Oh well I knew about the torque issues but those numbers = limp dick

 

I am jealous. :|

 

I just tell him he has an rx8 with VTEC

 

Limp penius fail

 

This one is local:







Yep, the pistons are forged with a high silicone content to limit expansion and are iron coated. The weak point that most have found with boost are actually the rod bolts.

 

Mother of god, i <3 ls1 s2k.

 

On another note I barely pulled a stage 2 caliber srt4. Kid claims 300whp, not sure how true that is.

I'm probably around 190whp.

 

do i need to post this again?

he should be somewhere around that. those cars are ugly as sin, but pretty peppy..a few bolt ons + tune really wakes them up.

too bad they're fwd

 

Yeah, I actually rode in it first and thought he would pull me. Thing torque steers like a bitch, scary fwd car imo.

I need moar boost! The only reason I'm running 10psi is because I need a bigger rad/shrouding(which ill be picking up within a few weeks). Plus I'm just enjoying the car how it is for now, I like to leave more headroom. Next time I turn up the boost it will probably be to 13, and after that to 15/16, then ill be looking for WI.

 

I hazzz WI for cheap too lol.

 

They have forged cranks too, another important feature of the engine that most everyone over looks is that is is an over square engine which limits torque forces that the engine experiences. This is also one of the reason they rev to the moon. Most of you guys have seen my build, If you have not, here is the link. https://www.miataturbo.net/build-threads-57/f20c-engine-conversion-42810/. It is an F20C (s2000) powered Miata. I am in the process of putting a turbo charger on it. It is a very exspensive build, to do right. Once it is done I will share all my tuning info and dyno numbers. But 450 ish HP on an elt manifold with a genuine Garrett gt 35 turbo 14 -15 lbs of boost is easily obtainable. The rumor is that this boost level will allow a 100k of durability as well.
