Next year i plan on putting about 5-7k in my S2k. I already have exhaust, intake, some audio and video as well as some SSR GT1 rims. My question is, how can i go about achieving 300 NA HP, as i don't want to complicate things by going the SC route. I may if it comes to that, but what about all the spoon High compression parts, the new spoon and toda cams, the throttle bodies. Is there any way to achieve 300 HP using these parts? I also plan on replacing my clutch, and flywheel, as they get weaker. Lastly, if it was possible, wouldn't it then be possible to achieve 420 using a vortech kit? Just some thoughts.

I guess you mean 300 at the crank... I'm not an expert on the subject, but if it was possible it probably would have already been done.

 

Engine comes pretty well tweaked from the factory. Do know if it is possible. What I do know is that the Spoon F20C makes 265bhp and revs to 12,000!! As for the price... think of it as a dollar per rev.

I'm trying dammit, gimme some time! (just kidding!)

But seriously, if you're going FI, I would go with low compression pistons to up your boost rather than hi-comp. Hi-compression would not only cause troubles for FI, but I think would also minimize the gains you're expecting out of it.

 

I know its possible to run NA 300hp at the wheels!! With the right combo of bolt-ons, high compression internals, high profile cams, headwork, and a AEM EMS and lots of tuning!!! The only problem is the price you pay for the power. At what you pay, you can have the speedcraft kit fully tuned putting 340 at the wheels plus a few extras But if you are a hard core NA person, than its more of a philosophy then anything else. The truth is FI will always be cheaper when you are going for big gains! But if money is no object, and you wanna stay NA then I have a few ideas for you(pm me if you wanna know)

If money is no issue......then can i have some too

Good luck

 

The only way to get 300 HP to the wheel, would be to redisplace your car at least 2.2 liters, with cams/shafts/pullies/header/single exhaust/Vtec Controller.

Cams Gears= 5-10 to on NA car
Cam shafts =Up to 15 HP on a NA car
Header= UP to 5 HP
Exhaust= Up to 5 HP
VAFC= Up to 10 HP

2.2 Stroker Kit worth about=20 HP
Port and Polish estimated =30 HP

There you go...
NA HP Gains

 

Doesn't owner of J's racing have a built engine that makes around 300 HP? I think the compression ratio in his car is like 13:1 though.

 

port polish may not be as much as you expected... since F20C is pretty much tuned for the most hp... so, the port polish should probabily do like 10~20 hps the most... but I could be wrong... However, engine balance, valve spring change, intake, and others could still be done with S... just don't know how much power it could put... but 300 hps crank is doable...

 

actually, getting 300 crankshaft HP is _going_ to require a port and polish, as the stock head will only flow 300 horse worth of air (theoretical). Beyond that, the 12:1 Spoon pistons, headers, intake, exhaust, and a really hot cam (think redline at 11k+) would probably pull it off. I'm not saying it's impossible, it's just expensive (altho, I think it would make for a really cool buildup). Also, I'm pretty sure it's attainable w/o the increase in displacement. Assuming you don't make any more torque (and that's not going to happen with the bump in CR, it'll pick up 1-2 lb-ft), the 300 horse mark comes around 10,300rpm. I'm thinking that w/ the target power peak to be around 11k, that'll make 320 crank HP, or around 280rwhp...

zippy...
