hey my dad and I are looking to buy a supercharger or a turbo kit for the s2000...some kits that ive read say that they put out 100 more hp... now are they really that safe and what will my 1/4 times be afterwards? also how much psi stock can it hold without blowing the motor? thanks, mike

seems high 12's are common.

I think the Comptech kit puts out 5 psi. The S motor isn't ideal for forced induction due to the 11:1 compression ratio. Is it safe? Yes, IF AND ONLY IF you tune it right and don't get greedy on the boost. The more boost, the more power, and the greater chance of detonation. Controlling detonation is the tricky part. Now, it is SAFE, but the motor will certainly wear out much faster.

 

you can easily slap on either the vortech or comptech SC kits and be done with it. Like any other car, it wont last being abused. The setup out of the box is fine, but it can be perfected for better drivability, power, and safety via a standalone engine management and tuning.

 

is there anyway or anything to lower the compression with aftermarket parts?

Thicker headgasket or Pistons.

when you open up that can of worms, you're going to be spending a lot more $$$

 

tru... so with I/H/E what 1/4 times would you get? and is NOS a good idea?

you wont be fast enough to justify the $$$ you put into the car. If 1/4 mile times is the only thing you care about, look at a different car.

 

hmm i was just looking for high 12s or low 13s and i already have the car buddy.

in that case, there isn't much you can do get the SC kit first with a stand alone engine management, have it tuned. See what you think, have a few runs at it, be sure to have an higher clamping pressure plate and higher friction disk in your clutch package. If the car is still too slow, upgrade the ring and pinion gears.

 

Will a S/C pass California's emissions? Thanks

 

i believe that the comptech and the vortech kits are C.A.R.B legal

yep, both are emissions legal

 

Why don't you spend some money on lower cr pistons like 8.5 and then boost the hell out of it with confidence of power output.

First thing to do is learn to launch the car. Go to the track and see what you run, then come back here and let us know. This will help figure out what you will run with what.

 

may i will do that and bahahahaha no emissions over here

 

no emissions in FL?? ahhh luck ***... they are strict as hell here in VA.

 

do you guys have any 60ft times with s2000's? also does comptech or vortech offer pulley or is that another company? how much would 3 or 4 psi make?

 

i am not sure what 1/4 times would be,(not taken to the track yet...) but my buddy has everything comptech makes for the s2k on his.... i mean everything, his car should be the comptech poster child.....

he runs race gas all the time... w/o a cat

drives the car only on weekends

he also just installed the richmond final drive, and the 04 comptech pulley for more boost.....

not in richmond! none here! gotta love it.

 

Does anybody know what would be better to throw on an S2000. A turbocharger or a supercharger. I live in New Mexico and my elevation is pretty high (7,000ft). Would altitude have a factor in this?

There are loads of threads discussing what you are asking, just have a quick look. The opinion seems to be divided, but the basic conclusions is this. Turbo's produce more power, but cost more to achieve. If you arent going to go over about 300whp, then a super is ideal. The bottom end seems to allow about 5-7 psi of boost safely which is about 100bhp. Yes, the altitude will make a difference, but you can up the spin rate on the charger to compensate (you wouldn't need to on a turbo as the wastegate actuator would be set at certain pressure, no matter what the turbo spin rate was). Just remember, that if you are going to drive downhill(!) to change to make sure you don't detonate.

Can sombody please chime in on this? Ive been around F/I for a lil while now and have never heard of this... Q me in... where are you Mase?

D

 

Which car has better times s2k stock or the RSX's stock...?

 

S2000 by far. stock for stock the S2K is a low 14 second car. The RSX is a mid-15 second car, low 15's on a good day.
