Well, for $1995 you can buy a tec-II from shiv (na version)
This will allow you to raise the redline to 10k
HOWEVER
at 7200 rpm you will start getting valve float.
at 8000 rpm you will start risking your rods coming apart.
not to mention that you'll need new cams to make any meaningful power at those RPM's

You're looking at 1.7k for rods and pistons
$500 for uprated springs
$500 for a cam
$2000 for managment
plus installation.
That'll make you be able to try for those Revs, but still you'd need more work to even start making that power.
I bet if you were willing to drop 6-7k you could have a very very powerful NA car... probably not 300hp and not 10k rpm, but one that could hit 8k safely and put out low to mid 200's

No one has run at more than 7500 rpms for any extended period of time.

On one hand, you'll have a unique car.

On the other hand, you'll have a unique car...for about 15 minutes.

But 300hp at 10,000rpms (if you can keep your engine together) sounds completely feasible.

If yuo were talking turbo chargeing than you could maybe get the HP for that $$$ but not only would th RPM's your talking about prob. cost $2500 in rod, piston's and balanceing, but I would have to ask.... WHY???

Don't get me rong, I love high rpms, but I see no use for 10K. 7 or 8 sounds good though (I'm used to a 6k red line but the car pulls from around 2k till 6,300). I would have no use for a car that gets all it's power so high.

just my $.02

Its possible, but not at that price. It will be cheaper to do if you run a EJ-22 crank. The lesser stroke, and the "better" rod ratio will lower the stresses alot in comparison to the EJ-25 at the same RPM.

Biggest problem is that you will need a whole new intake manifold, TB, intake, Exaust form the Y-pipe back, new cams, head work, programible EFI, etc. So much of the parts on your motor are tuned for use at around 2-5K rpm that you basicly will only be using a stock engine block from SOME EJ, and the crank out of one of the shorter stroke motors.

Oh and it will be very torqueless below 6 or 7K rpm given a 10K rpm peak.

.........yeah its nice to think about the false promise of all motor glory when you cant afford a turbo huh? Me, im just going to wait and buy a turbo like all the other power nuts, an all motor 300 hp impreza is an undertaking for someone with a much larger budget then anyone I know has. Save one, but he already has a porsche to keep him happy.

an all motor impreza is a nice theory. but we dont have the aftermarket affordability honda has to create N/A monsters at reduced rates.

If you had a roof rack a JATOL (Jet Assisted TakeOff and Landing)goes for that price. It would give more boost than the model rockets. You might to go buy a Ricer Wing first though it would accually be used. To carry you into the air

Bad acid trip ha ha...

No someone probably just got high and started thinking they could use their bong as an air to water intake intercooler! Yeah with 100% cooling from ice water, some block strengthening and some bolt-ons that baby should do 420hp @ 9,000 rpm and about 70 lb/ft @ 2,000

haha whatever.

Don't know if I would do this. The chip messes with the timing and with the NOS kit if the timing is messed with then boom. Be careful if you go this route

Guys its NOT difficult to make a EJ motor turn 10K and make HP doing so. However its NOT CHEAP. If honda can make a long stroke econobox motor like the B18 turn 8K, a short stroke EJ-22, or EJ-20 is easy.

On the Nitrous and chip bit, you really need a chip or ignition controler to run a big shot on the motor. I certainly would not run a 150 shot on a EJ without somehting that can program out some of the timing. I also would not run a 150 shot w/o using a direct port kit which interestingly isn't much more than a normal kit. Its $634 for a V8 kit, and the normal one is around $500. I don't now what the 4cyl version would be but I think you could shave off more than a little as it uses alot less extra componets.

Paeco makes all motor engines of various stages. Prices are as follows.

A=Assembled K=Kit

2.2L:

Stage 1 168HP $3800-A $3000-K
SRE 182HP $4400-A $3600-K
Stage 2 202HP $4400-A $3600-K
Stage 3 232HP $5400-A $4400-K
Stage 4 267HP $7400-A $6200-K

Core Charge: $1000


2.5L:

Stage 1 185HP $4000-A $3200-K
SRE 206HP $4600-A $3800-K
Stage 2 239HP $4600-A $3800-K
Stage 3 271HP $5600-A $4600-K
Stage 4 328HP $7400-A $6200-K

Core Charge: $1400

Stage 1: Strickly street engines w/more power and reliability(?) than stock engine.

SRE (Super Reliability Engines): For people who plan on keeping there car for a long time.

Stage 2: For street and rallying. It is sometimes necessary to use octane boosters with these engines.

Stage 3: Racing engines. Not suitable for street use. Requires racing fuel.

Stage 4: High RPM engines desinged for SCAA sprint racing. And require changing rod bearings before each race. Also require racing fuel.

They also make 6cyl engines too.

So with all of this in mind, I say go turbo for big power.

I got some swamp land in Florida for yall. (yall, how Texan is that)

I have yet to hear of anybody running a Peaco motor. Espically on the street.

Anything making power over 7500 RPM will require a completer re-design of the intake system. Such as individual throttle bodys. The stock type designs just wont cut it at high RPM.
