Hytech RSX killing m5s and m3s
They are saying they should have 280hp all motor engine with some more engine work. 
K series ownz joo!!!! Makes ya wanna forget about the B series don't it?

I will try and answer as many questions as possible. I will check this board every night when the kids are in bed. And reply as best I can.
For the record, This was the first of many tests that we will run. There is plenty more power left to find. The cams are pretty mild but the lobe design is excellent. We feel that there is an air restriction in the intake manifold runner size, and possibly the plenum size is a little small. Also, we only ran one header of which we have two more to try. So with a few changes I think 280 will be the target number we will search for.
As for how it drives. It is pretty docile under VTEC, we did move it back up to 5,000 rpm change over point just so we could drive it on the hwy with out killing the gas mileage, When you put your foot down it pulls very hard all the way to 9,000. The acceleration is really fast and you keep having to grab more gears! Of all the fast cars that I have owned and built. This is for sure the funest to drive. To date we have put away a M5 on the freeway and a M3 on the way to work this morning. He pulled me over and asked me how big the motor was and how much boost I was running. I said it is just a mild 2 liter and its NA! He shoock his head gave me the peace sign and drove away. I think I'll drive it more often now.
I am working on pricing now and should have something by next week. I might do a cam change before I make my final desicion. I want it to be drivable and it is very driveable at 265 whp. So we will have to wait and see. The kit will consist of : Rods and pistons 12 to 1. roller cams. Ported head and complete valve train upgrade with valves, springs and Ti retainers. The springs we are using are out of the Chevy IRL motor, The are a bit pricey but well worth the longevity that we will get out of them. Intake manifold and throttle body upgrade. Header and exhaust, and ECU reflash. We will aslo be offering complete customer motors with this and other upgrades. They will run on 91 octane pump gas! If you want to run 100 octane you will make 5 to 10 hp more.
For those who have any questions just post them here and I will answer them as soon as I can. We will have the new site up and running soon, called rsx-tuners.com, you can check the pic's out there when we have them up.
The goal of all of this was to firmly plant my name into the K series tuning circle and I think we have a good start. We are also working on the turbo and screw charger kits. And some pretty cool 2.3 liter NA motors that will approach 400 crank hp.
Thanks for all your compliments. It does make a big difference when someone appreciates all your hard work.
A special thanks to Shawn, Doug from Hondata, Ron and Joe. Who all helped out at the last minute to make me look good.

A B-series can do the same... BUT, its not streetable and definateley NOT 91-octane.
Honda did an amazing job with the K-series design!!
Imagine that 280whp motor in a 95 Civic HB gutted to 1900lbs and driven on the street...!!! Now, THAT'S a 10-second monster

I've already driven one that is swapped into a 1998 Civic HB... very easy actually :-) It's a K20A but form the Japanese Type-R... 220hp stock.
Notice that this guy NEVER TOUCHED THE HEAD!!! No port & Polish.. the K20A flows like crazy from the factory!!!!
Now do you believe 300whp is possible NA on our motors?

Awesome, gives me ideas
Oh our engines? SO much potential just need somebody to unlock it.

But he says here they ported the heads
Anyways, how quick was that civic hatch in the 1/4mile, or how quick would u anticipate it to be (the one that u drove w/the k20)?

They don't port the heads.. maybe take some crud off, but definately not port... you can't expect them to have more knowledge than Honda's R&D when it comes to how the K20A head flows!!! It took people 10 years to figure out how to port the B-series heads and make power NA!!!
He probably says whatever.. and then someone tries it and the car doesn't make pwoer.. its to his best interest to keep what he does to himself!

Hytech Exhaust has recently finished testing their new performance kit for the K20A2 engine found in the RSX-S. The kit includes new cams, pistons, rods, intake manifold, header, ECU retune and a ported cylinder head.
As we were fortunate enough to be present during the tuning of the ECU by Doug from Hondata, we were able to see first hand what sort of power this engine is capable of. Now, before you skip to the dyno sheets, note that all the testing was done on 91 octane pump gas!!! And then remember that this engine is normally aspirated and 2.0 liters in displacement.
There is more to come on this topic, as we'll be doing a test drive soon and giving real world driving impressions of this engine package. But, for now take a gander at the dyno curves vs. a stock RSX-S, and a heavily modified (with bolt-on and Type-R parts) RSX-S from our good friend Ron.
Stock vs. Hytech
Hytech vs. bolt-ons.

Hytech's turbo kit project...
"The manifold is equal length 321 stainless steel , with a merge collector. It will run a Tial waste gate and Tial BOV. The turbo is a T3/T4OB compressor housing and can make up to 500HP if needed. Different internals will be necessary for power above 300 WHP. The Lamainova intercooler will sit where the stock air box used to be. The cooling system consist of a chiller or radiator mounted infront of the radiator and a small pump to circulate the water into the Laminova cooler. For those who are not aware of what a Laminova intercooler is, and what it can do, listen up. They are 88% efficient and less than 1lb prerssure drop across the core. And it will run only 10 degrees over ambient temperature. The results are very good. Since the conduit from the turbo to the throtle body is so short, and the efficiency of the cooler is so good, we should see full boost at 3,000 rpm's. The beauty of the system is early boost with complete control of the inlet temp 100% of the time. Which will make tuning it a breeze. And detonation under control with plenty of power. The kit will be complete with a 3 inch exhaust system, Inconel heat sheilds, T3/T4OB water coled ball bearing turbo , 321 stainless manifold, Tial waste gate and BOV. Laminova intercooler, chiller and pump, fuel system, injectors, And reflashed ECU. There will be only 1 kit with mutiple boost levels to chose from. Release date unknown but hopefully during summer time. "

Are you talking about Charles car? My buddy drove it and said it was real fun. I missed it by a few minutes.
And, yes guys, there is already a company that makes the proper mounts to drop it into old civics

I don't understand how they changed the "VTEC changover point" to 5000rpm.
On the iVTEC motors isn't this incorrect since there is no real changeover point like in the old VTEC?

Yup, Charles' car. I think he was the first to do it... well, that's what he told me.

Yea, that's what I heard, my buddy freddy drove the car and said it was fun. I missed it by about an hour, would of liked to see it. How does it fit in the engine bay. Also, had he fixed the problem w/ the shifter hitting the dash when shifting?

Felt pretty good actually. His wiring was a little messy, but I think he hadn't cleaned it up yet. Fit pretty well, I think.
Freddy... did he like race Max (formerly of PYR) for the quickest "Street allmotor Honda" like a few weekends ago in Gardena?
I think I know Freddy.... very familiar name.

Nah, his name is Freddy Hernandez (SP?) You've probally met him before, he's been around the industry for some time. He use to work at pit crew back at the day. He's been working for the Kao brothers for the past few years at a shop they use to have called Car Toys and now at their new shop GT Group. He's my mechanic.
I'm sure you guys have crossed paths, he knows charles and all the other heads "in" the industry pretty well.

I can't wait to drive a k20 powered old hatch. Once I do though I'll know i'll probally ditch our b20 project for a k20 project for our CRX
so I'm not sure if I really wanna drive one yet
