The stock CRV head has identical ports and valves to the K20A/K20A2 heads. But it doesn't have reliefs for Lost Motion Assembly's. So I ran an OEM VTEC Killer setup similar to aznasinine(above).

Thats incorrect. B20 heads are identical (other then some small cam specs) to LS heads unless you are specifically talking about the P8R which is rare.

I believe he was referring to the K-series CRV, not the B-series CRV.

Stock Internals

InlinePro t3 manifold
Garrett 57 trim .63a/r
2.5 inch charge pipes

tuned on NepTune RTP by John Kerr at Innovative Motorworks in Carlisle PA

~312whp/272wtq @14psi
~266whp/225wtq @10.5psi (wastegate pressure)

Solid is 14psi (boost fluctuated a good bit) dashed line is off the wastegate.

Saw this thread linked to by @Reptil3 , thought it was a good idea to move into into the Performance forum so people could post their setup and dynos in here for some of the newer builds here on the site !


I'll add mine to get this topic (re)-started

99 Integra GSR B18C1
- CP forged pistons
- shot peened rods
- Balanced and blueprinted block
- Stock valve train with dual springs added on exhaust side
- ITR camshafts
- Jackson Racing supercharger running @ 10 lbs boost (CRV crank pulley + smaller pulley on JRSC)
- SMSP header, magnaflow exhaust
- Devils Own methanol injection kit
- Tuned on eCTune by John at

Maybe could be a bit higher #'s wise, but I'm happy with my build as power delivery is smooth and predictable, making it great on road courses....

Maybe @drmix can add to this topic too with his awesome and well thought out build

so i actually dont have any of these in my car currently, but im already logged onto photobucket so i might as well post.

jdm itr front on an eg hatch.
vitaras and eagles in a z6. stock head, 2.5" exhaust, lovefab ramhorn and a 15t from a saab viggen. this was on 9 psi. had it up to 14 but the internal gate wasnt holding till redline. it made 240 ftlbs on that 14 psi, ran 13.8'[email protected] on radials on like 16-18 psi boost.

started life as an automatic. i ripped it apart, welded in the cage, and put it all back together from the ground up

a bit older engine bay pic

84.5x89mm gsr block with b16 head. victor x, ctr cams, cp's and eagles right at 10:1. its a benson sleeved block. peakboost ramhorn, t3/t4 60-1, 3" turboback, comp st5 clutch yada yada yada. i still have this motor, its apart getting a new hone, rings, retainers and bearings. this is 16 psi boost using c12. i tuned it up to 16 psi on 93 pump, made 438/286. went consistent [email protected] with a 1.75 60ft. could go 10's, just need maybe 2-4 more psi and some seat time. track days stretch my funds pretty thin so i dont go often.

this was a straight b20, rs machines itr reps and brian crower stage 2's. overall it was sort of a disappointment. i made a few mistakes setting up the motor and it didnt really jive well together. it had a 2" axleback. mistake #1 . also i used a jdm itr 4-1 not the best design for a nonvtec, mistake #2 . it was mated up to an ls transmission, mistake #3 . i sold the head to a friend he put it on a boosted stock block ls. that car is still around 4 years later i just went low 13s on street tires and low teens worth of boost.
i still have the pistons and rods, im probably going to try it again with a css b20 block. i have some crower 403's lying around too.

Dyno sheet: I didn't ask for one. I was show the computer screen and that was good enough. I am posting this because I still feel it can be educational to some.

Engine bay: Stock everything, 2000 GS-R, other than cold air intake, Apexi WS2 exhaust, DC Sports 4-2-1 header.

Suspension: Unknown; it's an used, salvaged title, that has been lowered (I have not asked my mechanic with what coilovers/shocks).

1st dyno run with OBD2: 130 whp
2nd run with OBD1 and sHondata: 140 whp

My tuner changed the max rpm to 8400 from 8100 and the v-tec to 5000.

He said I'll need to take out the cat (is this smog legal in California - I don't think so), and install a Skunk2 intake manifold.

You probably won't be able to pass inspection w/o a cat in CA
You're right.
Mechanic just told me "not legal" a few minutes ago...
My tuner says "you are getting choked from the cat", but I think it's because he used to working on strictly track and drag cars that ride in trailers when they are on the street.
My daily beater has laws to follow...

It's very depressing to see that especially for very mild basically bolt on set-ups the stock GSR motor is barely making it above 170 whp.

AFter so much money invested to even have only put up those kind of numbers... very depressing...

Such as my numbers.

94-95 Integra GSR
around 140k Miles
Skunk2 IM
DC Ceramic headers
Denso Iridiums
Straight pipe to a no name straight through exhuast
I believe it has a "chip" in there, thats what I was told from the seller from when I bought it. I never got around to investigating it.
Exedy Clutch
Findaza flywheel, I can't remember what weight, I believe around 12 lbs or there of.

In my hay days of "racing"... it beat alot of cars I didn't expect it to, even a turbocharged sohc civic on a 40 roll(but then agian, it's a sohc right?)

In any case when I finally was able to throw it up on the dyno this was the results.

Don't mind the clear signals, they came on the car when I purchased it and this was 6-7 years ago.

148whp max? Wow... With drive train loss that's barely the stock 170 hp! I was shocked and hopeless.

I think for us NA guys who are going with the mild bolt on are better off buying a b18c5 and just dropping it in and calling it a day.

Why don't you find out? The ECU is very important, not knowing is just ignorance at best... if it's "chipped", who says it's done properly? That is very likely your culprit for what you feel are low numbers, as that intake could probably use some tuning to make it perform it's best
