I'm really diggin' the non-VTEC stuff lately, and have been running a pretty much stock B20B since early this year. The engine came out of my buddy Sander's car, has been beat on mercilessly by both of us, and is still running fantastically. Yesterday I took the car down to Dave at SMS with the original intention of getting a 2.5" cat-back put together, but after he looked at what I had (Fujitsubo RM01A), he suggested instead removing the JDM ITR cat I had and the bottleneck on the exhaust and replacing it with a bigger 300-cell cat. We also threw on a longer resonator, as the car was pretty loud otherwise. It has now quieted down a bit, especially at higher RPMs. Huge for Dave, it was awesome hanging out with him and he does incredible work.

I didn't do a before dyno, as I wasn't super interested in power. However, afterwards he told me about ProMotions, down the street a bit from his shop. I went there and put down what I thought was a very nice 144whp and 130lb/ft. This is with a 6400 rev limiter as well (stock valvesprings are old and weak, I'm trying to be careful with it). That is the real baseline that I'm looking for, as next week I'm putting on a mildly ported P8R head with Crower 62403 cams and Buddy Club cam gears. That'll be tuned on the dyno as well, so we'll see how it goes. There is also a possibility I'll be replacing pistons with stock compression 85mm ones, but I have to pull the head to see how everything looks first, as all of this is on a bit of a budget.

Lastly, but certainly not least, HUGE for Sander and his mAd non-V-TaK tuning skills. He's tuned all of my stuff, including this setup, and I wouldn't trust my car with anyone else. The man does phenominal work, as I'm sure some of you know. Mixed Motorsports FTW!

I don't have pics or the jpeg of the dyno runs right now, but they'll be up hopefully within the next few days. Then next week (hopefully) the updates will be posted.

 

Non-VTEC nonsense can be fun
I look forward to seeing how well your motor does. Which Crower cams are you getting? (62403-2,62403-3, 62403-4) ? You should see some nice gains above 5,800

 

They have variations of 403s now? I thought it was 402, 403, 404, and 405?

 

My bad-I just looked at Crower's site-the 5th digit denotes the grind.
"62403-2 --Stage 2 - Street/Strip package.
Most popular "all motor" profile.
Requires #84162 kit. 1000 to 8000+ rpm (15-18 hp).
Dyno Results 264 / 264 221 / 220 422 / 411 "
Good luck.
Here is a graph I got putting the 403's in a stock B20B:

 

What other things do you have? Header, exhaust, tuning, etc.

Edit: If I'm reading that right too, the Crowers look like they significantly decrease torque everywhere

 

Bone stock B20B. Just cams and valve train. Tuned with Hondata S100. Below 5,500 the stock cams were a little better, at 7,000 the Crowers were 40 HP better. You could really feel the difference driving the car-it pulled really hard up top and wanted to keep going.

 

I had them in my B18B before, and they did feel significantly better, but I never dyno'd them. The P8R head is also one of the things I want to see, as far as how much of a difference it makes.

 

 

kudo's on the numbers man! nice to see that b20 is being put to great use!

 

check out the 2 links in my sig. might answer a few questions. btw your dyno is basically what i estimated my car would have put out on stock cams..

 

if you are interested in a different set of cams you should give briancrower cams a shot: http://www.briancrower.com/ the specs look a little different than crower cams and the dyno of the basic non-vtec setup they show is pretty impressive.

brian crower was originally in charge of the import stuff at crower but recently decided to split and start up his own line of cams and stuff. he no longer works for crower.

 

JCushing, I've been watching your builds, that's part of what inspired the whole sticking to non-VTEC business.

As for different cams, I'm gonna stick with these for now. I got a killer deal on them, and I'm not desperate for more power at this point, but thanks for the heads up!

 

Update: P8R head milled 0.020" and Crower 62403 cams with Buddy Club cam gears (intake and exhaust advanced 1*), along with a retune. End result: 157whp and 125lb/ft on a Mustang dyno, same one that P1 has down South. Dyno sheet printed out like ****, but the power curves are smooth as butter. The torque curve is especially nice



I also don't have access to a scanner right now, so that's the best I can do with the sheet I have (which is one of the earlier pulls anyway). Just for reference, again, this is on a Mustang dyno. The previous pulls last week were done on a Dynojet. There's still 13whp increase, but that doesn't really say how much it actually increased, as the Mustang reads 10-15hp less than a dynojet. Whatever the case, I'm very pleased with everything, and once again, HUGE to my D-O-G Sander and his fantastic tuning skills.

 

very nice ! i'm awaitin a tune on my b20z motor w/ minor bolt-on's. where is ur tuner located ?

 

On the other side of the country from you, unfortunately

 

Go to EUGENE @ PRO-STREET IMPORT, its around the corner from you.

 

Here's the graph pre P8R.

 

Adams torque curve really flattened out after the cams and head, some what odd flat actually. Power even with the 403s kept climbing after 7200. We decided to stop because of the inherent weakness of the rod bolt.

-s

Ill try to see if i can find a good print out of the mustang dyno sheet.

 

looks good, id say your puttin out numbers similar to my old build with 404 cams and a p75 head so id say that p8r head is workin for ya... obviously if you really want to know before and after go back to the old dynoshop..

 

Thanks Dave!

And yeah, I considered going back to that shop for kicks, which I may or may not do. Only issue is that it's like a 2-hour drive for me. I wouldn't have done it there had I not already been at Dave's shop (though only because of the location, the guys were top notch ).

 

Non-vtec looks pretty nice, cant wait to start my build.. That is with 403s and the upgraded valvetrain correct?

 

Correct, Crower 403s, valvesprings, and retainers.

 

Thats awesome man congrats!

 

its these kind of posts and results that makes me want to swap in a stock b20 right now.
nice numbers
