I initially built a ls/v that ended up making 201/137 but like everyone, always wanted a little more. I ended up changing up the bottom end. Here's what the motor consists of:

B16 head with PNP and slightly milled for flat surface
skunk2 pro springs and retainers
skunk2 pro 1's degreed in
440 injectors
Skunk2 pro intake mani
skunk2 68mm tb
sri with velocity stack and filter

84.5mm sleeved bottom end slightly decked for flat surface
Rs machine pistons
stock ls rods with arp rod bolts
acl standard bearings

hytech rep header
2.5" cutout after header

Car made 215/163 tuned on eCtune. This was on a very hot day. The more we let the motor cool, the more it slightly made. Im pretty sure it is capable of 220. I was thinking of changing the cams out to pro 2's to get a little more.

Let me know what you guys think.

 

pro2's and a 3 inch exhaust.

 

What was the bottom when you made 201/137?

Yes Pro2's would get you to 220, maybe even a bit more.
You may also want to think about an intake change, Performer X.

 

This is also my daily driver. Are the pro 2's ok on a daily? Also, I did not want to drive around with a loud exhaust, which is why i have the cutout setup. Im running a greddy sp2 daily and when i race, i open the 2.5" cutout. Makes a big difference in the power. Gave an improvement of 14whp and 10wtq on the old lsv setup.

 

The old bottom end was pretty much the same thing, just a 1.8. Rs pistons, stock rods with arp rod bolts.

I also thought about changing the IM. I know the performer x would put the power up top but didnt know if it would really make a big difference. I forgot to mention that i did portmatch the skunk IM to the tb.

 

14whp and 10wtq nice gains with the cut out

 

damn that is a good gain for that cut out...i have a ?...if i have a full exhaust with test pipe would a cut out make any gains since i have no restriction?

 

Definately Pro2's.

I don't see how they can't be good for daily driving, they make much more power on the low cam, making 'daily' driving more enjoyable.

I've built and tuned a number of Pro-series cam'd motors to date. They all start, idle, warmup and drive exceptionally well. Your tuner will need to be patient with the idle settings and advanced tables for Pro-series cams.

EDIT - Just saw you have pro1's, did you tuner get them to idle and drive well? If so, Pro2's aren't that much more aggressive on the low cam.

 

It all depends on what kind of exhaust it is. The cutout basically is a testpipe but with a little dump on the size. When the cutout is closed, its a regular full exhaust with a testpipe and its still fun to drive but i definitely can feel the difference with the cutout open. I assume you also would get gains from a cutout, i dunno if they would be as good gains as i got but there should be some gain. Im still hesitant on the 3" exhaust thing. I feel the gains wouldnt be that much of a difference because i have a full 3" exhaust or a direct 2.5" dump.

 

I used to have a big issue with my idle when i used to run crome but since i switched to ectune, the car idles perfect at 1k and it runs great. Vtec transition is super smooth like its suppose to be. How will the pro 2's change this? Are the high lobes a lot more aggresive than the pro 1's?

 

Yes, the biggest difference will be on the high cam. The low cam is just slightly larger.

You should be able to set target idle in eCtune to 850 or 875 RPM. Keep the fueling just south of stoich, and make sure your moving idle and idle vs ECT are all in-line with your target idle value.

 

does the new setup feel a lot stronger than the old setup ?

 

well i have crower stage 3's in my h23 with high comp. so it not like im all stock i would think i would atleast get wat kinda gains u did then again i gota get a good tune lol only running a base tune for now

 

Yes it does, just a lot more wheel spin now. It took me from 137wtq to 163 which is a big increase for our cars. I'd just like to see my whp a little higher.

 

So i just picked up some pro 2's, hopefully they will do me good.

 

very similar to ur build, my bro has one. pro2 cams making 240whp tuned at church automotive

 

Nice. Im not expecting 240 but initially my goal was 230 so that would be nice.

 

would love to see what you pulled out with the pro 2's. im putting together a b20v right now 85mm sleeved. some people told me to try boost but for my daily i dont want that hassle. my set up with be
b20b block
85mm bore darton or RS machine sleeved
micro-polished and balanced crank
eagle rods and arp rod bolts
cp 85mm 11.5:1 or 12:1 compression pistons maybe 12.5:1 but dont want to push it since ill be on pump gas 93 octane
golden eagle vtec conversion kit with a cometic 85mm head gasket
acl bearings
gsr or itr girdle

head will consist of
b16a head
very mild street port and polish
supertech valvetrain with flat valves
skunk2 pro 2's
victor x manifold with 68mm or 70mm tb port matched
and either hytech tri-y replica header or rmf narrow style header.

i will be keeping a/c in the car so that may cause me to lose a few horses. not too many i hope. motor will be going into my daily driven ek, its my work car.

 

You should pull nice numbers. I have a/c in my car now also but it never stays working. Im close to just removing all of it. When i was at the dyno with the old ls/v setup, the ps and a/c belts flew off and i pulled 4whp more, lol. The a/c wasnt on so it was probably mostly from the ps system. Since that day, i have never put the belt back on, and i even removed the entire system.

 

power steering i may do without but a/c im definately trying my very hardest to retain.

 

I just installed the pro2's. The quick settings provided by skunk did not work and was causing a clearance issue, so I used the same cam settings as I had on the pro1s. The pro 1s were degreed in and believe it or not they were set to +5 in, +4 ex. I put it to this setting and it runs fine now, no clearance issues, I just find that camgear setting very weird.

 

Power is now good. nice. TQ is big.
Dont F-around this is a nice set up.
Bigger is not always bether !
you gonna gain 10Whp. spend 1500$ and Over ( exhaust, intake, )

If you really want more
Go for another bloc B20 85mm bore X 95
get a stroker kit... if really want to stay in B serie
180TQ 240Whp

 

would like to see the dyno graph

 

I will keep you guys updated. I want to get the new cams degreed in before going back to the dyno.

 

If you plan on tuning cam timing on the dyno, just use the quick settings for installation.

-1 to 0 range for the intake, and +3 to +4 range for the exhaust is safe and close to what will make best power for Pro2's.
