From what i've searched the b16 flows better" but gsr gives a small compression bump.

I just want to know what kind of power i would make with a gsr head on my 99 si block.

Also, its coming with the gsr intake manifold so i guess i got to just take out the butterflies and all good?

 

same as your stock b16

 

Both heads flow nearly identical, it's been established numerous times. The GSR head would have some advantages on the b16a head in a slight bump in compression, "better" port entry angle, quench pads in the combustion chamber so more tolerance against detonation and running more timing. Disadvantages are having to use a different intake manifold. Using the GSR intake would probably work well but you'd need to keep the butterflies and keep them operational to get the full benefit. You would need a tuning system that can tune for the fuel and timing needs of the b16a and the butterflies of the IM.

 

Got ya so just stealin the valvetrain then!

Ok well my new question is, when using C1 cams, springs, retainers does the intake (dual) valve springs clear b16 valve seals?

The cams came with adj. cam gears should i use em or sell em. I know there are gains available but without degreeing<-- i wont know what to set them too -any info out there?

From what i understand you just drop em in do a valve adjustment and good to go. Thanks for the input guys im killin two birds here replacing timing belt and valve seals all at once! Tryin to build my little destroker to hang with my buddys h22a. lol

 

To the best of my knowledge, the C1 springs should be the exact same specs if not the same part numbers as the b16a valvetrain. There's no point in swapping them unless they are far newer or better quality. Clearance should be the same.

Keep the adjustable cam gears unless you're running stock cams and don't intend on upgrading the cams. In most cases you don't need to degree in your cams, just check clearances (P2V and V2V) mainly if you're running a fairly big cam. If you're running stock cams, just use 0-0 until you get it to the dyno and tune them.

 

C1 has dual springs i though thats why its recommended to swap over whole valvetrain? Maybe the C5 is better ....theres some threads on it to lazy to find out. Trying to go for a poor mans almost 180hp outta a b16.



No dyno for me ever lol rpm climb compared to time= gains
(only problem is recreating the same pull after changes)

Plus i guess it turns out the newest g-tech is ungodly accurate at calculating hp.

 

From what ive seen on dyno threads

b16a2

-skunk2 IM
-gsr cams-what ever springs and crap let you get to 10k redline
-decent intake-whale *****/Aem CAI/velocity stake on a Piece o pipe
-TUNE-chrome/neptune/hondata

=right at bout 176hp on the ole dyno jet

 

^

almost forgot header probly most important part as far as ive seen hytech replicas are BANGIN DC sports do ok i guess both followed by 2.5 out the back

 

why do you want to turn to 10k ????

 

hope to answer the most of your questions if im not to late. i am running b16a2 with 95 gsr head with 98 gsr cams. yes keep your cam gears. when timing this setup. your exhaust cam you can set perfect. your intake cam cause of the difference in the head size will either be a half tooth retarded or advance. impossible to get perfect. and the gsr head is a bit taller then the pr3 castings. i tried both ways trying to get it perfect it was either to high or to low. putting gsr head on b16 is like b16 on ls. never perfect. so how mine is set right now. i have my intake cam advanced and i retarded the cam gear to were it was perfect with timing light. on my cam gears its retarded 5 marks. timing light read perfect. so what your timing lines on your cams should look like is exhaust 9 and 3 o'clock like it should. and your intake. 8 and 2 then retard cam gear. as far as your butterflies. leave the plate. but unscrew them suckers out of there. i could tell a difference on top end. ifyou take the whole plate out. you will have problems with your FIT valve fitting. i learned the hard way on that one. as far as how my car runs. i pull on gsr tegs by 2 to 3 car lengths, i have a video on you tube at poormanctr. its of my 20mph to 80. and i have pics at myspace.com/doamafia. also on clubeg6.com. on the video. my timing wasnt right yet. just advanced with the cam gears at 0 degrees. i will post one soon of it running now.


using gsr ecu and tranny. i also have my head shaved .020
and gsr cams only pull to 7800rpm dont need to turn 10k theres no power there

 

so i can run gsr cams with not cam gears?

Im putting motor back together now dont have cash for gears as of yet.....

Im afraid to run the ones i got with cams they look like aem but 4 bolts no brand stamp..... black and silver???

WOW i forgot timing goes off intake cam that make it easy to degree in just wouldnt know vtov and vtop clearance. Im lappin in my valves RIGHT NOW!!!

 

Why 10k......... b16a2 at least dyno wise makes power to like 11k so revin higher makes sense on a budget with only bolt ons and gsr cams+valvetrain

Plus everone else is revin that high to make it to 170hp roughly so i guess its a must ...maybe im lost on that.

 

What dyno did you ever see a b16a still making power to 11k?? lol

 

yea you are super lost on that with gsr cams i wouldn rev any higher then 8500 and those cams will probly max out at 8000-7800

 

WOW go check out the all motor b16 section and spread the word. LOL

EVERYONE ive seen revs em out to right around 10k i guess you guys are the only ones that know your $hit


Anyways....

Is anyone out there runnin CTR pistons in a b16a2? Just tryin to find out because it seems very worth while i think its like around 11:1 comp. sounds like lsvtec with p30's but better. Ive heard that its a great set up yeayea but DYNO charts?

Maybe also a recommended build list arp rod studs? maybe smart or maybe not nec. Anyways lets keep the HYBRID Cheap build goin!!!!!!! SETUPS for the baby stroke!

 

Dont get me wrong i know power isnt made by reving higher or some crap.
Just followin dyno build charts seein what works and how to do it the cheapest.
If i had $ it be another rb20det build! maybe 25 if i had real deep pockets but hondas are cheap and if you blow em up ......OWELL
