love the series of head porting ,like the approach of less is more and where to cut and sand is very interesting to know where the power is hidden. keep em coming sir 🤓💪
Oh thank you man!!!
I agree its why im trying to share stuff thats often not seen when the port is "finished" this helps alot visually :)
but in reality too... at the most we are sharing 12-14% of what we do, I just prioritize sharing the "proper" steps and ofcourse the 86-88% power secrets are kept within :) so it may seem we sharing alot but its mostly basic proper approach only :)
excellent video and i like the jollibee cup in there
Hahahaha jollibee FTW!!
Oh man great video I usually sit there taking all the metal I can't take off but I just learn just round the off man u making think so easy thank u once Again for all this knowledge u passing thru old g lol
Oh man! Thank you I think the main thing is a lot tend to explain using “expensive” words to sound like an expert when if it’s simple then il explain simple no prob! :)
Kahit busy super busy sa work. i can't skip this class 😂. Present chief. 🙋♂️
oh maaaan thank you :) but when ur busy its always okay to check it "later on" as it might some info that can help as we always add some extra within the length of the videos
Gugafoods, is that you? Haha
Jokes aside, thats some seriously good porting!!
🤣 don’t know gugafoods loool but thanks man
Great information again! I can't believe how noticeable the swirl ports are on the P2J.
I Know Right?! even morw noticeable once ported but it does improve alot too so its decent
Yes, I guess it will still flow much better than non-vtec heads. I also noticed the right valve port was cleaner than the left valve port on each cylinder.
@@RisingBoostYT yes sir good eye...for some reason thats often trendy on the p2j it must be due to "wet flow" when its running and has fuel all over it that the specific side gets cleaner
Good call on using a stock ECU for the test :) would love to see the difference in AFR on the dyno sheet nung before and after for science
Yeah! i mean granted/hopefully if it improves 5-7whp? then it also means if he goes obd1 ecu + tuning on the dyno it might be even another 5whp so a total of 10-12whp overall
Oh yes!! thats the thing i will have definitelt includes on the dynosheet the a/f graph this way even the before and after a/f can be seen and even on just that alone we may have a more directional estimate after the second baserun :)
see? with guys like us we get more excited that the "owners" lol!!!
We can see just looking at the finish head that it Will perform very good. 👍
Here the VTI has the b16a2 engine.
oh nice here the b16a2 4door ek is the siR so the SiR here is the Vti there that is interesting to know
@@SRDmotorsports The VTI that was the b16a2 with 160 HP. The sir usualy have the b16 with 170 HP.
@@picole321 oh wow lucky portuguese people got two civic models with B series here all we got was one the SiR that is 99-00 year only so its always expensive here 🤣
Were we ONLY have the VTI from 1996 to 2000. The sir I was thinking it was only available on the japoneses market.
@@picole321 ah well our siR has the same usdm size cam so not jdm i know the jdm eg-ek years b16 has a slightly slightly bigger cam but not as big as CTR
Thanks for sharing this. For example, I would like to know how many km has this head? Do heads used in your videos have a lot of km? WD40 rules there again.🙂 This is a great step by step video. You included also pics of the water pump.
yeah alot of times over 90,000km cars like 150k-200k
@@SRDmotorsports Aha, but at this kms Hondas are more alive than ever. 👍
@@RRRRefuelRideRace yeah that is true thats why they always race haha
@@SRDmotorsports Agree budd. 🙂
@@RRRRefuelRideRace yuup
Great video, one question, i´m not a mechanic expert but i like to buy and do that to a D16Y9 head, it´s necessary to enlarge the ports or with a simple polish can be a good start? Isn´t for a race car, it´s to improbe power and fuel efficiency only.
Yeah that should be fine… I don’t enlarge the ports much really btw
Hi, im about to do this, my only question is what is the hole in the last exhaust port?
Egr recirculator etc etc nothing we can do about it or something
@@SRDmotorsports Can i run high comp pistons without a cam safely? Im rebuilding it and dont have the money for the cam, how could i run 11.5comp ratio without knocking?
well the question is why high comp pistons?
A lot of times and most builders would prefer cam first and mild comp…
But sadly locally it’s always pistons first and nobody would admit to cracked piston , bore or ring lands and I see that often locally (Philippines)
check out the volumetric efficiency video to gain a wider perception
Where are your shop located sir? Might visit sometime 🙂
Antipolo, near sumulong
Lets say we do the troll the other way around, p2j cam on a p08 bare head? Would the p2j cam match the airflow of the p08 head?
it’s not about just matching it… the “other” video I explained that locally peeps do this for the supposed “compression” gain on the so called “square” chamber which I showed the calculation to be too little of a gain for a lot more erroneous results…
that’s ASIDE from the cam being incorrectly “keyed” (sa kunya) I explained on that video that sure u can compensate with the camgear BUT the other sensors on the dizzy like what or when it triggers the injectors? Will be out of sync…
if a camgear is the solution? Why did crower come with a 63442Z (for p08) and 63442Y (for d16y8) if ever camgear lng need adjust?
so reversing it? The airflow is the last of ur worry it’s still the incorrect cam timing with the lobe and injector phasing
Ooohhh okay! Well, as you have said before 17.X on a quartermile (with p08 internals on p2j head) so its either you go straight (p08) or go home 😂😂😂
yep and a straight VTi of someone I know on STOCK vti tranny already did 15.1sec in Clark
at the same time a VTi with p08 internals and even on a skunk2 cam? Ran 15.6sec
that’s done by a well preached PADEK builder 🤣 no posts but next thing u know they selling the parts 🤣
Curious too know what kinda power increase did this head make ?
We haven’t dynoed it but it did run 15.1sec on a 4door with lame traction lol
Hey man, I’m currently routing coolant lines for my Y8 and I was wondering if the water pipe would be a sufficient coolant feed source. Not sure it would supply enough coolant until the thermostat opens.
you mean coolant feed source for the turbo? if so, yes it is sufficient
@@SRDmotorsports yes, that’s good to hear haha thanks
@@tayvonrose2528 thats where we actually route it from... then aft turbine is joined at the bottom just like its oil system it relies on gravity
so it wont work if ur oilpan is above the valvecover hahaha
@@SRDmotorsports I have my coolant feed on the water pipe and my coolant drain on the rads bottom end tank. I Think I should be good
@@tayvonrose2528 sounds good indeed
I have a civic lxi...can I slap p2j head or p08 head and just lock the vtec??? do I still need to buy a vtec dizzy, programmable box and alternator???
yes the dizzy has to match the head, so it has to be rewired and locking vtec wont make the lxi program match on the new head (alternator is okay)
with that approach it would be better and yield more performance of you just have your lxi head ported, thats the story of this p2j the complications of going p08 head vs just porting the current and owner was quite happy
@@SRDmotorsports so you advise me to just port the heads instead of going p08??? Do i still need to get a programmble ECU for tuning??? Also what headers do you advise for this setup??? Your channel is really informative to us DIYers!!! More power!!!
@@WorkingClassMedia ofcourse with a tunable ecu the upgrade gains will be more or exagerated = we all want that lol the reason for my suggestion is cuz unlike swapping a different head u automatically need a dizzy and tunable ecu sure thats a given but the total cost becomes huge...
ported head of the same ecu/car should be decent and it wont be a must or rushed to need an ecu but once u rechipped? you can expect even more gains...
headers, the usual 4-2-1 Ninja usually works real good
@@SRDmotorsports thank you sir…a p08 head swap is going to cost me an arm and a leg right??? lol…..so head works it is, then save up for a programmable ECU..i already have a P08 intake manifold installed by the way lol
@@WorkingClassMedia oh nice then now it breathes alot better than a stock lxi manifold good job!
Hi sir, please enlighten me, planning to change the internals of my vti to a p2j 20cam lobes, whats the benefits of doing it? Thank you
If it’s a p08 cam 20camlobes internals??
Pls watch my earlier vid on the p2j mod they do and on how wrong it is
@@SRDmotorsports thank you for your quick response, I don't think its a p08 or i maybe wrong, they said that it will be a bolt on conversion, from a stock vti internals to p2j 20cam lobes
@@4773N. yes it is bolt on but wrong
Watch that vid as I don’t think I can put link on my comment it’s
“p2j vti head p08 cam tech info” the title and you will see how wrong it is and u will be victimized by spending labor and or they are selling it to u so they can go back to stock
I know a place in Antipolo that did a lot of these then now are trying to go back to stock p2j cam after the video I made which was for more awareness
Because if it’s a USDM head then why say “internals” 😂
@@SRDmotorsports thank you sir, will be watching the video now.🙂
Anyway, how can i gain more from my stock head and cams without sacrificing fuel economy? I feel like my vti is running quite sluggish, a shop already checked my engine and said that my cam timing is off by half a tooth.
