D16y8 P2j VTi Head Porting and Development

[@SRDmotorsports]

Just realized the end screen is the episode 1 of the VTi series il edit in a few days but here is the playlist with over 90 tech videos kzbin.info/aero/PLSfTkjTlf41GKs4tX6A_oSSZj6Ei88mIB&si=kG6o9OjqgOLPywBL

Great work that thing look amazing

[@SRDmotorsports]

ended up being a fun stocker indeed 😎

[@StraightOutThaGudda4U]

Amazing porting work and explanations as always brother, i know you made the valve job vid which i am gonna check out next because i was just about to ask you to do a vid on that topic😅 great vid as always brother

[@SRDmotorsports]

@@StraightOutThaGudda4U nice that’s good timing u were gonna check the the valve job stuff

[@StraightOutThaGudda4U]

@SRDmotorsports yesir

[@SRDmotorsports]

can’t wait for your next projects in the future as we usually hit it up in the dm’s and figure out good stuff 🔥

[@Rodman8500]

Would be nice to see a video explaining valve jobs and what they can do to make it more efficient and how they can affect if not done taking in consideration the new mods been done to the head. nice porting by the way!

[@SRDmotorsports]

@@Rodman8500 hey watsup Rodman! always remember the name of my fav rebounder off all time 😎 have noticed you been active since the early days of the channel I really appreciate that 🔥 and excellent idea on the video! will try to work on that and I will try to make a very layman’s kinda video and hopefully some good visuals and imagery to share the info well enough! thanks for that idea man

[@Rodman8500]

@@SRDmotorsports Always lurking and learning and yeah one of my favorite players too that is why i have the name because he and i share the same of name and thanks for remember me :)

@@Rodman8500 that’s def cool to know man 😎

[@Jamraliya]

Wow! Nice sharing, have a nice day

[@SRDmotorsports]

thank you thank you 🙏

Porting is meditation 😁

[@SRDmotorsports]

it is actually… for me 😎

[@Carbonarars]

@@SRDmotorsports 4 me 2.

[@SRDmotorsports]

maybe one day il buy a digital clock and put it by the porting bench wall… Sometimes its 1:20am 😂

@@SRDmotorsports time is relative. When you do,what you love, time goes by fast. When you do things you dont Like, time never ends

so so true actually + late night =‘more peaceful and quiet… the grinder is free to shine on its stage 😂

[@bryanlarrea2867]

these porting videos you got are good! have you done much port work with the p2f d16y7 head?

[@SRDmotorsports]

@@bryanlarrea2867 I believe locally that’s a civic Lxi engine to us, unfortunately I havnt had a chance to work on one… BUT if I do find a cheaper good priced core? I might actually get it and study / port it and make a video here for you guys

[@markvillanera6384]

are these port n polish applicable on by just using stock camshaft (20camlobes)? or do i need to upgrade also to aftermarket camshaft? really love watching ur vids thank you for your response in advance!! ❤

[@SRDmotorsports]

@@markvillanera6384 yeah when done right it helps even on stock cam This is the head on the vti rebuild series we did the stock one

[@AwesomeBoss55]

would it make sense to put some extra material onto the port divider and smooth it out so it's not as far into the port? i feel like that's one issue of these but the combustion chamber looks better than Z6 imo

[@SRDmotorsports]

possible but it’s also canted to the left, focusing on swirl in the chamber

[@AwesomeBoss55]

@@SRDmotorsports yeah fair. It makes sense for low/high rpm but I‘m guessing it‘s hard to keep velocity and flow up with a swirl design and it‘s very sensitive to port changes but it should be able to make more power at the same cfm

[@SRDmotorsports]

Yup true

[@hondagamer79]

Or do battle of dyno or race or something with your engine you build

[@SRDmotorsports]

yep we havnt been racing recently due to commitments, last race we did was actually Jasper’s EF on b20vtec way back before the channel

[@hondagamer79]

@@SRDmotorsports nice

[@SRDmotorsports]

yup

[@fazesalv8707]

do you use a flow bench?

[@SRDmotorsports]

yes but not all the time that’s why I don’t talk about it, we don’t sell cfm here

[@hondagamer79]

How about you do challenge get car for project and build engine and body if you want or keep it sleeper and film you driving it and dyno it race it … its will be cool videos to make and you having fun and new different things you will film

[@SRDmotorsports]

that’s actually been a thought already…just checking for chances on such sequence but definitely it has been thought about

[@hondagamer79]

@@SRDmotorsports :)

[@SRDmotorsports]

gonna be fun

[@huwaki]

Newbie question, would that lean out on stock tune? since technically there will be more airflow.

[@SRDmotorsports]

@@huwaki good question actually… and technically it does and could? But just like installing headers changes the air fuel mixture But we see a ton of guys change headers and stay on stock ecu for all their reasons? basically you get maybe 60-70% of its capabilities by just bolting it on but with ecu tuning it can guarantee you get 100% of what the head can give or header or even intake

[@huwaki]

@@SRDmotorsports I remember putting P2j Intake on my non vtec caused engine pinging, I suspected it was leaning out on fuel hence requiring higher octane. So to summarize, yes it will benefit on how the stock ecu can compensate on AFR but can be fully unlock it's potential when tuned? Will we be seeing a tune onto the next video? :D Cheers for a great informative video. Hoping to visit your shop soon!

[@SRDmotorsports]

@@huwaki the owner of this head is the 1996 VTi series we did actually yeah the owner has future plans on switching ecu and “other” things so most likely as soon as he finds time, but I think he is also looking to a quick repaint just to restore the white color as it has some slight damages in places but most def if when he goes for a tunable ecu we definitely will make a follow up video to his series

[@washhalhafeez1824]

"Does a ported and polished head increase both horsepower and torque, or is it solely responsible for horsepower?"

[@washhalhafeez1824]

Hope to see a 3-5 WHP bump from this rebuilt head.

[@SRDmotorsports]

@@washhalhafeez1824 hp is a product of torque over time/rpm Ofcourse torque can only be made as much as what the displacement has example no way a 1.6L can make the same torque as a 2.0L unless turbocharged

[@washhalhafeez1824]

@@SRDmotorsports alright and as far as this d16 head is concerned ofc we are expecting more torque and hp out of it now compared to the previous scenario of it,right.

[@SRDmotorsports]

yes
