- Adobe retired its flash player no problem we got u
We analyse the close ratio 3rd gear and 4th gear in-relation to the engine powerband using our own dynosheet that lets you decide what works for you
a few pointers on engine planning with regards to power the graph shape on the dyno and many more ultimately to help newcomers avoid unnecessary expenses on their projects. As I have seen quite a few that spend on close ratio gets then need more and more and more until they decide to stop spending extra because they are not getting any faster
Mfactory and other gear manufacturers have given us the great benefit of choice but lets be wise our example is of a D16 sohc and because Adobe Flashplayer no longer exists we try to help our way
another offering by
SRDmotorsports
we hope you enjoy

Two days after this video, i see local FB posts seems to agitate the "papeymus" ones lol
still glad it means its generating traffic and traction for the video :)
keep safe everyone!
sino kaya yun??? 😂😂😂😂😂
@@mikestorationtv2295 🤣😂🤣😂
Absolutely would do this modification to transmission can easily make a stock power motor feel surprisingly fast.
Definitely agree man so true!
This one goes also in the field of motorcycles. Nice showing of what means what and how it works. Thanks for sharing bro, keep up the good work just like you always do.
yes definitely agree same on motorcycles like in cars its final drive in motorcycles its the gear sprocket thats easily changeable
@@SRDmotorsports Agree my friend. :)
@@RRRRefuelRideRace yes sir
Thanks I really appreciate your videos man. It’s crazy what you guys do in the Philippines.
I’m in Chicago illinois. Big k series guy and trying to determine what ratios to go with next and thinking of maybe exploiting a 5 speed trans but making the ratios work. Seems like it’s best to have the next gear to drop into the flat torque area before torque drops off.
Love your videos man, your dropping a lot of videos that is super informative
Oh wow thank you chi-town brother!!
MAaan you said how you are taking the task on the K gears? Is perfect I mean it’s exactly relatable to how I explained it here… 5spd or 6spd K trans the rpm “pick up” point of the NEXT gear is where it’s at :)
To keep the gear changes “fluid” and keep constant push/acceleration good
I’m Filipino too man. My parents are from Davao. Do you have Instagram by any chance?
@@kpwr6197 yep I do but still not totally shop IG it’s 50% personal so some quotes and trees are there hahaha it’s @ralfsrdms
Another great content yesssirr!!! Thank you SRD, I was also curious about the S40 LSD tranny ratio any great advise on this for a sohc ph16 engine? Many thanks!
thaaaanks man!!!
well if the s40 is b000 ? then most likely it is vti geared which is the same as ph12 so thats a good one indeed
Worth noting here though we discussed it on the SRD page…
S20 is a designation for 92-95 / obd1 / 5th Gen
S40 is a designation for 96-00 / obd2a/b / Gen6
Both can have an LSD as it was a Honda optional accessory back then when u bought it bnew in Japan (the car) just like some B16a were rarely lsd
I share this cuz I saw a random fb post claiming that it’s s40 so it’s LSD?!? It’s not always :) worth noting cuz that random post was from a
“buy and sell” dude lol
Here's my support. hindi ako nahuli ngayon sa panonood. hehe 👍😊
heyyy! nakita ko ung mangos!!! 🤣 lately fav ko sour mango juice 🤣 green mango blender lng ftw!
thanks for checking this out :) improving my edits and i know it gives u ideas din kya win win situation!
Dropping gold nuggets here! Naalala ko gear tuning with gran turismo 1 haha hanep
hahahaha there was one car there i think it was the Amuse rx7 or supra? no matter what u did it was fastest khit you hit a wall...
naturally was my fav car
but u get it lng as reward near the end hahaha
Watched this twice...
Then downloaded it just to make sure i missed none 🤣
hahahaha now thats smart!!
Planning to change my FD to 4.7 with stock vti gearset.
yeah i would do the same, its a simpler move and the gear spread is still like oem so its nice
I had already realized that shorter cash ratios would not always be faster.
When I changed the tires from 195/55/15 to 195/50/15 the car was slower.
yes!!! thats my goal on this video to let each one figure out what wrks for their own car and driving style...
i believe you saw this because same rpm limit right? so for the same rpm shorter distance reached in total
@@SRDmotorsports Yes. the same rpm limit, only the tyres change..
@@picole321 that is interesting because your findings are correct even with math and the calculator :)
SRDMotorsportsTV can i ask feedback if installing a 12LBs Lightened Flywheel (competition clutch) to a stock S20 B000 ? good for daily driven and occasional sprints? no problems driving in incline/steep uphills? ty
Actually the problem on incline or steep uphill is a myth because power and torque is generated by the engine
The lighter flywheel changes the rpm rate of going up BUT also going down maybe that’s why they said it’s hard to drive but IMO just imagine it’s a motogp bike 😂
I’d always choose a lighter flywheel just the wallet never agreed 🙁
@@SRDmotorsports thank u for the quick reply, i saw a video with a lightened 12lbs flywheel the revs go up and down quick vs a stock 18lbs
@@salteveline yeah maybe if we heel-toe daily it would be tiring 🤣 but i think its fine
IMO theres a bigger change in driving habits from driving a stock clutch to a tri-puck
than it is from a stock flywheel vs light flywheel
@@SRDmotorsports I agree. I changed my K24 swapped Civic's flywheel from a stock 16lb RSX flywheel to a 10lb JDM DC5 Type R flywheel and the RPM definitely responds to throttle a bit quicker, but I haven't noticed any downsides. No problems with hills or hill starts even with several passengers and a lot of weight in the car and there's no increase in noise or vibrations.
@@averyalexander2303 yep the quicker up rev and down rev will be more driver preference but since I was always a motogp fan first… I’m okay with it 😅
eto hanap ko 😉😍😍😍
Yep
Does it need any modification for the stock 3rd gear to fit into 4th gear?
just invert it I believe if there’s some machining it’s the internal ledge of the gear into the shaft
hi SRDmotorsportsTV thank you so much for educating us re vti/lxi/ph12 tranny, i hav a d16zc s20 b000 tranny, which tranny gear upgrade is better:
A)
1st 3.250 stock
2nd 1.909 stock
3rd 1.565 MFactory 3rd
4th 1.125 stock 3rd to 4th
5th 0.702 stock
FD. 4.25 stock
B)
1st 3.250 stock
2nd 1.909 stock
3rd 1.125 stock
4th 0.909 stock
5th 0.702 stock
FD. 4.7 MFactory
B is better any day cuz the gear spacing is correct
For me it seems abnormal to have close 1-2-3-4 tapos use stock 5th so u can go to the highway ☺️
They’d say it helps? I disagree cuz the ones I see got stuck in the low 13s for years
And went to 12s by turning it into a “racecar” on special fuel 😂 so where there did the gearing help? Hmmm lol
mines like B = stock esi
I do plan on saving up for a 4.7fd so hopefully soon :)
What are ur taughts on my vti ph16a, planning to replace my stock transmission to S20 b000 short shift. Thank you,
Check my other video pertaining to that exact situation
I measured and counted a VTi ph16a transmission and compared it to an s20 BOOO “short daw” transmission
Here it is
czcams.com/video/m_R7cMLioQs/video.html
I hope you watch that video based on what u wrote its exactly why I made that video your vti gears are the same as an s20 and ph12 and esi so called “short”
So why waste money
@@SRDmotorsports finally i was enlighten. I was about to buy a ph12 tranny for balasa or s20/s40 trans for a upgrade on my 97 bigote sohc vti for racing purposes. Haha buti nalang i saw ur videos, same lang pala sila. Muntik na nabudol 😅😅
Anyway, What can you suggest for a better upgrade on my tranny. Mfactory 3rd gear?
By the way my vti has a b16tb and b16injectors, headers and box.
Thank you sir😊
I guess mas ok to get gears from MTM since he can outright make you a custom one for almost the same price as an MFactory? Granted you have a dyno sheet to base it out on hehe.
Still haven't tried my 20" tire sa BRC or CIS :( soon hopefully.. 1-2nd gear felt good though..
true on MTM gears but also there are limits like we both know "ratio" is divided onto both teeth gears? meaning... physically impossible to get 1.370 third gear sa sohc etc etc but yeah MTM gives us that freedom
Me il stick to my ph12 MAYBE one day MTM frst gear extension or MF since similar price naman
or heck final drive nlng done deal na hahaha
but then final drive is less importance when there is a 20" option na eh
@@SRDmotorsports Agreed, 20" tires are not ideal for cars that are too low BTW pero i love the fact that its an easily reversible "FD swap".
@@SRDmotorsports Would be a fun experiment to find a stock civic and run this compared to stockies, or ones with the common 195/55/15-195/50/15 haha.. Sana magkaroon ng drag testing day this year..
@@mikodelacruz yes on too low so "no to stance" kidding hahaha
it is a significantly smart choice i mean heck even M&H slicks have 20" 23" 24.5" and bigger
for me the reason id consider a 4.7fd ? is not cuz its better but its because for me to want that? means eventually the sohc will be strong enough to power down the line on 4.7 fd and 24.5" slicks 🤣 bisi style lol
or better yet since our 195/55/15 is 23.7"
id run a 23" MH slicks if i had a 4.7fd granted the sohc engine can take advantage of it IF it makes power? oh man... that would run good times lol
What if I wanted straight cut gears
Then it’s custom
If you run 1954515 vs 1955515. Without the expensive fd swap.
it helps a little... but 45 series 15s is quite hard to find and it will also be a balance of grip because the lower profile tires have stiffer side walls and stiffer sidewalls means it wont conform to the ground easily so less traction on take off
its why slicks have wrinkled sidewalls when we launch so it conforms to the ground maximum
Hi sir may i ask which is better to put an fd 4.7. s20transmission or stock esi tranny? Thank you sir in advance
Esi/s20 B000 transmission because even a Bseries 4.7 helps when u are hitting high rpm that the sohc doesn’t see
@@SRDmotorsports last question sir.
I have a sohc esi camgear box headers
Is it okay if i put an mfac3rd gear and 4.7 final drive or 4.9? Thankyou very much sir
@@carloflores2944 Mfactory 3rd gear only works with the inverted stock 3rd as ur 4th (u finish 4th gear parang tersera mo) and so adding a 4.7 fd this reminds me of an onboard vid in Clark a sohc bfor finish line let’s go of the throttle about 80ft away… some say “not sagad” but that’s cuz ubos na 4th (na dating 3rd kase) wala pa finish line
The Mfactory 3rd is good with inverted 3rd as 4th IF kasama Mfactory 5th Pra dikit dikit lahat
But why they don’t? Kase mahirap sa nlex 5th mo that close hehehe pangit sa long drive
So just a 4.7 on ur current esi gears is perfect na
@@SRDmotorsports thankyou po sa kaalaman thankyou appreciate it po.
@@carloflores2944 no worries man! nice you checking out “details” kesa “Sabi Sabi” hehe
Playing with a dragy brought me here 140whp ZC on full interior 23inch tires, only got 16.03s on a quartermile and been receiving alot of advise to change my 3rd gear (stock vti tranny) or the final drive, well, what can i expect? 😂😂😂
no need to change 3rd gear or final drive
What is ur current transmission? Looks like u have a Lxi a000 tranny?
what is your 60ft on the 16.03
Way too many slower than faster na nka 3rd gear or final drive one thing in common is they all spend a lot of money 😂
A friend of mine tuned a stock vti with proper vti tranny na B000
Last time in Motul but carbon door and hood
15.1sec stock vti engine and stock transmission
Malabo nasa 140 un vti lng un
Oh yeah you need to put alot of good money to hear those good sounding close gear😂😂😂
60ft - 2.45
0-100 - 8.4s
For the trap its 139@1/4 mile
Well, could it be with the powerband of the tune? My engine peaks at 6900rpm and 5200 for the torque, not really sure really hard to reach the 15s
@@elijahcarmona8487 a fast sohc with ph12/vti gears sound as good btw 😂 just like an SiR with stock tranny not all siR nka typer tranny to sound good or go fast 😂
@@elijahcarmona8487 looking at the 60ft
Looks like if u do a 2.2sec 0-60 ? Thats easy 15.7-15.8sec for u as is no 3rd gear lol!!!
oh man i really want that mfactory
but there is another option with 1.364 3rd gear and 1.040 4th gear from whoppee doo racing
but it’s probably best to finish off the engine first then build the transmission based on how the powerband is
i’m more of a hillclimb/marilaque type guy which is why i was leaning on mfactory
anyways december pa naman yung target for stage 3 cam, intake manifold, etc. so transmission would probably be next year’s puzzle
great video as always!
yep i mean last na ung transmission
heck Bisimoto ran 10.7sec on a zc gearset but 5.1 final drive

Can u build a carburetor all motor d series
locally for us thats a ph12? ofcourse yes i believe the carb specialist i know still has his shop open so in cases that the carb needs expert care i bring to him but most of the time we get to work it easy as i do and like VW beetles too and lotsa webers 🤣

Oooh thanks for checking this out man!
Sir can i ask if what is the code of the stock vti tranny?
I’m not sure our local has a code but
On the spot where u put the axle? The circumference of the housing has a code it should be
B000 to be a vti because LXi is A000
Cause last week we bought a p20 B000 tranny it came from a ph12 engine is it same with the vti tranny?
@@sharmainecastillo3446 ah yes p20 is ph12 the gears are the same just the internals such as “gear selector”
Ph12 is aluminum and vti is steel but not interchangeable
However the gear ratio = identical so atleast the vti u got has good gears
Do you have a facebook account?
@@sharmainecastillo3446 ah yes the shop page link is my fb page I’m the only one who manages it…
Here or there u can ask anything related to these stuff
Is the 11.800 car around 2070 lbs?
the grudge race rule was 900kg both were weighed bfor n after
but both were in the 940-950kg range so
2,068-2,090lbs
when i think about it now we ran 12.1 in 2017 on e85
these guys ran 11.8sec 2 months later 🤣 on e85 too!!
was that fast
@@SRDmotorsports Just realized the estimation using this calculation is quite close: hp = weight in lbs / (ET / 5.825) ^ 3
@@findtherightbeat actually good point! and now when i think about it? aint it funny? back then it was "wow" fast, til now its considered fast
but with math? its "tama lang" hahaha like man! we aint even doing our best yet and its that fast whoa
-crux to the perception
or in this case
-fuel to the fire lol
that was a 250whp vs 260whp race
both poppin 11.8s
today? we see lodi numbers 265-275whp
yet way more race fuel than basic e85
still reasonably in the 11s as only 2 ive seen now hit 10s but backhalfed pa chassis
