I got a 99 Civic SOHC D16Y7 NON-VTEC
Am running a Greddy TD04 15G Turbo
Its being tuned by Hondata 3b with p72 ECU
Being Tuned by Hondata. What is the safest Boost level can i do on Stock internals.
Am also changing out the intake manifold to a D16Y8 EX. Its being port-polish rite now. I was hoping I can do 10 psi dailiy driven.

d series stock internals are very weak. have heard the rods are good to 220flywheel. i have never broken a rod, but have broken the ring lands on 9psi and a bit smaller turbo than you have. i would say no higher than 7-8psi with good tuning

You can probably boost 10psi on stock internals. Just make sure you get a good tuner.

It's not the boost pressure you are making, it's the amount of power you are making that you need to worry about. 180whp on a D16 is safe with good tuning, 200whp is marginal (however stock injectors won't give enough fuel for 200whp).

You hit that right on the money! Ive been saying that on this forum for a long time finally someone esle can say it....

Johnyquest

Shoot for around 200whp and you'll be approaching it's limits. I consider 200 to the wheels relativly safe. I'm boosting 11lbs on a .48 t3. 15k miles so far, still giong strong. AFC "tuned" by me (right!), no prior experience. Just retard your timing!

Good luck.

Their ya go, exactly.

im at about 8psi d16y8 w/ greddy kit on stock internals since last year and im doing just fine.

hondata tuned. its been good to me no probs at all.

here in CA we are stuck with 91 octane so if you can feed your car 93+ from the pump you can probably handle a lil more boost with good tuning.

from my limited experience 8psi-10psi depending on the tune and gas u have available.

I have ran 9 dayily driver on a stock y7 for like 7 months now and have done 12 racing a swaped type r on the freeway, D series have *****

Cruiser G

I run 10psi on my y8 daily on the greddy kit with the hack. Shes been running like a champ for a good while now. I know its at its max, but Im building a z6 right now to swap it with the y8 so Im not too worried about it lasting forever.

myinvestedagony

also running 10psi on stock longblock JDM D15Bvtec AFC hack and a TDO5H/14b running some where around 200whp and mid to high 13's Honda tuning ran 14psi on a T25 up to 215hp on a hondata system so right there is a good mark to aim for I say 11-12psi with that turbo and hondata make some real HP with that Dseries you got the setup to handle it

what engine managment were u using? ive had friends running 10psi on a 12:1 FMU and inline. ran that way for 3 years then he got tired of it and sold it for an awd celica turbo.

if u run a SAFC, DSM 450 cc injectors, MSD BTM and get some tunning on a dyno 10psi is fine, with almost any turbo!! of course a big T3T4 sper 60 or bigger would make to much power and cause problems, but at under 11psi, your not going to make so much power youll blow your engine to peaces, i mean it would be hard to hit 250+ hp on a stock Dseries running 10psi, the turbo would be so big it would never hit 10psi.

im new to FI. whats an AFC hack??

horror

i dynoed at 221whp/194wtq @ 11 psi on my stock internal y8 w/ 15g-greddy kit and the hack, along with a couple other goodies like edelbrock im, 2.5" dp, etc.. this run was done after i street tuned without a wideband, i made some adjustments but was not able to get back on the dyno since then to see what im making now. im just waiting to get my hands on a hondata unit and get it tuned before doing anything else. so for me 221whp/194wtq @ 11 psi @ 3deg retard and 94 octane all the time with no problems

It has been done and it is a daily driver. On a Greddy kit no less. Look at my sig.

thats impressive, good work

bump for the previous question...I didn't know Hondata tuned cars...anybody taken their car there to have it tuned before?

sorry to hijack
but would a t3/t04e 57 trim .48a/r be good for a d16y8 setup

p.s. tried a search already

back to original thread:
around 200-220 to wheels at whatever boost, safely tuned is what i am aming for for my project. I think that will be safe enough for stock internals and if it blows
D engines are a dime a dozen.

If your tuner is worth a ****, you can easily run 10-12 PSI on a stock D series.

Pfieff

I have the greddy kit on my y7 and made 203whp @10psi, i'm going back down to see my tuner on friday hopefully to tune for some more boost. I am aiming for 225whp on stock internals tuned with my hondata s100b.

Happyman

I used to run 8 psi but I'm too boost happy. I'm at 10 now and it runs good. Haven't even messed with my timing lol. I'll have to retard it one of these days. I'm still running ~40 across the board on my afc hack and don't run a bit lean.

what is an AFC HACK????

Snail Tuning

it satnds for Air Fuel Controler. vafc = vtec air fuel controler SAFC = Super Air Fuel Controler.


SEARCH!!!! and would have found this information!!!!

Sohc Driver

involves using a VAFC or SAFC, a high volume intank fuel pump, and some larger injectors. With the AFC hack in a nutshell, you trick the ecu from seeing boost by subracting the map voltage that actually goes into the ECU and also supply the extra fuel needed via the AFC. The AFC hack does not utilize a missing link nor does it have to rely on increasing fuel pressure to the injectors in order to get the needed fuel. The extra fuel is already there provided by the high volume fuel pump...now its just up to controlling the injectors with how much fuel you want to add. The benefits with the AFC hack over the FMU/missing link is that you don't have to worry about overworking the injectors from the high fuel pressure associated with the FMU/missing link, and you can have cleaner fuel map with the AFC hack over the FMU/missing link setup.
