dyno result turbo d15z6
I know you all guys dont know my engine its unique in europe.
D15z6 114HP stock E-VTEC
i have a K03 turbo, h22 injectors, BOV ,VAFC, missing link
and all the bla bla needed.
Iam only hitting 155HP and 230 nm @3200RPM but @6800RPM i have less than 140HP
what can be wrong?
is my wastegate fucked up or is it the mbc regulator?
Iam pumping at 1.1 BAR
how much should i run normaly?

Re:dyno result turbo d15z6
You're running over 15psi? 
Wow, what has been done to the motor?
If I were you I would trade the H22 injectors for some 450cc DSM's and ditch the missing link.
What are your settings at with those tiny *** injectors?

Re:dyno result turbo d15z6
Well the E-VTEC was released here in Canada in the early 90's, It didn't really fly so I guess they pulled it.
The things I would say to consider is
1. The amount of fuel you are running at the higher rpms could really be ------- you up.
2. E-VTEC is made to run really lean and have excellent economy maybe you should look at what is happening with the system at higher revs, is it even switching the rocker lock over? I mean is VTEC engaging?
3. At 1.1 bar you may be out of your turbo eff. range, or are you counting atmosphere? Calculate your CFM values without your turbo and with.
4. I would remove your missing link and use the VAFC properly with a BTM or someother timing retard.
Your bottom end sounds solid but something must be wrong there, you are losing WAYYYYY to much power.

Re:dyno result turbo d15z6
I have: D16A6 head, D15b2 head ( same as A6 ), D16Z6 head,a vtec-E head, and the vtec-e is a POS !!! Its like a HF head with 16 valves !!! Its total junk !! I couldn't even give mine away !!! I got scamme don ebay ( was described as D16Z6, and I payed $225 shipped for it, ouch !! 2 years ago.. ).
I think with a simple ECU swap and D16 comparable head ( but more HP minded ) You'd either blow the motor up or get fast as hell..
My friends had a JRSC and ZEX 55shot on a 230K mile HF motor !! He ran 2 bottles though it and the S/C for about 6 months, the motor never died b/c the head/intake just couldn't flow the air, and the seal were to worn to hold the cylinder presures..
Turn the boost down, swap the ECU, and the head, then kick some *** !!
I'd think the car wouldn't wanna run or would even knock b/c I thought the vtec-e motor/ecu was designed to run super lean for gas milage, and super lean + boost isn't good.. But I guess your not have a problem with that..
140Whp is pretty good, if you could see a side by side comparison of the vtec-e vs a A6,Z6,Y8,Y7 head, you'd ----...

Re:dyno result turbo d15z6
i had 400CC injectors before and they sucked ***
they were from a lancer turbo, the pluggs didnt fit and i had to change them.
the fuel consumption was terrible and the afr far too rich.
i could not go above 11 basicaly i had fuel coming out of my exhaust.
yesterday i spoke with some guys on the homemadeturbo chatroom and it might be beacause of my turbo.
its the K03 used in audi s4
however its 1.1BAR its not giving enought air flow and thats where my problem is I guess.
I think i am going to save some cash to buy a seperate computer unite control, something like the motec or Unichip

Re:dyno result turbo d15z6
youve got the same motor as me 
Could u post your internals.Im doing Y8 head swap at the moment cause the vtec-e is ----.Im going to be running The Y8 head ported, garret T3 ,Large Fmic,450cc,VAFC,D16Z6 ecu,Custom plenum ,85mm throttle,LS Rods ,arp bolts,HKS filter,255 pump. Im chasing 300hp hopefully ill get it.I dont no what comp im going to be running with the y8 head ?But yeah good on ya man for building something different.
