turboing D17A2

bradmanuwf · 09-25-2004

I am turboing my 03 ex and just have some questions.
1. How many cc's are the stock injectors and what would be a good size to get for 6-7 psi?

2. Has anyone had any experience with a map unit called "Missing Link" that keeps the ecu from detecting boost? "Missing Link" MAP unit

3. Does anyone know where I can get some information about converting from a returnless fuel system to returnable? I've seen it but don't know how it was done.

4. Will injectors from a b series work in d17?

5. Will an SAFC-II, bigger injectors, and the map unit keep my engine running well at 6-7 psi? I want the engine to last a long time. Detonation is bad!!!!

The vendor streetlevelperformance on this site is selling return conversion fuel kits I believe. Good tuning for turbo would be the greddy e-manage. Alot of boosted guys also use this thing to send the ecu a fake signal so that the tuning can actually work without the ecu resetting everything.

im not sure about the stock injector size, but i along with other countless poeple r running 9 psi off the so there's no need to upgrade.
b-series injectors will not work but the k series will but u have to modify your rail a lil cuz there longer.

what do you wanna know about converting the fuel lines i have one

as long as u tune everything properly you shouldnt have any engine problems. with our cars its all about tuning!!!!

btw: my kits for sale...

1) stock injectors are 240cc

2) Everyone uses the ML........welcome the world of boost

3) returnless fuel system.........search ........if you want a compete bolt on kit, then contact jeff at www.streetlevelperformance.com

4) injectors from a b series motor will not work.......but rsx-s injectors will fit, they are rated at 340cc

5) stay away from a safc as it has been shown to advance the ignition timing. Get the e-manange and harnesses to get the best out of your motor.

Does the E-Manage have the Vtec controller?
I want to do the Vtec head swap and I see there is a diy
using the vafc, now, if I dont use that, what will controll the
Vtec?

2k2redcivic · 09-26-2004

yes it does but i dont know if any one got it to work right with i vtec...

GLi4dr · 09-26-2004

Thats okay, I don`t want it for i-Vtec...Just for the Vtec on the
D17a...
Thanks

it works, but nobody on here got it to work correctly

btw, a vtec head swap on a sohc motor is a waste of money IMO.........that money could be better off spent on pistons and rods.

For some damn reason my EX turbo kills my budies LX turbo. PSI for PSI both with t3 turbos. There is something there. Dont realy understand why. There just is a difference. VTEC opens the exhaust valves a little more.

4drcivic2k1 · 09-27-2004

That is incorrect. Only one intake valve is affected when vtec is engaged.

Are you sure. My shop who installed my cam told me that it looked like vtec just opened the exhaust side higher.

4drcivic2k1 · 09-27-2004

They were looking at it wrong.

riceburnrex · 09-27-2004

4drcivic2k1 is right. I just looked in my service manual to double check. VTEC only messes with the intake on the D17's.

guns · 09-27-2004

I stand corrected. SO it lets more air in. Interesting. No wonder I was running soo rich when my vtec was not plugged in?

Would that have something to do with compresion ratios being different??
I cant get the civic in Vtec here in oz, only this gay looking 5 door hatch comes with the d17a2, thats why I want to do the swap. I have read that the Vtec kicks harder when you do the head swap.
So basically any computer system that changes Vtec can be used to do the head swap, yeah??
