Well, I first want to introduce myself. I've been following this forum for quite some time but haven't felt worthy enough to introduce myself until I finally completed Phase 1 of my progect. Which was purchasing and receiving my MTD subframe assy from Minitec. My vision with my progect is to build a D16A6 non-vtec motor and squeeze every bit of reliable power and efficiency. All comments and opinions will be appreciated.

Welcome.

Great choice with your engine, I'm planning the same thing.

Ditto on the welcome!

Thanks, I spent months researching available combinations. I'd rather have usable power at all throttle or RPM ranges than being limited to 5K+ vtec. I have a few intake manifolds. Is it worth cutting a Z6 for this or just cut the A6. My thinking is it will reduce the benefits and efficiency of the Z6. I also have a 2000+ IM which has much shorter runners but has larger plenum. Any thoughts?

Nice engine choice Marc, 8) It's a "D" ( But you forgot the VTEC)

Welcome, have you been a member for awhile or just signed up? We seem to be having sign-up probs with new members lately.
I know that you have already got your engine, but I would like to respond to the comment about the VTEC engines having less power before VTEC starts working, or having to get into VTEC before getting good power. Actually, it is just the opposite; The low cams on the VTEC motors actually produce more usable power down low than the cams in the non VTEC motors do. Of course, on the high lobes of the VTEC cams, They also out power the non VTEC cams. That is the whole purpose of having VTEC; the engine is more efficient at both ends of the range, making for a more efficient and easier motor to live with. The only down side being higher up-front cost and complexity.

Welcome! I will just your "D" build with great interest. I think a "D" VTEC is best choice but nether the less congrats and good luck with your build!

While this is true, most Vtec engines have a shorter stroke than their non-vtec counter parts(not d -series though). This tends to shift the powerband up a little which is why they feels less torquey off the line compared to the non-vtec's.

Either of the vtec manifolds are a better piece than the A6. I would personally choose the z6 though.

[mini marc]

If I'm using the z6, can I use those injectors? I read somewhere that I cant with pm6 ecu. Emulsion vs saturation type. I plan on milling head about. 050 to bump Credit to 10.26 with possibly a bisimoto cam. Also... any thoughts on ORBS?

Welcome, Mini Marc. FWIW, I'll give you a double thumbs up on the D-series. I really enjoy mine and I think it has usable, practical power. Keep in touch and show us photos!

Yes you can use the Z6 saturated injectors with the pm6 as long as you don't use a resistor box.

[Tavis1]

Fury, I must say you have been quite a big help to everyone here and I just want to say "thank you" for your time and expertise!

Thanks, but does PM6 require a resistor box? Or are you saying not to add one? Also , any thought on ITBS? (not ORBS) Damn cell phone tries to think for you anytime it doesn't recognize a word or phrase.

Your welcome. That's why I'm here.

All obd0-obd2 Honda ecu's use high impedance injector drivers. Any car that came with low impedance injectors(obd0 civics/integras, obd1 prelude/accords) also used a resistor box to make up the difference. This means that you can use either type of injectors as long as use the resistor box for the low impedance ones.

ITBS only work well if they are designed right. Decent gains can be had on a very modified engine but not so much on a stock engine. D series really need a cam, compression, and head porting before itbs are worth the effort.

[steve]

Great information; I was unclear on the injector differences vs ECUs myself.
