Intake mods??

[Krauss410]

Ive searched all around the forms for something but havent found anything worth it. Is there any way to get rid of the big intake thing(big metal square...i think its called a VAF)? I want to completely eliminate that, and just run a straight tube. Will the car still idle without that pluged in?

If you unplug the VAF (yes that's what it is) it will idle for about 2 seconds and die, you need the VAF to run on the stock ECU

Your not really going to see any real gains anyways.

Alright. Im not looking for a major gain in performance, i would just like more space in the engine bay, considering I have a swapped engine. I just thought i'd ask if anyone knows of a way to eliminate the VAF without hurting the car

Stand alone. With a different air meter........

If you want to do some serious wiring work, you can run the engine on a Civic/CRX Si ECM from 88-91 as long as you have something close to 1.6L engine... but you'll have to change things about the engine, too.

The ECM needs a Cylinder Position Sensor (part of the MPFI dizzy on the Civic), IAT, Coolant temp (won't stop it from running), Singe wire O2 (won't stop it from running), you may need a resistor box for the injectors, TPS (Honda TB's might actually bolt onto our manifolds) and MAP sensors.

Good luck with that, though. You may also be able to bolt a Civic dizzy on our engine, but you'll likely have to redrill the flange to get more than one bolt in, let alone any kind of adjustability. The drive system on the dizzy looks the same. Honda D-series have the coil inside the dizzy, too. You'll either need an external coil kit, or extend the coil wiring to reach the dizzy.

best bet is to go megasquirt if youre gonna change anything about the engine control harness/computer

That would be my suggestion, as well. However, if one were inclined to do all that work, it's pretty easy to multi-map a PM6 Civic Si ECM using a larger chip and a socket kit. You can literally set it up to switch maps at the turn of a rotary switch, and the whole job would cost about $40 and a few minutes of soldering time, not counting the time to program and tune each map or burn the ROM.

But you're still stuck with the wiring and swapping parts around. Although I didn't think about it earlier, I believe our cars have a CPS on them already, and that might suffice, negating the need to swap a Honda dizzy on. Then all you'd really need is the MAP and an actual TPS instead of the "on/off/on" switch we have, at least on B3's.
