92CivicSiR

I just want some people opinions on how you think this setup will run.
This is all being put into a '92 Civic Si HB on a D16Z6 SOHC VTEC.

Golden Eagle Godzilla Sleeves w/ O-Rings
JE 9.0:1 c/r pistons
Crower Rods
F-Max Turbo Kit
Balanced/Blueprinted
Rods Shotpeened
Crank Micropolished
ACT Stage 3 Clutch
Lightweight Fidanza Flywheel
Port/Polish Head
Blitz SBC I-D Electronic Boost Controller
Tial Wastegate
Blitz DD Blow-Off Valve
MSD BTM Ignition
FMU w/ 2-440cc additional injectors
F-Max Intercooler
T3/T4 Turbo

I know there is something that I am forgetting, but just let me know what kind of power levels I can reach, and how much boost I sould be able to crank into this thing. Thanks.

anybody?

With a fully built block, ditch the MF2 / BTM and get a standalone; Hondata, Haltech, Speedpro, whatever. You're wasting a great block with second rate patchwork/piggyback fuel and ignition control.

It looks like you're going all out. You might want to get stainless steel valves as well.

I can understand why you would say ditch the MF2, but I don't understand why the BTM, will a Hondata retard the timing for boost? I know that the MF2 is the shitty way of doing things, but how much power do you think I can get with that to start. I eventually will get a stand alone system, but I can't afford it right now, so will the MF2 work good enough until I can get a Hondata?

With a standalone you have total control of timing and fuel. You don't need the BTM.

If I were you, I'd do it the other way around, then. Get the standalone and turbo kit and when you get the money, rebuild the block.

Yes... The Hondata does timing retard for boosted cars....

thanks drealgsr. also, the block is already built, just waiting for the group buy on the F-Max turbo kit. Now can somebody answer my other question, will the FMU be reliable to like 12-15lbs of boost for the time being?

DirtyLude

I'm a little confused with the terminology. Most people refer to the rising rate regulators as FMU's. I'm assuming you have an ERL MF2 since you listed the 2 440's and the other f-max stuff.

Do you have enough money for larger injectors? The only one I know running up to 15psi with the MF2 uses larger primary injectors tuned down with an S-AFC to compensate for the MF2, some.

Otherwise I don't know what the limit would be just using the MF2. I wouldn't go much higher than 10 with it alone.

92CivicSiR

Why should I ot go higher. The way I understand it is that at a preset point, the additional injectors start to kick out fuel, is 2-440cc injectors not enough to pick up the slck from stock injectors??

DirtyLude

Anything I say is purely congecture, since I used to run the MF2, but never went near that amount of boost with it. I'm surprised no-one else here mentioned anything. There's lots of posts in the archive on the merits of the MF2, you might be able to get something more from that.

I never had a problem with it (that I know of), but I've read alot of complaints about fuel distribution. Alot the fuel is thrown to the back of the plenum and runs some cylinders richer than others. As you increase boost, the speed of the charge should make that problem even worse, and the amount of pressure is not good for atomizing fuel.

My own MF2 ran fine at 7.35psi, but I'm not certain how much farther I could have taken it.

What I was planning on doing, before I went standalone was running four high impedence injectors directly in the intake runners. The MF2 can run 4 16.5 ohm resistance injectors, and if you can find room to weld injector bosses into your runners, it should be a good solution.

ok great. I was actually thinking of plumbing 4 injectors into my intake manifold and runing it that way. I have heard the rumors about fuel pooling up in the manifold from those injectors being located whewre they are. I think that if I get 2 more 440cc injectors, plumb them into my intake manifold, I will be ok up to (hopefully) 12-15psi. I'll just have to get the whole thing setup, try the 2 injectors, and then try the 4 injectors, and see which works the best. Thanks for your help guys. Any more input woud be great.
