So with hood insulation removed, this manifold should fit huh? I wonder if the inferno hood would help out at all with clearance.

 

I think it would be worth it. i could only wonder how much better that manifold would be with a turbo/supercharger vs just using the stocker. I bet you would gain alot of power on a Turbo/supercharger app. Gain alot more flow on the top end. It would lower restriction probally see a drop in PSI. Lower IAT temps then be able to bump up your boost a few PSI and saftely make more power

 

That thing is nasty! (In a good way...)
Ok, who's the Guinea Pig?

Update tired?

 

Bump for an update

post #16 pretty much says it all.

 

Understood. I have a few of those projects laying around myself.

 

Thanks for all the effort. Its a good stepping stone for the rest of us.

 

Maybe this has been considered already, but what about using this adapter and relocating the oil pressure sender:

Sure its not the smartest alternative because you are taking an oil pressure reading pre-valvetrain, but its still an oil pressue reading. Then you could just put a plug in the stock hole in the valley cover, right?

 

Another way would be to use a remote oil filter kit and some fittings...

In the aluminum block above the oil filter there is a port. It just needs to be drilled and tapped.

Found that in the Gen IV section, but I don't know if we have one.

 

Yeah we do, I guess you could drill/tap it, but I don't think you would have enough room to just install the sender right into that hole, you would need to configure it with at least a 90* elbow or something.

 

I think it would be easier to just move it to the rear of the block below the tb. Drill/tap it to line up with the current passage. Then the wires etc would fit without much trouble.

 

how do you think it will fit? The exhaust crossover and coolant pipes are in the way:

 

Looking back, I should have gone with the LS2 valley cover and ditched DOD entirely. That would have made life a whole lot easier. This would have let me go with the FAST intake and LS2 DBW TB. Just a small wiring change for the LS2 TB and no need to make an adapter.

There have been a couple of LS7's shoehorned into Fieros with the intake in the reverse (FWD) orientation that managed to fit the 90mm TB's.

 

Thats interesting. I'm sure there's more room, but my car isn't here right now to check.

 

Yeah but I wonder how much gas mileage would be lost w/o DOD. Right now i avg 17.8mpg and in February when I first got the car I averaged 16.7mpg.

My DOD works flawlessly and I never feel or hear it engage or disengage.

 

Back in 2005, GM advertised up to 12 percent improvement in EPA tests...

I've driven with DOD disabled, which decreased mileage by 8% for the way I drive, so maybe I save 4-5 liters per week with DOD enabled

 

Yeah thats a decent enough drop in gas mileage that I would want to keep the DOD. I wonder if anybody will pony up with the $600 to get the edelbrock intake/fuel rails and see if it clears everything. It looks like the hardest thing to over come would be the air inlet tube to the air box.

 

I know. I'm just worried that sucker will hit the hood. The tubing size difference can be overcome with a few silicone pieces, bigger maf, etc. And a LS2 tb of course.

 

hows dod on a G8 work will an L99 vally cover work bbetter?
