New SBR Intake Manifold....How well does it perform?

[Syndicate]

oops forgot to mention something real quick and the EDIT is not letting me edit , just brings me back to the reply screen .. Anyway with physics involved its more about the volume than any of these designs . The design should be your engine volume ( 2.0 2.1 2.3 2.4 etc ) + the amount of air you are forcing in , with some oddball im to stupid to figure out calculations .

Anyone want to take a guess at the volume inside the oem intake manifold? .. pretty sure its close to 2 , alough im not wasting my pepsi to find out ( ran out of coke )

don't be knocking on wood. On my mudding truck I use a piece of 1 in plywood as a carb spacer/heatsink. Otherwise I would get vapor lock.

The only reason I I said anything about having to big of a TB was related to a N/A carb scenario, where if you have to big of a carb the engine will fall on its face for any type of torque. But with Fuel injection I haven't ever really seen anything that would be a "to big" is a problem since fuel injection is a metered air system versus a carb is all vaccuum and "dumb" system.

well my SMIM is 3.5x3.5x16 long, which is 196 cubic inches (497cc) of Plenum volume . And four runners at 6x2.5x1.5 which is 22.5 x 4 = 90 CI + 196 CI = 286 CI or 726cc

with the stock one I will assume for lack of having a manifold in front of me 60mm bore for 400mm long which is 70 CI for the plenum. As far as runners I will assume 2.2"x1.2"x12" which is 31.6 CI x 4 = 126Ci + 70CI = 196CI = 497cc

There ya go.....you know the only thing you have to worry about stateside is the 300zx.

Did you miss the part about the Skyline? In the area we have several real Silvias (RHD) and many 240sx conversions. A few 200sx turbo (also SR20DE and 1 SR20DET), and of course the 300ZXtt.

Never met a Nissan that I couldn't walk all over.

A trip to japan should change that idea. As some one mentioned here they didn't understand the hard on for nissans in JAPAN, you mentioned thee above (I tried to point out you are not in japan), but I think you just want me to agree with whatever your saying for some reason so I'll stop.


Apparently you know some slow nissans and that is supposed to change what I'm telling you. I just got back from japan last month, there was a ton of fast nissans. Saw alot of early evo's too, think thats why they don't care much for the eclipse. Supra and Skyline, as common here as mustang or camaro. Japan also has better cell phones for some reason, sorry if it's shocking, but they do.
