Sudenly I am forced to ask this question: How much psi boost can a stock e16s engine take?
Some of you might know that I am bolting up a set of sidedraft weber carbs to my engine. Whilst talking to people about manifolds , cams and tuning I came across a cheap supercharger. It comes of a Mercedes and boosts 6 psi.
I think you'd need some bottom end work at least, maybe headwork too.
Also I am not sure if those webers are up to the task. Not in terms of volume of delivery, but in terms of atomizing the mixture, and spreading it evenly in all four cylinders.
With all the work and tuning you might be better off installing a JDM E15ET. I am positive you can get one down here.
I am not woried about the Webers. They work with supechargers all the time. Also sidedrafts are equal to one carb per cylinder and can be tuned infinately for delivery and atomisation. If i do go that route it will be a low presure setup 4psi boost or so. That should work well with stock internals.
This project will be a test bed for a future all SR20 project. I am not looking for high revs and scorching top speeeds. What I want is an engine that delivers all the goods below 5500 rpm. A daily driver that remains fuell eficient while having enough shove to scare the guy challenging you at the red light.
This is exactly what webers and supercharging offer: a big fat toque curve.
a stock e16 can take lots of boost, its a very strong engine and i wouldnt worry about low levels of boost from a supercharger, if you get a turbo and start boosting like 20 psi then i would worry, but not from a supercharger or small turbo, and i think the e15et can take up to 20 psi with stock internals, you should swap the carb for fuil intection though, from an e15et or from a ga16i possibly(but will need to somehow get more fuel cause i've seen a turboed ga16i and the fuel could not keep up after around 6 psi)

Who knows can the E engine handle that?
what mercedes?

I wouldn't think the stock fuel system would be up to the task even with a little boost. If you just found an E15eT and converted to an E15eS(S for supercharger of course) I would think it would take care of alot of concerns.
I have no idea, I've been flirting with the idea of a CA18DE-S or R whatever, but I think I'll just do turbo with the sentra and save the super idea for something like an S12 so I could actually get the torque to the ground.
why put a supercharger on the e15et when you can just upgrade with say, a t25g , or t28 or some sort for the same price, you'll get way more power out of the bigger turbo
PS: The fuel system will be upgraded. No FI , but high volume low pressure fuel sytem. The guys on the V8 scene does this all the time. I still contend that fuelling via twin webers and electric pump will be adequate. The weber emulsion tubes, chokes, main and idle jets can all be adjusted for maximum fuell and air flow.

I still think atomisation will be the issue, betting 'lean spots' and then pinging. South Africans know their carberators though. Most cars still have carbs down here, and they are crazy about Weber. So if you think it's a gonna work, we'd love to see it.

pinging you fix by retarding the timing. but with that little pressure i doubt it would be an issue.

My weber setup requires that I relocate the pipe from the brake booster to the inlet manifold. Will it work if I allow the pipe to take vacuum from the exhaust?

umm...vacuum from exhaust??? what the...
