We were discussing with my mechanic/tunner how to get 330~350hp in a 2003 70k miles 350z in pretty good conditions (which has a 5/16" plenum spacer, long headers, cats delete, 3" exhaust and fulltech 550 ECU) producing 290whp, 248tq. He proposed to adapt a Toyota Yaris/Vitz or Levin supercharger and make a 2" hole (may vary of course) in the intake manifold (like in the HR) to get the FI.

Some context: car is used only for casual drifting and having fun, will make around 1000 miles or less per year. Where I live, getting an specific 350z supercharger will take 6+ months (with the chance to lose it in the way) and end price would round 15k USD, so, it's a definitive NO-NO..

I understand this is not the best idea or way to get FI, turbo is also an option, but I would prefer to stay under 350~380hp and have a more consistent power delivery since the car is only used for drifting...

I would like to know your thoughts, do you think this would work as I'm thinking it will?
Do you think I will get those ~50hp gains (or any) with this mod?
Do you have any other idea to hit 350whp? (as I investigated I'm almost in the limit of what bolts on can get)

 

You want to put a 1500cc supercharger on a 3500cc motor? I'm not going to do the math, but you might see half a lb of boost at 7k rpm which may be good for about 10hp

 

I'm indeed also afraid of that..... I don't know enough about superchargers.. so, your comment makes me think it could be a bad idea.

 

There was a guy who installed an eaton m90 on the stock plenum and drifted without a hood.
He didn't post about the build, but it worked. If you can do the fab work it would be cheap.

 

Thank you sir! I think I found that threat.
