Single Throttle Body Vs 6 Itbs On Rb26Dett

[MrStabby]

I wouldnt even take the car back .If the guy cant tune an ECU with multiple throttle bodies, or is in any way scared of them, then hes not up to the task.

This.

The other advice is really quite odd too, which makes me concerned that he he either doesn't know what he's talking about, or is ripping you off. Read up more from this forum, in particular the RB26 sticky. I doubt you'll find anyone bothering to ditch the plenum at that power level, or using built stock turbos (which would have to be massively highflowed to make that much power) when -5s are cheap, better tech, and well proven.

Also - is your motor built for that level of power? If not, its very unlikely to last long.

For me, sensible options are;

-9s for around 320-330kw stock motor in good condition

-5s for around 370-380kw built motor, and maybe aftermarket 1-3 gearset (or third will be vulnerable)
