TOPIC: Engine Upgrade

Engine Upgrade 5 years, 2 months ago #563

sir,

good day sir, kakatranspalnt ko lang po ng 4efte sa EE90 na everyday driven car ko.
My setup is 4EFTE with LSD, mostly stock na po lahat... balak ko po sana magtaas ng boost para medyo lumaks ng konti , anu po ba maganda ko idagdag? balak ko po kse Drag set up sana...

Dati npo ako nag lalaro ng Drag but it was during highschool days pa, mga 94' pa hehehe, at mostly schoolboy cars lang gamit...

Hi,

Pwede mo itaas ang boost hanggang 14psi lang. kailangan may boost gauge ka. anything above 14psi, mag mamap limit na ang ECU. Pwede ka mag lagay ng fuel cut defenser (FCD) para ma overcome ang map limit pero kailangan pa re tune ang ecu.

Salamat sir sa quick reply, I will try the mods na cnbi mu. Will keep you posted po after the addons.kung sakali po ba binabalak ko kse itaas ang boost ng stock 4e up to 20psi. Kakailanganin ko po ba ng mas malking turbo?

Ty more power

Sorry for the late reply.....as long as your a/f ratio is okay, pwede 20psi....pero its better kung nasa conservative side ka para din sa safety ng engine mo...usually, at that booost, kailangan upgraded pistons.
