EVO 6-9 4G63 Inlet manifold

PROVEN TEST RESULTS --- EASY 17 kws @ all 4 wheels gained at 2 psi LESS BOOST , with still a complete tune to come .

Vehicle is OEM standard vehicle , with only mod being an exhaust . Boost came on earlier and made more power through out the whole rev range .

100% Australian made by Plazmaman Racing

All required design aspects have gone into the design of this product .

Whether it be a street based , everyday driven vehicle , club car , rally or full open throttle drag car - this manifold delivers.

The basic EVO inlet manifold from factory is well designed , it has long runners for bottom end torque ,

but lacks in plenum volume and has sharp port entry angles .

Plazmaman engineers have spent 18 months in designing and testing similar models

in all forms of domestic and international Motorsport .

The base runners are made in Australia from a PREMIUM grade alloy casting for superior strenght and smooth internal finish

We increase power and torque delivery by firstly lengthening the inlet runner by some

30 mm and then adding a 5 - 10 % larger port , with a smooth tappered style inlet ram tube .

There is a small gradual tapper , from start to finish of the inlet runner .

Careful attention was paid to tapper and runner length , so as to give the perfect balance

of throttle response , mid range torque and big top end power delivery above 9000+ rpms

Careful attention was paid to manifold dome design and shape . To make Horsepower ,

smooth free flowing entry angles and plenum designs are required

Plenum volume has been increased by some 300+ % - to 4.6 litres - this allows the 4G63

powerplant to handle bigger boost levels and rev freely to 9000+ rpm cycles .

Another major advantage of this design is the fact that the plenum volume can be varied to suit different applications

- the dome can be lowered or raised during construction to suit individual applications.

This manifold was designed to utilise the OEM fuel rail , idle motor , alternator bracket , fuel lines , injectors and throttle cable .

All bolt on , incl the full use of the OEM dip stick and location

The plenum has to utilise either a 66mm ( street recommendation ) or 72 mm ( race / big boost )

BILLET PLAZMAMAN PRO SERIES throttle body .

These are direct bolt on applications , and also utilise the OEM cable and

TPS switch ( aftermarket TPS can be adapted if required )

We also have available an adaptor piping kit to suit the OEM piping setup , also available is a full EVO SPEC R piping kit to unleash full power

FOR THOSE WHO ALREADY HAVE OUR SPEC S or R PIPING KITS ,

A NEW PIPE IS AVAILABLE TO PLUMB UP OUR NEW PLENUM .

An after market FUEL RAIL will also be available SOON ,

incl many new products for the EVO series of vehicles .
