Modified by local workshop in Kuala Lumpur Malaysia.

Fully rebuilt engine with Tomei aftermarket parts together with 4G64 stroker
Well the stories behind ~






Previously this car was running in Stock Engine , the owner was satisfied with the performance of the stock standard engine just with some aftermarket parts and boost up to 1.5Bar ....

But........ until 1 day the engine blown , root cause - was using the wrong type of engine oil . I don't want to mention whats the brand of the engine oil but its totally fuXX up , as just barely few hours he changed the engine oil ......the engine blown after the owner was driving at the freeway in Malaysia . End up with the new plan to rebuilt the engine ....

We bring in the Tomei parts all the way from Japan .





















Tomei 86MM Forged Piston and Tomei Forged Conrod fitted in with 4G64 Crankshaft as part of the stroker kit with ACL Racing Bearing. With this , We upgrade the Turbine to Garrett GT35 AR70 with 0.86mm Rear housing The exhaust manifold was custom made from Thailand to fitted in with this turbine together Tial 44MM with 1 bar spring wastegate and using with HKS Racing Type 2 Blow off valve





















Also not forgotten the engine head, Port polish with 45 degree triangular style , with Oversize Valve and Valve Guide ,

Brian Crower 288" cam fitted in with Brian Crower Titanium retainer

Greddy Trust Oil cooler for the engine oil cooling system and the original Skyline GTR intercooler was used.

The fuel line was upgraded to the bigger size to 10mm .
We also not missed out the Fuel Regulator from SARD - Type RJ.

Dont be suprised, we just using the Mitsubishi Airtrek head cover as the original head cover was damage.

For the fuel system , Sard 1000cc injector was fitted in with Sard 265LPH in tank fuel pump and SARD external fuel surge tank with 2 Bosch 044 fuel pump .




.





























The intercooler piping system was custom made by the specialist and the for the exhaust system, stainless steel 3.5" Piping was used together with HKS Hi Power muffler.

For the electronic system , Apex'i Power FC D'Jetro was used for the as engine control unit system and HKS Twin Power for the ignition system , The owner also fitted the Innovate Motorsports Wideband for easy air fuel reading and easy tuning.

For better power and cooling , AEM Water/Methanol spray system also fitted in. After the engine running in for 2 months , We took the car for tuning and dyno session.

And the proud the tuner was the owner himself.





















Weather in Malaysia quite hot and humid.. AFR was set to 11.5 ratio.

Owner tried to push it up to 500whp, Ignition timing was set to almost perfect and the Air Fuel itself was tuned to the best

After a few run , we got 476 wheel horse power, the owner still not satisfied with the power itself
At last 536 wheel horse power was the best result with boost at 1.92bar at 8500rpm ......
that was fun but scary!!!


Owner was satisfied with the performance , the Exhaust manifold was glowing red color as it's damn hot ......

The Mitsubishi Lancer Evolution 7

The standard and modified Mitsubishi Lancer Evolution 7

The Japanese made Mitsubishi Lancer Evolution 7 was introduce in year 2001 based on CT9A Platform with 2.0L Turbocharged Engine (4G63) output at 276hp (205kw) on engine itself and torque was increased again to 284 ft·lbf (385 N·m. Come with 5 speed Manual and also marked the first time an automatic drive train was introduce within this model line up - GT-A

The original Mitsubishi Lancer Evolution 7 was quite comfortable and stable ride. With 276HP on the engine, driving down the road in Kuala Lumpur Malaysia consider a quite powerful 4 door sedan car with a boot!!!



Original with full time 4wd with AYC system ,this car can take the corner like a roller coaster.

Here comes the 2 Mitsubishi Lancer Evolution 7 mod with modification and exceeded 480HP on the Engine

Before that , the owner of this car already push the stock turbine up to 1.7BAR of BOOST!! with Aftermarket ECU and Fuel pump . The owner still not satisfied with the performance and he hungry for more!!!







Now this car can consider as a Mild Modification without touching the original 4G63 Engine Block and its produce 480HP!!!

OK, Now we talk about the process of the modification ,

At first , we searching for turbo kit system , well this really a headache as we have to search a turbine that suitable for this 4G63 Engine. If the turbine is too big , it will cause turbo lag and if the turbine is small, its unable to push a high horsepower on the engine ~ DAMN!!!!





Finally we found HKS GT3037S turbo kit at N1 Racing Sunway and this was secondhand!! Well although it was Used item but the turbo kit really in a very good condition .....and come with HKS Exhaust Manifold system and 44mm wastegate

This HKS turbine design with AR60 Front Housing and rear housing Measure at 0.84mm can consider a big turbine mean for 450HP and up, this might cause turbo lag , In Hong Kong , same car model with the same turbine , they mod and dyno at 630HP!!! Are you sure?







This modification , we change the injector from 560cc to 800cc manufactured by SARD Japan and powered with SARD 265LPH In tank fuel pump with Walbro 255LPH External fuel pump

The engine head also powered with Tomei 270" Pro Cam with Brian Crower Oversize valve (1MM) and Titanum Retainer. The Engine Head was port polish to ensure a better flow system together with Tomei 1.5mm Metal Gasket to get a perfect compression for high boost without damage the engine






HKS Twin Power was added in for a better ignition system , HKS Spec R intercooler system and HKS Racing type 2 Blow off valve also not missed

Then engine block,throttle system , Intake system still remain original and still VIRGIN!!

The engine Management system - Apex'i Power FC L'JETRO

At JC Racing Asia - we send the car for dyno and tune by KIM one of my friend
we felt so nervous...wondering how's the car will perform??? can it really achieve high horse power as expected ?

The answer is YES!!!!!

End up with roughly around 550HP on engine and 426HP ON wheel
Boost at 1.5bar !!! with stock internal !!! that is magnificent!!!

I took the car for a run at one of the highway ~ well...this car perform very well..but turbo lag really irritating me otherwise it's really good to drive around

The respond from 4200RPM the turbo only kick in ~~ and full boost at 6300RPM~ means I have to pull at least 8000RPM to get power

ehh this is Alvin favourite car too~~~!!
