Alan's Subaru WRX 2.5L PowerUp TD05-20G

Alan's Subaru WRX 2.5L PowerUp TD05-20G


The past setup is perfect for 20 tiang races, running a VF28 powerplant on stock internal have brought much glory and wins for the owner. Now, the lack of top end power has been bugging the owner for a long time and the desire to run 30 tiangs itch has caught up and convincing enought to go for a 30 tiang turbo. We dropped in a TD05-20G, a similar turbo as the new Lancer Evo 10.

A scheduled race has been setup and the need to setup the car in time for that race get our hands and hearts pumping.

The TD05-20G in a wrx has to be carefully crafted, the diameters of the piping and core size of the new front mount intercooler is very important, modification has also been made to the bumper areas to ensure air gushes through the intercooler and not around it.

Car has been setup with twin plate carbon racing clutch, fmic, td05-20G turbo, big injectors, and tuned using ecu reflash method. Full boost at 3500 rpm!

Here goes, on the first run with the Evo 10, both cars launched great. Our rex owner is very skilled in this lor... he is one of the better driver around, skill wise, I must admit, he can make a 300 horsepower ride perform like a 380 bhp ride. No doubt about that. Gear shifts is quick and exact, accurate shift points to ensure maximum horsepower is churn from the motor.

On launch, our rex is in front. Gear 1, 2, 3, 4.... on 4, we are already 1 chicken farm length away from Evo 10. Hahaha. Kudos to Alan!!hahaha!!

Ok, now, Evo driver is a young chap, he say his gearbox la, this la that la... then rematch lor.... Ok round 2....

On the 3 horn, both car will sprint forward as usual. But this time, on the second horn, the Evo launches leaving the rex waiting for the 3rd horn... oi yoh... remember inidial D? The dimbo kallang kabot one lor... second horn choing hahaha... anyway. Its really funny for Evo to do this kind of this lor... lucky got video to show hahaha. Our rex lost this round by 1 car length. And Evo cannot pull away.

Lets take a closer look at the Evolution 10. You have a Mivec twin cams anti lag system inbuilt in that motor. You have excellent traction control, you have a very very short extractor to ensure the turbo have almost no lag as compared to rex. This Evo10 comes with modified high lift cams, boosted up to 2 bars and tuned by XXX.

Hardware, i must admit the rex loses by far to the Evo10's hardware. But, driver's skill plays the most important difference in this race.

With a stock wrx internals, our rex in the hands of a potent driver can certainly do us proud.

Next on the makan list, our rex is looking to rebuild his engine to go 1.9bar from his existing low boost setup.... Yes. He won the evo 10 on low boost. Driver skill makes up the loses in bhp... kekekeke... Kudos!

coming soon...
