Subaru WRX with VF22 turbo

Subaru WRX with VF22 turbo

Yes, 2 months back also... kekeke...

This ride is recommended to us by another reputable workshop, in the good old days, they specialise in RX-7 or any kind of rotary engines, they are experts in repairing rotary engines, no doubt about that, they still do the same darn good job till date. Their car setup is a little different from us, and, kudos to them, they can do a damn good job too. You can learn a little or 2 from these people and push your own tech forward.

Owner maintains his car at this workshop and which tuning is done by us, he wanna switch from microtech standalone to use standard ecu with reflash. The main reason for this switch is to allow the car to have better fuel economy thats all.

Little did he know that the car ended up with a very strong spool up and high end horse power. We highlighted to him that the current setup is unable to hold the boost at high rpms and requested to have it fixed and come back for re-tuning. Yes, he did come back of course...

ok, VF22 is a very good all rounder turbo, it give very early spool ups and a strong high end powerband. This ride runs mainly on stock internals and stock injectors which we also expressed some concerns in building high boost with this setup. Running the injectors to its max duration is definately not the correct way to tune the ride, so, we settled for less in the end. Until the necessary equipment is installed, we cannot build the kind of horsepower we need.

Usually when sam fixes up a car, he simply aims for a targeted horsepower and do all the necessary to achieve it. Basically, on this turbo, we can generate 350 whp easily on a 2L engine. Whats installed, turbo inlet, vf22, boost controller, and all controlled using openecu reflash... yes, I know, not enough to generate that target bhp. But, owner is happy lor... He is contented with this setup and the tuning. Coz, last time, 1 tank can only run 200 km, now, he confidently boast a FC of 500++ km.

Idling is stable at 800 rpm. No stalling and no cel lights.

There is still alot of potential on this ride and I am definately looking forward to tuning this ride to it maximum potential. Of course, there is no hurry in this la... this kind of play play things can wait one la...

Verdict:
To cook this vf22 dish, you need injectors of minimum 800 cc, preferably a wastegate or something and maybe you wanna upgrade that top mount intercooler to run front mount instead. Then, you upgrade the fuel and ignition system to stablize the entire setup... I think there are a little bit more stuff to add, that, I'll leave it to sam to tok cock over tea... hahaha...
