Subaru TS turbo charged

Subaru TS turbo charged

Owner is a friend of Sean who owns a Subaru TS turbo as well.

The project this time is quite unique. We have Mr Car doctor getting his hands dirty putting together a Subaru 2.0 wrx engine for the owner. Sam didnt choose the easy way out, he rather strip the entire engine apart, inspect every single pin, bolt and nut and assemble them back together again. Good engine builders are hard to come by, and the moment finally came to start the engine to see if the bolt and nuts are in place.

For one, the engine idling is smoother than I imagined it to be. I am used to tuning low comp. blocks but, looking at the smoothness of the engine, I can't help but to admit this Sam is good with his hands. I remembered him rubbing the steering wheel and commenting how rough the steering wheel felt in his hands, he kept the back forth movement of his hands, palms rubbing and making a swoosh swoosh sound as he stroke suggestively while looking at me with that dirty smile on his face,... hahaha...

This is a well built engine. Inside the engine bay, we have unichip Q plus, with some of unichip drivers that came along with it, walboro fuel pumps, wrx injectors, the sam-built 2.0 wrx engine block, top mount intercooler, TF035 forester turbo, a string of metallic valves which serves the purpose of controlling boost, a straight through exhaust, meters and many more.

How much did we boost on this car? Well,...high enough to max out the injectors... :) any higher, you can almost be sure the engine will lean out.

While trying to increase the boost, though I have a rough idea of how these metallic aquarium tank valves should work, I have no clue as to how a series of valves stringed together back to back can serve the purpose of controlling boost. Of course, with boost controlled in this manner, it is lesser accurate than an electronic boost controller and it also lacks the finer details of controlling wastegate opening time and stuff which is inbuilt in almost all electronic boost controllers.

Initially we didnt know how to increase the boost... we tried a few times but nothing happened... finally, something Sam did to those valves seemed to be working... the boost started to increase past 0.5 bars for once.... the excitement is back when we resumed tuning the ride.

When I asked sam how these aquarium valves worked in controlling boost, he started to illustrate by showing me with his fingers, how he pull this and connect to that, then turn that and then connect to this and left that alone and stuff... I looked blankly at him which seems to amuse him alot... Though I didnt like the sound of it, it seems to be able to increase boost like a normal controller, but lacks all the finer features which can prove fomidable in a race. I told him, I dunno what the fark he was saying la... He didnt bother to try explaining again, rather, his eyes widen and that smile of his and the way his eyes disects your confused espression, enjoying every bit of superiority in his knowledge,.. oh... I just turned away, mumbled profanity some under my breath and continued tuning the ride...

2 litre low compression engine plus a TF035 turbo. The result? Exactly the same as a stock subaru 2.0 forester. To the owner who was already enjoying his previous setup a 1.6 turbo, he seems to like the way the stock forester turbo felt. After owner test drove his car... he thumbs up to us, smiling widely at the result. He commented on how smooth the car felt. Especially on boost, the car felt fast and very very smooth. Hmm... he seems to like it very much... I then proceed to advise him to change this and that to make it even better ...hahaha

for one, he can use a bigger turbo... then racing clutch, then, better cables... powervalve... front mount intercooler... kekeke... endless list la...

Overall, if you know how the stock forester felt, ... you will know how this ride feels... Of course, to some, like myself... I would upgrade the TF035 to maybe VF34 or something...kekeke... anyway... to each his own. Oh, if you do not like the looks of the subaru forester and wished that your TS felt like it... we can do it this way too... if you ask me, well,... I prefer STi hahahaha.... yah,... so get STI engine lor... hahaha

drive safe! enjoy!
