Hi guys, i heard phew sound when accelerating, and feel heavy after turning on the AC. I'm planning to send to workshop, which parts probably having issues with those symptoms?

Thanks.

my personal recommendation is YES it is good, provided you buying proper /reputable short shifter kits.
and it is ultimately what is your real intention/objective/goal.

the overall shifting on the stock shifter is decent, but i wish that the knob interfacing is a little closer to the steering, so i had a short shifter and an extender so the shift gating/throws are almost same if not very slightly reduced, however the height of the knob was greatly extended very close to the steering for spirited driving/track days purposes.

so to me, my experience was great as my objective was met.
Muhrica Torque solution short shifter kit does reduce the height a little

and that's a real short shifter kit

so please don't generalize.

your experience probably involved a short shifter and a very short and/or small knob that some people prefers. it basically turns the shifter into a button. some people wants that, and obviously you're not one of them.

Having the same issue here. 1.8MT constantly occasionally jerks when trying to move in first gear (especially during jams).

1. Belt area has obvious grinding noise when AC magnet clutch triggers.
2. Spark plug changed Denso Iridium
3. Tensioner pulley and serpentine belt changed still has the same issue. Had some squeaks immediately after changing to Lucas 6PK2563 belt, then workshop offered to change to 6PK2565 instead. No more squeaks but comes the phew sound during accelerations

Jerks as in clutch not fully engaged? Might be your clutch pump.

I think its fully engaged, because first gear runs fine, the jerk as in suddenly losing power.
It becomes more obvious when the AC is on, when the magnet clutch trigger then the loss of power can be felt instantly

Tried cleaning your throttle body?

When is the last time you change ur clutch set?
Mine around 100k it start to jerk/slip/power lost. Stock 1.8mt. Change clucth kit problem settle.

Tbh I don't know, only got the car less than a year. but already 200k. Previous owner drove for a year but never did any maintenance

But engine was smooth and power felt ok except when aircond is on. Also sometimes have difficulty disengaging from first gear. I suppose gearbox maintenance is sooner or later 

Difficulties in engaging gear or so , or goin up car park ramp  feels like power loss/slip/jerk with 2nd gear, all these lead to worn out clutch issue, for gb oil i'll recommend redline mt85, you need 3 bottle. Clutch kit go for ori part exedy kit is good enough.

Damage for parts itself should be around 900+ for clutch kit,  300 for gb oil. Excluding workmanship. Prepare some extra incase both clutch master and slave cylinder are rotting. Change them out as well.  It will be around 700-1k for ori parts. Do not use oem clutch master and slave at all cost.
Once fixed ur car can be trashed another 5 year or so with peace of mind.

I see, thanks for the estimations. Get myself prepared for the pain. 

Btw, I finally got the throttle body, MAF sensor and K&N Filter cleaned. The hesitation is still there, I don't feel any obvious increase in power, but I did notice through OBD2 that the "Throttle Position" during idle went from 11.76% to 9.8%~10.2%. Not sure if I should be happy about this, would this slightly improve FC?

In the meantime, I'm waiting to have my AC compressor replaced to see if this may change the hesitation.

Another question, my power steering has been whining a lot during idle and sometimes it gets heavier despite changing idler pulley and tensioner already. Any ways to diagnose it?

Car feels heavy when AC engaged.

my guess.

1. Your AC compressor bearing is bye bye, sudah JAM, so it takes a lot more effort to run it

2. Power steering making winding noise - Could be caused by your AC Compressor, as it runs on same belt, AC slow down the Belt in turn slows down the power steering pump.

3. Power steering fluid is contaminated - try flushing and changing new fluid

Sekian.....just my 2 cents

Hi everyone, just wanted to ask where did you guy buy the air filter? Engine bay that one.

Just found out that my air filter seems like does not fit properly and leave a small gap at the corner.
