Kelisa Upgrade - Extractor

After a long searching at internet, i finally find the used powerzone extractor for my daily car - Kelisa. She have only 1000cc capacity and run in auto gearbox.

Powerzone is a local car tunning company. Their product are mainly focus on the local car proton and perodua. According to them, this extractor is a tune length design and able to high flow the exhaust gas with minimal restriction. The design of the extractor look good too compare to the stock one.





The stock extractor look like this.






Today, i bring the kelisa and get the extractor installed. It look like this in the engine bay :) Little mod need to done on the O2 sensor wire because it was too short.



Before change the extractor.

3" FGK fujitsubo giken exhaust


New toy for my car. This time is a muffler that come from FGK. It measure 3" for the inlet and it straight flow. Compare to currently i have on my car is from Tanabe medalion and it also measure 3" for the inlet but it have a S flow design.



Although the FGK muffler come with straight flow design, it had a JASMA tag on it. JASMA stand for Japanese Automotive Sports Muffler Association is the governing body responsible for exhaust systems. The member are form by the tuning company like HKS, APEXI, FGK...etc. The majority of the tuning firms are members and the JASMA plate on the exhaust systems means if conforms to their standards, in terms of noise level, usage, and construction. What i care more on the JASMA tag is because its working noise is under japan legal decibel limits meaning not noisy :) Cant wait to have it install on my ride.

Tufoil into my B8

Tufoil an engine treatment from US company Fluoramics. It claims that it will help the engine
  • last longer
  • run cooler
  • start easier
  • run smoother
  • save fuel
  • produce more power
Personally i been using it since my first mazda lantis, then follow by my current B8 and also my daily drive kelisa. I do notice the engine actually run much smoother and more quiet. It cost ~RM60 and actually it quit expensive :P
for more information about the product, u can refer it from http://www.tufoil.com/

Direct power for fuel pump

When the car getting old, the wiring in the engine are being oxidize and the voltage will drop from time to time. Another factor that will cause this drop of voltage is the heat. This is quite obvious for the turbocharge engine because it produce a lot of heat in the engine bay.

Before i decide to pull a direct power from battery to my fuel pump, i did some checking on the voltage that supply to my fuel pump. The BPT/GTX is equiped with a 2 stages relay+resistor for the fuel pump. It will suppply low voltage when the ignition key at ON and ~12v after the engine start. On the stock setup, my fuel pump was getting ~11v after engine is start. This is somehow a bit low from the manual. The worst case is when i pull out the wire on the stock relay+resistor, the fuel pump is still working, by right it should be no more power to it. This mean that during the conversion, the mech was not using the power from the stock relay+resistor and simply get from other source.












Parts that needed for this work:
1. wires 5-6meter depending to ur wire route
2. automotive relay (i get bosch 0332-019-150) any 30A relay is working fine
3. 30A fius
4. sumitube
5. crimb


The idea on this is let the fuel pump get a direct power from the battery, meaning it will get ~13v all the time. And for safely purpose, the fuel pump should stop and the key turn to off. For this to work, this is why we need a relay. The trigger for the relay to allow the power from the battery to fuel pump will be the existing powersource to the fuel pump. The wire diagram i get from Jeff Lucius at http://www.stealth316.com/2-fuelpump-rewire.htm Anyone own a Stealth 316 should refer this site. It provide a lot of information.

First is to do the terminal connect to the battery and also the crimb to that hold the fuse. I use sumitube to cover the join to avoid it to expose dust, water...etc


I pull this wire under the carpet and go to the rear seat. This wire is connecting to the battery +terminal and 30A fius. It later going to connect to the pin 87 on the relay.


Next is to identify the wire that power the fuel pump. Normally there are few wires there for the fuel pump and fuel level gauge. Please refer to ur car wiring manual to identify it. Another way to do this if u do not have the wiring diagram is take out the fuel pump and identify which wires it connect to the pump :) But be careful when removing the fuel hose.
After identify it, cut the wire and connect a crimb on it. Make sure it long enough to the relay else wire extention will be needed like my case.


The wire that being cut into 2 will be then connect to the relay as well. For the one go into the fuel pump, it will connect to pin 30 and the other one will be connect to pin 86. For the ground, it can connect to body of the car and pin 85.

Once all connections is plug in, is time to check the relay is working fine. If u have a voltmeter, u can check the voltage on the cable that connect on the pin87, you will always get the same reading on the battery ~11v before car start and ~13 after car start. Other pin should be always 0v before u tun the key to ON.

To make sure the relay is wokring, turn ur key to ON and you should hear the fuel pump is running. Turn the key to OFF and the fuel pump should stop as well :) Now start your car and you can measure the voltage, u will get constantly ~12-13v to the fuel pump. Next is to use the black tape to cover the connection on the pin. This is to avoid the wires being accidentaly pull off. Now u can take ur car out for few run, then check the wires and also the relay. It should not run too hot.


Pros:
1. Fuel pump getting higher voltage thus provide higher flow.
2. Cheaper solotion compare to replace the stock relay+resistor. Sometime this spare might not even exist in the local spare part shop due to the car is not sold locally or lower demand or end of sales.

Cons:
The lifespan of the fuel pump might reduce due to it work hard all the time. But this is very subjective topic because some newer car model also does not come with 2 stages fuelpump relay.
