Of Gauges and wastegate

[turbolover]

Hey guys,
I have a 4g93T under my hood and have had this lovely engine for nearly a couple of years now.Did no bother about installing any boost meter or whatever as i don't find the need too.stock standard.but suddenly got the urge to fix some gauges.what is the most important gauges for a stock baby.i'm sure boost meter will be the most important.what else comes next?oh yea i dont even have a timer.Oh if u guys can list down the gauges by importance it would be very helpful.if brands of gauges even better.
Second thing is i have a 44mm wastegate.can i fit it into my stock power plant?what r the charges if one were to get it installed?

Thanks!:wavey:

boost gauge
turbo timer
oil pressure

Thanks skywalker for the first post.anyone else can help me with the wastegate?

wastegate basically will be not necesarry as ur GSR is pretty stock though...

 

[SkYwAlKeR]

if u plan to increase ur boost level, u need a wastegate...

Hmmm yes i thought so but since i have a 44mm wastegate(which i think is too big for a stock GSR) i would like to fix it and wondering it can be done.What r the consequences of having such large diameter.will the wastegate open?should i dump the waste pipe out or back to the exhaust?Thanks for the feedback guys.

exh temp meter!

For gauges, you can refer to this page.

Since you are running on stock setup. You don't need to add a wastegate. The stock actuator in the turbo should be able to handle the job. Unless you will change to a bigger turbo or boosting more than an actuator can handle.

I'm driving NA, and i installed water temp, oil temp and oil press, to monitor engine condition, if i BOT my vehicle, i will install boost meter and exhaust temp... heard that exhaust temp is crucial to detect whether engine knocking or not...

exhaust temp crucial to monitor combustion temperature... if mixture too lean, combustion temperature increase... if mixture rich, temperature reduce...

if temperature is high, high chances dat it is knocking/pinging inside...

to monitor knocking issue, best to get a knock amp....

Previously i was driving a GSR rojak with a TD05 single fin boosting 0.7bar.Had a exhaust temp that was faulty after the temp went too high.so got a a knock amp whereby when i'm before it boost it's on lean but rich when i boost.Is this normal?

knock amp only show if there is knocking happen in ur engine... not much other benefit already.... best is u invest in a wideband o2 sensor... can monitor ur AFR mixture all across the rpm range....

It will be normal when the mixture is rich when you hit the boost range because extra fuel will be need to obtain a correct AF ratio as more air will be forced into the engine. Imagine when you walk slowly, you inhale less air right but when you suddenly sprint or run your lung will inhale more air so that you can have more oxygen supply.

rich AFR setting also good to eliminate excessive heat generated..... reduce combustion temperature, reduce detonation, etc...

piston is kept cooled by excessive fuel.....
If you are a dragger or a track goer, use octane booster to prevent detonation.
