Not sure about these mods

[chrisJDM]

I have recently been spending money on uprating my intercooler and fuel system etc and there are a few other mods i have looked at and am not sure wether it is worth getting and dont really know what benefit you get from them.

1. Light Weight Pulleys
2. Performance Spark Plugs
3. Thicker Plug Leads

I have seen lots of diferent ones for the FD and am not sure about them, Are these mods worth doing? whats the best ones to go for?
Cheers

i have a set of dragon pulleys fitted by ross very good bout £100 aprox

[chrisJDM]

did they make much difference??? what was the benefit of having them??

Pulleys are realy just there to make the Waterpump pulley bigger so when you get rid of the Air pump as part of a Decat, they just give the belt more contact (so it doesn\'t slip)

The Plug leads, Well they will only make a diffrence if yours are Shot, i personaly would not put "Thicker" ones on as i have a set of 10mm leads and they don\'t fit properly.

Plugs, well if you use NGK\'s you can put a Grade hotter plug in if you do alot of Track days etc or have a mildly Tuned car but there is side effects hotter plugs Foul easyer and last less time if you use it every day (low speed etc)

What sort of Spec is your car? do you have a PFC and all that sort of stuff? you may find more benifit Getting it Serviced and set up by a Tuner (bit more Boost)

[chrisJDM]

spec list:

Apexi Power Fc and Commander
GReddy Air Intake Kit
GReddy FMIC
Nippondenso Fuel Pump
1600 cc Secondary Injectors with competition Fuel Rail and regulator etc
Performance Downpipe
Silenced De-Cat
Apexi Back Box
Bailey Dump Valve
GReddy Profec B Boost Controller
Removed Air Pump and Air Con

This is a list of what wil be done on the car after about a month of so, i have some of the parts and still waiting for some of the others from usa.

Are you still on stock boost?

[chrisJDM]

currently mapped to 0.85 bar but might put it up a little once the FMIC and Injectors are fitted, will see what the guy who maps my car recommends

[Grizzly]

I supose it depends on the Condition of your Turbo\'s, you can run 1 bar but its on the Limit of the Stockers.

[chrisJDM]

ive got quite high mileage aswell with no rebuild so dont wanna push it too much

I supose it depends on the Condition of your Turbo\'s, you can run 1 bar but its on the Limit of the Stockers.

Unless you are a nutter like the Hog and ran his at 1.4 bar and they kept going.:2eek

[Grizzly]

1.4!!!! Wow i had an fd set up to 1 bar and it took 4 months for them to go pop.

How long did yours last? I guess it depends on Condition and how you look after them i supose but i don\'t know many Turbo\'s that don\'t have 360 bearings to go much over 1 bar without seeing seal blow by.

[Rixio]

Mine have run at 1bar since it was built with the only problem being fuel cut at 5300rpm due to stock injectors...that was until the front plate broke anyway...

If you are not sure when last the leads were changed then I would change leads. Thereafter plugs - iridiums.

Err, I think you meant to say you would fit a COLDER plug for track days, and a colder plug would foul easier.
