quick question, once i get my zed sorted ill be looking to try to get a bit more bhp out of it i was thinking of using a jwt chip and boost jest, but my question is could i not use an accurate boost controller like a profec B, instead of boost jets?

 

ill be fitting cooler plugs before i do anything, and a good boost gauge.

One option is 4 pence, one option is closer to 200 pounds.

 

Both produce bucket loads more power than stock.

btw. don't go buying 'boost jets' for silly money, just use welding tips, you get them in 1.0mm / 0.9mm etc.

boost controllers with a chipped ecu makes a bigger difference than boost jets. had boost jets for awhile and it was so so .. then fitted an Avc-r and the difference was massive : )

There's been a lot of debate about this and the answer is always EBC wins everytime. Boost Jets are OK but can cause spikes, an EBC is the best option.

Make sure you buy a good boost guage if you go down the boost jet more or you wont know if your using the right size jet or not.

thanks for the answers,

 

i've got an old profec sitting around from when i owned an S13, it should still work just need to work out how it fits a Twin turbo lol, iirc their is a how to in the FAQ section,

 

does anyone know what would be a good boost gauge? got a few cheap ones laying about but i want a good one, was thinking of one of the kool looking drift iridium ones Z-centre sell.

TwinTurbo covers jets pretty well

cheers

wouldn't just a manual valve be better than jets? at least you could then vary it, as said a good boost guage would be needed, and of course if money is not as much of an issue then the EBC is the only way to go i supose.

you'd never really get both sides perfectly balanced with 2 manual controllers mate...

Were you under the impression that Boost jets were recommended over an Elecronic boost controller (EBC) ?

 

An EBC is always a better option.

 

Boost jets are just a very cheap and simple alternative to an EBC, but they lack the control, safety and performanace a EBC provides.

 

Advantages of a EBC (compared to Boost jets)

- Easy adjustment of Boost levels and different modes for different conditions (eg. Valet, Wet/dry, overtaking, track)

- Boost is built up quicker and stronger offering further performance advantages

- Overboost warnings and protection from overboosting & spiking

- Built in Boost gauge (usually)

 

Disadvantages of a EBC (compared to Boost jets)

- Expensive

- Harder to Install and setup

- User has temptation of messing with boost levels and overboosting; self control and knowledge required.

thanks, i read something similar to the twinturbo stuff on what they did and i couldn't see the point of them over a boost controller imo it seemed like a bit of a bodge, was just checking i hadn't missed something, i'd not heard of them being used, had always gone for manual or ebc,

 

although the faq on fitting a profec B makes no sense what so ever to me? i has thinking i could just get a second solenoid lol, not have to re do half the vacuum lines.

No, you don't use a 2nd solenoid , what you need to do is loop the two actuator feeds together to the one solenoid.
