Pls recommend me a boost controller - there are soooo many!

[1JZGTE]

I am after a boost controller. That's all I can say really. Car quite standard, bar filter and planned exhaust system.

 

Now, a buddy of mine recommended a Greddy Pro-B-something or rather as he has one on his 200SX.

 

Now, I know nothing about these and had a look and there are controllers by HKS, Blitz, Apexi etc etc.

 

Which do I go for if I have a budget of around £250? I want something with lost of features, but nothing too complicated if poss.

 

Any help appreciated gents

Greddy Profec-B is a good controller. The Apexi AVC-R is also very good, and has some nice extra features but can be tricky to set up sometimes.

 

You should be able to pick both of those up for about that money, in fact I have a used AVC-R for sale for a lot less at the moment

Well on my peugeot i know dont laugh i run a BLITZ SBC-I COLOR BOOST CONTROLLER, costs a lot but worth it, also run the extra sensors for it, pressure and temp, heres a pic,

PM sent about Apexi

For that sort of money, I would go for the 15059 BLITZ Dual SBC Spec R

what's the deal on a boost controller - do you need one to get to 1.2 BAR? if i dont have one will i only get to 1 BAR?

On the J-spec Supra, removing both cats will increase the boost up to around 1.6bar or above without any boost controller fitted. Basically when the back pressure caused by the cats is removed, the small internal wastegate on the j-spec turbos is overwhelmed and is not able to flow enough exhaust gas to control the spool of the turbos, so they overboost.

 

This is why a restrictor ring is used to create a restriction in the exhaust, to lower the max boost to a safe level. Depending on the size of the hole in the restrictor ring, you could restrict them to 1.2bar and not bother with a boost controller. Or as I use to do on my old sequential set up, restrict boost to say 1bar and then use a boost controller to raise the boost as desired.

 

The turbos will boost higher in the colder winter weather compared to the hotter summer temps. Having some control of the boost allows you to adjust for this.

 

Also some of the more expensive boost controllers have features such as gain % and the ability to map the boost settings according to speed, throttle position etc. The gain feature helps spool up the turbos a fair bit quicker, meaning better response and reduced lag.

 

Normally you would set up your boost controller so you get peak boost when the engine is under the most load in a higher gear, but this will mean you get lower peak boost in lower gears (when the engine is under less load). eg. if you set up you boost controller to boost to a max of 1.2bar in 5th or 6th, you might only make 1bar in 1st and 2nd as the engine is under less load. Being able to map the boost settings against vehicle speed, allows you to set up the boost controller settings so you get maximum boost through every gear.

perrrfect - thanx mate

 

BTW - check your PM dude

AEM Tru-boost is the one to go for IMO, budget not withstanding. It's cheap and very effective.

Ive just fitted a blitz sbcid3 which i picked up off ebay £265 all in, still setting it up but very pleased so far.

the AEM tru boost does look good and fits where the stock clock is. I am a little disapointed with features though. There is no target boost and you can only set the boost controller duty and the wastegate crack pressure.
