De-cat and boost controller

Recommended Posts

Im sure there are plenty of posts on here on this already but im dammed if i can find what im after.

 

Im trying to de-cat a UK TT. I can not get a socket set in to fit not can I undo the the bolts for the life of me engine side. Is there any easier way to do this.

 

Also where is the boost controller meant to be plumbed into?? I have found lots of threads that talk about putting it in different places.

 

Thanks for any help

Im in Wisbech,

Had the garage do the pipe, took them 1.5 hours with a lot mroe tools than i have had to melt half the bolts off.

 

Still confused with the boost controller. Is a manual one enough or should i get electronic?

 

Any help appreciated, especially if someone can help fit the boost controller

How does this controller look to people

 

http://cgi.ebay.co.uk/TOYOTA-SUPRA-MR2-ELECTRONIC-BOOST-CONTROLLER-VALVE-KIT_W0QQitemZ220397977984QQcmdZViewItemQQptZUK_CarsParts_Vehicles_CarParts_SM?hash=item3350be4180&_trksid=p3286.c0.m14

 

 

I have got : ngk spark plugs, fmic, induction kit behind the bumper, uprated fuel pump, decat,

 

anything else needed? Fcd??

 

Can anyone help me also, there appears to be some sort of air inlet on top of the engine? Is this correct. It is a Uk tt fitted into a j-spec so dont have a bonnet scoop.

 

Still no advice on where to fit the boost controller??

I would have a look here mate for a decent boost controller:

With regards to the FCD, yes most definitley get one as you will hit fuel cut with no cats and it will try and propell you through the windscreen!!!

 

Do you have a restrictor ring on one of the decats??

 

Not too sure on the inlet part you are talking about but i have J spec so i wouldnt know, but by what your describing it sounds like you may be right with it just missing the UK scoop!;)

I have the Greddy profec boost controller fitted and I believe quite a few people use them. I did get the garage to fit this though cos I didn't want anything to go wrong.

 

Its a bit of a PITA to set up but once done "wow" what a differance, it has a low and a high boost setting, and one thing I realy find usefull is it gives you a constant reading of the boost used all the time and you can find out peak boost used too.

 

Mines a UK set up also.

A Manual or electronic boost controller will both be able to raise the boost for you, it really depends what you want and what your budget is.

 

A manual BC is cheaper and once set can be forgotten about, these can be mounted either in the engine bay or plumbed through to the dash. If buying a manual boost controller go for a ball and spring type one.

 

An electronic boost controller usually includes an LCD showing the boost reading, so doubles up as boost gauge, they also usually include a peak warning light/alarm. Some electronic boost controllers allow you to store 2 or more boost settings, which you can switch between whilst driving.

 

More expensive electronic boost controllers include other features such as gain, which helps minimise lag. They can also allow you to map the boost settings against speed, rpms, throttle position, etc. so you can maximise boost through all gears.

 

In terms of EBC's I'd recommend any of the Blitz range and the HKS EVC VI.
