Just after a bit of advice really, Im running a 93 UK spec Auto, I have removed the back cat, fitted a Blitz nur spec R exhaust, blitz induction kit, TRD iridium plugs so far performance upgrade wise and am not sure what to do next.!! thought about the HKS BOV but apart from sounding nice would i really gain any performance ?, being an auto box.! and about boost controllers I know I have to get a FCD as well, but is that all you need..??

basically I just need some advice on where to go next for the car, FMIC, BOV, etc etc... and I know there is a limit on the power a stock auto box will take, any ideas much you can run through one..??

 

thanks all

Hi James, have you got a boost gauge yet??. If not then this needs to be your top priority, you may even wanna look into getting a EGT gauge too. FCD or VFCC is a good beginning and a boost controller is good too. As you say the SSQV doesn't actually have that much of a power benifit and is only there for the sound. From there on im in the same boat. FMIC is always talked about, but i read on an America site that it doesn't add much BHP so im still uming and arrghing it. Im also thinking down the root of a S-AFC.

But hopefully someone will be along to correct me etc.... :D

EGT = Exhaust Gas Tempratures

VFCC = can't remember, it just increases your boost pressure warning thingy and doesn't remove it like a FCD, much safer. I really would avise a boost gauge, don't really think it matters which one to tell you the truth. You could get yourself a double pillar pod from Miami GT and get the 2 Gauges put in too. It good having all the power, but it's better to keep an eye on it so you don't break anything.

 

Yeah, you'll need to stick a cat back on for the MOT, that's unless you can befriend your local MOT station :tongue:

Like the others have said, pull that second cat out and you should feel the difference :D When I went double d/cat and zorst I was hitting 0.9Bar max (UK Auto) so, no problem there. Good advice on the boost/EGT gauges :thumbs: next on my list would be the VFCC/FCD (both the same) and if funds are tight then opt for a bleed valve to up the boost to 1-1.2 bar then you will have some fun :)

 

Other things to consider - How is your SMIC ? are the plugs you are using a cooler rating than the stock ones ?

Pound for pound the boost controller will put the biggest smile on your face.

But first fit an FCD, get the other cat out and check the smic is up to scratch (although a fmic would be beneficial).

Once you have the boost raised you will feel a real push as the second turbo comes on song.

if you get one of the digital boost controllers these usually also incorporate a boost gauge and peak hold ( i have one for sale Blitz SBDC spec R for £150 if interested?).

The thing to remember is the more boost the more heat generated, so decat fully to stop any bottle necking in the exhaust and check the IC so the charge temps are kept as low as possible.

 

Hope this helps?

If properly serviced the auto box should take any power the stock turbos are able to produce.

 

If your intercooler is in decent condition then you should be able to run up to around 1.2bar. As has already been said:

 

1. Get rid of the other cat.

2. Fit a boost gauge, so you can see what boost you are making.

3. If you want to boost over 0.9bar you'll need to fit a Fuel Cut Defender.

4. Depending on the boost you are making, you may need to fit a boost controller or bleed valve to raise the boost to 1.2bar.

5. Next I'd fit a Front Mounted or uprated side mounted Intercooler and Exhaust Gas Temperature gauge.

6. I'd also recommend getting the car tested on a dyno to make sure everything is running okay.

thanks pete more friendly advice, deffo going to look for a double decat pipe now..!!

 

If you've already removed the rear cat then just get a pipe to replace the front cat. You don't need to get a decat pipe to cover both cats.

 

It's best to have two separate pipes anyway, so that for the MOT you can just refit the rear cat as it is easier to work on.
