SupraJames Posted January 30, 2005 Share Posted January 30, 2005 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 james Quote Link to comment Share on other sites More sharing options...
terribleturner Posted January 30, 2005 Share Posted January 30, 2005 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.... Quote Link to comment Share on other sites More sharing options...
merckx Posted January 30, 2005 Share Posted January 30, 2005 Don't bother with a BOV, only good for making a noise. Remove the front cat, more beneficial than removing the rear one as it's more restrictive. Quote Link to comment Share on other sites More sharing options...
SupraJames Posted January 30, 2005 Author Share Posted January 30, 2005 cheers peeps, was looking at the Apex-i boost controller are they any good..?? and have heard that going full decat gives probs with overboost..?? Quote Link to comment Share on other sites More sharing options...

merckx Posted January 30, 2005 Share Posted January 30, 2005 and have heard that going full decat gives probs with overboost..?? Only on the J spec car. Quote Link to comment Share on other sites More sharing options...
terribleturner Posted January 30, 2005 Share Posted January 30, 2005 I think you only get the problems with over boost on a j_spec with these mods. As merckx pointed out, the front would be better, but why not dump them both?? Quote Link to comment Share on other sites More sharing options...
SupraJames Posted January 30, 2005 Author Share Posted January 30, 2005 and sorry for being a complete donut, but what is an EGT gauge, and a VFCC, and i would like a boost gauge, like the a-pillar ones, but again have no idea on makes to get etc....

SupraJames Posted January 30, 2005 Author Share Posted January 30, 2005 im assuming with full decat, when MOT time comes around i would need to pop one back in..?? and thanks for clearing up the overboost issue thats one less thing for me to worry about..!!

terribleturner Posted January 30, 2005 Share Posted January 30, 2005 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 Quote Link to comment Share on other sites More sharing options...
SupraJames Posted January 30, 2005 Author Share Posted January 30, 2005 thanks very much will chat to paul and see if i can get a double a-pillar pop with a boost gauge and EGT gauge to start with and VFCC sounds like amuch better idea, want to keep it safe, will also think of a full decat..! then find a good tuning company round here to do all the work..! thanks again guys as always on here everyone is so helpfull and very friendly.!

Sharpie Posted January 31, 2005 Share Posted January 31, 2005 Like the others have said, pull that second cat out and you should feel the difference 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 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 ?

SupraJames Posted January 31, 2005 Author Share Posted January 31, 2005 thanks pete more friendly advice, deffo going to look for a double decat pipe now..!! SMIC im assuming thats side mounted intercooler..?? well mine is just standard.?? and not sure about the plugs will have to check, just TRD iriduim plus..!

Geezabloke Posted January 31, 2005 Share Posted January 31, 2005 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? Dave Quote Link to comment Share on other sites More sharing options...
SupraJames Posted January 31, 2005 Author Share Posted January 31, 2005 thanks dave, think first things first is a double decat pipe and some gauges, gotta need a fair bit cash, so its gonna have to be a little at a time cause im also doing a complete new ICE install..!

Nic Posted January 31, 2005 Share Posted January 31, 2005 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..?? 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.

merckx Posted January 31, 2005 Share Posted January 31, 2005 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. Quote Link to comment Share on other sites More sharing options...
SupraJames Posted January 31, 2005 Author Share Posted January 31, 2005 cool thanks again people for all your help and advice, I better get shopping then..! front decat pipe first and also boost gauge..!! Think Miami Gt will be getting a call..!! cheers james Quote Link to comment Share on other sites More sharing options...
