Polemarch Posted October 21, 2004 Share Posted October 21, 2004 Hi everybody. I will be buying my TT Supra quite soon and plan on doing some basic upgrades quite early on. I like the sound of the BPU level 1 upgrade that suprastore offer (it's ok to mention companies here right?). They suggest the following 5 items plus an uprated fuel pump (for non UK cars). 1. Downpipe 2. A'PEXi N1 Exhaust System 3. GReddy BCC 4. GReddy Profec B-Spec Electronic Boost Controller 5. 52mm Greddy Boost Gauge. I was wondering what your opinions are on this kind of upgrade? Are there better ways to go? Would you import the parts and get a company over here to fit them, fit them yourself or get a shop over here to do the lot including getting the parts? How much roughly would you expect to pay for this kind of uprgrade including both parts and labour? Thanks :-) I'd like to do some or all of it myself but I'm not that convinced of my automotive abilities! :-) Quote Link to comment Share on other sites More sharing options...
CJ Posted October 21, 2004 Share Posted October 21, 2004 The general consensus of opinion is not to touch Suprastore or Titan motorsports with a barge pole as their customer service sometimes leaves a lot to be desired! As for the first mods, you probably will need something like the following: 1. A better exhaust system (RSR, Blitz NurSpec etc) 2. Full de-cat 3. Fuel cut defender 4. Speed de-limiter 5. Boost controler (I used the Blitz IBC SD3 and found that Very good) 6. Boost gauge. I am sure with far more technical knowleedge will be along shortly to give further / better advice Quote Link to comment Share on other sites More sharing options...
Polemarch Posted October 21, 2004 Author Share Posted October 21, 2004 Thanks. I was hoping just to use their store as a guide to some of the things I would need :-) What's the deal with importing the parts these days? Is it still cheaper doing it this way or are the parts in blighty not too bad? Thanks. Quote Link to comment Share on other sites More sharing options...
salvatore Posted October 21, 2004 Share Posted October 21, 2004 Stick with blighty m8! Importing stuff can be a pain, takes ages, and if you end up with the wrong stuff (like i did from Suprastore), an even bigger pain. Have a look in the traders section here, plenty of excellent companys offering good prices and cool kit! Quote Link to comment Share on other sites More sharing options...
Polemarch Posted October 21, 2004 Author Share Posted October 21, 2004 Ok. I suppose the big question is where do you start and then work from there. I am not looking for anything crazy (yet!) so i suppose the basic idea of the bpu parts listed above would suit me for now. I'd like to get somewhere around 400BHP but am happy todo it in stages to keep it affordable and so I can keep an eye on what is happening. Presumably the downpipe and back section are the firsy two bits to work on right? I'm not into loud, farty cars (no insult intended!), more into something a little more subtle. Recommendations?

Jake Posted October 21, 2004 Share Posted October 21, 2004 Assuming you are getting a J-spec TT, it's likely to have a non-standard exhaust anyway. The biggest difference to performance will be gained by removing the cats. In your situation my first mods would be: Full decat Boost gauge. Uprated fuel pump Restrictor plate Fuel cut defender Speed de-limiter I wouldn't worry about getting a £300 Boost controler just yet. A decatted J-spec makes plenty of boost anyway. Your problem is likely to be holding the boost down to a safe level (hence the restrictor ring on my list) rather than needing to up it with a boost controller.

outatime Posted October 21, 2004 Share Posted October 21, 2004 Get in touch with Chris Wilson ([email protected]) about some de-cat pipes, he will give all the advice you need. Like the others said, you will need a fuel cut defender (TRL VFCC) if you get a backbox along with a full de-cat. A boost gauge is a good idea once you start messing with the boost.

Nick Posted October 21, 2004 Share Posted October 21, 2004 Yep, Chris will be able to offer you sound advice and give the car a good once over. As far as buying from the US goes it depends what you want really. I've only ever bought stuff from MVP and it wasn't any hassle at all. I saved myself a fortune on my brakes and Dusty was very helpful. Quote Link to comment Share on other sites More sharing options...

I agree with Jake, I fitted all of the above and the car runs really nice! I bought a Nur Spec R, Chris Wilson decat pipes, a TRL Fuel cut defender. I fitted them all myself , it's a bit awkward removing the first cat . You can fit them all yourself if you have a bit of experience with working on cars though.

Grazer Posted October 23, 2004 Share Posted October 23, 2004 What about adding some colder spark plugs to that list? Quote Link to comment Share on other sites More sharing options...

I'm not into loud, farty cars (no insult intended!), more into something a little more subtle. Recommendations? decating and non standard exhausts will raise the boost on a j-spec but you will have quite a loud exhaust note as a result, especially with the usual aftermarket pipes. Just letting you know you are in a minority when you say you want a low volume subtle exhaust. I'm not sure which if any i could recommend? if you stuck with the stock cat back exhaust even with a double decat you may not get the boost you are after, alternatively it may well act in the same way as a restrictor ring and keep the boost reasonable/safe. I'd do as everyone says and keep the stock exhaust (if it hasn't got one they are available on here for next to nothing) and see how you like the sound and how much boost you get. After all you can nearly get everything else for the price of some exhausts, and if you're not after a noise increase then why bother imo.

Polemarch Posted October 23, 2004 Author Share Posted October 23, 2004 A little more sound is ok, I just don't want my car to end up sounding like every other WRX out there rumbling away. Saying that, the way a TVR Tuscan rumbles is very acceptable :-) Confused! Quote Link to comment Share on other sites More sharing options...
Clarkey Posted October 23, 2004 Share Posted October 23, 2004 I've got the RSR on my car. What won me over - was that it's got a higher ground clearance to the Blitz. I think there is some sound files on http://www.mkiv.com ... recordings of the various exhausts. Quote Link to comment Share on other sites More sharing options...
Grazer Posted October 23, 2004 Share Posted October 23, 2004 I've got a Blitz Nur Spec with full decat and it is loud - but when you put the removable baffle in, it's not too bad - the baffle also acts as a restriction. Saying that, since I've had the Nur Spec the baffle's been in for about 5 mins! I love the roar Quote Link to comment Share on other sites More sharing options...
