| Hey guys I want to know what main things are needed to be modified or changed to be able to supercharge a stock standard soarer. Rather than just bolting a supercharger on what else is included in the job? for example can the tranny handle the power or the diff? Things like that. |

| Hmm well I don't know much about it but logic would dictate at the very least the following would need to be upgraded at the same time: - Brakes - ECU - Diff - Headers - Exhaust (I'm sure you could run it with a stock diff but I don't think it would last long...) |

| If 8k is a lot of money you shouldn't be looking at a blower. You'll spend that again in petrol in the first month.

| Keep the boost levels reasonable - around 6 to 9 psi and all you will need is a brake upgrade. |

| Surely to squeeze power out your best of with an exhaust and a BFI at least. As far as I'm aware (talking to Neil) if you don't go over 250kw you should need to worry about the tranny for a while. I'll be looking at 9psi. the more the merrier~! Don't want to be intercooled though, which I hear is needed if you run 12psi. |

So you're saying as long as I stay at 6PSI all I need to do is upgrade brakes and bolt on the blower (with manifold to suit)? Obviously LSD, Rebuilt Tranny, 440cc Injectors, Intercooling and ECU will need to be done before putting on a 14 PSI pulley ( Eaton MP112 ) But If I can bolt it on and run it at 6 PSI then I can have a little fun while I wait for the other mods. |

| Thanks guys for the helpful replies, I checked my code on my compliance plate I have a A01B which is a factory option Torsen LSD diff? If im correct? What sort of brakes are needed Brembo's or something or even Supra brakes. Just a question for you guys with exhausts, I took my car to a place near by called Dallder Exhausts, and I have had my exhaust upgraded but it only starts from the Resonator Back, its not a cat back, I have gone back and asked him to remove the resonator for me but he has told me it will drone or something?? When I say resonator im talking about the stock factory resonator In the Y pipe. Also the cats I got now are the dodgy government supplied cats for compliance, Im getting them changed to original cats, do you think its gonna make a difference in performance? |

| Get the whole system changed over to a 2.25" twin system. Then get headers with HiFlow cats and an X-pipe. |

| Lynden, that's correct. After that the mods are endless based on your KW objectives. |

| Wafi, I personally recommend the TT Supra brake upgrade. If you have a spare cash like $6000+ you can go big brembo's, but I question their value unless you do a lot of track work. If you have a smaller budget and really question whether a brake upgrade is required at all - I say yes it is and start out with the Soarer TT brake upgrade. Search and you will find a lot on this topic. |

| as for intake and exhaust.... Have a read of the KenneBell supercharger site. There are some great articles there. http://www.kennebell.net/index.htm You will find that for maximum efficiency for the SC the solution is to have no air flow restrictions in or out. |

| For example - when I designed my exhaust setup, I made sure my limiting restriction - the 5" cat could flow more ( 1015 cfm ) than my SC output ( 822 cfm ). |

| Blaine what is your exhaust setup? Twin System or Single? |

| My setup is different than most - see http://www.soarerv8.com/moneypit2005.html for details and a picture. Most of the guys go for Ashley's suggestion - "Get the whole system changed over to a 2.25" twin system. Then get headers with HiFlow cats and an X-pipe." Which I agree is a great system for N/A, but if your planning for a SC then just double check the cfm properties of all components and size accordingly. |

| Personally if I was to redesign my exhaust system once again, I would try a complete twin 3" system and get rid of the 4" pipe with 5" cat section. The problem is where to put the twin cats. For the cats to be effective, they should be as close to the headers as possible. |

| "For the cats to be effective they need to be as close to the headers" For best results you should at least have an extension pipe after the extractors about 16-18 inches before it goes into the Cat.. Tried and tested before and after results N/A cars showed better performance with some more length before the cat. Its all about air speed and flow. If you put some kind of restriction close to the source of the air flow, the air speed will be slower, thus slowing it down easily. If the track is longer and the air has more time to gain speed, the restriction becomes less of a hinderence as the air flow is faster going into it and will exit it alot faster. |

The exhaust gas speed is highest the moment it leaves the cylinder head. Then every centimeter it travels from there on, it slows down.

This works if you completely ignore physics and disregard induced drag in the airflow. Why it flows better further back is because of pretty much the opposite of you're theory. The exhaust gas is slower and therefore has less induced drag as it flows through the cat. Temperature and density also come into the equation, and also have an effect. The actual catalyst works best the closer it is to the engine, as it needs to be hot to effectively work. |

| Mine is getting charged soon, but first Lew has to fit a set of Neils 2 1/2 inch headers, Two 2 1/2 inch high flow cats, then reduced down to 2 1/4 inch full twin system. Lew reckons this will give the best results. He also has to fit new engine mounts, a rebuilt trans with a shift kit, trans cooler, rear wheel bearings, and replace my rear main seal while the trans is out. Then the charger to be fitted, injector upgrade, a piggy back and tune, BFI, and a few other little things to finish it off. I have already upgraded front brakes to Celsior 4 pots and Maltech braided lines. Lew gets my car next week I hope, looking forward to finally getting this done. |

Yea it maybe one of those specially customised extra hi flow cats .... The only problem is they make it difficult to pass the emissions test. |

| No. There is 2 types as in... 1 for close to engine 1 for away from engine. Both different Catalyst's Thats why most Complied Cats FAIL..They are to close to the hot spot.( eg, Pre RAWS Cats ) Eg,, ( Factoy Release ) V8 are on the manifolds, TT is 1/2 way down the system. V6 Commodore, 1/2 way down. Corolla / Camry, near engine. Get it If you want some real nice, great flkowwing Cat's..Nick some from a LATE Corolla / Camry, they are 5 inches round and cylindrical. |

| These OK Neil Well I hope they are because this is what I put on my car hahahha This has 3.0" ends 11" long and 4" round Universal OBD II compliant, Metallic 300 cell core. These are recommended for Modified Turbo, and Nitrous applications. These will withstand higher temperatures than Ceramic Hi-performance converters.
