You could fab some caliper brackets to mount the calipers further out from the centre of the hub and use bigger disc.... To find out if the current disc are up to the task with the addition of an SC. Check out the part numbers for the T-Sport compressor over in the UK.

Once my car is back I'll be pulling out the sportivo calipers and doing some measurements.

The way I find out if the clutch is slipping is dropping it in a slightly lower gear and mash the throttle. You'll feel the slippage if it is slipping.

2003 early build sportivo Only thing I have right now is a CES CAI....not a fan of noisy aftermarket exhausts, but I suppose I'll need to source one real soon to get everything sorted out with the tuning. Thats great news rolla, keep us informed of your guide.

So with the superstrut calipers did you have to end up using the Superstrut disc?? Or did use the disc that came standard with the corollas?

I just ordered the Power FC, estimated arrival time is in 2 weeks. Anyone recommend a place where I can get it installed and tuned?? Additionally after some reading there are problems with the Radiator fan not kicking in due to the fact that the there is no way for the Power FC to send the appropriate signal to the temp gauge on the instrument cluster. Also I have a factory fitted alarm and immobiliser. Would the PFC be able to work with them?? Would it be better to get the PFC to run the engine only and leave the stock ECU to control everything else?? Just trying to get more info before heading off to the tuner. Cheers

Been staring at the DBA catalogue until it started to talk to me. But isn't the zze122/3 center bore diameter 55mm?? or is the standard of Toyota manufacturing that low?? I think only the celica and corolla share the 54/55mm center bore diameter (either get it machined to the right size or get spacers). The last thing you would want to do is get a new set of rims cause your new disc and calipers don't clear your current rims. I've been looking for the superstrut calipers for a while right now and its proving hard to find, I'll be looking into the z32's and GT4 once my car comes back...until then its more searching and reading UPDATE: z32/r32 don't bolt in as the caliper bolt spacing is 100mm

Where?!!!!!

In my quest for more power I almost forgot that stopping is equally important, but seriously don't we all bolt on an intake first or maybe a fart cannon (no offense guys). Right now I'm trying to create a post on how you can go about reducing your stopping distance or increase your braking power. I will also continually add more and more info onto this post as more and more people contribute to this topic. Why?? We all want more power (everyone has there own reason), but reducing your braking distance is equally as important. Whether its avoiding the person that has just jump onto your path on the street or trying to catch up to that Porsche GT2 around the twisties it would all be nice if we could reduce our braking distance. But then again some of us just want to fill all that empty gap in our 18 inch rims. Problem Overheating/wrong temperature range or maybe both If anyone has ever taken there stock vehicle around the track or after a set twisties in the country, you will start to find that the brakes after a while seems to almost not to respond. No amount of cursing in this world will fix your problem while continually pumping that brake pedal. To put it simply your brakes are operating out of their temperature range and are not working properly. So how do we 'upgrade'? List of things that I would look at in order of priority to reduce braking distance. But the first thing I would do is go and do a $14 pedders 28 point suspension check just to make sure your cars suspension has not given up on you. Your braking can be improved with a better suspension setup, but we will leave that for another day. 1. Tyres - The rubber that is in contact with the road. Crap tyres will give you crap braking, end of story. 2. Brake fluid - Really look into changing that at the required interval. The fluid itself is hydroscopic (absorbs water) which means it can corrode/rust your pistons once there is a fair amount in there. Additionally the boiling point of water is much much lower then that of brake fluid you don't want boiling water in your system. Make sure you use a compatible DOT rating for your brake system, your seals, rubber, hoses etc might not like the higher rating DOT fluids. Fluids are cheap. 3. Brake pads - Gives you better 'bite' and one of the more cheaper upgrades for your brakes. Can also be selected to work at the appropriate heat range as well. 4. Brake disc - Slotted and/or Cross-drilled will allow your rotor to cool more properly and allow gases that are trapped while braking to escape and maintain braking efficiency over sustained heavy braking. 5. Stainless steel braided brake hoses - Most factory fitted cars come with rubber hoses and as the temperature of your fluid increases then the rubber hoses can expand and give you that dreaded 'spongy' feeling that you get. 1,2,3 and 4 will generally give you better braking maintained over a longer period of time. Check this out, it contains a list of part #'s for brake and suspension components to replace or upgrade your current gear. Been there done that now what?! So you have done everything possible and still want it to stop faster. We now look at upgrading the calipers and disc. Upgrading to bigger disc will generally have an larger effect then bigger calipers in my opinion as you increase the radial distance from the centre of your wheel. If you want to know why then go back to high school physics or google around. Since usually you cannot usually fit bigger disc with out changing your calipers (could fabricate new caliper brackets) , its best to upgrade both when your stock disc are on their way to heaven (which is happening in my case). Solutions for a big brake kit (BBK) Honestly why did the corolla come with a 4 stud bolt pattern instead of 5 like the celica. Would of made everything so much easier...weird. Project mu They have kits specified for the zzw30 mr-s which might work on the zze122/3 corollas. Willwood The kit in this link is for the scion tC. Upon further investigation (using the DBA catalogue), the Scion tC, Celica GTS, Celica SX/ZR all use the same disc (part # 562). So with that in mind this kit 'should' fit with no issues, other then the fact that the hat on the kit needs to be supplied with 4 stud holes at 100 PCD. TRD USA Once again its a TRD BBK for the celica and matrix. Honestly why couldn't the hubs on the Oz delivered corolla have the same stud pattern. Brash Boy Calipers for the celica in this case which should fit the corollas no problems at all. Interchangeability with other toyota models From my current research... Ae101 superstrut twin piston calipers apparently bolt on to the current corolla while maintaining the stock disc. Pad area is almost double (using mr2 SW20 pads) increasing contact area thus improved braking, its effectiveness is yet to be observed. Celica's (ST185/202/205) They all have the same caliper bolt spacing as the sportivo, which is 130mm. The ST185's came with large single piston front calipers with 288mm disc while the cream of the crop ST calipers came equipped with 4 piston calipers and 315mm vented disc. The Oz delivered GT4 ST185 used 288mm disc while the JDM delivered ST185 used 255mm disc, but with twin piston single calipers. The pad area of both calipers are approximately 50% more then what the current ZZE122/3 calipers are holding. ST185 The twin piston calipers uses the smaller 255mm disc, therefore they do not fit the sportivo without hitting the standard disc.That said, it will fit the zze122 no problems if your looking for an suitable caliper upgrade. The single large piston from the ADM ST185 should fit no problems as they use a much larger disc(288mm), no confirmed fitment yet (will no very soon). Below are visual comparisons of the stock zze122 calipers & pads Vs ST185 calipers & pads. ST202 Apparently they bolt in with minimum fuss, but at this stage I'm not 100% sure. Disc will need to re-drilled to the correct PCD in order to fit the hub. The ST202 celica is the JDM celica that came out with the redtop 3sge pushing out 134kw (IIRC), never sold in Oz so you'll need to look at import wreckers. The following attachment are zip files of ST202/ST205 calipers with dimensions of them courtesy of da_horse over at Toymods. ST202.zip ST205.zip FTO Twin piston calipers off the 2L mivec FTO ALMOST fitted. It would of been beautiful if it did though, would of worked nicely. Caliper bolt spacing is 128mm (I was so upset after bringing it home and realising that 2mm is such a huge problem). You could elongate the holes to get them to fit......But I would not recommend it at all. Dimensions on stock calipers Caliper bolt spacing is 130mm. More to come as I take them off completely and provide more detailed dimensions. Any information supplied in this post or thread is purely based on my limited research on the internet. I'am not liable for any injury, loss, accidents etc if by using this information it cause you to experience undesirable consequences.

The superstrut calipers are basically impossible to find at the moment, unless of course you are interested in purchasing a complete halfcut. If they are twin piston pots, then I think they are the earlier model gt-4's (ST165/185). The ST205 have 4 piston calipers at the front with huge 315mm disc at the front. After getting my quote from a few suppliers and the fact that there is a 2-3month wait on the greddy supercharger kit, I'm not going for it. Price is kinda ridiculous if you ask me, 25-30% markup not including delivery (eat my shorts). I could source it from the states, but would be a pain if any kind of trouble occurs. Going to start a new thread in the brake and suspension section regarding brake upgrades now.

Blitz only fits the 2zzge, for that matter I think only the 1zzfe had the TRD setup available.

Toyota did build an 8A, its called the 2s series engine which of course evolved into the more popular 3s series

n11rice yours and mine look exactly alike, except that I have a white rolla. Its worth it I tell you, to this day I haven't gotten a sub because of sound deadening.

I believe that is the blitz kit thats on the photo up top. Blitz kit will set u back quite a pretty penny, IIRC its around about 7K landed in australia (prolly 10K fitted). It has much more potential then the greddy kit as it comes with an intercooler kit as well. Whereas the greddy is similiar to the TRD kit for the 1zzfe as it has no intercooling option., unless you go custom which is not worth it clearly. Currently getting quotes here and there, just need to wait for the people to respond... <_< Also searching for brake upgrades (calipers, pads and disc) I've never thought of the motor mounts, time to do more reading Cheers

For the greddy celica kit going onto the sportivo 1. Fiddling the fan shroud and radiator?? / Do I need to go custom? 2. Relocating the radiator fluid reservoir?? 3. New Battery (maybe relocate)?? / Factory battery needs to be replaced anyway 4. Brake upgrade to pass engineering?? / ae101/GT4 levin calipers, braided brake lines, brake pads/disc/fluid?? 5. Suspension to pass engineering?? / running on stock does it need to be upgraded? Would hope that maybe someone has done prior research to a similiar project and would like to hear there views. If anyone brings up that SC Vs Turbo debate, you'l'l hear from me no doubt Seeing that the greddy kit will prolly only 25-30kw boost in power, I figured that since its not as extreme as xoom's corolla I might be able to get away with a few things. Already have an aftermarket clutch we will see how it holds up. My best bet is to call an engineer, I'll need to anyways. But just putting this up for the sake of discussion. Cheers

Hopefully no one got their hopes up too high... Is their any supercharged sportivos that anyone knows of in Australia?? I did a search and from my poor memory I don't think there is. Cheers

Did all the sedans come with the two tone interior trim??? I've only been in an ascent so I'm not sure how the trim would be in the higher spec models. If thats the case, then only two things annoy me. 1. two tone trim in my opinion is absolutely ugly 2. hatchback looks better

So is it the fact that its a CAI so that it produces more power on the dyno then a SRI, both with the bonnet open..... OR The inlet tract length The way that I think is if your bonnet is open then underhood temps shouldn't really affect the SRI, but we consistently see that the CAI will produce more power. I'm thinking that the length of the inlet tract is the reason the power is being made. Cheers

If you truly are looking at obtaining that figure then continue saving your money and get a piggyback ecu and maybe a set of cams to get oh so close to that magic triple digit.

Play nice now guys, I couldn't even be bothered anymore. But one thing that is a bit hectic is the space in the engine bay, it gives me a headache thinking about turbo set up. But a S/C setup is not necessarily any easier. I done my research and if my situation has changed then I would of purchased the greddy SC kit and muck around with it ( I love the exchange rate at the moment). But I'm not going to be in this country anytime in the near future so thats why my sportivo had to go. I still miss my car, but life goes on...

The SC Vs Turbo debate is so old. Everyone to their own needs really. lol No offense but my comment was on how negative peoples attitude was towards how this 'incomplete' machine should be even allowed on the road. With that much money to throw around I would believe this guy is far from finished with his car. I'm met another fellow sportivo owner at my workplace and he spent heaps of money on his car and believe or not he doesn't have an aftermarket intake and he hasn't even heard of TOCAU. Whether he spent his money properly or not is none of my concern and as most people would say "as long as the customer is happy we are happy as well". Now I've just realised that I have completely lost it and don't know what the hell I'm going on about...anyone know a good doctor?

Just going through all the post again, most of it sounds quite negative. I'm pretty sure everyone is concerned with the current setup of the car. At least its gives the sportivo crowd some hope that obtaining a turbo sportivo is possible. At the end of the day its his choice... If anyone has decently looked into slapping a turbo onto the 2zz, its quite a pain in the **** to do. So thumbs up to CES and the owner of the vehicle.

Seeing how that the ECU changes its fuel map and performance characteristic depending on the driver. How many runs does it require until we see the peak power figure become more consistent?

Ok I haven't done much further reading, but wouldn't switching your cams at a lower rpm point require you retune that rpm interval??

I've made it a personal rule that if I was to upgrade the sound system of a car then sound deadening is a must. Brings out the best of the front stage midbass!!! $300 splits + Sound deadening will completely own $600 splits if you just installed it alone. It makes that much of a difference that it was worth $220 + 3 hours + 20 cuts on my forearm. lol
