A while back when scionspeed first introduced the stage three, i believe they only ran 12.09 once. There was a forum way back about it but i don't know if they have ran that time or better since then. ZPI has the fastest tC in the sense they have proven that it is. Not just one run. When you get technical there are litterally hundreds of things that can shave off .1's or add on to your time depending if everything runs perfect or not..Or as close to perfect as possible. Scion speed is absolute crap anyway. Theres one forum about how scionspeed literally screwed his motor up..bad. If im not mistaken, ZPI had offered to help fix the issues although it wasn't their turbo kit. Scion Speed, so i've heard, has had tons of problems with what they offer. ZPI actually put thought into their design. You are not only buying a kit thats going to produce a good amount of power for its stages, but you are also buying a dependable and quite affordable kit(s).

As for Jotech. Its an alright tC, i personally don't like some things he did in the build process. However, it was built for show. Not to be daily driven or a track monster.

While I admire greatly the efforts and accomplishments ZPI and a few others that made, "fastest tC' to me will always be real world, driven on the streets, canyons, pump gas, reliable, corners on rails, stops on a dime, beats cars supposedely far quicker, etc.... and can last more than a few qtr mile runs before needing a complete rebuild

Don't get me wrong at all, Titan=COOL, ZPI=+COOL, Dezod+COOL, Scoinspeed+????

I just like corners better and plan to have the "fastest" cornering street driven tC there is, period. We are investing a huge amount of our time and a fair amount of money into doing this, it will take power of course, why it will be boosted

Trying to beat EVO, STI and M3s in SM class, SCCA, autocross is quite a big undertaking, one heck of a challenge, why it is so fun;)

We will most likely be running one of the turbo systems gettintg so much attention here, just not ready to spill the beans but when the time comes....

I agree 100% with you. Which is why i autocross vs. 1/4 mile run most of the time. Its more challenging, and its much more fun in my opinion. You don't only challenge your cars ability, but you challenge your own to handle the car and really become one with the track in a state of mind. However, ZPI in terms of general fast, is the winner. I thought they did drive their tC on the street too? I could be wrong, but i thought they did. *Shrug* If they don't thats cool. Putting aside from company tC's, i imagine forum wise would be those who have the stage 2 ZPI kits since the stage three isn't out yet...Or so i last heard.

As for trying to beat STI's on autocross. I've came close once in my box. The only reason i did is because the guy messed up twice on two corners and lost controll. But of course, straight away he absolutely killed it and regained his time to a degree once he got back into the corners. I have found that STI drivers either aren't very good at all at autocross, or the drivers are absolutely amazing. I haven't seen an EVO yet on autocross..Well not in person. M3's ive seen a few. And all of them had amazing times. I think people should start looking more into autocross and road tracks if they want to build a overall fast car. Straight line anyone can do.

auto x requires alot of skill but not every one can do a 1/4 run well not good any ways just like every one can auto x but not good


if you look at my times with my few mods hell the exhaust wasnt even one of them till saterday and i hit a15.2 in the 1/4 it takes skill just like auto x and not every on has the skill to shift that quick and launch that well just like not every one has the skill to take turns like you and rick

 

ZPI's Track run was not a streetable car in any state. Unless they allow you to run open downpipes in kentucky /shrug i haven't lived there in years.

As for Scionspeeds suspension set up and LSD then in auto x i'm pretty sure scionspeed has the faster tC. The LSD in thier tC is a phantom grip, wich i've heard numerous arguments on how the phantom grip isn't a "real LSD".

Scionspeed's "Light weight interior" advantage. Racing seats, TWM short throw shifter, MOMO steering wheel, MOMO Pedals, Titanium floor grids. You fail to mention the complete audio system wich kinda balances out the entire fact that the only real weight reduction scionspeed had was the racing seats

Scionspeed had a larger turbo than ZPI. Yes they did, but they didn't use the huge t60 from their stage 3 kit in that run. They used a t3/4 hybrid turbocharger. The same type of turbo charger that dezod is using in his kit. ZPI were the ones who chose the 16g turbo for the tC. As far as I know ZPI is the only ones using the 16g for thier kit. Greddy is using an 18g, turbonetics is using the t3/4 hybrid as well as dezod.Yes scionpseed ran more boost, but the scionspeed did not run at full boost. Thier tC was fine until 19 psi when the boost started to lift the head. Also the scionspeed tC's times are old, From articles I've read they are working on internals and head bolts.

Scionspeed is pretty much dead. You can not even order thier turbo kits online anymore from my understanding. But, the fact of the matter is Scionspeed was the 1st in the 12s. and currently have the fastest 1/4 time. You people need to put your emotions aside and just give credit where credit is due.

And as for you turbocustomz. Lets say you did run against the scionspeed tC and they ran thier best of 12.09..

And as for you turbocustomz. Lets say you did run against the scionspeed tC and they ran thier best of 12.09, and you did the zpi best of 12.12. Are you the guy who takes his loss. or are you the guy that gets out of the car and demands "2 out of 3"? I know where I come from a loss is a loss. and the guy that screams 2 out of 3 gets laughed at.

 

Blah blah blah. The FACT of the matter is, scion speed does not have the fastest tC. In fact, it doesnt even run anymore (last time I spoke with them). They would need to run their fastest time of 12.09 and they would still lose. You are missing my point entirely because there are tC's that have run faster. ZPI's car went 12.12 with a simple 14psi. You dont think that a car with methenol, nitrous and more boost couldn't hand that 12.09 to them? Both of those runs are old, both of those setups are old, and this arguement is old. Scion Speed is a bunch of half ___ home grown wanna be's that threw a half ___ turbo kit on a couple of cars, messed them up and is now a joke among the scion community. Thanks, and have a nice day.

Well i don't have any personal emotions towards scionspeed because they personally have done nothing for me nor against me. The only reason why i do not give them credit is because they only ran once at 12.09. (from what i've read and understand) A one time run doesn't give them the "fastest" title. Everyone can run a one time deal where they blow their average times out the window. Its luck. I'm not saying scionspeed was lucky, but for them to only run that low 12 once makes me wonder if it was. Again, i don't know if they have ran again at a time very close to that. But, if they have, i haven't heard anything about it and haven't seen any newer post about it so my thinking is no.

Not to mention, when you talk about street. Scionspeed might have the fastest set up, but its not going to last long from what i hear and from what people have posted about things going wrong. ZPI has their act together, and have run numerous times proving its not a one hit wonder with fast times. Thats why i give ZPI the winner for 1/4. If you don't agree with that, thats fine. Thats just how i view it.

You are correct. But, when you look at everything envolved with 1/4 vs. autox. Autox is more envolved. (of course) So thats what i was getting at. When it comes to driver skill, 1/4 anyone can do it with some experience and learning launch and shift points within the RPM. With autox, launches do matter, but how you corner, when you shift in the straight aways, when you slow down and pick up again around corners and before. All of that goes into play. Thats what i meant, but i do know not everyone can do either. In fact, not many can do it well when they first start doing tracks anyway. Experience pays off! heh.

I agree, 1/4 mile does take some skill, I can fairly good at autocross but there are better drivers out there no doubt. I have to prepare a care exceptionally well and then do the best I can as a driver who is still learning FWD, hard to break decades of RWD habits.

I have great reaction times at a drag race tree yet launch poorly all the time, lol! Then again I have only drag raced a few times in my life and with road race tires it is rather hard to do it right, I have been faster on street tires, really.

The last time I ran some drags .500 was considered a perfect reaction time the way their timing system operated. I did a .508, .503, .501 and a .500 back to back yet launched terribly each time, lol!

They had a trophy for best reaction time and a guy with a really sweet Pantera kept laying down his slips, then I would, then he would, really funny except I kind of felt bad for winning, his best was a .502 so I did not show my .500 just to be nice about it. In fact I had no intentions of picking up a trophy, my kids bugged me into doing it.

Anyway, all forms of motor sports requires skill and I appreciate the skill of good divers, riders, etc, even lawn more racers, really

Once we get our tC fully dialed in I am going to put a pro level driver with experience in really quick FWD cars in and find out just how fast our car is and then use his (or her as I know some women that can shame all of us here) feedback to make it better yet;)
