woot. lots of opinions in this thread.

being builder, owner, driver: TC>SC(centr)>NA

as for the upgraded SOS kits and the like, the Centr SC on our cars is gay with a capital Clay Aiken. The powerband of the SC is like that of a dying GT40 with a 9lb wastegate spring. no low end pull thats worth noting whatsoever unless you run something ridiculous like a 15-18 psi pulley and risk pwning the SC alltogether. its basically like driving a V6 equipped S2000. plain and simple.

now, with a turbo setup, you have a wide range of power curves you can acquire by simply spec-ing the turbo and housing combos. you can literally get everything you want in a powerband and not "disrupt the driving fun" of the S2000 and have more usable power thn the SC. the smaller the turbo(compressor or turbine housing) the more it will pull like and stock-mild STI or Evo. the larger the turbo/turbine housing, the more it behaves like a t88 supra. Its all relevant and perspective-based off of a end-means goal.

having had all sorts of variations myself and working for a company that builds ONLY scca SPO and race cars as well as running my own small business, I can offer this opinion of my own:

the Centr SC on the S2000 is a waste at any power level. yes, you have less to worry about in terms of bolts coming loose, welds cracking, etc. BUT, its the price you pay(include the pun if you must) for that setup with its lower power and weak onset of said power. Get an appropriate turbo combo for your goals and driving wishes, and you will be much much better off. and if maintenance worries you, just stay NA and have a blessed day.

 

Yep. I prefer Road coursing and mountain driving with an SC. I don’t like the power delivery of a Turbo. If I had a hp addiction and wanted to try and be the fastest thing on the highway, then a Turbo would better fit the bill I guess. There is much more to owning and driving a s2000 then what getting into the turbo game is about though. You can turbo anything and make it fast, but that doesn’t make it a great car to drive which still stays integral to what it is. A SC is the best compromise if that’s what your going for and you simply cant argue that. It always comes down to what it is your trying to retain and achieve, both.

 

I think part of the reason we don't see s owners going from turbo to sc is because they are probably going for a huge amount of power without regards to lag/spool/daily drivability whereas others go from sc to turbo because they had those things in mind but did not get the gains they were looking for? I don't think it applies to all but most.

I'll be the first to say that my S won't be my daily once I'm done with school. My job will depend a lot of driving around the state of FL so either way I want something good on gas. The reason why I went against a few of you in the beginning about a S/C is because I've had both and can't wait to with a T/C on this car.

You have these four members that have switched over to T/C and don't regret it. Not to speak for you guys but I spoke to team and torque about keeping my kit and getting the most out of it. They're both the reason why I'll be selling the kit once I'm done with school. For me I want a car that I can take to the the strip maybe once every six months and do some highway runs once in a blue moon.

 

^really? because with equal max pressures and appropriate components, at 3,000 rpms +, the turbo will be beyond the SC in boost.

please dont post crap.

 

I'd imagine he is talking about response. No question the sc gives much better throttle response but of course the turbo will make more power at any rpm once spooled.
Once at high rpms the sc is great. Punch it at 6-7-8k etc it is instant power with zero lag or delay or anything. Turbo does have to spool so doesn't give the same "instant power" feel. Once spooled of course it shoots you forward and puts you back in your seat much more.


Everyone knows the turbo setups are almost always more powerful and much broader powerband. No one is questioning that. However it seems some turbo guys can grasp how the sc does have much better throttle response.

 

Kinda funny. You can add me to that list. However I would love to buy a second s2k and put a 1200 blower on e85 and 20psi with a fmic. I want to road race lol.

 

even still, with a 6k hit and a 11 psi pulley, you'll see like 8 psi until you get to 8 or 9k, and then for a split second you will get your full 11, while the turbo was in that full 11 2,500 rpms ago. so in terms of full power "response", the SC sucks because for 1: it only makes full boost for like a second before you shift and 2: it takes 8-9,000 rpms to get there.

so, while you have the quick response, its a false/weak response because you dont get full boost right away, and the turbo lag you speak of wont take 3k rpms to recoup the full 11 psi. it will take like 1/2 a second and a couple hundred rpm.

 

Yeah I completely agree about that. A sc with a waste gate seems to be able to get somewhat similar results as turbo. Not quite as broad but much meatier in the middle than a normal centri. I plan to do that over the winter which should be nice.


I'm sure highway pulls and all are much more fun with the turbo. I just love the mountain driving and zipping around with the blower. Turbo would give too much of a power potential where I would turn my car into a monster I would never be able to drive lol.
