hey everyone, i am new to the boards. my friend told me to get on the forums. i just got my car for 6 months. a 2004 black s2000. i been taking care of this thing from the start, right now it has 1956 miles to be exact. i feel like the car needs more power. so i tryed searching on the boards and tryed to find some good turbo kits, but surprisingly, since i am new to this thing, i have no idea how to really work this, but that's ok. i was planning on getting either the rev-hard kit or the ultimate racing kit. they both are t3/t4 turbo, i plan on dishing in a little money to make them ball bearing. do you think it's needed? i mean ball bearings spool up faster from what i have heard. or do ya think i shoudl go with another turbo kit. i want a kit that is well built and puts out nice numbers. thanks

 

Hi Klutch,

I would just be prepared if you do a turbo kit to get the necessary tuning done. Also, from what I've read on the forums, getting the turbo kits working 100% can cost a lot more than the initial price of the kit itself, it is not completely bolt-on like a supercharger.

Also, from recently doing a supercharger myself, I can tell you that you will need to upgrade other components of your car such as clutch, differential housing, etc, and I would strongly consider getting an AEM EMS ecu to control all aspects of tuning, and run your car safely.

But I'll let a few turbo guys chime in on what they've gone through with their kits.

 

So there are multiple options if what you are looking for is the car to feel more powerful. One of the best bangs for the buck is gears, it'll give you the feeling of a more powerful engine without the additional stress of FI. It's also a pretty good bang for the buck.

If you really feel you want a turbo, really do you homework. Don't let this be a rash/quick decision or you may be buying a new engine. There is a alot of good information available by searching the site. So far the SC kits have shown to be fairly good bolt on kits, no turbo kit has consitently shown to be a safe bolt on kit.

Turbos on the S are not for the faint of heart. I'm only considering one now(the Elda kit), because it is planned to be both CARB legal, and I happen to trust in the engineering of the designers, Bell Engineering. However the kit isn't out yet and we'll see the results when it is.

 

thanks for ya's reply. yes i will upgrade the drivtrain and such when i do go f.i. even tho i am leaning towards the turbo's, but i will open up to super charger's also becasue i want power. they both give power, but which is safer? from what i have read and heard and magazines, most of the time the super charger is the better bet. it might not give out enough power as a turbo charger but super charger are more reliable. i heard vrotech and comtech are the best super chargers out so far for the s2000. i also heard they both now come with a aftercooler and have upgradable pully's meaning more boost. i'v read alot about superchargers on this board. turbo's are hard to come by. which get's me thinking. should i switch from a turbo to a super charger? i'll spend a lot less money on the super charger because i wouldnt really need any tuning. you guys got me thinking.....

 

opps double post

 

any form of fi is going to be hard on a stock engine. most of the turbo s2000 that have allot of problems are either pushing a pretty good amount of boost on a stock engine or have a high hp s2k 400+. A sc is usually pushing around 300hp. i have heard a few bad things about the centrifugal sc such as they vibrate your engine to death after a while (correct me if im wrong). if you are only shooting for 300-350whp then a properly built turbo kit would be extremely reliable. there are very few bolt on turbo kits im impressed with in my opinion you would be much better off getting a custom kit or if you want geoff at full race makes the best kit i have seen for the s2000. honestly 300-350 hp would be good for low 12's 1/4 if thats your thing.

by the way i have seen both the rev hard and UR kit on cars around here they are IMO not worth the 5 grand for there cast iron manifold crap. and the maps that you get with those kits are completely worthless

I have the Ultimate-Racing Turbo kit as well as a lot of other things. I've been driving with it for about a year now and I can tell you couple of things to watch out.

1. Make sure you have a strong gasket. If your turbo kit does not come with one GET ONE!! I've seen too many people blow motors because they ran boost with factory gaskets.

2. Watch for Boost creeps. It helps if you run higher cc injectors expecially when you try to go straight pipe and drop the cat.

3. DON'T USE PIGGY-BACK SYSTEMS!!! GET AEM EMS!! piggy-back system only alters the original fuel meansures from the ECU and tricks the computer so you'll feel jerks and bad responses from the throttle. Also piggy-back system cannot be nearly as accurate as a SMU (Stand-Alone Management: AEM EMS) as far as tuning so you'll often throw check engine light due to running rich (hopefully not lean). Also temperature will make it throw a check engine light.

4. If your gonna bolt a turbo kit on a factory motor DO NOT OVER-REV. Well...this is true with any engine in any state but you'll feel more pain (as in more $$$ later you'll have to spend) since the factory motor will blow easily. Usually the piston will hit the valves and bend it destroying both internal block and the head. Which of course = to $$$$

Tuner

 

this is very interesting. i saw a video of a comptech sc'ed s2k vs a supra tt with many upgrades and the car was i think around 600hp or more and the s2k jumped on it for about 7 seconds before the supra could catch up and past and than it was really over from there. a custom turbo kit will cost more correct? it's a option but i know for a fact it'll run better and more reliable than most built kits.

 

i say you wait a little longer, i've noticed a lot more turbo kits coming out now for the s2k, probably mainly cause they've started to work on the s2k more and they know the motor better now then they did before. i'm sure more companies will start producing turbo kits for the s2k... i also agree with nxt774 about the maps that come with those two turbos are worthless. once you get the kit you're gonna want to tune it asap with an AEM EMS and nothing less then an AEM EMS...

 

supra are great in the end from the video you saw.
a custom kit will cost more but if you get a good builder it will be the best in the end.
turbo kit
speedcraft(over now)
ultimate racing
inlinepro www.inlinepro.com.

what you need are good parts that won't turn like shit in the end.
don't get the ultimate racing unless you feel like doing just that.
get it custom made. and get a aem ems

yes a supercharger is more reliable but as i read most people are having troubles with superchargers more then turbos.

ohcourse there are less turbocharged s2000's then the supercharged ones. but not that many probles from the turbo unless you totally don't know how to maintain it.
if you have any other questions just write it as

p.s if you want to explain your q's then write them here so it's easier for me to read.!


edit
custom turbokit list
intake can't use stock ones!!!
turbo exhaust manifold
turbo or turbo's
wastegate
BOV
pipeing
downpipe
intercooler
dump tube
FMU
fuel pump
map defensor
oil relocation kit
stronger gaskets
bigger injectors
aem ems
boost controller
fuel controller(if aem doesn't do it)
boost gauge
a/f ratio gauge
testpipe. also needed 02 simulator
3inch single out exhaust( i don't think there is a need for two)
clutch with lightweight flywheel
fuel pressure regulator

edit again: most people's tubo motor go kaboom because they want more boost. you should stay in the 7-8 range if you have a stock motor
