Boosted or Blown???

[REV29k]

Hello everyone. I drive a 2000 S2K. It has about 45,000m on it. Babied since it had 20,000. Unfortunately the header, cold intake, and exhaust dont do to much for this car. I have heard two different stories as to whether I should boost or supercharge my inline4. Once i pay off the car(2 years), I want to eventually build the internals. Should i buy supercharger and upgrade it later? Or should I boost it now, and go from there? Hey thanks, your thoughts would be helpful and cost effictive for me. :help:

Personally I like to be blown lol. I would definatley say turbo, way more benefits, plus imagine the sound an s2k would make with a gt35r or something externally gated!! wow!!

Depends on how fast you want to go. The turbo has the most potential but will also cost you the most up front and in the long run.

If you have a lot of experience working with cars and have a lot of tools and free time and a lot of extra money then go with the turbo, lol.

A supercharger is simple which means it is probably also more reliable than going with a turbo setup.

Up the compression and go full n/a tuning. :cool:

Problem with that is having to run race gas all the time can get a bit pricey, lol.

It's always money, money, money with you people. :roll:

you can run ITBs and still use 93 octane so long as you know how to tune the car :thumbup:

mmmmmmmmmm ITBs :drool:


anyway, when my girl gets get S2K at the end of the year we're going to throw bolts ons on the car and then a vortech blower kit :supz: you already have the intake, exhaust, and header.....don't waste that money buy getting a turbo kit.....with the supercharger you can keep ALL of those parts on the car :wink:

how about neither...

just drive the car and use it to its potential...

turbo sucks for s2000 because the only people that can tune the car are in MD, and most people are not familure with AEM EMS and s2000 tuning...Jeff Evans can do it, but hes got a long wait...

SC is a nice mod. Vortec will make more power, but you have to tap into the oil pan...Comptech is a direct bolt on...

SC is way more reliable than a turbo, but it makes all its power after 6k untill redline...at least with a turbo you can pick and choose...

but with 11:1 compression you dont want a turbo. youl only be able to run 8psi safely. you need to lower the compression, and most kits cheap out and use a 3mm head gasket...

if you want turbo build the motor from scratch and run 9:1 or even 10:1 compression. but good luck, not many companied make low compression pistons off the shelf for an s2000...

ITB's is a bling mod...the gains are so crappy its pathetic on a BPU motor...

the only way ITB's would be a good mod is if he ran 12:1 or 13:1 compression on a built N/A motor with alot of head work...

ITB's also work well on the 2.5 liter stroker kits for the s2000...

i've seen dyno charts with s2Ks running ITBs and they made some nice gains throught their powerband with the installation of ITBs and tuning......a fully prepped N/A car is just like a turbo car in that respect......with cr ap tuning the car isn't going to sing to its fullest potential

[2point4DSM]

I know several people that bolted on ITBs over the years or different cars. It has never made a cost effective difference. And there is no way N/A tuning is going to beat a FI setup unless you can drop two N/A motors in there.

K24 bottom end, K20a2 head properly massaged, cams, ITBs, header, K-Pro=340whp, 295wtq. Put that in an EG and there is a potent combo anywhere.
I have tuned a couple of EGs with stock K20a2s in them to a little over 200whp with K-Pro. Those are very quick cars. The K series is the NA equalizer.

+1 for jeff evans. he is a guru.

Ultimate Racing turbo kit nuff said

[StreetEG]

you already have forged internals, so the only mod to do is headgasket...there are plenty of people making a ton of power stock block...reliably....theres a vid of the full race kit making about 450 at 14psi...

[REV29k]

hey again did some research. im going with a turbo set up. one mod i am looking to get for sure is the headgasket. Problem is i cant find a dealer that produces a quality gasket to lower stock compression. any solutions? again thanks for tha input.

Just to give you another opinion, mite see something you like or dont.
I say turbo but im biased, never dealt with s/c.
Good luck

rather than trying to lower the compression ratio by simply installing a head gasket....you should do it the proper way and install a nice set of forged pistons w/a lower compression ratio.

trying to lower the compression ratio of an engine that has a CR of 11:1 by installing a new HG will lead to a nice big pile of JUNK PARTS :thumbup:

i'm a firm believer of "do it right the first time or don't do it at all"

There are only two reasons to do ITB's. One, sharpen the throttle response and most importantly, two, THE NOISE! That's my only beef with FI, it ruins the induction noise of the engine.

I'd go ITB's and ride everywhere on a way of thunder. :)
