Hi everyone. My name is Chris and I am about to purchase my first S2000. I have been putting custom turbo kits on import cars for about 3 years now and I would like to put together a kit for the S2K when I get it. The car is a lot of fun to drive, but could use some more power, especially down low. I know a lot of people agree with me there. From looking around it seems like the cheapest turbo kit you can buy is from revhard for about $4000. I’m wondering how many people out there would like to go turbo and not have to spend that much for a complete kit. I can put together a complete bolt on kit and sell them for $3000. The kit would include:
Turbo
RevHard manifold
RFL blow off valve
Tial style 35mm wastegate with 6 psi spring
Downpipe w/ flex pipe
Front mount intercooler
2.5 inch Intercooler piping, Custom bent to fit the S2000, flange welded on for BOV.
Oil feed and return lines
Oil filter relocation kit
12:1 FMU
Walbro in tank fuel pump
Missing link map sensor
All couplers, fittings, clamps… (everything needed to bolt on and run)

I have a few questions:
1. Would you be interested in this kit for $3000
2. Would you prefer a t3/t4 .70 A/R exhaust .50 compressor with v-band flange and 3inch
downpipe or a t3 .48 A/R exhaust .42 compressor with 4 bolt flange and 2.5 inch downpipe? (I prefer the t3 for quicker spool up, this would be better if you plan to just run this kit the way it is. The T3/t4 is really only needed if you plan to get bigger injectors, engine management and tuning for big HP. You can still put up big numbers with the t3, but obviously they will be bigger with a bigger turbo. Whatever more people are interested in is what I will use in the kit.)
3. Would you prefer to pay more (like $3300-$3500) for name brand parts like a real tial wastegate? (I’ve been using these no name parts for years with no problems. They are the same thing just without the name, but some people feel better having the name.)
4. Any other input you have that I forgot to ask about?

 

I think we would like to see your R&D before anyone would just buy a $3000 turbo kit....Nothing against you personally but I would spend the extra money for a kit that was developed based on R&D

I will be installing one of the kits on my personal, daily driven S2k, before I actually start selling kits. That way I know everything works well. Also, I will be getting it dyno'd with a wideband to see how its running and what kind of power it is putting out.

 

Needs less FMU and more AEM EMS. I highly recommend you dont use a FMU, its such an aweful way to do fuel management.

Also about the turbo, i would never go with just a T3 turbo - it would be way to small. S2000s will spool a very large turbo very easily. The smallest turbo i would go with on our motors would be a gt30r or maybe a 50trim t3/t4.

There are lots of 400+whp stock motor s200s running around on pump gas and low boots (12psi). The f20 motor responds amazingly to a little boost!!

The reason for the FMU is to keep the kit affordable. I will sell the kit without the FMU to people who want to add there own fuel managment like AEM EMS. Also as far as the turbo, I'm almost positive it will be the t3/t4.
1 more question for people, Do you care about keeping it emissions legal? I can have the downpipe made with the wastegate dump tube routed into the downpipe (more money) or just leave the dump tube going straight down.

To make it emissions legal in California you need alot more then just a dumppipe - it has to be carb approved. In other states, like say Colorado, as long as it passes the sniffer its all good.

s2k has many turbo kits out their already, and many that are in development...

im interested in what your going to accomplish, im staying n/a, but im always into turbo information

Agree here. My s2k is going to stay N/A. But my civic makes almost twice the wheel hp as my s2k...on a smaller engine (1.6litres). Yay for turbo fun!

Id love to turbo my s2000, but im just not up for having two (broke most of the time) car projects.

Someone is ahead of you. He welded his own manifold and downpipe, uses a GT30R with a GT35R as an option, includes an AEM EMS with a pump gas map and a C16 map. I'd have to agree with the rest of the folks. I had a T3 on a D16Y6 and even that spooled quick. FMU was used on that car also. This is no longer simple OBD0/OBD1 overrides, you're working with a real motor now.

 

I think the kit you are talking about it way more than $3000. I'm not trying to make the best turbo kit for the s2k, I'm trying to make an affordable one. Basically this will be a cheaper alternative to the Revhard kit. I know it won't pass california emissions, but it should pass in most other states. I'm getting the feeling that most people who go turbo are not using their s2k for daily driving and are looking for big power. Do you think that is true? I'm using mine as my daily driver and just want a little more out of it, but I want to keep it safe and reliable.

 

Someone already said on this board:

"Cheap" and "S2000" doesn't belong in the same sentence.

i agree, doesn't go hand and hand...

People who have enough money to use an S2000 for track purpose only would lean towards the higher end set ups. I know my daily driver is staying N/A, but boost is imminent for my track car. I haven't seen anyone successfully attempt "cheap, safe AND reliable", but if you do, more power to you.
