Hello fellow members,

I would like to formally introduce ourselves at Ultimate Racing to Honda-Acura.net. We recently acquired a silver 2002 S2000 which is our third project car. Currently, we offer cold air intakes and a 2.5" cat back stainless steel exhaust system which includes a high flow catalytic converter.

Our turbo kit is approximately 90% completed and should be available by mid December. All the hardware is complete and the tuning process is almost finalized. To view one of our protype cars, please visit our temporary picture gallery at http://www.picturetrail.com/ by logging onto "ultimate-racing".

Dyno results of our S2000 turbo car can be viewed in the 'dyno chart' album from picture trail as well. In addition, we will send our turbo equipped car to be emission tested in Toronto, Canada. Please note, once the test is complete, the results are for Canada only since some states may have different emission requirements. The kit will be completely bolt-on and supplied with detailed step by step instructions (including illustrations) for competent do-it-yourselfers. In addition, the installation manual will be available on our revised website (the updated website will be online in the next couple of weeks) at http://www.ultimate-racing.com/

Here is what our turbo kit will include:

-Custom heavy gauge mild steel exhaust manifold with heat shield
-HKS external wastegate
-Garrett TO4E turbocharger
-Custom 2.5" stainless steel (SS) downpipe
-Large front mount intercooler kit with 2.5" polished SS piping
-Custom 3" polished SS air intake pipe with high performance K&N filter
-HKS Super Sequential Valve (SSQV) with mounting flange
-High flowing 440cc injectors
-Pre-programmed Greddy E-Manage piggy-back computer system
-Oil filter re-location kit

NOTE: No other factory parts will have to be removed or modified other than what is replaced by the kit.

The price for this kit will be approximately $5500 usd, or $8800 cdn. Approximate pricing for our 2.5" SS cat back exhaust system (twin mufflers) is $850 usd or $1350 cdn and a bolt-on SS high flow catalytic converter is $240 usd or $375 cdn. Once the kit is completed, we will release the final pricing schedule for all parts. Custom applications (ie. 3" exhaust, single tipped exhaust, etc) are available upon request including the turbo kit.

If you have any questions or inquiries, please feel free to contact us at sales@ultimate-racing.com or visit our soon to be revised website which should be completed within the next two weeks at www.ultimate-racing.com

We look forward to getting to know you all better.

 

how many lbs of boost is the kit running it?

 

Hello Captain,

Our turbo kit runs 6.5-7.2psi.

Thank you,

 

Hello fellow member.

 

Sounds interesting...it'll be nice to see how it stacks up against Speedcraft's kit. Have you posted this on other boards?

Hello everyone,

Thank you for the welcoming. In comparing our turbo kit to Speedcraft's, it is in my opinion that they should produce more peak hp but the midrange might not be as stout. Both kits are good and I will explain our kit in more detail.

Where the S2000 needs the greatest boost is below VTEC engagement. Our kit achieves not only adding generous hp to the top end, but greatly improves midrange power. This is especially important powering out of corners and switchbacks on the track, and for street applications.

Our Ultimate Racing turbo kit includes a tuned piggy-back computer (E-Manage) utilizing the best of both worlds. The drivability and refinement of the stock computer and the adjustablilty of fine tuning specific paramters to produce safe, reliable power with excellent driveability.

This computer add-on seemlessly communicates with the stock computer's sensors such as the throttle position sensor (TPS), MAP sensor, and other associated sensors that are imperative to the cars driveability characteristics.

The E-Manage modifies the stock ECU's pulse width signal which determines the duration (in ms) the injector remains open. In various situations (on and off boost, idle, etc.) the laptop tuned E-Manage will recognize and change the injector pulse width accordingly. Behaviour of part throttle, start-up, on / off boost retains stock drivability.

Larger injectors are used correctly to fend off fuel cut (when the maximum fuel delivery is achieved through the injectors) and ensure reliability, driveability, and longevity. Other systems that use just a fuel pressure riser (ie. Speedcraft) may increase the fuel pressures too high for the stock injectors. This is a simplistic method to add more fuel at the cost of the longevity of the injectors and driveability.

By using a fuel pressure riser (FPR) that normally increases the fuel pressure by a rate of 10:1 or 12:1 (10 or 12psi of fuel to 1psi of boost pressure), injector stress may occur. For example, at 6psi, the FPR (12:1) will add 72psi of fuel pressure to the stock rail pressure! Most factory injectors including the S2000, are not meant to see fuel pressures of over 100psi. This is why Ultimate Racing uses the multitude of tuning parameters of the piggy-back fuel computer and larger injectors. In addition, timing advance, low and high throttle loads can be taken into account unlike the simple FPR.

Thank you for your inquiries.

 

Current dyno numbers with 8 psi: 320 HP with 212 torque

 

320 WHP??? 212 Torque? All I have to say is wow.

What compression are you running at? I'm assuming the Ultimate Turbo Kit is meant to be used at stock compression

lol...soon enough....

That is from Speedcraft website. It also on pump gas and with headgasket.
