Yeah, I've read that the problem was the engine would flood upon cranking whenever Hondata tried to run hi flow injectors. With 5 psi of boost the stock injectors (w/ the increased fuel pressure) start to hit max duty at around 7100 rpms or so. If we want to run higher boost there is the danger of going lean unless someone finds a solution that allows us to run higher flow injectors.

 

You could also run methanol injection for more fuel. Plus an octane boost AND lower charge temps. That's what I would do. Just make sure to keep the meth tank from going dry.

 

Um, did anyone take a close look at that Dazz motorsports TSX? They're running a full turbo kit on that car using this engine management system, which claims it works with DBW, so why wouldnt this work with the tsx?

heh, look at post # 37. I mentioned this

 

crazybaboon6000 and rza49311, the hks system works to an extent. yes it works with DBW however on the tsx you lose, ac, factory gauges, and traction control. so no only is the solution expensive but your basically building a race car then.

 

Thats why i was gonna go with the K20a2 head.. im trying to run past or up to 8k rpms... i just got the head just in case.. i might not use it but i might not run into another one on the east coast again, so i had to jump on it now. Nobody wanted to ship it from the west coast so.. I might port the TSX head instead and i should see nice gains from this

 

So what are you going to do w/ the K20a@ head? Will you get the harness or will you get run RSX ECU/K-PRO + TSX ECU???

Make sure you have someone to tune it for your professionally, have fun and tune safe. Remember to post back result, DYNO is a MUST.

 

Whats the latest with regards to making this work ? im looking / saving for the jtune reflash upgrade but this kpro great also

 

Im looking towards going to RS MotorSports. I emailed them and it seems like i'll be going there for the tune and install. Its gonna be awhile though.. i have to get the parts! Im gonna go RSX+TSX ecu with K-Pro. RSX ecu's are running really cheap.. i was just offered one for $200..

 

You want an RSX ECU that has K-Pro on it. Make sure that you can get the harness before you start buying parts though. Good luck man

Have you tried contacting the Hydra Nemesis guys again?

I emailed Hytech and they said they make one...

 

Also look into AEM's Fuel / Ignition Controller (F/IC):

This looks like it might be able to handle our injector problem:

 

^^ PrecyseStylez, you would be better off with KPro. It can do a lot more. I might look into the AEM for my setup though.

 

Nice find on the AEM

 

Make sure you get the RIGHT RSX ECU, which is 2002-2004. I remembered that the 2005-2006 RSX ECU can't use K-Pro, so beware.

 

Im aware.. but thanks for the heads up!

 

Oh obviously K-pro is the way to go. But who doesn't want a functioning dash. I know the fiance wouldn't bee too happy with it. And the FI/C controls quite a bit of functions on the car. Maybee a combination of the FI/C and a re-flash would be the ultimate solution found yet??

 

The route im taking will keep the dash functioning.

 

That sounds like it would be totally seamless and work great with the stock ECU and sensors. I'll bet you could overdrive the blower for a few more PSI without any issue with that, since the VTEC, VTC and timing tables are already rewritten for the supercharger. It might be the cheapest way to 20+ whp over what you have already.

I would look into methanol injection as well. Tons of people run it with some form of FI at higher levels of boost. Most use a 50/50 mix of water and methanol. Methanol has an octane rating of 116, which enables a lot of timing advance (or in your case since you can't control timing, just tons of detonation resistance). It is also an oxygenated fuel, so it needs less air in the charge to burn completely (stoich for methanol is about 6.5:1). This means that you can add even more fuel when you're squirting it, and still make power. Methanol vaporizes in the intake tract, so like nitrous it cools the charge due to the phase change. Most of the time, water is added to the mix because it has a higher specific heat capacity and can absorb more heat in the cylinder, thus preventing detonation a bit better. But in your case that wouldn't be a problem, and you could run straight meth just for the sake of extra fuel.

It might be too high maintenance for you though. You couldn't ever let the meth tank run dry or else you'd be running into danger. It is another option though. Here is the system I'm looking into:

Great find!

I'd love to use this in conjunction with a high-boost pulley to eek out closer to 8-9psi of boost. However, I wonder how necessary it'd be to utilize an intercooler/aftercooler at those levels...

 

8 psi peaks at 192 deg F. 12 psi peas at 233 deg F. For the M62's, There is no cooler for them yet. You would be better off using Nitrous as the cooling agent.

 

does that mean AEM FI/C?

 

Sorry for the ignorance, but how would you run Nitrous and a S/C at the same time? My understanding was that FI requires that you advance timing, while Nitrous requires you to retard timing...



(Oh, and nice avatar pic...Twin-Screw, ehh?)

 

"The cooling from the nitrous allows you to gain more HP than just what is provided by the juice alone (I gained almost 100hp from a 50 shot), the actual amount gained is a function of your boost level and the shot size, there is not a simple calculator so expect your results to vary" A dry shot in the intake tube such as this is ideal for cooling the IAT from a charger.

Problem is you need K-pro to run in properly

I will be fully testing the AEM FI/C shortly, But its features look promising to control our TSX ECU FUel, TIming, and Vtec control, Only downfall I see is no VTC control. Not ideal but could be fixed I would think.
"Since the F/IC works in conjunction with the factory ECU, late model-vehicles equipped with a CAN-BUS system retain functionality of climate controls, dash and other components on the network."


TSX536 I saw you asked about it for an AUTO I would highly doubt it.

 

Yeah those Eatons run hot once you step outside the tiny sweet spot of their efficiency map. It would be nice if they'd come out with a bolt-on high helix version of the '62 like they have for the 112 and 122 cubic inch blowers.

Personally I would rather run methanol/water injection for charge cooling rather than nitrous above 1 bar on the stock internals. Or just water alone. Cheaper, easier, and doesn't lead to possibly dangerous cylinder pressures from all the extra fuel you'd have to add to keep it from leaning out.

 

Well the Newer TVS chargers from Eaton will be out shortly from what I understand and that is a hybrid style Roots charger. I think it partially compresses in the Charger housing and in the manifold.

Nitrous as a cooling agent is a finiky thing, ideally a cooler, be it water-air or air-air for a supercharger would be an ideal way to cool the IAT.

 

I just purchased the RSX-S VTC...

 

UMM shouldn't go more than 45 on the TSX...the 50 from the RSX can be dangerous.

"Allowing the full 50 degrees movement leads to a greater risk of valve to piston contact should you accidentally mis-shift and over-rev."

 

I know that.. but its adjustable, am i correct? So i would be able to adjust it 45 degrees with kpro.

 

K-pro allows for adjustablility, although a mechanical stop is better than a electronic one. It really depends on your tuner Who do you plan to tune your setup? That makes a big difference, wether if be a conservative tune or an aggressive tune.

Yes it is more adjustable but with the long stroke the 2.4 I can't imagine that it is necessary.

 

Can't wait for your update. Have you locate a RSX ECU yet? If not click links below.

From what hondata and others say... more than 25 degrees is needed for a fully built race motor. but no more than 45 is needed nor recommended. So as long as im able to adjust it past 25 degrees and decrease it from 50 degrees, im good! i'd rather just buy a RSX-S VTC rather than find someone to manually adjust the TSX VTC... and plus i picked it up for 50 bucks..

 

$50 bucks? Awesome. You should be fine with the RSX-s VTC, Hytech has been running cams with this set-up for a couple of years now. No worries.

 

ask joe at lowcash if he can assemble one


locashracing.com

I bought an obd2 a to b conversion harness for my Euro R obd2 motor that was in my prelude.

 

Any updates on this project?

 

So far just purchased the RSX-S 50 degree VTC next will be ECU and then harness and last but not least K PRO.. i just have to take care of a few things first.. i'll keep you posted. Im gonna run the K-Pro/harnes/RSX ECU and TSX ECU to see if the car will run properly first before i start buying cams/springs/retainers/etc. If all fails i'll just run a K24/K20 frank in a civic bubble..

 

Sounds awesome man
atleast we see some progress and updates, can't wait for more.

i want to know how this is going

 

I've been on time out for awhile.. trying to pick up parts here and there. i'll post a new thread with pics at a later date. i wont let you guys down!

 

bump!

what parts do you have now???
