TSX motor swapped into rsx base DYNO
Saw this thread on clubrsx.com:
http://forums.clubrsx.com/showthread...&highlight=tsx
Here are his mods:
Stock internal TSX engine (no type-R cams)
Comptech RACE header (with custom motor mounts)
2.5 exaust with Greddy muffler (bolted)
shortram intake with K&N filter (mounted)
overbored TB
Hondata IMG gasket
STOCK Type-S manifold (not gasket matched) <-- last minute
K-Pro (partial tune)
Conservative timing, 90 octane mixed regular and premium...
VTC - confidential but very mild
AF reading tuned per RPM.. (changes for best result)
non vtec map not changed, HUGE POWER TO BE FOUND!
My comments:
THe thing that strikes me as most interesting is the 175 lbft or so to the wheels just off idle and all that without serious low end tuning. We'll have to wait and see the gains but I have a feeling an extra 15lbft of torque is going to be on tap for the tsx with just hondata and an intake!

Here's comments from the guy who did this, taken from HT.
I'm impressed by the way he's at the final Vtec stage at 4700 rpm, and pulling big time all the way to 7400.
The prototype manifold and fuel rails were not used in the dyno..
2.5 exaust mounted to greddy (not open header)
comptech race header
Custom motor mounts to allow header to clear firewall and subframe
AEM shortrame intake (actualy a shortram cut shorter to clear) piping about 14inch's long mounted with K&N filter
kpro (with a partial tune.... plenty of power to get (VTC was still low) and ignition was conservative...
type-s manifold (none ported or gasket matched
70mm tb, 65.5mm plate, 12 degree taper
hondata IMG gasket
TSX injectors
that's it...
basically a I/H/E with hondata
no tricks.. 90octane.
dynotjet numbers...
here's the video for the nonbeleivers... (video after dynotunning on highcam)
http://personal.nbnet.nb.ca/tuned/after.WMV
and another when nailing it in first... (this was prior to tunning, 190whp-160tq)
http://personal.nbnet.nb.ca/gbvautou/run2.WMV
the kpro was only partially tuned on the highcam to see the best AF value the k24 wanted. I can still advance the VTC another 10+ DEGREE's to get even more power topend.. the difference between these two lines are the VTC change i made, and trust me it was a small one, so the VTC makes huge power in this motor...
the low cam wasn't touched, just tuned for FUEL AF perfectly for part throttle under the mods i have... with tunning i'm certain i could more torque than 181...
if ever hondata releases something for you guys, get it.. the k24a2 is serously untuned ..

I'm a bit confused. This guy did a swap and put in a bone stock TSX engine. Added an intake, header, gasket, and pulled this dyno, or did he swap parts from a TSX and strap it to his RSX engine?

The guy took the TSX Longblock (K24A2) and slapped it in his RSX Chassis. It seems, judging by the videos, as though he ha retained his original RSX tranny.
Then he has added those other accessories like I/H/E.
Since he has his TSX engine in the RSX chassis, there's no such thing as DBW, VSA et al. Which means that he is running the engine with an RSX intake manifold and TB (though the TB has been overbored), but with TSX injectors, for greater fuel injection capacity, I assume.
This also means that he doesn't need the factory TSX ECU to run the engine. He can do it with a programmable RSX-S Hondata K-Pro.
So if you want an idea of what the TSX engine could do with basic mods, enhanced with a K-Pro, this dyno is revealling: A net gain of 45 WHP!!!
I know I am absolutely amazed by this.
Note also that we could use a RSX K-Pro in the TSX chassis, but that would mean no more VSA, and we'd have to dump all the DBW system and swap in a EuroR pedal-cable-throttle system.
Lots of work, and lots of sacrifices too.

To me, the VSA is something I would sacrifice for the extra power. My next question would be, does anyone know what is entailed in dropping the DBW system and adding a cable system. Are the parts interchangeable from the RSX to the TSX.
Last but not least, I guess the big deal w/ the guys tranny is that he has a stock 5-spd tranny versus the 6 spd offered in the Type S?

But if my understanding is correct, we can use Hondata now, providing the DBW system is not in the car. So why wait?

Are there any gearheads in here that knows what exactly it would take in order to remove the DBW and put in cable instead? Maybe a good import performance shop would know?

My guess is you would need to get a parts scheme on a Euro Accord 2.4 in Europe, and compare it with a TSX parts scheme for the pedal / cable / throttle body assembly.

Man.. all this anticipation. It works out for me though. No $$$ no so I can't get the ECU anyway. I'm sure I'll have a job by the time Hondata decides to come out with something.
Anyone know anything about MINE's ECU for the Euro Accord?

That's not bad for a K24 in an RSX, but it could definately do better... Remember my RSX #s?
Horsepower dyno:
Torque dyno:
Let me know if you need a towel.
This is what the equipment was at the time (on a K20)...
Injen CAI, ITR cams and intake manifold, Competition Clutch iron puck, Exedy racing flywheel, Phantom Grip LSD, Hondata IM gasket, Hondata Type-R flash (...K-PRO is hooked up, but not finished tuning yet), Spoon head gasket, GReddy evo (now bolted to the Toda header), ES motor mount inserts, J's racing (Mr. Alex) torque dampener, Mr. Alex fender braces, Revo short shifter with custom metal shifter bushings, KW level 3 14-way adjustable coilovers, Neuspeed X-brace, Spoon rear lower tie bar, Spoon front and rear strut braces, and I also have your mom sitting in the passenger seat for good luck
I agree that we could do the K-Pro in the car right now, provided we dispose of the DBW and VSA systems (...which I don't think are worth killing off for the time being), but it isn't coming any sooner after Acura decided to change the 05 RSX-S (calling it the K20Z1 with its ITR cams). With the market demand on hand for the RSX, Doug stated that the RSX unfortunately takes precedence over the TSX owners (we're way outnumbered, despite some peoples' thoughts).

There is definitely room for improvement. The guy hasn't tuned the low cam at all supposedly. Not withstanding that your top end is much stronger the fact that your tq curve is behind by 25-35lbft though the entire range means from a 5 mph he'd be able to pull.(assuming you were both using type-s or tsx trannies)
I think once hondata comes out it's going to make the tsx what everyone wanted in the first place. Even if 200whp is all most people will be able to get without major work that solid bump in toqure throughout will make the car even smoother than it already is.

If 200whp is possible with the Hondata/CAI combo, any idea what kind of torque improvements we might get?
Also, what 's the latest on the Hondata? Is it coming any time soon, and how much is it likely to cost?

I haven't been reading much about this. But how to do all the tuning without fucking up the ECU Nav and whatever other BS. I'd really like to just be able to tune a separate ECU. I dont wanna deal with cops or smog. I already had to sell my Euro R prelude because of that ish. However these numbers are getting me all excited 
I drive an 07 TSX
( god damn warranty to consider as well ) I wonder how far its covered
Shoulda just bought an 04 
.... USED
