Impulse05

I have an '05 TSX and for a while I have been looking at the Comptech SC available for it. Everywhere I go people tell me turbo is more conventional for a Japanese car and will work/run better. I know as well as many other TSX owners that the car could use more low-end power and having that constant boost from the SC could be awesome but its 50HP at the wheels on a stock engine. If I change the engines parts [basically beef it up] would I be able to get more power out of the comptech SC? On the side of a turbo, they have the ability to give more of a boost than the SC but its a shot of boost not constant. And of course who doesn't like to hear the sound of a blow-off valve, its spine tingling If anyone has or has seen the Comptech SC in action or just knows which is a better choice the SC or the turbo I would greatly appreciate some feedback, Thank You!

I'm not sure where you plan on getting your turbo unless you plan on running RSX K-Pro with no gauges, cruise control, etc, etc... I would do a little research on these forums if I were you.

Impulse05

there are tons of turbos i can get im not so much worried about getting a turbo as i am getting it tuned and the over all performance im going to get out of it.

clee109

Yes there are alot of turbos out there but none work with the TSX because of DBW, the only way to run a turbo is with a Kpro, RSX ecu, and the TSX ecu running at the same time and I haven't seen it done with my own eyes.

Comptech has worked with Hondata to build a supercharger solution complete with an ECU reflash for the TSX, so for now your only option is the CT supercharger for FI on the TSX

Go with the SC. There is guy on here who just crushed the fuel pump regulator more (you have to do that anyway with the SC install) and put on a bigger pulley and got some impressive horsepower numbers. comptech has done all the hard work for you, with a turbo you have to do that work and there is no engine management. try searching for the thread.

jmathew34

try both at the same time

Impulse05

haha genious!! ill super charge a turbo to make an ultra super turbo charger! lol :P that would be nuts if there was a way to do both

mdkxtreme

im sorry if this is a little off topic, but i think its better to post it here than make a new thread. whats the difference between a supercharger and a turbo? which has more gains on hp and torque? i guess this is just a little food for thought for me

your only real option is S/C
and if you hae an auto, forget it unless you want to swap ecus with 04

DAYTA

Ummm...there IS a way to use both - it's called a twincharger.

The main advantage with a twincharger is that one form of induction negates the other's weakness. In other words, the supercharger provides boost in the lower RPMs when the turbo is still spooling up, and in turn the turbocharger provides boost in the upper RPMs without the parasitic loss that is associated with a supercharger.


Back to the original question, there is NO turbo currently that will function properly on a TSX without the loss of gauges and other amenities (HVAC, VSA, etc). The only reasonable option available to us right now is the CT Supercharger. However, since you have a 2005, is it AT or MT? If it's AT, the only way you can run a CT supercharger is to do an ECU swap with a 2004.

ThirdLane

Yeah there are many turbos out there. If you T/C your TSX, you won't have any engine management solution that will retain the guages, climate control, VSA, Cruise, etc. Plus you're looking at a lot of fab work for the manifold. CT supercharger is the only way to go

mdkxtreme

why is everyone ignoring me....

LukeaTron

A turbo collects waste energy (heat and pressure) from the exhaust and uses it drive an impeller on the intake side which forces air into the manifold. A super charger runs off a belt that is connected to the crank shaft. The belt turns a positive pressure helical compressor (most commonly) which in turn forces air into the manifold.

See wikipedia or howstuffworks.com for more in depth info. The reason people are ignoring you is because there is an ass ton of information on this topic that is extremely easy to find on your own.

mdkxtreme

oooh, google, never heard of it. any ways, thanks for not ignoring me :P

Impulse05

I thought the CT Supercharger came with an ecu specifically for it .. regardless what is so different about an '04 ecu that allows the SC to work with the AT and not the '05's AT? and do you think there would be a way to re-tune my '05's ecu so that it works like the '04's or just works with the SC if my only option [in terms of ecus] is to swap?

ThirdLane

CT SC comes with a reflash not a ecu. An 05 AT ecu is different than the 04. So unless you swap to an 04 ecu, you're SOL

northbridge

the 05 AT ECU cannot be reflashed due to a problem with the VIN. I wanted to have mine reflashed... Some helpful azine members explained why it wont work

The Comptech SC wont work without the re flash.

PrecyseStylez

get an 04 ecu and run the supercharger.. your best and for now ONLY bet!

DAYTA

You also have to get the matching immobilizer with the ECU if you do end up going through with the swap.

IIRC, I believe it costs around $5-600 for a used 04 ECU/immobilizer, so ultimately you'd have to tack that onto your total price for the S/C.

tdottsx

will the super work on a 2006 auto?

DAYTA

because there is currently no S/C-specific reflash for the 06 AT (although there is a standard reflash).

tdottsx

any word of them ever making a reflash for it?probably not, i would assume.

Impulse05

one of my buddy's fathers owns an Acura dealership and one of the sales reps there cought word of Acura discontinuing the CSX and bringing in a TSX type-S he told me it may be realeased in a few months or next year. One of the thoughts was Acura was going to give it a similar engine if not the same engine as the RDX with that nice little turbo it has. He doesn't seem to think they will go that was because of cost. They will probably just drop a V6 in there oppose to a 4 banger turbo engine. Now this is just "hear-say" but that would be pretty awesome!!

LukeaTron

Welcome to the last 12 months of the rumor mill.

DAYTA

Based on the fact that the 07-08 guys most likely aren't ever going to see a standard reflash, I'd say the chances of Hondata coming out with a S/C-specific reflash for the 06 AT are slim to none.

Impulse05

I wonder, would it be possibly to drop an RDX engine in a TSX because they are roughtly the same size and just "upgrade" the turbo on that engine. [and obviously re-tune a few things] just a random thought .. the question is "hypothetically" could it be done?

LukeaTron

The RDX engine needs a lot more room for the turbo plumbing. Then there's the issue of the transmission which is obviously AWD for the RDX that would not work at all on the TSX. You'd probably need to use an RDX instrument cluster or be wicked good at hacking electronics on top of all that.

In short, to get that motor into a TSX would mean a car that is not at all a TSX anymore. It would be very Frankenstein.

I've seen a K20A+Kpro+patch harness+K24A ecu work. You lose the immobiliser function and VSA.

Impulse05

Im pretty new to all this .. what exactly is a K20A+Kpro+patch harness+K24A and what does reflash mean. yeah most people would probably slap their heads to that question but everyone has to ask and learn at one point.
