Anyone see that Skunk2 has a throttle body unit available (maybe) for the TSX? I was back at the shop again today and while we were discussing the CT-E Icebox we found a Skunk2 Throttle Body with a 74mm internal diameter that was avilable. I said "maybe" above because even though it seems that Google knows all it sometimes lies. He'll be calling them Monday to find out what the deal is. It looks like the part is Roughly $380-400. But it is an increase of 14mm (up from 60mm stock). I'm not sure how this will affect the throttle body spacer and whether or not it may need to be machined out to help the throttle body become more effective but he'll be asking them that question as well. I'll post more information when I find out. This might be a fairly worthwhile mod.

 

thanks for the info man, keep us updated on this

 

Could someone explain in dummy terms how much more gains would you be getting from a 14mm increase in the throttle body?

 

10-15 whp and with a tune you can double that.

 

^ from a throttle body??

 

you can gain another 10hp with some wild unsubstantiated claims

trust me on this one.

 

Yer on a roll tonight. Nice.

I don't think you'll really net any significant gains however if you are planning on forced induction in the future this would help your engine/supercharger to realize its full potential. You may change the powerband a bit on a naturally aspirated motor but either way it would be a step in the right direction especially in conjunction with the rest of the bolt on parts we have available at this time.

 

I am interested in a larger TB, please keep us updated.

 

My friend with a rsx type s got 25whp with a tune. Check out club RSX . Com

 

While anything is possible in the world of tuning, I am specifically arguing the point of a simple bolt-on application due to the lack of real tuning options for this vehicle...unless of course your s/n is chivik and you live in Russia where it seems the possibilities are endless.

I am exploring the S300 application as well but as long as the possibility of a supercharger exists within the next year or so, I'm going to keep the ecu in its stock configuration. No need to screw with it.

The biggest issue I have right now with changing out the t/b is all the tubing leading up to it from the CT Icebox and the spacer. I don't want to kill my performance thinking it is necessary to mill out the tbs and replace the stock tubing with some kind of silicone tubing. So I am waiting for a response on this to see if it will help.

Also, if you are considering a supercharger application, this throttle body will most likely make a very big difference. So, in light of this fact I am trying to get this motor fully setup to accept the s/c with no other modifications required to the intake/exhaust. I hate redoing shit.

If I find anything out I'll certainly post it since that was the point of this thread. Or if any of you find something through your own research, please post it.

 

Just bore out your stock throttle body and call it a day :-)

 

lol! there's nothing to bore out!

 

maximum nooby question: Dont we risk losing power by using a larger throttle body and larger intake tube on a stock motor by increasing flow but DECREASING velocity of air intake to the engine?

i remember this came up before and someone dropped the knowledge bomb on this, im just curious if its possible we may not want to get a bigger TB with just natural aspiration

 

With this size TB, the limiting factor is still the stock bumpsticks. So, while you may not grab much power up top, throttle response will be increased.

On the old F series engine going from stock 57mm throttle to the lude 64mm throttle, there was power up top and increased throttle response throughout.

I would feel fairly confident we would have similar response on this engine/TB combo.

 

The throttle response is due to the fact that by percentage of throttle actuation, there is a larger area opened, where with the orginal TB, it had to be opened farther to equal the same amount of plate...diameter. Does that make sense?

Optimus is correct. That which limits the amount of air that can be ingested at 1 bar (atmosphere, what you breathe) is the cams & valvetrain.

How much of that "30hp gain" was from the tuning alone?

Meh....

 

more knowledge bombs have been dropped.

 

He added the throttle body and retuned it.

Ppl that said that a RSX type S clutch will not fit on a 2nd gen TSX guess again.

Don't look down on someone that is actually down to put in work on their car no matter what the outcome is.

What have you done to you car?

Next thing y'all Know I'll be turbo then talk all the $hit y'all want.

 

Please keep this thread informative rather than making claims or personally attacking anyone. That really isn't the goal here. The goal is to try to find more parts and options for us where the market is weak.

This also probably isn't the best mod for someone who already has an intake or downpipe. Who the hell knows? But maybe with time, availablity and people who are willing to spend the money to dyno, someone might actually be able to make some sense out of all of this.

And one last thing, throttle response doesn't necessarily bring you more power. Just because you can rev more freely or you have a little more oomph in one area of the powerband doesn't mean you are actually making more power. And I don't want to hear anyone make claims. Just show me your dyno charts and that will speak for itself.

Speaking of which, my dyno guy had to cancel yesterday to get his MDX registered at the DMV. Awesome. So hopefully, tomorrow, I'll have some numbers to post.

 

Ronald, the only other person I remember reading about clutches was Rob (Boosted09TSX). IIRC, what he said was that the 08 and 09 TSX are different part numbers, (or part of the assembly is) even though architecurally speaking the engine and possibly the transmission have similar (if not the same) qualities.

I postulated that the assembly or parts thereof might work, too, but it needed to be verified, which you claim you've done.

He wasn't willing to tear it apart on a bet. So, if the 08 does work, congratulations! Seriously, you're a pioneer by default (I'm not being facitious or sarcastic.)

My TSX mods were icebox, tint & TL-S wheels.

My shitbox is the Tacoma.

My weekend car is due for new front axles & VSS, removing the 4" titatnium exhaust, new coolstop Brembo pads front & rear, new struts, repair of one of the 18x9 BBS LM's, and maybe removing the Blitz intakes, installing a replacement cat for the one that was gutted before I bought it, and maybe a pair of stock replacement Garrett GT28RS disco potatoes. So, yes, I'm down for mods, but not on my daily driver. = )

Edit: Sorry for the hijack, I'm the worst offender here.

 

BTW, what equates to about a 25% larger throttle body over stock is a *HUGE* increase (60mm-74mm)

When I was a Stangbanger 20 years ago, the incremental oversize TB's were like 62-65-67 then the 70 & 75 came along, then 77?

Point being...WTH could use a 74mm TB? Or, rather, what original equipment hand-me-down application could that have come from? Pilot/Ridgeline/Odyssey? TL-S?

 

My 57 to 64 wasn't that big a jump. The 64 came from the h23, was bored out by maxbore.

 

hey hevyduty, please post up your modded ride!!!

 

No problemo...it's under the car cover.

 

Nissan?

 

Prius

 

R32 or R33?

 

+1.

 

Subi.
