The "rats nest" is where all of the hoses are solenoids all gather, right below the upper intake manifold. If just one of those came off the solenoid, or if it were cracked (because of heat build up), that may be why you arent boosting properly. Ill get some pics up in a sec.

 

Rats Nest

Rats Nest (extra Crispy) lol

 

you could have a hairline crack in your y-pipe. the stock y-pipes are known for splitting underneith and looking okay, until the boost kinda pushes the crack open.

Could also be a solenoid issue, maybe your second turbo isn't coming online.

Buy a boost gague, you should get 10PSI at 3000 RPMs, should drop to 8 at around 4500, then go back up to 10 just after it drops to 8.

And 38k miles is a lot for the precat, remember these are rotaries with two heat producing turbos. your engine bay is hot as hell, and the precat is known for failing at any time, even at 38k. And if your precat fails, the debris will flow through your exhaust and clog your main cat.

It's also possible you might have overtightened a coupler on one of the plastic IC pipes and cracked it around the coupler.

 

forget 38k... your car is still 14 YEARS old.

 

...... just to add, my poorly running auto beat a rsx type s from a dig.... and he launched it well. Good luck finding that problem. I hated looking for my boost leak.... p.i.t.a.!!! But, when fixed, huge difference!
_______

do you get that nice rotary smell in the morning? If you do, its a sign of your pre cat/cat is gone.

_______

But, as suggested, get yourself a boost gauge and see whats going on. (Boost gauge is useful later in the long run when further tunning is done anyway, definately a must have)

Later,
MazRx7Fd

 

+1 to everyone, you need to get a boost gauge to see if you are loosing boost at higher RPM, might be a secondary turbo problem

 

Ah, every FD I've ever driven has had at least an intake, downpipe, hf cat or midpipe and a cat-back. I've only ever even seen one that was "almost" fully stock(it had an Efini Y-pipe, any the rest was stock), but I didn't get to drive it

 

y-pipe dosent give HP. From what i know of. i think its my secondary prob, and that rats nest scared me! Ill let you guys know when i get my boost gague and see whats up. dp, hf cat, pfc are going on soon, so clogged pre/cat will not be any concern. Ill record the race after i put the parts on. Wat solenoids, or hoses are related to the secondaries???

 

Actually yes, the Efini Y-pipe gives a bit more power over the US Y-pipe.

 

the Efini y-pipe flows better than the USDM y-pipe, but what you should be concerned with is not the power gains of other y-pipes, but more the power loss you might be experiencing if your USDM y-pipe is cracked or split.

 

Armanmaxx, please do not be alarmed. As the first member to give you a unbiased response, the rsx-s is as underrated as everyone here makes it seem. At 210hp + 6 speed and no lag of turbo, that thing is very nice out of the box. When they have bolt ons, they respond well, due to the fact that they have intake, and exhaust valve timing. Its one of the best variable timing systems on the car market right now. Basic bolt ons on these cars can beat your mustang gt's, and the like. They can even pull on your evoviii & iv's up top.

If you don't believe me or others here have your doubts, please feel free to go to a track and see what these cars run. The k20a in that car makes for a lethal swap into many older, lighter model hondas. Not saying your rx7 is slow, but technology has finally caught up.

Every one else claiming they smoked rsx-s with your autos or your fc's, unless your car has compotent modifications, I'm calling bullshit. And even then, with corresponding mods on the k20a, you bet you will have a run for your money.

Here is a video foir some piece of mind http://videos.streetfire.net/search/...3300f34e2a.htm.

Flame if you please, but I was a rotary fan for over 5 years, and had 2 rx7's myself.

Ofcorse this doesn't apply to heavily or moderately modded turbo 7's (if you ARE losing to the rsx-s, WHATS WRONG WITH YOU?...heh).

*steps off soapbox*

 

rx7henry, realize that while the car may not have turbo lag, it also make considerably less than 210hp before the whole VTEC thing, so turbo lag really is moot. And besides, FDs with stock sequential twins don't really have turbo lag from a roll, unless he started in too high of a gear, which isn't the case, as he was in 3rd gear at 50mph for this race.

 

I understand. The point of the valve timing on the intake AND exhaust is to have a very close to perfect ratio for air flow. While it will not make the 210 or whatever horsepower at a lower rpm, the torque curve is MUCH better looking than the torque figures from the previous b series and h series vtc engagements. I hated the damn car until one of my good friends purchased one and did intake along with a kpro tune (thousand dollar ecu reflash, but on this car its like gold) and his car respectively can break 13s with no other mods.

 

ummn ok...

I am sooo not impressed...

Armanmaxx,
There is something going on with your car.

 

At 38k miles from the factory with no mods? Going bad and needing all types of replacements? I guess thats a Mazda for you then, but seriously, I expected you guys of all people to look at time slips more over dyno sheets. Supras are dynoqueens too, but bringing back 1/4 et's and trap speeds is another story, which apply to actual DRIVING ON THE STRIP. Hey, rx7s are fast, but that doesn't mean other manufactures can't make cars that are too.

Both cars have potential for going fast, but is that unacceptable or something? Your cars at those mods should have been neck to neck, but some of you posters that say that "the rx7 will pull buslengths in 3rd gear" needs your head straightened. You act like the other car will hit a wall in terms of acceleration.

I am glad you were brave enough to make this post. Many others that have probably lost countless times are possibly still in denial, would just begin hating on it rather than accepting.

 

Nevermind, missread.

 

I linked a video above if you missed it
http://videos.streetfire.net/search/...3300f34e2a.htm
02 Acura RSX Type S: Bolt On's, KPRO Tune, Nitto Drag Radials 13.87 @ 102MPH

 

For some reason I thought you had said 13 flat. That also says "bolt-ons", is that the normal i/e/h?

 

are you serious??? a FWD car with LESS horsepower but equal in weight keeping up with a RWD car in the 1/4???



By the way supra's have trouble braking into 10's because of traction issues. But try rolling one on the highway and see what happens. This is not the case with an rsx. A 180 FWHP car ain't braking into the 12's (or even 13's) that is unless it weighs 2000 lbs...

if you say so. But so far all you have provided is your biased opinion and yet have given no facts to back your reasoning. That is other than your butt dyno saying the rsx-s is fast and is something to be reckoned with straight out of the box + a few mods. With that said anycar can be made fast is you have $$ to do it.

 

Like everyone said, something is wrong with your FD. My bro FB GSL-SE would hang or once in a while leave them behind. 3rd gear on RX-7 that is the main and powerful gear right there.

For those saying that a FB cant take a RSX-S. These are my bro set up.

Racing beat header, 2 1/2 inch pipe to a flow master muffler, 6-port racing beat intake w/ 650 holley carb. holley fuel pump.

 

ok here is one:

about a year ago ago I was heading to my GF's and some dude in a black RSX - S revs at me and enticed a race... Whether he actually thought he had a chance I don't know, needless to say he got smacked at low boost (10 psi). It wasn't even close, I'd swear I had a car lenght on him in first gear alone lol. I never came in and told the story as it was nothing to be excited about.

 

Well, the fd has maybe 15+ years of auto r & d and indeed they are fast cars. Well expected to have them running such good times. The rsx has been out maybe 5 years, and they have managed what they have accomplished.

I am just praising them as technology has given us a quick car that is fuel efficient (25/34 mpg) as well, with less than 2000 cubic centimeters without forced induction. God knows a 2.0 rotary will make tons of power, but keeping the decibals down, and getting the fuel efficiency it does, it doesn't look like they can market that engine in any car as of now.

If I were given the option, I would own the rx7 ofcorse (I love the fd3s but couldn't afford the upkeep right now, and have enough toys to keep me busy) and never buy the rsx (I am just a fan of its engine engineering). Just don't go out and expect it running stock/stock boost to be the fastest car on the road, and if your not at stock boost, or even close to stock, and ARE heavily modified, save your gas because we all know you will blow the doors off these things.

 

BTW most of the times for the rsx's you have are non turbo. I don't know about you but a non turbo 2.0 is pretty impressive in my books at those times. All those times on the rx7 are turboed. Will a non turbo 1.3 run those times? Not for a long shot, and if they did, the noise, and gas mileage would make for a hideous car. Again, I'm not saying that the rsx is by any means fast, but being in the correct weight class, they will make for a fun and spirited race against an rx7.

 

The FD wasn't engineered to be an NA car, so that doesn't make much sense. But that's neither here nor there, we're just saying that he shouldn't be beaten or even come close to being beaten, by an RSX-S with a CAI, which is the truth.

 

Agreed, but note that the touring model and r1 models have slight differences. A stock rx7 on a bad day can and may be 14 seconds running down that strip, and the rsx can be 14s on its very best day running that same strip. I figure the touring models pack a few more lbs be it noticable or not. Anywho, it was his cousin that he indeed raced so he can probably set it up again anytime, and I would love to see the results after he does some tune ups, or repairs to that rats nest.
