Impossible to get 280WHP from the RXS Type-S using todas system. The 02-04 RSX"S dyno around 165-175whp STOCK the new 05s Dyno at 180whp stock,


If you get a Hytech kit for the RSX which costs alot of money You make 300whp with an 10kredline, S2000 DOES not respond to mods AT ALL You would need to spend 10,000 atleast to make the car run low mid 13's


Friend of mine spent ALOT of money on his S2k , He did ITBS, Headers,Intake , exhaust,flywheel, he would normaly get 13.8 13.9 HE HIT 13.7 once Stock S2ks WOuld hit 13.9 with a good driver


With the s2k you have another alternative, Gears ( Final drive ) This costs about 1k installed this with a flywheel, you would be able to run with M3's S2k with gears beats a stock s2k a bus. Basicly running around 13.3 / 13.4


Back to the RSX



Intake, Race headers , Exhaust, ITBS ( individual throttle bodies ) IPS k2 cams , enjo MMs type-r valves , Toda intake manifold , type-R pistons (stock w/ 05s) , flywheel, Short shifter, oh and lets not forget Type-R Final drive and most important mod of all Honata K-Pro , Tune this car right and your an N/A Champ!


estimate of WHP id saying 235WHP N/A



low 13's =)s w/ some drag radials if you could drive high 12's



iv seen some ppl hit a consistent 12's N/a w/ some weight reduction.




I love hondas

thats because we dont have as much high end, If our cars had more High end and didnt loose HP pass 7800k rpm im sure we would do better not saying win, but better...

Pkskull77

Wow I had no idea that car was so much faster than the 8. I didn't have any sound, was there any modifications done to the Z? If not, Mazda has some work to do, because you can't be that much slower than your biggest competitor when your selling sports cars, even if the car is more refined.

Z killer?

I'd be happy if I could kill a minivan.......

while it will not be cheap it is not impossible, just looking at some of the numbers : her RSX (03 typeS) did 5 base line runs at 174-176hp (all same day, same conditions) With her CAI she saw a gain to around 184 if I remeber corectly. We also added the motor mounts at the same time, that didnt give us power but helped with launch.

With that setup, about 185ish WHP she ran a 14.4@91 I think, then we changed out to the old Falken asenis sport tires and get a 14.3@93. With a street tune on the less than stellar VFACII we got ~192whp and gave us a 14.2@95 (really helps on the top end pull thru 3rd).

With the addition of race header and catback, along with a retune of the VFACII (on dyno) we are planing to see about 210whp. and hopefully we cna get close to 14 flat.

The TODA cam kit (new cams, springs/retainers, header, catback, intake) is getting cars around 230whp.

We plan to combind that with built internals and the 11.5:1 compression pistons, all balanced and blueprinted together, match that to the toda head gasket that will bring the compression close to 12:1.

At that point we NEED to go with a stand alone ECU, since the piggyback/reflash wont cut it or give us the ultimate power from the mods.

We will tune the car for 98* gas, that should give us right around 250hp...near the flow limits of the stock intake manifold/head.

Then we will be going to a ITB setup with a fully worked head (ports, valves, ect) that along with things like flywheel, syn fluids, plugs, wires, coil packs, injectors and ECU full tune should get usnear our 280whp goal (about 320 cranh HP or 160hp per liter).

--------
Im estimating 12k ish for all the parts/dyno runs and tuning we can do almost all the work in house. Money well spent? To each his own.

It wont be cheap and it wont be easy but its out ultimate goal, although when you combind the weight savings on the car from changing some of the parts out, with the additional power, I think this car will be quite fast and more than enough with 250whp. So as for how far we really go, i dunno....we have a plan but might stop along the way, due to cost or just cause well get to a point that the car feels good and we are happy.

Keep in mind we are mixing and matching parts to try and get the best parts of each kind on the market. but if you were to order ALL the toda parts (some dont work together such as the pistons and stock cams) you would basicaly be building pretty close to a TODA race engine, and their engine make INCREDIBLE power, given the displace ment. our goal is not to build a race engine, as we will still street drive the car, obviously the extent we are modifying the drivetrain, the car wont be as reliable as stock but will be drivable (not a daily driver, weekend/track car) and will have the service dont at home at much closer intervals.

right, i totaly agree, all the basic bolt ons will net you maby 10whp. Not much, with a perfect launch you MIGHT drop .1 ET or gain 1 or 2 mph trap. The car already runs high 13's stock (s2k) I was agreeing when i said that Ive seen STOCK s2k's beat up on I/H/E RSXs (just the botl ons, no tune). Case they are both putting down about the same power (210-220whp) and they are very similar weight (2800-2900ish) but the s2k has the drivetrain advantage (RWD). part for part the RSX could be made to beat a s2k, although neither of them is really a drag car....but we wont get into that argument.


again i totaly agree, the s2k is a high 13 car, but JUST barely. The fastest ive seen 'stock' is 13.8x@xxx, the only things this car had done was sticky tires (DOT legal but they were basicaly treaded drag tires, the BFG's i think) and the cam sensor had been wired so the car was always in VTEC cam profile. but there was no tuning or bolt ons. It was faily slow off the line, but picked up quite a bit come the 1/8th mile.


Again totaly agree, The above bolt ons with gearing can and will net a good driver low 13's NA.



i posted my plans above, but will say to you, the 02-04 (US Spec, not sure on others) is 11:1 comp ratio, the Type R is 11.5:1, making 200/220 hp respectivley. The 05 (US Spec) got a bump of .1 to make it 11.1:1 comp ratio, this along with some ECU tuning gave the car 210hp (to the 220 or the typeR) please link to any information that says differently. The type S is close to the type R but its not the same car (as some think) there is a differnt suspension, exhaust, ecu, some internals, ect ,ect.

I think the above is talking about the rsxS, i have no doubt the car could be made to hit high/mid 13's with good (street legal) tires and a LSD, considering we are at 14.2@95 with just Injen CAI, VFACII tuned, motor mounts and Falken tires. This is the car with FULL stock weight (only thing we have that is differnt than how the car is run on the street is an infinity BASSLINK sub in the back hatch area, about !25lbs. We did these dyno runs with the back seat, spare tire, jack, pass seat all STILL in the car, unlike others. With a few more bolt ons we plan to see closer to 14 flat and could go lower if we lose some weight out of the car, but we want to see how fast the car can CONSITENLY be with the same trim its run on the street. Since this isnt a drag only car, we want to run on sticky tires that are not only street legal, but have a nice firm side wall as the car has a full suspenion and sees active road course duty. So the falkens were a good choice.

We could get the car faster with out adding much more power, but we like to rune for good midrange and top end, rather than off the line grunt. If we tuned for a little bit more power from a stop we could get a faster launch/60' and improve out ET. We mostly do the drag racing to get the trap speeds, since that is what shows you your power, not ET.

We love the car and how easy it is to mod, while we use the drag stip to see the power we can make at work, the car (and our hearts) are in road course racing. Also lets face it, its a little 2L 4 banger, not a stump puller v8, it dosent really belong on the drag stip...lol :p

I also love honda, but my heart is in mazda!

sorry for the long run on post, or if I say the same thing over and over, the above post was written bit by bit over an hour, since im here at work.

DARKMAZ8

ARE you a fool? I've raced quite a few 350's and none of them pulled like that on me. There is no fvckn way. I know you're a nissan fanboi but the 350z and g35 are slow too! You want to see bus lengths? go race an m3 in a straight. When I'm in my buddies M3, all the 350/g35's I see drive like my grandma when they see the M. Yes, the 8 is slow in a straight but so is the 350z/g35 by todays standards.

Pkskull77

Thats classic. I've gotten dusted off by vans, it was pretty sad.

playdoh43

I sense some jealous hating here :p

DARKMAZ8

who's jealous? I am far from jealous my friend. I'm just annoyed when ppl come on here and brag about how fast a 14 second car is. "news flash" the rx8 and 350z are both 14 second cars. so what if one is high 14 and the other is low 14. Both cars are still slow.

playdoh43

correction, the G35c is a low 14s car that can get high 13s on a good day, 350z can easily run high 13s. the Z is slow compared to cars like M3 that starts almost 2x as much and thats how its supposed to be. without relative price, Its easy to go by your logic and call any car slow. I can say, M3s are slow, ferrari ENZO can rape it anyday. Or Ferrari ENZO is slow, F1 circuit cars can kill it.

everything is relative, and price is an important factor, and rx8 and Z falls into the same price category. thats why people compare them? RX8 isnt about straightline neways, so i dont see why anyone would get pissed over people saying 350z is faster. I personally would not call a car thats faster than my car slow.

DARKMAZ8

Actually I would argue that a slightly used 2001-2 M3 is the better buy when 350/g35 shopping. All I am saying is that the 350z's speed is nothing to be proud of. wow, 13.9 I stand corrected.....lol

playdoh43

well i think they can be proud of their 13.9, its a repectable time for the price. and a slightly used 2001-2 M3 is a better buy than a rx8 too when rx8 shopping since its in the same price range as the Z. i guess you must feel bad that you got a rx8 instead of a used M3 huh?

you just sound kind of bitter to me, trying to put down another car that does something better than your car. there are owners that are real happy about their car and love their car, and there are owners that regret buying their car and feel the need to put down other cars that does something better in order to justify their decision. real car lovers appreciates all cars for what they are and respect them for what they are.

and FYI my dad being a huge bmw fan has a 2002 E46 M3 that was bought in may, they go for mid to high 30ks used, not exactly the same price range as the Z or rx8. M3s dont loose 1/2 of their value in 3 years.

What it's matter? You really want to know the truth? Park a M3, 350Z, and a RX-8 together and then ask a girl (who knows nothing about cars) which she would take. 9 out of 10 will pick the 8. What's my point? Well, thats just it... 9 out of 10 people in the US don't know anything about cars and base their opinions on looks only. So why not have the best looking one when thats all most people see anyway?

To me, the RX-8 is drop dead sexy and I wouldn't want it any other way.

Pkskull77

Why is it that every RX-8 owner thinks its the best looking car, while just about everyone else thinks its a bit weird looking?

but it's still fwd though right? (ugh)

DARKMAZ8

Playdoh43----I am only comparing the m3 to the 350/g35 because they are simular in the way they execute their power. I could have bought a new m3 if I wanted but I liked how the 8 handled and how it connects the driver to the road without hurting the everyday comfort that I needed in a daily driver. I have no regrets about buying the 8 over the 350z,m3,g35,sti and numerous other cars I testdrove before buying. My point is that showing off how 350z/g35 can beat an 8 in the straights is just old news and is not worth mentioning. 13.9 is nothing to be excited about playdoh43 as I've seen plenty of civics beating 350z/g35 at the track. Besides, the blistering 13.9 that the 350z/g35 does, they pretty much suck at everything else.

KYLiquid

corect, and the RSX in america both base and TypeS have NO lsd...

playdoh43

if anyone think the rx8 can beat a 350z or g handily in the twisties they're in for a rude awakening one day, after racing the skyline coupe and RX8 around tsukuba circuit, professional BMI drivers indicated that the skyline coupe is not only faster on the straights, it takes corner faster too. g coupe also have better skidpad and slalom numbers than rx8.
so they actually dont suck at everything else IMO. Does that mean the RX8 sucks to me? No, theres plenty of things that RX8 is better at, such as its ability to connect the driver to the road and everyday comfort and to some, its aggressive look amongs many other things thats why its beats the 350z in serveral magazine comparisons.

youre certainly entitled to your oppinion dude, if it makes you feel better by putting down other cars then I guess more power to ya. this thread is about relative speed between 350z and rx8 and what mods to put on the rx8 to beat a 350z. if u dont like reading about 350z being faster its real easy to stay away from the thread

DARKMAZ8

First off you're the one that looks bitter. I originally responded to Shiri, yet you decided to exploit your fanboi skills. Have you driven both cars? I have and I'll tell you that the 350z has a much harder stock suspension then the 8. Think what ever you want but the 8 outhandles the 350z even in stock form. show me where it has a better skidpad. From what I have seen they are equal. Remember, tires alone can account for discrepencies with skidpad #s.

Secondly, the 350z has a very cheap feel to it and it rattles like no tomorrow. Also, go find any nissan thats body lines up properly. Most fenders are not flush with the hood ect. This among other things just show how much margin of error the nissan quality control team has.

Finally, This is all based on my opinion and it is backed by my experiences with nissan. I am not a fan of nissan and I personally think that if the 350z was suppose to be the successor of the 300zx, They did a terrible job.

Shiri

You ran a poor driver then if he's only putting car lengths :

Fastest all motor 350z (street tyres) - 13.1 @ 107mph

Fastest 350z - 8.33 @ 176mph

What has the 8 done?

Shiri

Well said! The Skyline is actually a GT (just like the M3) so cornering is not high on its priority list, yet it still does pretty well.

They are all great cars, just that some of them respond really well to mods and are able to go a lot faster than everybody else :D

DARKMAZ8

The 8 has done better in every comparison test I have read.

Am I suppose to be impressed with straight line performance? If I was, there are better options out there that are cheaper and faster. I guess that's why they're so many 350z's flying out of the showrooms.

Aoshi Shinomori

I'm pretty sure the 8 has done a 6 second quarter, with a driver by the name Abel Ibarra :D But I am pretty sure it has totally different internals and maybe a different engine. What about that z? Stock internals? Not insulting you, I'm just curious.

What's the big deal? 2 very nice, but very different cars. Obviously one is going to be faster than the other, is that really something to get so riled up about?

BlueRenesis82

or if you want a 350z killer, get a 04+ Cobra, those things are retarded fast in a straight line, and more power is just a pulley switch away...
