rohit.

Good stuff man, this was much needed

RDX_NRG

so if i'm reading this correctly, can you have these mods together without any AFR issues?

Hondata, ATLP, CP-E, and 91 Octane fuel?

What about if you add the ETS TMIC?

BigHatch

...what if you drive on a colder day? ...same thing. intercooler is fine.

RDX_NRG

what about the combination of ATLP, Hondata, and CP-E and 91 Octane? would this be ok for AFR?

What about the report done by Hondata (link below):

http://www.hondata.com/reflash_rdx_intake_test.html

Mr Marco

91 octane? Why are you buying 91 and not 93?

user65

Probably in a state that doesn't have 93 readily available, like myself in Cali.

The hondata combo list above has been determined to be safe in other forum posts. If someone finds a different conclusion, the list will be modified to fit such a scenario.

Of course performance mods should be done at your own risk. Understand that many of these mods would void the manufacturers warranty.

RDX_NRG

i think there should be some explanation that the Hondata list with Cp-e intake with other mods may lean AFR ratio too much.

Argh, more mods....

not a mechanic, I'm a driver, but related question for an RSX. I had to get a quick-fix car and found a great 2002 RSX base...like the car so much, I'm thinking I might just upgrade the engine and start modifying to keep it for the long run. So -- what engines, theoretically, could I put in a 2002 RSX base, currently with a 5-speed manual.

I figure I can swap it out for a used RSX Type-S engine which go for about $4000(?), was wondering if something more exotic like a Porsche Boxster S engine would fit into a 2002 Acura RSX?

Thanks.

bluecarbonfiber

RSX??? you in the right forum? haha.. who is your supplier i want your weed =)

08FLrdxSH-AWD

Boxter engine in an RSX????

That is such a crazy idea and im not sure how that would even work.

Archaeologist77

Ha yeah crazy, if custom parts could be made to fit and a Porsche engine fit into the Acura engine compartment it would rock! Not in wrong forum...just thought you guys might have expertise as this is an engine mod thread...looking in RSX forum for an answer as well.

In general, The flat "boxer" type engine would have been awesome in an RSX I think, but Acura never went the way of Subaru and Porsche. Winning rally car engine type or Subaru that's for ure.

bluecarbonfiber

rsx type s engine is your best bet.. no reason to slap in a rwd engine in a fwd car unless you have thousands of dollars and are super bored.. you could just get the type s head and a few internal things and i believe the base becomes the types engine with out the huge dent in the wallet.. but the next big thing would be boost to add the HP.. the k20 engine is a solid platform and if done right can be made to be just as fast or faster then a fr-s on boost

Tizzil84

What does cp-e stand for not fimilar with this term.

EcLm

CP-E is just the name of a brand. Custom Performance Engineering.

DRR98

Soon to be added to the list...Flashpro

Mr Marco

Maybe you should take that money you'd be spending on the RSX and use it as a down-payment on the Boxster...

Thanks a bunch for this. I am thinking of doing a few engine mods, within reason, and trying for the most bang for my buck. The two things I should go for is an intake, and the Hondata Reflash....my question is this if that is all i am planning on running, what intake would you guys all recommend??

On paper the CPE looks better because of the additional HP, any reason to go with the K&N over CPE? what sounds better?

i have heard of the lean issues, with CPE and hondata, but is that only if I run more mods? surely just a CA intake plus ECU reflash will not cause that? but what sounds better?

Also what will be the difference between the regular flash, and flash pro? If all i will be running is an aftermarket Intake, should I be just getting the regular Hondata reflash? or waiting for the flash pro?

user65

I wish the mods would let me edit this. According to hondata the k&n and reflash is too lean. They recommended against running the intake until the flash pro was done.

Awesome compilation!

Hello all, I guess this is my only means of introducing myself since i cant start a thread.

Names Steven, Im coming over from 8thcivic which is the forum for the 8th gen civic (06-12) incase it was not obvious. I am in the market for a daily driver so that my 08 Si can take a break and become my weekend/Track car. Im 6'4 so the RDX def jumps at me at a good potential daily. Then the awd Turbo k series just screams BUY ME!

Now, from what i gather there arent many high horsepower RDX's out yet. I want to assume it is because the Flashpro was just released a few months ago and that is the main reason no one has pulled the trigger and made this thing really move. If not, than there must be limitations that i have not yet learned about (Weak Trans, Drive Shafts ect).

Regardless.. Im really interested to know whats the most extensive build on here for the RDX is.. Whos the big boy on this site maken the most whp, and if there arent any stand outers just yet, Why not?!?!?!

Just a little back story ive run Flashpro in my SI since i think 2009 if im not mistaken when it was first released (def the first day it hit the shelf as my unit is number like 000024). It was originally made for my generation SI and since has been appiled to other platforms. My car was first running a 100 shot of nitrous with usual bolt ons (I/H/E). As she sits now she is Supercharged running an 12 lb pulley with a whole mess of fabricated tidbits, 1000cc injectors and a custom tune from VitViper.. Im sure hes already on this site making his rounds. Hes a pretty great tuner and has 8thcivic basically, completely monopolized lol.

SO to conclude my novel, I currently drive a 350 whp 08 Civic SI. Im looking for a daily. A turbo awd crossover sounds right up my alley but i wanna know that i can make this beast move the way id want it to (400whp+). What do you guys suggest i read? Links to threads or such with any information would be greatly appreciated. I tried the search function but this forum operates a little differently than what im used to so it didnt work out well for me.

Thanks guys! I would love to join this community and make some awd turbo POWER! Whilst being very comfortable and enjoying some Acura glamor lol.

DatBigDude

Just realized i can start a thread

bluecarbonfiber

most HP ive seen/heard so far is the 250 listed on the hondata site.. but 240hp is where they marked it.. no one makes a bigger turbo for the vehicle so it would be hard to squeeze out big numbers.. the DP used in the dyno was a smidge smaller then the RV-6 and the person didnt have all the bolt ons you can find.. so with that said i am sure 260whp is do able.. beyond that who knows.. i would love to see it in the 350hp area which would make it a great sleeper..

well as soon as I get home and bolt on everything but a cat back ill let you know what numbers I post.

DatBigDude

That would literally be the only reason i would pick this up.. If not i would sadly be stucking leaving the Honda fam and getting into a Subie

Sounds good man, i hope you break traction lol

bluecarbonfiber

little love to it that its going to be hard to get above 300 anytime in the next year.. we are still figuring out things, if you own a oil company though anything is possible

BU

I will recommend you steer straight to Subie.
You will get zero to none aftermarket support with RDX.
You have to do your own the R&D, trail & error.
We are fortune enough that Hondata granted us the Flashpro and BC Racing with the coilover, RV6 with DP, Heeltoe with ATLP exhaust, ETS with TMIC.

Subie parts are cheap. Alot of compatible/interchangeable parts between Subie family.

Subaru is garbage. They make crap for power. The motors are junk. They need to be built before you even mod them. Weak pistons and oil pumps. Get an evo if you want to make power.

the truth is that if you leave the cars stock and drive like you have a brain in your head then they usually make it through the warranty period with nothing but regular maintenance. once you turn up the wick though they all have weak points. the subies like to pop cylinder 3 iirc the evo's suffer from oil starvation in older models. the benefit of the RDX is that its quick and unassuming. I drive a brown one the only ticket I've ever gotten in it is the photo cops. :/ and with what is available for it its a reasonably fast family hauler that the cops don't seem to notice.

bluecarbonfiber

^ true statements.. plus unless you get an sti the value of a subie doesnt hold as well.. if memory serves, up until recently you couldnt even get luxury items in a sti..

Vinnyd00

the don't make crap for power and if they are tuned right they work just fine like any other turbo car. Slap some random non thought out parts on there, dont tune properly and yes you will blow your motor. I had a 493awhp forester and I put over 10k miles on that setup before I sold it. It did have a built engine when I sold it but I ran a few previous set ups ranging from 380-420awhp before the build with no issues.

That being said evos do make a lot more power a lot cheaper but don't offer a crossover size vehicle with a turbo so you are comparing apples to oranges.

I just picked up my 2011 rdx with tech today and look forward to learning and modding

Agreed. I also came from a modified Forester XT and if you want a cheaper (i.e. assuming everyone not going to just buy a Cayenne Turbo S) "suv" to go fast the Subaru is a much better route (especially 07-08 with manual trans) than the RDX for two reasons. 1. Weight - 2008 Forester 3,320, 2008 RDX 3924 (that's a bit of a difference) 2. Mods and community mod experience - is/was a great deal of work done though its dying a bit now because they stopped making the manual in 2008.

Having said that, the RDX is much nicer than the FXT was so its obviously give and take like anything.

Bimmer4me

True on the FXT but with the acura you don't have to worry about head gaskets every 100K miles and all the other Pita maintenance like on Subaru.... Speaking from experience with an 01 2.5rs and 05 saabaru

b123

Don't think I'm disagreeing because I do agree Acura in general and RDX specifically are by the numbers more reliable than Subaru. However, not really many or notable head gasket issues with turbo Subaru engines. I doubt anyone's buying a non-turbo Forester for performance. Again though don't think I'm disagreeing or knocking your point especially as I sold my FXT and bought an RDX. Loved the Subaru (and never stranded me) but more issues/felt like it might fall apart compared to the RDX.

Complete side note but best article I've seen on Subaru head gasket issue/causes here http://allwheeldriveauto.com/subaru-...ained-part-ii/

Great reference for my CAI search. Thank you!!

Does anyone have a link to 600 & 800cc Injectors? Turbos?
