Some turbo EP questions...

munster · Post by **munster** » December 25, 2004

This is for all of the EP guys.

Stinky is coming home from the Navy and we've been working on a turbo setup for him (03 Si). I've heard alot about the Cybernation kit for the EP, and we think that's what we're going to do except using Hondata Kpro.

I don't know what options there are to go with as far as manifolds for the K blocks. If we had manifold options we'd probably just build our own setup with a custom downpipe and ic piping.

Anyways, my questions...turbo EP guys...what manifold are you running and/or what kit? What are you doing as far as fuel management? If anyone is using the Kpro...what do you think? Numbers, opinions, etc. would be greatly appreciated.

He gets discharged in February and we want to get his car turbo'd along with mine.

If you are a baller and want to make some power

(full-race) http://full-race.com/store/product_info ... cts_id=247

Also these guys make one, it's not listed on the site but they have it, I've seen the prototype in person, nice stuff http://www.one-fab.com/turbomanifolds.html

Rev-hard makes one too, and southern florida performance http://www.sfp.net

K-PRO is the shit, just expect some serious time on the dyno. The i-vtec fuel/timing maps are a bitch to setup.

I saw the sfp one after I made this post. That full-race one is bad ass. $$$, though. haha. I don't know how much he's willing to spend. I know he's selling a GSX-R 600 Telefonica to do this, though.

Thanks for the input, Dwight.

I have the CN kit on my '02 EP. The manifold puts the turbo down low where it fits best and dosen't require heat wrapping all the wiring and what not. Keeps the engine bay WAY cooler. I also prefer my Guardian over a KPro any day of the week. Like earlier mentioned tuning an iVTEC properly on the dyno is a BITCH and if you live somewhere that you have cold winters and hot summers a kpro could never be as well tuned as a guardian as far as A/F ratios go.

Thanks for the input, Eric. I never heard much about the guardian. That's why I questioned it. The cybernation kit seems to be the bang for the buck kit.

What's the K20 run like boosted? Just curious.

NP.

Basically guardian tunes itself on they fly. No dyno needed - ever. It also handles the large injector override and prevents extreneous CELs. It includes features like 1,000 cycle per second tuning as you drive and protectiong the car from problems by cutting you if your car runs lean or your coolant temp gets above an acceptable limit. I am more than happy with mine, especially living in PA. Last year I have to "self retune" for the winter as I was running lean with a S-AFC and the colder denser air. This winter guardian has kept my car feeling powerful without touching anything and other CN stage I EPs with guardian have dyno'd at over 300WHP in the crisp, cold winter.

I personally think CN is the best way to go if your not building it custom. GReddy is too weak and adds up to OVER $4k if you buy the missing items to make it equivilent to what you get with CN and RevHard users with the included reflash have been getting missfires and throwing CELs like crazy with the company telling them to pay $500 to upgrade to KPro as the solution. The only other two kits I know of are SFP which uses Methanol injection (another responsibility to keep the car running) and a new kit noone has really tried yet that has the intercooler mounted where the stock air box goes (LAME).

im not running a turbo, but i am running a built A2 motor with the JRSC race kit, and hondata k-pro, i love the k-pro, dyno time is a must with someone that knows how to use it, me i took a class an have hondata friends that helped out also,
as far as the FM on the CN kit, i know nothing about it yet, i have memebers here in CO 1 with the greddy kit, 1 with the CN kit, 1 with the sfp kit, and the cn kit has to be the best one of all, cause u pay for what u get, good shit,
but then again, depending on what he wants to do to his car, daily driver, weekend racing, ect. the greddy kit put down great numbers here in the cold weather, and super quick spooling, and depenable for DD,

as far as numbers.
my set up is around 275+ still tuning(on small pully first) then 12psi, and wanting for a k24 block.
CN at 10 psi 300+
greaddy with FMIC 280+

Cool. The CN kit was the one that I was leaning towards to begin with, and it seems to be the best so far.

It's not going to be a daily driven car, but he'll put some miles on it driving to shows, meets, etc. He still wants it reliable.

Thanks for the input.

If it's not a daily driver then I assume stage II or more is in the future of this car? If it helps the decision, may I offer that CN is also the only company that has stage II and III cars rolling around owned both by employees and customers.

It's a daily right now, but it won't be when he comes home. I'm sure he's not going to happy with just a stage I
