Hondata 4bar map sensor (stock will not get me the hp numbers i'm looking for)
http://i174.photobucket.com/albums/w...ps125a245c.jpg

whats the advantages of a 4bar map sensor? and where can i get a re-route tube for my BOV?

Doesn't the stock map sensor read up to 26psi?

^ yes it does, per hondata


im still curious on what the advantage of a RBC intake is over ours.. i think the runners are close to the same length.. and i dont think the inside diameter of the tubes are that much bigger.. i would like to know more specifics about the 2 i may just op for a zdx throttle body and call it good myself

Haha, well the runners are much wider and the plenum is like night and day difference. Combined with a 70mm bore will be killer with force induction. Trust me, it is a better flowing manifold.

This will be a trail and error mod. Not sure if the Auto tranny excludes the RDX Sport shift mode.

This whole set up should make some killer top end power..U sure you don't have a bigger turbo on the way that's why you have a hondata 4bar? I cant see the stock turbo going past 18-20psi

will there be pics for comparison? :wish:

also you didnt answer my other question.. where you find the piping for the re route for the BOV?

I'm not sure I will have any comparison's with the two manifold, I should have put it on the dyno before all this. It's just a 1.75" S pipe from ebay with coupler to connect each end.

I'm still looking for a company that will upgrade my stock turbo, but haven't found any yet. Anybody know of companies that repair and upgrade stock turbos?

you'll have to detail and list/link all this!!

Yup. Evergreen Turbo out in Naples, Florida. Charlie rebuilt, upgraded to an 18T, balanced, and clipped the turbine side. He cleaned up real good and coated the CHRA. 352-497-3469

Here's a size comparison the 18T is slightly bigger.

And.. The clipped wheel.

Thanks!

Yw.

Ocala, FL not Naples sorry. Can't find the edit button...

Nice build. Sell me your stock rdx injectors :)

so the rdx intake manifold does look a smidge shorter.. where you able to check the runners inside diameter for comparison? that zdx throttle is a huge different cant wait to see if it is worth it:thumbsup:

how much was it to do this? and how much more hp can the 18t put out?

I will try and take some pictures of the runners later today.

Everything about the K23a1 is small, but the displacement. :sad:

be nice to have that manifold extrude honed before its set in... lol

Disconnected the battery for about an hour for the throttle body relearn procedure, now time for a test drive!http://i174.photobucket.com/albums/w...ps4d33290f.jpg

looks good... whats the end result? i am sure tuning is going to be the best answer.. any rattle sound from the intake tubing hitting the hood?

I couldn't really get on it, I have to burp my cooling system tomorrow. You will have to modify the duct for the intercooler to prevent tube from rubbing it, quick shave and it is good.

Trim air duct
 

Holy SH@#! Ok, after I got the ecu back from Honata the reflash was good, but it would only pull for the first 4k rpm then tapper off the boost.... Oh, not now these thing pulls hard as F$%#!! I took it out this morning, and had to let off because I was going way to fast!! Can't wait to put the cams in, get tuned and take it to the track. I'm sure the "World Record white RDX" on YouTube will be crushed! Stay tuned.:smile:

I would keep the engine cover on
