Hi, my ultimate major work.

k23a1-k24a2 head (RBB tsx)

Bottom stock.

I ll have to go dyno, run so lean now.

Pictures speak for itself:

2009 RDX, 720cc, flashpro, RV6, ZDX flow, skunk2 intake manifold, water intercooler, ARP stud, BC cams, ferrea valve retainer, k24a2 head ported.

Do you have any coolant going to the manifold anymore? Might not hold up long. Good luck on the dyno

Haré romel

Of course, external inlet, it can be seen circled in the picture. if I don t do that it could melt manifold.

Slow98teg

Oh ok I see it now. Missed it the first time. Are you running a 25* vtc gear or 50*?

Haré romel

RBC 50 vtc gear

KenB350z

Nice!

DDTsx06

no write up on how to do this? was it hard to do? did everything mount up correctly. Nice job btw!

Haré romel

Pictures speak for itself, major work was the exhaust manifold (look circle in the picture), close water port, drill to move bottom bolt, adapt external inlet npt fitting. also connection to return all external port to water pump inlet (not to radiator for continue recirculation), oil cap below water intercooler (I ll have to remove for oil change) , but the complete head fit perfectly (you have to use all tsx head part, cover, water port,...... )

THX...

Haré romel

Thx...

You help me respond some question to do this, thanks again.

Haré romel

Hi all, I have problem with the exhaust manifold, it broke inside after coolant liquiq by one hose fault, this manifold is very delicate with the temp. I go for aftermarket exhaust manifold. I recommend not do exhaust manifold modification.

KenB350z

Other the that, how was the k20 head?

what is with the turbo compressor wheel? thats not stock is it?

Haré romel

Excellent, more hp at less boost, high reving fast, i tuned by myself to proof if all is good, but :-( exhaust manifold damage.

Haré romel

Yes, that's not stock, I did turbo upgrade with other company, +70 hp stock housing. There s +100 modifying housing but you have to adapt some parts. I didn t want do modification.

Now, i have big problem, probably i mount t3 turbo as kenb.

Haré romel

:-) Some parts:
- Garrett To4e turbo oil cooled ( Let s see, later i go for ballbearing water-oil cooled gtx30)
- Cast iron manifold
- tial wastegate 38mm
- oil feed kit
- oil drain kit

Haré romel

Begin work, I hope fast spool necessary for heavy rdx.

KenB350z

Haré romel

still working...

KenB350z

Yeah buddy!

KenB350z

How is it coming along?

Haré romel

Sorry, I was traveling, but I'm done.

Looks same as before

It accelerates fast, feel great, without tuning, I'm just proving reliability, now. But,
turbo load slower 1800rpm oem vs 2500 rpm to4e journal, but excellent after loading.
The external wastegate sounds too much outside, I will connect it to downpipe.
I sometimes have p2263 code, I do not know if I have a bad connection or I need to tune.
I ll check that.

But overall I love it.

bluecarbonfiber

Makes you wonder with the new civic type r that has a turbo if there is any compatible parts with it

KenB350z

Nice! P2263 code, haha; who cares!! You can kill just about anything on the road now. The code is because of the turbo. I had that, but not really worried about it.. Dude PM me your location, would love to meet up and check out your setup!

Haré romel

haha, I don t worried about because this don t affect boost control, but I ll like hondata disable that code (p2263 - p2261), there re many people with oem turbo that have code them.

Thank you, it would be a good idea to meet, but I'll move out soon, so I'll let you know.

Haré romel

Hi guys, external boost control and flashpro low value boost control resolve p2261 code but I ve check engine light on present just p2263 now.

feel good just at 9lb

KenB350z

Nice, I should have my K20 head in the machine shop this week for a valve job. Can't wait, sounds good!

Haré romel

Cool br, post your mod when you do it.

Haré romel

Bye stock exhaust, welcome 3" complete custom magnaflow exhaust, no sound with straight through, excellent....

KenB350z

Yo, looks pretty dope! Can they make a duplicate?

Haré romel

No, was custom make, I bought magnaflow mufflers and tips and he did everything.

KenB350z

I will have to say, with the traditional VTEC head this thing revs effortlessly!

Haré romel

mmm, I dont think so, i m with 11 psi, street fuel, vtec point 7300rpm, 7600 revlimit now it feel very well, i m planning 13 to 15 psi with street fuel to see if engine knock resist. Dont want pay race fuel. i dont have bb turbo (t3 to4e), i would like to install gtx28 gen2 to see if check engine off or gtx30 gen2 for full perfomance.

Cam adv, ign... are very different, i had to work hard in this map. I recommend to work hard in your tuned. Remember you have now factory cam and before you had bc cam, Me bc cam a1, now bc cam a2.

KenB350z

I was able to drive on the old map. If you don't run enough boost, you will get a check engine light. Yeah, the aftermarket cams have a more aggressive profile as far as the lobes go.
