DC5-R head on the tsx
I'm just wondering can we put the DC5-R head with all the cams valve etc in the tsx engine. You think it will give HP

From an NA perspective, yes it's a significant progress.

Hi Noel thanks for the reply if anything is the head with all the parts a direct bolt on to the tsx block or is there needs for modification.

There are components requiring modification, are you also aware of voiding your factory warranty?

And this isn't going to be an easy swap, you'd also need a tuneable aftermarket ECU to get everything working correctly as well.

IIRC, won't he lose DBW and then need new gauges?

Yes, there won't be the DBW function with the effective swap. And there are plenty of ECU options out there for the K20a. Hondata is not be all/end all.

What about running the K20a head but retaining the K24's intake manifold and TB? It should work shouldn't it?

ok that is a very cool topic, I also do have the same questions, I am owning a CL7 K20A 155horse power accord in Hong Kong, I so have the same questions, can I use DC5-R engine parts for my CL7 to gain horse power like Euro-R...

O4 K24TSX - No, that's a conflicting setup. You won't get optimal performance as one setup is bias for torque while the other for high end. You'd need to lose the DBW functionality and use the K20A intake manifold/throttle body setup.

Superx - Your K20A would be better off swapped out for an entire Euro R K20A instead of going about this route. This setup isn't applicable/ideal for you.

Isn't there a sticky in the General Topics subforum which lists the differences already/as well?

how about just fit dc5-R intake manifold to euro with bigger throttle body would it make significant gain ?

when you swap in the k20a R head on the k24 block, you going have to replace your gauge cluster too, cuz the stock tsx gauge cluster won't work with the ecu of the k20*

on the bright side, you can now use the hondata S300 or the AEM e-manage ultimate(pain in the ass to tune) where as you couldn't before with the TSX k24 head and ecu... I might be wrong on this but correct me please.

Cuz i got allan swaping in the tsx k24 bottom end with the R head, on toda cams and vavle springs, and we trying to decide between AEM e-manage or Hondata s300... and some other goodies.. hehehe.

..and when he's not looking i'm going to steel his engine for my car lol

That's pointless and doing more harm that any good if/any. Disabling DBW at the same time in this backward process.

The CL7 IM is designed for mid-high end power vs CL9 IM which is designed for torque and low-mid end gains instead.

Without the proper ECU tuning for fuel/ignition, VTEC and RPMs all you're doing is destroying the balance of what the K24A is designed to do.
