i have a CL-S throttle body and it works perfectly with my TCS, the VSA has absolutly nothing to do when talking about a 3.5L conversion. neither do the rev limiter, the 5sp tranny and well the cams are taken care of by the v-afc...



So you want to do a 3.5L swap with your TL-P heads? You really aren't going to pickup enough power to make it worth it.

It's not my money... good luck.

i said i was doing a complete, well done conversion.. that means i am using correct parts like:

3.5L block (already have it sitting in my garage)
TL-S heads (to be ordered when i have the $$)
TL-S Cams (to be ordered)
CL-S Throttle Body (already have it installed)
V-AFC 2 (to be installed, with the cams)
Shot-Pinged (hardened) rods
Valve Job
Port & Polish Job

plus everything i already have, and possibly transmission work.

dont worry i made a lot of research a while ago about that, talked to people who have done it (like austin519) and listed the required parts, etc...


thanks for your help tho

Type-S heads, cams, and throttle body, but no intake manifold? It's not that hard to send a signal to the actuator to open it up past 4100rpm. That's all it does, open at 4100, close below 4100. I'm sure the V-AFC as an imput, to do this. For example, the VTEC engagement. You won't want to change that because you are still using OEM cams. You won't experience gains from moving it. But what you could do, it set it to engage at 4100 rpm and wire up the bypass valve actuator to that VTEC output. This way you wouldn't have to worry about swaping ECU's.


What pistons are you going to use?

I was going to say the same thing about the intake. it wouldnt be hard to open the 2nd stage actuator. im sure also the v-afc could do it. i too plan on doing this (3.5) mod in the near future.

like i said in a previous post it shouldnt be hard to do it so i might do it but it is not necessary.. i'll prolly do it.

i am going to use custom made pistons by JE. austin has the specs.

The biggest issue i have thought of when doing this with all type-s parts is getting the increased redline. in order to get teh benifits from the cams and intake the redline would need to be raised. with out it the cams will do very liltle as with the intake.
we will have to find a way to increase teh redline

That's not going to be possible with the V-AFC if I remember correctly. But you are correct. You are going to need to rev to 7100rpm to achieve the most from the motor as peak horsepower stays pretty consistant beyond 6500rpm.

it would for sure help, but how would it be possible? there must be a way to modify the ECU setting for the rev limiter..

You can't directly re-flash or modify the ECU. And I don't know of a piggyback system that will work on your car that has the ability to raise the limiter.

Well, not all of their ECU's are like this. The RSX and TSX for example have the ability to be re-flashed. I believe the reason why Hondata never came out with a product for the CL/TL was the inability to alter certain, vital settings.

yea.

honda has always been tough to work with. it took along time for the aftermarket to crack their code

before you even consider the 3.5 conversion...IF you ever do...has anyone though of the '04 TL engine??...or that engine with the 6mt, which will prob lead into the same probs.

about the 3.5L conversion, wouldnt there be a way to "confuse" the ECU by tweaking the RPM signal before it gets to it?? cuz the gains from the cams would be even better... the high RPM is almost a must!!

Even harder (especially in wiring and the ECU due to the DBW throttle system) and you have more potential from the Type-S engine anyways.

yes you would need to find a way to get more RPM thats where alot of the gains are

Buy this supercharger instead. Better gains, more potential, and cheaper.

Um, i'm sure you could talk him down. It's also really hard to find one that is ready to go on the TL-P, but suit yourself.

it would be nice to have it while i save up enough cash for the 3.5L conversion... but then will have have to remove the supercharger and buy a Type-S one to fit the 3.5L engine... so i'll just wait..

i believe they are the same supercharger just a few different small parts that i beleive can be bought from comptech.

as far as i know you cant just buy the parts. i thought someone else wanted to do the same thing (had a good deal on a type s and had a tl-p. wanted to get the part for the acord and they wouldnt just sell that part)

I know for a fact they sell parts to convert an automatic kit to a 6-speed kit and visa versa. Only one way to find out for sure, call 'em up.

hey got on v6performance.net . they have lots of 2000-2002 AV6 S/Cs for sale all the time. These are the ones you wanna buy. and the "moddin" required is really not that much. usually quick fixes and messin' a bit with the pipes (which can be cut'n welded to change angles, distances, make curves, etc = really easy)

i woulnt know, but mr.steve prob has it covered. what do you think?
