JDM parts??? I need help

There is friend of mine saying he can get a good price on the following items. Now, my question is is it worth it? Will I get a good increase in power, tq, and handeling? Well here is the list, tell me what you think. By the way I drive a 99 Prelude (duh).

pistons/rings/rods
cams/gears
LSD
ECU..maybe
intake manifold (ported and polished...woo)

or, we can get skunk2 race spec **** like:
intake manifold
ECU...possibly programable management
cams/gears
then get some JRP Pistons
Crower Rods
Fidonza Flywheel
ACT Clutch
port and polish both manifolds
VAFC

Now before you flame him, he is not a Prelude guy, he doesn't have that vast of knowledge concerning the ECU and OBDII and all that so be gental. Thanks for any help!

Well if it's worth it or not is all relative.

If you are gong to tear apart the head and block (read $$$$$$$$$$) then you might as well go all out. Get it B&B'ed, P&P'ed, have the crank balanced and knife edged (if you are going to up the red line a lot), you might as well get stronger rods (than the JDM Type S ones). If you get the Type S pistons you won't have to resleeve the block, if you get the JRP (I think you mean SRP) pistons you will have to.

Crower's cams are supposed to be out and they are about as expensive as the JDM ones so you might look into those. You should get new springs and retainers if you get new cams with higher lift.

Save your money and get the quaife LSD. it's cheaper than the JDM one.

Unless your're going FI the skunk manifold will probably hurt your performance. Someone told me that some company had an advertisement in grassroots motorsports magazine about a prelude manifold with individual throttle bodies on each runner. It would be better but probably costs an arm and a leg. Or you go go the route Billy went and get the ATR manifold if you could find a place to get it.

ECU swaps are a big topic right now. You could convert to OBDI or you could get a management system like the hondata, zdyne, etc one but those are big money. I think the Type S ecu is still over $1k so it's pretty expensive too.

All in all it's going to cost you a lot of money to do all those things (this is not a backyard project unless you don't want to drive your prelude for a few months). You ultimately have to decide if it's worth it or not.

Just my opinion though.

Why bother with JDM rings? US spec rings are just as good.

As for rods, just get aftermarket, you might be able to get aftermarket rods cheaper.

Type S manifold is the same as the US spec manifold from what I have seen (they both have dual runners). It's not like an ITR manifold.

Does Skunk2 make a manifold for the H22??

No one can reprogram the 97+ Prelude ECUs as of right now. The 92-96 Prelude ECUs can be reprogrammed by many people, though.

As for cam gears, I like Skunk2 or Unorthodox gears (I have Unorthodox gears myself).

Who is JRP? I have never heard of them. Most aftermarket pistons will require that the block be resleeved. If you want to avoid this, use Type S pistons (11:1 CR).

Crower rods are a good choice. I will be using Endyn rods.

Fidanza flywheel is a very good choice, that's what I am using as well.

I have heard of quality problems lately with the ACT. I have yet to witness it, but I have heard of people shearing the rivets on the friction pads. I am using an Exedy clutch right now, and I really like it.

The main restriction in the intake tract is the intake manifold. If you get your head ported, the manifold must be ported to take full advantage of the work. The head will flow much better than the manifold will support.

Are you talking about porting the exhaust manifold? Why bother? Get a Spoon, Mugen, or custom header.

VAFC is a good idea. You will have to fine tune the fuel curve after all these mods.

I agree, I love my Quaife!!!

Individual throttle bodies aren't very streetable as they kill the lower end, with a huge boost in high end power, however, it makes the engine quite peaky. It also requires an aftermarket ECU since it won't work very well with a stock ECU.

The Accord Euro R manifold swap is not a plug and play project. It's taking quite a bit of effort to do it, and I wouldn't want to duplicate the work unless someone was willing to pay me quite a bit!!

Hehe. I knew that it wasn't plug in and play but I figured if he was willing to spend that much money on other things, he be willing to pay someone to get it to work.

Oh, I wasn't contradicting you one bit. I think it will be worth the trouble, but it's a PITA to do!!

I think it would be worth the trouble too if I was building my engine. Can't wait until you get her back up and running. Although you are probably more anxious than I am.

Ya THINK!?!?!


Hopefully soon....I am really tired of looking at it, working on it, spending money on it, and not being able to drive it!!

I also have a couple of other "secret" mods in the work....
....we will see......
