So it's been quite a long time since I did any engine upgrades to the Accord, and I'm starting to get that itch again.  I feel like I've hit a wall with bolt-ons, and kinda ran out of ideas.  Was looking for some things to do, as I still have a "to-do" list for the car, but most of it right now pertains to maintenance and brake upgrades.  Below is the list of engine mods I have so far (just copied and pasted from my profile... don't over-criticize some of the items).

ARC high-pressure radiator cap
K&N polished Typhoon Complete Cold Air intake w/ Drycharger filter cover
DC Sports 4-2-1 2-piece ceramic header & generic double-walled flex pipe replacement
Custom A'pexi WS II exhaust w/ 2.25" stainless steel cat-back piping, Magnaflow 18” Magnapack straight-through resonator & generic 12" Turbo Pak high-flow resonator
2004 Acura TSX intake manifold
Power Rev Racing K24 thermal intake manifold gasket
Optima RedTop 75/35-925 high performance battery
A’pexi Super Ground Stabilizer
Unorthodox Racing Ultra SS underdrive pulley kit (crank, power steering & alternator)
NGK premium laser iridium spark plugs
Mobil 1 5w-20 synthetic motor oil
Royal Purple Purple Ice radiator coolant additive

Any other ideas?  All I can think of right now that I don’t have is like a throttle body spacer, but I’m not even sure if those do anything useful.  Mind you, the car’s an auto so I’ve never had the intention to do crazy engine builds or involved internal upgrades (unless it’s something fairly straight-forward and beneficial), and I’m not too fond of extended down-time for upgrades because I actually want to enjoy the car this summer.  So, anything I can invest in that I don’t already have??

Forced induction. The easiest one would be nitrous but you'd need tuning, obviously. What do you have in mind?

Enjoy it for the summer, save funds for car parts and upgrade during the winter. MT swap maybe? It all depends on your price range and what you actually mean by a "performance" upgrade.

K pro? You already have all the bolt ons why not optimize there performance.

Realistically, there are only a few options to go from this point. K Pro and cams come to mind. I'd also get rid of the slushbox too.

Z - Forced induction on my 4-door automatic?  Meh.

Tim - I already have the funds actually, just not the time or technical expertise yet.  As for a MT swap, to be honest, my take on that mod has always been rather than going through all that trouble, I'd rather just buy a car that's got stick off the lot.  As far as cams, that might be possible, but I know you can't just throw those in and call it a day.  So in comes engine management with K-Pro I guess, but see my thoughts below.

Mike - With what little bolt-ons I have, would K-Pro and the price associated with it, including the tuning, really yield that much more power versus the money I'd have to shell out for it?  Prolly not.

Summary - I know, I shot down all your ideas.  I'm a dick.  Feel free to critique.

Honestly, what we have under our hoods, except for Tim who has nothing under his hood :D, is crap. Were I in your position, the two options I'd be looking at are:
1)MT swap and hang a snail off the back. Surprisingly, our stock long blocks hold up rather well to some boost.
2)Full TSX swap. Honda reliability plus guys are pulling some decent numbers out of a stock K24A2.

Number 1 is my personal favorite as that is what I have in mind for later. Besides, like you said, FI on an autotragic is meh. You're absolutely right. It is. Either one of the two options I laid out obviously require K Pro to run them but you already knew that.

My point is this... Any mods your going to make going forward are going to require tuning so why not make your next mod a tuning solution.

Mike, take a look at my revised post.

After my post... Biter!

Dave, the reality is that with your AT you're just not going to want to make big power. What Z said is true to a point. Our stock motors can handle a good amount of boost, but eventually oil is going to get past your rings. I've found that TSX blocks to be a bit better anyway. I even know a guy that's selling a TSX long block and transmission that I could pick up for you.

Mike is right though. If you're going to do anything else, get kpro. You may want to contact Nikos at SVM and see if he's making cams for the econo VTEC motors. I know he's already making 3 lobe VTEC cams and single lobe and dual love VTEC killer cams.

Nope. I was in the process of editing when you posted.

Z, don't you already have a manual?
 
If cams and tuning might make sense as a next step, than I need to do more research because I only vaguely understand what cams do and what the risks vs. rewards are for that upgrade.

Thanks Mike for the tips too.

And Tim, killer cams?

 :rofl:

I do. That's why I have a slight advantage towards that first option. Were I in your shoes, I'd choose the first option. Mmmmm, boost.

Boost is something I would not choose for a higher mileage motor. After I put the sc on my original motor, it was spitting oil out the tail pipe. I have also seen the exact same thing happen on another high mileage Accord that has been boosted. Yes, boost will make power, but the Life of the motor will be drastically reduced.

Dave, VTEC killer cams basically get rid of the low speed (economy) VTEC love on the camshaft. Basically, VTEC is always kicked in yo. It isn't something I would suggest. The reason why I brought it up is because he does custom cams for K Series motors.

If you want to learn more about what cams do, hit me up. I'd be glad to explain. If you want kpro without a dual ecu harness, let me know. I can help you out with that set up too.

True. I plan on picking up a spare block anyway before I boost. I may just boost current motor while working on the spare. Anyway, I derailed the thread a bit.

Dave, your car needs some love under the hood since you've hit the bolt on cap. I've got ideas as well as everyone else that's chimed in but ultimately it falls on you to decide what's going to happen next.

Yep.  But boost will reduce the life of ANY engine, be in higher mileage or not.  Mine's still under 80k.  Then, if I swap to a MT, I'm assuming I'd need a MT ECU to go with it.  As far as K-Pro, to be honest, I'd rather have one that allows for the dual ecu harness option, unless my other choice was a good deal money wise.

^ I think Alex still has an AT ECU after his 5spd MT Swap.

You don't need a MT ECU actually.  If you were considering KPro, there is an option that you can use the KPro ECU without the dual ECU harness, and it would work out to being about the same price if not a little bit cheaper than running the dual ECU set up (considering everything you need to get to have it work properly).

any updates on this build?

Nope.  I wasn't doing a build, was just getting ideas from others as I'm stuck with mod upgrade ideas.

imma try the Ralco RZ lightweight stock diameter pulleys next. just ordered a set.

What did they run you?

$199 + bloody shipping  :(

Ouch. I can imagine the shipping to you being absurd.

Likme everyone else has said, the next best mod is tuning capability, preferably KPro. Now for your AT I would also suggest a nice beefy B&M external cooler and start re-training yourself to lift off the gas when the transmission is up shifting to the next gear, this is when your trans is most vulnarable to damage from extra power that future FI or other internal mods would cause. Now as far as FI, pushing 5-6psi from a SC would give you goos reliability (with tuning) and some nice added power,as other have said another nice route would be a K24A2 swap, the internals as sooo much stronger.

i just installed a Long Tru-Cool tranny cooler (Part #4451) last week in time for track day. i noticed the cooler gets really hot pretty quick. now i FEEL i did my tranny a huge favor.  :D

i don't plan on doing FI, i just need a wee bit more power (i reckon about 10more hp) so i can finish on the podium in my bracket. (i'm about 1.8 secs off on a 2.06" lap time)
