Hello all,

I just got a 2004 camry, 2azfe, 2.4liter with 5 speed manual transmission. The car looks and sounds decent. Has about 90k miles. There is no trace of oil leaking and other bad signs. Looks good and I am so excited.

I plan to upgrade power performance on this car. As the budget restricts, air filter upgrades, header and exhaust upgrades, port and polish, a piggyback and sparkplugs to iridium are only on my list that I can afford.
Can these upgrades get 200hp? :nerd:
Afaik, this standard is about 150hp.
What is the recommended open air filter for 200hp or more? :grin:
Do I need to change valves as I intend to keep N/A? Anyone knows the standards size for valves, in and out?

I will definitely share the updates later on. I consider this as a 45-60 day project. And any input, substantiated, will be very appreciated. Thanks!

Updated Notes:
- Will the exhaust duration that seems very low (220s) be the obstacle to get 200HP?

Welcome, and glad you are excited :) I am not sure you will get to 200hp with any mod, other than a different engine, but I'm not the expert there. I have heard others state the mod air filters do not add hp. I'd focus the mods to add performance in other areas, like better lighting, oil catch can, new pistons (if you go that route).

Thanks for the response. Whats oil catch can for? The thought of replacing pistons does make sense knowing the car has more than 90k.

I had the same experience. After upgrading air filter to my 07 corolla, I found no gain. Later some said that the vvti blocked the extra flow. Then after changing cam timing, there was a gain of about 3-4hp.

First week of April, the car is scheduled to have upgrades, including pistons replacement :) Thanks for the share.

The oil catch can will collect oil and such coming out of the engine. You place it between the PCV valve and where it comes back into the block. But unless you get a baffled can it won't do much. There are some nice ones out there. At some point I am putting a red one in my Camry, and a blue one in my Tacoma.

I have heard of it for long time now. One of the biggest problem this gen camry has. But overhaul or something to be able to clean the clogged holes will eliminate the problem.

Mine is abit more than 90k, but since the plan is to have the head work, old pistons must go to ascertain there will be no pressure leak.

Thanks for the response. Mind telling me why jumping from standard hp of 150s to 200hp is not possible with those mods?

I start to read materials about 2AZ and found that its exhaust duration is about 225 only. Is that the reason?0:)

The standard 150s hp to 2400cc is kind of low, IMO. I saw an increase in other cars, not camry though, more than 10% just from a freeflow collector and a piggback. Imagine if header is also upgraded. And when the big thing from porting come into play, 33% ((200-150)/150) should not be so amazing, I hope so :grin:0:)

Thanks, I see that point. But after looking the above link and the more extensive the work than on that link, I have a good feeling that 200hp (about 30-35% increase than the baseline) will be achieved, especially with the vvti. It's reachable I can't wait.

What's your take on the lightweight pulley? Seems like just a tuning thing. You know sacrificing a percent torque for an hp...

0:)

Everything is possible but at what costs? how deep is your wallet?

Simple bolts on will get you a couple HP. I don't see 50hp there without turbo or supercharging it. And with the block thread head bolt issue. I wouldn't bother without upgrading to studs and repaired block threads.

Concentrate on losing weight and reducing parasitic drag, and a good tuneup.

Header, CAI, intake manifold... are useless without tuning.

Carbon fiber hood, balance shaft removal, lithium battery, lightweight alloy rims, no spare tire, simple stereo, underdrive alloy pulleys, synthetic fluids... are some things to consider.

The estimated budget so far is about $2000, including the exhaust, porting and a piggyback. If the budget allows, I will get an aftermarket air filter and piston replacements. And reducing weight is a lot more expensive and inconvenient, IMO. In fact, I got a chance to discuss more with the garage, and they told me that there was also an option to have more power along with more efficiency, but with extra money for the bigger flow cat converter. A magnaflow cat perhaps? Anyone uses the magnaflow cat? Thanks!

Kind of a surprise to me that the garage told me the pistons were okay. No visible blockages.

Here the labor is not that much, do I need to replace the pistons then? (I feel wanting to, but thinking of the money that I could use to buy a magnaflow muffler and a cat converter instead of pistons....:headbang:)

@Javytech Welcome to the site! You may get some salty remarks from members about performance mods in particular as they can be difficult to pin down. Especially when dealing with the Toyota daily drivers as opposed to more sporty vehicles. While there are all kinds of things that can potentially be done, it often begs the question about why (or even really how) on some of these cars. Like @Pvt-Public says there are numerous posts about increases that do not deliver the data behind them to allow for other members to verify. We see it all around here!

Well, I'm automotive technician, and professor for 25 years, i known what I'm talking about. Money make the difference, or you pretending your engine runs whit cosmetic part. , internal, cam shaft, 12.to 1 compression is close to 220 to 250 depending of the ability of the programmer, and of course with a aftermarket computer, turbo run between 450 to 900 hp depending of the settings. You need a reacing mechanic. I'm available.

You’re funny. 21:1 you are deep in diesel territory. 900 hp out of a streetable 2AZ you’re just dreaming. Like I said put up or shut up. Quit spreading that could be, would be, guessing, un provable garbage and mis-information. But you’re right about one thing……anything is possible ON PAPER.
