So I'm new to the JDM car modification world. But I know cosmetics are one thing but I'm trying to look into performance upgrades. So far I'm looking into a Takeda or AEM CAI and Mishimoto or PRL intercooler. However, Im trying to see if there are performance upgrades aside from that such as coil plugs, spark plugs, e85 conversion kits, suspension (no stance nation for me), and if a Type R turbo upgrade would work for my car. I'm not trying to mess with the exhaust, so all the input I can get is appreciated.

Is your Accord a 6mt or CVT?

Intake = sound; HF drop in filter = performance

I don’t believe a CTR turbo will work on a 1.5t- and if it did, I’m not so sure that the powerband would be so great- this is a 1.5 not a 2.0....however, there are some turbo upgrades for 1.5t although if your CVT (like me) that may not be the best idea..

It is a CVT. Which turbo upgrades are there? Also are there power upgrades that would make me go faster than Ford Focus ST drivers?

Looks like you're down about 60hp and almost 80lb-ft. You could probably make that up (and more) with a tuner, intake, downpipe, intercooler (some will argue that it's not needed), and flex fuel kit but dunno how long your CVT will last...

Here's my 2 cents..
I have a 1.5 CVT and my cheap upgrades are going to be an economical cold air intake such as this one: AF DYNAMIC COLD AIR INTAKE Fits 18-19 HONDA ACCORD 2.0L 2.0 L4 4CYL TURBOCHARGED | eBay
I know the listing above is for a 2.0 but I've been in contact with the seller and a 1.5 version is on the way. This would be about 8hp and should work well with this upgrade: JB4 for Honda 1.5 / 2.0L Turbo
That upgrade would give a 33hp increase. Both of these will cost you about $550 total and are very simple bolt-ons that can easily be removed if the car needs to go in the shop for warranty related repairs. So approximately 40hp for $550 and these hp numbers are at the wheel. I've spoke to both manufacturers and have seen the Dyno-graphs.

Enjoy!

Nope- you will likely lose performance with an intake....zero chance of gaining 8hp— ZERO. Best for performance is stock box w aftermarket drop in filter.

Heat soak for one...from the piping used, to the open air element sucking in engine bay heat instead of outside air like oem

Air intake arguments aside the best bang for the buck is likely going to be a Hondata or K-Tuner. That would also be an almost required thing anyway to accompany intake/exhaust modifications as those would likely just confuse the stock ECU and it would likely cut performance.

There is plenty of other threads out there on the internet that would discuss the pro's/con's to a short ram (like the one linked above) vs. a cold-air intake. But still, all moot points if you don't have something on hand to tune the car.

My curiosity is where the weak-points of the CVT are. There must be a reason Honda has a different trans in the auto 2.0T's and my guess is that it's not able to handle higher HP. I don't think that simple bolt-on's and a tune will get the 1.5 up to the 2.0 #'s but, CVT could still give out along the way.

We should have some guys chime in that have tuned their 1.5Ts. I was doing some Googling and found this thread on the 10th Gen Civic forum. Hondata R&D finds limit of Civic CVT Looks like KTuner didn't say exactly what the limit is for the CVT (or if the Accord and Civic use the same CVT) but the engine will make more power than the transmission can handle.

Also, I can't remember where I saw it (here or on Reddit) but some user tuned* his car, removed the tune to take the car in for some warranty work, and the dealer was able to tell that the ECU had been programed. So just a heads up to those that use a tune, that you might not be able to hide that from Honda if you run into warranty issues.

I've been told by a reliable source that is true... even returning the car to stock tune when car is hooked up to computer at dealer "breadcrumbs" will be left that shows the ECU has been programmed.

The cold air intake I listed has a sealed box that contains the air coming in through the oem air slot. Just has way less restrictions.

The JB4 unit i listed above is a piggy back system that applies different fuel maps and timing curves independent of the factory ecu.

Even though it's a piggy back system the fact that it's changing fuel maps, timing curves, etc. over what is stock I would still be concerned about it showing up when dealer computer is connected. The computers on vehicles currently are much more sophisticated and collect a lot more data than the past. I'm not knocking any of the aftermarket tuners/tunes however it's prudent that owners be warned that anything changed over stock could be problematic if warranty issues arise.
