would anyone here know if there is any kind of performance mods available for Acura's J32A2 engine? I've already done the intake, full exhaust, underpulley kit, and upgraded ignition that I made fit from an NSX
This wasn’t Acura’s (Honda’s) most popular engine, which is why I have had trouble finding much of a performance aftermarket for it. I’m aware of the Comptech Supercharger kit. But despite their HP claimed, it did little to improve the hard performance numbers.
I’m not exactly keen on stripping the interior either, because this is a nice car.

There’s a guy with a fully built J32 in his EM1 around my town, like.. built in every sense of the word. Lmao. So there’s a decent aftermarket out there.
I’ve seen forced induction (superchargers and turobs), but that’s a bit over of the budget for a daily driver. Stroker kits to fit the lower end of an acura 3.5L used to be available, but that is also going too far for my needs.
Would anyone know if any kind of ECU upgrades are out there?
Also, hearing “I know a guy/saw a gay/saw a car…” On here for the millionth time is a bit annoying.
I’ve been in the automotive industry for a long time, and know my way around this industry to find what’s needed. There any many parts available for the J series engine that went in the Accord, but many of those parts are not applicable to my car.
Is some sort of HonData ECU available for this vehicle? My best guess would be to do the whole intake/exhaust thing accompanied by a tuned ECU? Not too sure what’s available, just throwing out ideas.
Suspension, lighter wheels, and good rubber are always a great recipe for some back-road fun.
Headers are a must - I run DC-Sports on mine, allegedly good for 20+ wheel horsepower (I’ve had my former Prelude on a dyno - it made 290 to the crank on those headers with a 63 mm Tanabe exhaust - not ideal for big power - and a mediocre intake, so that’s saying something). Comptech headers seem to be the best option for power gains, but they’re expensive and hard to find. P2R or any similar thermal gasket for the intake manifold is a must-have (the manifold gets really hot - I’ve seen dyno graphs where K-series engines lost up to 6-7 horsepower due to heat-soak, the thermal-gasket replenishes this loss). A big throttle body (70-72 mil) would be nice, but you’ll have to port the intake manifold to match. Removing the variable-geometry butterflies helps gain a little bit (contrary to popular belied, this device is not meant to increase low-end torque, rather it helps gain torque during part-throttle operation). If you want to go crazy - install a J37A intake manifold, good for at least 3 hp (compared to a ported stock J32A2 manifold), but those things are mad expensive and hard to come by. And finally - get an AEM EMS ECU (they say that a Greddy Emanage can be made to work, which is a much cheaper option, the EMS costs about 1000 dollars, I think). I’ve seen 300+ wheel horsepower on J32A2’s with stock internals, with only quality bolt-ons a a tune. I’m going to installing a J32A2 into my Honda Inspire shortly - with ported intake manifold, 70 mm TB, deleted butteflies, thermal-gasket, 76 mm intake with K&N filter, DC-Sports headers, and stock exhaust (cat deleted). Not sure what this will yield, but I’m quite sure it will be more than my Prelude’s 290 at the crank.
I’m going to install* a J32A2 - sorry, didn’t catch that mistake when posting my comment. I have a good excuse for making mistakes - which is the fact that I’m not native to any English-speaking country))
