I know that the 3.5 liter FWD and 3.7 liter AWD drive train will fit in the TL, and I know you can get the 3.5 liter engine in the 2G TSX, so I was wondering first what is involved in swapping a 3.7 in a 3.5 TL, and what is necessary to swap a 3.5L in a I-4 TSX, then hopefully see what would be necessary to put the 3.7 in the TSX, and possibly fit the AWD drivetrain to the chassis of the TSX. The mounting points of the 3.7L engine I assume would be different than the 3.5L, but would probably work with some fabrication. What are your thoughts on this?

I think the 3.7L swap is plausible but not the best way to go about more power. The K24 in your car is already a capable motor, and can be boosted to upwards of 350 horsepower reliably.

AWD swap is pretty much impossible, unless you've got a few hundred thousand lying around. SH-AWD is not just a part that you can swap out car to car.

LOL, buy the TL if you want that and have the money.

save yourself the money from swapping and just buy a TSX V6.

Benefits of a 3.7l swap is not only do you have 305hp to start with, you have the ability to twin turbocharge it. I'd say it'd be a hell of a lot easier to push 500+hp from that 3.7 vs. the 2.4. Maybe a bit more work, a lot of money, but in the end you'd have a balls-to-wall, fast as hell TSX, and the only one with a 3.7l motor. I like the idea. If I get an extra $12k, I might just do it myself!

Aman

You'd be amazed at what the K24 is capable of. I've seen more built K's than J's

Tannis

You are right. The K is an amazing motor. But it will cost you $15k+ to even approach 500hp and I'm merely using 500 as a general figure since I started out with it. Anywho, the other end of the spectrum is torque. Fours have never been good on low end power. If it weren't for a turbo add on, which is the case here that I at least am entertaining, then you'd still be at a complete loss to a bigger motor like the 3.7. I'm just saying, having a great base-platform with good numbers is usually a good way to go if you want power.

Considering the options and the costs, I'd swap out my 2.4 for the 3.7 any day before throwing tens of thousands of dollars into a 2.4l four cyl and still coming up shy. Just sayin, big torque + big hp on a smaller/lighter car = a freakishly fast car. The extra weight of the 3.7 is negligible at those numbers.

But hey, whatever floats your boat.

The amount of work to bring the 3.7 AWD to the TSX would be massive .
Just off the top you need 3.7 AWD drivetrain (front to rear , engine , tranny , rear diff with axles all around ).
now to fit this you need also new rear subframe and hubs ,plus fuel tank (to clear driveshaft), exhaust system, you also need TL AWD harnesses and ECU to go with it .

What I do think might be possible is if you already had V6 3.5 TSX , get the 3.7 long block and install . you still might need ECU but at least the harnesses are there .

its rayden

^ agreed.

swapping in a completely different engine and drivertrain will cost WAYYY more than a custom turbo setup for your i4. if you really want v6 power characteristics, then get a v6 car. this will be much cheaper than doing a swap of any kind. even a 3.5 to 3.7 swap might not be worth the trouble. i'd rather look at my FI options before thinking of a swap.

Aman

Again, you'd be amazed at what the K is capable of. Many of these things turbocharged end up making more torque than horsepower because of their long stroke. You could probably turbocharge and build a K-series for <$10k to give you 500 horsepower. This is a ballpark figure.

And doesn't it make sense to start with your own engine instead of dumping that, buying an entirely new engine and working on that?

EdKiefer

right, my comments were not even cost wise (you might luck out a junk yard) I was thinking pure work that would be needed and yes part list would be huge .

On K24 turbo or even V6 ,only way IMO to make it reliable is to also build the lower end (forged turbo pistons with good rods) . this way has better chance of lasting . Unless you just want low boost like 6-8lb, that might work ok with the CR in TSX .

its rayden

i assumed that you would be paying someone to do the work and not do it yourself. the work would be where most of the money would be spent.

personally, i'd love to see a modest supercharger made for the v6 tsx.

EdKiefer

Since there no PS pump above alternator I would think its doable there . Isn't there SC kit for Older TL

its rayden

i thought i saw something like that, but i'm new to the acura community, so i'm not too sure what's out there.

EdKiefer

here one ,its not right yr so ECU tuning probably one reason .

Edit: Thats a lot of cost for 65hp .
