With so much discussion over the F20/22 lack of torque I thought it might be appropriate to ask if the K23A1 would fit in our cars. For those not familiar, the K23A1 is a 2.3L turbocharged iVtec 4cyl that resides in the Acura RDX and boasts 240hp and 260lb./ft.

I have read the "K" engines wont mate up to the trans. since they are inteded for FWD. I would assume this would be the case with the RDX motor, but if it could be somhow fitted, it would be a great engine for our cars even in standard form. I wonder if anyone has dropped one of these things into an RSX/Civic yet.

 

Hold on...O.K. never mind. I almost thought I was on Honda-tech for a minute.

Haha.

The K23A1 makes 260 ft lbs of torque because it is boosted. 260 ft lbs of torque is easily reachable with any off the shelf turbo kit. However, if you plan to compete in the WRC and need the all wheel drive system that is in the RDX then it may not be such a bad idea. Who knows, maybe Tommi Makinen will come out of retirement and compete in one. Can you say Ralliart S2000?

 

Well, I figured it would be a good motor with increased redline and a littel more boost. A good track FI motor since it wouldnt seem to need much work past stock trim. My initial thought was that Honda should utilize this engine in the S2000 replacement, with raised redline and closer to 300hp. I dont know of any turbocharged S2000's that are seeing concistant track use, other than funded professional race teams like C-West's TT car. I cant knock the F engines as I bought the car in part to have one, but after tracking it numerous times and driving it daily, it seemed like an idea to play around with. The F20's compression being so high and never intended for turbocharging seems like a disaster waiting to happen if I put a turbo on it. I guess the jury is still out on the Greddy kit.

 

And yes I agree, it is sad that there are so many closed minded people on here.

 

Well It would probably be an economically better choice to do a supercharged F22/20 if you wanted on track power and reliablity. There are plenty of people tracking s/c F series engines. Not many doing turbos though. :/

While swapping a K motor isnt a bad idea. I just dont think the RDX motor would be a good choice for the cost of fabrication involved. Who is to say the RDX motor is a better choice than a boosted Fseries for use on the track? If your going to go through the trouble of swapping a K why the RDX motor? Why not do a K24/k20 hybrid and really make some nasty power?

If your arugement is for the simple swap of an OEM engine, then by no means is such a swap simple anyways. So you might as well go all out or get out.

The F20/22 is fully fordged from the factory. you'd be surprised how much power it can handle when properly tuned and setup.

I personally dont think the Greddy turbo kit is suited for track duty at all. Probably the worst choice if you wanted a turbo kit for track duty. Have you seen a SINGLE greddy dyno with a smooth hp/tq curve? Or one which didnt have boost creep issues etc etc. I am not knocking the kit its just that it requires too much modification to get to a point i'd be comfortable taking it to a track. The greddy kit is not exactly a tune and go kit. Much less a bolt on and go. An InlinePro kit with a small turbo would probably be WAY better and much easier to tune.

 

If i wanted to do a TQy motor swap for NA track duty nasyness I certainly would swap an RDX motor. Hell no.

You know what would be an awesome motor swap for the S2000? while maintaining NA awesomeness? How about the 286hp Acura TL Type S engine? Imagine one of those bad boys with ITBs headers and exhaust. With some good tuning i wouldnt doubt someone could make 300whp and run a 7000rpm redline.

 

so u wanna swap a V6 into an s2000?

why not just put an LS engine?

Not saying that I would do it, but it's probably easier than swapping a transverse FWD engine into a rwd car.

 

Dat Boi,
What bumper is that?
