Its getting to the point that I am thinking big picture beyond bolt ons for making some after market juice out of the old a3. I dont have a true allegiance to either fi or na, have kicked around a k24a2 swap as those have come down in price and seem like that will mate well to the a3 tranny and other components. I am even keeping an eye out for Chunky's updates on his custom cams and mapping.

I am looking for the biggest bang for the buck with the best reliability, as this is the DD. I will have the car for years to come so can be patient putting things together, but I need a direction. Thought about the k24a2 with a sc, keep the whole engine oe, but wasnt sure how well that would work with the higher cr. I dont need a million horsepower, 225 whp would be fine 250 whp would be great 300 dependable whp would be awesome.

So if anyone has any "big picture" ideas that they KNOW will work really well, feel free to offer up your suggestion.

thanks

 

nitrous is your answer.

The obvious solution I was missing.......

Anyone done the k24a2 swap?

 

https://honda-tech.com/zerothread?id=1216312 K24A2 Swap into an EP3.

 

stock motor= nitruos + big *** turbo

swap
k20a2 = turbo or na
k24 all motor

 

You don't need nitrous. A stock A3 with a properly tuned turbo system can net you 300whp, no problem.

How reliable would that be? It would seem like a lot of boost would be needed to hit 300 whp out of the a3????

In general I would really like to know about set ups you guys have already done and know of. The swap Lucid Moments is doing looks awesome, a k24a2, really has me thinking about that direction. I could stay NA with nice bolt ons and k-pro or add the SC like he is and make silly power. Cash would be the only limitation.

I have considered doing the whole k20a2 swap, tranny is really nice, but would this hold water compared to the k24. I mean I know they both make 200, but doesnt the 24 make like 20 more ft/lbs? Not to mention the potential upside with the SC. No replacement for displacement afterall.

Of couse whatever direction I take the set up must make reliable everyday power, the car is my dd. So let me know what you guys are using in real life in your cars.

Thanks

It should be quite reliable in fact. Apparently, the general consensus is that 300whp is the max the A3 can do safely, too. It's been done by a few different people on ephatch.com at around 10-11 psi.

And with all due respect to Lucid Moments... from what I've read, boosting a K24A2 and revving it up isn't the best idea in the world... that extra stroke is punishing on the rods.

Damn, How'd I get in here.

I'm not planning on going much if any beyond the stock rev limit by the way. 7100 should be plenty. I don't really see the need to push past that. If at some time in the future I PNP and build the bottom end then maybe, but that will probably never happen.

He said biggest bang for the buck, not biggest hit to the wallet for mediocre gain.

I just read the word Toda and my credit card starts to shiver!!!

I have to do things in stages, wife would KILL me if I spent $7K on a swap, sc and all the goodies that go along with it, but if I could pull off a simple swap this year for $3500ish I may live until next year to add to it. Of course I also really want good reliability so I am leaning towards a k20a2 or k24a2 swap this summer, with i/rh/e/Hondata. Either one should get my whp into the 200's, both are straight forward swaps and with a good donor the engine shouldnt give me any trouble.

Now I just need to decide which swap to go with???

I repeat... he asked for BIGGEST bang for the buck! That's boost, pure and simple. No disrespect to the all-motor scene, but the words "natural aspiration" (which is properly abbreviated as "NA", not "N/A") and "bang for the buck" do not belong in the same sentence. Ever.

 

sorry if i hurt you

??? What are you on??? I simply took to task why you bothered suggesting all-motor based on the initial poster's requirements. Hell, I even went out of my way for you to know I wasn't trying to bash the all-motor scene. Sounds to me like you just can't admit you're wrong on this one.

Like squeezing blood from a rock.

I say N02 is always the best bang for the buck.

 

This year will be a swap to start with, I keep thinking more and more about just going with a k20a2 or k20 complete swap. I mean the whole thing just bolts in doesnt it, tranny, ecu and all? The k20a2 tranny comes with a lsd doesnt it?

Anyone know how much for a complete swap?

Thanks

The K20A2 is pretty much a straight swap in. It doesn't come with an LSD though. Not sure how much they are going for these days.

DC5 ITR LSD will run you about 400 bucks from a reputable vendor on eBay. That's the downside, though... they can be tough items to locate. Aftermarket ones like Quaife cost around 850, but that sucker has a lifetime warranty. I'm not sure about the other brands, though.

Thanks Phil!

So I find my lsd from an outside source. If I had a k20a2 engine, tranny and ecu would that bolt straight into my car, '05 ep3? I know the '05's had an ecu change, but with a2's ecu would the issue be emilinated?

Any need for axles or other components or will the ep3's just bolts up?

Thanks

 

The 05 RSX-S had an ECU change, I am pretty sure the EP3 ECU's stayed the same. Because of that I would try to avoid an 05 K20A2 just to be on the safe side.

 

type s uses a k20z1 with a different ecu.
