that being said though would you say the exhaust sound would be louder or more calm with the turbo being at the exhaust?

use the OEM muffler and it should be as quiet as stock. No need to go larger, oem exhaust can handle 300~ horsepower.

that said, if you wanted to be "seen" then just remove the muffler. I assume you thought the turbo would terminate at the tail- it does not have to. You can install the turbocharger anywhere in the plumbing that you can find room. I would actually prefer it to stay away from the oem plastic fuel tank, but that doesnt matter because you can always fabricate a nice shield. lots of options.

I feel that it would still be fairly quiet without a muffler as turbochargers have a slight muffler effect. but there is only one way to find out. It depends largely on whether you keep the oem exhaust plumbing that leads up to the turbocharger as well. My idea of a simple, reversible, clean install would probably use the oem muffler's flange, such that I could hang the turbocharger on the oem exhaust hangers that used to hang the muffler. I could easily remove the turbocharger by unbolting it from the OE (muffler's) location, and re-install the OEM muffler if I wanted to. I've never done an rear mount before so I am not sure it would work or is even feasible however.

the turbo I would use
CT2-4447
Comp Turbo - CT2 4447 Billet
Its about $1800. The complete install would then likely cost $3000~ so you might as well do an SR swap if possible in your area.
For $4500~ you can install an S15 sr with a six speed including a fresh 3.4x differential with low mileage subframe arms/bushings etc... That would be my favored idea.
Use the OEM exhaust and an OEM sidemount- same effect, car looks stock ("ninja"). And theres your 280rwhp daily reliable for 150,000 miles.


Thus why I said, "if" I was going to turbo a KA.

When I first was sucked into the 240 world I thought like any other noob. And that was sr all the way. I was too dumb to realize that sr's were only "better" because they came stock turbo'd. I've learned over the past year of project 240's and reading on forums that a KA is the all around better choice. In the next month or so I will be putting a t25 on my stock KA. Patience is the key to the limited supply of A/M KA parts(which has grown since this thread started.) I picked up my internally wastegated t25 with a b/m KA manifold and sr turbo elbow for $175 shipped from the f/s section on here. Im going with the Megasquirt2 DIYPNP as a tune, and I don't plan to spend much more than a grand for all my turbo parts, not cutting any corners. I feel the reliability of both motors lies in the tune mainly. The SR20 comes stock with an almost perfectly tuned ecu, as the ecu's used for the KA-T are mostly reflashed and tuned to perfection. Your motor that is being turbo'd needs to be checked and have a few tests ran if you are expecting top reliability. Sorry for ranting but after reading four pages of comments I needed to share my .02 cents.

Bottom Line: I would love to see more aftermarket parts available to the KA world, and i'e noticed cxracing to be impressive on their more moderate parts- intercoolers, radiators, hoses etc. I feel along with more support for ka-t aftermarket product, will come more KA-Ters an will eliminate the price that I love oh so much for them. I also oppose the support of a/m parts because i love the d.i.y. custom style that rides with many KA's. It shows one of two things- someones got money, or someone know their shit. Theres my two cents for ya

I just built an s13 SR for 500whp for pro-am. Next season looking at hitting 550whp with response with different turbo setup. Right now, Complete tomei valvetrain with ferrea oversized valves, all the headwork to support it, twin scroll 3076 setup, blended and port matched intake and exhaust manifolds, CP 87mm 9:1 comp, eagle rods, cosworth, acl, arp everywhere.......

NOW I feel as if I should've built a KAT -_- I ALMOST did but I was scared.

KA advantages
-no rocker arms
-high flowing head (flows more like a VE head, and with headwork even more)
-super low starting costs (you can score KAs for free sometimes.. lolll literally)

SR advantages
-more options for aftermarket support
-out of the box reliability and performance
-stock SR can push out as much as the tranny can reliably. perfect. Slap on fuel and bigger turbo tune it and get some seat time

If you're going all out build I'd say KA is way to go. It's a little heavier than an SR, buuuut I think it's worth the few lbs lol.

KA needs:
-rotating assembly balanced
-cheezy rods replaced
-forced induction friendly pistons (not comrpession ratio, ring land to piston face distance)
-bigger head studs lol (for 700whp etc) (rb26 ones fit with machining from what I've seen)

Anyone wanna buy my SR so I can build a KA? lolol
I haven't even broken it in yet! haha It's got like 30 miles on it.

How much you think a built SR would sell for with xcessive z32 conversion for s14? (just curious)


BTW guy above me, I'd recommend RS-Enthalpy. KA-T guys here have great luck with them, RS-Enthalpy tunes are spot on and super cost effective. We have a guy here with a GT35 setup with lots of custom fab and he's currently switching from JWT to Enthalpy. Even had a guy switch from series 2 AEM to enthalpy. Just food for thought.

im kinda in favor of eliminating the whole maf sensor idea plus I will be paying three hundred dollars and learning how to tune my own car. I am completely DIY crazy so why the fuck not? haha

Sr20det hands down

[Mikester]

I prefer the SR- not because I think it's any better; but because it's the only motor I really know anything about (not all that much- but enough to be dangerous lol).

[illvialuver]

When my set up gets going ( picking up the spare ka to build this weekend) it will have forged internals, whatever I can get from Tomei headwise, turbo wise, and with the money invested I will not even think of reflashing a ecu, I am just going to pick up an AEM standalone unit, and pay for the tuning.

[bc.]

all I care about is the DET part.

[miamiman323]

I've had a stock sr and then a stock block ka-t. After getting the ka I pretty much decided ill never go sr again. I love the torque of the ka and I never really was into revving the shit out of a motor anyway so the ka was perfect for me. Now I have a built KA with an HX35 for this summer and can't wait to do some driving. Hopefully it won't be too laggy or else ill go back to the t3t4 I had before.

I think it all comes down to whether you like a motor with low end torque or a motor that screams up top. All comes down to preference and driving style.

[240taylen]

I prefer the Sr over the ka because it's more power to start off with and could get a substantial amount more with a few mods. I have a s13 sr black top owned for a couple months now. I traded an s14 with a ka with a rebuilt head and my jeep for it. Anywho. I'm not much of a trader and I loved my s14 but I rode in the s13 at track for a day. On 13pounds stock setup. No problems the thing was a blast. But in all honesty it probably won't be too long until I buy another ka and hopefully boost it because there so plentiful here in the states and originally learning to drift with a ka it's a great motor! IV heard people boosting them all stock and being reliable as hell! Putting down Lil over 200.. on second thought that's about a stock Sr lol

[wussmonster]

SR all the way for me. As far as legality or smog goes, I just throw the stock cat on and drive to deq. Car passes every time.
