Why stick with an NA KA? Just seems like a simple turbo setup is easier than NA after a point, and the cost is almost negligible once you factor in all the tuning you need on an NA setup to eek out that last 5-10 rwhp.

Because N/A is better! LOL! I personally wouldn't want to run a turbo motor in cali, especially if you wanna drive the car to and from the track. A big intercooler and a BOV is basically a big neon "PULL ME OVER" sign in most of so-cal. I think that is the reason that you see a lot of so-cal guys selling their SR's right now. Even a god damn exhaust ticket requires a trip to the ref and a full inspection. I wanna do a N/A KA just to prove that it can be done reliably and can produce sufficient power (200 whp) while still being "smog legal" (basically the bolt-ons will be carb legal and I will use a "stock" intake mani).

I saw that, but that does not mean that if you get a ref ticket you are off the hook. It means that you will HAVE to pay the fine. It's effed up, but that's the way it works.

If I was set on NA I'd probably drop a VQ35 in there. They've got to be getting cheap/plentiful enough to do the swap for not all that much money. Keep it roughly stock and it'll easily outpower any NA KA that will last for more than a few hours. And it'd be smog nazi legal.

Just my take on it.

The build looks like fun though.

This is my other thought. I have been wanting to do a VQ swap for about 4 years now. I am actually working on a guys car and we are attempting to do a smog legal vq swap. The only thing I am not doing is the wiring harness as it is super extra complicated. LOL @ smog nazis by the way!

On this same line of thought, what about a good custom SMIC? It would make cooling a snap, and a recirc. BOV is essentially silent. Get a quiet exhaust setup for at least the street and you're good to go. It'd be a PITA for inspections, but it wouldn't be that horrible to pull most of that junk off and get it smogged essentially stock.

Would be a pretty easy 300 rwhp capable setup if you put some thought into it.

My S13 with a stock SR setup with SMIC was pretty stealth, especially with the 4x4 stock suspension and steelies on it(swap happened early in its life with me due to a friend being a little "over zealous" when I let him borrow it).

No, I dropped the SR in it. He borrowed the car and killed the clutch and possibly the trans banging shifts for 3 days straight. Didn't even say sorry or offer to pay for the tow as he left my car about 30 miles broken down from my house.

It was not fun. Enough damage that I just decided to go ahead with the swap.

Na is eh imo.

I think Nitin only uses this car at the track PERIOD, anyways so why would he be worried about BOV.

I think it has to do with low end torque and throttle response for Nitin in this case

I know, I know.....You're a turbo whore. And a quite good turbo whore at that! LOL! I personally like the response, lack of complication, and of course the sound of a N/A ITB engine. Of course ITB's are NOT smog legal soooooo........
