ok so I got a 1997 Nissan 240sx kouki. pretty much bone stock with only 107 k miles came with a greddy td06-20 g turbo almost a complete turbo set up just missing the inter cooler and fuel rail. Is it safe to turbo the ka with stock internals. I'm aiming around 280 hp. I sold my is300 so I can get this car and have about 3 k left to spend. what kind of suppression should I go for? I'm not trying to slam it just nice smooth and low ride.

low boost is fine if you have a good tune. I would start by making sure the rest of the motor is ready to handle turboing.

Do a compression test and look into the timing set and see how its holding up. It probably about due for lower chain guides in the near future.

Supression or suspension?

Remember when you lower you are going to want to change out more than just shocks, struts and springs, to correct geometry.

Plus every answer has been answered a bunch on KA-T.org or here

My friend slapped a t3 on his bare block with a solid tune. He had detnation on 1 after a few pulls on the freeway. About 11lbs.
Honestly, its not wortg the risk if you dont have some good back up plan. First thing i would do, but subframe collar bushings for the rear end, cheap, and installs in less then 30 minutes. Next, clean that motor up. New sparks, plugs, rotor and cap, clean the pcv valve, injector seats, swap oil and trans fluid. Put 10w40. If you get coilovers, your gonna need adjustable arms all around if you want good fitment and grip, camber in the rear is bad lol. Whats your plans?

....are you saying 10-40 for the motor or transmission?

Because gear oil doesn't come in 10-40, and the KA takes 5-30, unless it's super messed up like mine and needs it. Unless he's working the crap out of it, I don't see why one with that milage should need anything but stock oil.

If you care about oil, check out bitog, and find the oil with the best specs and additives that you can, and a good filter, and run those. And get synthetic if you skimp on change frequency.

As for suspension, smooth and low don't usually go together, although I've seen glowing reviews of coilovers commonly held to be junk, from people who want low cars that their girlfriends like riding in. Maybe if you don't care so much about suspension, you should just get soft lowering springs, then you can use stock dampers (or even not stock dampers) and I think you can get spring kits that are not actual coilover packages, but do have threaded spring seats that fit onto your dampers, so it's adjustable. Then you can buy new and spend like a quarter the price of new coilovers. And 240's start out really freakin' high, so to look lowered is quite a drop, a little lowering just fixes how obnoxiously high looking it starts out.

And take the above advice, and get rear control arms at the same time as suspension, so you don't have to tear it apart again, like I do. The camber will be seriously and visibly messed up long before you're slammed. As in, you'll be accidental "VIP".

6-8 pounds is low.

Also why I suggested looking a the timing set before boosting. There could have also been other contributing factors in his set up. Also you could buy another KA and just start building it in the meantime for boost, while taking care of the important stuff to keep it running.

I don't want a gap in the rear and in the front a 2 inch gap would be fine. I just don't know what brand to go for. yea I found out the hard way on my is300 what camber can do to your tiers, I'm making sure this time I get everything I need before I lower it.
