KA-T Usage
As long as I have been on this forum I have never really seen anyone talk about using their KA-T for anything other than 1/4 mile. Is there something I am missing here, because I rarely here someone talk about AutoX or drifting. I am aware of the fact that the Iron block of the KA is heavier than the SR but is it substantially heavier so much as to throw off the weight ratios enough to make it difficult to track with? Anyone's input on this would be appreciated, thanks in advance and YES I searched.

Re: KA-T Usage
no, the KA and SR weigh about the same. the very small difference in weight (5lbs maybe?) doesn't affect the weight ratio at all.matt0941 wrote:I am aware of the fact that the Iron block of the KA is heavier than the SR but is it substantially heavier so much as to throw off the weight ratios enough to make it difficult to track with?

I would think the low end torque would be great for drifting. Rather then having to keep the engine near redline all the time.
AutoX might be a different story, I like to use high revs for a track car. I also engine brake quite a bit. But in defense of the KA, I've never driven a low revving stroker around the track.
I believe alot of the emphasis is placed on suspension when setting up your car. Granted, if you want a decent track car or drifter your going to want a turbine with little to no lag time. Which is different from setting up a purpose built drag only car.
All in All a 240 with the KADET could be setup to do all 3 well. It just won't accel in one particular area.

Pull out your A/C and you've most likely saved weight overall, not to mention better airflow to your radiator.
The stock manifold isn't light, and if your turbo manifold is a compact design and not cast, it will be lighter. The turbo itself weighs a little bit, but nothing significant.
The intercooler is aluminum, so not a big addition there either...same probably goes for the piping, which won't weigh much even if it's steel. Only things left are miniscule...BOV, oil lines, coolant lines

To me, bigger is better. It is important to size it well to the motor though. A T3/T4E is a pretty good all around turbo. But the turbine gets to be a little restrictive for my tastes at the higher RPM. My T04B works well, but If I had the option to choose, I'd look towards a T04E 50 Trim using the T4 On-center turbine with at least a .69 Exhaust A/R. But I have also been looking at the TS04(T-58) compressor. Both have a broad range in the 78% efficiency area for the KA, but the TO4E-50 starts boosting 1 bar in the 76% area, workes into the 78% area then back to 76% by about 6000 RPM. The T-58 wil start boosting 1 bar probably in the 75% efficiency area and then stays in the 78% island the rest of the time. It will probably stay in the 78% area as high as you can rev a KA as well. I had to make a couple of assumptions, to make these calculations, but I need to start looking at where the boost threshold will be as well. The T-58 compressor wheels is .304 inches larger in diameter and will have a little more weight. But using the same turbne specs as I am now and going BB center section may offset this enough that it's not going to be significant.
NSport, XS Engineering and F-Max all make a kit for the KA24DE. Greddy is working on one, but who knoews when it will actually hit the streets. They've been working on it for a couple years already. But the Greddy unit will be CARB legal. It's a rather small kit in comparison to the other kits though. And rumor has it, it may end up a bit pricey.
