Man this makes me want a LS V8 over a KAT in my S13 again :-/
When I jotted down on paper how much the kat setup i want will cost me, and the end result that i will get... i still feel ill be disapointed of spending the money i would spend.... so I keep thinking I want the LS1 V8 instead :-/
It will cost me about 8000+$ to get about 400lbs/ft and 400whp reliably that will last on even daily driven abuse, depending on turbo and cam setup and other factors... all built up block and and head... but that would be it. The upper limit.
After that running much much bigger turbos would make that low end go away (eg; getting 600whp), then even if there is low end, its all lost at top end and then again not much of a rev range despite being a 'small' 4 cyl.
All the power and power band that the kat produces can be used differently but i want more than one thing... high top end, high low end, good long power band, etc... I mean a built setup with lots of low end could be used in autox, a built up big turbo engine with high end for drag... but i want both haha.. not possible...I would be kind of restricted to 400~ range with everything imho to still retain a good low end...
400whp/400ft-lbs/tq is just the beginning with a more or less stock LS V8 with a few mods. Imagine slapping supercharger or Turbo on that.. damn lol, it would rip the rear end no doubt, I doubt even 335s would suffice.
So LS V8>super built KAT and i think itll be cheaper in the long run, reliable heck even better on gas with the T56 6 speed ...
The kat is such a funny motor with its torque always slopped either towards low end and no top end or with cams and big turbo only top end and little to no low end :-/
When I see LS V8 torque curves.. theyre so damn flat but then again obviously its a big v8..
Another thing with kat is... add a turbo/IC/etc... and you make the already heavier than SR, KAT be another 70lbs more. I don't want to offset more weight to the front...
LS1 is NA = ftw... etc...
I don't know this seems ever so tempting and damn.. it has like... infinite space lol! Seems like MORE space than a frickin KA stock in the engine bay to me! A KAT is so crowded... the turbo nearly sucking in the mbc lol (at least with top mounts and bigger turbos haha)
I don't have AC, ABS, and soon I don't want to have the heater crap either (stripped car). This seems just the right thing for me.. so tempting oh man...
Congratz on your build up man.. its absolutely fantastic...!!!!
This thread makes me want to build an LS S13 so badly...
Sorry for long rant, got me quite excited + I'm working night shift, but almost going home... im bored LOL.
