I am thinking of down the road adding a KB 9psi intercooled to my setup and wondering what mods i could do before then that will be compatible with the charger and add hp now...other then the bbk hpipe and AT catback that i have already planned on...any help dont wanna waste any $$$

 

[02GTKB]

gears, exhaust, shifter and thats about it

Built short Block, head work, control arms, brakes...

If you haven't already, can the shorty headers and spend the money on a set of LT's and accompanying mid-pipe. You'll see more power out of them that you ever will with a set of shorties. Shorty headers were build for no other reason than ease of installation (and emissions purposes, depending on where you're from). From a horsepower standpoint though, most of them flow marginally better than stock manifolds at best.

Otherwise....start saving your money for some beefier engine internals and some headwork.

If you are serious obout the kb just save up and get it first. you will be much more satisfied, and then you can nickle and dime the small mods later.

 

[JTAM963]

but every1 says i must get the shortblock first for it to be safe on the engine otherwise i would get the KB now...id rather not blow my engine though?? What about getting a new shortblock 3500$$ then new xhaust 800$$ and then what??

 

[JTAM963]

is it true you need to build the engine before the KB or what...what about going with a 6psikb and then modding the engine with full out KB parts...???where would that get me??

 

[2001sleeper]

if you rely on the KB tune then the short block isn't long away. there tunes just have too many complaints. if you get a good tune and respect your ride, you shouldn't run into any problems. get the 9psi IC kit. you'll save time and money in the long run instead of getting the 6psi kit.

 

[JTAM963]

what would every1 think should i get the shortblock first...itll put me back like 3500 bucks...and then does the shortblock come with new heads and cams or what..then get exhaust and save for the big daddy KB...i think thats my best bet...so im safe b4 powering up??

That would be your best bet. Some will say it’s not needed, but it’s a well known fact that the stock short block internals suck. People who advise against it either A Don't even own a supercharged vehicle, or B Don't own a supercharged vehicle that they've put very many miles on since the install. Doing it right the first time, will prevent you from having to tear it down and do it again in the future. Especially if down the road you decided you want to get greedy with the boost.

For the most part I agree with 2001sleeper, just get the 9psi kit and respect your car. Most people that blow there car on 9psi is caused by them not installing everthing right or do not know how to drive a car with a kb like, going 65mph in 5th and holding it to the floor, I dont care if you have forged internals or not you are asking for trouble. As far as the tune alot of blown motors are form someone f ing with the tune and they dont know much about kb blowers, leave the tune how it came and drive the car. I run the ***** out of my car on 9psi with stock internals for 12k miles and not one problem. If you have the money to have forged internals then go for it, if you don't just be smart and the motor with last a long time.

IS there anyway around not gettin a shortblock and still building the engine to be able to hold at least 400rwhp?? What would my AUTO gt with kb9psi really make with just american thunder catback and stock Hpipe??

My friend works at kb and he said that you are ok if you stay below 450 at the wheels. I would say that your car should make 370-380 rwh. It would be like 395-410 rwh if you had a 5 speed.

 

[JTAM963]

I was also adding the xhaust too..would i be able to down the road still swap in a shortblock once the supercharger is already in anyway???? I know itll cost me tons of $$ to install both...but what has any1 paid for either installation

Or C They see no reason to give up the miles you have left on a perfectly good stock shortblock. It is going to have to be rebuilt at some point, but you might have 5,000 or 50,000 miles left on the stocker. I just don't see a need to throw money away till you need it.

Now, I am also a big fan of not repeating work either, so if for some reason you have the motor out, might as well do it then.

You can't really blame their tunes. I run a modified copy of their tune on my car, and I can tell you that it is very conservative with timing, and is set up to command a flat 11:1 a/f ratio under wot. The people that are having problems with the tune, more than likely having other issues that are effecting the tune. Examples would be undetected vacuum leaks, bad sensors, bad gas etc. A dyno tune is still a good idea, since it should either uncover the problems or tune around them.
