so far my 2000 z28 m6 has pacesetter headers, spintech catback, deleted cats, asp pulley, stealth lid, SSRA, taylor 10.5 mm, ngk tr55's, ls6 intake, janzter TB, tsp 231/237 112 lsa, hardend pushrods, harland sharp rockers (1.7 ratio) patriot golds, jwis chain, nos nozzle kit, spec 3 clutch, well actually i just purchased the juice kit and i'm in the middle of the cam install. i was just wondering on what i was missing motor wise so i can run around a 200 shot. now i know i need a fpss and a window switch. and a bottle heater would be nice also. will i need to get bigger injector eventhough it's a wet kit? and should i get a bigger fuel pump also? should i get a tsp mail order tune? or should i get hp tuners and a wideband so i can self tune? does that all sound right? thanks guys

 

200 shot is pushing it on the stock bottom end , even thought many people are doing it.everybody brags thats doing that but you dont ever hear the horror stories to often from them now do ya?with 200 shot id say you need a forged bottom end and fuel pump.as for the mail order tune,DONT DO IT they may get it close but itll never be right, they simple cant moniter the car and what its doing unless you record it then send it to them, then your computer will play mail tag for alwhile. as for the injectors the stock ones are fine unless you change your mind and go with a dry set up. dont take what I say to heart because im no "expert" im the one with the horror stories.Ive learned the hard way, thats all and dont want anyone else making the same mistakes I did.good luck on the install

 

I pretty much agree with what everything smokeum99ta has to say. You can get away with that 200 shot, but things are going to become a real gamble at that point and your going to have to do things right if you want the motor to last more than a day.

First the fuel system is going to need some help. The best thing (and maybe the cheapest) would be to build a stand alone set up for your nitrous system. If you really want to try a pull fuel off the rail for a 200 shot you will need an intake pump, hot wire kit, and you are going to want to eliminate the stock FP regulator in the tank and put an aftermarket one at the rails running a return line back to the tank (racetronix makes kits for all this). If you don't relocate that FP regulator you are going to get a nasty lean spike when you first hit it.

Secondly tuning. If you have no way of tuning the car yourself via HPTuners or Edit, invest in a wideband (like the LM-1) and a timing tuner. Also pick up a Scanmaster if you have no other way of watching for KR. Those will probrably be your best tools for tuning fuel and timing.

Lastly, I probrably wouldn't be caught spraying a 200 shot on pump gas, I'd run atleast 100 or 106 octane.

BTW: The TR55s are not going to cut it, your going to have to go atleast to a TR6.

 

thats basicly what i figured. although my plan may change and i just might build the motor with lunati rot assembly but most likely rod and pistons witha set of heads
