I am getting ready for the upcoming season and probably wont be taking the GTO as much this year as I would like to get the Z down a few times. What will I need to upgrade in order to put my Z hard to work at the track? I currently have 433whp and will probably bump it up with a stroked forged bottom end and heads, FAST intake, tb, ect this coming winter. I mention this b/c I dont want to skimp on supporting mods for the current power level when I am planning on more power next year. I am already planning on a Stage II Differential with BOTH left and right hardened output shafts, HD Billet Pinion shaft support, 3.90 or 4.11 gears, and a Spec clutch. I would like to be able to launch hard on MT ET Streets and would just like to know if there is anything else I should upgrade while I have the car torn apart. I am still contemplating putting a cage in, and I know that I may eventually have to, since I usually like to go to Englishtown and they're strict on the safety equipment. However, this is still a daily car and I dont know if I really want a cage in it. I was also wondering about doing an aluminum flywheel, but was recently told that it may be rough for a daily street driver. Please let me know if I am over-looking anything. ALL help is GREATLY appreciated.

A 300M main shaft wouldn't be out of order. But this means the tranny has to come out. Launching hard on ET Streets is actually easier on the drivetrain than launching hard on drag radials. ET Street walls wrinkle while drag radials won't. The wrinkle eases the "shock to the system" a bit. I used to launch at redline on ET Streets without breaking much. Then again, I was only at 385 rwhp.

You won't need a roll cage unless you're dipping into 9s. You will need a roll bar if you run better than 11.50 which, judging from your mods, you most likely will. If you can't hit 11.50s with 433 rwhp, then you suck and you should immediately turn your car over to me :lol: :lol: :lol: Just kidding, bro. Let me know when you plan on heading down to e-town. I'm there at least twice a week.

Thank you for your response Paul, I appreciate your help. Also, thank you for the vote of confidence, now I know if I run an 11.50, I suck and will have to turn over my car, lol. Is the install for the main shaft you speak of difficult if the rear and clutch will be done at the same time? There are too many shafts I have to think about, lol. Im getting the left and right output shafts, pinion shaft, and now I have to think about a main shaft. Also, what do you think of the aluminum flywheel? Should I avoid it in a street car? Is there anything else I should look at upgrading to handle the stress of drag racing? Thank you in advance for your help.

May want to consider a dte brace. Al flywheel is also something I was debating. I think it will help slightly at the 1/4 mile track but may make the street driving more tedious. Ask around more, alot af varying opinions. The key is to get some seat time in before you go too big so you can get accustomed to the power and tires, IMO.

Rob, just curious if you have a roll bar in your car? I know you have run well below 11.50 and was just wondering if you have had any problems. If you do have a bar in, can you post some pics? Thanks in advance for your help.
