Well I just got back with my dyno results for my 98GT with said mods in my sig. Here is a pic showing torque and HP with fuel mixtures and RPM's. The Dynorun.001 was the baseline run with out the chip and tuning. The Dynorun.009 was the end result of the tweaking and tuning with the chip.

I was really surprised and happy with the results. No all I need to do is figure out how to get that power to the ground. :nice:

They are .540 intake and .540 exhaust lift with a 112 lsa duration. Sounds pretty nasty at an idle. The cams I ordered were supposed to have only 114 lsa, which give it a smoother idle, but they sent the wrong ones, so i went ahead and used the ones they sent me. I am not dissapointed with the decision to use them. :)

Very cool....where did you get your heads?

and did you do the install yourself?? if not how much did you pay?

I got my heads from http://powerheads.com/headswap.html, as they sell a kit that is a direct install. I did the install my self, which if I had to do it again, I would pull the motor next time, as I did it with the motor in the car this time. It took me a total of about 15 hours to do the swap by myself with the motor in the car. I could have saved myself atleast 4 to 5 hours by pulling the motor and doing it.

What type of DR do you all recommend? I have seen lots running Nittos and BFG's. Which of the 2 is better?



it depends on what matters more to you, hooking up, or durability. the nitto's have a longer life, but the bfg's are more sticky. so it's more of what you want between the two, than one being better than the other
 
Nice numbers! Cant wait til i can do the swap! As far as D/R's go. If you drive alot get nittos,but if it is just a weekend cruiser,and racer get bfg's. My nittos arent all that great and there 315's
 
Well the car is my daily driver right now, so I will probably go with the Nitto's.Do you all have a website that sells them at a good price? What would a set of 315's on 17" wheels run me? Just going to get 2 for the rear.
