what are the pros and cons of automatic and manual transmissions?

Yeah if you have a 5spd ecu and can spool a large turbo like that on the line..Either swap in 5spd ecu or get an eprom ecu, chipped..

Yeah thats true, but i have decided to go full stand alone AEM. Let's see how that will work or DSMlink. IPT does have a modified valve body for us, thats what i have in mine.
The whole negative Auto opinion of some people that like to shift can change, when you see how mean the launch on an auto is. I do not look at parasitic loss as an issue because enough torque will get you down the track, not to mention the launch makes up for it. It can be a bit expensive, but rebuilds wont be an issue for a while. There are external problems that 5 speeds have such as breaking axles and wasted clutches having to drop tranny for. All in all everyone has their niche

The power potential and consistency is great with a great spool up off the line. Im going with a new setup this year with a Gt35r. Im really curious how that will spool up, i might need Anti-lag and nitrous.

I hope you turned up the boost on that 16g to at least 22 psi before switching to a 35R..You will HAVE to turn up the boost on that 35R, 18 psi ain't gonna do it...I have had both, still own both turbos..I wish I would of had my Meth kit before I took off the Evo 16g..My IPT re-stall had no problems stalling it on the line..
The GT35r is another story, still loads of fun on the street, just don't ask it to spool up on the line...

so I still have decent engine braking.

What smaller diameter converter are you referring too ? I've been checking the junkyards for a possible smaller diameter converter to improve stalling on the line..

Just go to the track and observe. All the fast cars are auto.

Convertor tech might have been posted elsewhere. This is my quote
The 10" convertors put into 1g/2g autos for racing etc are not std
They are donor casings with our stator/spag etc machined to fit
The 10" can be modded to 4000+ rpm stall for big turbos, cams & no nos
Our 11" from memory can be modded to 3500 rpm stall max I think ?
The 11" slips less above 4k than a 10". Meaning more efficient on fuel & times
I'll probably get shot down for this but, an 11" with nos beats a 10" without
Cheers !
