1. I installed a pop charger, but it ddin't help much throttle responds.
2a. Plan on getting a ssac header with 2" to help with torque or go 2.5"?
2b. G20.net - Forums <--- Do I really need this with the ssac? If so, where can I get one?
3. Bump timing to 17 or 19? Stock is 13 or 15 for these cars?
4. Would under pulley help on auto?

99 p11 has the smallest cam so 91 intake cam and SSAC header will make a nice improvement.


the RR auto is retarded slow compared to the 99 because of the extra cat on the exhaust so changing up the exhaust will help tremendously


^Updated the thread title, but I picked up a 2001.

Psshhh, it's a P11 and meant to be driven slow. Very comfortable 11 seconds getting to 60mph!

- I just felt like it's so slow that it made me feel unsafe. Cars are made to go fast for a reason at times, and sometimes you just gotta punch it and get out of the way, well I punched it, but I was still in the way. Plus the whimpy cup holder is not helping on my decision on keeping the car. The trans is an auto, but still a P11 trans with LSD, it should be able to handle a few more ponies I would think.

Gears are really long on G20's. Maybe an auto B15 trans would help. Advance the timing till it pings then back off a bit :shrug:

Get the JDM Center console. It has 2 cup holders and offset's the ebrake. the only thing i truly don't like about the P11 is the suspension.

My stock b15 auto trans took 10psi daily from a gt28rs (maybe 225wtq?) for over a year, manually shifting. Not sure where some of these "guesstimates" come from?

You'd be safe with a t25 set-up, IMHO.

And...get a Taurus cupholder...

APX Auto Parts SENSEN® 1481 Shocks, Struts, Full Set (4 Pieces)

^I've searched and these are suppose to be just as good, if not better than GR-2's. I'm going to give them a try. For $105 to the door, you can't beat it. LIFE TIME WARRANY and you can pay with paypal.

^This could be an option, but way to much trouble. I purchased this car to avoid mods, as I have two other projects, but look at me now. If the SSAC header doesn't do the trick to help the lost it has down low, I'll be forced to sell it. I can't amagine if I had 3 more people in the car taking full advantage of the touring features #yawn.

Walbro 255 and a T25 kit @ stock boos should work very well.

Keep in mind auto trans will have issues when you push more power too, I believe they don't like anything above 140wtq, don't quote me on that though!

Correction even VE swap wont make it all that much better.


Disagree

My 01 p11 with Neo VVL head swap
