GOALS FOR V3
A very reliable and drivable platform that I can cruise around with and take to the half-mile events when I want. First and foremost I do not want to give up the drivability of the car as I take it to work every day in the warmer months and make weekend trips frequently.
I am not upgrading the turbos just yet (unless someone wants to buy my existing set). The built motor/trans will allow me to have the peak power I have now across a wider rev/gear range, without fear of damaging the internals.
Got this from Joe at AIM Performance on Friday night
The K24/20s are probably the best bang for the buck upgrade I've seen in relation to turbos (assuming you're starting with a X50 car). They respond like stock K16s with almost no lag, they hit hard and can hold all the way through the rev band. We were actually presently surprised when we saw the final dyno charts.
I'm able to cruise around with them barley going into boost if I want, or downshift and get going. At WOT they are hitting my programmed boost limits around 4,000 RPM.
The exhaust is a quad resonated X-Pipe built by FabWorx. They also plumbed the external waste gates dumps to plumb right into the exhaust system.

That exhaust could be hung on a wall as modern art
Unfortunately I am K16 car I do want to go the upgraded K24 route... it is going to be an uphill battle on that.
I only made 4-5 1/2 mile runs so far, all in the high 150 MPH range. The best being 160 MPH. That is on 5 gallons of E85 mixed with a 1/8 tank of 93 octane and launching the car in 2nd gear.
On the OEM transmission, 1st gear is gone in a blink of an eye. I was also experiencing issues with engaging first gear over the past year, which was compounded by me changing the transmission/engine mounts the day before the event. The transmission build and longer GT2RS gearing should help significantly, along with the stronger engine internals allowing be to ramp up the boost and experience more torque.
On 93 octane/E85 mix the car ran a best of 156MPH in a roll race, with a verified start speed of 56MPH.
CSF Radiators will be keeping us cool all summer long! Figured after all of this, I may as well address the 14 year old cooling system before it becomes an issue.
Everything is coming together and we are in the home stretch! I'm excited and nervous (in a good way) at the same time. I should see it roll off the trailer at the SlipStream Half Mile in PA this weekend.
The engine is back from Tim, the trans is full together (after a slight delay caused by waiting on a fresh r&p and custom 4th gear from Guards), the new turbos from Precision are here, CSF radiators are being put on as we speak.
Today Prodigy got me hooked up with the newly ProEFI compatible BTI Gauge as well.
VFC - very cool!
Really looking forward to reading about the results! Could you post some more detail on the trans build?
BTW, since you are talking to him - ask Tim why he stopped posting here or on 6spd... Miss his valuable input.
Here are the transmission details:
New rear main seal
GT3 Cup retaining plate
997 GT2RS Mainshaft
997 GT2RS 1st, 2nd, and 3rd gear
Gaurds custom 4th gear
CMS Billet sideplate
New ring & pinion
Wave trac differential
Other random bits and pieces
I haven't been communicating with Tim directly, I've actually never spoken to him outside of the forums. AIM Performance knows him well and have been managing the build. To my knowledge his posting slowed down due to a very busy workload at both his day job and the Porsche stuff (he is not really a full-time Porsche builder, just very knowledgeable and very talented).
