I have been trying to figure out what I am going to do about upgrading the transmission. Right now the best option I see is from PAR Engineering out of Austrailia. With a group buy of 4 people I can get a complete set of Syncromesh gears and shafts for $4,500.

Question 1: Does anyone have any experience with PAR Engineering

Question 2: I only expect be running around 350Ftlb of torque, with this small amount of power is an upgrade even needed?


Info I found on PAR Engineering

Synchromesh engagement 1st~6th

• Ratios – 2.79, 1.80, 1.29, 1.04, 0.86, 0.72 (with std 1.11 ratio reduction drive)

(Actual gear ratios – 3.10, 2.00, 1.44, 1.16, 0.96, 0.80)

• Straight Cut to minimise thrust loads

• Modular main and output shafts for ease of maintenance, repair and ratio changes

• Super strong EN36C material

• All parts treated with advanced cryogenics and heat treatment processes

• All parts shot peened for maximum reliability

Optional Output Reduction Gears (1.11)

 

may i ask why you are thinking of this, think how many stock boxes you could buy for that amount

most people are using stock boxes or are you thinking of dragging the car ??

 

Yes, I know that is what I keep thinking. I was actually debating on purchasing an AP2 trans and taking the internals and having them heat treated and case hardened. I need to do more research on what the failure modes are before I make the decision.

I would like to take it to the drag strip, but I will only be able to make one pass at the speeds I anticipate so I don't anticipate doing much drag racing.

What clutch are you running?

 

i am still on my orginal ap1 138k box with the iron man competition clutch, just found out though it needs changing but it has 15000 miles on it so thats pretty damn good

 

thats a tough question, cuase it depends on driving style and use <read abuse> ur gonna give it.

you are approaching the power level though that stuff starts to break in gear

i would drive on the stocker until it broke and then decide if 800-1000 on a used stocker is worth it, considering its gonna break again, or spending the loot on a crazy swap.

 

if u have an f22...throw in an f20 and you don't have to worry about the tq haha

 

I ran a PAR syncro and dog box setup on my Subaru. I had no issues with the syncro setup, but I broke one of their dogboxes. That said, it was used and I have no idea how many miles or passes were on it, and I was learning how to shift a dogbox, so I wouldn't hold that against the company.

Seems like good stuff from my experience, and it's cheaper than the PPG stuff.
