  • 927 Intercooler
  • 604 Front Strut Bar
  • 210 Motor & Trans Mounts
  • 279 Shift Kit
  • 607 Cam Kit
  • 650 Sti Gauge Kit
  • 150 Floor Mats
  • 110 Titanium Shifter
  • 110 Pedal Set
  • 450 Control Arm Set
  • 1900 Differential Kit

AVCS?

Well I have a few here, Struts, Springs, Head Lights, Wheels, oil cooler. These are just a few of the things to add. The conversion cost of the tranny alone is around $14,000 just to give you an idea of the costs. That is what it cost the subaru rally team to upgrade the Group N WRX tranny to the 6 speed.

Aha, can't believe I forgot the seats! The tranny cost seems extreme though. What would a replacement cost for a stock STi tranny in Europe?

Keep em coming guys, this is good stuff!

But wouldn't you rather have the real thing?

STi, there is no substitute!


Maybe STi stands for:

Synthesis
Technically
Impossible

exhaust
toll card holder (beside cup holder)
switches for headlight, IC mister etc...

The stock Brembo caliper and pads cost a lot more than that. More like 2 grand.

Waiting looks like the best way to go... and if the plan is to go crazy with mods... then the 2002 2.5RS sounds like a good enough platform. Guess I'll have to wait for Vishnu's kit in January to see what's really up

Your list is great, but remember, you dont price the entire part. All you can count for the price is the difference between the stock part and the STI part. So the total will be substancially smaller.

Dont forget the cost of the 05+ knuckle for the better front wheel bearing and 5 x 114 bolt pattern. STi brembos on the wrx knuckle = No Bueno.

Oh dont for get a set 5 x 114 of BBS rims, new will cost around 4k and used about 500-600$

In my option, sell the wrx and buy an sti, even if it has to be used one, it will save you alot of time, money and frustration in the long run

It's cheaper to buy an STI than convert a WRX over to one.

I agree...I tried going the conversion route, it's such a waste of time and money.

Insurance is actually cheaper on the STI than the WRX and also a converted WRX will not be worth as much as an actual STI. So it's a deep money and time pit to convert. Just sell the WRX and buy an STI.
