Project Gen 3 STi - Impressions of the Turbosmart IWG75 and BPV
By Wes Dumalski
"Hey Bro, do you want to test some Turbosmart stuff?" The quoted text is from none other than Martin G from MotoIQ headquarters asking me if I would like to play with any Turbosmart products on our GR STi project. With this project still in the early and mild stages I first scratched my head wondering what I would be able to use and test. When I think Turbosmart I envision huge external wastegates on race cars and e-boost setups. Initially I wondered exactly what I could even use on the STi... Not wanting to miss an opportunity I perused their site and used their vehicle specific search feature to see what they had available.
Project Gen 3STi: Testing the COBB Intake with Some Anti-Bling
By Wes Dumalski
Welcome to WCOB radio... all Cobb Tuning All the time... OK so yeah... the last few installments of Project GR have sounded like the making of a Cobb Tuning radio station! Well quite frankly every time we get the car to a certain point power wise we talk to our friends at Cobb and they tell us we should "try the SF Intake, it's a trick bit of kit and you will love it..." OK so our arms get twisted and we wind up with Cobb's SF Intake and Airbox along with a slew of Cobb goodies to look the part. In this installment we will be testing the SF intake and airbox along with showcasing the e-tune possibilities with the Cobb AccessPORT.
Project Gen 3STi: Testing the COBB Down Pipe and Exhaust
When last we left off we were singing the praises of AMS and the Cobb AccessPORT, what we left out was the fact that on the way home from AMS we were already making phone calls for more go fast parts. Yes, I had been in the car for all of 10 minutes enjoying the new found power only to realize that more power was just a phone call away. HMM what should I do next? Easy, free up horsepower through less exhaust restriction. The call was to Cobb and it was to discuss the downpipe in particular. I honestly had no plans to replace the stock exhaust as I am a stick in the mud when it comes to loud street cars and quite frankly every Boxer engine with a fart can sounds like Project 200SX with a blown head gasket... (No really they do).
Company Profile: AMS Performance

AMS Performance... No we are not talking about the knock off CDM version we are talking about the original Automotosport hailing from Chicago Illinois. Truth be told I spent some time at the AMS shop last November and began working on this article. It should have been before your eyes long ago, I should have been able to belt out a piece regaling you with their amazing records in the drag racing, power output, and time attack worlds. I should have been touting their accomplishments in the EVO and GTR worlds. SHOULD is the operative word here. The reality was that I didn't want to write THAT article. Hell every AMS article talks about their accomplishments from 8 Second Evo's and GTR's, to one of the most dominant time attack cars in US history. And while those are the things that AMS is best known for NONE of them would be possible without a key ingredient. That's right I am going to brush those things aside and focus on what makes AMS tick.... PEOPLE.
Project Gen 3 STi: Testing the COBB AccessPORT
As it turns out owning a project car is not easy! First and foremost these are real cars owned by real people that pay for them with their own money. Life as well as vehicle practicality and reliability have ways of getting in the way of project car progress and/or completion. Take our Gen 3 GR STi project for example... We had had the car repainted, put back to stock all just so we could start fresh. OK so that is a total lie, the real story is that the previous project car was sold by the owner after blowing up it's totally stock motor on more than one occasion...

While awaiting the development of some ARK parts for our Project 3rd generation STI we decided to prep the cooling system in anticipation of the future installation of power parts. Turbo cars run hot and when being track driven most have problems staying cool, especially on our Southern California tracks which are mostly located in the desert. We turned to Koyo Cooling systems for one of their race radiators for our car.
