300th Cosworth Subaru Engine Completed!
Posted by Tyler Hara on Thursday, March 18, 2010Here is a photo commemorating the 300th Subaru engine built at Cosworth in Torrance, CA. The facility in Torrance is the Cosworth Performance Parts Center of Excellence, leading the conception, development, and manufacture of Cosworth's performance parts line up globally.
Every engine built here at Cosworth is given a unique serial number and it's specs recorded for future reference. When we came up on the 300th build, we thought it was an exciting achievement. These engines are built using brand new Subaru head and block castings. Cosworth components include billet crankshaft (optional), connecting rods, pistons, rings, bearings, head gaskets, head studs, camshafts, valves, CNC ports, dual valve springs, retainers, and high performance oil pump. Some might argue that there are more Cosworth parts in these engines than original Subaru parts!
You can tell the photo was taken on a Friday because Magnus is wearing his black "Badass Engine Builder" uniform, complete with flat bill hat. The very same hats are available for purchase in our online store here: http://www.cosworthusa.com/store/pc/viewCategories.asp?idCategory=6. The black shirts are actually the uniform from the Cosworth UK engine build shop. Magnus and Lyon were both sent over there last winter to help build F1 engines for the upcoming 2010 season. The same precision and attention to detail goes into every single Subaru, Mitsubishi, Nissan, and Duratec engine and cylinder head built here in Torrance.

EVO X Intercooler Upgrade
Posted by Tyler Hara on Wednesday, March 03, 2010Production of our new EVO X intercooler upgrade is in full swing. These will be a direct replacement for the 2008+ Mitsubishi EVO X's restrictive and inefficient OEM intercooler. A mandrel bent aluminum intercooler piping kit (available separately) will be released soon.
Subaru EJ25 Animation
Posted by Tyler Hara on Thursday, November 19, 2009Here's a quick animation I created while working on a 3D CAD model to analyze V to P (valve to piston) clearance with different camshafts at various angles of AVCS advance. There's some cool stuff you can do when you have nearly all of the parts of a Subaru EJ25 engine modelled in 3D CAD. This is just a quick animated GIF I threw together for fun, as the animation was not actually necessary to get the data I was looking for. I hope to put together a better 3D animation when I have a free moment, possibly even including valvetrain movement!
EVO X Parts - Inside Out
Posted by Tyler Hara on Friday, October 23, 2009Our in-house fabrication wiz has built an eye-catching display to show off our 2008+ Mitsubishi EVO X engine part offerings - a cutaway 4B11T engine! Following in the footsteps of numerous other engine cutaways we've built over the years, this brand new setup will make it's public debut at the 2009 SEMA show next week. If you're attending the SEMA show, stop by booth #20855 and check it out for yourself.
This engine is equipped with all of the latest high performance Cosworth parts offered for the 4B11T:
- CNC Ported Big Valve Cylinder Head
- High Performance +1mm Oversize Valves (Inlet - Stainless Steel, Exhaust - Inconel)
- Ultra-High RPM Dual Valve Spring and Titanium Retainer Set
- 2.2L Stroker Kit (Billet 94mm Crankshaft, Forged Steel Connecting Rods, Forged Piston Set, High Performance Engine Bearing Set)
- Ultra High Performance H11 Tool Steel Head Studs
- High Performance MX1 Camshafts

New Clutch for the Red Dragon
Posted by Tyler Hara on Wednesday, July 15, 2009We're in the process of installing a new OS Giken twin plate clutch in our Project Red Dragon 2008 STI. This clutch should handle anything we throw at it, and we plan to throw ~600hp at it with the stroker engine that is going to be installed soon!
I've had great success with OS Giken twin plate clutches used on previous projects. I've only used the solid hub disks before, the clutch in the Red Dragon has sprung hub disks. It'll be interesting to see the difference in drivability. Installation and driving impressions to follow...
Subaru Inlet Manifolds - Soon, VERY soon...
Posted by Tyler Hara on Tuesday, March 10, 2009Our Subaru EJ25 intake manifold has been in development for quite some time now. We had plastic prototypes running on our engine dyno early on in 2008. We first showed a prototype intake manifold at Subiefest last September and we had pre-production aluminum castings on display at SEMA in November. Here we are in the beginning of March 2009, and intake manifold production is finally in full swing! Look for the first production units to be shipping in the next week or so.
A couple shots of the manifold installed on our 2008 STI project car - "The Red Dragon"
Here is the manifold installed on a 2006 STI with rotated mount turbo kit.
Proof they do exist! Here are two racks of manifolds waiting to be hand blended in the porting room.
Steve is putting the finishing touches on this particular manifold. Each and every manifold is CNC ported and hand blended by one of our highly skilled cylinder head experts.
More manifolds sitting on the shelf ready to be boxed up.

Edmunds Inside Line EVO X Project Car
Posted by Tyler Hara on Thursday, January 29, 2009The folks over at Edmunds Inside Line have acquired an EVO X from Mitsubishi for long-term road testing. The eventual goal of this car is to build a streetable Nissan GT-R killer... for less money. They recently installed a set of our new MX1 cams for the 4B11T engine. Check out the links below to follow along as they build this EVO X into a streetable track terror.

Subiefest 2008
Posted by Tyler Hara on Monday, September 29, 2008Earlier this month, we packed up the Cosworth van with our latest and greatest Subaru wares and headed out to Willow Springs International Raceway for Subiefest 2008. Subiefest is the "largest all-Subaru motorsport event in North America." Those are their words, not mine. But I believe them! There was a huge enthusiast turnout, with all Subaru models well represented.
Despite the heat, people came from all over the western US to show off their Subarus.
Subaru of America brought out about a dozen brand-new 2009 WRX's for people to drive around the track for free. As cool as that was, I think the ice water soaked towels they were handing out were even more popular.
Checking out the Cosworth booth. There's one of those famous Subaru towels again.
Our cutaway EJ25 engine is always a popular conversation piece. It shows off our CNC cylinder head, camshafts, pistons, and connecting rods. The display engine will be refreshed soon, including a new billet stroker crankshaft and other goodies for the SEMA show later this year. Those Subaru towels were everywhere!
See those two Harman Motive cars at the front of the Modified Class time attack field? The ones that finished in first and second place for the weekend? Yeah, they both run Cosworth parts.
Castrol Syntec Top Shop Challenge
Posted by Tyler Hara on Friday, May 23, 2008We are pleased to have been selected by Sport Compact Car Magazine to develop a Nissan VQ35 engine package for the "Castrol Syntec Top Shop Challenge" engine building competition. We will be up against the other Source Interlink Media publications, along with their partner engine builders. See this link for details on the competition:
http://www.syntectopshop.com/Our engine will be a naturally aspirated, stroked, high compression, high revving VQ35 that we intend to wring every bit of 400hp out of. Based on preliminary testing with a stock displacement, lower compression VQ35 development engine (check out the cam testing video in an earlier blog post), that may be a very conservative target! The best part is, the parts developed for this engine will eventually make their way to production, allowing any Nissan 350Z or Infiniti G35 owner to build an identical beast of their own.
The Sport Compact Car Magazine video crew came through the shop for a tour and an introduction. Here's a bit of who we are and what we're all about here at Cosworth.
http://www.syntectopshop.com/sportcompactcar-engine-videos/index.htmlNow here's where we need your help. There is an online poll going for readers to pick which engine they think will win the competition. We need you to logon and vote for Sport Compact Car magazine. Within just a couple days of the poll going online, a few of the magazines mysteriously ended up with 20,000-30,000 votes each. I know we've all heard the old sayings like "if you're not cheating, you're not trying" and "it's only cheating if you get caught". I'm not directly accusing anyone of cheating, I would never make unfounded accusations! But I will say that it would be pretty lame if someone felt they had to cheat to win a popularity contest... http://www.syntectopshop.com/vote/index.html
