CRZ motor, but basically a L15. Nice build up. Never really see this kinda stuff over here.....UK FTW!

 

..but, but, intake mods don't make power on the L15!



Very cool build!

I'll just leave these here too, from the article. Rotas with trimmed stock center caps and added carbon background. Friggin' sweet.

 

They picked up 2.x HP at the hubs = even less at the ground

Lord knows how much they spent on the Mugen bits for that small of a gain.

And, if they did not have a tuning system it certainly would be the same as no gain when the ECU dials it back.

Also, as I pointed out the first time this build was posted up earlier in the year.. that vertically mounted turbine shaft is a big no-no.

A Garrett rep gets wind of that and say good bye to any warranty the CHRA had.

 

I know.. just stirring it up a bit. Didn't know they had any on-board management to get those gains. I do like the added response of the intake. Seems to charge forward on throttle tip-in a bit more. Anyways, the CR-Z has a lot of work put into it, but I have no idea about the turbo config, but it sounds like they had to get creative at the expense of reliability.

 

"We can immediately see the unusual design of cylinder head that joins all of the exhaust ports together into a common port. This looks like a challenge from a flow perspective!"

They do seem to know what they're doing, though. Always surprising to find out this type of high-end tuning (port modeling? new to me) finds a market among people who have only $23,000 to spend on a car. Maybe people take the CRZ seriously in the UK, hehe

 

Spoke to Garrett rep today about that and he confirmed my suspicions.. if that thing doesn't fail outright it promises to be a smokey fucker with oil leaking past the turbine seals
