im looking at some peoples videos and they have a 3.1 stroker with a twin cam set up and twin turbo i was wondering how your able to do this? i seen on done by os giken with this model tc24-b1 i contacted them and they said they no longer make them so i was wondering would you have to build your own or is their any aftermarket parts to make it a twin cam.

 

Welcome to ZDriver!

Yep... that's the OS Giken one, which is so rare, you'll never see one in person.

In all reality, unless you have tons of time and money to blow, there are much better ways to make power than building a custom DOHC. If you do want to waste that time and money, several crazy engineering people on Hybridz have cut apart DOHC heads (I think from a KA24DE) and sectioned them back together to make an inline 6 head, then had custom cams ground. Unless you have your own machine shop to use at will, I would dare say a project like that would cost the common Joe Blow about $5k-$10k.

That's $5k-$10k that you could have used much more efficiently... Unless you want to spend
all that so a select few of people will actually give you the "wow factor" you paid for.

 

alright thanks for the advice and welcoming me (: so what other ways can i tune the l28 and is it possible to get about 300hp out of it or would i probably have to do a twin turbo set up or swap it with a rb or something else?

 

twin turbo setup on this car is relatively pointless, a single turbo is just fine, all 6 cylinders feed one larger turbo will spool just great! but yes forced induction is the only good way to make HP on these cars. unless you want to spend 10K on a robello motor that is naturally aspirated and pumps out 300 crank HP if your lucky. kind of a waste of money.

 

os giken is the only known twin cam production head, but its worth more than its weight in gold......



the KA twin cam set up is one off and was built by a machinist. to have someone else build that for you would be stupid in cost.

twin turbos on L6's are pointless 99.9% of the time.



you can get over 400hp with a 3.1 single turbo.

so dont over complicate it, theres no need too.

 

you can get that without even going 3.1 stroker. the build cost of a stroker i think would outweigh the cost of just a proper 2.8 build to handle more boost. but to each his own.

 

300 on a 2.8 is relatively easy, hitting 400 gets a little tricky


a friend is running a pretty badass stroker turbo and pushing 454hp


lol but hard part isnt making power, its having a drive train that cant take it

 

Why make this complicated. drop a vg33et in that bitch, have a half a liter more displacement, more torque, a motor you don't have to re-engineer and you can push about 5-600WHP on a junkyard long block if it's in good enough shape.
