OS Giken stroker kit

This is a very exciting new product coming soon from OS Giken.

The stroker kit for L-series 6-cylinders will offer 85mm stroke and 88mm bore for around 3103cc capacity.

I have no pricing or other information yet, but I will post it up as soon as I know.

In the meantime Kameari do offer a similar set-up, using a modified LD28 crank to get 85mm stroke, 138mm conrods and 89mm pistons (29mm pin height) for 3171cc capacity.

The OS Giken crank will be a much more impressive item, most likely a full-counter-weight billet type, suited to much higher rpm. The conrods appear to be similar to the forged chrome-moly H-beam type in the OS Giken RB30 engine. I better stop writing now...

You sir, are a monster in the best possible way

much better than a 2jz hey jane 

This is FANTASTIC news! 

If everyone gives me some of their Ruddy Money, I might be able to afford them!

Um.... Ben where do I send my cheque ?

Yes back on topic - if this is like other OS Giken kit then it will be very nicely produced and top quality product. I am sure many zed fans would love to have some of the OS Giken kit that has been made over the years in their cars.

If other custom cranks are anything to go by I would expect to have at least $5000 maybe up to $8000 given how strong the YEN is currently.

To give you an idea the RB30 crank from OS Giken retails for $7700. The pistons are quite reasonable at $1400, not sure about the rods.

Show me the money! A brings back memories of building my engine. All the little things keep adding up till you get some rediculous total at the end. A total that had you known when you started might have prevented you from building in the beginning.

Rumor has it OS Giken are building 5 new TC24-B1 headed engines for 'special' customers...

30k a pop!

Yes, I already put my name on one. Unfortunately the rest are all presold to US customers

I was wondering if the 'Aussie Buyer' was you Ben!

Ok I am going to use my airpoints for a flight to see one of those heads installed on a zed

Here are the TC24-B1 heads being prepared. There are five for customers and one for a new OS Giken demo engine.

This is such a marketing scheme. So sad they aren't going to mass produce it.

Fu - it's not something that's going to be in big demand - not a lot of people are going to buy something like that...

Yes, I already put my name on one. Unfortunately the rest are all presold to US customers

So what will you be doing with you current engine Ben?

Yes, I already put my name on one. Unfortunately the rest are all presold to US customers

Am I allowed to hate you for your purchase? 

When its all done, I think I might stalk your car.......

Pardon me, my tongue appears to have hit the floor.

One day, one day... 

how r they made? from a billet, investment cast or something else?

you'd think for 30g you could get one machined yourself given you can rip the design from somewhere else (give me a head and i'll cad it up )

The originals were cast from a Wooden mould - so OS Giken must have repaired these as last I heard is that they were a little damaged from the last casting took back in 80's. However technology has moved on a lot so I am sure they would have repaired or replaced the moulds.
