tribex Posted June 12, 2008 Share Posted June 12, 2008 (edited) does anyone know of these engines they are supposed to be a collaboration between tomei and os giken ??? i have seen a few advertised and am wandering about wether they are genuine or not?? does anyone know the sort of performance they give ??? twin t78s seems like overkill but i am after an rb30 conversion and maybe this is a better solution.....

Mr. Keets Posted June 12, 2008 Share Posted June 12, 2008 I haven't heard of such a collaboration but that doesn't mean it didn't happen. It looks like someone has just spec'd Tomei parts to fill out the OSG kit....it will be wayyyyyy expensive in comparison to an Aussie built 3L and even a R.I.P.S RB30 from NZ Link to comment https://www.sau.com.au/forums/topic/223558-tomei-osgiken-rb30/#findComment-3938871 Share on other sites More sharing options...

rb26s13 Posted June 12, 2008 Share Posted June 12, 2008 never heard of them beeing sold like that.. however if they did i imagine it'd be in the range of 55-60g for what they show there on that pallet it would be a farken monstor tho Link to comment https://www.sau.com.au/forums/topic/223558-tomei-osgiken-rb30/#findComment-3938984 Share on other sites More sharing options...

9krpm Posted June 12, 2008 Share Posted June 12, 2008 Collaboration????? Does that make things cheaper or more expensive? It looks like they just bolted some Tomei and Greddy parts to a OS short block. Twin T78 with max rev of only 9krpm won't work well.

STATUS Posted June 13, 2008 Share Posted June 13, 2008 It is a OSGIKEN short fitted with tomei filled head, not an of the shelf build. It would have been a cheque book motor tick all the best available options for its intended purpose.

9krpm Posted June 18, 2008 Share Posted June 18, 2008 (edited) Definitely the twin greddy t78 will not be very functional at the 9krpm redline they suggested. I've driven similar setup. The Twin T618Zs hit full boost at 4.5-5krpm. Single T04Z hits full boost around 5.5-6krpm.Twin TD06s hit full boost at around 6-6.5krpm. I am not sure when Willall's drag car hit full boost with their T67s. If I have to bet, the T78 must be getting full boost in the 8krpm....way too laggy. BTW what cams are they using on this setup and what is the asking price?

BTW what cams are they using on this setup and what is the asking price? single to4z on a rb30 hitting full boost at 5.5-6k rpm? thats not what ive read and experienced, on my own rb27 with the hks t04z, its making fullboost around 4300-4500rpm or so (that was on 22psi boost).

I knew I should have not mention this turbo coz I wasn't too clear. It might have been bigger. Full boost was in the high 20 and he had a Nismo cluster. All of the others that I mentioned were around 2 bars. What cams and intercooler have you got on your car?

9krpm Posted June 20, 2008 Share Posted June 20, 2008 OS engine with big drag cams. You guys might be right, it could have been a larger single. As you can tell I am not a real fan of big single. All I can say it's definitely laggier than twin t517Z and the twin T618Z Link to comment https://www.sau.com.au/forums/topic/223558-tomei-osgiken-rb30/#findComment-3960253 Share on other sites More sharing options...
