I bought a 13B-RE and I will rebuild it very soon. I would like to know if it's worth to port it ? How far can I go before hitting the water jackets ? As far as a TII housing ?



Thanks!

depending on your hp/reliability goals, porting maybe optional or a must. it's hard to answer all your questions in that they are somewhat subjective. post what your planned setup is and also check around in the faq section. also the single turbo section might help you figure out what turbo setup is needed for your wants if you haven't already decided.

Sorry I was talking about end housing.



The setup I'm planning is:



- stock twins (12-14 psi) for now, maybe a single next year

- haltech e6k

- 1600 cc secondary

- FD fuel pump

- 3" exhaust

- FMIC



Maybe I forget something. I guess it will be around 250 rwhp



So porting or not or just remove the rough ?



Thanks for help!

stock twins? fd fuel pump isnt fd fuel pump stock https://www.nopistons.com/forums/pub...IR#>/smile.png

umm stock twins at 12-14 psi is much more then 250 with bolt ons

get a bigger pump?

djgiantrobot 03-19-2004 01:34 AM

it would be going in an FC, so FD fuel pump would be an upgrade for him. The stock twins on a cosmo are smaller than FD twins, but 12psi is probably still going to still be a bit more than 250whp, get the 255 walbro.

It's going to significantly more than 250 unless something is seriously wrong or you like wasting gas (i.e. running rich).

-Ted

what would you consider as significant? 300rwhp?? on 12 - 14psi



is that kind of boost level reliable for the cosmo twins, or will it wear them out a lot quicker???



cheers

Does anyone know what boost response is like on the cosmo twins running in non sequential mode. The reason i am asking these few questions, is i have a set of cosmo twins sitting in my shed and i am thinking of fitting them to my daily driver which can be seen in my sig, and want to make sure it is worth it first https://www.nopistons.com/forums/pub...IR#>/smile.png



any help appreciated



Lance



ps i don't mean to be hijacking your thread dude!

FD3S_wanted 03-19-2004 09:58 AM

djgiantrobot: FD fuel pump is not good for about 350 rwhp ? FD guys do not change their injectors before changing the fuel pump ?



RETed: I'm happy to hear that it's going to be more powerfull, I just wanted to be conservative.



cach22: I don't care if you hijack my thread cause these are good question that I wanted to know also.



So what kind of port should I do for this setup. Wild or mild ??



Thanks for inputs guys, I appreciate!
