okay i really, really, really am sick of the stock twins...i hate them with a hate so deep i dream of smelting them into a huge honda symbol. i really want the TO4R, but i can get the T60-1 for a lot less....is it worth it?

Do you plan on running anything higher than 16psi? If so, the TO4R will start making more power than the 60-1 around there. I think the 60-1 is one of the best street turbos around. Makes boost fairly quickly and can produce some good numbers. 450rwhp at 15psi is very attainable on a side ported motor.

60-1 is the T04B?

not right away. so here is my question....with a T60-1 (without porting the motor...only have 42K on stock motor right now) and a tuned PFC what kinda power should i make on 15psi? and what kinda fuel setup should work well with this? i'm thinking cosmo fuel pump and i'm not sure what injectors would be necessary for the setup?

should hit 400 rwhp with the right amount of fuel. I don't recommend the cosmo pump alone though...possibly running 2 of them, or even running just 2 FD pumps is suffecient. I'd go with 1600cc secondary's.

I think i'm the only guy that has luck with the cosmo pump. Might as well go with 1600cc or at least 850/1200 because you will run out of duty cycle with anything less.

wraith 08-13-2003 08:57 PM

okay so twin FD fuel pumps...850cc primaries, and 1600cc secondaries should be suffient for 400 rwhp at 15psi with non-ported motor? would i be able to find any maps with this setup for the PFC?

IGY 08-13-2003 10:28 PM

Hell yeah! That's enough fuel for over 500rwhp. Doesn't hurt to go overkill on fuel. Now if you want to turn the boost up, you just turn the boost up! 15psi, 60-1, stock ports, very doable.

60-1 is from the T04B family and it dwarfs all of the other T04B setups.
