i'm doing a cosmo swap for a buddy and his funding is on the tight side, so i was thinking about using the stock twins from the 2 rotor cosmo...

anyone know where they peak out at hp-wise? power goal is very conservative right now...~300ish whp. fd twins would hit that no problem, but i recently sold my spare set because (all together now) "i'll never use them" d'oh!!!

so anyone running the stock cosmo twins, what kinda power you making?

 

dunno, but I have a spare set of Cosmo twins on the shelf

 

i asked the same question, but no luck.

 

I would like to know too. I have this setup, the only problem is that my clutch is slipping when I'm under boost. So I don't know yet how it pulls. I hope to get 300rwhp on my ported RE with stock twins.

 

well, i'll post up in a month or two when i find out then...

 

I hooked mine up, then I ran lean so I had to put a new fuel regulator and I also put my 1600cc secondary's on. I was tuning it and it was really pulling strong, but my stupid oil seals in the turbos took a crap so I shut the engine off. I'm currently trying to buy more for some members on this forum. I'll post some hp numbers using a g-tech pro once I get them back on. It will be a few weeks, just hope it doesnt snow.

 

cool.
we've decided to go ahead and use them. i too, will post some number when i get some.

 

Sorry guys, but I won't be giving any hp numbers from these turbos. I thought my turbos were damaged so I installed another set of cosmo turbos, but a seal in my engine has failed. Its time to rebuild and slap a GT-40R. I'll still follow this forum, Im curious on the hp numbers I could of had. Good Luck everyone.

 

no worries. we'll see what kind of numbers i can come up with.

 

Shouldn't the stock cosmo twins perform fairly close to the FD turbos, or are there a lot of differences between the two?

 

Theres a few subtile differences. Mainly differnt compressors. I have 2 sets of 20b ones...

 

i've always wanted to build a manifold and use the 20b turbos on a 2 rotor.

 

I can't wait to see your numbers guitar.
