efi lt1 going into a 79 trans am.

whats better twin or single and why?? i know one big turbo is better then two small ones, but are two small ones better for building quick spool up??

any pros and cons would be great, trying to decide....

twins on v-8's are sex.

can spool up two decent sized snails pretty quick. and sometimes easier fabrication to match.

id go with 2 saab 42/48s or possibly a pair of 48/60s

Twin y2k's is all you need, no problem spooling them up since you're running a v8 . If anyone else says otherwise, then you are dumb and gay : ). http://www.turboneticsinc.com/turbo_y2k.htm

thanks guys, i thought twins would be easier, then i wouldnt have to fuss with the cross over piping. but most homemade setups i see on v8s were massive single setups.


those y2ks look nice, but i think its a bit overkill, LOL 2000hp!!!


hotrex are you refering to this turbo:

On the LT1 I wouldnt go smaller then two T3/T4 hybrid ... I would even get to T4's
But if you got some money to spend get two GT30R's or bigger.

I think for twins, you do want the T3/T4 hybrids. You got an extra 50 ci on the mustangs. As far as twins or singles-maybe the grass is always greener but after making twins, it seemed that making a single would be easier (fitting the turbo in the engine bay, IC connections). But I would not have done it any other way. Two banks of cyl, gotta have twin turbos.

Twin T4s. You also want twin intercoolers.
