i love steve kan's 7 it so kool man I wish ihad that car

 

hey greg wich one is better for road racing?

 

well It all depends on who tunned the car.. I know of 7 that was tunned buy Rp that had bbt-66 and only put down 400@19 psi 350@15psi, the intercooler had too much pressure drop and they tune to keep the motor from popping.. honestly I would rather have a greddy t-78 becuase lag does not bother me and I will run 25 psi a t the track..

 

gt35/40=quiq spool-up midium top-end
dual bb t-66=spool dont know (66mm comp is quite large)may spool slow but my friends say huge top end
my uncle has a turboII and he has a turbonetics t-04smething and it spools kinda slow but the car was
dynoed and it put out 467rwhp @ 18lb. boost

 

I really think that 35/40 will put down more rwhp at 15 psi than t-66 will ..

 

in puerto rico there r a lot of good mechanics like that dude tito racing and siguel racing puertorricans r the rotor genius of the world !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

how big is the compressor wheel on the gt 35/40(mm)

 

which one physically spins easier from spinning by hand or blowing on it? just curious.

 

wich ones better for about 18lb/boost street and 23-25lb/boost with vp fuel

 

what trim is good for 18-24psi
1.15a/r

 

what a/r will work better 1.15 or 1.0
q-trim

 

1.15 will have slower spooling than the 1.0. You will be happy with a Dual BB Divided 1.0 P trim , mated to a fully divided exhaust manifold. The GT3540 does spool quicker but cannot match the flow of a GT66

 

Here is a sum up

If you want good spooling but dont really care about making big power then the GT3540 is for you. Im not saying that its a shitty turbo, just small. The DBBs on a T3/T4 Turbo is good. This would be my only suggenstion. Never use anything thats T3 on your rotary engine ever. If you do choose the GT3540, go with a larger exhaust housing. The T66 is for steet kings. Big hp searchers and alot of drag racing. Running in 20-25 psi with this turbo is where is is comfortable.

Hey, I just noticed you are in PR, how come im mnot asking you the turbo questions. Go to quilles and ask him about the drag car,, cme back with some good info

 

curiosity and myuncle has a turboII and my father had a
1rst gen and when my uncle started moding his rx7
i got a ride and i loved it ,god it was so ******* FUN
iv been asking for one since i was 14...

plus i wish i had a 94-r2 with ahuge single turbo tha
can run the low 11ns on a 1/4 mile damn im making
plans and drawings already when i get bored
rx-7 loco man...

 

hey how about a 1.0a/r with a q-trim

 

what size port is good for that turbo

 

1.0 Qtrim will slow down your spooling but it also is a good turbine.

 

is the p-trim good for 18-19psi. my uncle says q-trim
is better for tat kind'f boost

 

Its not the boost that you pick the trim for, its the air flow. For the most part, you wont need a q-trim on a 2rotor. Add another rotor on, now you need a q-trim

anyhow, it would be a lot easier if you posted what kind of power, spoolup, pricerange and other things so we could give you the BEST suggestion for your (imaginary) application.

 

k thanks just learning

 

1/2 bridge ported ( standard ) 13b REW , T66 1.15 A/R P trim @ 18-25 psi for the street no BB though , what ya think ?.
