a trap of 140+ with the th350......thats great!!!!

I so want to do this swap. Is this the same car racing the 300zx with a rb26, 20psi and 75 shot of nitrous???

that might be the 1st 9 second rb25 powered vehicle in the states!!!

If you read the thread, it gives a breakdown of exactly what he is done. I think its a 125 shot.

It might be the same car as the one racing the 300zx, not sure. I do know he is friends with a guy who drives a 26 powered z32.

Most use the Nitrous to spool the turbo and get the car out of the lights. The Rb does not make enough tq on a Big turbo setup.

Yup the nitrous lets him get up off the convertor and have the turbo spooled very fast. Otherwise a high stall turbo car is fairly laggy on boost alone. Also the nitrous cools the combustion temps alot.

Antilag is good for a stick car but then you deal with consistency problems. You also put alot of premature wear on the turbo from the combustion occuring to spool the turbo up. Its fine for a track only car but for quick consistent times an automatic is still better. Believe it or not but the nitrous is probably whats keeping his engine alive for so long with the 67mm turbo.
