Ive heard that the T78 is a good upgrade from the twins. Im wanting closer to 400 Hp. Anyone here have the T-78? Is there much lagg?

vosko 11-16-2002 11:01 PM

i have a T78. its laggy but once you get on boost you better be ready https://www.nopistons.com/forums/pub...#>/biggrin.png

Turbo II 11-16-2002 11:03 PM

how much lag we talking about

vosko 11-16-2002 11:06 PM

if your not at 4k rpm or higher takes a second or two get decent boost

Turbo II 11-16-2002 11:21 PM

what kinda times are u running right now vosko? or you havent taken her to the track lately?

Viper1308 11-16-2002 11:26 PM

So Vosko is the T78 good for stop and go traffic as long as you keep the Rpms below 4K??

its fine in stop and go traffic. i had zero problems daily driving the car. its almost easier than stock because everytime you push the gas you DON'T get boost instantaneously....

Turbo II 11-16-2002 11:28 PM

im surpirised u didnt go t88

Viper1308 11-16-2002 11:30 PM

Hows the Garrett 35/40? I hear it spools better than the T78 and is not much more expensive.

Viper1308 11-16-2002 11:34 PM

Vosko what intercooler you running with and radiator. Im thinking of the FEED type 2 front bumper since its got a wide mouth. Will i have to have a front mount IC with the T78?

Turbo II 11-16-2002 11:58 PM

greddy 3row correct?

vosko 11-17-2002 01:12 AM

i have a greddy 3row and fluidyne radiator with stock bumper. no overheating problems even in traffic. i drove silver93T's car. its real nice. the T78 is laggier but seems to have more topend power....

1Revvin7 11-17-2002 01:39 AM

Is silver93Ts, the BB one?

vosko 11-17-2002 01:41 AM

silver93t has the GT35/40 BB

Turbo II 11-17-2002 01:48 AM

i was right :bigok:

Viper1308 11-17-2002 09:40 AM

3 row? Is that the same as the front mount? How do you avoid overheating if the intercooler blocks the radiator. Or is the 3row not in the front>?

Viper1308 11-17-2002 09:44 AM

What kind of performance are getting out of your turbo? From all your pics in your photo album it looks like Greddy included everything you need in the kit. What PSi you at and HP and torque. Sorry im asking all this stuff but im definently interested in the T78 or the Garret.

vosko 11-17-2002 11:18 AM

the 3row is in the front. i had zero cooling problems. i made 416rwhp & 319rwtq @ 13psi...... do you want better top end of faster spooling ?

1Revvin7 11-17-2002 11:40 AM

did silver93T ever get dyno #s?

vosko 11-17-2002 11:41 AM

he made 430rwhp @ 15psi.... hasn't redyno'd it yet

1Revvin7 11-17-2002 11:50 AM

Its hard to compare. When are u gonna dyno @ 20, 25psi?

vosko 11-17-2002 11:51 AM

maybe this week. i dunno LOL

Viper1308 11-17-2002 07:05 PM

Im not really sure, you say the T78 doesnt engage till 4K? I wonder when the garrett spools?

Viper1308 11-17-2002 07:18 PM

Where did you get your 3 row? Is it better than front mount?

1Revvin7 11-17-2002 07:59 PM

1Revvin7 11-17-2002 10:01 PM

I can't believe people still want to shop at rx7store.

That place blows. It takes about a month to get anything, thats if your lucky.
