was there ever a factory sr20dett motor? if so...

[Tsukiko]

i am curious about single-vs.-twin turbo setups. one honkin hairdryer, or two smaller ones?

im sure it comes down to power delivery, reliability, etc. anyone know about this stuff, or at least have an educated opinion?

[AZhitman]

Never a factory setup, but then again, I don't know why it would be...

2 liters is insufficient displacement to necessitate 2 turbos, even if they were small units....

true.

but in general, what say you to tt vs. t?

I say its completely pointless to twin turbo any small displacement motor. The whole point of having a twin turbo motor is so the turbo lag would be minumal seeing that the little turbo spins the big turbo (which most of your power comes from) so even if you added little baby turbos..and you boost to like 14 psi..its going to be no differen't then someone that swaped in an gt28r off the s15 sr20det.

I remember one time at a car show i seen a civic with a b16 with a twin turbo set up..probably the most dumbest thing i ever seen..wow hes making 7 psi with 2 turbo's.. one must be at 3 and the other at 4.

LAWLZ

oooh... of course.

makes sense, considering the only cars ive seen with more than one turbo from the factory are exotics with w-16 configured blocks.... i have seen RB26's in TT form.. was that factory? doesnt seem quite right having figured that out.

in case you're wondering who the eff put a quad-turbo setup on a w-16 configured block...

Bugatti. check out the Veyron. basically its a working prototype, never see it in the states... blah blah. amazing car though. 1000BHP+ w/ awd.

haha yeah man that car is sick. I seen it on top gear so god damn fast

you also forget about the bugatti eb110ss, quad-mini turbo configuration.

RB26's are tt. There was a Japanese company in HypeRev 98 s-chassis that had a tt S 13 in a S14. Looked cool. Looked like to baby CA T25's on it. LOL!

Usually the japanese sports cars with twin turbos (Mazda FD3S RX-7, Nissan Z32 Fairlady Z, Nissan Skyline R32 to R34, Toyota Supra JZA80, etc) have either two equal sized turbos (parallel) or one turbo for low and higher rpm/power. The latter are tricky setups with lots of vacuum lines. The sequential turbo work where under lower loads a single turbo is spooling, and as load increases the other turbo kicks in. If I remember correctly the RX-7 and Supra are sequential.

The Skyline, 300ZX, and JZA70 tt are parallel.

There have been SR20DET(T)'s and SR20DET's that were also supercharged. I think it was GP sports that made a 600+ hp turbo-supercharged S15.

Dead link.

[SpeedRacer1]

Link isnt dead, NICO automatically deletes wikipedia links appearantly. I just left a link to twin turbos on wikipedia.

[BLKTOPS14SR]

Yeah, the MKIV Supra and FD are seq. A freind w/a FD had nothing but problems with turbo's not working right.

Wikipedia would steal info from NICO and not give credit.
