Question on Single Turbo Supras...

[RedFox]

I heard that Single Turbo Supras are pretty wild. Do they mod a N/A engine, or do they mod a twin turbo engine to get these single turbo supras.

I deal suituation, 6speed N/A SZ-R Supra (1993ish) with 1 big turbo.

Anyone know any information on this?

Cheers

a single turbo supra is typically a TT converted to siingle

the 1 you are looking at is def a TT converted, as n/a didnt come with a 6-speed

Its exactly the same concept as converting a GTR to single turbo.

[DJ984]

how do the "sequential" (?) turbo set-ups work exactly (ie supras)...

does it go 1st turbo --> drives 2nd turbo?

Appears that the norm is to turbocharge a NA engine.

6speed N/As do exist?:

Turbocharging a SZ is both a waste of money .. and won't give you the required results unless big bucks are spent. The TT engine is a monster internally, and quite different. You can pick up a TT Supra for under $30k these days, and the NA are often around $20k. To turbo the N/A will cost you probably more than $10k, and it won't be done that well. Its similar to turbocharging a GTS n/a skyline. Can be done, but do you want to bother?

My friend investigated it (and to him money wasn't even really an option), ended up selling the SZ and buying a GTR Smart

Afaik the SZ-R Supra came in 6 speed

but yeh, thats definitely a TT supra converted to single T

[Guest INASNT]

nige from ices performance supra is pumping out 495rwkw at 2.0 bar with twin Trust 20G turbos.

[SHUTO-BOY]

yea converting a non turbo to a turbo would be more expensive than just buying a twin turbo in the first place?

i guess with the 3 litres,its not too laggy,and the low down torque is good.

DJ984 - The twin sequentials use one small and one larger turbo. The smaller one does not have a wastegate and it runs out of puff somwere in the rev range (not sure were) and this is were the bigger one is already workin to take over. Very heavy and tricky setup so big single on a 3 litre which will support 500+ HP on stock internals is usually the path taken.

ok, fair enough... so they're both driven of 3 cylinders each?... (like a gtr set-up) it's just that one's small and the other's big in-order to have the best of both worlds (quick "off-the-mark" accelleration + top end power and speed)???

[hippy]

2 turbos .. 1 small one bigger .. the smaller one does most of the work ...

DJ, I think you'd find that both turbos blow into all six cylinders, it's just that they do it at different revs.

SZ = was the NA

GZ = TT with leather seats, cruise, active spoliers

RZ = TT with cloth seats, airbags and sometimes an active spoiler

RZ-S = was a TT with electric seats but none of the other toys

are you sure its a SZ-R and not a RZ-S? It's very expensive to turbo the 2jzge motor.

The cylinder head, camshafts, intake manifolds, and exhaust manifolds are completely different between the GTE and GE engines.

The intake manifolds are also completely different in design, and again the GTE versions will not fit directly on the GE cylinder head.

The GE engine was fitted with a distributor ignition system, while the GTE engine was fitted with the latest high output coil-on-plug ignition system.

As easy as it would be for the aftermarket, the factory Twin Turbo system from the GTE engine will not fit on the GE as the bolt patterns are completely different.

The Non Turbo Supra received two transmission choices, the four-speed A340 automatic and the five-speed W58 manual. Both can handle mild transmission upgrades in power to about 400 RWHP before problems begin to surface. ( hmm yours is a 6sp )

But then ive read

1996 - the 6 Speed manual transmission in the turbo model was dropped due to emmision regulations. ( so it is possible to have a 6spd before 1996 )

but then

1997 - Return of the six-speed manual transmission.

do dah

wrong .. the turbos are the same size.

Nice work on bringing this one up again. Gotta be wot i take it.

This is the 2j right not the 1j? with the seq set up
