I just completed the Turbo upgrade of my beloved Z32TT.
I was reading the dyno result of my Z32 and decided to compare Z32 Vs. 2JZ-GTE SC.
They are totally different animals.
Z32 is more nimble and runs like a cheetah yet SC runs like a Bull.

SC is about 100 lbs heavier than Z32.
Z32 has VG30DETT, V6 with Bi-turbo set up (5 speed)
SC has 2JZ-GTE, Straight 6 with sequential turbo set up (6 speed)
Both cars are boosting about 18 PSI with stock internals.

In a way, this is an unfair comparison because Z32 is highly modified running aftermarket turbos, etc but boosting low and SC is running is a basic Supra TT with 6 speed and stock turbos boosting high.



Z32TT (Dyno2)
386 WHP @ 6180 RPM
347 TQ @ 4850 RPM




SC300 (Dyno2)
322.8 WHP @ 5737 RPM
340.9 TQ @ 4270 RPM

As the big boy boosting around 4K, SC pulls like there is no tomorrow.
I feel like SC pulls faster and harder than Z32.
However, speedo tells a different story.
I am going much faster in my Z than SC.

I have not had a chance to run them side by side so I do not know which one can out accelerate the other from 60 punch.

I think SC will jump on Z32 and able to keep up with Z32 from 60+ punch.

What do you think?

How is the SC 1k lbs heavier than the Z? My sc300 weighs 3,400 lbs.. it's not really heavy by any means.

Interesting comparison though.. A Z with a turbo upgrade barely makes more power than a 2JZ with stock turbos.

I thought SC is about 3700?
Z is about 3600.

Stock Z32 TT makes about 280 WHP on Dyno.
100 WHP+ a lot...

Then again, I can single turbo my 2JZ-GTE and make a butt load of HP.

hah- 1k = 1,000

I think you meant 100 lbs

Well, I weighed my sc300 myself (at a recycling center scale ), and it was 3,400 lbs flat (with the turbo/manifold/fmic installed too). I had about ¼ tank of gas at the time.

I just corrected.
Thanks.

By the way, I always thought SC is heavier than Supra TT.
That is interesting to know.

might need to correct again, you say that that the z32 is boosting low and the GTE is boosting high then you go to state that BOTH CARS ARE BOOSTING 18PSI.

Awsome Im surprised the TQ was so close. I think the sc wouuld win just from TQ.

I love the use of simile, but I do not understand exactly what you are saying by this. Can you clarify the driving chacteristics of the V6 that makes it Cheetah-like in contrast to 2JZ being Bull-like?

The 2JZ has a longer stroke and a midget for a first turbo, making it more torque-biased of the two engines.

From the dig the SC definitely looks to have the area-under-the-curve advantage. At 3800, the 2JZ is making ~300ft*lb to the V6's ~200ft*lb.

I guess I need to explain it better.

GTE has stock TTs boosting MAX @ 18 psi.
I heard some people running higher boost but 18 psi is high # for the stock twins.

My Z32 is capable of boosting up to 25 PSI (500+ WHP).
However, I have limited to to 18 PSI so I can keep my stock engine for a while.
-------------------------------------------------

If you are interested, here is the catch!

SC is has less HP & about same TQ as Z32.
However, SC is 6 speed, HP & TQ comes in earlier than Z32 and supposedly weights less?? (per Blk97SC300).

If you are a motor head, you will find it very intresting.

What is your opinion?

As I drove both cars at separate times, Z32 pulls hard but it's smooth until 6000 and then it put you back to the seat (burst) for a brief monent.
It's like Cheetah put herself into overdrive catching up with the dinner.

In other hands, SC runs like a bull.
It put you back in to the seat moment you floor it and don't let go until you let it off. The front end raises up and it's really loud.
I feel like I am in Cessna 310 taking off from runway.

clevercat

thank you!

TTSC3

Yeah, it's not really a good comparison based on the lb/min of airflow on each setup. Get the same turbo setup/same mods on a TT SC, then you can see the different dynamics of each CAR, not engine. Gearing, weight, will all play into how the comparison plays out, but you can get a simple comparison for the car itself, not really the engines.

You mean more power than a poorly tuned/running 2jz with stock turbos If you're running 18psi and only putting out 330whp, Mustang Dyno or not, then you got issues.

My hats off to the poster for having the patience to modify a Z32.
