Turbo Upgrade Kits

[mr2ya]

i here you
td0 anything is not for me
how about that.

[mr2ya]

1st dyno is good, did have good trq curve
just not enough topend (for me)

How about a T78-34D making 200 ft lbs by 4200 rpms. Though peak torque sucks, but it's reasonably so given the size of the turbo.

ok but
how about gt35r makes 200lbs. by 4000 rpm
before only starting to slope down at 8000 rpm
making 588whp
those mitsu greddy turbo's were designed oh about
15 or more years ago
things have changed
there is reason everyone wants to swap to GT series turbo
NOT just a kid talking ****
31 years old I've been around
seen it all

Unless this is specific to a 3SGTE, this is apples and oranges...

Here is a typical 35R on a 3S

200 by 4250

And if your example is pertinent to this platform to make direct comparisons, care to give any details on said car and uncorrected dyno jet plot?

I've yet to see any definitive experiments showing DBB centers showing improved spool over a properly sized, journal bearing turbo. Transient response for on and off throttle definitely feels better, however.

[mr2ya]

are you really saying bb turbo spools the same as
journal bearing turbo by any brand. WOW
was ats dyno and yes was 2.2liter
these are all bad examples because
the goal for me is flat not peak horsepower
and i would not pay $2000 for a turbo kit that while looks good
strugles to make 400whp (by strugle i mean 23 or more psi)
and just does not spool the same
there only 2 reasons for buying greddy turbo kit
1. you want a simple bolt on street legal kit (usually not much trouble)
and most common!
2. To say you have a greddy turbo kit

there are few people on this site talking of replacing
there t76 or 78 whatever it was to a GT35R
way dont you ask them way

not bashing greddy, by any means
damn good boost controler, and other small greddy parts on my car
friend has 350z with there turbo kit. is damn nice
BUT YOU KNOW WHAT
A PR. of gt28rs's (disco patatos) or 2871's WOULD MAKE EVEN BETTER.
LOL

[mr2ya]

This is like leaf springs vs. coil springs
i mean come on

[mr2ya]

potato

[mr2ya]

i know my spelling and all that sucks. but.
my point was,
for $2200 or less
you could have a gt30, gt35 something.
and if so why get an outdated TDo6, T67 etc.
of course you luck up on TDo6 kit cheap or used
by all means get it.
not saying its a bad kit but,
that there are better 4da$.
not downing TD06 owners.

Are you trying to suggest that Jeff's dyno is not a flat powerband? Looked pretty flat to me...?

?
There is a reason why companies sell multiple kits using various turbos. The td06/05's are not a 400whp daily driven turbo, it'll max out at around 430-450whp...it's just too small. The same can be said for a gt2860rs...each turbo has their purpose and powerband.

None of the greddy turbo kits for the mr2 are CARB legal, all of them replace the factory cast downpipe+cat assembly for a tubular downpipe without a cat.

I wouldn't go that far, the greddy kit is a POS. What you said earlier was greddy turbo, which IMO, are not crappy. They are cheap, and thus far have performed just as well, if not better than a similarly sized 3071R.

There are many reasons to change a turbo...I don't understand how this plays a part into this discussion? I love my td06, and even I have contemplated piecing my own 3071R setup just because I want something new and different...

I guess we will have to agree to disagree on every aspect talked about thus far. Personally, I think Greddy products are junky and are the bottom of the barrel as far as JDM companies go. But I think the turbos they use, MHI, are great performers, even if they are old tech.

And just for references sake, only two of the four dynos I posted are ATS Tuned. 370whp gen3 was tuned out somewhere in the north east, and Jeff's setup was tuned by Bryan Moore.

And the 370whp td06 spooling 200 by 3.7K was on a 2L

What i'm saying is, a turbo's ability to spool on any given motor is greatly dependent on it's efficiency, size, and how well it's mated to any given setup. Not whether it has ball bearings or journal bearings.

[mr2ya]

ALL THIS AND YOU SAY GREDDY IS JUNKY NOW
holy crap, you took alot of time telling me how good
they were, only to say there crappy
nearly every dyno i 've seen show
they just dont spool the same
just dont make same topend power as equel sized other
any brand turbo even non BB models
1st dyno sheet you posted did make more trq sooner than i had
seen before using this turbo (TD06)
anyone can set there cams up to make more lowend or topend power
notice how it losses power on the topend.(THE STOCK TURBO LOSES POWER ON TOPEND ,WHY WOULD BUY A AFTERMARKET TURBO THAT DOES THE SAME THING
a GT turbo on this cars setup would surely make more (never seen one person ever lose power by changing to GT series, allways made more. EVERYTIME)
WHy are they changing turbos
if they were not so good i doubt people would go to the expense and effort

every turbo has its place and job.
use TD06 for doorstop
its just more functional

cant wait to see what i said wrong this time
lol

[mr2ya]

GT series has new blade design
not just an addition of BB center
i bet the old TD0 line was designed in the late 80's.
over two decades ago
TD06 in anyway shape or form does not compare to GT3071r
few people will take on that case mr. cochren

Do you have trouble with reading comprehension?

Since when did a turbo constitute a complete kit? The turbos they use are fine. The turbo kit they provide is a piece of crap. The adapter is poorly casted and needs to be port matched. They used a poorly sized internal wastegate that creeps. They used an overly large oil feed line with no restrictor causing premature turbo failure. They used a regular rubber drain line that is susceptible to cracking and causing fires when the oil starts leaking onto the exhaust. The downpipe is poorly casted and cracks pretty easily along the welds. BUT the turbo itself is fine.

I'm sure this community would love your expertise on the matter and show a DBB making more power, given ALL other variables being equal, over a journal bearing. Please, show us what a GT is supposed to spool on a 3sgte.

Everything in life (which includes turbo's and tuning philosophies) is a trade off.

I guess you can say they "do the same thing", except for the fact that the td06 now did 430 ft/lbs instead of the typical ~250 ft/lbs of the ct26. I guess you can say they are the same, except for the fact that the td06 now also has significantly more area under the curve than the ct26 will ever get.

Maybe...because they can?

I can name you a person right now that is changing from a td06 to 3071R. This same person also has owned ct20b's, hybrid ct26's, GT3082, greddy td06, and ats td06...

I guess trying to have a civil discussion with you is a lost cause.

[mr2ya]

WOW all i said was (it sucked)
crap for the money
bad idea for the money
kit or turbo alone
however you look at it
gad guy is changing to 3071
He will be happier!
never said ct26 could do the same topend as tdo6
but that topend can falloff just like with stock ct26
little frostrating when someone argues
that a turbo designed over 20 years ago
could be as good as a new style turbo
this has no logic

are you going to take push rods over OHC's
HJs over BJs
leafs over coils
where does it end

guess all the dyno sheets i've seen are all wrong
mr2 is not the only car that has used both similar turbos in ?

Rushing to order my super cool greddy sticker right now
oh yeah it comes with a turbo too

[HarrisRacing]

I just put a small 16g on my MR2 turbo...

It cost me 324.00 total in parts and a bit of elbow grease. I will have pictures and videos of the driving impressions soon.

But yes I believe some GT turbos are better than some mitsus. The EVO3 16g is one hard-to-beat turbo for 600.00 though. I pulled the small 16g off of my 1998 GSX and put an EVO 3 and WOW the difference was amazing.

There are FAR more td06 graphs better in every shape/form than gt3071 dynos. td06 is the gt3071 killer.

[mr2ya]

good deal on 16g
all this got blown out of perportion
point was if gotta spend around $2000 or so (on a whole kit)
to get a gt series of somesort in the mix
over getting a TD0 based turbo

like i said if you get a deal on something GOOD go for it
but to suggest to someone go buy this kit or turbo
new for MSRP
Iagree not many graphs at all on the 3071 im refering to
as with the .50a/r cold side is a fairly new item
so may be in someways smaller than TD06 (not sure)
still has around same or more peak power

[mr2ya]

bet that 16g is a trqy
