just curious about the greddy t67 turbo kit i was wondering if it was a ball bearing turbo, anyone have a dyno chart ? thanks for any help

 

we have like the same mods, but you have more TQ? Maybe its from the psi?

 

None of the Mitsubishi turbos and all Greddy turbos are Mitsubishi. Normal thrust bearing design.
They control spool and power by the size of the exhaust housing size.

MAx 520 on the wheels on 29 psi C16 race gas.

 

cool, i dont know every car is different. im runnin 23 psi because i blew my head gasket and when i replaced it with a thicker one it lowered my compression ratio so its about the same.

 

The Greddy T67 is a 25G. The two I personally know of both cracked their manis. There was talk a year or so ago of a true 20G coming out with the kit that would make good power and have great spool, but nothing ever came of it.

what?????

 

might as well go AMS 35r

 

Just go with a ETS 57-trim. Great turbo, great spool up, and 420+whp on **** 91 octane gas .

 

when talking these kits u have 2 specify which hotside u refer 2. the early kits that came out had an 8cm hotside. the later kits came with either an 8cm or a 10cm hotside. or u can buy the turbo separately & get a 14, 17, or 19cm hotside. the greddy 25G feels just like stock except with 50% more power pushing torque. it is used extensively overseas with great success. there's a shop in japan with a 3rotor rx-7 pushing 2 25G's.

remember, journal bearing turbos have longer spool, hit hard & last forever.
bb turbos spool fast, hit early, have more linear boost curves, but last 1/2 as long...

if i do a big turbo, it will be a 25G or 1 of greddy's other 10+ year performers like the T78, which BTW, has many 9-10 sec timeslips on it's belt on motors as small as 2.2L
the bb turbos are most practical as kits already exist for them & pricing is very attractive which is obvious by the # of guys on here running 35's thru 42's...

 

no offence but why would you want to go with 10+year old turbo tech?? come on mate the turbo game has moved on very fast in the last few years. garrett started it with the GT but now most are coming out with new stuff and the playing feild is much more level these days.

if you want tried and tested turbos then why not look at garrett or turbonetics?? they all have intresting turbos that could perform better than the Greedy stuff.

thanks Chris.

 

i just choose to be different. the only other option i would consider is a HKS T04Z on a 2.2L stroker. sure it's expensive as hell & there is no bolt on option for the EVO, but who cares. Greddy turbos have been working well & continue to work like the guy who used a rare T78 Greddy kit for his Lexus SC300 that is not even stocked in Japan!!!

what i'm waiting on is to c an EVO with a Garrett turbo with over 100K on the odometer running strongthat has regularly seen higher than stock boost over 70% of the time.

it appears that the majority of people no matter what they do in life follow the masses. sure it may work and that's the easy way 2 live, but where's the originality/individuality???

like out in AZ, everybody lives in a beige house w/an HOA, drives an SUV, shops at ikea, plays golf & votes republican & we all know AZ's hatred for asians, blacks & hispanics-unless they need their lawns landscaped, or some other cheap labor job done...

 

House DJ, I've run 5 different turbos and managed to blow both that were journal bearing and one was made by Mitsubishi. Say what you want about these liking 27 psi, but my experience is different.

Secondly, there is nothing intrinsically good about being different. Being better is a positive, but being different for the sake of being different isn't. You can blow all your money being different and end the end, you're no better than the rest at twice the price. Do it better or your just pissing away money to be a poser.

 

Someone else who decided to be different:

Just To Be Different

 

My eyes were open wide watching that I've been driving an RS (no a/c) in the Caribbean for over 4 years.

I have a friend down here with a Greddy T-67 on an Evo 9. I wouldn't rate the kit personally.

 

bottom line is GReddy has used Mitsu turbos for years & many people overseas seem to enjoy using them. ppl in the US don't like them bcuz it seems every1 over here prefers drag racing where a journal bearing doesn't work that well in that application unless it's a t78 or larger. in road racing, however, it appears that all the top evos in japan run other turbos that ppl in the US will not spend the cash to get. Cyberevo uses the Apexi RX-6 kit. it works well for RR, but not for drag.

i don't see what the problem is in choosing a turbo that no one else (in the US) is using especially since we have Japanese cars. besides if anyone really wanted the best Garrett turbo for their car, they would spend the cash & go with HKS. they take all the strong attributes of the Garrett design & make it BETTER!

use whatever turbo u want to use, but if there is no originality or individuality in your design/application then we might as well all be called cattle... mooooooo


if the guy wants a GReddy kit, let him make that decision
