Hi, any guys with experience on GTK850 or GTK1000 TURBONETICS?
|
i have seen good numbers from this turbo and am in the process of finishing an FD here in the shop with a GTK1000.
it should do exceptionally well on a 20B :D |
stevenoz built a bridgeport with an 850. he said it was insane.
|
what are the specs on the 1000?
must be similar to the old 76? |
yep it's a 76mm inducer.. i can measure the rest if you like
|
yes please ^^^
and thanks |
anything else about this turbo??
|
I just recived my GTK 850, i will post pic soon.
It's for replace my T70 Turbonetics. This GTK is same size like T72 with Q trim. The name of trim is "S" just because GTK use impeller F1. |

any updates??
|
Hi! Any updates? I'm really interested in this turbo especially the GTK850. What numbers (bhp) can i expect from a stock ports FD engine? Many thanks for any help!
|
Although I don't know the specifics on the 850, my gut feeling tells me it's way too damn big for a stock port motor.......
|
Thanks GoodfellaFD3S for your suggestion. I was going to purchase one in the following weeks....you saved me! What type of single turbo do you suggest on a stock port motor?
|
GT3574, GT35R, TO4S Ball Bearing, etc... depends on what you're trying to do.
|
Thanks TripspeedFD3S. I had in mind to get rid of the twins and get a single. I was aiming for 400Bhp (with all supporting mods) but don't actually know what turbo suits me most.
|
Do you guys realize the OP is going to put this thing on a 20B???

Well, my post was directed at ITR, who I'm pretty sure is asking about a stock port 2 rotor, no?
|
I am also wondering what a GTK can do on a well ported 13b. Im halfbridge currently, now going to fullbridge. Wonder how it will respond to that?
|
Yes GoodfellaFD3S you are right i was talking about a totally stock motor.
|
ITR maybe a GT28R will be more up your alley for what you want to do.
GT35R's can be 400+ horsepower to the wheels! |
Thanks Dradon03! I'll do a search on the GT28R then. Does this turbo come with an internal wastegate? I would prefer one with an external one....
Would the GT35R be good for me too (stock motor)? Thanks again! |
A GT35R is a great all around turbo but may need some more boost/porting to come alive. Realize that with Efini twins and full bolt ons tuned you are in the 400hp to the crank range.
|
Bump for more feedback. Someone has to have some dyno time on these.
|
Wondering how the gtk 850 would work on a streetported 13b fd motor?
I'm considering getting one. The thing is i'm not going to really be on the track with it. is it a good street/highway turbo? |
On my 20B street port GTK850 with .96 work realy fine.
Probably you need big street port because it's not small turbo (72mm compressor). |
So how do you think it will perform with 850cc prim. 1680cc secondaries with a large streetport.
|
How did you get a .96 turbine, they come designed with a .81?

A .96 is a standard size for turbonetics.:)
When i will have time i will send drag video. |
Have not been able to find one dyno of a 13b with either of these?
Someone? |
How much bigger is the 850 than a TO4R?
|
for a street setup how would the gtk 550 work out? if your not looking for crazy numbers.. just maybe 400 max at the wheels? but keep pressures below 16psi?

yes 400 is just a number i want tpo eventually get too i guess you can say.. 360-370 is more my taste and if i can get a turbo to produce 400 safely it will be able to do a lil less safely also. least thats my thinking.

Really...no one dyno one yet..???

Seen a few on the dyno...they seem to spool up VERY fast and make the same basic #'s as the PTE units. You can also purchase the TC series units from Turbonetics which are the same basic unit except not BB and are alot less expensive <$1000 |
Guys, I need help to find the perfect GTK for my setup. my setup is:
13B 2-rotor engine - 2mm Atkins apex seals - 1600cc/850cc KGparts system - Streetported (moderate) - Big Greddy IC - Tial 44mm WG - AEM Water/Met injection kit - Twin power - Racing Radiator - HKS Boostcontroller (Currently running -very safe and durable- with a Turbonetics T61 with 365rwh on 14psi) Question is: Which one of the GTK650 or GTK 850 do you recommend for my setup? is the GTK850 a safe option if i run it with 20psi - 26psi?? durability and safety is important to me. The car is used for street use, but i dont mind lots of power as long as it does not affect the spoolup time too much. Thank you for all advice! :) |

Just came of the Dyno today with a GT-K 850. And was dissapointed.
Result was 386rwhp at 1,25bar. Making about 340 at 0,8, that is on the wastegate. This car used to have a smaller Turbonetic turbo before, and the owner desided to go for a bigger one. From wasgate spring to 1,2 the increase was inly 25rwhp. But last increase from 1,2 to 1,25/1,30 was 20rwhp. I assume the ports on engine is a bit small, and turbo wants high pressure before it comes alive. Maks boost is at 5500rpm. After the day on the dyno and driving the car, I must say, I just love my 500r kit on my car. |

Weird, I have a friend with a gtk1000 on an aggressive streetport rew engine w a cosmo intake and he says he has 14psi at 3800-4000...he also makes well into the 450-500whp while in the psi "teens"...I wonder what could have caused such crappy performance...
Chris. Last time on dyno we did not get more than 330rwhp, before we found out the front rotor was gone. I did a compression test day before dyno, and all rotors are around 110-115psi. Setup is: 13B 2-rotor engine - 2mm apex seals - 1600cc/850cc KGparts system - Streetported (moderate) - Big IC - Tial 44mm WG - AEM Water injection kit - Twin power - Racing Radiator - HKS Boostcontroller We do not find out what is wrong. I been on dyno with at least 10 cars with this turbo size, mostly all of them with Garret turbo's, and all off them have made over 425rwhp. This turbo and setup is new to me, and i just want to know why the boost is this slow and power this low. All cars are done on the dynapac dyno, with DIN correction. |
