Pt6776r

Has anyone had any experience with this turbo on a 2.0?

If so please post some feedback on it and your experience.

I have heard of people using it on a 2.3 motor but nothing really on the 2.0.
This turbo is also refered to as a GT37.

Thanks

The turbo will pull to pretty much any RPM you want. It's still making power above 9k rpm's. Hey just on a side note, you dont want to run JUN 272's on a stock ECU and a GT37R is going to need more than 780cc injectors, you will need at least 1000cc to get anywhere near the potential of that turbo... Just throwing that out there

Thanks.

I have heard that the stock ECU cant really handle 1000's.
I would like to really test what it can do before going AEM as well as 1000's.

However i really want to test the stock ecu. I have seen a couple post defending the stock ecu, they seem to be making good reliable power.

However i have not seen to many post about the PT6776r but i have seen post on the GT37. However Precision states that there is no GT37 and its a PT3776R so i just wanted to see if any other EVO owners were using this particular turbo, ive only heard good things about it.

Thanks for the feedback.

Stock ecu can handle 1000cc you will need a injector driver box and you should be ok but your car will not pass over 610 whp safely with the stock mas and the limts that the stock ecu has.


Good luck with your build

I did not know about the injector driver box. I'll look into it.

What about the ballast resistor, since the evo comes with low impedence injectors.

I have heard that also about post 600 with the stock ecu is not possible.
I will eventually go with AEM but i just want to push it to see what it can do.

Fynetune and toyomoto are interested in this as well.

Thanks again for the help let me know if there are anyother items that be of help aswell. Im pretty sure it can help out alot of people.

I talk to ams about this a long time ago and eric told me its possible to run up to a 35R on a flash and make great power and at the time they had a 35r mr with a flash and it was laying down some good power.

Isn't the pt67 a full t4 turbo? I think someone on here was running, one, but I know plenty of turbo hondas have had success with them. This is a big turbo and will make power late, but will be strong up top on the 2.0. I am running jun 272 on aem with 1000cc injectors. I just don't believe the stock ecu will work very well with this.

Precision offers them with T3 back housings also. They offer a choice between a .63 and .82. I have the .63 to help with spool.

I hope to find out if not AEM it is.

Jean, have you looked at the full-race t3/t67? That's another option for you. I think the juns will work on stock ecu, just not as easy to tune as the aem would handle them. Keep us posted.

There is only one way to find out.

I have read a couple post and heard alot of things about the stock ecu and its capabilities.
I am really interested to find out what it can really do. If so this can bring another option (well its already an option) but may help other evo owners out in there decision making with more options to choose from.

In other cars such as BMW's(off-topic) they have supercharger/turbo kits tuned completely by the stock ecu. Some making well over 500 rwhp +.

I have also done some research on the Juns i think it should work out. (the HKS 280's were my second choice)

I should also change my sig im going to try 1000's on the stock ecu.

If you are refering to the turbonetics t67, i looked at it and the innovative turbos as well. However after some reading and homework i decided to go with the precision.

I think this Tilton clutch is very impressive but may take my tranny to an early grave.

I am very aware that this would be alot easier with the AEM.

Thanks for all the feedback.

I don't see why the stock ecu couldn't handle large injectors, unless the drivers are much weaker than the older DSM ecu's. The DSM ecu's can handle 1600's pretty well.

Stock ECU is certainly good for 880s which would be the equivalent of 1000cc's with an AEM (due to different/crappy injector drivers). The stock ECU is adequate to at least 500 whp, if not higher.
