Thanks for sharing. Nice build. It's too bad you don't have easy access to E85.

 

Thanks! I'm actually running the Killer B Holy headers at the moment, and while they do help with the spool, they are a tad restrictive due to the 39 mm primaries, compared to the 42 mm primaries on Tomei headers. As a result they do cause a slightly higher backpressure. Using the Tomei headers would have given me an additional 25-30 Whp up top, albeit sacrificing the quick spool a bit (i have run them in the past). However, Tomei headers do tend to crack / leak at the expansion joints unless you permanently weld them.

Agree with you on the external dump freeing up extra power though; i would have gained maybe 15-20 extra horses there. The reason i avoided this is cause i didn't want to get in trouble with cops. I have a resonated Invidia q300 catback with an additional vibrant ultra quiet resonator, right before the Y-pipe.

According to my tuner, I would have made 650 Whp best case had i gone for the Tomei headers with the external dump tube.

Edit: Apparently the Killer B headers are better. (Thanks @spdracerut ) https://www.iwsti.com/threads/killer...esults.322182/

 

You're welcome. Yeah i agree
As it is, I do purchase and blend Methanol with Distilled water that I get from a chemicals supply warehouse, but I have to say its not a lot of fun working with, or storing the stuff safely.
I would have to make my own E85, mixing pure ethanol with pump gas. I get around 180 miles on a full tank of pump gas. With E85, it would probably be around 130 miles or so. Overall not too keen on E85, as its not really easily sustainable for me.

 

Old thread I know, but its very hard to find data on any of these promising new turbos. I was able to secure a g35-900 with the divided T4 housing. Will be installing it this summer on a mildly upgraded evo 9. Will update with results when it is all sorted.

 

Thanks for posting. Looking forward to your results. It will be great to finally see a divided housing G-series in the wild.

 

@PeteyTurbo is this a Garrett divided (twin scroll) housing? Or is it made by someone else?

 

Screw the mild build. All i wana know is 93 octane or do u plan to go higher?

 

garrett twin scroll housing

 

its my personal car and the lack of time may prevent me from upgrading to more then pumpgas this year. I will try!
the rest of the turbo kit should be finished next week. You can see it is not finished as far as welding goes. Also had to get creative routing the dumps.

 

Any other reports on the G35-1050?

 

It took me two years (which is embarrassing) but I finally have the car together and road worthy (I do not have much time to commit to cars anymore). There were some extra wrinkles getting everything to fit with this kit while still keeping AC. For reference this is a T4 Garrett twin scroll bottom mount G35-900 standard rotation with wastegates dumping underneath. This setup is essentially 20lbs of crap in a 5lb bag as there is not much space to work with and every component seems to have minimal clearance (the wide turbine housing has alot to do with this as well). Initial impressions I have as far as spool response are very similar to FP Red powered cars. Should have some pump gas numbers soon.
