sasha have you considered taking a look at the Bullseye s300 series turbos? the s374 billet "batmowheel" is rated about the same as the 7675 cea and is available with a divided housing. not sure how it compares dimensionally though, but should get similar spool, the compressor is slightly smaller but the turbine is slightly larger 83mm vs 81mm on the precision. but i imagine being able to use a divided housing should pick up some decent rpm with a qsv

 

Looks good sasha!.. Always keeping an eye out on these threads lol

 

No I have not, and as far as fitment goes, if I can fit this monster 76mm with an H compressor cover anything will fit. As long as the turbo compressor inlet is no more than 4".

I am willig to custom build with any turbo anybody wishes to experiment with. I just have to have the turbo here to ensure proper fitment. If modifications are needed I can just build a custom up-pipe/down pipe and you are set. I would still like to test fit the QSV, hard to invest in to R&D with no sales though.


Looking at this 366, I can tell you that it will fit without any issues:







EDIT:

The S366 compressor should be good for about 600whp, and with a QSV would spool very well.

 

pte6765 turbo is great, i had one on my evo8 made 800hp with 41psi.

 

yah looking at the borg units they are pretty comparable to precision but the wheels that bullseye power is making (the batmowheels) have me intrigued, interestingly they are using the same blade design that GE uses in there jet engines. just browsing around there was a s2000 running a 3.4L 2JZ with head work and cams making 902 rwhp on the s368 batmowheel from BEP, and they claim if you get the batmo cover you can eek a little more out due to increased entrance velocity. i know its not the same as our engine but a 3.4 with cams and head work should be pretty close, theres also a 3.4L supra running the s374 with batmowheel at 950 hp at 30 psi with claims of alot more left in the turbo, went like 227 at the texas mile followed by a 243 pass at 33.5 psi.

can even order them with garret dbb chra's(borg warner dosnt offer ball bearing turbos outside the efr line)

of course before i seriously look into other turbos i need to get my car built first instead of just a pile of parts sitting at home waiting for me to get back

 

I must admit that after looking at these turbos the S366 looks great. The 66mm compressor wheel would put down some good power, comparable to the 6765. The turbine wheels are a bit larger, and that is nice for flow. It also available with a 60mm and 63mm wheel.

The S374 has too big of a compressor cover and would not work:

EDIT:

Looks like the S372 would be an option as it is available with a 4" inlet compressor cover.

 

could be a nice option for someone who wants a bit more power then the 6765 but still have some decent spool with a qsv. hmmmmm mayby one day down the road, gotta see what the current setup will make lol

 

Just a small update. The IC piping is now in place for this horizontal flow intercooler:





The customer will be sending his exhaust piping over soon, so that I can add a Precision 46mm w/g. Other than that things are ready to go as far as fabrication goes. This is a very simple upgrade from the current kit I offer.

 

Very nice work!

 

+1! How are you guys liking the Borg Warner turbo?

 

Not a fan at all myself. They also had some issues with them and there was a recall. They are bulky, and hard to get as well.
