Greddy Turbo Upgrade Bullseyepower.com
#26
I really don't think you can fit any bigger turbo in the spot were Greddy has there's.. I was thinking about relocating mine to up front where it is easier to work on and just in case the upgraded Greddy turbo dosen't perform any better, then I could install a bigger turbo and just refab a few parts..

Colin204, Hats off to you, Really.... I don't know how you did it, but everytime I screw with mine I hate that tight of a location.. As I said before , I'am really thinking of relocating mine up front to make it alot easier to screw with... Has anyone out there done this yet with the Greddy Turbo ?....

Anyways, was trying to put on the oil drain line snorkel tonight (the silver pipe that connects the black hose to the turbo on the oil drain) and the gasket that originally came with the greddy kit broke Anyone know where to get a new gasket or am I stuck buying a oil drain kit with new hose and gasket. I really do not think that "make a gasket" stuff will work cause it would be smeared all over everywhere just trying to get it on there. Its tight around that manifold and turbo.
Let me know, if it was not for little problems, i would be reporting on how the new turbo feels by now. Thanks

Well, adrain-1 and Jeff it seems possible to install a larger turbo in the Greddy location. I guess what I'am saying even if we can , why would we. It just makes alot of sense to relocate it up front somewhere to make it easier to .
1. Remove it if we have to work on it
2. Make it easier to check and or fix oil leaks from connections.
3. Make it easier to work on or replace the Actuator
4. I just hate working in that tight of a location under the car, just getting rid of the aggrevation of that and the time involved is a plus.

I can agree with that, because working in that small space, underneath the car sucks. But at the same time, I like the fact that it is in a really stealth location.

Hey Jeff I beg to differ, You say"
1) Complicates plumbing - I still want to use the existing Greddy Cast Iron Exhaust, so just the small rerouting, you think that's alot...
2) Exposes alot more Heat - Why all the other after market kits show, what seems to be damn good wrap.. Try to keep the wrap on the Greddy's location, It was hell to wrap from the beginning...
3) Requires alot more fabing - That seems the same as (1)
4) Look too after market - I don't know about that, the RX-7's turbos are to alittle more exposed than the 8's and that don't look bad. And I would rather have the Turbo more exposed for so many more benefical reasons, than not have exposed because it looks alittle after market...
We all can have our own opinons, and nothing is wrong with the Greddy kit , I have it and love it, But know that I want more and have been through the installation myself, which sucked, I'am working on away to just reroute the Turbo and some minor parts, just in case I go to a bigger turbo and I don't want to screw around working in that location again.
Also you know Turbo's are not maintenance free sooner or later, and when that happens I rather be able to work on it with out swearing up and down because I can't get at a part...

Moofsta,
Been away for a few nights . . mine was leaking into the exhaust itself not from the turbo itself. Lots of white smoke cause of the oil in the exhaust too. I did have a drip from the cat pipe flange but that was the only place oil was coming from on mine. So where does your oil leak look like its coming from?
Update on my upgrade:
This has been a bear! I finally got it all together and cranked the car for the first time. No road test cause I have a leak at the oil drain and at the oil feed! haha! I just need to tighten those up I hope but I quit for the night. No road test yet.
This has been a challenge cause I had to modify the acutator bracket, cut one of the intake pipes to fit, waiting on a length of silicone hose to patch together to of the intercooler pipes better, had to battle with the intake coupling and the exhaust manifold (intake is 3" on the turbo and rest almost on the manifold).
Dummy problems I had:
Change the oil feed line, had to get new fittings
Could not get the oil filter off, had to remove the whole oil filter assembly from the engine
flooded the engine when i tried to start it
. . . go figure, not been my week!
I hope to have a road test tomorrow night, if so I will report.

Hey zoomzoom nice move..I am thinking all the possibilities for more hp but nothing yet..I can't afford changing all the turbo kit...2 new rotors with lower compression to raise boost would be the best..I don't know.
i have changed everything and i don't know what to do right now..I hope my new mechanic-tuner will solve my problem in his rx8 promo...
Please keep us informed and i hope everything will go as you want!!

Jeff, get back to you soon, meet with my tuners and I hope to have a drawing or two to show you, then I will continue with this discussion, Also I did look over the OEM setup from the RX7 and your right on number (4).... All the ones I've seen had after market intakes, so I had to find one non- touched...

Okay guys, been really busy for a few days and finally have a second to give you all an update on the bullseyepower upgrade road test.
The install took a while cause I am only the second one ever and maybe just maybe the first one, not sure. A few things had to be worked on which took lots of time but I am reporting all this to bullseye so they should be correcting and making the install easier.
The List of Issues/Corrections:
Oil Drain- Used the oil drain off the old greddy one, it hits the manifold and the turbo housing so it does not seat well on the flange, thus leaks like crazy. I heated it with a mapp touch and made it egg shaped in the area it was hitting so that it cleared. Problem corrected.
Turbo inlet - inlet is three inches thus when the coupling is put on it lightly touches the exhaust manifold. I cut a small area out where it was touching but not any further, place heat shield wrap there too for extra protection, seems to be fine now.
New Oil Feed: bought a new oil feed line cause its good to always change these when you take the turbo out. It is a smaller diameter which should make the pressure greater to the turbo which I think is good. Had to buy some brass couplings to make it all fit though
Air inlet pipe- the old greddy one had a flange built in, had to cut the flange off to shorten the pipe to mate up with the intake coupling.
Compressor piping- had to use a 90 degree coupling to mate with the first pipe then about 4" silicone coupling to mate the first pipe to the second pipe, no biggie.
Acuator/Bracket: had to trim some off of the acutator bracket to get it to fit in the space but once install was complete and engine begin to move on the mounts like it should, it jams into the firewall/wheel well. It is just too big. they are making me a new custom bracket to fit in the space and should be no big deal.
Now the drive: I had the typical issues, oil leaks which I had to fix and then the test drive.
First thing I noticed is that the turbo itself whines and whistles way more than the greddy which did not really make any real noise. The car sounds like a race car, very high pitch whistle that does get attention. i like it, some of you guys may not, each to own i guess.
Second thing, you have to be very very light on the throttle. just a little gas and the turbo quickly spools up to full boost (about 7 now, i have it limited by boost controller) and sticks you to the back of the seat immeditely. The turbo spools up a lot quicker than the greddy one which I used to be impressed with.
Third: the up and down idle that we had with the greddy is gone entirely now. I think the greddy turbo surged alot and messed out idles up. This turbo was designed to have less or no surge so the idle is silky smooth, i dare to say better than before I was turboed!
The car seems to have lots more potential with this cause the turbo seems to be at ease with the boost response, it does it so easy and quickly. Not sure what the top end is but I will be talking with them tomorrow and will ask.
All in all, i am very very happy with this turbo. I need to get it tuned but the butt dyno tells me the car is much stronger than with the greddy turbo.
I will update you guys once I get the new acutator bracket on and give another report.

With the amount of money that mod cost, I'd hope that it would give you MUCH more power than the unmoddified T618z. So is it able to hold boost, or does it still fall off at higher rpms? Also, did you ever get that number for the cfm? Keep us posted more on the dyno too! Sounds promising though!
