Since I was taking some phone-cam pics anyways, I thought I'd take a few extra that would fit perfectly here!

This is my second try at having a reliable turbo'd rx8. Without MAJOR help and generosity from a fellow member here, I would have thrown my car in the trash. I got help stripping off my kit (well, he probably pulled ten bolts for every one bolt I pulled) and I'm about to put everything back on my car, hopefully with some supervision.

Here are some parts I just got back from KOOL COAT ceramic coating:

 

I will make sure I post a review of the turbo when I am done. I would have had it all done tonight, except I punctured my motor mount trying to get it back in.
Oh and thanks for the kind words.

Yeah it's been sitting in my garage...haven't started it up in a month, so I'm sure it's from the winter. It's a brand new battery, so if I can't get it to work, I will get a new one for free anyways.

I have the Greddy turbo kit, with an upgraded Greddy turbo from fluid.

 

105k miles, 30k of which have been boosted. I am doing my own tuning as well.

^Wow Yambo, I think you have the highest mileage of us Overlords here

 

If I want to run 14+lbs of boost, what size injectors should I get and how many?

 

Yeah. I recently purchased a motor to have rebuilt for when the current one inevitably goes to rotary hell

The 570 cc ones that Cam sells should be good enough for 14 psi. Ask me how I know

 

Well I'll be picking up a spare Garrett T04E 60-1 P-Trim as I have reason to believe the seals on my MP T70 may be shot.

It only seems to smoke after a hard pull though. There is no shaft play @ all neither

What are some reasons for premature seal failure?

 

Smoke at idle or smoke during hard boost?

 

Smoke @ hard boost

 

Might not be the turbo then. Could be running overrich, ignition etc....

 

Well I should also add while doing some maint on car a while back I did notice some oil in IC piping. Also I'm consuming more oil than usual had to fill up w/2 quarts the other day just after I did a oil change 3 weeks prior.

Don't the seals on a turbo require + air pressure via the compressor to keep oil from seeping past them?

When I swap out turbos I'm going to run checks on my feed & drain lines. Need to install a inline oil pressure gauge on my feed line.

 

Well yeah that does sound like a blown turbo....

I was helping a guy tune his 7 with a T70 that was actually missing a rear oil seal - and that thing smoked so bad that it looked like a smoke screen.

 

^Rofl, that sounds like fun!!

 

It was a pinned and bridgeported 13B... once that monster turbo got going it hauled....but yeah the old turbo was a nightmare I thought the neighbors would call the cops when he pulled onto my street.... HAHA

 

Esmeril kit gives 2 1000cc injectors to replace the secondaries. I think Chris is running 14 psi or more currently. But I don't know if that's overkill by a lot, or just enough. ::shrug::

Not sure if psi alone is the deciding factor for injectors since different turbos flow differently, so I leave it to the wiser men to answer concretely.

 

Derek, is the shaft thrusting any? It's only supposed to have slight side-to-side play.

Smoke from boosting can come from all sorts of stuff, btw.

^if oil is in the I/C pipes tho, wouldn't that indicate a bad turbo?

 

My inclination would be to go with larger Secondaries AND P2's. You don't want all of the fuel being added to the secondary ports. I think 1000cc's into the secondaries with stock small P2's wouldn't be as good as medium Sec and P2's.....

Will depend on what EMS you are using as well...They will all add additional fuel differently.

That's been one of my beefs with the first iteration of flash tuners....the ability to add fuel where you want it is governed by the stock ECU's fueling scheme. I'm hoping that will be one of the things that can be altered at some point with these systems.......till them I'm back to wiring my standalone

 

It can indicate that. It can also indicate an issue with the oil control rings in the motor. Even a crankcase ventilation problem as well.

Yeah, typically you use horsepower as the (easiest and simplest) measurement to figure out fueling needs.

I know 730cc P2 injectors will get you close to 400-rwhp. 1000cc's are a bit overkill for anything under 350-365rwhp.

 

Simpler than that... use Airflow and AFR.

If your target AFR (safe) is 10 and you wanna be able to flow 44 lb/min of air then.... you need 4.4 lb/min of fuel.... :D

 

^Then just convert 4.4lb/min to cc and you're golden. Yeah, that is easier....damn.

I think Kane is the King Of Lazy



In a good way

 

Yeah...... well the nice thing about an AFR.... is it is a ratio!

So use cc/min -lb/hr -lb/min doesn't matter.... as long as they are both the same measurement.
