I have seen this.. inside my last motor that popped a few yrs ago.

The oil analysis at the time indicated 58% reduced oil viscosity due to fuel in the oil, the washed bores and cylinder head ports were a testament to this also. We had the Sard injectors tested.. and it indicated a very poor spray pattern with little atomisation.

ASG indicated to me at the time that they had a lot of trouble with Sard injectors, especially the 650s.. some are easy to tune, others aren't. The ones that aren't are the ones that have the poor spray patterns.

It's not that they're bad as a whole, they're just inconsistent between sets.

Thats it im changing them! Cheers

agreed, I had huge trouble in trying to get a consistant idle with Sards. Decaps run much better

The large injector vs De-caps debate was done and won over 5 years ago.

Alot of 300+ hp atw subaru's run de-caps with no issues. Use the money saved to spend on other aspects of the fuel system like in-tank surge assemblies and quality fuel pumps.

Where does a 3076 sit in relation to a 2835 and a 3037? Same as a 3037 pretty much so a 450hp turbo? Should work pretty good, or consider a TD06-25G.

Im running SARD 800cc side feeds. My idle is perfect. Like OEM.

But my overall fuel economy is shite. really really shite.

The injectors tested in that picture should have been tested at rail pressure of 43psi. Testing below that is a bit meaningless, however you can see that they still have a nice V pattern and not a water hose.



Injector on the left is a scoob yellow top. Injector on the right is a stock RX7. That is a shit injector.

Decapping only removed the diffusion plate at the end of the injector. So it shouldn't effect the flow pattern too much when you mod them. If it does, something is wrong. I have read (but never seen) that some Subaru models come decaped from the factory...

99% of the 'decaps are shit' come from people who have never tested, looked at or are interested in the mod.

When I flow tested my decaps (wrx spec injectors), I also flow tested a set of sti pinks (550cc). I could not visually see any difference in spray patterns. However, I have no photographic proof so as far as the internet is concerned I could be full of shit

If you do mod your injectors, flow test them and have them sonicly cleaned and new o-rings installed. I've used Jordan Rover Tech for this before. Otherwise use le-Yellow Pages (United Fuel Injectors are another place).

Wow the one on the right would be good for a super soaker on a hot day!

Scooter,

Had I of seen this sooner, I would of replied. Yes, most 'baby TD06's', (Blouch/GT Pumps/ etc etc - not Trust/Greddy versions) are good for 350h at the hubs. (My 06 is a 440h rated one). True again, they are not BB, but as they are the smaller end of the TD06 'umbrella' - they do not take forever and a day to come on.

On the new donk, with some cams and head work, I would anticipate getting a Joe Sac like 350h. Albeit with more torque. (As I have some secret squirrels in the new motor... ).

Oh, and although I didnt actually get my SARD 800's tuned, as someone said earlier, decaps (816cc's) will be more than enough. Lots of people have tried aftermarket bigger injectors, and just as many have come back to the chop tops.

(Insert 'i told u so' comment here..... Jester/Stace/Rob... etc).

This here... is the crux of it all:

If you do mod your injectors, flow test them and have them sonicly cleaned and new o-rings installed.

United Fuel Injection do this. Ill dig up my receipt for exact costs. Seal kits can be bought from Covs, which come with the strainer baskets, 'h' rubber seals and o-rings.

Good luck in your quest. If you want to see the graphs of the Blouch TD06-20G on a stock 207, suss out my build thread. The tapering has been put down too wastegate actuator being too weak (9 psi) and me needing a grub screw in the BOV.

As others have said, its good for a bit more, so with the new cams and whatnot in the new motor, Id say 350h/and 430/440nm.

Brent.


[EDIT] On the Garrett opinion, if you havent already, touch base with Josh, (dak dak, or the guy with the M3 thread), and get his opinion. Initially, I know the car had an issue with a cat guts not in the cat , found after some digging around, but Im unsure of the tune post this, and its final power output.
