Well it was a parts car that got "re-assigned".I got it running and it ran so good I kept it as a Driving car.
my bad I guess..lol!

JWteknix 08-12-12 11:31 AM

its said you have to shorten the oil pedistal I shortend mine but from what it looks like wit the spacer idk if it was nessisary

Rob XX 7 08-12-12 11:37 AM

I didnt touch my fill

tuscanidream 08-12-12 12:09 PM

Thanks for the info guys. Waiting for my uim and tb to arrive soon in the mail. Still have to order either the greddy FD compression tube or modify my FC one to fit.

Rob XX 7 08-12-12 07:06 PM

Fc one will not fit, better to sell it and buy a fd one

I've seen in a thread here before where some one made a adapter plate. I'll see what the best option for me is when my FD parts arrive.

S5 lower intake. No spacer.

Material added to lower intake and inner studs moved. Some elongating of holes in upper intake. Grinding under upper intake to clear fuel rail.

No intake port matching. The holes in the upper intake are smaller than the holes in the lower intake.

This was Soul Assassin's intake setup and he made something like 500rwhp with no intake port matching.

ooo real twins lol

with the s5 theres less of a port match needed, u really should with the s4..

Man! You've been here for a while, I bet half these guy's don't know about Soul Assassin's car.

I received and test fitted my fd uim and tb today. So... Which lower oil fill tube will allow for proper clearance?

JWteknix 08-16-12 08:15 PM

I cut mine and rewelded it S4 tII

K-Tune 08-16-12 08:37 PM

I just used FD parts for my oil filler.

Thanks.

JWteknix 08-17-12 06:07 AM

isnt the fd filler plastic and bulky? i just shortend my t2 one by like 2 inchs looks nice

eage8 08-17-12 10:22 AM

is it the lower section or the upper section that is longer on the TII?

BLUE TII 08-17-12 12:19 PM

Its the lower section of the oil fill tube that is too long on the TII intermediate housing.

fc3s91 08-18-12 10:57 PM

I used the lower section of the fd oil fill . I didn't have to shorten the upper neck.

joeylyrech 08-19-12 07:38 AM

I changed mine 2 a cosmo filler neck with fd lower cause i had a fd setup and it broke.

... and here is my s4 - Turbo Garrett T04B - MicroTech LT10s - special CNC adapter plate (3,0cm) - ...

Roen 09-12-12 10:32 AM

Nice job.

eage8 01-25-13 09:57 AM

how is everyone modifying the greddy compression tube? (to make it not point towards the alternator)

did you cut it at the flange? any pictures?

Rob XX 7 01-25-13 10:26 AM

cut and welded

I'm just leaving mine and I'll have the outlet on y vmounted intercooler modified (again) to meet the greddy compression tube. Should allow for easier access to spark plugs.

If you want to see how people have modified it, just search for some pictures.

eage8 01-25-13 11:21 AM

yeah, that's what I just did :p:

I found this one (which I think is Rob's), which looks like he added material?:

and this one which looks like they just sectioned and rewelded:

I also cut a wedge out of the back and welded it back together.

So, I've wondered through this thread enough to want to do it to my FC... Thing is, im not seeing anything on doing this for an N/A S5... is it possible, or worth doing???

That is because your car is an S5 N/A..
Turbo the engine or get a TII engine then you can do this too!

nitrofish88 04-07-13 07:41 PM

well, thanks for solving that riddle bud.

This would make an N/A much slower... there is a lot of intake tuning in the stock N/A manifold, especially the S5 one.

No sweat..I'm Good at crosswords too..and am currently going out with girl that can tie a cherry stem with her tongue!.

Has Anyone tried using the OEM S6 BAC valve and TPS wired to the Factory S5 ECU, I am contemplating trying it out from what I can tell from the Service Manuals they should read the same and function the same but not entirely convinced.
Not sure if Rtek or Standalone (again) is the way to go on this project.

whats the purpose of doing any of this if you have no way to tune for increased air flow?
I would leave well enough alone until you are ready to go forward with a way to tune the car.

This will be the second time I do this mod but the first time I am considering not using Haltech.
Rtek uses the OEM ECU but allows for timing and fuel adjustments, not as powerful as haltech but much less headache.

So In short I am not considering doing this with a stock ECU, either an Rtek 2.0 or another stand alone.

genito75 06-26-14 05:37 PM

Do you still make this adapter?

Well, thats the one good thing about the old Bosch L-Jetronic based air flow meter engine management.

Since it actually directly measures airflow it is more tolerant to changes that will affect system volumetric efficiency changes.

IMO its only really when you get into shorty custom intake manifolds where the metered fuel getting injected wets the walls instead of entering the engine due to poor intake design and lower velocity/more reversion that you get into trouble with AFM systems.

Or when you exceed the measuring limits of the stock system (airflow or boost pressure) - which is going to be about what the stock injectors can handle.
