GTRS ---> 3076R, what hardware do I need to change?

[jayt991]

I've decided to ditch the GTRS and go with the 3076R. What hardware do I need to change out to make the swap? I've already got a nicely built motor from QED.

* Manifold
* Downpipe
* Turbocharger
* Compressor inlet silicone hose
* Turbo coolant/oil feed and return lines.

If you are interested send me a PM as we are just getting ready to release the complete GT30XX hardware kit.

[B6Lovin]

^don't forget new rods...

or if not that: a new block, pistons, rods, crank.... etc

[A4natomical]

it says he already has a builld motor from QED tho^^^

Ah yes...forgot about the rods

[B6Lovin]

yeah, i didn't word that very well.

i was talking more to issam about a "complete" hardware kit for a 1.8T to jump right to a 30 series

[A4natomical]

oh gotcha.

[Killerteve]

And probably new injectors unless you have 630's.

[absolutegtr]

Obviously new hot side piping for the intercooler

[mike-2ptzero]

Better clutch and bigger FMIC.

[B6Lovin]

Obviously new hot side piping for the intercooler

and possibly cold side too if he gets one of the intake manifolds and a bigger TB that are out/coming out. nobody makes a kit that will fit those yet... so custom piping it is.

[absolutegtr]

quick off topic question:

On intercooler piping if you are using worm-style clamps and have rolled edged on teh pipe....how tight do the clamps really have to be? I ALWAYS seem to pop the T-bolt and worm style clamps all the time....I guess I am tightening them way too much...

how flush do your pipes sit? you want them to sit as close to end-to-end as you can get them so that the couplers just have to be snugged up on them. if the pipes have to be pushed into place or have a gap between themselves and the next pipe it's a lot more likely to blow off - no matter what you do. (ask me how i know)

and i get my clamps pretty tight just to make sure

[jayt991]

I've already done the clutch, FMIC.

Head's been port and polished, 20mm wrist pins. Blocks ready for sure.

Whats the difference with going with a TIP or without one?

[Siggiepop]

i'll take your injectors if you're selling em

TIP = MAF setup or intake placement away from turbo

No TIP = Mafless and filter bolted to turbo, less restriction

[jayt991]

What clutch and FMIC?

OCT FMIC, and OFE SS.

Which setup is more recommended for a DD, MAF-less, or with the MAF?

[HIERLEVELZ]

^^^
I would like to know more about that as well. I'm assuming its all in the programming?

Well the nice thing about mafless is that there is 1 less wear item that can throw off the tuning. But with mafless the tuning has to be much more refined since it is no longer using the MAF to figure out load.

[actlsub9]

MAF is better for DD.

[jayt991]

I'll be running the old REVO 430 file, what's the general consensus on injectors...550's, or 630's?

[actlsub9]

Depends on what MAF size.

[Condo]

You'll need 630's for the 3076R. 550's won't be able to keep up.

[A4 TSCHUSS]

630s cant keep up either on my 2.0

Dont know if it is because I have 2.0 and cams and the 3076 or what but I am in the 90s for duty cycle at 24psi in the upper rpm range. That is only going to 7200, I dont know what will happen revving to 8000+

[mike-2ptzero]

Well that really doesn't matter unless the ecu has to pull back so much fuel that it causes the fuel trim readings to max out. This is the advantage the 2001+ A4's have because of the wide band 02. Now if we were talking narrow band it would have a huge effect during WOT.

Well you really won't know that till the car actual starts to lean out up top even though you keep throwing more fuel at it.

630's with a 3" housing?

[HIERLEVELZ]

Does Unitronics and the like provide a Mafless tune? I need to remove that cluster fuck intake I have and put a filter straight onto the turbo.

I was under the impression that the ECU could pull back up to 25%.

630s are 43% larger then 440s.

That is, if you are still using the stock MAF size.

Since when? Your logs of the new fuel pump show things are alright. And the REVO files run a tad on the lean side anyway (relatively speaking). Our engines like to run slighty rich.

Eurodyne offer MAFLESS tunes but your set up must be constant to the package.No deviation or else you are looking @ mail order tuning for 3 weeks.

Yes for idle/part throttle and I dont think that counts for decreasing fueling thru lemmiwinks.

[B6Lovin]

MAF is better for DD.

how do you figure that? other than my current problem which is due to a totally unrelated issue, my car has always driven, idled, started hot or cold, and boosted just like normal. GTRS and 3071R

Does Unitronics and the like provide a Mafless tune? I need to remove that cluster fuck intake I have and put a filter straight onto the turbo.

yes they do, and it makes things a lot easier to work on/look at when it's time to get under the hood if all that crap is gone.

[HIERLEVELZ]

Anyone running a MAFless Elim setup? Just curious how they setup up their filter.

I am at like 94% duty cycle at 24psi and I have a 7200rpm limiter so I dont even know what it will do if I spun 8200 which my head is ready for. So I dont see how that is alright. If I turn my boost to 27psi like Shawn was running I would be over 100% duty cycle. Last time I checked tuners want the injectors running in the 80s and 100% duty cycle is not a good thing. So call me crazy but that is definitely not alright.

I did not realize that.

Guess you need some 880s then.

Why would you want to run MAFless with a filter with an eliminator?

The stock MAF is larger then the compressor inlet, so the MAF is not going to be a restriction.

When I say filter I mean a screen so no FOD gets into the turbo and messes up the compressor/turbine blades.

What Greg said still applies, the stock MAF diameter is larger than the GTRS inlet so it is not a restriction. And FYI, a screen provides more restriction than a filter

just so it looks 'cool' when you pop the hood


the whole point (as i see it) with the eliminators is to make the engine bay look 'stock-like' yet the car makes more than double the power than it did stock.
