Holy crap thats huge!!! How big is the exhaust housing on that? It will take forever to spool...

AR 1.30 or something sick hahahha.. its pretty much like a Toilet ?

[Jcarrick]

Haha, that sounds about right. I think ill have a great spool time with the 12cm exhaust housing on the hx35. What do you think about modding the stock manifold? Wont it burn valves to run to high of boost/power through it?

[chipsenter]

Hahah.. Cool. Right

No no no , after modding ur Stock manifold and bolt on the Holset buddy you will not have problems with melting valves u need ur local tuner to take care of the sw for this setup. The whole package is needed if u wanna go all out though. Not only the turbo will help u having fun here. most importent thing fueling and ignition is needed correctly .

Boost i NOT always the main factor to have a well working machine.. rather a good mix of everything like a good blend in the bar ..

Cheers.

What do you mean by SW?

Oh ya, im fully aware of that. Im putting in larger injectors, a new fuel pump (not decided which one yet), and VEMS. Im not exactly sure what i am going to do coil wise right now. My stock coils are working great, but i may end up switching to some LS2 coils.

What do you think?

[Jamo]

EFIexpress coils are the daddy

[chipsenter]

Oh. sorry , SW = Software ( Chip ) stock Motronic Ecu . But never mind , If u use the VEMS management u got everything in one box and ur Laptop. But I Sugest you have a experienced tuner to adjust this. can be some nasty consequences if not.

If u aiming at 400+ hp there will be more then enough with Bosch 550cc injectors , 044 pump ,H-Beam rods, stock coils aswell , push this kit to 1,6 kgs of boost and u might be close to ur target.

I used those , worked like a charm even on 2,5 kgs of boost ....

But as long as Stock is working , not neccesary do buy expensive coil packs.

[Jamo]

034 ones are not VEMS friendly hit and miss with them plus the EFI kit has more spark output and cheaper

[Jcarrick]

Chipsenter,
Thats exactly what I'm planning on doing except for the H-Beam rods right now. I'm gonna do around 350whp and i've been told the limit on stock rods is about 400whp (granted I know the limit is different on every engine). I'm not gonna run it terribly hard until I do rods, but for now I'll be fine with my stock rods.

Once I go over 350whp I'll put rods, rings, and bearings in it and hone the cylinders.

[chipsenter]

Great

U will get ur target pretty easy I can tell .

If u look into my dynosheet on my thread I have around 350 Whp right above 4000 rpms , guessing boost around 1.3-4 kgs .

The Audi engine produces HP like grass growing

[Jcarrick]

You think the stock rods will do alright at these levels??

[Josh-stateside]

My whole thoughts on the Holset (got a H1C for the vr6T quattro swap). Is that even if i end up not happy with the turbo setup I paid less than $200.00 for it. Even if I get a decent setup from it, stock bottom end, stock everything except head gasket which will be a compression dropping headgasket. If i blow it up with a bad map, maybe just an unfortunate event then I just won't care. I'd rather build something knowing it's running standalone, knowing it's probably going to fail and have the smile on my face to know it's not a big deal. I'd rather have something break ( I know it's going to break at some point) and not be bothered by it then have something expensive and have it break.

[Josh-stateside]

Just to add to this?

If the car was a daily driver I'd do a built bottom end and use a nice precision or garrett turbo. It's not going to be a daily driver. It will never be a dailly driver and the triple A card will help when the car craps it's insides out and I need a tow home.

That's the way my mind works these days. I know it's going to break. I'm not bothered by the idea of it breaking.

same here some respect for bimmers owned a e30 s50b30 turbo, reason for going to audi, its to easy to spin the rear wheels, its hp when you can spin all four
