Which cams?

[slopoke]

I did a search because im damn sure it has been discussed on here before but i couldnt find anything... I found some reading on catcams #3658 and dahback but where the hell can i buy them in the states? And does anybody have any personal experience with any aftermarket cames for the 1.8t here? Ot biggest i plan on goin is gt2871.. But i would like some lope and run 12's easy...

[Pete@IE]

None of the cams for hyraulic lifter are going to give you any lope. I've got a set of billet 3652's in mine and it doesn't even lope unless you get the idle down under 900 or so, and those cams would SUCK with a 2871r.

I'd stick with something pretty mild to match up the cams to the good mid range punch of that 2871r. Either a 3653 or 3651. We can source them for you, they are available either in cast or billet.

[salz2135]

cat
schrick
and revolver are some brands to start looking at.

are you going to tune for the cams or just drop them in?

[slopoke]

tune of coarse.. I want the most out of anything i throw at my engine... Rough estimate what do these cams cost?

[Pete@IE]

Most are between 5-700, although billets are a bit more. I wouldn't bother with a set of billets for this application though.

[salz2135]

what are the advantages to billet over cast?

what are you tuning with?

[slopoke]

ok not as bad as i thought being they are made across seas, thought you were gonna tell me $1500+... Hmm i'll get back to you though thank you very much... Oh and where can i look at specs of these and see what rpm range each set affects, also do i need springs/valves/retainers or oem ok?

[slopoke]

what are you tuning with?

Havent decided i was thinking unitronics any recommendations?

[Don Supreme]

Good luck finding a good strong resource on what these cams really offer, but I would get the 3653 for your setup...

What year is your car?

[Pete@IE]

FWIW, i don't actually know anybody that really has a custom tune for a set of cams- other then guys on standalone... Luckly, the ME7 does a nice job of sorting things back out. Idle and such always needs some tweaking especially the idle torque to get them to idle nice.

The billet cams are quite a bit stronger, and there is less chance of problems- voids, incursions, or other possible issues with a casting. If you had a 35r or something and were gonna build the head and rev it out to 9k or something I would definitely tell you to get some billets- thats what I run as well. It only takes seeing one or two motors destroyed to a broken cam to justify the extra expense. That said, ALL the OEM cams are cast (GOOD castings mind you) and there certainly is no problem with that for milder applications.

thanks guys

Don... Its the same set-up as me (but most likely a 1.8L). He stated in the original post. Nothing bigger than a GT2871R.


I have the Cat Cams 3651s in my 2.0L and I'm running a GT2871R and currently getting a custom Motronic tune by ASP. You can get Cat Cams through Bob Quindazzi (qedpower.com)

[Don Supreme]

Yeah, but if he had a 1998-2000 he could run a bigger cam without worrying about variable valve timing (drawing a blank on the name of the technology) that the 2001.5+ have.

Plus, IMHO the 3653s have shown great gains on the dyno.

Good point. No VVT (variable valve timing) solenoid.

I was going to convert over to no VVT but went with the 3651s since BobQ recommended them to me for my application (based on how I built the engine and why).

[slopoke]

yes my car is a 1999.5... So what size would work best?

[dougyfresh]

Tough to say. What are the specs on your engine and hardware configuration? What are your goals for the car?

Like any mods, you need to have a plan and expected goals/outcome.

[slopoke]

basically car is almost stock right now... neuspeed exhaust, modded air-box, 3" tp, and giac ecu... I want to get everything done once and done right over fall/winter

[slopoke]

Basically i want to throw in:

Cams
2871 turbo
atp manifold
2step
clutch
AMAZING TUNE with 93 and c16/meth
and maybe a little 35shot from a wet kit laying around...

Fun track car and really fun DD!

your not going to get an AMAZING TUNE that takes advantage of the cams unless either

A. Its a custom ME7 tune
B. Standalone

[slopoke]

what is me7?

[dougyfresh]

what is me7?

Me7 is the 'Motronic' control logic that the factory designed to control the engine operation. Most 'flashes' are just a software upgrade for Me7.

Since you live in Georgia I would consider traveling to Alabama to the APR headquarters. I would be willing to guess they could custom tune your car. If not, Absolute Automotive in NC does custom Me7 tuning. Then the next closest is Autospeed Performance in NJ.


Is your motor an AEB? I forgot what years the AEB-style engine is in the A4. If so then your bottom-end internals should be okay for your plans.

Custom tune would be custom. How many people do you actually know running a truly custom tune and not off the shelf? I run a 100% custom tune that accounts for my AEB with VVT and Mild Revolver CAMS. Not one person on here with a GT30 or larger has a similar setup that would allow the tunes to account for static similarities in all cars, hence we all have different tunes some 100% custom and most off the shelf with no DYNO or Street ME7 programming done.

#1 99.5 is not me7 its the previous ecu ME5 (IIRC)
#2 -------------------- You can forget running c16 or meth @ full potential without some motor work.

The 2871 will blow your stock motor (rod pop) if you try to max it out (i.e. true c16 tune).
Did you say something about spray ------- HECK NO!

Stock motor + 2871 + spray = (INSERT EXPLODING BOMB)

THANK YOU.

Can you come over to the B6 A4 forum and say that??


I am getting a 100% custom Motronic (Me7) tune written right now. Optimized for my hardware configuration (2.0L stroker, Cat Cams 3651s, GT2871R, HFC, 3" MAF, OEM intake mani, AMU small port head)

[slopoke]

Im lost wont c16 and meth help from detonationg?

however i figured if i decided to spray35-50shot i would upgrade the rods first, and yes AEB

[Don Supreme]

true c16 and or meth tune would make MORE POWA!! :-) than your stock rods could safely endure. It would pop sooner or later.

With your AEB, you're probably going to want to swap out for stronger connecting rods to reach your goals.

(Someone please correct me if I am wrong. I am not entirely sure of the strength of the AEB internals.)

[slopoke]

i said i would upgrade the rods if i decided to spray it but with just a 2971 + bolt ons i should be fine

I don't quite follow what you mean? Custom tune to me would be a tune that somebody has gone in and edited the maps on a dyno or some combination of dyno, street, and track.

Almost nobody has that, and very few people can do that, like I said- mostly just guys running standalone. Do I think its really necessary for most setups? Absolutely not.

That's the general consensus of being Custom. Most would do some serious dyno time, then street/real-time tuning. Dyno's are great, but the real world is where I play.

Unitronic does that. Ian has a custom tune. There isn't a shelf tune for his turbo, and what appears to be a very nice tune as well.

If or when I build an engine I would do the same thing. I'd have a shelf tune loaded so I could drive it to Canada, and let them have it for a couple days. I've always wanted to go to Canada too.

[Pete@IE]

Haha, ya, unitronics is SOOO far from here that I always forget that is even an option for some people.


PS: But, we do use their off the shelf software and it does rock :)

[quattro16]

I might be taking a drive.

I've been very happy with my Stg1+ flash, and I've talked to a couple people outside of the B5 world that love their BT/BAT custom tunes. The choice is made for me, if/when I get there.

It's an option for some. The midwest guys through PA/NJ/NY all have about the same drive... and need a passport.

[Wizard-of-OD]

Ot biggest i plan on goin is gt2871...

Why?

[slopoke]

just looking for something that can run 12's at the track and still be fun on zee highway w/o a ton of lag

[Don Supreme]

Issam does not approve of the 2871........... He says its weak....

[slopoke]

HAHA this is my DD so i dont want crazy lag and i dont want a PITA clutch

[slopoke]

one other question will my 3" atp tp bolt up to the 2871? Or do i need some kind of adaptor or a custom tp?

http://www.ecodetuning.com/shop/cart...t_detail&p=671

when you run a larger turbo ie. 2871r there is more TP per say its all incorporated into the DP which is either v-bolt (your best bet) or 4 or 5 bolt discharge.

this is the correct ATP one:

I suggest you read the FAQ and search more before you get yourself into this project. you have a lot to read up on
