How about exhaust? I doubt anyone who is going to spend almost 30k on a blower and built motor is gonna be on stock exhaust.
At 700whp will the transmission hold up? Might need a rebuild as well as stronger axles.
It’ll probably need motor mounts, diff mount and trans mount as well.
Suspension upgrade at this point is a must, as well as some type of brake upgrade. Basically you’re putting down 2.5x more power than stock.
He included exhaust (exhaust + clutch for $5k).
Brakes and suspension is a personal choice but not mandatory for straight line power.
All mounts added up together don’t even equal $1k I believe.
As for axles and transmissions, can’t speak to that. I honestly wouldn’t know.
Didn’t see the exhaust, my bad…
Brakes and suspension are mandatory when you’re pushing 700whp+
The trans and axles will not hold up to multiple 700whp+ AWD launches.
Tell me why they’re mandatory. I would personally upgrade them myself, I even have for way less power but I don’t see them as being mandatory. And last I checked, the RS4 had 8 piston brakes stock. Maybe start a new thread 
As for the trans and axles, probably but untested.
Watch the launch of the race gas APR RS4 and anyone with any drag racing experience can tell you that the car is in dier need of suspension…
The stock brakes sucks and if you plan to make 700whp I assume you want to drive your car hard, correct?
What do I know thought lol, what I’m trying to get through hear is that building a car is never that simple. It’s never as easy as listing three mods, ordering and installing. There’s always a million and one little things that add up and end up being a decent amount of extra cash…
Guarantee you that you won’t be able to drive a reliable 700whp RS4 for under 50k in mods, it won’t happen.
Seems most of the super power cars I’ve seen are pretty soft suspension wise.
Besides the Apr car had stock cat back and suspension and went 10.6. I think it’s doing just fine. The suspension was not an issue.
I thought you were saying ‘just buy a gtr’ as a financially better option than a motor build.
Those gtrs from America with mods are interesting. The first one is trapping what a stage 2 RS4 does, never mind stage 3. The second one is slower than what I think the built motor rs4 will do.
And they are gtrs .
What year are those by the way? Are they early models? I was under the impression that the gtr was a bit of a China doll in the early year(s). If you’re showing 2011+ gtrs with modest mod lists, shouldn’t you be starting at around $80,000 for the car? Won’t the early cars need a good bit more work to keep up?
The 10.5 car is a 2014

So that’s what… $125,000+mods?
The second car had drag slicks, a carbon fibre trunk, a spoiler delete and who knows what else.
So I think your reply to my off-topic reply is off-off-topic 
The 10.6 run had no Catback and high flow cats.
Suspension IMO def held it back, it needs to be stiffer- it’s sloppy.
lol that’s right they took the cat back off.
The 09 issue was the LC. It dropped the clutch at like 5-6K to get that crazy 0-60 time. People were doing it all the time and that would lead to the broken transmission. Part of the way through production (in 09) they removed LC to fix the problem. They added it back in 2011 (I believe) but reduced the rpm and put safe guards in to prevent overheating etc.
As for 12-14 models the inlets and high boost was the only change. Both are included in the SBD700 kit package.
Here is another link to an 09 SBD700 running 10.8@134 on pump no other mods and without the P&P intake manifold:

If you notice his 60’ it’s terrible… Lot more left in that car ET wise…
Edit: What would really be nuts is if the SIR stage 1 turbo upgrade was still available. It was $2500 for the upgraded turbo’s and that would get you into the 9’s.
Before I bought the M I was seriously thinking GTR and I actually got a quote from SBD for a full built 1,000hp GTR (built engine and transmission with labour) $30k! Pretty crazy bang for your buck…
Edit2: I have to stop looking at the market section on GTR life it’s really beginning to get me depressed!
Here’s an 09 with basically the SBD700 kit for the low $50’s

Spend another $11k and get a built engine and transmission good for 800wtq

A few extra grand and you can get SIR stage 2 turbos and run deep into the 9’s
[quote=“euroswagr”]
thats the ticket… I wouldnt just give up and say the motors can’t take it, too much compression. there is a component failure if a motor is having longevity issues. rings are a fairly common issue, an FI motor and an N/A motor are going to have very different ring designs/specifications from the factory. if its not an obvious failure like a rod that looks like a ? or a obliterated piston from pinging, I’d look at the rings next.
I’d personally skip the compression lowering gaskets, the FI motors seem to be particularly sensitive to the design of the combustion chamber to ensure proper mixing. I’d be concerned that moving the head up without modifying the combustion face of the piston could cause issues with mixing.
Yeah, the RS4 should upgrade to Brembos if it gets a bunch of power.
Oh wait…
That’s kind of what we’re talking about here. Around $30,000 in modifications.
My math was wrong above. $69,000 for a built RS4, stage 3, full exhaust and stage 5R clutch/pp/flywheel.
And it’s an RS4. You can drive it to work. You can take your kids to school. You can go out in a monster snow storm. You can do whatever you want, and your interior is luxurious and comfortable as hell. You won’t be embarrassed to drive it. You wont attract unwanted attention and have every ricer on the street trying to race you. You will just go about your business, and murder any car you come across. Pretty cool.
Frankly that’s the case with stage 2 as well. What car out there is nearly running in the 10s that you see on the street? I mean I know there are 10 second hondas and whatever else, but do you see them on the street, or do you see them in magazines and on trailers?
Yeah, I was considering a GTR (i wanted it so bad when I first heard it’d make it to the US when I was finishing up college).
I still think about it and look at GTR Life (formerly NAGTROC).
While it’s less of a performance beast (though by no means a slouch), I’m happy with the RS5. Beautiful inside and out and packed with lots of tech.
That and I don’t need to recreate a wealth of knowledge outside the Audi scene (finding a good shop in the area, tuners, etc).
Your car is sickeningly perfect. I can’t imagine wanting a GTR more than your Sepang RS5. Going nuclear speed is fun, but it’s not like your RS5 is 0-60 mph in 7 seconds and 15.2 seconds in the quarter mile.
You car is as fast as a Ferrari 360 Modena. It’s ridiculous.
And as we’ve seen now with 3 kits that should migrate their way into the RS5 world, for between $12,000 (JHM) and $20,000 (APR) you can be 2014 GTR fast. That’s hard to argue.
I find the GT-Rs to be extremely overrated. I had a nicely modded one, sold it, and don’t miss it a bit. The car was obviously very fast in a straight line (mine was 650ish whp on a mustang), but other then just was completely uninspiring. Anything 6/10s or under and it was pretty boring, and how often do you honestly drive over 6/10ths on the road. The rs4 is so much more enjoyable to drive, has worlds better fit and finish, and with a s/c would be in a relative league of its own for awd “muscle” sedans.
I agree the RS4 stage 2 or 3 would get you a fast sedan that would be more practical for everyday use than any GTR. However, it won’t out perform the GTR even in stage 3 trim.
Not so sure it won’t outperform the GTR. We’ve already seen it pretty much match the GTR in stage 2 trim (and APR’s 1740 kit trim). I mean if you want to post more videos of stripped GTRs on slicks, I can’t speak to that. But if we want to compare these cars in street trim, let’s do so. It will not be easy for the GTR as you’ve outlined it. I’m not even sure what gas you’re talking about in the GTR. I’m strictly looking at pump gas for the RS4. Should we add the race gas to the mix on the RS4? Remember the JHM car is threatening the 10s on 93 with stock fuelling lol. Want to give it upgraded fuelling, and some octane? You’re looking at it trapping 130 MPH, on street tires. This is stage 2 remember. This is not with carbon fiber trunk and hood and slicks and a gutted interior or anything. This is a 4 door 4 seater RS4 that you can drive to work. Stage 3? Sure, lets give it anothher 100 whp or so. You still don’t think it’s going to match or outperform the GTR???
The JHM stage 3 will either max out the V3 Si or get a bigger blower. The V3 is capable of 1150 CFM. You’re talking about 700 whp there…and if they’re looking to go even bigger?
I think we both feel the same way. I had a few cars I was looking at including the GTR and RS5. I chose the M3 as it was the last chance I would have to own the first and last high revving V8 engine BMW will build.
I do on occasion feel it be cool to have a ridiculously fast GTR but something about the fit, finish, and overall balanced performance of the higher end German cars that out weigh the ridiculousness of the GTR…
A few posts back I made a second edit. In that post I linked a sale on a GTR with basically the complete SBD700 package for $51k. I also, linked a deal where you can get a build engine and transmission for $11k which would be good for 800wtq and much more whp. Last link show a car with similar mods plus a stage 2 turbo upgrades ($3k) and it was pumping out more than 900whp and ran 9.1@145mph. So for about $65-70k it is possible to have a 9 second GTR. That, to me, is insane performance!
