E92 coupe, auto, 150k or so.

What are you guys driving?

I just installed Chinese 16T's and so far I love them. What are your power goals?

Vehicle Virals on YT just had the DR700 kit installed but with a 62/66 turbo. If I had to pick a kit right now I'd go with the Speedtech. If you went with a Borg turbo it's even cheaper.

I thought they were stage 10? It is hard to keep track.

I went ST and never looked back. Sounds amazing and no twins are going to make 800whp.

If you don't mind, do you have a log?

Would like to see how boost builds on a 7 or 800whp ST

I'm just running 93 + meth right now. 21psi zero corrections. Full E85 this spring once BMP has their FF charge pipe in stock etc.

But you can google N54 6466 dyno and plenty of results some up, a few with logs.


Here is an example:



Looks like 25psi at 3800 rpm:

Thanks mate, seriously impressive, I thought it'd have a lot more lag low down,

Mid 600s, ideally. More than that becomes a whole pile of supporting mods. As it is, this is gonna cost me $2k in fuel and ignition support to make the power, but passing 650hp means trans issues and diff issues and a pile of everything else issues.

I'm shopping an FD right now so I really don't want to go nuts; I work from home and will continue to even once COVID is "over", so I don't need a real daily. Just something more reliable than fiery doritos making 400hp on a 30 year old chassis. I love my brap, but in goes the boost and out goes the apex seals, even if you get the Goopy 2mm stuff.

I won't say cost is no object, since I do want to control my spend here, but I don't mind spending a little extra to get the kit.

Wedge recommended:
Speed Tech kit with 6062 or 5862 Gen 2 (capped at 650 on the 5862 but faster spool)
Nexsys Ignition
BMP Stock-location manifold with 750cc injectors and top-mount line
Precision Raceworks Stage 3 bucketed pump
PR BMW BOOST REFERENCE HARNESS
MOTIV Re|Flex Advanced I/O Integration for AIC and FlexFuel

I'm going to go with what he says, because, well, he's Wedge. Not in a hurry to order, so it may be months (especially since I'm living in a hotel cuz my place flooded), but I'll post when I order it and so on.

IMO - going to a single turbo and trying to reach 650-750hp is for cars that are tracked.

Just my two cents

That kinda depends, you need to be a really, REALLY good driver to properly use 650whp on a track. And a very serious set of brakes to go with it. I'd think it'd be more fun on the highway or drag strip and I would turn the boost down for a track day.

Very much this. It'll be my street car, but mostly run on low boost in the 450hp range most days, and turn it up for highway shenanigans and events like the Texas Mile. Half-mile and mile runs interest me far more than quarters.

I have no intention of seriously tracking it, though I might do a track day here and there. FD will be more of a street-legal track car, focusing on responsiveness and following Colin Chapman's advice. E92 will not only keep its interior, it'll probably get added weight in the form of various equipment.

I've considered Cannonballing in it, I'm not sure if I want to put a second tank in the trunk or not yet.

A single turbo is not like twins, which build boost faster but you end up with much more top end and it is a bit more linear in how the power comes on. It is a bit of a trade off. Also, with most aftermarket twins on full E85 you want to limit the boost on a stock motor so you don't bend a rod at 3k making 600 wtq. As twins get larger and larger wheels you are trying to spin more and more mass which means the curves moves farther and farther to the right. A 10T it not going to be as responsive as a 19T turbine wheel, physics and all. ST also get better MPG and sound a hell of a lot better. That being said, different stokes for different folks. There are advantages to both.

I understand, there's always a trade off, agree ST sound better, I prefer the low down torque of the twins for dd, to be honest 400whp it's enough for me, not looking for big power,

is there a particular torque level, where you risk of bending rods on twins? I mean is the motor able to handle around 440lb/ft without bending rods on stock twins ?

Generally, yes. I'm parroting experts here, not being one myself, but my understanding is that the motor is going to around 700hp/tq or so. I think the bigger concern is that level of torque coming on suddenly at a low RPM, overstressing the rod(s).

What I know is that I'm going single, and Ken has assured me that my motor (assuming it's healthy) can take the power. He's my tuner, too, so he may be hedging the maps to prevent rod failure, too. I'll ask him next time we talk.

I’m 2 weeks on the new dr700 kit and only 21psi has gone through it at most. This kit has exhaust manifold fitment issues I experienced, and a leak at the weld on the coolant flange. And the new one, a big crack at the weld on the exhaust manifold between the turbo and wastegate which apparently is not so rare of an issue. Make your own decision but I want to sell it and get something better built

If you go single you have a lot of options. If you want the best kit, go with Motiv. If you want the cheapest kit then I think finding some ON3 or JP Workz kit will do. If you want the best bang for your buck go with Speedtech. If you want to burn o2 sensors go with Doc race.

I wouldn't get JPWorkz. I posted in this thread earlier. His kit takes about 3+ months if you're lucky and it's always sent half ass missing parts. I have a bottom mount 6266 from JP and I never got a chance to install it because I was missing the down pipe that connects to the stock exhaust with the 2 flanges. He simply ignored me for weeks and sadly I sent him $5 through Venmo so he can answer the phone and sure enough he did. Sadly he didn't even send the $5 back. I'm no longer installing his kit and I've sold it. Since then I'm sticking to twins since I already have everything for a twin setup and ordered a pair of RB 17T Game Finishers. Should be done within the next 8 days and shipped.

Your crazy! He has the worst reputation. My guess is 3 months later you recieved no kit or some parts only.

I just read the rest of the thread.
Sorry I couldnt help 3 months ago.

If you're in Sacramento, how are you passing the visual inspections? I get that your single is a bottom mount, but the plumbing still forces you to use relocated intakes, no?

Can you pm if you've got a guy?

Since when has this been an option? Anyone here running it?

OP are you getting the journal or ball bearing?
