You go from modding to your 328 to a 135 or 335 in a year?

Yes, we are talking very serious money there, nonetheless ..... there is nothing better than N/A R6, is there?

I prefer n/a zx-6r 636 over the n/a r6.....Kawi is king

That's too bad.

I did. Could not stand running at 4000 RPM and above more than 60 percent of the time when running in a 330 so replaced with a 335 that I stumbled upon...I actually got better fuel consumption too. Better than modding a high mileage NA engine. Not a fan of waiting for tow trucks.

I get it. I don't quite understand how OP changes his tune so quickly in the thread. I'll gladly take a faster BMW but waiting to see what the M2 is all about in a few years.

Currently I'm ~275hp at the crank.

But I weigh 2991 lbs in race time.

hp/weight - 0.0919

Typical HP/weight of a stock 135i

hp/weight - 0.0882


Yes, there is the whole argument of I can make a 135/335i faster blah blah. However Headers/Tune/Exhaust is a lot less than the differential to purchase a 135i

How much did it cost you to get that weight? I'm considering it but it's expensive man

Stock curb weight for my car w/ 1/4 Tank was ~3100 lbs

APEX Wheels (now soon to be Kosei Wheel)
Recaro SPG Seats (Can easily be done with any other Race Seat)
VAC Mounting Hardware

Couple grand at the end of the day. I have around probably 10-12k in my total build. I still need to pickup a 15lb Battery

It helps I don't have a sunroof at all, no options besides M Sport Package

[Rival]

intake
headers
exhaust
3 stage intake mani
50-75 shot or super charger.....pick one.


or sell for a 135/335

300bhp really isn't unrealistic. we have 3 liters and a good flowing head with a reasonably solid bottom end. but few here would do it anyway - I mean, some guys pay to have an air filter installed in their car. a full engine build beyond bolt-on mods is beyond them.

I'm really waiting to see what pete's cams do. I wish we could get at least 11mm of lift and maybe a 270 degree duration, but that's probably not possible with a regrind.

for high RPM, high power, you'd probably want to ditch the stock intake manifold as well.

[HouseN54]

200 shot, done.

[pavproch]

Well, I happen to know a guy with e92 330i (N52 EU specs, stock 190kW ie 258 hp), heavily modified (both HW and SW) within a range of 30k+ USD (spent on powertrain only...) who dynoed approx. 340hp (shaft) with 100oct .... but the car isn´t street legal (emmissions compatible) anymore...

Definitely doable but as you mention it's very expensive. Can be street legal depending on where you live.

Well we'll find out next week anyway. Then you'll get the stock cams to profile. At least this can qualify as a bolt on for the more skilled DIYers.

I hope there are good results because this will be my next endeavor if we see some gains!!! #hope

Yep, here's hoping. Not too worried but it's never been done before so, ya know, risk and all. The cost of the installation is high so I'd suggest finding a competent indy even though that kinda adds to the risks, too.

You know adding things onto your car is not the only way to make it faster, and there are not many ways that can make a noticeable improvement on a N52 (mostly placebo effect). But OTOH, taking things away can also do the trick. A lightweight car does not need as much power to be as fast as a heavy one. Get rid of oversized rims, change body panels to carbon fiber (genuine, not vinyl), get rid of those back seats (front seats too and replace with carbon fiber shell seats), remove sunroof, replace entire exhaust system to Titanium, etc.

Titanium? It's cheaper to have a custom thinwall 304SS (or 321SS if turbo) exhaust made.

Free flow intake, three stage manifold, offroad tune, headers, race exhaust, cams all produce real measurable power. A race clutch and LSD will get it to the road faster and less will be lost to windup if the driveline is made rigid with the correct mounts. What improvements are placebo effect?

Oh yeah, forgot to mention it's possible to reduce the weight by four to five hundred pounds without resorting to CF body panels other than hood and bootlid. A CF roof doesn't save any weight but a sunroof delete does. Most of the weight savings in changing the hood and bootlid over to CF covered FRP is the loss of all the hardware for the latches and remote opening mechanisms by replacing them all with locking Aerocatches. Getting rid of the carpet and the really heavy underlayment saves a surprising amount of weight by replacing it all with Koolmat and CF/Nomex honeycomb floorpans. There's also lighter batteries and gutting the trunk as well as removing the back seat. Changing the front seats to fiberglass shell race seats will save anywhere from sixty to seventy pounds, nearly a hundred if the SRS is removed in its entirety. The headliner and the pointless overhead consoles can come out along with all that heavy copper wiring as can the telematics unit in the trunk along with the pointless sharkfin antenna. And the car is still perfectly legal, complete with air conditioning. Lighter wheels and tires is a given.

my headers are definitely placebo effect

edit 900 posts..whatchu know about that!
