Meier1980, fikk svar fra han som modifiserer manifoiler og luftinnsugene, her er litt info om kittet.
(Så det jeg trenger er dette kittet til £375 + £60 i porto, og kammene til en amerikansk versjon av S50 M3 motoren ( som de gutta her også fikser ), inklusiv luftfilteret jeg har og en tur til sverige for å få remappet chippen, voila 236hk + litt xtra NM)
Hi.
Yes, I can ship to Norway for £60. I will also need £100 (£50 if you
don't have
ASC) deposit on the old throttle body, I will refund it when the body comes
back, or you can keep it if you want, and I will keep the deposit.
It won't need a re map, but it will help to give the car a bit more power. I
also suggest fitting the American spec S50 M3 cams.
Here are the details of the manifold conversion:
The manifold conversion is designed to remove the restrictions that BMW
deliberately built into the M52 2.8 engine. They did this to restrict
the power
to 193 bhp (the same bhp as the old 2.5 unit). The reason for the
restriction is
the German insurance market, which penalises cars which have more than
194 bhp.
However, the 2.8 has a much better torque figure than the 2.5 unit. It
will fit
all E36 328s and all E39 528s up until 1998 model. It will also fit he
323 /523
models with similar gains in bhp.
The kit takes about 4 or 5 hours to fit. The only downside after
installation is
the fuel rail cover cut outs don't quite match the manifold, though it
is barely
noticeable. Also a small piece of one of the fuel rail bracket needs trimming
off. Everything is reversible, should you ever wish to resort back to the
original.
Power gains with a free flow filter are in the region of 20 bhp, typically
giving around 218bhp. Tests have shown that this manifold will flow 275 cfm of
air as opposed to the standard 185cfm! Schrick make a free flow
manifold, which
costs £900 without the body! The Schrick unit flows 250cfm.
The manifold itself is an extensively re worked 2nd hand M50 manifold,
complete
with the seals that came with it. Though you might prefer to buy new ones. It
has a new chamber, screwed and bonded into the underside, which houses the
idle valve, air sensor, and oil recirculation valve in exactly the same
position as the original M52 manifold. There are also two new special
fittings,
which accept the standard M52 stabiliser brackets and idle valve cage. Also in
the kit is a big bore throttle body and if required, a big bore traction
control body. These are sold on an exchange basis, where you return your old
body or bodies once the kit is fitted. I will also need the plastic chamber
from your old manifold that houses the idle valve etc. The manifold comes with
a slightly reworked one already fitted.
This conversion has to be easily the best power per pound that you can buy for
the M52 2.8 engine. The engine revs all the way to the redline without any
hesitation at all. Whereas the standard engine struggles past 5,000 revs.
The cost is £325 without traction control or £375 with traction control. + £20
postage. Or £425/£475 fitted. (In Essex) Please add £15 for E39 5 series
models.
I can supply the throttle body on its own which can be fitted prior to
the full
manifold conversion. This will cost £120 for non traction or £170 with
traction
control. These are exchange prices, so I will need your old ones back after
fitting. The manifold can be added later. I can supply a brand new manifold
instead of a second hand one at £175 Extra.
