Hey guys, quick question
- Thread starter ebelizard

I would not remove the air filter box until AFTER you get a CAI. Make sure too that you get a CAI with a heat shield, if you do not and if you remove the box before getting the CAI your going to be sucking hot air into you engine thereby reducing performance. I would get a CAI, exhaust system, and chip. Best of luck to you and welcome to the board.
THESE ARE MODS I HAVE IN MY CAR I HAVE TO SAY THIS WAS THE BEST MONEY I EVER SPENT HOPE THIS HELPS!!!
The Bbtb/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 -25bhp, typically
giving around 218bhp on a 328 and around 193bhp on a 323.. 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 second hand M50 manifold. The
modified manifold has a new custom made 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. The manifold comes
complete with the previously used seals that came with it. Though you might
prefer to buy new ones. I can supply new seals at £25 for a set of six. 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 you have 'ASC', 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.
E39 5 series models require a Pas reservoir relocation bracket at £15. I can
supply a brand new manifold instead of a second hand one at an extra £210. You
can retain all your old parts for an extra £115.
This conversion has to be easily the best power per pound that you can buy for
the M52 328/323 engine. The engine revs all the way to the redline without any
hesitation at all. Whereas the standard engine struggles from 4,500 revs.
The cost is £325 without traction control or £375 with traction control. + £20
postage. I can fit the kit for £100 (In Essex)
I can supply the throttle body on its own whichcan 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.
In Summary
Bbtb/manifold kit £325 with exchange throttle body.
Bbtb/manifold kit with ASC (Traction Control) £375 with exchange throttle body.
With both of the above options, I will need your old throttle body and plastic
icv chamber/seal returning to me after fitting. If you have ASC, I will also
need the ASC unit.
Pas relocation bracket for E39 5 series £15 (Not required for E36 323/328)
If you prefer to keep your old parts, please add £50 for the throttle body, £50
for the ASC unit, and £15 for the icv cover.
The manifolds are second hand. If you prefer a brand new manifold, then please
add £210 to the overall price
New manifold to head seals are £25 per set of 6.
Fitting is £100
Postage is £20

He already has an M50 intake manifold. And a big bore throttle body seems dumb to me unless you also bore out the exit of the intake elbow where it's attached to the m50 manifold.
As stated by Big Daddy, a Cold Air Intake is a great idea if you're actually sucking up cold air. This means chosing either an intake that reaches down below the headlight near the fog lights, or choosing an intake in the engine bay that comes with a working heat shield. Seeing as how you're from Connecticut, i'd recommend the engine bay intake + heat shield.
I'd recommend getting a cold air intake, a cat-back exhaust, and software tuning. The CAI and exhaust will give somewhat limited gains, but I believe when combined with the chip and premium octane you'll feel quite a bit of added power.
