    When we designed this catch we wanted to have the most function options available, the best separation method, and the easiest to service. The Turner engineered catch cans offer a pre-setup design based ion desired flow direction, however this does not limit you to this flow. The inner baffle orientation can be easily adjusted to flow in both directions in case you decide to move this catch can to a different vehicle. A 4 chamber system baffle system inside the catch can was engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can. Having a closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation.

    Our catch can was also designed with the idea that the cans fill level can easily be checked with a top mounted dipstick and an optional use bottom drain hole. The drain system comes complete with a valve and hose to be mounted at a lower area of the vehicle so when you're doing an oil change you can drain the catch can.

    Features:

    • 6061-T6 billet machined body, anodized black for lasting protection and appearance
    • Strategically positioned 4 chamber baffle system maximizes oil / air separation
    • Knurled and black anodized oil dipstick makes inspecting oil volume of reservoir clean and simple
    • Sealed with a pre-installed viton O-Ring
    • Includes 2.5mm allen key to remove baffle plates for cleaning
    • Engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can
    • Closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation
    • Optional use drain hole - drain kit included!

    These studs will save the day! Stripped or corroded exhaust manifold studs are a major pain to deal with. Rusted studs fuse themselves to the nuts and back out of the cylinder head. These are M6x35 stainless exhaust manifold studs with new copper nuts that will make your manifold install a breeze! These studs have an internal 3mm hex so no more "double-nutting" or stud installers are needed, so no more galling threads! These have been a best seller for us since the late 1990s!

    A MUST for every E30 M3! This is the first and most important modification you should make! During hard cornering/long sweeping corners the engine oil moves up the sides of the oil pan causing oil starvation! Oil starvation is a very common cause of engine failure in E30 M3's without a baffle. Our easy to install oil pan baffle kit keeps the oil near the pick-up and therefore reduces oil starvation. Our baffle along with the engine oil filled up 1 pint above the top mark on the dipstick with a quality synthetic oil will help insure a long lasting M3 motor. This baffle is a one piece unit, not a modified, welded stock baffle. No core charge! Includes detailed instructions. Lower oil pan gasket included. Installs in about 1 hour.

    Trouble trying to get your alternator tensioned or aligned properly? This is a common issue due to the rubber bushings wearing with age or degrading from exposure to the elements, oil, or other contaminants.

    Restore proper alignment and tensioning function to your alternator with these Heavy Duty Alternator Polyurethane Bushings.

    These will resist pressure and any possible contaminants for much longer than stock rubber bushings, making these a likely one time solution to your alternator issues!

    One of our most popular items! We have been selling our S14 stroker kit since 1993. Since then we have sold HUNDREDS of this exact kit, and have received incredible feedback from our customers. RELIABLE Horsepower is our goal. Our E30 M3 2.5L Stroker kit uses factory BMW Evolution III parts to convert the stock 2.3 liter engine into the Evolution III 2.5 liter engine. Increasing the displacement and raising the compression yields much more torque: +50 ft/lbs @ 4000 rpm. With a stock head our 2.5 kit will make over 225 hp.

    Our kit includes everything you need to convert your 2.3L into a 2.5L. We highly recommend upgrading the intake and exhaust system to allow larger 2.5L engine to breath. Call for more details and for "custom" packages. We can set you up with any other engine components you may want to replace (tensioner rails, chain guides, oil pump, etc) at the same time. For your benefit, we carry all these items (and at a great price).

    The Turner 2.5 liter S14 Stroker Kit includes:

    • Genuine BMW 2.5L crankshaft w/ bearings, nut and spacer
    • 2.5L head gasket
    • Bottom end gasket set
    • Turner/Conforti Custom 2.5 Liter Computer Chip **Only available from us! This is what sets our kit apart from the "other guys kit"
    • Wiseco 2.5 forged piston set w/ rings (11.25:1 compression)
    • Genuine BMW rod bolts and head bolts (we suggest Genuine fasteners for reliability)

    Our racing fuel injection upgrade for the E30 M3 2.5 consists of four Evo III fuel injectors, Evo III Air flow meter and custom calibrated performance chip. This kit was originally designed for use on the TMS 2.5 liter engine conversion with: Stage 3 head, Schrick cams, Evo III header and straight non cat exhaust but has been a successful upgrade on other variations of this set up. The addition of these components adds the ability to supply more fuel that the 2.5 liter high performance motor demands. Choose from 7800 or 8200 rpm redline (For off road/race use only).

    Kit Includes:
    1 x 13621466349 - Air Flow Meter
    1 x Custom Turner Motorsport Peformance Chip

    The timing chain tensioner from the 1995 E36 M3 is a great upgrade for other Motorsport models - 1988-1991 E30 M3 and 1989-1995 E34 M5! This tensioner virtually eliminates the cold start-up engine rattle so common with the S14 and S38 engines. It makes the whole engine quieter and smoother. Any new tensioner will accomplish that but the S50 tensioner has several new features that make it superior to the original design. This unit also has a internally loaded spring, so installation is much easier than the old style tensioner (no need to squeeze the spring and hold it while installing). Includes oil seal ring (not pictured).

    1985-1989 E24 BMW M635CSi M6 - M88/3, S38B35 engine
