Turbo conversion

Turbocharger system:
Maximum power 152bhp (316i)
Maximum torque 218Nm (316i)
This turbocharger system is designed primarily for two things. Torque and reliability! We use high response/low inertia Garret turbochargers that give superb boost response from very low rpm, which translates directly into very impressive acceleration in any gear at any rpm. Only the finest quality components are used such as high nickel content cast turbo adapter, cast aluminium intercooler, mandrel bent air pipes, silicone hoses, Aeroquip oil lines etc.
Thanks mate

Sounds good. The torque is what you'll like most. Who makes the kit? It seems from the ad, to be pretty well thought out. You probably can't go wrong. Make sure that the fuel system is tended to. You'll need more fuel in the chamber with the kit. Without knowing too much about it i can't say more really. Seems like a good add on if the price is right.
its sold by TDI and its 2k but the problem is i have spent alot on wheels and a kit etc so its cheaper to do the conversion rather than spend 4k on a good 320 and put the kit on etc, plus it will be different as i have seen no other bm turbos rounf my area, so will i notice an increase? and you mention the torque? how does that work, and also will i be able to fit a dump valve? thanks for your help
You will notice 50hp as well as the torque gain.
HP= torque*rpm/5252
as you can see, power- in this case, horsepower is dependant on torque. Torque is defined as force around a given point, in this case your crankshaft rotating center. 1ft/lb of torque is the movement of something of one pound of weight around an axis, 1 foot.
torque equals force*radius
All we really feel as drivers is the torque. Dynamometers can only measure torque and they then calculate horsepower. Horsepower is somewhat unimportant as you can see it relies directly on the measured torque.
If the torque curve is nice "and flat" like everyone here talks about, then you have an output that's very "usable" when matched to a gearbox so as to maintain that output throughout the engine's range as well as possible.
So, in real life, coming out of a corner in 2nd gear at low engine speeds, a motor with sufficient torque will exert enough twisting force on the crank axis to "power you out"
You can use a dump valve, or blow off valve (whatever anyone calls it) and should. The dump valve releases pressure between the compressor (in your case a turbo) and the throttle plate when you lift off the throttle. The plate closes off throttle, and without the dump valve the air flow and pressure which was built inside the pipes will abruptly stop and backup onto your turbo causing the wheel on the turbine to stall which some say will lead to premature failure but really it will just take longer to spin back up to speed once you're back on the gas.
Looking at the very small pic on TDI's site it seems that it comes with a Bosch dump valve as used on Saab 900 and 9000 models, as well as by Dinan on their supercharger kits. The valve is decent for low boost but leaks at anything around 15psi.
It looks like injectors and a fuel pressure regulator are included but the picture is small.

Thanks for your help mate, i think that i will start saving for the kit and plan to purchase it mid december, im also thinking of a ported and polished cylinder head, a lightened and balanced flywheel, performance cam chip, filter and exhaust, not at the same time as thats a lot to fork out in one go, but it should be quite a difference from the standard 102 Bhp, thanks for your help mate

the KIT costs 2000. what if you overboost? overheat? headgaskets, head resurfacing, your engine getting more water into the engine that you have oil. these things arent the cheapest or easiest things to do/get done. this will surely put alot more wear/strain that was never intended for the engine. btw, does the kit come with atleast something to manage your air/fuel? what hardware are you getting to manage the extra injectors? do you need ECU software?
Most low boost turbo kits do not require ECU modification, headgaskets to lower compression, or larger injectors. They typically use FMU ( which adjusts fuel pressure based on manifold pressure/vacuume) Some cheaper setups only replaces your stock fuel pressure regulator, with one that allows slightly higher fuel pressure to compensate for the increased air flow. There are many reliable kits out there that work on this concept. But I would also consider a 328 if more power is what you desire, as any forced induction will add points of failure.![[thumb]](/images/smilies/icon_smile_thumb.gif "Thumbs Up [thumb]")
