Ok so I've gone back an forth from wanting to turbo the 16v or leave it stock a number of times to full N/A or leaving it stock(coin coin). And seeing that Benz master has a tubular manifold available I think maybe I just might. I've done some research on egay turdblos(nick name from a website I saw for ebay turbos :xxrotflmao:) and found that the brand " GODSPEED" is actually not to bad since they are ball bearing water/oil cooled. The turbo I was looking at is a clone of a GT28 with an AR of .64 which at 8 psi tops 10 is about 45-60% of what it can handle adding to safety factor of it not blowing up and destroying my engine like many have heard from kids buying them and maxing them out on ricers. Could a smaller turbo do just fine maybe a .43 AR or would that just push hot air at red line?? So with that I have comprisized a list that is very easy to change if anyone has better Ideas that stay within a budget cost.
GSP turbo GT28 clone .64AR-$300
Intercooler kit - $185 (includes a way cool BOV lol)
oil/water cooler lines and fittings - $50-70
benz masters header - $900
Misc i.e header wrap turbo blanket etc - $100-200
Total cost= $1535-1655
Now Ive recently ordered Silver's EFI kit and its awaiting my install when I return home on leave from Afghanistan in october. I ordered 315cc injectors, accel coil, MSD DIS ignition box (end of the month), magnacore wires (a must with the MSD) and a 325i TB ( he tossed in the adapter plate for free :D ) My question with this is will these injectors be able to put out enough fuel to run at 8-10 psi. Ive read in a few of the turbo builds that 10.5:1 is high comp and not good for a turbo which from what I've been seeing in other markets they are running 15 on s2000's which is 11.5:1 so I dont think that is to big of a deal if tune properly. Also mosselman of course was running 7psi just fine back in the day.
For the oil/water cooler lines 2.3euro mention in my other thread that I could t fitting the oil pressure sensor for oil with a restricter fitting in between and tap a hole into the pan for the return line. Is there by chance an oil galley freeze plug on the exhaust side i could pop out instead?? For the water line hook ups could using the copper line the runs from the rear to the front of the engine by the intake work for this??
About 10k ago I pulled the motor because I was bored and had a second car. when I pulled the engine apart(leaving the short block together) I found the cylinders in amazing condition for 96k miles and the valves were very clean. Plugs have never looked bad just running rich build up on them so this leads me to believe the engine is still I good running order and a leak down test will confirm this. I had installed a new head gasket, chain and guides as well as pan front and rear seals since the engine was out.
Please feel free to post your opinions but bear in mind as I will be doing more research I'm not spending 1300 on a turbo i can throw 50 yards lol If this was my cummins and its was a 62mm turbo that would be a different story. so other then that feel free to through out some ideas.
Thanks for the input.
