Hey im a newb in the a4 world. Im thinking of replacing the stock 1.8 engine with a new engine. Any ideas on where to find a new block. Thanks for the help.

 

What is wrong with your current engine. It is pretty indestructable.

 

Up to about 450whp... If you're planning on running over that. Give Golden Eagle a call, they'll be more than happy to build you a block that's guaranteed up to 70psi.

 

70 psi . That would be awsome. Good luck finding a turbo that can hold that and that the 1.8T would be able to actually spool up

 

GT42, or the GTB100. I've got friends with DSMs that are running 40psi with GT35Rs... On stock block. [:-]

Chances are, I'd probably get 84mm or 84.5mm pistons with 8.5:1CR. 2.0-2.1 with that low of a Compression Ratio... Mmmmmm... Fun.

 

Yeah, I have a buddy that has a MR2 that was actually running 60psi, I can't remember what turbo he was running but he had to tune it down because he kept braking axles and trans.

You think the stock trans could hold the amount of power and torque 70psi would produce?

 

Anyone got any website links for audi engines. My engine is going to have about 50 to 60 thousand miles on it, i want to start fresh with a new block and upgrade the turbo.

 

What year is your A4. Your idea odesnt make much sence. If you want to upgrade the turbo and plan on doing the work yourself I take it, I would test it on the used engine before I blow up the new. Plus it is much cheaper to rebuild the engine then buy a new.

 

Do you have any clue how much what you are trying to accomplish costs? You are talking about spending almost as much as what the car is worth in upgrades/mods. You dont need a new block with a BT upgrade with only 50-60k miles. Just get the mods done, if your engine breaks, THEN get a new block.. Your theory doesnt make sense at all.

 

Anything over 20psi is dangerous for the street, anything over that should only be used on a track for 1/4 mile runs, or on a car with a 6 billion$ engine... the heat produced above that is too much for the cars to handle, any cars. If you want to produce the power you are looking for, get a bigger turbo, make up for the air pressure with volume, because in the end that is the goal... to increase the volumetric efficiency of the engine, and with forced induction, for a general rule, 1 bar (14.7psi) will double your v.e. If you use that kind of pressure, you will FRY everything around the exhaust and turbo... Watch your EGT's
