I have been reading all this posts, but nobody mentions lowering the compression on the engines. I would like to what would be a good compression for a turbo in a d16y7?

thanks, MrBLuR

I assume you are talking about a built motor.

It depends on what your power goals are, what kind of racing you do, what kind of turbo you are using, etc...

Generally though, I like my motors no lower than 10.0:1

 

Agreed!

 

I'm just curious what you guys are doing to make these 10:1 motors survive with high boost? If your not running high boost, why not? If your building a motor it makes a lot more sense to put some reasonable pistons in it and run 18 psi than to put 10:1 and run 8-10.. 18psi and low comp will be much faster.

 

Lots of tuning. There's been quite a bit of discussion in the past of high compression, lower boost vs. low compression, higher boost.

 

building a turbo from scratch I just picked up a mitsu td05-12a turbo from a starion ($50.00).Sending it out to get it rebuilt $250.00. next is the manifold and downpipe thinking of giving drop shop a call. to lower compression I was thinking adding a gasket from mrgasket or ? any suggestions?
thanks in advance, MRBuR
