As you can see I basically have a full on race motor minus a few parts.. up until recently thats what I wanted to to do it, But now I have discovered the world of autocross. Problem is the Yo nasty turbo for big par had a ton of lag which is bad for autocross. and the 14b is quick spool so it is good fir autocross but too slow for par..

I figure best way I can go at this is to spray the piss out of it and make it quick with the 14b..


given my mods how big of a shot do you think I could run?? I am leaning near 100 safely prolly more, but I fell the compressor will be overrun..

set the boost down a lil bit because its gonna creep!, and id say try a 75 shot, it should give you about a 100hp gain, theoreticaly.....

That's actually what I plan on doing. Coupling a small turbo (14b) with about a 50/75 wet shot of nitrous. Should make the car pretty quick.

It's going to creep bad with that small turbine housing and wastegate. If you want quick spool ont eh spray on that turbo, consider going to a Tial 38 or 44 external.
