Get on idi forum on here. And post similar. If your serious about this and have done that much all ready. U can push more fuel then these motors will handle with a modded DB2 pump. A stock size idi turbo is not gonna run it with that amount of fuel. Probally go to something like the first gen strokes had or larger. Lag wont be a huge issue if ur comp only.
Put a 4000 gov spring and hammer down. Studs are a must though.
