Swap requirement

[pilks]

Im seriously thinking about doing a pi swap on my 98 gt

i have a few questions

1. Will I need a custom tune from a dyno shop?

2. Will i need to run 93 octane fuel?

3. Can the car ever be supercharged with a pi swap complete?

Thanks

answers in order
1. It will help
2. No, the 99 and pi cars arent required too so why would yours.
3. Yes, there are plenty of supercarged 99+ cars

if you are talking about 99-04PI heads on a 96-98 block:

1: highly suggested
2: suggested (higher compression ratio)
3: yes, with lower PSI and retarded timing you will be fine with boost on a PI swap application.

if you are talking about swapping the entire motor:

1: not really
2: no, mid-grade will be fine
3: yes, without a problem. you can run more boost with the lower compression ratio.
