not realy, i guess if the turbo was too small it would restrice airflow and choke your engine, soo just dont use a turbo off say an old geo metro(yes they came turbo)
.
Ohh and if you need a turbo i should be able to get a handfull of t3eo4s out of a thunderbird tubo coupe for about 150 each, maybe a lil less depending on shipping.
