You have take your old one out and send it in to them go get it bore out. The ebay id was conceptillusions. They did the work for me and also free powder coat form 6 different colors to choose from. But about that modern performence throttle... i heard alot of great reviews in dsmtuners.com. Everyone that bought the throttle said it pulls and it cost around $220 and for a better gain bore out your intake manifold to match the 60mm. |
yeah....the reason I asked is because my head is ported and polished along with the intake and exhaust manifolds being gasket matched and ported to the same port size of the head. if i got a bigger throttle body, it should drastically improve airflow.
