thanks for your input guys. However, i have seen many k24s with a type r gearbox for example the EG civic from JDMyard has a similar set up.

So if i used a CU2 gearbox, can i jus swap the internals? or does it need a full gearbox replacement. And as i mentioned, i would also like to install an LSD, which one should i use and how should i go about integrating that with a Cl9 manual gearbox. I believe changing to a JDM dc5r lightened flywheel and HD clutch is a very good investment.
