Welcome to T ;) Its about time we had you on board Its awesome that you are taking a more n/a approach on things rather than choosing turbo straight off. You car is a really good base to work on, now you can concentrate on power. You won't be disappointed if you do go for the A series engines as you would have an ultimate response EP at the end of it. Costly but would be ultimate, also wouldnt be easy to handle so will need v.good braking upgrades. Give us a shout on msn jozman18@hotmail.com as I'm heavily into n/a tuning with a mildly tuned EP91 myself, I'm sure we would be on a similar wavelength. You can easily improve the SR with some nice little mods such as the corolla manifold I bet shell has mentioned to you before. Talk soon Joz
