1. It's not a direct swap like Honda's
2. If he blown his motor, it makes sense.
3. For that $$, I'd get a brand new, bulletproof Motor then go for TT setup. He'll achive much better power, Torque, than he'd ever with the rb26dett.
4. If he didn't blown his motor, he can have his current one build up and go for FI. Still benefits better than swapping rb26dett.
