Hey can valves guides from the celica be used in my blacktop 3sge altezza?Get a Redtop, not a Blacktop. The Redtop was designed to be in our engine bays, wiring changes are minimal and extremely easy, mounts are the same as any Celica with an S-series engine, axles and shift cables are already in the car. The Blacktop is set up for rear wheel drive so you'll end up needing to buy a Redtop in addition to a Blacktop so you can salvage it for parts. It's a lot of extra work and a lot of extra money just for 10 hp, and not worth it at all. It has been done before. Check out the BEAMS Owners Group on mr2.com for a writeup on how to convert the Blacktop if you are interested, but the Redtop/Greytop are much better value for the work and cost involved.
