Hey guy's what's up? I'm just going fishing here but Why not see what other 2.5 liter guy's are using for turbos. I know the 93-97 Probe GT's have a single and twin turbo kits and they have a Mazda 2.5 liter engine. Just thought it might help. I'll find out some info on the Probe board. I know a guy that posted on this forum who owns a single turbo probe named bigprobe on the board. Maybe we could ask him. Just trying to add to the excitment for a turbo for our SVT's.
