The crank's going to be scrap so I've stripped a second bottom end and am using Clevite 0.25 undersize bearings all round, rods, mains and thrust washers. I just need a few hours to pull the engine and figure out what made them let go then I'll throw my 550cc injectors in and go tuning (Innovate wideband and SAFC)

Yeah I'm aiming for anything around 400bhp, more than that gets really difficult to put on the road with rwd and no traction control!
550s can be pushed harder but it's a safe area for them to be in with ~80% duty cycle and the pressure I'm running for fuel. "1jz's like a fast run in" Not sure what you mean by that? The 1J (2.5 twin turbo) is a different animal to the 7M (3.0 single turbo) and give a totally different feel to the car. I've done lightened, balanced and polished cranks but it yields very little noticeable gain. The latest one is auto but I've got an R154 to strap to it while the engine's out. Again, had an RPS flywheel (one of the finest) and didn't rate it as much of a gain. The Spec Stg 3 clutch however was brilliant! The problem with these cars is that they accelerate just as much at 140 as they do at 70!

![]() ![]() Oh I see, I thought you were asking about performance. Everyone has their own break in procedure, some go hell for leather from day one, some nurse them for thousands of miles. I go fro a 200 mile oil change and 500-1k miles of gradually working through the rev range then thrash it until it dies ![]() The 7M isn't a particularly revvy engine anyway (unlike the 1J), it's a torque monster so lightened cranks/flywheels don't (imho) work so well. Try fitting an atmospheric dupm valve on an AFM controlled car and you'll know all about stalling at lights ![]()

The problem with AFM as opposed to MAP is that you are releasing metered air so it will affect the car. How varies between cars, models and manufacturers but generally you'll run rich for a while. As standard it's always recirc (I don't know anyone who does a stock atmospheric), but dual piston types such as the Baileys DV26 work fine. HKS SSQBOV are also no trouble.
