How about we wait for some real world MPG numbers to come in before we start talking all kinds of s***. I would like to challenge someone to install any of the aforementioned diesel engines into an 80 series without completely bastardizing the job, lets see how far you can get. And to be clear, you can only preform 2 metal modifications to the vehicle, one to install the clutch master and the second to modify the trans tunnel to accept the h151.
Back on point. Things have been delayed due to toyotapartsdeal.com, I am waiting on some OEM clips for the trans harness. I want to get that installed correctly before I put the h151 back in. Trust me, its not very fun to do by yourself.
There has been some debate over the fuel filter setup since cummins own documentation says that the filter head needs to be vertically located between the tank and the injection pump. Without resulting to hackery this is simply not possible on this platform. Looking at Proffitts builds they located the fuel filter in the only place that makes sense, this would be close to where the 1FZ evap canister was located. The height of the fuel filter does not help, its a monster. Also the plunger sticks out parallel to the floor instead of at a 45 degree angle like the recor units do. I am convinced that Cummins let the interns design the filter head, why not just use an off the shelf recor unit?
I decided to stick with the OEM filter assembly for know, if it needs to be changed later it can be. The assembly must be mounted on the inboard side for clearance, I designed a little bracket to help with this. It uses the evap bracket which is a nice piece of toyota engineering, it is held in by 4 bolts I believe and is quite stiff.
The extra large slotted holes accept both the cummins filter and the 400 series recor, always thinking ahead. The thickness is essential because you need to be able to plug in the water in fuel sensor into the bottom of the filter. I have tried to check for hood clearance the best I could by projecting lines across the top lip of the front fenders, I think we will have about 1/2 inch.
Next up is the oil filter. Some may have noticed that the R2.8 gets a different front cover assembly than the regular ISF2.8 engine. At the beginning I was excited about the remote mount filter, now I am not so thrilled. The ISF design would be perfect in the 80 series, this remote setup will be a bitch to install correctly. Cummins says filter lines need to be less than or equal to 0.5m in length, that is kinda limiting. The LHS is completely full with the clutch, starter, fuel filter and steering box, so the only place to go is to the RHS chassis rail.
There are holes in the chassis where a RHD steering box would go, I decided to use 3 of them since the 4th one is cover by the stiffener bracket for the LHD steering box. With the filter in this position you just take off the front splash shield and the filter is right there, should be able to drain straight down into your catch pan without running all over your chassis and axle, the drawback is that I will need to make some custom oil lines to connect the engine and filter assembly. This bracket uses some countersunk bolts to attach to the filer head and tucks right up against the chassis rail.
