    damn great progress.. so you arent sure what the block is capable of handling?


    why not just get an aftermarket crank if youre putting all this time and money into the engine? why risk it

    Well I could get a billet crank and Nissan N1 block that I know would hold but those are RB26 components so it would no longer be an RB25 which I'd like to do just because I think the 25 can do it. If it breaks I'm prepared to get all aftermarket components. The truth is at the power and rpms I'm gonna be putting through this motor I'll have to be refreshing it relatively often. In talking with people who are running the same class I want to they are getting about 50-75 passes before they go into the motor. And that's with atleast 2-3x my displacement at the same power levels. The RB25 will win me at least one X275 event I hope before I have to make a change.

    But to answer your question more completely, the 25 block and crank are very similar to the 26(no obvious disadvantages) and the stock 26 ones have been taken to this power before so I have a pretty good feeling the 25 will be okay.

I'm running Bosch 2225cc injectors. Yes I'm pushing the limits of the stock crank and block.
    Why bother with a stock crank at this point?

    I know it seems pretty crazy to keep the stock crank at this point and trust me its not me being cheap as a billet crank could be had for a decent price for the RB26 but the RB cranks are pretty well built. A few companies in australia and new zealand are spinning the stock cranks to 11,500RPM's @1,000awhp. The main issue with that is the vibration has caused a few rb26 blocks to crack but that's because they are awd and have the front diff built into the block so it torques the hell out of the block, not so with the RB25.

    Bob@NRC sent me a few quick pictures today of the beginning of my cage. Today they will cut the wheel wells to see how wide a tire I can fit back there and still remain within the class rules and also so he'll know what size housing to make for the rear end.

    Went and picked up a few parts and tried to clean up my garage from stripping the car which was a mad rush and left my garage looking like pull-a-part!

    Got the Compressor Housing Polished:

    Got the Full-Race Manifold ceramic coated:

    And got a set of Hoosier 28X10.5 Slicks:

    Making a list of all the electrical components on the car and how much they draw so I can begin ordering everything I'll need to make the new engine and chassis harness.

    Why is seeing some Hoosier slicks and a huge turbo so awesome?

    Its not the tires or turbo that does it for me its the chassis pictures. Seeing that its progressing has me anxious as $#@! to get all this done. Whats killing me is that the engine would be done already if not for me deciding to change the cams and needing custom made lifters. Supertech says they should be done by the end of the month and in my hands first week of september. I'm thinking about having it tuned on an engine dyno vs a chassis one so that I can try and get the converter dialed in on the first try and also to determine what the best gear ratio will be. I feel so damn close that it's pissing me off that I booked a vacation to the UAE during the biggest race of the year for my class. A couple months ago I figured it wouldn't be ready till next spring so I booked it for my wifes Bday but now I regret that. I wouldn't run officially but I would have like to make a few unpublished passes at the same time and track conditions my competition will be running so I can see where I'm at.

    After dealing with a real unprofessional guy who was going to originally make my dry sump pan I decided to go with real professionals that I knew where gonna get the job done. Here's a few pictures of my custom Moroso dry sump pan:

    I'm driving tomorrow to Charlotte for a few days and will take a slight detour to NRC for a quick peek at my car and to drop off a blown block that he will use to make my custom crossmember and trans tunnel. I'll post more pictures tomorrow if there's anything new.
