    RB25 Powered Sil80 Streeto Dori Project

    As a few people are already aware, I recently got a New Workshop.

    This is one of the first projects to be done in there.

    I'm building it for a mate, and hope some people may find it interesting.

    A few pictures of how the car looked when it arrived.











    And the Motor of choice, A Series II RB25DET out of an R33 Skyline, complete with Greddy Plenum.

    The Shell already had an attempt at a removable slam panel that we'll re-work later on.

    Put the Motor in for Mock Up and to check Clearance.

    Also mocked up the Radiator and Intercooler.

    Looking good!

    What sort of cash would I be looking at for an RB25 conversion for an S14A?

    depends on what you want in it...

    as in do you want the standard inlet manifold, oor do you want a GReddy style one??
    are you going to modify the subframe or use a skyline one??
    what power do you want from it?
    and are you doing it yourself or getting a garage to do it??

    i am also having the conversion done and i have spent quite a bit doing it..

    I'd get a garage to do it and I'd really only do what was recommended. If the skyline subframe is a better option that's what I'd choose to do. I'd not really want the Greddy IM but I'd use my turbo etc from my S14 just now probably!

    As it's destined to be a Drift Car, I'm going for Fiberglass Over-fenders Riveted on.

    The owner of the car has a set of 'Origin' +50mm's.

    Thanks Ross.

    As dannyboi200sx stated, It's pretty much dependent on what you want done.

    I would have thought a basic install with you supplying the parts would set you back around £1500'ish ?

    An RB25 on an S13 Subframe will need Custom Motor and Box Mounts.

    If you use the long RB25 Box you'll also need a Custom Prop-shaft I think.

    Other than that, it will be:

    Custom Wiring Loom.

    Possible Bulkhead Mods.

    Intake Plumbing.

    Radiator Plumbing.

    Custom Exhaust Elbow and Downpipe.

    I think that's the most of it.

    The Greddy Plenum's are a bit of a pain when it comes to clearance.

    The Wheels on this are quite interesting.

    Although essentially just a Work Meister S1, I believe they were custom made for one of the D1 Drivers in Japan, which explains the Dishy One Piece Rears.

    It did mean we needed to convert from 4 to 5 Stud, and lose the Conversion Spacers.



    R32 Skyline Rear Hubs.
    Fitted New Grippy Handbrake Shoes at the same time.



    Did the same with the Fronts.
    S14 Front Hubs with S14 4 Pot Callipers and S14 Lower Arms to increase the Track width.









    Thought this would be relatively straightforward, But thanks to the Rust, took most of the evening.

    You can't write something like tthat and not give the wheel specs

    I know, I wouldn't normally but I'm not sure on the Specs at the moment.

    I'll have a measure up today and work out the Offset.

    im not sure on the bulkhead mods but i know for ure you have to get a prop made up. it may be possible to use the r33 downpipe/elbow/all-in-one piece downpipe, radiator plumbing is just getting lengths of the silicone hose and making it yourself, and intercooler pipework using the standard inlet manifold is a right pain in the arse and you have to cut some of the bonnet brace off to make it fit.

    on a s14 you can use the r33 subframe and it fits, you have to make a gearbox mount, and the wiring loom you have to make yourself.
    if you think about parts you may need the list could be alot...

    The Modifying of the Bulkhead is mainly dependent on how far forward in the bay you decide to mount the Engine.

    I've got the RB25DET mounted to an RB20 Gearbox for this project.

    The RB20 Box is much shorter so you can retain the standard Prop-shaft.

    Upon fitting the S14 Lower Arms, It seemed a good idea to install new Ball joints.












    The ARB Drop Links also came out in pieces, So they were replaced with New Polyurethane items both Front and Rear.

    Decided to junk the boot lid in favour of an already repaired, straight and rust free one.





    We were supplied a really poor quality copy of a rocket bunny spoiler, And as I hate rocket bunny crap anyway, decided to make my own version of it.

    Started making the original one fit to use as a base.



















    Aiming for an Aggressive Nascar style deck spoiler with quite a sharp edged finish.

    I'll go to and from this while doing other things.
