R33 S2 RB25DET FFP Install - HELP

Hi all,

First poster here :)

I've got a few questions about installing a FFP. I've got a stock R33 S2 with the usual (FMIC, BOV, POD, Coilovers) around 176,000kms on the engine. The engine itself is very healthy, running stock boost but pulls like a dream, always serviced every 5,000kms with Penrite 10W40 Racing 10, spark plugs etc by myself of course.

 

Now, I bought a FFP the other week, pretty sure its a Greddy remake, got it for a cheap price with all the fittings, screws and throttle body. Also bought the stock Inlet Manifold Gasket from Autopro just incase the one on is no good.

Basically I want to tidy up the engine bay a little as I hate the look of the stock plenums and the J-pipe crossing over the engine is a pain to take off every time to do spark plugs. I'm very mechanically minded, been around RBs for years, done a few things to them and done a few engine rebuilds etc.

So my questions are; anyone here done a FFP install themselves? How long did it take and what difficulties did you run into? Anything major to drill/reshape etc or just bolt on stuff? Where does the BOV get relocated to as the crossover J-pipe gets removed? Where do all the vacuum lines go?

If anyone can get back to me ASAP with answers or even videos that would be more than appreciated as I don't want to start something and end up not being able to drive my baby, looking at doing all this over the weekend, cheers guys! :cool:

NOTE: PICTURES WILL BE UPLOADED (ENGINE BAY, FFP, THROTTLE BODY)

There's a big how to thread in here somewhere. If you can't find it through the search function just Google. Get an adapter so you can use your stock throttle body. As you have bought it already I guess its a bit late to suggest putting the money towards a bigger turbo instead...

I've tried searching but nothing came up, also found one a few days ago through a Google search but it was pretty messy, how the guy did it etc..any pros to using the stock throttle body?

What turbo do you suggest? I want something capable of 350 - 400hp for street use with no huge lag!

The pipe from the intercooler to the throttle body will need to be remade. The bov gets installed before the throttle body on the new piece of intercooler piping and new pipe work will need to be made from the bov to the intake pipe, or don't bother reinstalling it and enjoy the flutters. The lines that are on the J pipe get installed on the new intercooler pipe and the lines that are on the stock plenum get installed on the freddy plenum, the factory lines probably aren't long enough so you will need new longer pieces of hose.

Get a GTX3071 with the divided rear housing, then get 2x external gates on and sit the lot on a 6Boost twin scroll manifold.

Screamers out of the bonnet or side quarter for extra street cred :)

the standard intake manifold will make the power goal you need,  so will the standard exhaust manifold.

 

Just get a bolt on turbo like what I have for sale atm,  install injectors and fuel pump and fmic.

FFP is not going gain you any power.

      WGNC34 - floor mats

      By soviet_merlin · Posted

      I'd be very surprised if you can buy new OEM mats. But if you can, I want some too!  Do you have links to the variations you found? Also, where are you located? I found that Nengun is happy to list items to purchase but when you do buy them you'll get an email that it's actually discontinued. As far as I know the variations in floor mats are different colour schemes as well as automatic and manual having a slightly different shape. The automatic ones fit into a manual car without issues, but I think you'd have trouble fitting the other way around. I have photos that show the shape difference if you care. FWIW I bought sets of used floor mats in decent condition at yahoo auctions.

      WGNC34 - floor mats

      By Marek · Posted

      Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though

      Ethanol Content Sensor - Always at 11%?

      and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.
