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.

      R34 Skyline climate control unit transistor

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      I think Fitmit had some, have a look on there (theyre Australian as well)

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.

      Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
