Making the R33 Jizzmatronic

[AndySkidmore]

So yeah I ended up with this pretty decent R33. after swapping it for my BMW. Had it nearly a year now and naturally I am bored shitless so I want to waste time and money;


Here's the list of mods when I got it, since then the only mods I've done are bulk skids

Modifications are:

-Genuine Garrett 3071 Turbo with braided lines and aluminium intake pipe.
-Vi-Pec Engine Management System, tuned by ESP in Queanbeyan
-Front-mount Intercooler
-Upgraded 040 fuel pump
-Upgraded 700cc (approx) injectors
-Split-fire coil packs
-Heavy duty clutch
-Full X-Force exhaust system
-Biggest pod filter you have ever seenn
-Re-shimmed and serviced LSD Diff
-Whiteline swaybars front and rear with new knuckles
-DBA slotted brake rotors, braided lines and Project-Mu Pads

Tuned to 273 rwkw - I think 400 rwkw sounds more appropriate. 

Some options I have though about;
1- put rb26 running gear in it make it 4wd and boost it some more
2- punish the Rb25 so hard it pops, then repeat that several times at maximum power
3- be cool and put a LS1 in it and twin turbo that
4- sell it and get a GTR (- I'd like one but I need the 4 door now plus the wife think its cool and my son likes it too).

Nice car. Needs moar booooost and E85 before you decide to spend insane $. May as well see how far you can push it.

I agree,  what will an RB typically tolerate?

What this setup good for?

If I add cams where will that get me?  - Keen to increase area under the curve as well as top end.

A stock unopened 25 will take 350rwkw without too much fuss. Head studs are probably a good idea. My own setup went from 260 to 312 from 98 to e85. I would think yours should make around the 320 mark. Cams typically won't be required but will give top end gains.

I'd get the GTX 3076, the 3071 is probably not gunna make much more power than what you already have. And just get the maximum sized injectors [do it once].  There is a thread here somewhere telling everyone that they idle and work just fine these days.  And the cost is about the same, so why not. but Glenn knows his stuff so talk to him about it.

Jizzmatronic you say...... easy.

35/40 or equivalent, supporting mods, block off your BOV,  tune, and you will have a 350kw dosing machine........ Jizz everywhere

If you must buy a new car get an autech 33gtr, awd 4 door using the gtr gear. Way easier than doing a conversion yourself

Unpopular answer:

What you have is actually the best/most fun setup long term. Anything more than what you have the "fun" to "BS/Cost" ratio goes massively, massively down.

Yep get bigger more modern injectors and a bigger more modern turbo and if your intercooler and exhaust system (3.5 in) are up to it you should have heaps of power. If the engine lets go (no reason why it should) put an RB30 block under your head for heaps of street friendly torque. If you want four door four wheel drive get a GTS4 and repower it.

Get GTX3576 with a divided rear housing, and a proper twin scroll manifold.. put in some headstuds and screw about 2 bar into it.. should see close to 400kw+ on E85

Your injectors are too small too and you need a new fuel pump.

[admS15]

There you go. You have from jizzmomild to jizzmowild. If that's not enough, ls1tt or lsa conversion will def be jizzmotronic.

Thanks Lads. Good inputs. Seems the obvious path forward is to setup on E85 and leave majority of hardware as is and I'm pretty sure the vipec can handle a flex sensor. Then max it all out and decide from there.

Might even give tuning it myself a red hot crack. A lumpy idle would be level 7 jizmatronic 

boost in the snow this morning was beyond luscious. Wheel spin through 3rd and hectic popping of the limiter.
