if a twin plate clutch drives nicely I'd be all for it so I'll have a look at those.

Well i'll agree with UWISSH that Nismo twins are well known for being pretty much as easy as stock clutches - but they're not cheap (around $2K?), and being a twin, they'll probably rattle. My point is, if you dont need to support big horsepower or brutal use, you could go with something cheaper.

NISMO twin plate. Forget singles.

I had a NISMO single, that was ok but the twin was MILES in front. Plus you can launch it so hard. On the shift change it's so positive yet not at all heavy like a twin

That was 262rwkw with both clutches.

Also, no rattle.

Thats my end of year wish!

I bought some R34 BB turbos thinking that's all I wanted but now been offered a set of new -5's for a great price.

Unsure if all the effort and cost of fitting the R34 turbos will be worth it.

Should I just go the -5's and only up the boost until the limit of the AFM's/Injectors and see how that goes?

Would that be a nice driveable package if I decided not to go any further?

I have a Series III R33 GTR with just an exhaust and PFC with boost controller fitted.

What would be a good next step to increase power and more importantly response?

Car currently has 292 rwhp

I smashed my clutch foot years ago in a MC accident so I really don't want to have to put in a heavy clutch and spoil the experience.

It's been suggested to upgrade the turbos to R34 ball bearing units and maybe Tomei pon b cams.

I was considering -5 turbos but that would mean injectors and new AFMs as well and may end up needing the dreaded heavy clutch.

This car will do the odd motorsport event but manly be babied on the street where I really enjoy the driveability

Any advice welcome

Advice:

Don't bother with cams, have a think about cam gears however.

A smaller version of the 2860 turbo would suit - either a -7 or a -9. Personally I prefer the -9's but each to their own.

A twin plate clutch with a lightened flywheel is a good idea.

Also check the Nismo AFM's as they will work at higher air flows than stock without the mucking about that the Z32's entail.

If you decided not to go any further it would be a poor package imo. You bolt on large turbos -5 turbos and then limit them to 280rwkw, so you get more lag and the same top end so no advantage.

I would only get the -5s if you plan to change the AFM and injectors one day. Until then it will be far less than perfect.

-9s are what your after, they would be good with the stock AFM and injectors but will also reap big rewards if you do change them.

If you dont have plans to change the AFM and injectors, and dont care about the reliability of ceramic wheels (from the fact you want to buy R34 BB turbos) then just get some cam gears, catback exhaust and a tune. You should get ~250rwkw out of that and leave it.

I can get the -5's for $2000 the pair.

Not sure if I would go any further but you never know what will happen if the power bug bites (again)

Currently I have dump pipes back exhaust and PFC tuned to 13psi.

I'm getting 296hp to the wheels and the tuner said with the R34 BB Ceramic turbos and the new dump pipes I'd get only say 330hp which doesn't seem worth the effort now.

Just confused myself :blush:

BAHAHA to going to the drags an NOT doin an 8000rpm clutch drop, done proabably bout a dozen of them at willow bank an neva had clutch problems with 275 tyres, i've neva changed the clutch myself but got a felling it may havebeen changed before it was imported.

    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
