I think a 6870 could be a good match for a 2.8 with vcam and you'd probably be all in under 5. Keen to see someone try it though.

Nothing wrong wit a 6466, its a perfect street turbo imo just doesn't have the legs of the bigger cars.

doesnt one of the dahtone cars have setup? 2.8 + vcam + something

The 6262 sillyness is never ending... New cams just got the most power and torque it's ever made

Dale is 100% correct its a well proven fact that smaller cams in RB's aid in response. Even going from a stock cam to a type b pon cam will cost you response. Been many track guys that have thrown the

I was talking to the owner of the r32 gtr with the plates “billet” he has a 2.8 in a billet block making 1150hp at the wheels and regularly drives it on the street and has done 40 plus passes (best being a 9.0 at 160+mph) and he says it’s never been an issue and he drives it in stop/start traffic and the lot.
 

What he did say is he changes his oil pretty regularly and makes sure the oil is up to 80° before he drives it and apart from that it’s no different to having a cast block 

Yep the Malas brothers have had a good run with theirs and it does get driven.

They have also changed the oil as regularly as every 100km's in it and are pedantic about oil and water being up to temp before any kind of revs (which is a good thing) which I am sure does help.

That being said I have no intention of ever putting one in a street car :)

Maybe a minimum oil change interval specification is required for a car to be called a "street car"

Not exactly feasible to warm up the car for 10 min in order to pop around to the shops or the gym

I used to take mine to the gym all the time, then out for a coffee at the local shops.

Will definitely be doing it again when it's back on the road

Not just sitting there idling though, quicker you get to operation temp the better under light load. It'll take a lot more than 10 minutes idling to get to 80 oil temp, even at 40+ ambient unless your cooling system sucks.

Mine comes out of the garage and runs till i know the door is down then its off down the road. Maybe 3 minutes and i am out of there. The engine is 17 years old now and still going strong. We have a GReddy sandwich plate with thermostat so it gets temp into it quick, but i cant be bothered warming it up. Just drive it sensibly and it will be fine

This.

 

Can't stand it when people sit there idling their cars for 10+ minutes, it's doing more harm than good. Never seen a GT3/V8 Supercar/Pro time attack car etc sit idling for 10 minutes, you fire it up and get moving.

yup 100 percent mate. i live in an area where it gets extremely cold even minus 50 celcius sometimes. even then if the block heater was plugged in you only wait a couple minutes(or high idle it and thats better) then slowly warm it up driving keeping rpms lowish. warms everything else up slowly too transmission diff etc.  im sure most of you mates see how long it takes oil temps to rise in a gtr so just imagine your rb sitting there tryng to reach oil temps at idle? would take for ever and does a number on your rings especially older motors that arent perfect anymore. my gtr always smoked out the exhaust a bit until i got her warmed up so i never let it idle longer than 1 minute(and this wasnt the turbo as was a brand new precision).  get the rings and pistons hot soon as possible your engine will thank you.  that sitting idling crap is for the birds.

You tune with JEM right ? What did they say ?

Back onto the topic of billet turbos instead of billet blocks

i was at a dyno day at jem early this month and decided to ask Adam about the 6870 2.8 combo while I was there, he said it should make 650kw at the wheels and be all in at 4500

I think he's dreaming....

Have a look another look at Reapers graph that you posted? 

A large static cam 2.8 will do better than a 3.2L V cam? 🤔

      Quieter performance exhausts (or muffler add-on options)

      Nope.    Grab a varex and turn it down as you get close to home, win win?

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      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
