Looking to replace the crank pulley on rb25det, thoughts on options?

New stock pulley with nz wiring CAS

ATI with nz wiring CAS

Ross pulley with trigger kit

ATI with PRP trigger kit, getting a bit pricey for my specs.

Car is currently around 350kw but future proofing for 4xx kw.

You sort of have to choose which ecosystem you might want to be in and then that can inform the choice between Ross and ATI.

A rebuildable balancer is always a good thing to have.

Personally I'd stick with ATI.. either 750 or 1000hp version, and stick a trigger kit too while youre at it. Lots of choices for trigger kits.. dont have to get PRP if you dont want to. Either way, wont get much change from 2knz. In saying that, the NZ Wiring CAS is an excellent upgrade too from stock.. lots of guys run them. Depends how much you want to fork out really and how hard youll be pushing your setup.

We must be related.

I use a NZ Cam trigger kit with an ATI balancer. I needed to get a custom PS pulley to suit the RB25 PS pump from Hi Octane Racing.

Motor hasn't exploded yet, makes 437kW, has seen half a dozen track days at SMSP, 2x silly wannabe Power cruise events and runs AC.

Do you reckon the ATI is better than the Ross? No one seems to have an ATI for a 25 in NZ at the moment.

What was up with the PS pulley?

Goes from a cam belt, service, into a 4k job, typical lol.

Seems slightly more economical to do the Ross if doing the trigger, although can't seem to find an ATI in NZ at the moment.

I personally don't like Ross, and especially after they sold me a PS idler kit that was poorly designed and doesn't work with the RB25 out of the box.

Another person has the same issue too.

I emailed them numerous times, sent them photos, videos, etc. and they've ghosted me the pricks.

36-2 balancer is the biz. Personally prefer it over a gear with teeth. 

I run an ATI 36-2 custom wheel on my street car as it has Aircon 

Putting a ross 36-2 on my race car, no AC. 

 

I'll look up the company that did the ATI if your interested, sit down price though :)

Car doesn't have AC, it's already turning into an expensive service lol

Is it the ATI for a 26? Ghosting with issues isn't good

FWIW I run an ATI R33 RB26 balancer on my car, however with this RB25 PS pulley from Hi Octane Racing.

https://www.hioctanedirect.com/Hi-Octane-Racing-R33-GTST-ATI-Power-Steering-Pulley-SUIT-750-HP-Balancer

 

Says it works with the 750hp balancer, can only find the 1000hp version here? I'm more lost now lol

 

@Butters Are you using the full Ross trigger kit?

Yes Rb26

I am using an Ignite 5.0 bottom/crank trigger on the ATI and will be doing the same on the ROSS.

On one setup I have VCAM so using that sensor as the top/cam trigger. *cough Toyota style ... *cough

On the other I am using an Ignite 5.0 cam trigger.

 

I also use link ecu too, so once you get sync, the ecu runs completely off the crank. You can literally unplug the cam sensor once started.  I get zero trigger issues and drive the car weekly.

    • Go to SP mufflers and get the muffler of size you want and make a nice mid muffler. It's about that simple! I have 2x 3.5 Magnaflow straight through Mufflers and while it's pretty loud with the Varex open, it's quiet enough with the Varex closed. You can also buy off the shelf Magnaflow straight through mufflers as well. You also have a turbo to quiet the car down too. Don't overthink it. Buy my extra Magnaflow muffler sitting on a shelf doing nothing (buy it new, ignore this part)
    • Centre-offset muffler under the floor, same as stock. Just....3.5". The change from straight pipe there to centre-offset will mean that you need to remake some of the pipe (add a bend or two).
    • Hey guys. So my R34 GTT has a custom 3.5” exhaust (done by previous owner) with a high flowing cat, and then just a Varex cannon muffler on the back. The car does drone alot and is really loud even on highway driving just cruising, as you can imagine due to the Varex muffler basically being a straight through with the valve open. As much as i love a loud RB, it can be a bit much with no other muffling in line and just driving casually. I wanted to lower the volume output on the exhaust a bit, as well as remove the drone (probably a way to do both at once), and was going to do it all myself as I am a fabricator and have done exhaust work in the past, so the fab work isnt my issue, im just not sure on the right product or type of product to use to get the job done, and i doubt an exhaust shop would be wanting to help me as they wont be making any money from helping me, unless they supplied the product? Anyway any help or guidance in best way to approach this would be awesome   Thanks in advance
    • Meh, whilst the Honda is a "really" good car and has potential if you want to drop coin on, it was uninspiring for me to look at, but, it did serve its purpose and is now in the boys hands, his happy, his girl is happy, as she wasn't to keen on the noisy old Patrol, and most importantly, the Minister for War and Finances is extremely happy that her "little baby boy" (6'2 nugget who is currently training to be a copper, which will make 3 coppers in the immediate "circle of trust") has a well sorted reliable car that doesn't guzzle diesel Me, I'm more than happy with the NC MX5 that I replaced it with, it's a fun little car that I like looking at, like driving, and yes..... I do like the fact that the maintenance and modifications that I have done/will do are plentiful and relatively cheap, well........ while staying naturally aspirated slow that is, and that's all I really need for a fun little daily, I can rev the 5hit out of it rowing through the gears and never really break the speed limit  In saying that wicked word, "modifications", I've already ordered something for some noise and an additional "3 ish" horse powers, or whatever it gives, in the form of a header, and, a new set of "cheapo" BC coilovers that are already sitting in the shed waiting to get put in, I had the same BC's in my old NB and found they were fine for the street, hwy, and the occasional track days I did in it, they have 6kg front and 4kg rear springs which is about 10% stiffer than the stock springs which I found worked well for their price  I've also already been in touch with MX5 Mania in Dural, so once the header is on it will get a ECUTek RaceROM tune there (I cannot rev match for 5hit, and I loved the RaceROM rev match and FFS in my old 86 "RIP") In other, maintenance news, I put some new sparkler plugs in it, and have a new set of DBA Street series pads to put in over the next day or so, I'm running the DBA street series in the SS and Honda and really like them, they work great and are not dusty at all I've also booked in a few days leave over this weekend to give me 4 days weekend do some paint correction and give the leather seats some conditioning and interior some Bissell and steam cleaning OCD lovin', the carpet and interior looks clean, but from my experience with the Bissell IRT carpet, and the steam cleaner IRT trim, looks can be deceiving I've also found that finding a detachable hard top is proving problematic, the main reason why I didn't like the NC initially was the power retractable hard top that I seen them with gave the roof line a weird look, the detachable roof though looks good, and is a same shape as a NA/NB hard top, similar, but unfortunately not the same as it has different fixture point on the front, so fitting a easy to get NA/NB detachable hard top is no bueno New Old cars are fun, cleaning, hunting and playing around brings much joy How are your beasties going? Do you still have the Skyline with the LS???, or Barra??? that you were playing with
