Went down and had a chat with him yesterday, nice guy. Will be getting a full custom hard pipe intakes setup done next week! Exhaust, im still figuring out what path to go down. Some are saying the varex's hang too low because of the valve it has at the top

The Varex is good if you want the ability to quieten down a really loud exhaust, and a fairly simple install if you have the clearance 

In saying this, a well designed exhaust, that doesn't drone, and "close" to not being a "big heat signature" for the constabulary, is a better way to go

Noise does not = power, but a well designed exhaust that isn't "overly" loud will not negatively effect power, it will though keep the constabulary off your back

I had a Varex, and it worked well, super quiet when closed, but sounded like war when open and up it, I did have available "realestate" clearance issues under the old SS though running a 4" exhaust, and the Varex was the best option for me, as the space where the rear box went was available for the valve, so compromises were made to quieten it down

I have seen, and heard, alot of nice RB's with just some resonators and/or muffler/s, which, while sounding "beefy" were not obnoxious cruising around, and not something that draws unwanted attention, but, they did get real rowdy when up it

The trick is to get an exhaust fabricated that doesn't break your brain, or your passengers willingness to be in the car, on a Hwy cruise, i.e. no drone, and also not have your neighbours breaking your balls because their house vibrates and wakes their family when you roll in late at night, or when you head out early in morning, but it also sounds real good to the ear

Post up when your done, whilst I no longer own a RB, I do love their sound with a nice exhaust, especially when there's a lumpy cam lopping away

Nice, glad Jesse will be able to look after you. 

As for exhaust, a couple of good quality mufflers should do the trick without the need for the varex.

Have a look at JS Performance Garage, just did a bit of work on a 32 GTR.

Thanks for bringing this workshop to my attention, i didnt know about it before and Jessie did some Fabolous work on my car! Helps that its close to home as well, hate having to drive half way across melbourne for a decent workshop.

Car looks clean as. You ended up getting quite a bit done 😂 

So what's the plan for the exhaust?

Yeh... literally every time i jump on a forum, see an instagram post or see an engine bay at a car show, i get an idea and add it to my 'to do' list. So what started off as, hey can u just make a couple of intake hard pipes because my dumbass bought the wrong apexi kit, blew out into a 2 week job including braided brake lines & custom bash kit for the front lip haha. 

Getting Luke from A4E engineering to make a full custom exhaust with a controllable aes dump valve so i can actually switch between quiet and loud, because right now its just loud all day every day. Then after that go and get the tune redone flex e85 & 98 as i get bugger all milage from e85, makes going for longer drivers difficult

Curious to why you're not getting Jesse to do the exhaust, seeing that he has just done 2 GTRs with Aes valves.

I only found out about Jesse's shop after meeting with A4E and having a good chat about what direction to go in with the car and exhaust setup. I didnt want to go back on my word as thats a bit of a shitty move, especially since Luke took the time to meet with me and have a really good chat. Theres not many places that do that anymore, most of the larger commercial workshops churn through the process like a production line, quantity over quality etc.

What's the time frame you reckon? 

Exhaust end of this month, and then tune after that whenever there is availability. Still tossing up between a pure 98 tune or a flex 98/e85 combo. 

The (lack of) milage in e85 isnt great. Start to get anxiety if i go for a long drive and there arent any united servo's nearby

But if you've got the flex sensor whats the issue? You just run what you can get your hands on. 

I can't see any reason not to run e85 if it's relatively local to where you live.

Had a good chat with Ben from Danellos tonight about which direction to go with the tune, we'll do a flex setup initially, ill see what my thoughts are on 98 and then take it from there. I mainly one want or the other, i dont want to be mixing both e85 and 98 for a weird hybrid fuel combo.

This is very confusing. "flex setup" = being able to run 98, e85 or any % of ethanol. 

If your tune only supports 98, that is not a "flex setup". 

I don't understand your hesitancy for running ethanol. It's just better. It makes more power and is safer. What's not to love? Also it smell amazing lol.

Currently on an e85 only tune, but I barely get 200km from a full tank. Makes going for longer drives difficult, especially when u leave Melbourne metro as there aren’t many united servos, hence why I’m thinking of going more of a 98 setup. 
 

And yes the smell lol. Any drive afterwards I need to have a shower and wash all the clothes I was wearing, it’s like someone made a Calvin clown e85 perfume and sprayed it all over me haha

The suspense is killing me lol. 

Are you going to buy a flex sensor, then add the 98 tune to your current tune? 

It sounds like your just going to delete the current tune and re-tune the car on 98 =/

If you've only known your car on e85, I don't think it will be long before you install the flex sensor and go back to running e85 when its available lol.

Ah, should have been clearer. Currently has a flex sensor installed all good to go. 
 

like u mentioned, I’ve only ever known the car on e85, I might hate 98, but I have to try it out first. Everyone says the -5 turbos get pretty laggy on 98 octane tho…

Nice, let me know how you find the 98 tune

The availability of e85 won't matter with a flex tune. Can mix and match and never have range anxiety again. Only thing will change is your ethanol %.

This.

I'm confused by the whole discussion.

The only reason you would have a car with e85 only if it was track use and you only ever used e85. All other use cases you add a flex fuel sensor, do the flex tune (you only need to do a couple of % and then interpolate the rest) and then you put whatever the hell you feel like including a mix in the tank and it just works.

Want a long drive? fill with 98

Want max zoom? fill with e85

Got a half tank of 98 then find e85 somewhere? Throw it in.

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
