Front Pipes To Match Hpi Dumps / Tomei Ti Exhaust

Hi guys

I am putting a set of HPI dumps onto my RB26 (76.3mm outlet from memory) and have a Tomei Ti exhaust (90mm) from the cat back.

I'm trying to find a suitable set of front pipes that will match those sizes, and the only ones I can find are:

Pentroof:

http://www.nengun.com/pentroof/large-diameter-front-pipe

Midori:

The thing is, I would prefer tuned length if at all possible - are these tuned length?

If not, is there anything else that would be suitable that is tuned length and matches my 76.3mm dumps and 90mm exhaust?

Cheers!

as scotty said it's not a manifold so just plumb it up as it fits. You're best bet is going custom but you might get lucky with an off the shelf part

I had the same setup, ended up getting some custom twin 76mm to 90mm front pipes as I couldn't find any off the shelf that size

Cheers Michael, have decided against the two I posted and will look for a custom job as well

Scott and Tim, sorry I'm lost on what you're talking about - I think you've misread my question - I'm not looking for advice on tuned-length vs non-tuned length pipes; thanks for the input anyway.

Well then you should pay $1500 to $2000 for those "Tuned length' pipes shipped from Japan and not ask our opinion. It's not like I know what I am talking about anyway...

I could make better pipes than those for under $500 in stainless, and they wouldn't drag on every speed hump you drive over.

So it's tuned length vs tuned design!

I missed the bit where the OP asked for opinions. I assume he wants tuned length because they sound so much nicer than non-tuned front pipes.

Do you have any examples of your front pipes out of interest Scotty? I could only see these pieces of art in this build thread. The turbo elbow particularly caught my attention.

I don't, mainly as I have never been asked to make them. Typically most GTR owners want 'brand name' parts I have found.

I assume Tony's outlet pipe looked a little 'wrong' to you, it was the only way a turbo that large would fit behind the PS pump without hitting the strut tower. A close up of the exterior of the pipe is interesting, but the inside was perfectly smooth, and it flowed the numbers... Again, not something a GTR owner would generally go for, it's not shiny enough, no matter how practical it is.

Most of the jap stuff is junk. Exhausts, catch cans, most fuel rails are junk designs. Aussie engineering could take it to the jap "bling" companies without batting an eyelid. Catalogue shopping is junk.

I think you need to ask the japs what they thought of our Aussie Godzillas before making that remark.

Maybe ask them what they had been taught from us......

Am I?

You bumped a 12 month old thread to tell me I'm an idiot! :/

The point I was trying to make is that you can't just flick through a trust/Nismo/HKS/whatever and pick parts and expect some awesome result.

An example. A SARD fuel rail. Looks pretty, duel entry single out. Sounds sweet yeah? The bloody piece of shit doesn't have a seat for the injectors to push up against. Waste of time.

Kakimoto Full Mega N1 exhaust. Looks mad with it's bit tough cannon. Has some 2 inch restrictor/"silencer"/taper down/whatever you want to call it in the rear muffler. You're so called "90 mm exhaust" now because a 50. Waste of farken time.

Tomei Expreme RB 26 stainless manifolds. Cost a fortune, look pretty. Made from shit stainless that crack and also offer no performance advantage. I've personally done a back to back. A mate has a Evo Tomei manifold sitting on his garage floor because they're cracked. Make a good paperweight though!

Two quick examples that quickly came to my head.

Have fun with your catalogues, mate!

His name says it all Piggy don't worry son! :)

Your cars results speak for themselves and i think the only Jap parts you have on it are the cooler and intake manifold?

      I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.

      S1 rb25/s14 starting problem

      By GTSBoy · Posted

      Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
