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:

http://www.nengun.com/midori-seibi/titanium-gtr-front-pipe

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?

      We have a huge update coming in the next few months, version 5 of Invision will be released. I'm holding off any changes until after this change as I'm not sure what features will be removed or introduced.

      Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
