i beam is better for torsonal loads ie.. hitting boost. h beams can be made lighter.

it really depends on what your aiming for. then you got the whole wich brand argument lol.

from the look of it youd be safe to use some cheap china made h or i beams like eagle, scat and some of the sub 1000 a set i beams.

Sts rods may be good. But by the time you crack test them , shot peen them, resize them and get good rod bolts for them are they any cheaper then the entry level rods you can get? Even Argo are cheaper these days as their pricing seems to have responded to the cheaper rods available on the market

Thats provided the Eagle etc rods are in fact better then what Nissan put in the motor.

By the time you 'prep' the std rods you may as well spend a tinny little more and grab a set of forged rods.

All engine builders (that I have spoke to when building mine up) said not to waste the $$ on 'prepping' rods when these days after markets can be picked up for so cheap.

It really is saving minimal cash.

Go for the aftermarket rods. A set of Eagles or similar will only cost you $300 or so more than modifying the standard rods and you have something brand new that hasn't done millions of cycles already and is a better design and stronger than the factory rod to start with. They may need slight machining to set the proper pin and bearing clearances but it will be minor, most aftermarket rods are supplied with the pin and big end bore finished to bottom tolerance to allow adjustments to suit the crank/bearings and piston pin. Don't be scared off by the rods being made in China, a lot of big name companies have either set up over there or have their parts made by chinese factories, it reduces the cost to make the same product.

Just a quick point on testing standard rods.

Some one mentioned having them checked by x-ray rather than MPI (Magnetic Partical Inspection). To be honest its pointless having the x-ray done, its alot more expensive than MPI or DPI testing and unless correct technique is used it will not show up very very small cracks.

I would reconmend DPI (Dye Penatrive Inspection) Testing. This will show up any cracks or flaws and in my opinion is easier to do than MPI.

The rods are soaked in a dye for a few minutes and then cleaned off using water or a cleaner. A developer spray is then used, this will bring out any dye that remains in cracks or flaws and thus you can tell if the rods will be OK!

I was tempted to use standard rods but I think I will spend the extra cash and have new H Beam rods fitted, they are a good price now.

      I know mentally you're set on the ATS clutch but honestly I'm a big fan of the Nismo Super Coppermix Twin. It's much cheaper and in some ways I think it's a better design for a street/circuit car.

      Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.

      Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.

      It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!

      Nominally yes but I’m not really at that stage yet. Outsourcing to Japan is also a relatively good deal at the moment because their currency has devalued much more against the USD.  You would assume this but a lot has changed from the pandemic. Mechanics are in short supply and demand for fixing old cars has gone up from the cost of new cars. 250-300 USD/hr is not an unusual shop labor rate in California and you’re paying that regardless of whether the guy is competent or not. Coworkers have been quoted 3000 USD for a water pump and thermostat at a dealer on an N54. Oil changes went from ~75 USD to 150 on fairly normal cars like Civics. The cost of the oil and filter hasn’t even kept up with inflation.
