Thanks for the replies guys.

Thanks for the replies guys. EDIT: Can anyone comment as to how noticable the increase in drag is? Having a hard time finding full flares for the vehicle in question, most are similar to the ZG style flares for the Z.

Hey guys, Just a quick question, with the ZG style flares you end up with a fair amount of tire out of the body, does this have any noticable effects on drag and general aero? In any motorsport class other than open wheel they are always completely enclosed on the front and often left open at the rear to reduce pressure build up in the wheel well. Does anyone know if there are any noticable effects of having the tire sit out from the body? Regards, David

What are you planning to do for the front? Also can you either name the fenders or link to any pictures of them on a finished and painted car? I love that front to rear side shot, looks very mean.

Thanks for the replies guys. I did try a search but im not all that good finding something I can't remember where I saw that was just a stray picture. Thanks again.

Hey guys, I swear I got this picture from hybridz but I can't seem to find where or whos car this is. I'm quite interested in these flares, they seem to have a nice shape as well as being wider than the more common ZG flares around. Does anyone know whos it is / what flares these are / if there is a build thread? Thanks

Wow thanks a lot for the pic By girdle did you mean for the cylinders or for the bottom end because the bottom end is one of the best on any production engine, its a full solid cradle with 4 bolt mains. Definately new rods and pistons for that level of power. I have a bunch of pics from the nissan press release of the HR if you would like them - all quite high res. The standard crank looks pretty good to be honest so unless your going for a stroker crank in which case the VQ40 crank is rumored to fit though I don't think anyone has proved it. The VQ35HR VQ40 and VQ37's all use very very similar blocks and from what I can tell are all the same deck height etc with the main difference being the extra oil passage to run the VVEL on the VQ37VHR. Can't wait to see your engine build and thanks again for the dimensions.

Loving the build Hey Mark is there any chance you could measure the HR up for dimensions and post them? I can find dimensions for the DE but it seems the HR has a taller deck height according to the nissan press release I read on the engine so dimensions would be great if your able + help out anyone considering swapping one. Are you staying open deck or will you be using a brace or sleeves with brace like the honda boys? There seem to be several 500rwhp+ open deck 350z's running around so I wonder if its just down to putting it together right. Care to mention how much power you are after?

Sounding good mark. I'm glad to see you chose the HR as it seems to be a far better engine than the DE, I have a bunch of pull down pics of the HR and the bottom end is a very nice single cradle. It has a fair few similarities to the nissan VH range v8's to be honest and that is a beast of a bottom end for a stock car and the HR looks a little better imo. I wonder how good the stock internals are, I know it has different rods and pistons to the DE as well as a taller deck heigh which matches the VQ40 which was to allow for longer rods equalling a better rod to stroke ratio which would have been to make higher revs more reliable no doubt. I doubt the stock bottom end would like much boost as it seems they have done a fair bit to minimize rotating mass and improve NA performance but with aftermarket parts that thing should be a beast. Better redline at 8,000+ Gotta love old rules, definately one of the things drawing me to the 240 for modification. Its getting to the point over here you can't have a front mount without getting it engineered. The wheel looks quite nice, did someone get inspired by audi rims? They are quite a nice stock rim, on the rs4 etc. Got specs for the rims? Dare I ask how much they will cost haha? I imagine manufacturing wise a two peice would be much cheaper to build, any comments?

Hey mark, Any updates? hehe. I'm guessing this is going to be a track only car or are you going to get it road registered as well? Would you be willing to share info about the HR once you start the engine build? David

Is there an M104 tech website or something I can do a bit of reading. In regards to John I don't think this has been turned into what is the best engine as its more discussing bang for buck out of different engines but obviously varies country to country. MAG in regards to the RB25 box they are quite expensive here as well, easy enough to get a hold of but your still looking at $1500-2000 kind of money and considering you can easily get a T56 (double overdrive) for a few hundred used and will hold similar power not to mention being a six speed and having a far better top end gear ratio for highway cruising. I hate the fiddling around with making custom bell housings though as most nissan boxes have the bellhousing and trans casing in one so its pretty hard to get one to drill for another trans.

Mag58, my post wasnt to say just do an RB or JZ as much to just show that they are a well know and able engine. I really like to see people using other engines and what I would really like to see is someone put a 13B REW into a S30, that would be a crazy little car. RBs are definately a lot more attractive over here I must say but the prices can still be pretty crazy, who knows you might find the Merc engine to be better value for money overall or possibly a better engine with internals. One thing that would be interesting to know is the weight of the M104 series, the biggest down fall to me of the JZ and RBs are very heavy engines for the capacity.

I havent seen to much about the M104 but honestly the 2JZ and RB series are just as capable the main difference imo is the capacity of the M104, bigger capacity = more able bottom end torque and seeing as the Z is light enough I dont think this matters to most people. It is most definately interesting to see other engines and learn about them - just saying the 2J and RB are still more than able to rev to 9-10k or be tuned for low end torque. Cams tuning and turbo choice all affect power and torque delivery but most people seem to go for a nice smooth power and toque band right up to redline. Most of the RB26 30s down here using a GT3540 are making 700nm+ at around 320rwkw or about 430rwhp with peak torque relatively low and most of the graphs I have seen show over 450nm @ 3000rpm with most hitting peak torque between 4750 and 5500ish. Here is an example, I can pull up at least another 15 charts from different cars if people are interested or just check out the RB30 hybrid resuts thread on skylinesaustralia.com. Now i'm not hugely trusting of many dynos etc but every single dyno has shown 800nm+ out of these things so they can be pretty potent not to mention break pretty much everything behind the engine haha.

You can get them cheaper then that and they are very common being in the R31 skyline as well as a local manufacturer Holden's sedan of the day and later being offered in the Patrol, my step brother still has his old R31 sitting out back of his place, could probably get the engine for free as he is never going to finish it haha. The main issue with them is getting the right block, there seem to be 2 different types from my reading one which has oil in/out for the turbo and the other that doesn't so obviously the first is the one you want. Its only being in Australia or NZ that makes the RB26/30 a competative price option to the 2J as you can get the 3L bottom end for sub $300 + $1200ish for a 26 head and from there its rods pistons rings bolts crank collar pumps etc etc but really nothing more than you would be doing to build a regular RB26 but instead of forking out 4.5k+ just for the engine you have a build engine for that price or less.

Amazing build.
