Engine Build Thread

[elperuano]

I like the idea of a striker kit also. Haven't seen one on the 37 yet, maybe 1 car that had numerous sponsors. White 370 I think had stroker.

[Nissan370]

just to recap for my build not to include the lame stillen kit i am using

wiseco 96mm 15.5cc forged piston (just under 9:1cr because of a thicker head gasket)

eagle rods with bearings(using the stock bearings new)

arp headstuds

fuel were using automotive 340lph fuel pump w/upgraded wiring and 900cc injectors
may not need to go return just yet

so for right now fuel and a shade motor is not a problem i just need to get the correct power adder to really love driving this thing

I believe that the blue and orange 370 for sale in the classifieds with the Stillen SC kit has a stroker motor. I however don't think he has any information on gains.

No stroker for my build, although it is tempting. IIRC, just more heat. I'm sure responsive tuning is more than adequate.

I think there have been a few GTM customer vehicles with the stroker motors as well. I am mostly interested in how that would affect torque and turbo spool. I am guessing I might need to upgrade the GT28s to something larger to really utilize the increased displacement. Any thoughts?

DIGItonium - I think you could manage heat well with an upgraded radiator, which for reliability reasons, I would probably want to do if building the motor.

[elperuano]

Might have to upgrade turbos or push more boost to reach desired hp level but you can only turn it up so much before it becomes inefficient. Think the Gtm strokers I've seen have been on the 350 platform. Some TT stage 3 or big singles. The torque should definitely go up with the stroker, most likely more torque than hp.

Im so glad this thread came up if I could rep you a bunch in one day I would. Im going to give Z1 a call and get a price list going and possibly start ordering parts. Then I can leave the car with them on the way home from ZdayZ next year

[elliotty]

I would love to be able to get price lists in the thread to help compare/contrast options by desired RWHP goals. Built internals, strokers, head work, etc. That would be a GREAT resource! I am happy to help out.

i dont think the stroker kit is necessary. unless your going for bottom end power and no top end. It most likely will kick in the spooling time for tiny turbos, but going with a bigger turbo i dont think you will ever reach full boost in it.

But i take the over kill as a compliment g37hks dood. im doing it right one time. im not going to take apart the engine just to get to the block again. building it from bottom up. might as well. but ive also thought isnt this what building a motor is?

oh well just my input.

[Mr&Mrs]

My view on it being overkill is that you are nearing 20k + build. I own two 370z now both with expensive visual mods, and one with TT.

Im not putting another 20k into one of these cars I will just sell both and get a GTR if I even think of spending that much more.

A larger displacement motor will spool any turbo quicker. As far as it being for low end power and no top end, that's up for debate. I would think that cam profiles, any head work, and turbo sizing would be more of a factor in determining the shape of the curve. You'll definitely make more power down low, but I don't think we've seen enough stroked VQ37s to determine if they die off up top.

[elperuano]

Especially if using a big single turbo. Single turbo on a stroker kit would be siiiiick! R some big twins like Squeeze has.. With e85 n meth the power would be great. We just have to wait til someone can go down this path. It's been done on the 350/35 platform already. Built motor + corn fed = big numbers

[de_dust]

pretty awesome information! noob here, i was wondering if there are any info or parts from the gtr engine perhaps that would help with building this motor? i understand that the two engines are substantial different, but i am assuming there are more GTR built engines out there.

i came across this during going around the web, Nissan GT-R VR38 Engine Build - YouTube

it would be awesome if someone does this for our motor.

Overkill or not, I could only hope that if you do ever build your motor you use it to its potential! That is a GREAT list you have and with all that 600 hp would prolly barely scratch the surface of what your build could truly handle.

When I build I'll aim for 700+ and I'll make sure I run it at that. To me personally it's only overkill in any scenario if u don't use it accordingly, anything less is a waste.

Cool more power to you.
