New Z or TT my 370?

Spooler

The VR38 and the VQ37VHR are not the same block. They are way different. The VQ oil pump is ran on the crank. The VR38 oil pump is ran via a chain on the crank. Totally different. The VR38 block is closed deck with 13mm head studs. The VQ is open deck with 12mm head studs. The engines are totally different. Can't leave off the drive shaft running through the factory oil pain of the VR38. VR38's are taller also.

Again, same casting. Dressed up for boost.. I forgot to mention AWD dressings.. my bad. Pumps and chains should be auxilary to the block with the same exact bore, and coolant passages. Of course all that heavy obese godzilla crap would be deleted. LMAO Besides, its moot if I'm just plugging in a top end to a vq bottom end dressed up for boost to my liking. All you would really need is forged rods, and lower comp pistons to have a reiable turbo car(bottom end wise). If you want to crank out high boost, yeah.. you'd want to close the deck to prevent the jugs from wiggling.. like nissan did. They already spent millions here writing the playbook, might as well follow it. It is a highly developed motorsport platform already.. they just didn't put all the parts on it that I want cause it would've taken sales from their flagship gtr pig. Nothing stopping me from taking those parts, and configuring them how I want on a proper RWD manual.

"The VQ oil pump is ran on the crank. The VR38 oil pump is ran via a chain on the crank."

The crank is not the same. The oiling difference I would assume is for a dry sump. The VR has 2,5 mm longer stroke. So yeah, def different crank.. Same block, coolant passages and bolt patterns tho.

"The VR38 block is closed deck with 13mm head studs. The VQ is open deck with 12mm head studs."

1mm drill and tap, then call ARP. Done. Just needs to be the same pattern. The deck, again.. put whatever liners you want in it. Doesn't even have to be the same material nissan ran. Hell, put iron sleeves in with closed deck, and call mahle for some pistons. I like JE too. You could probably put in the VR sleeves even. The material you choose for sleeves determines which pistons you can run is all really. Closed deck is really necessary for high boost apps. Hence why nissan put it on their boosted version of the FM sports car platform. On low to moderate boost, you wont see wiggle. Especially if tuned properly. My 944 has an open deck. I put 50k on it with 16 psi.. no issues. Again, decking, oiling, sleeving.. this is all ancillary to the actual block/crankcase. All the rwd nissans share many of the same core parts. They do this to save money. and manufacture a sports car people can afford vs the GTR hardly anyone can afford. It's a tuner car, it was literally designed to be finished and tuned by the end user. If you want nissan to dress your z chassis up from the factory with race tech, and performance to their liking, its called a GTR. The GTR doesn't do it for me. It's a bloated, ugly pig IMO. Not how I would dress it up, thats part of why they make the z the way they do. It's got to fit a budget. You could spend200-250k on a nismo gtr dressed up just how nissan thinks you should want it, or you could buy a z for 40-50k, and for another 100k(max high number) plug in the parts and configure it how you want it. RWD manual FTW. I'll totally highjack their engineering, and develoment tho. Put it all into one car to my liking. Mwahahaha. They do have tasty milkshakes... Sip, sip, gulp.

Oh, the 6 speed also might not line up with the bell housing. It should, but if not its not real expensive to have an adapter plate fabricated. Again, should be the same pattern

What's the deal with the borg-warner 6 speed the gtr briefly had? I'm assuming the diff wouldn't work. That borg-warner lump should be crate ready from borg-warner off the shelf with plenty of parts availability.

Spooler

LOL, you don't know crap. Now I am tired of dealing with your dumb butt. Have a nice day. Go back to Facebook.

370Z944

Wow.. ok.

Thanks for such a technical, and concise refutation. Funny, cause I've literally never had a facebook account. 23 years later after finding out about it from a from a friend that was attending upenn at the time. Was pretty obvious from day one.

LMAO. So far you've told me nothing thats not easily modded. Bigger head studs.. cool, bro. Oooh, ahh. lol Makes sense.. boosted motor. That's why they make these things called a tap & die. Bigger bored out threads=bigger studs. Pattern is same, coolant passages are same. There were people like you on rennlist when I first did this with my 94I grafted a 951 top end to a s2 bottom end, and 968 crank, with a 2.7 89 944 head with proper passages that lined up with the 951 intake that connected to all the upstream turbo goodies. It's not possible they said, very few have done it right, it will be too expensive, blah blah Now there are likely over 100 3.0 builds in the wild, and an entire registry for them on rennlist.

Don't worry, sweety. I'll probably start a thread about the build just to see if you're right or wrong once I actually go down that rabbit hole. Once the 44 is done. I'll probably get a 4x4 and the nissan will get the proper treatment too now that the warranty is up. should be done by fall.

I'm figuring someone around here knows the nuances already. I'm still not seeing any reason why not. Then again, I'm just a "dumb butt". What would I know? That must be the case. That's all the convincing I need.

Rusty

I like to know what in the hell you are smoking. Because it's killing your brain cells. Spooler has done more research on the 3.7 VQ motor than anyone else I know. His first motor made over 800 HP. Second motor made over 1,000HP. Who knows what his 3rd motor will make. It's in the planning stage now. When he speaks, you better listen. The man knows his chit.

The VQ and VR motors are 2 different motors all to together. There is nothing the same. If there were. There would be a thread about it. Nothing interchanges.

His response clearly is indicative of that.

I'm the one speaking gibberish? Y'all fell for it, not me. LMAO I see. I must just be dumb.

What numbers? Please, tell me.. if I can get a chem degree from AZ state, I'm pretty sure I can understand what oh so sage knowledge his highness has up in his head. Cause so far, nuh uh, pointing out the crank is different, and it has larger head studs(boosted makes sense), then stamping off, and pouting isn't saying anything. Is it o-ringed too... ooh ahh.. thats some proprietary nissan tech there. LMAO

"The VQ and VR motors are 2 different motors all to together. There is nothing the same. If there were. There would be a thread about it. Nothing interchanges."

Nothing you say? Same bore.. nearly the same stroke. If coolant passages are the same, I can almost guarantee the heads line up and the rest.

Since when do woke kids rock fire breathing turbos and no cats??? LMAO News to me.

BettyZ

And the childish woke come for Spooler! This thread is cancelled in five, four, thr... oh wait I forgot, the concept of numbers are/is/they colonialism.

They have been after me for the last 3 years. Nothing new. LMAO!!!

370Z944

I'm woke? Oh man, I'm just learning all kinds of things about myself that I never knew. From strangers that I have never met me on an internet forum too.

Seems someone has regrets about their Biden vote? Was it the fence, or the grab 'em by the puzzy" that triggered ya?

370Z944

Ah, I'm a dipchit and a troll.

I'm crushed. lol

Welp, that explains it. Who needs numbers? Oh, and schematics? It clearly doesn't work, a random internet guy on 370z.com said it doesn't. He made big numbers... he knows everything now. Bahahahahahaha

This is fun.

Seriously tho, why wouldn't it work? Still waiting on a valid reason.. Head studs aren't it, sorry. "it would already be a thread if it did" is not a reason.. sorry.

Rusty

Start a thread and build it. We will all be waiting on you.

Like I said... around fall. The 944 isn't finished yet. I ripped it apart for a full ground up thats almost done.

I could start a thread about what it would take now. Brainstorming, and going down the rqabbit hole I guess. It's gonna be like fall before I can start buying parts, and actually doing it tho. Of course after I've crossed all the t's and dotted i's.

Spooler

One question. What is the biggest problem with the VQ37? Got to know what you are trying to correct. Otherwise, you are just another idiot trying to install GTR parts because they are better.

370Z944

Who said anything was "wrong" with the vq? The VQ is great normally aspirated. Just how nissan engineered and developed it to be. It does not have boost tho, and wasn't dressed up for boost from the factory. That's the VR. I'm not correcting anything. Why plug in aftermarket crap??? Better is subjective. If they fit, they fit. I'm just looking for an OEM route to plugging in turbos. Simple as that. The vq heads likely wont line up with the intake, and not ideal for boost. I mean, if the intake lines up then you could even use the vq heads in theory. I wouldn't run a stock vq head for boost tho. I's assume nissan dressed up the heads for boost too.

I don't know what parts you guys are looking at, but the ones im seeing all share the same core parts bin so far. Dude, it's nissan, not pagani. lol Are you familiar with the FM platform/chassis? the same chassis ALL RWD nissans have? Pretty sure the GTR also uses the same chassis.. in theory I could chop it down, and build a perfect altima from it. LMAO They did not develop a custom crankcase and block for the GTR, they just dressed it up as a "VR". Also note the factory nomenclature vQ vR. That's the thing with the GTR, its priced with exotics, but it's basically just a nissan parts bin special. FFS, they haven't even changed the powertrain in what? 15 years or something? Why do you think that is? Cause it costs too much for a failing nissan who is hanging by a thread to develop a bespoke motor or even chassis for the GTR. Lot of smoke and mirrors going on at nissan.
