Hey Guys

before you all tell me this is stupid and impossible, i already know im an idiot, my wife reminds me every day

money is not a problem, im definitely not rich but i can afford to spend a bit on this project

i have a R32 GTR, i wanted to do a build and lots of the local tuners were not happy to work on stroked RB30s, they say they will not hold the low end torque im looking for

they say the crank girdle will blow out, regardless, ive given up on that idea and instead of just building the RB26 i wanted to see how silly i could be

i found a local guy who has a VR38 for sale, im happy to pay the price he is asking 22K (complete engine turbos diff loom intercoolers)

i found a guy who will make the adapter plate for the bell housing and engine to fit together

i found a ECU to get it running (HALTECH)

i found a experienced tech guy to fit the ECU

i found a guy who will make me the custom drive shafts needed, and the front end "tail shaft"

i found the 2 throttle bodies that i need to make this work (it needs to be a cable system)

my question is, has anybody done this, i searched and only found a 200sx, but no skylines

i would love to hear from someone with experience in this area, im sure this has been attempted before

i cant be the only idiot

Someones done it with s15, clearance issues with the bonnet though. ( custom bonnet)
Your main problem is clearance between struts.

The vr is a very wide engine.

vq conversions might help a little

I can't see how VQ conversions would help, they're a very compact engine, the vq30det is quite small

I said a little...lol.
First thing he should do is get the tape measure out...

The vq35 is actually fairly similar.

Biggest hurdle will be turning the front wheels with that engine, if it even fits in the engine bay.

Edit: When I said hurdle I really meant clusterf*ck. Even making it work as a 2wd would be difficult and pointless enough.

If he has the money, that should not be a hurdle.
There will be alot of fabrication, and im sure he knows this, obviously its not a simple drop in, and getting rid of awd most likely needs to be done.

Cant put a man down for having a dream, hell if he can do it, id be very impressed and jealous.

The task of aligning the engine's front driveshafts laterally, longitudinally and vertically to meet the GT-R's half shafts, while making the engine and transmission fit would be hard enough. Then you have to consider front diff ratios most likely being different to the Rb26's, meaning custom crown and pinion ratios etc blah blah $$$$$$$

Has the OP ever been in a RB30 powered Skyline? Or even a running RB26? Why do you seem to need more power/torque than pretty much every other Skyline owner ever?

Edited by colourclassic

Maybe he wants to be different?
I doubt he can keep awd with a conversion like this anyway>

RB30s arnt the most ...realiable...

You would have to put alot of trust in the builder.

Maybe he should've bought an R32 Gts instead then.

RB30's are the most reliable. What would make them unreliable?

You would hope when spending thousands of dollars on an engine that the builder would know what he is doing. It's their job.

If he can pull it off it would be awesome, but it seems like a huge amount of money and time wasted, when there are proven options available which have been done time and time again, with good results and at lower costs. Chuck a Turbo LS into it if you want big RWD power and low-end torque. It will cost a quarter of the VR38.

Ive heard of horror stories with rb25/30s

And personally know someone that has had....problems......

That said, if its built properly it should be fine :P

Upto choice really, if he wants it just for tourqe...then yes...bad idea.
But if he wants it to be different and unique, i say go for it!

Edited by jay-rod

Vq and Vr are nearly the same engine.

Would be a great swap to see, especially if you can keep the AWD, but I would just stroke a Stagea VQ35 to 4.3L before wasting all that cash on a Vr38.

What is the problem with the electronic throttles? The newer Haltechs run the twin dbw throttles.

The rear ratio would be fair simple as there is a Fark load of different ones as nearly every RWD nissan has one, even the Navara

Fark the Haltech, look into the Syvecs S8, it is hell expensive but does drive the drive by wire throttles and will never need upgrading

This is something I have contemplated for my R32 when/if the 34 ever gets "finished", lol as if

Look up the MotoIQ time attack R32 GTR, it has one in it with a Holinger

wow thats a lot of info

well ok,

it HAS to be AWD or its not worth it,

the diff ratios are the easy part, and CV joints are much more forgiving than people think,

the diff and hubs can be misaligned a bit and work fine, the whole point of the CV is the flexible transfer of the power, they have a range they can work with

the biggest question is will it fit, so jay-rod is right, we have to get the tape measure out

and i think people forget the "waste of time/money" expression was used before, on people who wanted to get 1000hp out of a 2.6L

and now guys are doing that all day every day.

in my mind a car with the same engine as a R35 but 200-300 kgs lighter is a MASSIVE incentive

just a small increase in boost on the stock engine some tuning and we might crack 10 seconds

and the engine would be relaxed and comfy so it will last longer,

then if it worked, a big IF, people would know that its possible and try other interesting builds

Interesting idea. But what is actually making you want to do it, over say, an RB30 stroker? Spend the extra cash on a dry sump..... Build it properly and it will be fine.

if i am going to do up and engine it would have to be the vr38 its the easiest to get stupid amounts of power from

the VR38 engine is happy pumping out 500 HP all day every day on stock internals, some even say it can be pushing 600hp at the wheels

it comes on boost very quickly

has VVT and all the modern crap that will let it smoke other cars off the line

i want a very usable car that is a monster street racer

the GOAL, the aim of the project is to beat 1000cc motorcycles like the CBR1000RR

my mate is getting smug and needs to be taken down a peg

the reason im looking at this engine, it has a integrated front diff already in the right spot

and if we want to do any stroking and forging, 12k can buy me a 4.6L stroker kit

that amount of low down torque would make any motorbikes i race fall over with fear on the start line

Do it!

I would do alot of planning before buying anything though, that way if you find something that will screw you over.

Read over the Vq thread on his conversion, will give you alot of info and his issues.

You will most likely need to fabricate new exhaust manifolds,.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
