Turbo VR6 in 350Z
#221
Really? I think the 12v VR6 holds up to boost much better than the VQ35 any day of the week. A German Iron block with aluminum head, originally designed to be a diesel engine with less moving parts than the VQ does not sound like a unreliable engine in my eyes. I guess I'll find out in a few months...$5k for repairs? Isn't that more than that car is worth? You can build a bullet proof 12V VR6 for that much. You're right, sound is amazing compared to the VQ IMO.
And yes, Repairs were WAAAYY more than the car was worth....But Corrado are rare, and beautiful cars...and i didnt want to give up on it. I think the biggest problem with the VR6 is they have a huge problem dissapaiting heat. Almost all problems they have come back to this. So install a big *** radiator with a nice big fan....should keep the VR happy. I love them motor, sound awesome and a cool design, I think VW screwed up by giving them cramped engine bays with insufficient cooling systems.

Let's stay on topic, but what you point out is not bad for a 10+ year old car. You even mention the improper use of coolant that obviously caused further damage from the over heating. Timing chains should be replaced at about 100K and clutches wear depending on the driver. Shoot, I had to do two head jobs on my buddies Nissan 240sx within three years because the coolant passages would corrode and I would have to weld them and resurface the head to fix it. Any old cars require maintenance. I guess we can agree to disagree and move on.

not aware of any on the z at that power either, and if there is then its from a crap tune. any engine can very likely send a rod through the block if its got insane det even carillo h beams. saw a pulling tractor at the fair once snap a callies dragonslayer crank at idle because the det was so ridiculous it just got to be too much.
for 400 hp its a waste to swap a engine into the z platform since you can throw a used supercharger on and everything needed to get it to work and call it good. only exception is if you want the flatter torque curve of a v8 or intend to go for 1k+ in the future. personally then i would say def go for built v8.
i mean if you prefer the engine by all means but th vq breaking at that power level is just from either someone screwing up or manufacturing defect leading to premature failure and the engine being beat on vq's run that power and more all day long the HR handles the same amount of power stock. not to mention i went to high school who had two supercharged corrado's first one blew a head gasket so he used it for parts second one he bought in 05 the year we graduated. saw him in 07 and he said he junked both after he managed to break ring lands in two cylinders. probably his fault but just a perfect example if someone screws something up any engine is susceptible.
edit: dont take it as talking down about the engine or anything doing something is definitely better then what this forum has resulted to of paying shops to do stuff and the shops dont even bother to post anymore and trolls. just saying what others said is it dosnt really sound like the engine is any stronger.

Jeff, I think the difference comes in when getting to that 500hp number. As you can see, he picked up cams for $300 or somethin, turbo manifolds are cheaper, etc. Once the swap is done, the aftermarket prices are much much lower, so perhaps getting to 500 is cheaper? Can't really say. A big bonus to me would be the super spacious engine bay.
I don't know of any that are tuned proper that blow up with that. I see people screw up LS blocks and blow them up at under 400hp with no forced induction. Stupid people can break anything.

Just wanted to check in. Sorry for no updates, I have been studying for the PMP certification test for the past few weeks. I plan to take it next month so I have been studying non stop and don't plan any work on the car until after the test.

Ok, I'm back working on the car. I have the new aluminum housing to finish the cooling system as soon as the new tubes come in this week. I want to have the cooling system and wiring done within the next few weeks and then I'll move onto the turbo/down pipe.
Some other good news is an old buddy of mine is sending his DeLorean down in October and we're stuffing a turbo VR6 in it too. It'll fit better than the 2JZ did in my DeLorean because it's a LOT shorter and I won't have to move the transmission.
I'll have pics later this week of progress.

Here is the new thermostat housing and piping to the water pump. I used a thermostat housing from a Ford Contour V6 because it uses a proper bypass type thermostat and was perfect for what I needed. the cast aluminum was a little hard to weld but I got it sealed up well. I still have to finish the lines going to the radiator but that will be easy. I have my GM LQ9/truck coils on the way along with all the other sensors and things I need to finish up the wiring.

should fit, but it will be tight. Get that last coil pack closer to the strut bar but not under.
Also, careful mounting the coolant pipe to the car body. Any kind of flex in the motor mounts will cause bindings and may crack your pipe.

Thanks, I'll see how far back I can push them. For the coolant lines I have a good amount of flex available from the hoses I put in place for that purpose and my motor mounts should not flex much.

While I hate the idea of a VW motor in a Nissan, I cant help but admire the ingenuity involved with such a feat. Mixed feeling, but mad props on the custom workmanship. The purest in me still hates you though lol.

I can appreciate your opinion. I see you live in Orlando, I work in Winter Park. I'll give you a ride when it's done and you can let me know what you think then.
#233
I'll take you up on that offer bro. I'll also be able to give the forum a review from a 2nd parties perspective. Hit you up with a PM once I see you've announced its completion. GL

why not mount the coils in the space near the brake booster and just run the plug wires into the engine bay?
much cleaner like this

Thank you for that suggestion, I will look into that more. I was trying to keep the plug wires as short as possible to keep the energy up and EMI down, but I do see a benefit in keeping the coils cooler that is a plus.
