hi will the vq35 de flywheel bolt up to the vq35hr engine ,if not does anybody no the difference thanks.

 

They are not the same from what I have seen. All the vendors have different sales for de and hr clutch/flywheels. I do not know exactly what the differences are since I have never compared the two. Here are some links showing a vendor selling for the different motors:

hr

hi thanks for the links it has the same amount of bolts from what i can see from what i have found out the senser is in a differant position so i might just be able to move it

 

You'd be wise to check the bolt pattern for both flywheels BEFORE you put your hard earned money down. I haven't measured them, so I'm no help there. But Nissan engineers changed so much on the HR that I wouldn't leave it to chance.

 

hi will do a, the flywheel that i am using is a custom crome moly flywheel just planning my next engine build if it doesnt fit ,i will have to make one to fit the hr but would be nice if it would fit. just trying to work out whats involved in changing to a hr motor

 

You'll need a LOT more than just drivetrain bits if you're trying to complete the swap from a DE to a HR. We detailed a HR swap into a SCCA T2-spec 350Z racecar in the last issue of Nissan Sport Magazine.

 

hi the engine is in a spaceframe race car i only use the engine every thing is custom made was looking at the hr because they seem a lot stronger and the higher revs will help my gearing and the seem they wiil handle boost better

 

If your app is a tubeframe racecar, then you'll have plenty of time to verify flywheel specs before installation. Are you running a 350Z body? What sanctioning body and rule set are you racing with?

You might want to post a few details about your car in your signature. It'll save some confusion in the future.

 

hi the body is a jdm toyota levin the car is running a forged vq35de the engine is mid mounted running about 650hp and weight is 1000kgs the class i run in is called osca what is a all in anything goes cars range from mazda rx7 nissan 350zs to trans ams race cars do u guys have any classes like that?

 

It will bolt up ok, The cranks sensor pickup rings are different and there are slight diff's in design.

 

It's a shame you have to run that racecar as a Celica. The VQ deserves a 350Z body. Did you know that fiberglass or CF 350Z bodies are available from Nissan Motorsports USA?

Here in the states there are tubeframe classes that race in Sports Car Club of America and unlimited class cars for NASA (all road racing cars).

 

yea would be nice to have a 350z body we used to run a nissan sr20 running around 550 hp but those 700hp chevs used to give me a hard time on the track we hope to devlop the vq to give a bit back have u guys be running the vq on the track there is only about 3 cars in nz what run the vq35 turbo so its a bit new to us

 

There's several Z racers (including GT2 tubeframe class) running VQs. Most are NA, as FI is not allowed in many classes.
