I have a spare VQ30DE, and was wondering what I can do to it to give it the most potential. It will basically be a project engine. I would most likely swap this engine with my current VQ since it's about 100,000 mile difference. I don't really want to buy anything, but tune the engine so I can maybe free up some power. So basically, I have a VQ30DE, and almost no money, what can I do to it to unleash most of its power?

 

There really isn't much if anthing you can do to it without money, somebody correct me if I am wrong.

 

fast and reliable cant be cheap, cheap and reliable cant be fast...kthnxbye

 

If I did have the money, what could I do?

 

What does that have to do with his question? Useless post...

 

From the sound of it, you're asking about INTERNAL work that could be done to make the VQ30 more powerful n/a, right? The reason i'm asking is because your questions are kinda vague.

 

If you had the money, you could get 00vi. Some NISMO heads, high compression pistons(or VK45 psitons). Upgraded oilpump, new cams, headers....

But since you dont have the money.....

 

Anyone no of any company other than JWT that manufacturers cams for the VQ30????

 

You can use the HKS, Nismo, Tomei, ect.... cams with spacers IIRC.

 

But what engine are these cams meant for? And where can you get these spacers? And where do they go?


Where can you get these NISMO heads? Any specific kind of oil pump? And where can you get the VK45 pistons?

 

VQ35. spacers go at the end of the cams.




Nismo heads cost more than our cars haha. VQ35 heads on a 30 still need to be tested. VK45 pistons from the dealer or junkyard.

 

haha sweet man! thanks

 

are you asking about what kind of machining can you have done?

port and polish heads/ports...valve jobs, knife edge the crank journals, mill the block/heads, swain coat heads, balance and blueprint, etc?

 

Insert dead horse here...

 

Take it all apart and p&p the heads, take it all apart and put it back together, make sure its all perfect and clean, should get you more hp stock then your current worn out engine, just in the fact that its basically new.

 

if you have a lot of cash, there are plenty of things you could have done at a performance oriented engine rebuild/machine shop...

 

^^^ very good info thanks guys.

 

what nissan did the VK45 pistons come out of

 

2002+ Q45, all the M45's, etc.

 

So you can use vk45 pistons in the vq30? What type of power and stress can they handle compared to the stock ones?
