First off, I want to say "hello."

ok lets get to it. I'm a pretty big American car guy and know little to nothing about Nissan internals, but I have acquired a 95 maxima with 190,000 miles on it, and want to play with it.

simple question..... how much would it cost to rebuild the engine to make it a strong runner and have the internals ready for nitrous as well?

hope you guys can give me some insight.

 

Considering that you can find good used VQ30DE engines through national junkyard networks for as little as $250, I would say that the expense of an engine rebuild may be a waste.

Also, Nissan brought microfinished cylinder walls to the table for the first time in a car of this price level. A rebore will negate this, most machine shops can't replicate a microfinished surface. There is a guy on www.turbomaxima.com that shows some pictures of pistons and a refinished block. I've been meaning to ask him exactly what he's done... The pisons/rods he shows are Arias, and I think he has JWT cams.

The engines are strong to start with, but when my turbo blows up my 140k mile motor I may experiment with a built motor.

Hopefully some built motor guys will provide info about sources of parts, and some more insight.

 

Here is a better link to the car I was looking at...

For a fact, stock internals with compression readings on the high side of factory spec will take 100hp of nitrous no problem, perhaps 125hp?

Rods will be $600-1k
Pistons will be the same

Micro finish isnt that big of a deal when you looking to juice or boost. An average machine shop can reproduce this by using super fine sand paper in the last step of a hoaning process.

Find a low milage stocker and juice it, if 100hp aint enough(mid to low 13's) Get the oroginal motor done up.
