I probably wont' even spend 5 grand on mine.

i think the motor is like $5k. thats what i was saying...surprisingly cheap for what it is.

actually... as a matter of fact, the rods in the z31 are forged as well... if you have what is known as a 'w-series' engine in your z31 then feel free to boost the bejesus out of it... stock the internals are good to about 500hp before the ring lands start to shatter... i was pleased to learn this... the w-series motor was put in the 87-89's exclusively i believe, i'm not sure if all of the turbo's got one or not, i have yet to check if mine's a w-series engine, when i get around to it i'll be sure to be crossing my fingers that it is one....

How do you know if you have a "W" series motor? and was it ever used int he 86? or just 87-89? thanks!

there's a serial number on a plate at the back of the engine on the passenger's side that's either stamped with an "AXXXXX" or "BXXXXXX" for the regular engines or "WXXXXXX" for the w series engine

sweet deal...still cast pistons eh?

[DeleriousZ]

yeah, unfortunately... oh well... $600 for pistons is still a lot cheaper than $600 for pistons and however much for rods

yeah, wiseco charges $5?? for pistons and Eagle charges $6?? for rods. and they are the cheapest you can get.

Yea...but that's for JUST the motor! Not counting the turbo and all related hardware (another grand or so...around 1500 for what I have in mind...) any other external stuff (ignition parts, intake parts, exhaust parts, etc) or installation. I'm shooting to have my engine built, running and installed for around that much...

Oh...and the W series VG30E(T) was only found in Z31s from 4/87 on...so if you have an earlier 87, you still get the shaft. Don't mean to shit on anyone's parade...

This is one of the many reasons why that '89 I found was SO fucking sweet....

Ehhh...not so much.
Check this out: The guy I bought my Z from said that he swapped a motor from an '87 300ZX and put it in my '85 car. There was no way to tell if he was telling the truth (as far as I knew) until the motor was out.
Well guess what?! The motor is out, (and has been for a while...) I checked the block today, and voila! There's a big 'W' smiling back at me!
How sweet is that?!
The number is: 005474W

[DeleriousZ]

i can't seem to find the stamping.... where are you looking? lol

[drumpet15]

Lol, the passenger side deck is where I found it

yes, but you still will not have a professionally, highest quality parts, built VG33ET.

they way i see it... that motor, a properly sized turbo, custom manifolds, custom intercooler setup, custom intake, and larger fuel injectors could make one of the most responsive HIGH HP set-ups on a Z31. think of the extra response you would get from having another .3L spinning that turbo, response would be amazing. and it may be more expensive than other set-ups but i bet this set-up would be absolutely mind boggling for the money.
