its not worth the money personally, build up a stock engine with a big turbo and go nuts with it

lol... so set up a carb-turbo and paint the car midnight blue and have your very own "Devil Z"

a friend of mine has a 350chev in his 280Z that car rips, very very fun...
i know a guy(from a diff forum) who just bought a near mint 280Z for cheap, and is now putting in an rb26dett... its gonna be one of the nicest Z's in Canada when hes done...

turboing a 30yr old engine is no cheap and easy task, especially if you didnt have the carb-turbo engine to begin with... first off you need to do a complete rebuild, add in forged EVERYTHING, get lower comp cams(if it was non-turbo)... do you think its gonna be cheap to get all these parts? do you think its gonna be easy to find them? and when its all said and done the most amount of power you could possibly make is gonna be about 550rwhp... which is WAY more than you need since you wont be able to get much traction...

swaping in an rb26 or a v8 is gonna be cheaper, very easy to do(its been done many times) and nets VERY VERY good results...

Where do you get your numbers? You don't need to do forged anything to upgrade to turbo.

The engines are pretty much the same with some minor ones.

did you see a single number on my post? no no you did not...

i say go forged internals because on a stock set up you will fry the internals in no time while having fun... ive seen it happen numerous times on numerous different makes and models...

yes to turbo a car all you 'need' is what you posted... but and this is a BIG BUT if you want the car to be reliable and last then you're gonna need to go forged...

cheap, fast, reliable... PICK 2

as for going rb26, it would be easier to go rb25 less work involved and you can see very good numbers come from them, but again if you want more than 400rwhp you should go forged or you are just waiting for something to happen...

on a stock engine thats almost 30yrs old... bad things happen alot quicker... also findingforged internals for engines of that era isnt cheap or easy...

it will be cheaper and easier to go rb than to 'properly' build the stocker up... and even cheaper nd easier to go v8...

well like i said over 400rwhp on a rb25 will require forged internalls as depending on the size of your turbo you will be pushing over 20psi in the cylinder...

on an 30yr old L series engine to get the same numbers you are gonna have to do a solid rebuild anyways, so while there might as well go forged... cause when you are wanting big numbers and big power you dont want to be thinking " will my internalls hold up to this abuse ? "

you want to know they will...

also to get reliable power out of a rb26 anything over 450awhp(i speak in GTR terms since i own one)500rwhp you are gonna need to go forged... and expect to be paying over $20k on the total build... rb26's make easy and reliable power upto the 450 range but past that and things start to get very expensive, very fast... and things will break.

everything is dependant on the goal for the build, what the car is intended to do once done. etc etc etc... if you just want more power, how much power do you want?

i always find it very difficult to give good advice when people ask such open ended questions in regards to builds...
