my first rb26 swap on my 300zx

[MYFAIRLADYZX32]

Quick question since I'm still driving my car waiting on The RB engine I had an issue start happening 2 days ago every time I would go turn on the car in the morning there would he this ugly screeching noise it would go for about 30 seconds and then it would stop today it did the same but lasted longer plus when I went to rev it it got louder finally it stopped and i got the car moving but when I came to a stop and drove again bam screeching again then i would go away after a while it stopped I've heard it might be the belts or just because of the weather i checked the belts one side is tight the other is loose so I'm thinking it might be because that side is loose that it's screeching it only started doing that 2 days ago

Belt slipping.

Is it bad if I drive it like that? I mean I don't drive it alot now just take it for a few laps around the block and park it again so it doesn't just sit there.

Since it's really not that big of a deal on a Z32, I'd tighten it...and honestly, this kind of thing is something you best get used to- checking the engine bay constantly, and being ready/able to address small issues on a relatively routine basis if you are seriously considering an RB-swapped vehicle.
As NoLimit mentioned in detail, the age of the car and parts and fact that engine and drivetrain parts from different vehicles swapped into another car with all of the above aged well over 20 years means that squeaks, leaks (oil, boost) and other minor adjustments and fixes will be your life, or that of your mechanic and should be considered a no-brain, "time to get to work" call from your prized Franken-Baby...
If you want a car that you start every morning and drive away and that acts basically the same each and every time, you need to forget ALL about a swapped vehicle.

oh I don't mind all that man i love everything about this car i was just wondering if it would be an issue to let it be loose it's not that loose but you can tell it's loose and i like that Franken baby haha nice and yeah i am going all the way through with this swap I already found a place that can do it they know about it guy told me everything they where going to do plus my end end goal is to get that RB to 800hp so they broke it down to the last part they've here going to install and how they where going to build the engine.

OK, and while you're at it check to be sure it's not a leak from the PS reservoir hose that's leaking onto the alternator belt and pulley and causing the squeal. if so, you want to fix that leak ASAP as it will take out your alternator which starts to cause larger costs...and is the reason you don't just live with it awhile so to speak.
Just more of the kind of thinking you need to use on your own right off the top when owning/maintaining a higher end, performance vehicle...

sup guys its been a while since i last posted here and well my N/A engine blew up and the RB swap is out the window now on the bright side i got a VG30DETT but ive been having a bit of trouble putting it in considering its going on a N/A model i was wondering if anyone could give me some tips on this swap and if i should get a tt radiator right now im gonna go with the radiator it came with (short on money) i need to know if it will make a difference running that

You must run a TT rad if you are going to run the oem IC piping routing as the NA rad is to wide.
