Hey everyone. I am new to this site and im looking for some help.
I have a 93 300zx NA and im abviously looking to go TT. I looked into buying a front clip and doing a full engine swap. I knew i wanted to swap out the turbos as well in this process whihc would call for an engine rebuild. All of that together was out of my price range so i decided, why not rebuild the NA i have now for the upgraded turbos? I read that you can do the TT swap buy rebuilding an NA engine.
My problem is that im looking for womeone who can do this NA to TT engine rebuild. they need to know what theyre doing and the closer to VA the better.....So if you can or know of anyone that can do this rebuild thats in the VA,NC,MD area that would be much appreciated.

call tidewater Z.
but what's that you say? you're looking for a womean to do it?
there is a write up about the specific deferences in the block. i'll try to find it right quick.

just sell the N/A and buy a TT
So i know that buying a TT is just the smarter way to do it BUT the engine knock is bad enough that i wouldnt be able to get much at all by selling it...plus id be rebuilding the TT motor once i got it so i could upgrade turbos...? I might as well stick with the engine i have or at least thats what i feel is smartest.
and no i down want a woman to do it. i want someone
and no i down want a woman to do it. i want someone
no no its not that the engine swap is outa my range, its that doing an engine swap and rebuilding that same engine at the same time is outa my range...thats why im just gunna rebuild my NA b/c ill be rebuilding an engine either way so i might as well not buy a new one.

What makes you think you need to rebuild a VG30DETT to install larger turbos? My longblock is entirely stock and I run GT2530's. As long as the compression is fine, there is no need for a rebuild. Save for a while, sell the NA, buy a TT.

on that note, what does cause an engine block to not last up to the 300k miles that others have? is it too many shifts too close to red line, or missed oil changes? small crank case ventilation issues? if you can put bigger then stock turbos on an already used stock block, how can you be assured that it will last any amount of time? if you have to take it easy, why put the bigger turbos?
this certainly isn't an argument, i'm really curious. i'm just wondering what i have to do to keep my engine running as well as it is. i change the oil plenty, i'm just wondering how often i should be able to do the 6,200 RPM shifts that i do so much.
lol this is such a noob post. i know how to generally take good care of an engine, i just don't know how much high end shifting this stock block can handle, and what people do do to ruin their engines prematurely. i don't want to get on that track

its EVERYTHING. proper and perfectly timed maintanence owner parts quality proper diagnosis. weather storage.... its everything...

Just overall care. If you beat on any engine (even a built one) without taking absolutely meticulous care of it, it won't last long. Bearings wear out. Seals wear out. Rings wear out. etc etc etc
But if you fix things when they break and do the routine maintenance (the tune-ups every 60k miles and things of that sort), any engine can last a long time.
Putting aftermarket internals in ANY engine doesn't assure you of ANYTHING, let alone that it'll last long. More power means more stress on the engine, higher rpms means more friction, and that's that. Stress and friction are what wear out and break engine parts. The bearings and rings wear down, and that's when it's time for a rebuild.
People do things like forged pistons and aftermarket H-beam rods to try to handle the extra stress. But to date, people have done up to 751rwhp on a stock long block (no joke there). Sean Wagner did 744.4rwhp on a stock rebuilt long block with swain coated pistons (and that car has been running fine for at least 4 years now, if I recall correctly). When I was at Ultimate Z, one of the owner's friends was a guy named Stan who had a 2+2 TT that recently rolled 300k miles with a Sport 600 + nitrous setup. The stock internals can handle plenty of power (*IF THE CAR IS PROPERLY TUNED*), but stronger components (such as forged pistons) will resist damage more. (If you detonate on a cylinder with a forged piston, the piston is less likely to crack than detonating a cylinder with a cast piston.)
And as for "if you have to take it easy, why get bigger turbos?"... that's just a dumb question, no offense. McLaren F1's require servicing twice a year. Ferrari Enzo's require the same every few months. etc etc etc. You have to pay to play. If you want high performance, you're going to have to maintain the **** out of the car whether it's a built block or a stock block. My car produces over 550bhp on my street settings with over 125k miles on the engine, and I use it occasionally. My compression is just fine, my ECU tune is rich (to resist detonation), and the car handles it just fine. I replaced my rod and crank bearings last summer because hard driving wore them out... that's the price one pays when working with an engine that has miles on it. No, you don't have to take it easy... you just can't be a retard. And you have to service any performance vehicle to keep it working right.
So when it comes down to it, aftermarket internals on a 300ZX that's making less than 600rwhp or so are just preventative in the case that something goes wrong, or a mod of opportunity. When I blew my first engine 4 years ago, I did Wiseco pistons because I was rebuilding it anyway... might as well do the forged stuff. When my current engine's compression drops to an unsatisfactory level, I'll be swapping in those same Wiseco pistons from the old engine... not because 550bhp needs forged pistons, but because I might as well, and it can't hurt.
If your engine is old and tired, rebuild it with the best parts. If it's healthy, there's a saying... if it ain't broke, don't fix it. And if you replace things when they need to be replaced and take good care of the car, there is no reason a high-horsepower car can't last you a long time, whether it's a stock block or a rebuilt one.

i try to stay on top of the maintenance. oil changes more frequently then recommended, and i surely don't drive it with any sounds that i can't identify coming out of it. but that pretty much answered my question. thanks a lot!
but you mentioned changing bearings. i have heard from an engine builder that changing bearings was a bad idea because when they were worn, the crank was worn, so changing bearings would speed the rate of wear. he said always change or turn the crank when changing bearings. would this be not so true concerning the vg30de because the crank is stronger?

I had my crank reground with oversized bearings when I did it last summer.

What good is knowledge and experience if you can't use it to help people?
Unfortunately, there are some douchebags on every forum who don't value my input.
