Nissan motor or upgraded motor?

[Ill give u a head start]

I have finally decided after weeks of deliberation lol that im going to keep my Z and fix it up right. For those of u who dont already know i have a rod knock in my 93 TT. I have narrowed down my options to either a brand new Engine unit from nissan for $3200 or a new motor from i think it was Z1 motorsports with the upgraded pistons and piston rods. My dad isnt too crazy about a motor that has been fiddled with by a performance shop being the motor with the upgraded pistons. He says it will not be as reliable as the motor from nissan what do u guys think? The car does have 92k miles so if the turbos were to go out i would probably go for upgraded turbos. So in my situation which motor would u go with?

I would go with the upgraded motor, it would be better for the $$. Oh, and you can get a brand new motor from nissan cheaper than that.

when you say brand new motor from nissan, do you mean 0 miles, cuz that sounds very nice. but i do think you can get a new engine from nissan for cheaper than that, you might even be able to get a very low mile engine for around 1500, depending on where you are located, but i would go for the brand new engine, i mean it would be nice to have the other engine with the upgraded pistons and everything, but you dont know how good of a job they did putting them in, and there are other miscelaneous factors you should check be4 putting your heart into it.

also if you get a new engine from nissan it will most likely come with some type of warranty, if you get some kind of JDM engine from z1 you wont have that option, and also it most likely will be illegal, and wont pass emissions, at least not if it comes with the JDM turbo manifolds. but i suppose you could try and keep the manifolds from your old engine.

Stock motor can handle a ton of power. Unless you're going for very lofty power goals, you'd be better served with the Nissan motor. A built motor is always nice, but with Z1 doing the work....do you know its done right?

[TT2+2]

not to direct you either way, but i have the z1 stage 1 longblock in my z and love it, if you plan on upgrading in the long run, that is the way to go. i've put 13000 miles on mine since i had it put in in may and it hasn't had any problems at all

the big point is to look at what you want the final result for your car to be

if you want a performance monster then go with the upgraded motor, if you just want something that is reliable and have no plans of upgrading, then go with the stock nissan motor

and btw i passed md emissions with my entire setup after i put my cats back on with 555cc injectors, downpipes, upgraded turbos and b&b cat back so you shouldn't have a problem either way and i stress "shouldn't" there are deffinately exceptions

Z1 is a very reputable shop, and will do good work with a built motor. This means a lot coming from me, as i dont really like Z1...it all comes down to future plans. If you plan on hitting high HP numbers, might as well get the built now, other wise youll be buying a new motor twice (or atleast all new parts for the motor)

has anyone tried amzperformance for their excort engines?

[eddiezed]

I have a 93 tt also and will be buying a new engine and since my current engine has been resealed Oem turbos rebuilt I will probably drive it for Approx 5,000 - 7k miles while my motor is purchased and internals as needed replaced i.e. turbos, injectors, manifolds, downpipes, turbo piping, whatever it takes to achieve a 520 rwhp beast. The key is what are you trying to accomplish. I just want the available power and reliability of the original engine with some smart modifications.

Go with OEM. Nissan motor (especially the VG series) are damn hard to break. I wouldn't fiddle with a pre-modded block.

[eddiezed]

Definitely OEM crate motor (Nissan Long Block Assembly) next is how and how much. with an new turbo (HKS GT 2530) one piece driveshaft (ACPT) downpipe turbo tubing Not including engine at least 6Kmore. Any glaring ommisions.

where can you get a new motor for 3200? thats is way cheap

[Ill give u a head start]

if i were to go with the oem nissan motor it would come with a 1 year 12,000 mile warranty im not sure if there is an extended warranty available or not ne of u guys know? Im leaning towards the oem nissan motor but my question is that if my turbos go out down the road and then if i was to buy upgraded turbos to replace them would the oem motor be able to handle it?

the original price quoted to me by nissan was $4,000 but i have a whole sale account with them and with the discount it came around to $3200

Depends on how much you are planning on boosting. If it's any consolation there are many SRs which are not engineered to the standards of the VG that have 600 horsepower with no internal mods.

oh and does any1 have reccomendations of a place where i can get the new motor put in? I live in northern CA. I found this guy that works out of his garage and seems to know his way around the Z and was recommended to me by a car salesman at nissan saying that he did his NA to TT swap. My only concern is that he wouldnt be able to have any type of real warranty on the labor part of it. oh and he said he would charge me $1,000 for the labor.

p.s i got an estimate from nissan the other day and they said that they would charge me with parts and labor $9,000 dollars!!!!!! i thought the guy was joking but nope its the truth... what the hell is wrong with them?

Dealerships. That is your problem. The Ford dealership charged me 1k to fix a broken rear window on an Expedition.

sure, dealerships are expensive... but they're not evil, they're just like any other auto shop - interested in making money. and what you really paY for at a dealership is pure nissan experience and the confidence that any work done will be done right... however there are plenty of places to get work done correctly, its all about finding a mechanic you can get to know and trust to help with the work -
