VG30DE- PROS AND CONS?

Post by **ZWHEELMAN** » Tue May 13, 2008 5:47 am

What are the PROS and CONS for VG30DE. Would you say a VG30DE is a good or durable motor? If yes what makes them good or durable motors? If no why do you not think they are not good or durable motors?

The engine itself = durableThe wiring harness/electronics running the engine = PITAI have worked on several VG30DE engines with very high milage.The only issues I see with them are the electronics just not holding up. Mainly harness issues. The only internal issue I have seen with these engines was on an imported junk yard engine (some call them JDM engines) with excessive end play in the crankshaft.

Internally balanced and forged. Stock bottom end is said to be able to take 25+ of boost. Pretty durable if you ask me

If you run them low on oil, you most likely will spin a bearing or throw a rod.

Yes only the VG30DE is susceptible to this type of abuse...all other engines are superior!!!

Well they are less likely to have a piston problem or something in the heads thats related to lubrication. If you push this motor at all, boosted or not, the bottom end is what you have to worry about mechanically since thats its weaker point.

if im not mistaken the biggest problem is with the belts they have to be replaced after 60k or you can ruin the heads but they have kits now that are good for 120k because im looking into this engine too thats what i found but good ? though

biggest pro w/VG30E ... all the aftermarket support. All u have to do is use Z31 stuff.

Actually... the VG30E(T) has pretty much no aftermarket support. Most of the stuff for them is custom or done by Z31 enthusiasts. They don't have near the support the DOHC VG's do at least.

Listen to mtcookson! He is so right! The after market support is twice as strong for the DOHC Vg30DE And the VG30DETT than all the other VG series! Come on do a little research before posting! Im not saying that there is no after market support for the others but the Z engines are at the top of the list as far as tuning companies are concerned due to the money issue! Sales? Ya know!

Ok You say That the VG30DE engine has excessive play in the engine Well what about The VG30E, I just recently had to change the crank shaft pully thinking someone had put the wrong one on it. Afterwards finding out after the new one was installed that the crankshaft is now bent, Knowing this i am just going to swap it out but need to know about this Vg30de is it worth swapping and where is the cheapest place to find used engines for my maxima? And do you have another engine you would recommend?

One simple word: DURABLE.

They certainly seem to be well designed and built engines. The VTC system seems to be problematic on some, however.

i'm bringing this post back.

I own a '91 VG30DE...

knowing nothing i have swapped this motor into my '90 de shell. It was a JDM scrapped engine. all seemed well until i tore into the timeing and found out it had the timing belt installed improperly (among other issues). Bought a new oem crank balancer with a oem
new lower timing cover. generally all is oem - this is all i know to be good... anyways i
had wiring problems due to not replaceing all the external wiring.
they are faulty at old age.
now after Gordy of greenfield fixed them i went fast as told not too and my C.A.S. is making a clicking noise and revelations are jumpy [ put-put-put ] from idle to acceleration.

I love this car - know hardly any mechanics - was told i chose a hard vehical to learn on and i believe this fully.

after a timing update - i am better
after a motor swap - i am better
after gordy bouche - i comprehend
after all of this - i still know nothing

vg30de motors are very durable... the weak point in both NA and TT is the pistons... NA boosted (around 400rwhp properly tuned) TT moded around 650rwhp... put some forged pistons in there and 800+rwhp is definitely doable! the engine wiring harness is an issue with corrosion, but only after about 10years of age. like some have said, lots more support aftermarket wise for the vg30de, but the vg30e is getting closer as we build more of them.

Hi,

I want to replace the 1300 engine in my mk1 escort,

My choices are between a Toyota Lexus V8 or the VG30DE,

What would you suggest should I do since this is my first project car,

Your advice will be much appreciated

Thanks

Rinus
