rb26dett vs vg30dett

[usdm240sx]

Im new to NICO, but have alway been a fan of NissanI know that the rb26dett is the hottes motor, but i have been reading about people dropping the vg30dett into the 240 vs the rb26dett. is this just a cost issue or is the vg30dett comperable motor to the rb26dett.

no

[the_momo]

not even remotely. the only similarities between the two are1. six cylinders2. two turbos3. strong transmissions4.strong aftermarket support

thats it. the vg is FAAAAARRRRRR more complex than the rb. (thats in my experience, i have not worked ona rb26, but rb motors are fundamentally the same. i have an rb20. i have worked on both tt and na vg's i hate them, i hate them a lot)

that being said. both are expensive. both require custom wiring and fab to work in an s chassis as the car wasnt ever offered with either motor.

if you can spend the money, do the rb26. if you want an "easier" fast car, do an sr20. easiest swap into the s chassis. or turbo the ka. you have a lot of choices, 2 of them you are curious about, but they happen to probably be the most labor intensive and expensive of all logical swaps to do.

i have a sbc in a s13 and a rb20 in an s14. neither was cheap or easy to do or work on. but it can be done if you have 1.time2.money3-1thousand. patience

good luck! and welcome to nico!

VG is complicated, that timing belt is longer than the us/mexico border. Double everything on the valvetrain too. RB needs two cams, VG four, that goes for the pulleys too. Instead of having one head done, it's two and my local machine shop don't charge by cylinder count either, they charge per head. Everything is a pain EXCEPT for the fact that the VG is a US market available motor. I don't hear VG owners scrambling for grey market parts just to get running.

lock this thread

I will lock it if it needs to be locked, it doesn't. You are pretty light in the post count to be issuing orders.

Buuuurn!!!

I think the big reason you are starting to see the VG's show up is price. You can get one for less than and RB25, and in some cases at almost RB20 prices. You can get all the parts you need in the US also, so you don't have to order parts like you do with some RB stuff.

Just get an SR20 and you will be having to much fun to care that it isn't a 6 cyl.

i talked to some local shops and they do not like to work on the vg30, but also the have not had a chance to work with the rb motor. Thanks for the info

PS: what is locking the thread?

I personally like to use thread lock on my flywheel bolts

I have an RB26, therefore I give the orders.

it makes little difference that the vg is a usdm motor. the parts are still waaay to expensive. and like has been said, times two. talk about insult to injury.

my exgf's dad had a "small" collection of z32's. one had a bad hg (left bank) he asked if i could do the work. i said sure. quoted him 1500 plus parts. and thats with the "im doing your daughter"discount.

seriously buy a sr. that probably has a larger parts avaliability in the us than the vg by now. and the parts are poor college kid affordable.

I have an RB20, three RB25s, an RD28, two CA18s, a CA20, two L20s, two L28 strokers and Two FJ20s and I almost forgot "moderator" under my name,so, I give the orders chum love and kisses

[themadscientist]

So what are the high-power VGs putting down in the states. I see very few people seriously working them over here, about 600hp is the best I have seen. My main complaint with them is the complexity, the "one more thing to break" worry.

a guy by the name of chin in the detroit area had a Z32 that made roughly 835whp WITHOUT nitrous. i cant imagine the sort of coin that was put into that thing... he ran mid 10's and trapped in the upper 140mph range. great looking car IMO, and i would LOVE to have one. but i dont have the cash to keep up on maintanence AND mod it. let alone the patience. ive not worked on one, but just looking at that VG stuffed in there is enough to scare most people away i think.

[themadscientist]

The VQ in the Z33 looks like a bastard to get to as well.

[jrb92se]

the noob doesnt give orders, rb26 or not, that said there is also very little room to work under the hood of a 240 with a v6

[usdm240sx]

[the_momo]

are you talking about the silver one that came to xceed every once in a while? i dont know for sure.

there are a few z's that put down big power. but i persoanlly havent seen any that i am for certain were over 500whp. just doesnt have the appeal to many i guess. id personally never own one after having (see:forced) to work on one. just not something that i could see enjoying. and personally, i dont really like the way the z32 motor looks. im a sucker for an easily visible turbo (or turbos)

[Kansei240sx]

Theres a guy here in town in the 800-900 rwhp range depending on the fuel he uses, most of the time its methanol so its towards 900 in his Z32. Its wicked sick. At 4th gear going 100 mph, it goes and hits full boost and spins the wheels till 120 and then hit its at 160 like crazy in no time at all.

I like to do my own work, but when it came time to replace the injectors in my 300TT, I took it to a shop. Way more work than I wanted to get into. it ended up costing me $1200 for 6 injectors because of the labor costs. You have to remove the whole intake plenum and whatever else. Very time consuming. When I replaced the ones in my RB25, I did it myself and it only took about an hour and a half.
