Thread: I can haz VE? Yes I can!

Nemu board shipped this after noon.
will self install nemu...with write up.
Took off old VE engine harness to prep for swap with the DE harness.
bought a N62 maf with pigtail.. will have to reprogramm the nemu board for it but for now I am not going to install it right away.. need to get the motor in before i do anything else.


would the GSpec water pump pulley and crank pulley be worth the money? Will be selling my DE UR pulley set... all four Crank, A/C, P/S, W/P soon.


going to need a intake for the VE. Might get a buddy to make one up for me.
Would be selling the Highport DE intake I have currently after I get a good VE intake.

Thats all that is happening currently will update when I have more stuff that I bought and start installing the motor.

Make sure you get yourself a good soldering iron and desoldering iron. Mine was a little too cheap ($15 one) and had to resolder some points because they came loose from driving.

What injectors are you running? I can help you with a base tune



I would pass on the crank pulley, one reason is VE's are 4cw and are high reving engines. My engine didn't like a crank pulley at RPM's above 7200. Logs show loss of power and felt like it was dying.

Water Pump pulley is a must though, I left my GSpec WP pulley in there especially when your reving above 7500 rpm.



You can always get away with a $50 ebay low port one too . I personally will make mine out of stainless and heat wrap it.

Definitely stay with a VE water pump, it should be similar to Roller Rocker one. They are redesigned to have less cavitation at higher rpm's. Using a bigger pulley like the UR or Gspec one should help more too.

What RPM's are you planning on hitting? My Power steering high pressure hose recently bursted from just about daily 8300 rpm reving.

iron is not a problem. have access to good ones both through the dealership and ones and my high school in the tech department.. infact i repaired a wireless card by solder on a new path... actually worked so that started off my fun in this lol

stock VE injectors unless i have a reason to have to get higher cc ones. also, the N62 maf was available at the right price and so i got it. i was told it was over kill but that is ok in my opinion i dont care lol beside if i decide to do something major like turbo i could use it possibly or something.


ok, i will order the water pump pulley today then. i do have the water pump pulley from my DE UR pulley set up, that should work correct?
also, i matched the parts from the VE to the DE water pumps using the Fast system.. i have the Japanese one at home.



ah, didnt know that. i wasnt sure how many lines go to the piece so i wasnt sure it would work. but thats ok, i dont mind making one either. heat wrap it.. will do that.. also goin to heat wrap headers as i didnt do that with the de.

I believe i covered everything.. at work and starving so i hope i am thinking clearly enough... vadim, would greatly appreciate help with a base tune.. I did have John load one before he mailed it but its going to have to change now

its a DD, well it was till I started car pooling with my dad to work, so it will be a fun car and a trip car.. so around town driving peaking at maybe 6k revs and also depends on how much fun i want to have.

From what I'm seeing on G20.net, and replied to my thread, our power steering hoses just suck, inspect it etc. It's easier to fix while engine is out .

N62 maf is quite a bit of an overkill honestly. I'm running it NA right now, but I will be turbo again eventually. You have a lot less down low resolution because it needs to read to 500whp. You should be able to tune it out though.

UR DE water pump pulley would work, but Gspec ones are bigger (but it's not a must if you don't rev high often). If you decide to use your UR WP pulley, and not sell it as a set I'll pick up your power steepening pulley

What base tune did John put on it? His basic tune might be better then what I have

If it is more work to tune it out I will try to do. I have to learn that process anyway.

I'll probably use stock WP pulley till i decide where I want to go, wont rev high often anyway gas prices expensive.

N62- so max rated HP for this is 500? im not following what you mean. I would of gotten a N60 but none were around the normal $65 range. mostly around $85-100 plus shipping.. so i opted for this one.

john tuned it for these specs:
stock VE with stock injectors
impul headers and downpipe
stock DE mafs
stock cat
3" cat back
and thats it.
also got him to engage the VVL intake at 4600 and the exhaust at 4800.. to start off with and i will adjust from there.

Might as well stick with an RR if your not gonna rev high. VE makes it's power way later in the power band then an RR does. So if you don't rev it out you can actually be slower then stock RR. Now that it's colder my VE does feel torquer then my other P11 with an RR. But tune has a lot to do with it too.



N60 maf is from 91-94 Maxima's
N62 MAF is from 91-96 twin turbo 300zx's.

It's funny that an N62 maf would be cheaper, someone is smoking the reefer and got them mixed up . Though I did recently purchase another N62 for the same price that you did. Usually they are going for $100.

It's generally not a good idea to go overboard on MAF, simply because you loose daily driving resolution when you do. Even turbo E60 and Pathfinder/VE maf good for most applications since it maxes at 325 whp. But I wouldn't sweat it too much. I personally saw the same gas mileage numbers between the E60 and N62 maf.



That's a very good base, all you will need to do is use the MAF changer from NismoTronic. It should take care of the K value, and TP scales for you. Once you get proper AFR's it should be fairly easy going from there.

Ok, i will stick with VE WP pulley untill i start tracking the car more often.
I'm not worried about the PS hose currently so i will deal with it when the time comes and since i wont be revving all that high all that often it should last a while.

Thanks for the MAF info. If I happen to come upon a N60 or E60 I will switch if it is a good price. For now, like you said, I can make due with the N62.
Who knows maybe I can squeeze out 500hp lol not. at least on my cheap budget.

If you want I can send that tune over to you so you have a good base tune. And glad to know there is a MAF changer option that changes everything for me. makes my headache less big.
------------------------
On another note, is there anything else I should get?
fuel pressure adjustments or anything like that? or stuff i can do with out until i can get it in the future

I wouldn't worry about the maf too much either. I am tempted to give the Pathfinder maf a try (since E60's have been treating me dirty). But don't want to spend the money since I'll be going to MAP as soon as TunerCode V6 is out.

Keep in mind you will have to make adjustments to the fuel K value and scales still. Do you have a wideband or are you going to hit up a dyno?

No worries on the base tune if anything I'll ask John for it .

An adjustable FPR is not a must, you have plenty of head room with 333cc injectors while you are NA. Plus it's still cheaper to get 370cc injectors then an adjustable FPR.

I would definitely look into getting a wideband if your going to be touching the tune outside of the dyno though.
