is it the same concept as a b18 and a b16 "honda wise"

 

It's the same concept it's always been...

"There is no replacement for displacement."

 

Well I don't know why you'd particularly want to go turbo, especially with a VG30. You would just make that engine bay a pain in the *** to even look at. You can essentially get more power out of a single turbo, but a twin turbo setup is better for quicker boost from the getgo. I don't believe it's incredibly hard to TT a VG30, but it's not easy. I agree with what everyone else says. If you've got $20k to throw at this car drop it at a shop and have them do it. It will be more expensive that way, but you can bet it'll be in there and you won't have to worry about doing it yourself.

By the way, got any pics of the Z31 you've acquired?

 

it's all about displacement. vg33= 3.3L, vg34=3.4L. more displacement=more power potential.

 

Ahhh yes, but as the great Billy Crystal once said... "It is better to look good, than to feel good"

the pics will be up in about 24-36 hours the car is on a truck on the way down here to new hampshire it is leaving tomorrow morning so as soon as i get it i will have pics on here for you guys when i get the new powerplant is there a forum to sell my stock one on or should i keep it. i think i am gonna take you guys advise and have a shop do it but i feel cheap knowing that someone else did the work it's a whole pride thing with me i have built every one of my other cars . i'll get over it tho i guess. thanks for your help and thanks az for that link i just found my new car bible lol.

 

swap in a Gallo 12.

 

oh one more thing where can i get a couple different body kit choices something up to date yet none of that honda b.s. i'd almost like to go japan style body kits

 

In all seriousness, if I had that kind of budget to work with I would send it to someone with the skills and do a built motor swap. It's nice to say you did the work yourself, but it's even better to know it was done correctly and to its full potential. A VG30DETT wouldn't be a bad idea except for the fact that they are a beeyotch to work on. AZ-ZBum's VG33 idea is a good one too. Maybe you could find an Eaton S/C'ed one from a wrecked Frontier... That would be sweet and different from what anyone else is doing. What ever you decide, I know that once you drive it... You'll be a lifelong Z car guy. Welcome to the fraternity

thanks nice to be here lol

 

naw... Gallo 24!


Am I the only one that got that?

 

i never new pizza shops made motors lol rofl

 

hum... that Paul Walker.... He's so hot right now!

 

lol where can i get some j spec body styling

 

No no no... It's "Ernest and Julio Gallo" the fine wine makers...

I met a guy at work the other day who had a cashiers check in his name from Patelco Credit Union for $150k...

 

RB would be a great swap for a Z31. The swap is relatively simple on that car. An RB25 is PRACTICALLY a bolt in deal. You get the greatness of turbo power in the awesome platform of the RB all while clearing up a little elbow room on atleast one side of the engine. I didnt read if anyone cleared up the "whats an RB" question or not but just run a google search for RB26DETT or RB25DET or even NISSAN SKYLINE and you'll find tons of info. Now take your car, that engine, and all the parts neccessary to a shop with $20G's in hand and you will walk out one happy camper (well once the car is finished anyways). If you've got the means and know how then you can do the swap yourself and save a few bucks to put toward other areas of the car. Get some suspension parts put in to keep up with the engine

Oh, and just for the record: If I had $20K, I'd keep my S130 AND get a Z32 TT I mean if I make that kind of money I can affford both. Then I'd keep the Z32 stock and work on the S130 with the left over money from the Z32 while using the Z32 for my daily driver. But thats just me. I mean, I know the S130 will NEVER be the car that the Z32 can be so why try But atleast that way I'd have the best of both worlds. Classic sexy looks and modern death trap speed

 

^ Heh... I keep the S130 because the Z32 scares me as a potential daily driver. AAA only gives you so many free tows every year ya know...

once again, my site provides the information you're looking for...

http://www.az-zbum.com/information.body.kits.shtml

 

Why do you believe 3 cylinders will spool 1 turbo faster than 6 cylinders will spool
1 turbo?
Twins are about packaging,not spool.
However sequential turbos are designed for quick spool,but they do not apply here.

 

I suggest you do alot of research before you decide anything.
AZ-Bum has a very good site.
This is another very good site http://www.redz31.com/

Read both of those sites and folow the links in them.
There is alot of good info out there.

 

Build it yorself.You will save alot of money,and have the pride that comes along with it.
There aren't many shops that know these cars anyways.And on top of that there
isn't hardly any aftermarket support for our cars.
Forget about Nissmo.
Most off the aftermarket parts for these cars are built by guys who own a z31.
With your research you will find these parts,or get ideas on how to make your own.
If you know how to weld the sky is the limit.
Good luck.

 

twin turbos use 2 smaller turbos. smaller turbos spool faster than big turbos, but with 2 of them, you can get boost equivilant of one large, slow to spool turbo.

sequentials use 1 small turbo for initial boost, and 1 larger turbo for top end.

either way, you are getting faster spool times than you would wit one big turbo.

 

On the same size engine, of course you would. But you're missing the point. You're now comparing two 1.5L engines each running a small turbo to one bigger 3.0L engine running a bigger turbo, there are more variables.

 

Twin turbo's are about efficiency. Will 3 cylinders off the same motor spool a small turbo faster than 6 will do a slightly larger one? No. However if each turbo has to do less work then each turbo is going to be more efficient then if you used only one turbo. Twin turbos dont eliminate lag compared to a single set up unless the two smaller turbo's are so impractically small that you lose all efficiency at the top end or you're using a single turbo thats too large for a "street' application. Which is where one would be concerned with lag.

Twin turbos are meant to preserve driveability AND keep the top end. Thats efficiency. And that applies to sequential and non sequintial setups as well.

On a V6 the twin turbo makes a little more sense as you can place the turbo's right near the exhaust ports where they'll be most efficient. Where as with a single turbo setup you're going to have exhaust piping routing exhaust gases to the turbine which decreases some of that efficiency.

And on top of all that, turbos arent light. And if lag is your concern then top end ISN'T and weight really becomes a factor.
