nope, another, much larger nissan.

not a justy, but after the weather we recently had, my want for a justy has been increased. found a nice 4 door for $1500, and a 2 door for $500.

I think its the Fairlady Z(S30) with an SR20 in teh werks

Lighter engine, a large variety of modification possiblities not to mention much cheaper than z32 part prices, more room in engine bay after swap. Ehh...I would think about it.

I actually like the Pulsar idea. FWD SR20DET engines are cheaper to buy in that configuration.

How bad is the SR head design? The SR head is wider than the KA head (DOHC) so I would think it was engineered better for flow.

RB's were JDM only. (there's that fancy word again!)
they have different laws in Japan about engine size and taxes and such. The Fairlady Z originally had a 2000cc L20 while the US got the 2.4L
so they've always had slightly smaller displacement than us, but usually they had more turbo options than us.
They got the SR20DET while we got the KA24DE. whoopty doo....

oh ya, and on the SR20DET swap in a Z32... you can change your own oil without removing the engine!

i know they got diff laws but.... it still dont add up.....

and in japan is supra motor still not an I6 3.0 litre and a z32 a V6 3.0 motor... so why did they make the I6 RB a 2.6 litre... its just wierd... so i freaked out lol

Fairly Z

I've always wondered about this... The power difference between these motors. Personally, I wouldn't go near an SR20. They're good for modifications, if you're planning on rebuilding the engine, but otherwise, I just think the VG engine is simply better, from what I understand. You're making a comparison between a Z and a Silvia, and a Z is higher on the food chain. Now, if it's an RB series motor, then that's different... Those are always used in creating high horsepower monsters. Those, and the 2JZs as well. They're inline sixes. We see tons of these 1000 or 1500 horsepower Supras and Skylines, and point taken, they're absolutely insane. But, can the VG engine do the same thing if the same amount of love was put into it? That's something I've always wondered. The highest horsepower I've seen a Z32 at is 800 something. Not that I'd ever consider pushing my car above 600, it's just unnecessary. What I'm trying to ask here is this. Is the VG30, a V6, capable of the same amount of power as the 2JZ or RB inline sixes?

Well the SR has 4 cam lobes in each side and then a rocker arm to open both valves at the same time. thus requiring little shims and rocker arm guides that are very small and in many diferent sizes (32 diferent sizes i bleive in a 0.001mm diference) so yeah its a high reving motor, but the rocker arms tend to "float" or come off at high rpm's even with the rocker arm stopers once you get the after market cams, you need to go with solid Lifters, and other stuff among that.... (virtually elminating the need for a rocker arm) Unlinke every other nissan engine that has 1 lobe for every valve in the head.

this is what I mean here are some pics of my most recent blown SR

what was left of the 2nd cylinder rod bearing.

really... any motor is capable of being a power monster.. i see some sick skylines but i never see the RB motors being used as poewrmonsters. its always the 2jz becasue its this insanely strong all iron thick inline 6 turbo motor... the parts line is huge in america as well as japan.. and on the top power list its 2jz 4G63 and a twin turbo NSX motor... and i have searched threw and seen VG motors rated at 1200 hp actually. but if you ever go to nopi events and crap like that the drag cars almost always seem to be setup with 2jz motors. the reason they use inline sixes is not cuase they make more power. its because they can work on them easier and faster when **** does break and it always will. its easier to access every part on a motor thats a straight six and also you can fit one larger turbo on all six cylinders for better turbo efficiancy. also the mazda rotary engines can put down some sick numbers. on the strip


EDIT: oh yeah and VR4gasm... ever decide on a car and purchase or what? **** or get off the pot lol

actually, changing the oil on the z32 is really really rediculously easy. one of the easiest cars i have done it on. filter and drain plug are both readily accessable, and dont have things in the way that get dripped all over. hardest part is getting the car in the air. i have to drive on to 2x4s so i can get the floor jack under it.

hoov100

try jacking up a car thats been lowered 2.5" three 2x4's stacked in a "slope-like" style, just so i can scrap as i try and get my car on ramps designed for street cars..

snwbrderphat540

yeah i loved changin the oil in the Z32 also... easy as pie.... or is it cake?

hoov100

baking a pie is easier then a cake, so i guess its pie.

Bleach

If I can't see a wrench on the ground, reach down next to the engine and pick it up then there's not enough room.
Besides, we're talking turbo engines. Neither of you have a TT Z32. There's twice as many pipes running next to the engine with those.

You dont even need to jack the car up with an SR

snwbrderphat540

dude... changing the oil doesnt change from a TT to an NA... oil filters are in the same spot under the car with a whole cut in the plastic undercariage **** so you dont have to remove anything.. the drain plug also has an opening... its easy.... soooo.... what does ownin a TT have to do with changing the oil on a Z32 being easy as pie?

Bleach

jacking up the car and removing plastic covers? I don't even have to lift the hood on my 280ZX!

lol

snwbrderphat540

i said you dont have to... they are cut out by factory to have them opened up so you jack the car up and can easily just reach under grab oil filter and oil plug... yeesh.... the oil filter aint stickin out the side like in the L series motors they stick out straight towards the ground just like the oil plug on your car....

bardabe

you sir are wrong. I could have done 20 Z32 oil changes while only being able to do one in my SR. no questions asked, I speak from experience.

hoov100

what plastic thing?? i have never even seen a z32 with a plastic cover.

emo236

he means the bottom engine cover.

entropy31

i dont have to take anything off to access my drain plug or oil filter.

Bleach

lucky you. well there's the one thing thats easy to do on a VG.

bardabe

LOL brakes are the next easiest thing. after that it's all "damn I have to remove A,B,C and possibly D to get to what I want" picked up the Race Bread last night. =]

Bleach

I want that!!!!!

snwbrderphat540

that would look hot in a 260Z... what are you doing with that now? the s13? and is it a 26 of a 25???? stupid intake going over the head... lol
