i see the R200 is bigger in the picture (across wise) then the R180.
do you know how much bigger from side to side the R200 is then the R180?
if so i could measure it and that would tell me my answer.

snwbrderphat540

i was kidding shady i can tell. lol

michanic im pretty sure you have a R200 i thnk an easy way to tell is if it uses half shafts or CV shafts right guys? the R180 never used CV shafts if i remember even though i know the R200 originally used half shafts lol.

lww

Snw... I have no idea what you just said.

Anyway, the '81 to '83 NA Automatics all came with a 3.545:1 R180.

The '81 to '83 Turbo all came with "pseudo" cv axles and a 3.545:1 R200

The '81 to '83 MT NA came with a 3.9:1 R200.

The '81 to '83 2+2 NA MT cars came with "pseudo" cv axles and a 3.9:1 R200.

more like no replacement for a heavy *** iron block!!!

but a 350 might be good smaller lighter and seems to make more HP per Lb.(not compared to l28)

but if light weight and hp are your thing.... go rotor

michanic220

i like the 350 because its capable of alot more hp the the L28E. being that i dont want to turbo charge it. turbo's are great and all but somthing spooling at 80,000 RPM is just somthing waiting to happen. buddy blew up his engine because his turbo flew apart, oil from the turbo went into the engine.. oil doesnt combust and it blew his head gasket. luckly he didnt get a hole in the piston or destroy the block.. but i've seen that happen too. anyways like i said im looking for a engine to build up over the years and a L28E N/A from what i read from here is only 300hp capable. and i've seen 350's bored .030 over with a stroker crank (383 stroker) cranking out nearly 1000 hp.

I have to say that is quite a naive comment. So all turbo Porsche, Ferrari, F1 race cars, Z's, PT Cruisers, Eclipses, Evos, WRXs, Saabs, Diesel trucks, (you get the point) are waiting to blow? Hum... I don't know why turbochargers are still made today if they all blow.

FYI... it's up to the driver to take care of the turbo. Tell that to your friend. And homemade setups (when designed incorrectly) will obviously have a higher chance of destruction, than a tested / proven mechanical engineer's design.

snwbrderphat540

yeah turbo's dont usually catastrophically fail like that unless the owner beats the **** out of it (like alot of compressor surge and 2-stepping it where theres an abnormal amount of combustion flowing through it) and doesnt monitor the health of it. also you can still make tons of HP and still get good gas mileage on turbo motor because they dont create boost when at a cruising speed so there much less need for fuel flow where in big HP NA motors the compression is so high there much more need to keep the mixture right at all engine speeds. however a light high HP V8 will always be cool... but only to a point because all the torque can make traction pretty much impossible to keep in the first 2-3 gears.

michanic220

i dont mean that they will, im just saying i dont trust them. lol.
and he took care of his turbo, his 500 hp eclipse (ricer) lol.
and it blew apart at cruising speeds.. must have just had a compressor wheel
offbalance or somthing. or not getting oil. anyways you both make a good point.
i just dont trust them.

NismoPick

Meh... it's your loss.

SHADY280

usually its the ebay turbos that blow, i dont even think they torque the bolts on them. dont forget, to make power in an n/a, you need high compression, if youve ever seen or heard an engine detonate and let go becasue it burped, youll see that they arent fool proof either. the holes in the piston, or melted rings are impressive when displayed on a wall tho

michanic220

lol, yea..i should have my V8 the day after tomorrow.
putting a automatic transmission in it for now (th400)
because i wanna get it on the road and dont have the $$ for clutch master cylinder and other stuff to get a stick in it.
i think im just going to go with headers and a agressive cam for now, then down the road get in to internal engine mods.
not sure if i wanna supercharge it. or go with high compression..
leaning more toward the super tho.
i think V8's shouldnt be single turbo'd. only dual.. not saying that it wouldnt work really good. im just that type of person that has to have everything on the left side the same as it is on the right.
altho a twin turbo 383 would be pretty sweet.

there suposed to be coming out with a new "foil bearing" turbo or somthing, doesnt need any kind of cooling. i see a heat problem there but who knows.

Every time someone shoves a Chevy motor into a Z Car...



God kills a Kitten.

NismoPick

^^^ Buahahhah! Where you been Rod?

michanic220

got the new engine, well new to me. getting the TH400 tranny next week. the engine had a lil water in it but has about 130PSI on each cylinder.
just updating on here. ill probly start posting on hybridZ because they have a V8 forum and everyone here likes stock Z cars? why? you have to make the car your car in my oppenion. anyways, pictures will be up to date on cardomain. link should be in sig bar. -jt.

lifegrddude

Good luck with the swap, are you going to rebuild it on a stand, or change the headgasket and swap it in? Just a heads up, watch your caps and punctuation on HBZ, they are real strict with that. And yes all of us here like stock Z cars; all the modifications we do are fake and not really there. David Copperfield eat your heart out.

NismoPick

Indeed... ARP head studs, MLS head gaskets, Big turbochargers, ECU upgrades, 300hp... All stock Z cars baby!!!

snwbrderphat540

^^^^^ hells yeah nissan oem factory shiznit talk about ahead of their times lol


also only 130 psi? thats crappy... well to my standards maybe not an american V8 lol. thats a big heavy motor though that z is going to handle like poop! so to redeem yourself you should rebuild for a much higher compression ratio larger cam and carb's and spark system and get some decent HP for a not so big $$$$$ amount. otherwise i hope you have a fun future in towing cars with your Z


also. Rod... hot rod... w/e im the only true SP fan here. i was at there fairwell concert and hopefully at their first chicago stop since they have been back together... well.. "together" seeing as its chamberlin corgan and 2 no namers lol.

SHADY280

hes so gonna get banned from hybridz.

michanic220

i havent been banned from hybrid Z yet.
and me tow away cars? when i get it done it will probly be faster then your stock Z? lol. the V8 weighs just as much. probly a little less with aluminum heads and intake then the L28. and my 350 is pushing 250HP and 350 pounds or torque stock, what the L series hits all tricked out? isnt there a problem there? LOL. btw, read up on james watts quotes. horse power is nothing but the humans way of understanding the power of somthing. torque is what turns the wheels.

snwbrderphat540

i will bet you 1k that it wont be faster than my stock Z... now we are all agreeing that all im stating is stock, and Z. right. no other stipulations here



ALSO! you said a 454 not a 350 and the Z engine is not very heavy idk why everyone claims they are so heavy they really arent. and most stock V8s from the 80's that ive seen barely make 195hp lol. its kinda ridiculous. also HP is a measurement its a torque to engine revolutions figure. torque only really matters when an engine is moving slow. its not everything not by any means and i want to just punch some one square in the face every time i hear that.

NismoPick

Looks like you're on your way though ( http://forums.hybridz.org/showthread.php?t=138389 )

They don't tolerate much of the "I dunno if I have LSD, but I'm going to be pushing 500hp!" mentality.

PS... you don't have LSD. None of the 280zx's came w/ LSD, only the 87-89 Z31T came w/ one.

NismoPick

The L28 has an aluminum head too, has 2 cyl less than a V8, and also has an aluminum intake. So arguing that a V8 is lighter than an L28 because it has aluminum heads and intake would actually prove it HEAVIER.

I'm not saying which is actually lighter... but your argument has no factual base.

lww

The L series blocks are pretty damn heavy given their displacement. With aluminum heads and intake manifold, the SBC is still about 80 lbs heavier. The LT1 is slightly lighter but the LSx series Chevy motors are pretty close to the same weight as the L series and are why they are now the preferred Chevy/Z car swap. The aluminum block, heads and intake manifolds make them pretty light given their displacement and power potential.

michanic220

like i said on here 1,000 or more times. im not on here to claim i know everything like you guys, just to learn. hint hint why i ask so manny questions. the 350 small block has way more patential then the L series. it can put out numbers that a supercharged/turbocharged L series engine can and probly more without being super or turbo'd. then adding a supercharger or turbo charger gives you all that much more HP.
and look at it this way, the L series is what? about a foot longer block then the 350 small block? thats the whole block from top to bottom of the L series vs only the top V and two extra pistons of the 350. so i can see where they are very close in weight. and there going to ban me from asking questions and trying to learn somthing new? wow, if they ban me.. no biggy why would i wanna be on a site that bans someone that doesnt know anything about japanese cars?

michanic220

bearly make 195 HP idk where your from? all the 350's around here are pushing ATLEAST 250. check this out tho. go to google. type in 10066036
and press enter. look at the HP and torque specs. theres the end of a argument that hasnt even started yet. says 350torque on quadrajet 4 barrel carb, elderbrock performer intake, and 1 and 5/8 headers i beleive it was? which i have all the above besides the headers but i have hugger headers in the mail.
