Guest Anonymous Posted April 2, 2002 Share Posted April 2, 2002 Well, for those of you who don't remember, I'm the fellow who was going to build a v8 Z, but instead bought a 79 corvette... Well, I've gotten the vette running good (355 with sportsman II 64cc heads, flattop hyperutectic pistons, edelbrock performer intake, ect, with a 350 autp tranny), but I let my grandpop borrow my 85 300zx (really nice, I just rebuilt the motor last june and converted to turbo (PITA!). The five speed tranny had been overhauled two years ago...The car was running sweet and had had many performance mods. Anyway, I leant it to him saturday, and he brought it back sunday... three quarts of oil low...The turbo is now blown, the engine is tapping very loudly, it smokes like a freight train, and is basically shrecked up. This car had been my secondary car that I used for trips, but it is now defunct. I have tracked down a wrecked 95 camaro with the t56 tranny...I can get it for 700 dollars... I had origionally planned to get it, install the t56 in my vette, and sell the motor to recoup some of the costs. Now I find myself thinking that it may be a good idea to leave the vette's tranny alone (except for a shift kit and lock up converter) and get the camaro drive train and install it in my 300zx. Or I could put the t56 in my vette and the automatic in the 300zx, or I could put a muncie four speed in the 300zx... Or I could do as I had origionally planned and just trash the Z car. What do yall reckon I should do? Does anybody know how much an 85 300zx weighs? Anybody know how much power the camaro engine puts out? Will standard block hugger headers work with the camaro engine? What it comes down to is, will the 300zx benefit more in performance than the vette with the t56 (The vette has 3.08 rear end and puts out about 400hp at the flywheel, btw) than were I to install in it a four speed in the Z. BTW, the 300zx already has a four row radiator with some huge electronic cooling fans, so I should be able to use the cooling system already in it. The 300zx uses the same tranny as the 280zx, so the shifter position should be right. It has the r200 differential, but I'd need to get the ring and pinion from an earlier car in order to use the JTR adapter for the chevy U-joint. Sorry for my long-windedness.... Maybe I should just scrap the Z... All it now has going for it is the decent body and the new suspension and rack and pinion. Besides, It'll be a PITA to hook up the power steering pump on the chevy motor..unless somebody knows how to put a chevy pump on the nissan rack&pinion.

Guest greimann Posted April 2, 2002 Share Posted April 2, 2002 ....... It'll be a PITA to hook up the power steering pump on the chevy motor..unless somebody knows how to put a chevy pump on the nissan rack&pinion. I am using the box type power steering adapted to the GM saginaw pump. On the pressure side of the pump I used a Russell inverted flare to a -6 37 degree AN adapter. The inverted flare size is 5/8-18. Jegs sells this under part number 799-640381. Note that in the Jegs catalog the fitting I quote is listed as a 5/8-20 this is a typo. The web site is correct. For the hose assemblies I am using cad plated steel hydraulic fittings and hose that meet SAE 100R5 specification. I got the fittings from Grainger #2F515 for the straight and #2F281 for the 90 degree bend coming out of the pump. The hose I got from MSC industrial supply, #49728785. For the the connection to the ZX steering box I used steel -6 X 3/8" pipe AN adapters brazed to the stock banjo fittings. MSC #09105404.

tsumner Posted April 2, 2002 Share Posted April 2, 2002 Hi Jack, Have you looked around for a running 300z motor to replace the bad one? That might be the easy (and Cheep) way to get it back on the road. Tom Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted April 2, 2002 Share Posted April 2, 2002 ?????? why don,t you just hand grand dad a bill for the engine/turbo he destroyed by not checking the oil, if he had done that to avis or hertz do you think they would just eat the rebuild costs???????? ?????how much do you want for that (300-Z) (as is)???? If your going to rebuild that 300-z with the chevy engine swap, don,t waste time and money on a 305, sell the 305 add a few bucks and start with a 350 salvage yard 4" bore block, parts are cheaper, power is way better,and you can build a 383 that will make that 300-z kick butt!

Guest Anonymous Posted April 2, 2002 Share Posted April 2, 2002 Do 95 Camaros with six speeds have 305s? I thought that they had larger, somewhat desirable motors? Quote Link to comment Share on other sites More sharing options...
Guest Thurem Posted April 2, 2002 Share Posted April 2, 2002 Jack The thing I don't get is, how could your car get down 3 Q of oil in one day, or even a week? When was the last time you checked it? As a motorcycle mechanic the story, I hear, is always the same,with their finger up their nose, they say:"Yeah, I let my friend borrow it, and now it is thrashed/crashed/fu(?ed up" I'm not trying to point the finger at you, but maybe there was something else going on in your motor that your grandpop had no way of knowing about or even anticipate. As an example, my 260z with a ragged out motor that leaks like a sieve, and leaves a big mark whereever I leave it and smokes like a bitch. Takes about a week and a half + a tankfull of gas to get 3 Q low. Yet refuses to break. Thure Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted April 2, 2002 Share Posted April 2, 2002 He blew the turbo while he was driving it. If you are not familiar with the effects of a blown turbo, allow me to explain. The seal that keeps the oil in the cooling chambers and not entering the intake/exhaust turbines blows out, allowing a constant pressurized oil leak directly into both the intake and the exhaust... in which case it could very easily run through a few quarts. About half a quart went out the tailpipe in the ten minutes I had it running at idle while assessing the damage. I found out how the turbo blew. Sombody had put duct tape on the pressure blow off valve and disconnected and plugged the vacume line to the wastgate solenoid. IE: they had jury-rigged it to keep building boost past the saftey limits put in place by the wastegate. Grandpop, being the old drag racer that he is, had attempted to get me to do this beforehand to improve performance, and I had told him no. Apparently, he was trying to prove himself right. Well, it cost me a motor, and I can't exactly ask him to pay for it since he is, afterall, my grandpop. Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted April 2, 2002 Share Posted April 2, 2002 Im quite familiar with turbo boosted engines,I have built several. "He blew the turbo while he was driving it.....Grandpop, being the old drag racer that he is, had attempted to get me to do this beforehand to improve performance, and I had told him no.

I understand your problem......but he should at least pay for the parts, afterall its highly unlikely the engine would have blown without his RIGGING IT Quote Link to comment Share on other sites More sharing options...
utvolman99 Posted April 2, 2002 Share Posted April 2, 2002 It would not be a 305 it would be a LT1 350. Very good engine and trans combo. Quote Link to comment Share on other sites More sharing options...
Guest Thurem Posted April 2, 2002 Share Posted April 2, 2002 Jack That makes way more sense when you put like that. And I agree with the other members who think you should make him pay for the damages. That's malicious tampering with your motor.
