75 280Z 383 JTR Build Thread
Chasd posted a topic in S30 Series - 240z, 260z, 280zI have an old school JTR conversion i started ~15 years ago. (No LS's motor's back then!) After i put 1,000 miles on the car i transferred to Australia. You can see that effort here: http://aka.ms/chuckscar In the process of driving it to the storage facility the fuel line was pushed off the regulator spraying fuel on the headers and -well you get the idea instead of a Datsun going into storage i have a burn victim. Fast forward to today with a couple of mice playing house in the rear quarter panels for the last decade+ resulting in some slow cancer I am trying to figure out what to do w/ the car. So far i have changed the carb from the Edelbrock to a brand new Summit Racing/Holley 750cfm vacuum secondary carb, ran a fuel line to to plastic bottle w/ a hand pump, pulled the plugs gave it a shot of Oil in the cylinders, turned it over for a minute without the coil, put the spark plugs back in and started it -YEAH! At this point the plan is to strip it down, fix the rust, reshoot it and make it into a sunny day toy. My question is should i start a single build thread or post as i progress? Thanks Chuck
Chevy V8 Crate Choices?
Dlirium posted a topic in Gen I & II Chevy V8 Tech BoardHowdy All - just came into a nice 1972 240Z that currently has a Chevy 350 in it. Conversion already done, but I'd like to drop a few more HP into it. I have two questions - 1) I'm thinking a 383 with 450-500 hp would be a nice match. Since it is already setup for Chevy, i'll stay that route. What are some of the other options I should consider that are popular? 2) Engine source. There are a TON of engine builders on the internet. I know that many of them use junk Chinese parts and it will probably grenade quickly. Are there any reputable chevy engine builders that folks on the forum have had good luck with? Thanks for the help!!
Hi everyone, I've been using this site for research along the way gearing up for my build. I just created an account, and this is my 1st post. I'm excited to interact and share my experience as I go with those I've mooched off of for so long! I've done a trial fit to check that the motor/oil pan/trans all lines up ok- so far so good! I'm now in the process of the final build on my 383, and about to pull the trigger on my suspension/brakes/hubs/axles etc. I figured I'd give up some info for critique from the experts (that's you guys!). I think I've ironed out most of the kinks of the build in my head, but maybe someone can catch me before I make stupid and expensive mistakes. 1st, a little history on the car/theme- I moved to san diego 5 years ago from Philadelphia, and I never knew such fun roads could exist! So I decided I needed a car that was more fun to drive, and after test driving a lot of cars, I bought an rx8. This was not even on my list of potential vehicles, but the salesman offered a fun test drive, so I bit. After driving such a light car, I can vow to never have a heavy "fun car" again! The rx8 was a hoot, but it didn't scratch my hot rod itch. After some digging, I came across the z cars. Amazingly lightweight, awesome weight distribution, ample underhood room, ginormous transmission tunnel, manual rack and pinion, strut suspension- I'm so in!!! Ok, now all I need to do is find one, being from philly, I've barely ever seen one- salty roads and weather wiped them all away long before my time. I figured I'd save up, and find a good specimen even if it took months. It took a day...I found a clean 69k mile, 1 owner, original orange county car for $1300 an hour from home- done! Ever since I've been reading and researching for the proper combination of parts that will satiate my "requirements" as a driver. It needs to be fast- stupid fast. It needs to handle- and not make me wish I had something else. It needs to look great- which Z's do!. It needs to be affordable- I'm not a "rich guy". (I could have bought a restored 63 corvette with a 9000rpm 302 or something if I were rich!) In all honesty, I'm really happy about the path I'm headed down with this car, and it really seems like a no compromise plan for not "classic muscle car" money, and it will be faster, handle better, and in my opinion, even look better. I can't decide if I really liked the 240 that much off the bat, or if I fell in love with it after staring and dreaming...I think it was both! Ok enough blabbering about why I'm doing this, and onto the technicals- This will be a street/strip car. Street because it would be a sin to build a drag car with the roads in san diego. Strip because theres no point of a car (imo) that you can't let fly. So the plan is as follows, 383, 11:1, brodix track1 heads, solid roller cam, single plane, holley 850hp carb (I build engines, that's the easy part). Should be about 550 horse on motor and pull to 7200 rpm, coming in around 2300rpm, trying to make it a canyon carver and a strip terror is tough for a cam designer, but my man says he has it covered... T56 6spd trans with aluminum flywheel and Ram powergrip hd clutch, good to 650hp as per Ram, and thats for a 3600lb car. R200 from q45, with techno toy tuning backing plates allowing q45 hubs, eliminating stub axles and flanges, while using q45 cv's with chromoly axles, and q45 brakes. Techno toy coilovers all around with tokico illiminas, 5 lug front hubs, and 300mm 4 piston brake kit. MSA sway bar kit, and quick ratio bump steer spacers. Possibly "zpowersteering's" electric steering assist kit. I have a shop on board to do the roll bar. For wheels I'm thinking 16x8, 5x4.5, 0 offset American Racing Torq Thrust II's polished. For tires, 225/50r16 front and 245/50r16 rear, maybe 45 series, not sure on that yet, need to do some measuring. I'm planning to use vintage air's system for AC, because the last thing I want is to get the car done, and loathe driving it because I don't want to stick the the seat. Soooo, what do you guys think??? I'd like to call out rebekahsz on this one, she always seems to have good input on stuff I've read before, plus the front tires are off the ground in the signature thumbnail Sorry that was so long winded everybody, I guess I've never had a chance to say all that to anyone that I thought would care before... please feel free to tell me if I'm barking up the wrong tree with any of the parts I've chosen, or if you have any better ideas, all I have so far is the motor, transmission, and car. The techno toy order is ready, and I'll probably order it next week after I build the car in my head 10 more times haha. (Ps- the body isn't as bad as it looks, just red paint flaking to the original yellow beneath. I think that's why I got it so cheap, in the craigslist ad, it looked like bondo everywhere!) Thanks to all who have any input or recommendations in advance.
