    280zx Turbo V8

    in Gen I & II Chevy V8 Tech Board

    Posted

    Here are some more pictures.

     

    Thanks for posting the extra photos; much appreciated. It always helps to see what others have done in order to perfect our own systems. I like this car more than beer, really :2thumbs: The car is so totally functional and it gives me a knot in my stomach to finish my own car :sour: It's only been 10 flippin' years. At least I did get into the garage today to do some work, so I'm not totally mad :icon56:

    V8 vagueness: to 383 on the cheap or not...

    in Gen I & II Chevy V8 Tech Board

    A 350 with a good set of heads will run better than a 383 with stock heads. So spend the money on heads first, then on stroke.

     

    I agree...

     

    Here is what I have in parts to add: Edelbrock RPM heads with roller rockers (I have 2 sets of aluminum ones and one set of steel rollers). The heads are 62 cc heads which would bump the compression from 8.5:1 to what I believe 10.1:1! I'm guessing on the compression ratio increase, but I think I'm close...

     

    I already have some decent heads; they may not be the all out best, but for the price I bought these baby's for, NO ONE would have walked away from them ;) . I agree about the balancing issues in a 383, but please understand that an internally balanced crank is the same price on ebay as an externally balanced one. There is no way I would build an externally balanced 383 for a 240Z, when I know that an 8" damper won't fit. I have a nice properly fitting Fluidamper that I'm dying to use when the time comes; also bought that cheap at someone's "fire sale."

    Second run- I tried to hold more boost but it pushed me through the lights and tripped the timer so the times aren't too acurate but mph is good. I figure it to be a low 9.90 or high 9.80. The front wheels seen daylight :).

     

    60' 1.73

    1/8 6.54

    1/8mph 113.01

    1/4 10.01

    1/4 mph 140.52

     

    PUMP GAS

     

    This is just silly sick fast. :eek2: All on a blow through turbo too. I'm amazed at what you have been able to wring out of this ZX. It warms the heart :D

     

    Great job on getting this car dialed in so quickly. I'm amazed at the progress and the times! :2thumbs:

    Doing the Jimmy Durante on the hood

    I agree. Taller in the rear, and ending at that line. Maybe even put a raised edge like you have on the hood vent.

     

    This is correct--the cowl will follow the lines of the hood and look more like it is supposed to be there. Higher and open in back. You sure are making progress, Terry. It's coming together for sure.

    Wanted Any Sacramento Z Owner!

    in Non Tech Board

    Posted

    That car looks super straight and there appears to be virtually no rust issues. As long as the title is clear, that's a great deal. The shipping prices you got were good. I paid $1200 or $1300 to get my Z here to NC from CA. Considering the price of fuel, you're doing well. Seller has excellent feedback, so I would not be too worried.

     

    Anyone in Sacratomato that can help him?

    If you have E85 available in your area, that might be a good path to go down. The fuel system would have to be upgraded, but what I have read on the octane rating of E85, somewhere in the range of 100-105, gives lots of opportunity. Higher compression n/a or a nice turbo setup, good to go either way.

     

    That's the one thing that keeps my interest on a relatively high compression turbo set up. I have an E-85 station about 10 miles from my house, so it is attainable. A road trip might be out of the question, but hey, I'm willing to try it :D I wanted to run aluminum fuel lines, etc, but I'll have to change my thinking if I go the E-85 route. It's not that it can't be done, it's just a little harder and more expensive to do (which means I can't do it yet).

    If you buy a 383 crank, you will need pistons to match. You could use the same rods.

    That would pretty much decide it then. I just don't want to keep spending on what amounts to a half-build in my opinion. If I have to do pistons too, then I might as well do rods, etc, for a proper build. I can't (and shouldn't) do that yet at this stage.

     

    I would build the 350. A 383 is a great motor' date=' but a nice 350 in a Z can be pretty much a terror. I'll be glad to help out if needed. When you get it running, bring it down to CMP and I'll help you get it sorted out.

    Wow, that's an offer I just can't refuse! THANK YOU! I'm still getting the engine compartment set to do the conversion and the idea is to paint it first, etc, then stab in the motor. I'll certainly take you up on your offer, belated of course.

    That is the thing I'm talking about. The question is whether or not to do it. I know the stoker crank will increase torque and hp, but it changes some things for me and I'm trying to make sense of it all... *head hurts*

     

    The simplest thing to do is to retain the 350 with the Edelbrock heads, don't turbo it and run it like that.

     

    If time & money were no object and I was staying with the Gen I motors, I would build a low compression 383 with forged parts, H-beam rods, the works and then turbo the sucker. That would be fun, but I have the parts I have to work with and not much more. I want to avoid any more large cash outlays as possible.

    Just poking around for some ideas. I have a bunch of parts and I'm deciding what to do with them. I'll put this out there for y'all in Z land to ponder and reply...

     

    OK, so I have this 350 SBC sitting in my garage, looking mournful as prep the chassis for the V8 conversion. I'll list the rough specs and show you what torture I go through when I visit ebay motors.

     

    350 block, bought it from GM Sports Salvage and the engine had been rebuilt.

    Mild cam I stabbed in at these specs: Hydraulic Flat Tappet, Adv. Duration 272/ 282, Lift .442/.465. Weiand Stealth manifold, Holly 650 DP, stock heads at what I believe to be 76cc--but I'm not sure.

     

    Here is what I have in parts to add: Edelbrock RPM heads with roller rockers (I have 2 sets of aluminum ones and one set of steel rollers). The heads are 62 cc heads which would bump the compression from 8.5:1 to I believe 10.1:1! I'm guessing on the compression ratio increase, but I think I'm close.

     

    So what is my dilemma? I see SCAT stroker cranks for sale cheap on ebay that would increase the cc of the motor. I don't have to bore out the cylinders and I'd like to keep the stock rods and pistons for now. What would the compression be with the stoker crank? I would think that I would be relegated to buying race fuel or E-85 to keep the engine running with cylinder pressures approaching 11:1 or more with this "old" engine, but the added cubes for on the cheap sounds pretty tempting.

     

    On the other hand, I have a T04E, downpipe, and Turbonetics wastegate from a 500+ hp Grand National and some turbo exhaust manifolds to make it all work. I could turbo the motor with a carb, which would be easiest to do right now, but maybe not the smartest...I'd love to do EFI, but there is no "cheap" way to do it right now and I have nearly all the carb parts. Maybe a MassFlo EFI system like Wayne uses, someday.

     

    The transmission is a WC T5, so without planning to drag race it (much), I hope to keep the T5 I have. In the future, a G-Force T5 would be in the works.

     

    Just some other specs: 3.9 rear R200 on the car (also have a VLSD Q45 diff too), Eibach lowering springs, Tokiko shocks, urethane bushings, etc.

     

    The car would be a "dual purpose" car, for mostly street 'sport' driving (I did not say racing, so don't go there) and maybe some track use. I do not plan on making it a race car. At least not yet, anyway.

     

    Given minimal cash outlay, would you do a stroker crank and run special fuel for a mostly street car, or would you stick with the 350 and call it good?

     

    Keep in mind that the idea is MINIMAL cash outlay. I can build a proper 383 in the future when the time comes, but I won't go half way with that...
