Zedyone_kenobi Posted September 10, 2014 Share #85 Posted September 10, 2014 You got me man. I have been swamped with roadster work lately. My Z gets driven often and enjoyed as the Roaster is getting new carbies. I will get that done. Just need to find time to have a dyno day. My one year old has been monopolizing my time lately Link to comment https://www.classiczcars.com/topic/49063-building-a-l28-na/?page=8#findComment-455181 Share on other sites More sharing options...
TheCrazySwede Posted September 11, 2014 Author Share #86 Posted September 11, 2014 Did you manage to get the Z out of the batcave or is it still boxed in? I need to hear your Z roar more often! It sounds as beautiful as it looks...and it looks amazing.

Zedyone_kenobi Posted September 12, 2014 Share #87 Posted September 12, 2014 Nope in my infinite wisdom I pulled the carbs on the roadster with the Z blocked in. Not my best shining moment of brilliance. Link to comment https://www.classiczcars.com/topic/49063-building-a-l28-na/?page=8#findComment-455247 Share on other sites More sharing options...
240260280z Posted September 12, 2014 Share #88 Posted September 12, 2014 no carbs...no problem...you can drive in electric car mode... just use the starter with it in gear to propel yourself.... not like an ion drive but just as much fun....and slow.

Travel'n Man Posted September 16, 2014 Share #90 Posted September 16, 2014 I spoke to Eiji about the crank options, and he mentioned the benefits of each (L28 vs. L28D)I told him I wanted a fast revving L28, at the expense of power if necessary. He told me the different rod/stroke ratios, and quite frankly, the diesel crank didn't really do much for me. One of his shop cars runs on a very similar setup as my motor, and he's pushing over 200 at the wheels, with a stock crank. I read up on a lot of Eiji's work (granted, it was very hard to find) but he really knows what he's doing. He's actually very well known in the JDM tuner's community and I can't argue with all of the happy customers I've talked to. I'm going with a stock crank, along with Kameari pistons and rods. The head work is still under discussion.Porting and polishing will help - it adds time to the build to get everything ground down but I'm sure that will help achieve your goals too.

TheCrazySwede Posted September 16, 2014 Author Share #91 Posted September 16, 2014 Aye, that's what I'm hoping. Haven't gotten into the details yet, as far as head work goes. I wanted to wait for the inspection results first to see if my head was any good. Eiji isn't one to fixate on HP numbers, and quite frankly, neither am I. I would like to hit 200+, which Eiji is confident the build will hit. Fast cars are fun, but fast engines are unique and special to me.

Travel'n Man Posted September 17, 2014 Share #92 Posted September 17, 2014 He may need your header (if you are going to use one) to get that exhaust ported and polished.Are you going to go with a lightened flywheel and a larger exhaust - what kind of carb system?If I had it to "do over" I would step up to a stage 3 and would have stroked it.It's kinda like building a house - once you have spent the time to design it - blueprint it - build a replica 3d model and get it erected - then you find the obvious things that you would "do over" again.

As far as carburetion goes, I'm upgrading to a triple Weber system. Bought a book last week about all the ins and outs of weber carbs, so I get my research done before I get my hands on them.

Zedyone_kenobi Posted September 17, 2014 Share #94 Posted September 17, 2014 no shortage of good weber help on this forum. But the book will explain how it works. Once you get that, you will not be so intimidated by tuning.Also, a wide band O2 will do wonders for your sanity while tuning.

Really looking forward to learning how to tune those beauties!

rbates Posted September 18, 2014 Share #96 Posted September 18, 2014 goal is ~ 200hp at the flywheel - what's that ~ 185 at the wheels ? what are you doing about the rest of the drivetrain ? the 280zx close ratio 5-spd & the R200 3.9 rear diff really wakes up these cars. If your CR is > 10:1 i would watch out for ping. Link to comment https://www.classiczcars.com/topic/49063-building-a-l28-na/?page=8#findComment-455673 Share on other sites More sharing options...
