None are stock.....all are modified L28’s.....HP varies from 190 at the flywheel to 250 (Stroker). Only thrash em in a straight quarter mile run.....Quaife R180 ok? I don’t really want to do an R200 swap if not necessary.

Thanks Tom.....you bet I’ll take it to a pro then. Is the Quaife unit stronger than the stock? Would that eliminate the need to go R200? How much horsepower is too much for an R180 Quaife LSD ?

Just curious Tom and Mike. What is involved in buying the Quaife R180 LSD insert that Whitehead sells and installing in our existing R180 diff? Is that a job for the do it yourselvers or is it a job for a diff shop?

Thanks Mike.....cool site....hope to see you at ZCON this year. Are you coming?

Sounds great.....can you PM me their contact info and web address. Thanks Mike! Guy

How much was it Mike and can you use the stock 240Z half shafts without mods?

Wow.....You’re really moving ahead. I don’t think anyone on this forum realizes how incredible this build is going to be Brandon. It’ll be in magazines for sure.....can’t wait to see a little Safari Gold color applied.....perfect blend of old and new, along with a beautiful new RB 26 NA. Charge on!

The site works great Steve. How’s it shaping up?

Had a spoiler installed on my 73. Before and after. Also, we booked our hotel room for ZCON.....18th, 19th and 20th.

Looks like you have most of your body parts now. Can’t wait to see this rendering come to life!

Agree.....I think it’s an RB 25 or 26. The main bearing caps are all joined in the picture.....twin cam......really cool engine.

Hi Mike.....I think it’s great that you bring back these old posts.....always fun to see some of the early members.....keep em coming. Guy

Lumens.....Here are the 73 pistons shaved and installed. If you decide to have them machined, do it before you install the rings.

Me too Blue.....I’ll buy you a drink!

Glad you found these specs on the 73 Nissan piston Blue. I had noticed the taller piston back in 2012 when I bought some .040 over 73 pistons from my local Nissan parts guy (they were still available). I tried to find out more info, and no one could help.....not even Sam Neves (built Greg Ira’s car) or Dave Rebella. I shaved the pistons .015 inches just to be safe. If the gasket is approximately .055 inches and the piston comes out .027 inches, you have .028 inches clearance. If that isn’t enough, you either shave the piston or use a thicker head gasket......question is how much (or little clearance) is enough.......anyone got that answer?

This is the coolest project! 510’s just make me smile. My son had an orange 510 too......good luck Cody....it’ll be special.

Interesting.....anyone on Hybrid Z know the compression thickness of the stock Nissan head gasket?

I agree with madkaw......one exception......if the block was machined. It would be nice to know what the safe clearance is between piston and head (drag racers install with almost no clearance), and you can get numerous answers depending on who you ask. . Valve clearance should not be a problem because 73 pistons are flycut. The stock L28 pistons come out about .018 inches with no problem. If the block isn’t decked , I would think the stock gasket would be fine. If you are concerned (if it keeps you up at night) you can always shave the top of the piston down to the sleeping point.

If you are concerned, you can always shave the pistons .010 inches or so. The crush on the stock head gasket is about .055 inches, so clearance should be adequate......I would think C/R should be bumped.....not the head lol......that's a good thing!

See you in Atlanta Blue.....looking forward to meeting everyone!!!

AARP260 just bought the engine......congrats Craig....I built her with tender loving care and all (and I do mean all, down to the front cover and oil pan bolts) new parts. Guy

P30 block.....L24. Block number 077270....from a 1972 240Z.

Niiiccceee!

You can do all kinds of swaps.....been there done that. You’ll need a good frame shop ( and $$$$$$) to make sure everything lines up.

Done
