L28+(maxima)47 build
Been working on a replacement for years - lol. I knew this intake would probably be a restriction - especially for NA . I have a Canon manifold that has been taper bored and drilled for bungs . Plenum needs to be welded on . Might use same throttle body for now . I also have a diesel intake getting converted to a manifold style fuel rail and injectors.

Sure - the thread topic is misleading at this point 3.2 L N42 block prepped by Rebello. 10.5:1 CR - 89mm bore kit . Which includes diesel crankshaft , Eagle rods , JE Pistons. He basically sent me the prepped parts and I assemble the motor . MN47 Maxima head with 44/35 Manley valves . Steve Bonk 535 lift cam , ISKY springs , retainers . BHJ damper . Kameari tensioner kit. Using a stock N42 intake with a 240sx TB . ECU is Megasquirt 3 - full sequential 42lbs injectors . D-585 COP ignition . The stock manifold was choking the engine and power started dropping at 5800rpm . Still was making 200 HP around 7k rpm . Torque peak was 4300 - again early , but the N42 has 31mm runners , so sucking through a straw.

Made it to the dyno today . Pretty happy with the numbers , but was happy before I ever saw them. The car is just a beast and fun . Did 226 rwhp and 226 torque . My stock n42 is choking the motor , but hopefully be solving that soon.

I have to disagree with this philosophy. There are many that know in the heart and mind Trump is lying or is wrong , but “out of respect” for the president they will just follow along. He very much pushes the narrative and direction of the country . People are gullible - it’s been proven over and over again in world history.

L24 Engine Build, Head / Camshaft Suggestions
Many options ! MN47 head is a great alternative to a late E-88 head . It already has the good seats and a 35mm exhaust valve . If I had my rathers - I’d invest in a MN head . Drilled cam is better than spray bar . Closed chamber head - better for detonation . Smaller chamber for CR . Go with 44 mm intake valves L24 block can go with L28 pistons if you find the right machinist to check wall thickness . If not - go 1mm over on the bore . camshaft ! ISKY cam 490/290 or Steve Bonk cam 530 lift . I think the aftermarket pistons come with reliefs , so a little more room for valves .

COVID-19
When numbers get to 1/2 million deaths the circle will get closer . Maybe then people will understand? Watched a great documentary on the Spanish Flu. The similarities are striking . Another time when politics got in the way of saving lives . If this strain was as bad as that one , we would be in worse shape yet. I feel for the kids that grow up in this generation and have to put up with our selfishness . If we were in an actual Cold War with China or Russia and we knew they started this virus , would we still be insistent to protect our rights to choose to wear a mask ? If the government said it was our best defense against the war , would we help our brothers out ? Makes me wonder .

Spirit Garage / Fujitsubo Header Exhaust Flanges...
What a shame . It’s a pretty piece , but if it don’t fit , it don’t fit . Not sure how would even modify it correctly for a lefty . Maybe your fix was about it .

I have a 12” disc table sander - HB special. Good sander for most projects

Here’s my remedy - I don’t recommend this to anyone as a disclaimer . You will notice the one pic showing the distinct bulge from the weld bead . The fit is so tight that it makes a difference . I’ve grinded enough welds to feel confident for myself - but won’t tell anyone this is the fix . Even with this “fix” the cartridge still stands tall in the housing .

The rears weren’t the problem for me - it was the fronts

KONI Sports for Classic Z's
Not really - by Koni . I resolved it myself . I did some sanding on the welds on the bottom of the strut cartridge so it would drop in further into the strut and I got a few more threads on the nut . I still didn’t make the minimum mm stat. I felt the gland nut was secured enough for me . This was only the fronts . The backs dropped in with no issues In conclusion I was told that something was odd about my strut housings , though others had the same issue . MSA said they provided all three series of struts . I bet there was more than three versions . They wanted me to try and grind the inside of the strut tubes at the bottom of the strut ? I call it BS , but maybe I don’t know what I’m doing

PM me pics of what you have . I might try a header rescue - or I might be sorry I tried +lol

Thanks - maybe I would take a wack at modifying it . Not sure if your selling it. Crankcase breather I’m assuming ? How bad was that collision . Wow- this thing was really off

So how close are the primaries on the inside towards the block/trans ? How thick of a flange do the Spirits have ? Thanks for the pics

Spirit Garage / Fujitsubo Header Exhaust Flanges...
Pictures would be nice if you have any . Sounds like a guy with EFI might fair better with the one issue being close to the carbs . Interested to see the clash on the steering shaft and other issue . Wonder is someone with skills and a welder could fix it to work .

And thanks for the review on the header . I had looked at that system but also thought about others . Glad I have my 300$ MSA header now !

So your asking if the flanges will match up in size and placement between the FUJI and the spirit ?

L28+(maxima)47 build
Thanks for sharing . All but one were made in the last 20 years . Jeez - I’m glad I’m faster than a 300 Chrysler - lol. Working on a diesel intake conversion for the motor . This will be interesting . Much .bigger and longer runners . I’m a month out from a dyno session

Question re: Setting Timing on L24 ('72 240Z)
If your talking to me , you maybe be off a drive tooth from the oil pump gear . Have you removed the oil pump at all? Has it always been this far off. Is the tang at 11:25 o’clock at TDC ? Have you had the engine apart or oil pump out ? Is the rotor pointing at #1 spark plug at TDC - possibly the wires are one hole off

KONI Sports for Classic Z's
Well I like the way they ride . I’m running about a 1/4 turn out for all these wonderful roads around here . The ride is decent and can be made softer than my non- adjustable KYB’s - but just a smidge . I take a long drive tomorrow so I will really give them some miles . Nice curvy Indiana roads . I’m taking my friend gearhead with me for the ride . Actually I’ll have two passengers l but cranky arse has to stay in the back .

I think low 4 is possible if I can hook up or burn up my clutch - lol. I need to do a quarter mile , the GPS can time that too!
