Interesting Ebay Finds... 175HP L20?

[Logical1]

While I'm broke as shit and dreaming of parts I have been browsing around craigslist and Ebay alot... I have seen this guy on ebay a bunch and I know I would never pay $1800+ for a L motor. But I am curious if anyone knows this seller or if he might even be on here. He lists a 'Datsun 510 620 2.3L L20B U67 Performance Race Engine' with unknown exact HP but it should be around 175 :unsure: I emailed him about a complete parts list of all Frankenstein parts. He wrote back and I quote "I don't like to type and talk, call me." Here is a link to the listing and the essential info from it for after the auction ends:

All his feedback is positive, It just seemed like a bit of snow job to me at 175+ non-turbo... Curious as to what the experts think! (Mike) :cool:

 

I also Ran across this crazy head I hadn't seen anyone talk about before that sold for $400.00 in used funky shape...

My link

 

BTW Everyone said it already, but the new search engine SUCKS! especially the 'advanced search' not much of an advancement from the basic... So my bad if this seller has been covered, but try doing a search for Datsun-parts LLC and see how many results you get :P

[motavated]

He is on here. He had a blue 620 that he just finished. He might not like people talking bad about his stuff. Honestly.... If your going to pay that much... Get a KA....

 

From what I remember he had a L series engine on his 620 but is going to swap a KA instead. Why swap out the built 175 hp L series engine for a 155hp KA? I find that very weird...

[Logical1]

No disrespect intended, I am no expert! I haven't seen those Hp figures around without turbo though, So just curious and thinking that's alot of money to spend on a L...

[datzenmike]

Salesmen are slick when talking to them in person or on the phone. Any lawyer will tell you never to put anything in writing.

 

All L4 heads are solid lifter so saying so is redundant.

 

"HUGE ITM KA24 89mm OVER-SIZED PISTONS AND RINGS" KA pistons are 89mm and so can't be called over-sized.

 

This is a 4mm overbore on an L20B block, do-able but would be safer on a Z22. If the head wasn't shaved this would only have a compression of 8.99 which isn't that bad. A 290 cam is a bit much for a DD so I think this would be better for summer driven garage queen car and not a truck, but just my opinion.

 

I think Byron has a LZ22 with a healthy cam and multi-carb that made 138 RWHP so draw your own conclusions.... If this is 175 engine hp I guess it's possible.

[greybeard]

I believe that amount of power is possible from a 4 cyl. L series without a turbo, but NOT without headwork.

 

Remember the cylinder head is the key to power in any engine.

The 2010 Altima's 2.5L DOHC engine has 175hp at the crank...

 

Tell you what, put that engine in and I'll race you in my 180hp Z-car. You should win with a lighter weight vehicle. :D

ill do it!

@ canby this year??? :D

 

when the LZ22 is in, i think itll be >150.

ill have to get it on the dyno at some point.

ive probably spent that much so far :blink: ... w/o counting the EFI that may or may not go in.

 

 

ive heard good things about his builds.

[Drahzzel]

175hp is definitely possibly as he mentioned with the right intake, exhaust, flywheel, etc. Engine horsepower differs from whp/bhp in that it doesn't factor in the drivetrain loss and is the figure most commonly used these days when people quote horsepower numbers on stock oem vehicles. Most power can be had by reworking the head with lighter/stronger components as well as a good port job, but there are also many other factors that contribute the horsepower number and your power at a given rpm range. It really depends on whether you can build your own custom parts and how much math you want to get involved in. ;)

[hang_510]

how much math you want to get involved in. ;)

its those damn decimals between $$$$ that kills me :angry:

[Logical1]

Well sounds like its pointing towards possible to pull 175Hp out of a L. WOW! :thumbup: Now I have dream to work towards (not that I'll ever get up to that)His motors and work looks beautiful, I just felt that something was up when it wasn't put in writing like mike said ;) I picked up my L20 for $150 B) so I'll see how close I can get to that number for hopefully less then $1800! (even if it takes years) Planning on doing all the work myself besides the boring... I know the common opinion is to just put a newer motor in but I just love the simplicity of the L's. Holding your own against ricers with a 40Y.O. Motor feels good too!

[78kingcab]

his name is al(datsun parts) i got parts from him he seems to be top notch...his builds deffentaly are....as for the motors i belive rusty(rubberman) has one in his newly finished 620 ...maybe we should ask...ive always wonderd about these myself

[Pacific coast Datsun]

I bought a L 18 from Al several years ago & have had no issues with it.

His parts / engines are well put together & at the time he gave me a break on shipping cause i went to his place to pick up the motor.

[74datsun620]

I have bought cosmetic parts from datsun parts and they came fast and looked great. I too would love to know about the motors.

[Rubberman]

arrrrrhhhh, as I bite my tounge, I'll have more to say on this subject later. To see more on my situation go to http://www.datsunminitruckin.com/ under 620 thread "ole blue"

Holy Shit! That is a Gorgeous build! If I ever had any doubts, they are gone! Obviously Some other folks would like to know about your Engine's and I hope this thread makes clear how kick-ass they must be :)

Logical, THESE ARE NOT MY ENGINES! Wanted to make that clear. I had bought one, did you even read my build thread? And it doesn't look good at the moment. I have been very calm about the situation, for now.

[datzenmike]

 

If you look at the #3 exhaust pivot and lock nut, they appear to be much closer together. So did the lock nut loosen and the clearance increase until the rocker jumped up on the pivot and jammed the valve open to be hit by the next piston TDC. It would have jumped off the next time the cam lobe came around. I would expect the piston has a nice crescent shaped mark on it too.

[Rubberman]

Mike we really didn't mess with it after we took the valve cover off and found this. I moved the rocker around and theres so much pla under the cam the valve has to be bent, and the spring is compressed down. I did'nt even think about the piston, hell I'm just pissed and frustrated right now. I'm in contact with Al, so we'll see. There's alot of money in that pic.

[datzenmike]

I feel your pain. :crying:

Oops! Was early (for me) and just glanced at the photos, still a beautiful build, Sorry to hear about your troubles :(

[Rubberman]

Well, here's the problem, valve seat came out, bent the valve and put a ding in the piston.

 

 

 

 

 

[datzenmike]

Just my opinion here, but I would say the bent valve hammered the seat out.

[Rubberman]

So Mike your saying the valve bent first? What would have caused it to bend? I figured it would have been the other way around.

[hang_510]

:huh: the rocker falling off the pivot which then jammed the EX valve open... BANG :angry:

[budsaipan]

What is the piston out of and what headgasket are you using for your motor?
