225 hp l18

[Braden]

please tell me i am crazzy and this is true, ive read some of todd walrich engine specs and i dont remember any of his l20bs coming close to this, 179 hp naturally aspirated l18? and his friend has a 225 hp version? wtf? please tell me this is true!

[Braden]

if you go to you tube and watch it you can see the comments, lets get all this guys secrets lol

[Braden]

i cant see this engine being very reliable if they port it out that much!and put that much stress on the valvetrain. i still cant get him to let out what type of fuel delivery system he is using

this evidence is against him but he did mention rebello etc. maybe this is plausibe just so far on the west coast we havent heard of ti over here, somebody here has to knwo this guy, maybe he is on here

It's possible, just a LOT of money and generally custom head work. They probably only have about $14k-$20k into the motor on that one. :blink:

[DISLEXICDIME]

you can build a 225 horse l16 but it will only last 10 races and is not very street able .

[datzenmike]

... and is not very street able .

 

No shit. Everything is above 7K. Imagine pulling in and out of the supermarket with that.<_<

[HRH]

True that, look at that Pikes Peak Tacoma some years back. 1000hp 2.0 liter, but it only needs to last for 15-20 minutes.

[HRH]

A good saying to live by for racers: You can have speed, reliability, and cheapness, but you can only have two at a time.

[Braden]

you have to have alot of passion for the nostalgic l20b to put that much time money and effort to get that little of gain, you could build a 1000+ sr20 or ka24 for alot less money than that! and it would probably be more reliable, hell i owuld try and build some sort of turbo 2.0 around here if we had a machine shop that was worth a damn and if i had someone around here who wasnt a complete honda ricer meth cooking goverment sucking 2nd grade toothless idiot

20 years ago here in the Northeast the L18 was the engine to have if you were racing circle track in the Pro 4 Division. The parts list was a whose who of the best in performance parts of the time. They included Cosworth pistons, Carillo rods, dual Weber 45's, BC Gerolamy head work that included angle milling and port welding/relocation. They were claimed to have 235hp and were actually quite reliable. My A15 in my SCCA GTL spec Datsun 1200 (with restrictor removed) makes 156 rwhp, so I can beleive the 179 rwhp on an L18.

 

Here is my dyno sheet on my A15, not the most reliable at just under 16:1 CR. It needs the head gasket replaced every other race to keep it from giving up during a race. (pay no attention to AFR, the 110 leaded race fuel was messing that all up)

that is possible.. i know one L18 in here finland wich does 187rwhp.. but only block is L18

And L24 4cyl :rolleyes: 237hp

You mean Z24 right ? :D

The block doesn't look like a Z24 block... looks like an L16/18.

well it´s still z24 block

Why are you posting stock L18 information and calling it "evidence" against one that is a high strung, high compression race motor? The concept of high compression race motors hasn't made it all the way to Kentucky?

[datzenmike]

The link I clicked on gave me this motor and it sure isn't a Z24 block.

 

And L24 4cyl :rolleyes: 237hp

At most it's an L18

 

[HRH]

Yep, no upper bolt holes in the timing cover. L16/L18.

[RoadRace]

the L18 with the 710 race car i have was dyno'd at 216, BSR head, all trick stuff. BUT - and a very big BUT - that was in 1980! how accurate was a dyno back then? who knows, how accurate are they now? same question. i have heard from other users that Rebello's seems to read higher than others, maybe they know something everybody else doesn't - who knows. i tend to look at dyno numbers like my wife looks at scales - if she has a problem with what she looks like, she will work harder until she is satisfied and doesn't look to the scale for approval. if you are slower on the track, don't blame the car.

umm because some of the big bore engines that are fully built dont even come close, so read the list asswipe

[defdes]

What's with the name calling? I was merely calling you out on your your inability to get your point across, your lack of versatility with the english language, maybe bad spelling and grammar ... oh, and the fact that none of those are race engines.

[Braden]

i stand corrected, you have won good sir!!!! feel free to tell us all you know about the mysterious race engines, wise one.

highcompression.. lots of time on a flow bench.. exotic rotating assemblies = high horsepower.. Useable on the street.. probably not. They sound cool though :)

You dont know how hard its to not put this in the dime due to the above reasons..:)

[Braden]

waaaayyy waaayyy to much expensive go fast shit on that motor to break or adjust!
