I have emailed John Dixon about his crank but not had a reply.

For $3700, you can pick up an engine from Car-part.com. I have also seen Titan engines on eBay for around that price range.

found mine at a local yard here for 1400.00 . i also found a vk45 that had been flooded during katrina. i was able to talk the guy into letting me have the crank b/c he was gonna be selling the heads and other parts to others.

by the way. i got the vk45 crank for 50 bones

So you saying that u have a spare VK56 crank.....

No, I was just politely trying to get you to see you're not thinking this through very well.

David Steele wrote:High fuel consumption you say. well more air more power, its comprimised, wanna save gas keep your foot off the pedal.

My point was more in regards to burning a ****load more fuel for a lesser gain in power. It's a less efficient means of making power.

David Steele wrote:I have a couple things to say.

Rev like hell? No thanks dont need to rev higher with the right stuff. I dont want a peaky engine with a high lift camshaft that makes your low end suffer greatly.

A peaky 4.5 litre with **** low end ? Rahahah, it's a VH45DE V8, what motor did you think I was talking about ? Since when did they have crap low end ? I didn't mention changing the cams... you throw boost into it with some bigger injectors and perhaps do defrag's increased valve lift mod to the heads... easy 700+ HP to be had, and that kind of power is nothing to scoff at ! I'd wager you couldn't even handle that kind of power, so what makes you think you need 5.6 litres to make even MORE ?

And since you'd need to modify the crank to make it fit, why not invest your money in developing a VH45 flat plane crank & cams to suit? Probably cost the same. Then you could rev it out to 9000RPM and have a serious engine, much more potential than what a dirty old VK56 crank would give you.

How did you know I wasnt going to modify the rod stroke ratio for less angle and aswell as move the piston pin up in result having a longer rod which basically. Gives me something better than the orginal with more displacement.

Dream on... how much are you planning to spend ? It's looking more like $20k now. Have you thought about how you'd end up twisting your piddly little S13 chassis into a banana shape, and shatter every single driveline component into a singularity ?

David Steele wrote:Cost? IFthats the problem I would've gotten something with some aftermarket love instead of the ''one off'' custom parts engine.

No offense man, I love the ideas, but in my experience... taking something to this level is really only if you want to be involved in some kind of serious competition work & have got ridiculous financial backing & sponsorship. Some form of drag racing, or top level circuit racing. You come across more like you're conceptualising and daydreaming about things. Sometimes it pays to listen to the knowledge other people are trying to share with you, that's what Nico is here for after all.

ultrapulse wrote:So you saying that u have a spare VK56 crank.....

not at the moment. my machinist and i are using it for comparison purposes right now. in the near future it may be avalible though. that is inless i try finding a vk45 to try and stroke. not hundred percent sure at the moment.

some tidbits of info for everyone. upon disassembly of the vk56 we noticed how well engineered this motor is. a big step forward from the vh series. looking at the bottom end and the block, i we tend to think it would be very capable of the 500+ horsepower figure on the stock bottom end. much of this is due to the block itself. one of the biggest killers of bottom ends on a motor is unwanted flex and vibration. that being said, this block is STOUT!!!! cross ribs everywhere, thick skirts on the block, and good hardware. it's nice to see a car company that finally built an engine and didn't cut corners.

Wow its a ''V8'! Its a small V8 that makes nothing stock.

''Since when did they have crap low end ? ''

They make about 190-220 whp stock I have stock Honda Engines that dyno that much and there 2 liter engines in other words to me thats complete crap.

Simply put bigger engines make more power easier faster sooner. This is why there are displacment limits in a majority of motorsport anything to say about more efficient bull is pointless here. This isnt 1950 where 6 liters made 190whp from a production car.

My piddly little s13 chassis how much are you going to assume about me?

Its none of your buisness what or where my funding comes from keep it that way. Taking stabs at what you think I am is useless. You dont know me or if I own a shop, if I do my own fabrication and engine developement.

If you can help your self I'm asking you please dont anwser me if you want to try to profile who I am / what I'm doing or about my income/funding.

This is a simple reasearch on stroking this engine nothing else. kthxbye

The displacement isn't the only factor in that kind of power. The VH might put around 200whp in stock trim, but that is due to alot of factors like a long runner restrictive intake system, weenie cams, more power loss through an automatic transmission, and a very conservative tune on the stock ECU. You eliminate those factors by doing say an ITB setup, a standalone ecu with a good tune, some new cams, and put it in front of a 5 speed, and the wheel horsepower will improve alot!

Also, the honda motors have to rev up to 9k to make that kind of power which means less power under the curve. I got to drive my friend's S2k, and it felt slower than a civic until it hit vtec (around 6k rpms), and then it was like flippng an insta-boost switch. Horrible powerband, but it would haul around the track as long as you kept it in powerband.

Yeah I won't be discussing this with you any further. You're taking it far too personally, and giving some pretty irrelevant answers (like the thing about the honda engine, in response to my statement about BOTTOM END POWER) q-

I thought everyone had come to the conclusion that David Steele is a 15 year old dreamer that is off school sick?

I hadn't, but I felt compelled to post in this thread... I've only ever read the knowledge and advice of others here on Nico, this forum has some of the most clued up & technically minded people I've discussed stuff with, I will most certainly continue to respect the opinion of most members here... an example that David Steele could learn from.

It would be great if you can post some pics of the VK56 block for us?

From what I have seen, the VH45 bottom end seems stronger with its bearing girdle and chunkier looking block. Would be nice to do a side-by-side comparison.

When ever it comes available, I will be veeery keen to get it sent back here, or sent to a mate over there to pop into the next car his company sends back. Believe me I'm keen, so pm me etc once that inspection is finished and u decide not to vk45 it .

defrag, how much do you reckon the ITB's ecu, aggressive cams and 5 speed will output?

and with the ecu, the question of the use of standalone or tweaking the stock ecu has never really been answered for me.

and what if i throw escort racings high comp pistons in the mix?

That's the setup I'm doing in my rx7, and with a megasquirt + ITB's using the stock lower manifold runners + some cam regrinds with a hair over .400" lift, I'm expecting to get at least a modest 300 hp at the wheels through the stock auto with a higher stall verter.

With some headwork, mid300's and more should be possible while staying n/a.
