I put up the details earlier because I have had quite a few members asking me not about stroker kits but lighter and stronger components to go in their race trucks.
Thus material type & cost was put out there for the people that have been PMing me about it after they saw it on another thread some months back.
I will even have a full set of parts ready to slot into an engine in the short future that I can post results up of.

Okay so you are talking piston speeds and such now.
The numbers you have come up with, how do they compare with a stock setup?
Gotta have a little snigger to myself.
I really am behind the times.
20 years ago we talked about it over a box then eventually someone built it over a box or 3.
You are still missing the point about the original question I think.
Besides that, you wanna talk about stupid business sense, you should really think about what you post.
R&D.
No better R&D than getting a idea out there, helping people to do it and getting the feed back.

I put the std piston speed up with the stroker speeds.
As for the second part of the post you have lost me completely.

Ok guys settle down, we can all learn off each other.
Northside, did you take into account that the guy using this crank will probly have custom rods and pistons that are stronger and lighter.
Lets save the rest for the dyno.

I wasnt having a dig at anyone, I was just pointing out some interesting things to take into account with stroker kits.
I assume he will be using lighter/stronger components also. Kudo's to him for building the kit and I hope it works out well.

Who do I call for a forged STD crank for a td42?

Are those roller rockers higher ratio than stock and would they fit a TB42(turbo)

I have one being made currently.
Only problem is after our initial R&D + engineering time etc.. that the manufacturing company has put in, they want minimum order of 10.
And at $3K a pop, its not something im just going to get in on the off chance of selling one or two a year.

How much hp and torque over the STD crank is the forged 1 going to be good for do you think?

Well the material used is about 40% stronger than cast iron.
Having forged construction over cast is already a huge benefit..
I would say over 50% more than standard.

Update, I have received my conrods and UPS have my stroked crank waiting for customs clearance.
Rods weight is approx 650grms on the kitchen anolog scales, so they are approx 550grms lighter.
Just waiting for pistons and pins now.

I have the pistons and pins and they look very nice. Finances are very tight and I have been considering selling it stroker kit and all. Watch this space.

northside.
hats off to you in your patience when you spend significant time on some of your posts.
as guys say, its just awesome to read the knowledge of people in the know.
and then copping crap from people on these forums.
very un called for. so hats off to you.!
marty, please chill out, this is a social forum.
if you want to know stuff, see the guy in person if your that keen.
see it for yourself.
no dig here, just respect each other is what it should be.
keep it a great site.
some people put a fair effort in their posts, its what makes this site soo good.
and in general, you determine yourself if you want to believe or not.
see for yourself.
keep up the good work!!
get a real motor, 1HD FTE!

I would like to know more about the rockers please?
Are they a custom make/off the shelf buy?

It must also be noted that it is easy to talk up a big game online. It is much harder to play the game in the real world. Results will speak louder than words every time. Facts a figures gents... and i emphasise the FACTS...
That being said good tech is good tech.

Is that a hint, or a statement?
I can see however that some work would need to be done, with the pushrod lash adjustment, but that's ok.
Anyone?????

Its running, still running it in befor pump mods etc, runs very smooth after dynamic balancing all the recipricating mass.
Plan to fit a laminova cooler aswell.

Nicely done mate. Don't skimp on the other stuff like the the intercooler otherwise you won't do it justice. It will be nice to see how it runs once you get the other stuff matched up to it like the pump and turbo etc. What compression did you end up getting? I know you didn't mention the chamber work that you had done on the head. Just curious if you had any problems with the chamber size and how you overcame them. Did you open up the chambers on the head or did you just dish the pistons?
Cheers
Steve

The hard part was already done for me by the Engineering company in America, the rods are shorter so the comp ratio is still 23:1 and there are no issues with clearance, the piston to deck height was .009" so no issues clearing the head with a grade 3 gasket. I did all the head work myself, I spent about 2hrs a day for a mounth porting and polishing the inlets and exhaust ports, should flow much better now, there was plenty of iron to take out of the exhaust ports, and I know someone will say why did you polish the inlet side, lets see what sort of debate that starts and what reasons people can think of:)
I had TD42T precomp chamber installed and I intend on keeping this engine reliable so I won't be making a dyno monster out of it, so they should be fine.
I will finish it off properly, does anyone know if Matt Mcinnes is still making Laminova cored coolers?

Yeah. Nissan heads are renowned for having a lot of extra metal that can be removed. I've seen pics of a TD42 head cut into sections. I can't remember where I saw them but it showed both the intake and exhaust ports. From memory there was plenty of room above and below to profile the ports for a much straighter flow but there wasn't a heap of room to make them wider.
Dyno monsters die when worked hard in the real world. So don't stress the haters that keep wanting to see dyno sheets. It should produce a nice big fat usable torque curve. Do your homework and get the torque curve nice and flat. You'll be able to use it much better in all situations.
As for polishing the intake. Well I've always been taught that on boosted engines to do this as the flow is already turbulent enough and needs the smoothest, cleanest path to and from the head and that for N/A engines you don't polish the intake.
There are a lot of for and against for each but it basically comes down to your choice and the application you are using for.

I dont believe he is. I asked the question, although not directly to him about 2 months ago when I 12mm IP'd my ute.
Are you still in darwin? I'd love to see this thing.
