forged internals for a vh45

[FandGMotorsports]

We found a way to use a common high quality H-beam rod and a special lightweight dished forged piston inside the vh45de. Compression ratios vary from 8.0-8.3 depending on overbore and surfacing of cylinder block and heads. We put a single Turbonetics t-76 on some custom manifolds with amazing results. We are soon going to be offering a rod and piston combination to fit in the motor. We estimate that combined with quality machine work and our rod/piston 800plus horsepower should be easily obtainable. email inquires contact [email protected]

Way more info and research will need to be posted if you want any serious inquires here.

Sounds good, on paper...

That's the 7th time you've posted the same info.

If you're here to share info, then let's see some solid info.

it's gonna be expensive, i'm afraid that if i tell too much the work i have already done will just be copied. the combo only requires one special feature, the crankshaft must be machined down .060 to accept the rods i use. other wise it's plug and play. the pistons are high qualtiy 26 series forged aluminum and the rods can come from any big name. in most cases we'll use an Eagle or a Scat rod, but a carillo or a crower could be used also.

Well, it won't be the first VH built for boost.

Like I said earlier, Slim is running a Z32 with a built VH45DETT. There's a few others here (most are in AU), and don't forget the plethora of Indy 4.1 engines still out there.

Just build it and dyno it if you're so worried about people "copying" it.

There's 2 VH's sitting in my fabricator's shop awaiting their forged internals... no secrets.

IMO if you are using a simple and easy method and intend on charging people for the information thats pretty weak. I will have none of it in my forums.

BY the way, we have already discussed using some chevy rods on the VH, in the VH forum.

Those 2 threads demonstrate for most builds that arent over the top you dont even need to touch the internals. Lets use what Mr Myiagi gave us!

PLEASE dont get me wrong, I am not going to be a downer on this, if you want to come in and share info for the benefit of the community, then by all means, welcome to the forum and I hope you enjoy your stay.

your right....it's a 6in chevy rod, and the math does work out, i had a block sonic checked and found that a .075 overbore isn't going to work (safley) (by the way the .075 would put the block in the realm of a stock 305 piston) also the rod discussed in the previous vh forum is too short and the piston won't clear the counter weight, at least without some extra machining, plus the 5.565 rod length would decrease the rod ratio. i was inspired by the information found in this forum to start in with more research. i found a good custom piston supplier through my speed shop i run but wants 80 pieces (10 sets) to make the order. i already bought one set but they cost a fortune. i know this motor has huge potential but need to lose to the cast pistons to get the extra power. the only obstical that ive found is grinding the rod journal down .060 to fit the chevy rod and having the rods slightly narrowed. the pitons have the light .043 ring pack and use the easily obtainable chevy pin, you could even use the H-series bearing for extra abuse. what does everone think?

Very nice. What I suggest you do is post in the VH forum, as the VH guys are already chomping at the bit to hear this sort of info.

This is where the party is at! zeroforum/193

Thanks for sharing the info, and id really like to see you post a full writeup on what you've done with the car in the VH forum. Some pics and maybe a video would go a long way!!! The VH guys are gonna love this kind of stuff!

BTW, have you tried this setup (IE is it what you're running) or is it still in the experimental stage?

[FandGMotorsports]

its still somewhat experimental, i have the rods pistons and block assembled buts that as far as i got right now, the project is really expensive. i also was working with cometic to have a custom head gasket made. i'll post my stuff in the vh forum also

[elwesso]

Did you ever have the car running with the turbo on the stock motor?

[FandGMotorsports]

only as an sr20

[94infinitiq45]

Are the stock rods and crank forged? thanks

[sijoko]

Are the stock rods and crank forged? thanks

Yes, the crank is twist forged and the rods are forged as all Nissan rods have been for years.

To the original poster:

My question is why the 6 inch Chevy rods? I think that using the 5.85 inch rod is a better bet since you won't have to cut so much off the crank. Also, can your supplier make replacement forged pistons for the VH? I think that a lot of people would buy the pistons by themselves. It gets expensive to grind the crank, buy new rods and new pistons.

I am with Sijoko on this one. Reducing bearing area is not a way to gain longevity at indreased power levels.
