So thinking to put a rb26 on a rb20de. I think the bore and centres are the same, but i don't think bolt sizes are and the valves won't like the smaller bore.

At the end of the day, do you think its worth it? and why?

Thanks.

Well, it can be modded to fit, the topic isn't to be told what i shouldn't do. I plan on keeping my NA off my P's and keep it as a daily driver untill i get sick of it, and the idea of 140-150KW RB NA sounds good to me.

Just want to be different.

How do you intend to get this sort of power?

The RB20 is a much smaller bore than the RB26. So the combustion chamber of a RB26 is considerably larger than the RB20's. The piston at TDC will be like a dick-in-a-bucket fit into the chamber. The thing will have such low compression that you might be lucky to even start the engine.

And the RB25 bore is the same as the 26.

a 140-150kw would make an ordinary daily driver. a stock or mildly modded turbo skyline would be a better daily driver.

You do realise it is a modified motor, and therefore illegal - be it N/A or turbo makes no difference.

mohsen don't encourge him... this is why i hang out here to prevent stuff like this from happening. read up on gregs thread with the rb30 bitten end with a 26 head. thats the ultimate rb skyline natro you can make.... and as a daily i duno if you'd really enjoy driving round in a camed up natro just for the daily grind.

if you wana do.it do it, but its a lot of $'s for the sake of being different.

    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go. 
    • The roof is wrapped
    • This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.
    • Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
