Rb24 Block In Laurel

[RB34Medalist]

okay then. i really i just want to get it running so I can sort out every problem I can in the mean time

No, you can ignore what StevenCJR31 said, because it's not true.

bullshit. . ive got both motors side by side here and the intakes from the r32 rb25de and r32 rb20det DO NOT swap over they ARE different, dont go quoting shit

That's not what we're talking about. He is talking about putting an RB25DET head and inlet manifold onto an RB24S block. The block of the RB24S is the same as the RB25 block (except perhaps it has no oil squirters and possibly no hole for the knock sensor(s) ).

So your post was completely irrelevant, and it sounded like you were talking about RB24 that was based on stroked and bored RB20 stuff - which was NOT the topic of discussion. So I kindly invite you to back off.

intake manifolds visually same but different stud pattern and the na 25 has bigger ports

[StevenCJR31]

this is what im talking about! ^^^ as i said before - the manifolds are visually the same but are in fact different so you can back off and rack off yourself!

[GTSBoy]

But what has RB20 ANYTHING got to do with the thread?

[StevenCJR31]

absolutely nothing . . it was in answer to what roy said on this thread on 01/03 at 14:23 about the intake manifolds being VISUALLY the same on the na 25 and 20dets, i was mearly pointing out that whilst visually the same they are in fact different port size and stud pattern and therefore not interchangable, same top feed fuel injectors and fuel rail tho

I tell you what, we really need to fix the new forum software so quoting works properly again. I had to go over those posts 4 times to follow exactly who was saying what again.

I apologise for coming over like a dick. I should have said "not relevant" instead of "not true".

all good. . .this phone is a p.i .t .a to use on this forum thats for sure!

NA RB25 has no oil squirters either iirc, just the provisions for it. But having no hole for the knock sensor, would that be a problem?

I'll be getting the engine this week, thanks for the help guys.

Hole for the knock sensor could be gently drilled and tapped (give the example to follow on the other block). Worst case you do not install the knock sensor to the block. You just connect it to the wiring loom, wrap it in foam.bubble wrap and gaffer tape it to something solid. Or an even worse case, you don't connect it to the loom and you just put a resistor (there's a certain value you'd need, search it up) across the loom plug and the ECU won't know any different. Either of these leave you exposed to a little knock damage if your tune is a bit ragged or you get a gut full of bad fuel.....but that's no different to most people who are using aftermarket ECUs anyway, seeing as they don't usually use the knock sensor either.
