Rb25/30 Gt35r Help Needed R33 Skyline Gts-t

[PM-R33]

Here's a question for ya, you mentioned a plazmaman plenum. Will this fit under the bonnet with a RB30/25 since the RB30 will raise the engine height a bit? Because i've looked at mine before and i swear with the extra height of a RB30 the front of the plenum will hit the bonnet.

^^^^^Have you seen what else they have run on the stock bottom end. There is a recent post by rips in the rb30 section. A built standard bottom end will handle that with some mods.

quote from rips

I can also vouch for stock RB30 cranks to 9000rpm 1000+hp, and stock RB30, pistons and rods to 8000rpm and over 500rwkw in a track car without problems, although I usually tell my customers 7200rpm, 1.5 bar 400rwkw.

If have money to burn.....

yeah, that's why i was saying to go for the stock rips bottom end, but just make sure oil mods are done...

Why dont you guys just build your own engines? Do a bit of research like everyone else (there is so much of it on this forum its not funny) and instruct an engine builder to build it to your specs. You could do it for half the price

[joeyjoejoejuniorshabadoo]

because i'm lazy and rips are experienced and well reccomended

Agreed... Between the PDF, Oil control thread, and the conversion thread theres not much else you need.

...apart from the tools, the time, the space and the confidence that you wont make an elementary mistake that will involve having the engine pulled and the job done properly by someone you should have paid in the first place.

[Bliksem]

We were saying you use those resources to instruct your engine builder your specs

haha +1

Furthermore, I just don't have the confidence to do it myself and ask a mechanic to build it. WHat happens if I get something wrong, I can only blame myself, whereas if the mechanic does it all, and something turns out foul, you can point the finger/gun at him.

But yes, as always, there is a premium associated with the mechanic doing all of this.

I guess it's too late anyways for me as I've already paid the mechanic.

Might be different in a 33 but I looked at that and it definitely wasn't going to fit in my 32. That is why I had a custom manifold made out of my stock runners and a 26 plenum

Yeah thats what i thought. I dont think a plazmaman plenum will fit under the bonnet on a 30/25 in a skyline. Might have to look into this Turbz-RB25.

[TiTAN]

you can run one, guilt-toy has one on his.

[TAKUSHI]

Correct me if I am wrong, but isn't $8,700 for a fully forged RB30 engine a little too expensive?

my old boss had to fork out roughly 10k on his rb30 block but that had block strengthening done to it as they prone on cracking

plus depends what brand you're using, also you're getting it all prepped for the forgies to go in, so yeah i'd say maybe not quite that

but very close to it

Thanks for all the comments guys.

Prone to cracking? More info please, RIPS 8 second stock bottom end seems to differ. The only part of the rb30 "prone" to cracking is the oil pump, and thats if you use something other than an rb30 pump.

For $8700, i would be wanting a high end oil pump.IMO its the first place you should spend the money on an rb bottom end(although i didn't)

[Turbz RB-25]

This is what is included in the package:

Used RB30 short engine

Drilled and tapped to fit RB25 head studs

Engine is stripped and chemically cleaned

Block rebored and torque plate honed

Head gasket surface CBN milled to suit MLS gaskets

Crankshaft balanced, micropolished and fitted with screw in oil gallery plugs

Oil pump drive collar supplied and fitted

Connecting rods resized, fitted with new bolts and pin bushes and balanced

Short engine assembled using new forged pistons and rings, ACL race series bearings, new N1 oil pump, seals, painted and fitted with oil & water plugs.

Plus the mechanic is porting the head, as well as fitting the bottom end to the head.

So it's not just the engine itself, it's the porting of the head and fitting the block which raises the price to $8,700.

Not to mention that exchange rates have an impact upon parts, so stuff would have been cheaper in june 2008 when our dollar bought 0.98USD.

Cheers for your help fellas

eeeeeeeeeek your telling us its $8700 for a $3000 port job and then $5700 for a basic rebuilt with stock rods and crank?

Sorry, rods aren't stock. they are spool RB30 forged H-Beam rods.

They cost around $850 just for themselves.

So you guys still think it's expensive?

[Bliksem]

Why not shop around? That should give you an answer...
