Rb30 25 Neo Build

[Huzqld]

That seems too cheap to me =\

Just get your local hose shop to make some up (enzed, hydralink etc).

[iruvyouskyrine]

Yes I did when I ran low mount. Won't fit high mount and getting them in fixed size is shit.

Just get a local place to knock up some lines in the right lengths, it's a lot more convenient.

Looks like I will be fitting the manifold and turbo to the 25 first. Engine is a long way a way with cost wise. Will be fitting over the next few weeks. Then getting it tuned. Want it done by the 24th of this month. Have a track day on the 26th.

This is the port work on the head that I will be useing.

[lcxu105]

Well looks like I will finally be able to pick up the bottom end in 2 weeks from machine shop. Been a long time.

[lcxu105]

Ok. So I have the bottom end back and about to bolt it together.

Just wanted to know what head gasket everyone uses in the rb30 25 neo builds. I know what thickness I need just not aure on witch one to use.

25 26 or 30.

Whats the best one?

[Ben C34]

30

[lcxu105]

Ok thanks for that Ben. Have heard so many people say different things like 26 has built in o ring in gasket so wasn't sure.

[iruvyouskyrine]

They are all 1.3 mm as well. I used a 25 gasket on mine but it really shouldn't matter much.

[lcxu105]

Ok so have picked up the 30 head gasket and now trying to sort out the timing belt. Do you use the 25 tencher and idler or do you use the 30 ones. Also what brand belts is everyone using. Tried to find a t291 gates belt in racing series and gates Australia don't have them. I know people use the dayco std one but wanted to have something with better quality thats all.

[AngryRB]

Its all in the RB30build pdf, I used 2 X RB30 tensioners (double row bearings)

[iruvyouskyrine]

One tensioner and one idler (25/30 doesn't matter same thing) and jut a standard Dayco belt. It's only an old rubbish Nissan slap-together job anyway, doesn't need anything special.

[lcxu105]

You didn't read the question. What is the best brand belt to use and do I need the 25 or 30 idler and tencher

[iruvyouskyrine]

You didn't read my answer.

Use any brand belt you want, it doesn't matter unless making huge power. I used a standard run of the mill Dayco belt.

Seeing as RB30 doesn't use an idler you may find it hard to use that. Like I said RB25/RB30 use the same tensioner bearing so it doesn't matter.

[Ben C34]

Word.

[Ben C34]

I'll just add I can't see how the belt knows how much power the engine makes.....

[lcxu105]

Don't want to invest hard earned cash and have a belt fail and destroy it all

[iruvyouskyrine]

Okay then I would buy the most expensive belt you can get, maybe get in contact with OS Giken and see what belt they used on their 26 strokers. Meanwhile everyone else will be over here using the inferior Dayco belt just fine.

[lcxu105]

Ok. That tells me what I wanted to know. The dayco belt is just gine than and thats what everyone is using.

Was speaking with a bloke the other day and he said that the top deck of the block needs a different finish for the cometic head gasket. Never used them before so don't know if this bloke was telling the truth or Tring to blow smoke up my arse.
