.63 or .82 gt3071 with e85 and plenty of boost should come about as close as your gonna get to your goal.

or if your happy to go crazy with boost (and not worried about turbo life and heat etc) you could try a large rear housed gtx28 of some sort

[NYTSKY]

Fuel economy and E85 dont mix

I did 180kms on the weekend and used 40L lol

I did actually have teh GTX28's in mind for the 1J, cant help but think the turbine side will be too small for the 3L

But I am now looking at those options, Cheers

just kicking around and found this info and thought i would share

the dayco 94407 timing belt used for the rb30det hybrid builds is from a Mazda 323 1.7ltr PN diesel 85-93 that makes a whopping 57hp

[N1GTR]

So you found one in stock?

[XKLABA]

nah,justjap have the 150 tooth belt I want to use the 152 tooth, it's ok greg has a spare he can use to line up the idler wheel

[N1GTR]

As long as it's getting there - that's the main thing.

Seems as if Sutton is on the cards then hey - you'll love the big stroke engine compared to the 32's engine back to back

[XKLABA]

yeah now Gregs got his hands on it it will get moving.

god I hope so, been waiting for Sutton

just hope the turbs aren't going to negate the benefit of the stroke

ps thank for the help the other night

[N1GTR]

Anytime! Feel free call whenever.

You're putting the same cams and turbos on that it had when I saw it last?

[XKLABA]

yeah still going with the same set up I was going with when we talked at texi

some guys selling a new rb25-30 in the for sale section for good price

[Simon-S14]

quick question... but the RB30 exstra deck height is above the water pump yeah? So the position of my engine fan shouldnt change after fitting a 30 block compared to 25?

[JonnoHR31]

correct

[Black R32]

I have no updates. But 3.0L related

Has anyone seen either a td06-20g or any other smallish turbo on a twincam 30? I have seen a few gt3076's done

Or if you had a choice the best super responsive circa 300rwkw turbo

I'm thinking I want 20+ psi at 3000 rpm and mega midrange

I'm planning on slapping together a 25/30 for round 2 on the 14th of July and i'll be running a TD06-20g High mount.....

I shall inform you of how it goes!

[Simon-S14]

what timing belt do i use for a 26/30 combo if i use the two tensioner in stock location method? anyone got a dayco part number?

[JonnoHR31]

You can use this one:

http://justjap.com/store/product.php?productid=17872&cat=&page=1

But ideally you want one a tiny bit shorter as once you deck the head and block and the belt stretches a bit it gets real close....

Much better off relocating the drivers side tensioner, just wait until you have a belt so you can figure out exactly where to put it as the dimensions in the PDF don't always work.

[Simon-S14]

yeah i might end up doing that.

does anyone have measurements other then the PDF that are guarenteed to work

[JonnoHR31]

I used the measurements in the PDF with the above belt and it didnt work, couldn't get the belt on but it was close. Probably just needs to be moved to the right 5-10mm. No set measurements are garunteed to be perfect as theres too many variables.

[Gerg_R31]

here is what i do at work;

i grind the head & block

i put the cams in

i put the crank in

i put a thick rag on the deck

i put the head on

i put on all the timing gear

i put bearing blue on bottom of stud,

i then line up tensioner to where its best suited

i then drill and tap the M10x 1.5 thread

Started getting things together to get my dirty thirty project started. Funds are an issue for me so may take longer than u guys lol. But I don't wanna take short cuts so a bit longer without will be worth the wait. Picked up a complete rb30 out of an r31 couple weeks ago for a hundred bucks and a case. Planning on getting an engine stand soon and stripping it down. Then finding a r33 25 head as I want it built out of car to be slotted into daily when complete. So much info! Been reading for the past 2 weeks and printing shit off. Gerg, looking at bringing block, head and other bits and pieces down down to you if ur in Moorebank cause its around the corner from me. A while off though lol.
