RB26 head on RB30 block

[93RPS13]

Hi has anyone done this with the twin turbos also can anyone gave me some figures of the power and torque if possible? Thanks

[meggala]

heaps if built right over 700-800hp is achievable with the right components

[93RPS13]

what about stock?

[meggala]

no stock around 3-400 hp the rb30 block is pretty=weak stock

[93RPS13]

thanks for the 4 sec reply lol

meggala, what do you have to do to the block to strengthen it? The idea of an RB30 bottom end on a RB26 head really appeals to me, so this has made me a little concerned.

Have you got any idea what are the VL boys doing to protect their engines when they pull off those 400 - 500rwkw numbers?

Cheers,

Michael

93RPS13,

You're not located in Boston are you?

[93RPS13]

ya 20 min out...Bean town that right, just doing research now for the project when i get money i am going to do it i love this thought right here RB30DETT in a S13 and dont tell me i cant because there a company that can help, RB26DETT has been done in a S13 the only difference is that the RB30 block is alittle higher:)

i have never seen a skyline in boston before also are you in anywhere with X-Crew?

[meggala]

the block is fine you just need better rods and pistons. stock cranks should be fine with treatment. the main issue with them is they dont have oil squirters to cool the pistons like the rb 20/25 26

dont OS Giken make a fully built and prepped 3L bottom end for the RB26 head? used for drag. im sure its not cheap though, but i think its rated to take up to 1200hp!

just pop one of those in there

93RPS13, I'm an Aussie living in Boston. My Skyline is at home collecting dust. If I could have brought it over I would have, but it's damn near impossible to get anything into this country.

I have to say the thought of a RB30DETT sounds pretty damn cool. I'd do that to my car if I had the cash. I've seen some pics of an RB26DETT in a 180SX body and the bonnet couldn't close. I'd say you'll have some slight issues with the RB30, but nothing that can't be worked around. It will have to be the fastest S13 in MA once you're done though. Actually, I haven't seen any decent cars around here. What's the deal with the car scene over here? Who's this X-Crew you mentioned? I'm missing my car so I'd like to see what the local cars are like. I'm in Brookline btw.

Cheers,

Michael

brookline damn the rich part of town, i seen a really nice blue S14 with S15 front end conversion and the engine was a KA-T, X-Crew is like a car club aka Boston Imports, also if you get this in time there is a car show today, Hot Imports Night, in dorchester, Bay side expo center this is where is at, i cant go because i have to save my money for the engine and other stuff

[93RPS13]

what flywheel does the RB30 take with a RB25DET trans?

[dojobi]

Damn, I can't believe I missed this post. I could have gone to the show.

It's not bad here in Brookline, but there's no way I'd be staying here if I was paying the rent. It's absolutely ridiculous. I can't imagine what it would be like in the Back Bay area or downtown.

Oh, and a free bump for your flywheel question

[Guest mort]

When using rb25det gearbox behind rb30 use the rb25 flywheel

[meggala]

hey mic you can actually get a skyline into the country but you have to re export it or destroy it after 1 year its worth looking into the law ids pretty clear but dontask me which law

cheers

Are you serious? That'd be awesome. I'll check it out but I've only got another 5 months or so here. If it makes sense financially then I'll do it.

I could always import it then have it get "stolen" and then sell it to someone j/k

I found this in a doc file from the US gov. There's a heap of info in it. You can get it here:

Anyway, here's the bit that interested me -

Nonresidents may import an automobile or motorcycle and its usual equipment free of duty for a temporary stay to take part in races or other specific purposes. However, prior written approval from the EPA is required and such approval is granted only to those racing vehicles that EPA deems not capable of safe or practical use on streets and highways. If the contests are for other than money purposes, the vehicle may be admitted for 90 days without formal entry or bond if the Customs officer is satisfied as to the importer’s identify and good faith. The vehicle becomes subject to forfeiture if it is not exported or if a bond is not given within 90 days of its importation. Prior written approval must be obtained from DOT. A vehicle may be temporarily imported for testing, demonstration, or racing purposes. A vehicle may be permanently imported for show or display. Written approval from DOT is required and should be obtained before the vehicle is exported from the foreign country to the U.S. Information on how to import a vehicle under show or display is available at DOT’s NHTSA Web site at www.NHTSA.dot.gov/cars/rules/import. A vehicle permanently imported for show and display must comply with all U.S. emission requirements as well, and in general must be imported through an EPA-authorized ICI for modification and testing. EPA will not allow the vehicle to be released to its owner until ICI work is complete.

I suppose I could just call it a show car and that would work. That could even be true considering the rarity of Skylines here.

EDIT: I read more about it, and there's pretty well no chance it would qualify as a show car. Reasons are here http://www.nhtsa.dot.gov/cars/rules/import...osd05-2003.html
