yeah a shorter final drive would be a good upgrade, and for <500 its pretty reasonable. i wish i could get a GTR. (either one) thanks for your input, it was of some help.

I don't know where you live but, I have a friend here in japan that exports skylines. He is currently shipping an R33 GTR built by TopSecret back to Florida. He does have a nice project car, an R32 GTR. The car needs some work but for $1500 it's a great start. I purchased my 1991 GTR for $3900. It had over $3000 in upgrades when I bought it, like HKS coilovers, NEOVA tires, MOMO steering wheel, strut tower braces, drilled/slotted rotors and rebuilt turbos. He can ship and do all the legalizing for about 10 grand. Not bad considering my 1991 GTR went for $45,000 when it was brand new. I sold my S-13 when I found out how cheap cars are over here. It would take 10 grand to get my s-13 to perform like my skyline. Don't get me wrong I still love the S chasis. I might even pick up an S-15 before I leave Japan. That's right S-15!

^see thats how it should be down in the States. but since im in Houston, TX its not really possible for me to get deals like that. you said he can "legalize" them, do you mean get them legally registered to own and show but not necessarily legal to drive on the streets due to saftey and smog regulations? ive heard alot of stories and horror stories of "legal" skylines in the US, or TX at least. and unless you pay in excess of 20k and buy two skylines, (one for safetey testing) it will never be legal. no matter what. due to the chassis reinforcement and safety issues. but oh yes given the chance to get and R33 GTR i wouldnt hesitate at all.

You can legally import and register 96-98 skylines as long as they go through an approved RI.

Okay here's a brief run down. The only reason 96-98 skylines are considered legal is because Motor-ex petitioned the NHTSA after being threatened by the Gov. Before that Motor-ex was grey importing skylines, that's why you see some R32 Skylines running about. Grey market importing is still legal, it's just that law makers have already past bills and regulations. It would take more money and court cost to pass more regulations. There are legit companies like Kaizo who has found the most legal way since Motor-ex to import. All in all it's still grey market. You name any car made in japan and it can be imported for under $12000, Tax, Tag and titled. If it was truly a safety issue do you really think a 1989 Yugo would out crash test a 1989 R32 GTR Skyline? Ive been researching this stuff for over five years and I've seen skylines imported in every way possible and not one person I know has been forced to export their car. Hell Paul Walker even has an R34 GTR.

Motorex only got the 96-98's approved by the nhtsa and were importing all the other R32 r34 skylines as 96-98's MY skylines. All in all only the 96-98's are federally legal. I think everyone has seen R32, R34's s15's etc on the street. There are various ways to get them registered but that doesn't mean they are legal.
The bottom line is the 96-98's are the only skylines on the nhtsa import list. The chance of the feds finding out is very small.

^yeah thats what i thought, only the R33's are pretty much "allowed" in the US now.

Not to offend anyone but let me put this in an easier perspective. I'm sure everyone has seen pontiac fiero Lambo kit cars and street legal fiber glass dune buggies. These cars are 100% street legal. Now, in terms of importing a car that does not have a drive train or unapproved glazing can be shipped legally, trust me it's on the NHTSA website. When the car is in this state it is considered auto parts. Now you go to your states DMV website and apply for a kit car title. Only so many per state are given out per year. Now you need a donor car like a wrecked 240sx with a clear title. Pretty much swap the vin tag or rivet the new one next to your BNR vin tag. In the case of the fiber glass dune buggies, they remove the VW Bug VIN off the center tunnel and then they rivet the VIN tag to the firewall of the kit body. You will need a Master certified ASE mech. to sign off on your DMV kit car application stating your new untouched unmodified skyline is road safe. The only down side is you may be limited to annual milage depending on your state, any where from 5,000 miles a year to 20,000 a year. But who's gonna use their GTR as a daily driver? That's grey as it gets and it's just as legal as the posser driving a Lambo kit car. The only difference is you might have a chance at beating a Lambo.

I don't think I would trust anybody from a company that got shut down by the FBI for extortion, atemted murder and fraud. That's like taking your kids to a Michael Jackson day care. The owner of RBmotoring also worked for Motorex. That was his R33 in the first fast and furious. He started importing and then shortly got out. I e-mailed him but got no response. All he does now is sell over priced JDM wheels to suckers. Have you checked out WWW.kaizoindustries.com? He charges an arm and a leg for shells. There's nothing illegal about what he is doing. You could do the same thing for a fraction of that price and still have everything to get it runnuing. What you guys do with this info is all on you. I thought I would be nice and tell you how to own a Skyline GTR.

alright well thanks for turning my thread into a how to import a skyline thread.

nah im j/k its all good. got some good info out of it, thanks for the input.

Okay I thought we gave you all the info you needed. I didn't open the can of worms, Maybe I bragged I little about owning a GTR I'm sorry for that. If I could give you one more bit of info, it would be how to save money on your RB rebuild. If you live near eastern Texas, there is a shop in Littlerock Ar. called Deep Freeze they cryo treat everything. If you are not familiar with the process check out their web site. There is no magic to this just pure science. For the price of a set of new forged pistons you can cryo treat your whole engine. This will increase the strength of you block and internals 10 fold. Peace!

Cryo tempering is a good option in addition to getting pistons and rods, but is no replacement. Cryo will NOT increase strength 10 fold. Maybe 10 %.

Being that RB motors are ballanced engines, unlike an I4 or V6 engines that are not ballanced, means when increasing redline you don't have much harmonics wise to worry about. Make sure all hardware is capable (head, block, pumps), engine breaths better, and turbo is matched correctly.

never heard of this process but thanks for the heads up, i'll look into it a lot more.

yeah thats good to hear. because i see alot of built motors for drift/drag/track that have heightened redlines like its not a real problem for them to do. of course everything will be correctly sized and tuned for it to all run like a real champ. thanks for your input!

Let me clarify my 10 fold statement. DEEP FREEZE guarantees a 150% increase in the products lifespan or your money back. I'm an AEROSPACE PROPULSION CRAFTSMAN in the UNITED STATES AIRFORCE and we use this process when building fighter jet engines. I don't know you heard but we are undefeated in fights to the death. And 150% is more than 10%. They charge $600 to treat your whole engine and I would throw your bearings in there also.

Don't be confused about balancing engines. All engines are balanced to a certain degree. Some are internally balanced and others external. Some use balance shafts and some use a combination of harmonic balancers and flywheels. The point is all engines are balanced, it's just the factory relies on bob weight balancing for stock applications. The performance world uses dynamic balancing, a way of going a step further by fine tunning or in other words reducing harmonics. DO NOT SKIM ON THIS PROCESS! By treating your block and internals you reduce the amount of block distortion, a real killer of high RPM engines. If you want me to I could go into deep details on building performance engines but a good machine shop could do the same. Make sure you have a shop with a great reputation and will answer all your questions with understandable answers. Texas has some of the best speed shops so please take full advantage.

150% greater lifespan does not mean 150% stronger. It's not a linear relationship between strength and product lifespan. Do some research, tensile strength (wear resistance) and dementional stability are not increased more than 20%, depending on metal application and previous thermal treatment. Not to mention 10 fold means exactly 1000%.

I'm not so sure you understand what cryo tempering does. It releaves stress inside the alloy. This is achieved because cryo treatment realigns the molicules inside the metal for a more uniform crystaline structure, therefore decreasing stress points where failure can occur.

Also I would be hesitant to temper bearings, as they are designed to wear so your crank and rods won't. I'm not 100% on that tho, as the increase in tensile strength of the journals may negate the negative effect of strengthening bearings.

FYI most applications will see 200-400% increase in lifespan.
