I hate skylines. It's so awesome for me to hear from the owner of one that he's rather have a vette, and is planning on selling his for a miata.

It's funny you say that, I had one while I lived in Japan and that was my exact experience. Overrated and overpriced. It was a decent car, and fun to drive, but not nearly worth the hype.

My thoughts exactly, If you can pick one up for a reasonable price like in japan where they will only run you a few grand then they are a great deal, I just wouldn't spend the money on one in the states.

But they were heavy and far too slow in stock form by today's standards. We are living in the time of a horsepower and technology renaissance that shades our view of the past. The typical measuring stick on the street in America in the late eighties and early nineties was a 215 advertised horsepower limp dishrag chassis called a 5.0 Mustang. That's about 185whp.

Once a GT-R gets above 500whp, they really make use of the AWD system and are not going to be able to adequately put the power down without it. I've driven a 1991 GT-R many, many spirited miles (belongs to my closest running buddy) and been a passenger for thousands of miles in one. It is one of only a couple of Motorex R32s that were completed by them and federally certified 50-state legal. He brought it back from Okinawa, Japan. It is heavily modified and at 733rwhp it is a handful at times on street rubber. I helped him tear the engine down recently in preparation for moar powah. Those damn things are hard to work on...

Very, true. Mine is a gtst and therefore has the RB25 lump (and it's inherent problems) in it And like I've said before, it is fun to drive and I'll admit they were a great car in their time. And well worthy of the reputation they had in that time. But as you said, they just don't cut it by today's standards (although the RB26 comes much closer than the 25). Yet they continue to get hyped like they are modern supercars. Yeah they are a blast to drive and have plenty of potential, I just think they fall a little short of the hype. Same with the supras, great cars, just not the "be all end all" car that some like to portray them as. And you are absolutely correct, they are a real PITA to work on, Hoses everywhere and no room to reach anything. I can only imagine it is worse with two turbos and an awd system in the way.

Your buddy would not happen to be named Matty and currently living in Germany would he? Matty helped me find an engine when mine needed replaced, he also has a motorex r32 back in the states putting down numbers very close to that.

"The typical measuring stick on the street in America in the late eighties and early nineties was a 215 advertised horsepower limp dishrag chassis called a 5.0 Mustang." ROFL so very very true, we were really selling ourselves short back then.

Don't get me wrong, it's a fun car. It's just not as great as some people would make it out to be. Mine is an R33 GTS25T which only makes roughly 200rwhp in stock form, it weighs over 3000lbs and drinks gas like a frat boy drinks cheap beer. I just think I can have more fun with a miata for a LOT less money. Not really one to care about the car as a status symbol, I just want something fun to drive.

All good choices, I really like the speed3's, great sleepers. A car that looks like that just shouldn't be that fast.

I see brain already mentioned T25 off a SR20, but that would be a good starting point if you're on a budget. You can always throw on a bigger/garrett later. Or start with a cheap china turbo for starters. anyways my advice is pretty much in line with everyone else

diypnp
460/550cc rx7 injectors
fm/begi cast manifold (used if budget)
matching downpipe/exhaust whatever you can find. if you want to get new exhaust stuff, including manifold, i highly recommend ARTech on MT.net
cxracing/godspeed intercooler (or whatever ebay is fine)

my old setup, artech mani/exhaust (3"), tiny cxracing intercoooler, 550cc rx7 injectors, diypnp (made by brain), gt2560 @ 16psi (i didnt want to run this much, but i had boost creep issues....downpipe design was the cause), 14psi should have been right around 250, which is what i originally planned. 99 stock motor.

Thanks for the advice, I really like how you included specific brand names, this will help in my search for parts. Since I am only shooting for 200 RWHP to start with, I believe the parts you mentioned should be very suitable for a conservative tune and still have the ability to push 200 to the rear wheels. Therefore leaving me with a reliable yet exciting to drive roadster, with years of use ahead of me. Thanks a lot.
