Heya, I'm a new Skyline owner, and I was hoping to get some direction as to where I ought to look for decent turbo kits. I bought a 1994 R32 GTS 5/MT with a RB20-DE engine. As is it's great; even moreso since my previous car was a 1996 Saturn SL2. I can't help but desire a little more power, so any suggestions as to where I can get started would be great.

Thanks in advance (and my apologies for starting off with such a noobish thread).

Info:

Location: Japan (Niigata-ken)
Budget: $2500-3000
Desired Result: Moderately improved acceleration

please reply to my japan thread if possible, okay for turbo you shouldn't really go for it with a rb20-de because you might need to mod the bottom end(e.g. piston's,conrod's), you might need a better fuel pump also, and a intercooler is a necessity if you're looking for some 350-400hp, anyway's you're obvious choices are hks turbo, the TO series, or a hks 2835r, or why not a r34 gt or gtr turbo, it's a t3 based turbo good for about 400hp, you could probably find it in a jap. junkyard. :smile:

I really am not shooting for extreme hp since I'm not a racer. I just want to do something simple and as non-invasive as possible, mostly because I know I can't afford to go all-out on the car, much as I want to.

BTW- where is your Japan thread?

in the skyline general discussion forum.up top, do you see it? :smokin:

Posted there.

What I really need out of this thread, however, are specifics. I'm a complete novice when it comes to sports cars, and my knowledge of ordinary cars is pretty limited as well. Perhaps the best thing to have would be links to websites that sell complete kits (and that ship to Japan).

Thanks. :)

thank's for the reply, you mean located in japan, i know that hks, trust(greddy), mines, nismo, bee*r racing, hakimoto, and various other turbo supplier's are located in japan.

First you can not simply slap a turbo on the RB20DE engine and all that into a GTS. The entire engine managment system is different, along with the booster system for the brakes!.
Your car requires vaccume for the brakes to operate properly, where as if you are on boost you have pressure not vaccume.

Ok with that aside, lets look at what is required to do what you want.

The engine is a high compression. There for you have to either figure a way out to drop the compression ratio down, IE a 1.2mm metal head gasket or different pistons.

Next the heads are simular but not the same. The DE has smaller ports, not much but they are smaller. Also the cam profile is not really compatale. They will work but turbo'ed cars do not like large amounts of cam lobe overlap.

You're injectors have to be replace with large ones, and also as mentioned the fuel pump needs replacing to a high volumne one.

Now you have to get the exhaust manifold and turbo. An RB20DET factory one would be fine, then add some sort of intercooler.

Lastly you are looking at a major expense in the engine management system, unless you are able to score a factory GTS-t one. This is not an easy find unless you live in a country where there are plenty to pick from at a wreckers or tuners. If you go aftermarket it will need to be tuned.

At the end of the day you are better off getting a second hand RB20DET motor and doing the other little bits plus the ecu.

Thanks for the mini-guide. I live in Japan, so I think the chances of finding a new engine are pretty good. If I decide to do it, I'll probably use that route since it seems a lot simpler.

yeah i think so too, but razor what about the labour, he's a novice if im correct and he will most likely not do the swap himself. :)

If you live in Japan then it would be even easier to sell the GTS and buy a GTS-t.

It solves all the hassels of finding the parts, and doing the work, and it also gets you suspension and brakes better suited to the increase in power.
You also dont have to worry about the Japanese modfied vechile certifcation process, which Iv heard can be quite strict.

And at the end of the day it would probobly cost less, and you would not be with out a car for the time the work was being carried out, which could be anywhere from a week to a month.

Hey how much did you spend on the GTS?

You would have a much eaiser time just to go and get a GTS-T.

I got a GTS-T and it only cost me around 2 grand;214,000 Yen
