I Need Help!

[Bdon0806]

Hello there,

I am new to this forum, even to the Skyline. I just bought a 95 gts-t with an rb26 conversion. I live in Italy, but the car came from the UK. I drive the car and it just does not feel right. I wanted to know if anybody has doen this engine swap and what should be in the car and what shouldnt.

As I drive the car, it makes a wierd sound, I hear the turbos kicking in, however, they kick in at about 3000rpm, then the rpms shoot from about 4800 all the way to 7000 but no power or torque is being felt, its as if i am stepping on the clutch, boost goes to about 1.6bar, I am reaching 110 km in fifth gear since I feel that if I dont shift, the engine will blow, I had a turbo civic, so I know somewhat how the car should be feeling when the boost kicks in. Just this car does not feel like it has power.

Also, the engine looks like it is missing components, and there are various cables that are not connected to anything. I will post some pics of the engine bay so that you guys with alot more knowledge of this car can help me out. Please, I need help and there is no mechanic here that know about the skylines.

lol. Sure you don't have a dead clutch? It rather sounds like it is slipping. The weird sound could also be the clutch. Dunno, i'm not really an expert, but i'm definately not a fan of conversions like that.

Interesting to see the pics though!

Definately sounds like a slipping clutch... time to rip it out and get it replaced =)

Here are the pics of my engine. One is the engine with open wires, another is of a hole or an intake pipe that has nothing attached to it elow one of the air intakes to the turbos.

The other sound it makes is when the turbos kickin, it sounds like gears grinding when I shift gears and the boost releases pressure, I dont believe that I have a bov and an external waste gate. Do you guys recommend this upgrade?

Thanks for your help.

THe 2 plugs are for the front and rear oxygen sensors for an rb26. the pipe i assume is for the standard BOVs which have probably been replaced with aftermarket, have a look along the intercooler piping for new BOVs.

Internal wastegate is fine for standard turbos.

If the 02 sensors are not connected you might have an aftermarket computer that doesnt use them (have a look in the passenger footwell). Or if you have the standard computer there might be an issue with the wiring and they left the sensors off.

Either way without 02 sensors you will get very poor fuel economy around town.

If the clutch is going out, what kind of clutch should I replace it with? I hae the rb26 engine with an rb25 clutch and tranny

Some one had mentioned to me that a double or triple clutch would suffice using the same tranny. Is this true.

Here is a pic of my car

thanks

1.6bar is pretty high, so i'd imagine that it has a front-mount, new turbo, and so on... With that sort of power, you'd probably have to go for a clutch with very high clamping pressure. The twin and triple plate designs usually have a very strong pressure plate, so it could be the way to go. The downside is that these clutches are usually button-type (brass or ceramic). If you go that way, and it's your daily driver, see if you can source a kit that is a CUSHIONED button clutch. It gives the feel of a non-button, but mechanically it is on or off like a button clutch.

I finally got to drive the car for some distance, pushed the car somewhat and drove the car around some good curves here in Italy pretty fast. When I arrived to my destination, I herd a weird noise comming from underneath of the car. Close to the rear wheels, it sounded like a high pitched noise constantly on It did not turn off until the car turned off. I have heard it before when I turn it on, however, this time it sounded louder. What could it be? Thank you for your help on the clutch issue, I have ordered a nismo twin plate clutch. Hopefully I should feel the power then..

It sounds like your car has more problems then its worth...
