Hey Guys,

I am getting my RB26DETT 98 Silvia back tomorrow after being shipped halfway across the country....

Here's the pics and vids.... www.undergroundmotorsports.com

I am a little concerned as the sound of the motor in the vids sounds a little off...

The motor has cams and some head work....

I don't have any experience with the GTR's, so this is the first GTR motor I've heard...

Something sounds a little off to me... But the shop that performed the work feels confident everything is cool....

Opinions are greatly appreciated...

I had a listen, the only one where you can here it is when it drives off in the car park, it sounded ok to me :D The shots of it running its hard to hear the motor clearly

No smoke coming out of it, thats always a good sign

Just keep a eye on the knock level on the PFC hand controller :)

Firstly Underground. Excellent choice mate :D

In the second vid I can hear what you're talking about. The car seems to have a lot of trouble idling stably. Could be a tuning problem, or fuel delivery problem (doubtful as it clears up when he revs it), dirty/incorrect spark plugs or an air leak. When you get the car I would whack a fresh set of plugs in it (ensuring they are gapped properly) check all the inlet plumbing (from the MAFs to the turbos, turbos to IC, IC to plenum - everything). See how that goes. The engine seems ok though, think of it as more of an ancillary problem.

Enjoy :)

My car did the same with the PFC plugged,when at idle it would go up and down always hunting.What I did was go into the Idle settings and bumped the second idle setting up to 1270 I think.Have a go at playing with different settings,you wont do no harm.

Nice beast to :aroused:

On the PFC put more fuel into it, at idle and see what happens.

I had a similar problem with a Rb25, upped the fuel intake at idle and ran heaps smoother. Also is it idling at 750 - 800 or lower? Also is your exhaust straight through? With a hollow cat ? and how many resonators do you have on your exhaust system ?

What plugs do I buy? What part #? Obviously nobody here in the states is gonna know RB series part numbers?

Also, what should I gap them at? Or do they come bolt-in from the package?
