Well my car just dynoed 212kw @ 18psi.

My mods include:

Microtech LT-8

Custom Frontmount

3.5 inch dump to cat 3 inch for the rest

Hyflow T3/4

h/d Clutch

Vl pusher pump as well as standard intank

Standard air box

Well i don't know what everyone else thinks but this seams a little low for the modifications. I though atleast 257kw because have beaten a certain silva with a rb20 before.

The dyno was not in shootout mode and had a ramp rate of 100

Did you dyno it with the bonnet down?

Thats the best way to get a more realistic figure. It is always a lower figure too.

I wouldn't worry about the figure if it was an improvement.

The real measurement is beating that 'certain silvia' and doing some quick times around your favorite circuit or drag strip.

Stop getting all hyped about the dyno figure.

It's a peice of paper, just like toilet paper its only fit to wipe your ass on if its not being used to help tune a car.

So what if the silvias got a better dyno readout. Scan yours into the computer and change it with photoshop to read 1000rwkw, then you can beat him at the races AND in a dyno paper stand off!

Yes you can say i'm a little focused on the dyno readout, I guess 212kw is not enough. The tune on the car was pretty S&*t, as soon as i gave it a boot full it detonated the loudest i have ever heard it. Sooo in 2 weeks it will be going back on the dyno, the same one as the rb silvia.

I'll let everyone know how it goes!

:D

Hi sik32, is this an RB20DET? No adjustable cam pulleys? No injector upgrade? No adjustable fuel pressure regulator? No internal mods? Standard camshafts? No pod?

If it's a roller dyno (not hub) 212 rwkw is 360 bhp, that's pretty good for an RB20DET with the mods you have listed. I'm surprised it didn't run out of injector capacity.

I sort of agree with the other guys, except I reckon the dyno might be a bit optimistic.

PS; let us know the dyno shop that the Silvia runs on, I want to take my car there and get a good bit of paper to wipe my butt on as well.

hey sik32,

I'm too am running a LT-8 on my recently purchased GTS-4.

Just wondering how you find the driveability of it in your RB20?

How's the economy if your just cruising along in 5th gear?

I don't think they have closed-loop cruise mode. So they don't use the oxy sensor, do they?

What about initial start-up?

I know the LT-8 doesn't use the idle stepper valve. (the thing on the end of the plenum) So do you have some sort of air by-pass valve to compensate for the greater amount of fuel at start-up?

I'm just asking cos I find that mine never starts cleanly especially after I haven't driven it for a day or so. Sometimes it even seems like it wants to stall itself cos of the lack of air (revs drop below 500)

As far as the economy on my car, it pretty bad considering that I hardly ever boost it around town. and I spend alot of time cruising in 5th gear. something like 350km to a tank:(

I haven't had a chance to dyno it yet but hopefully will in a few weeks.

anything you can enlighten me on?:P

ok Interloper, First of all I find Microtech a great computer if you are on a budget. Drivability is fine, as it drives like the standard computer, but there is a few things that dislike about my Microtech. Cold starts, the car sometimes stalls on the first turn of the key and will not idle properly until the car has warmed up properly. This seems to be a problem that most cars with microtech have.

Fuel ecomomy, well that went out the window along with my standard computer. Microtech is Very bad on fuel, this also may be caused by the tuning as I like it too be a little fat. Even when i'm off boost and on the highway it still sucks fuel like no tomorrow.

Yes approx 350km. If i could do it all over again i would chose apexi or motec because of money i have wasted on fuel i could have afforded either of these. No Joke

Good luck with it all:D

Ps thanks for the toilet jokes guys!!!!!!!:bahaha:

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
