Hi All.
I'm thinking of upgrading my standard GTR to Stage 4.25 and am wondering what peoples opinion is who have done this?
Were your reactions like OMG this is amazing performance or it doesnt feel as powerful as I thought it would be?
Personally I've never thought my R35 is that quick despite everyone I take for a ride in it saying that it is amazing. I think that having various 1000cc bikes in the past has made me a little immune to the feeling of acceleration and speed!
Any opinions on this will.be greatly received. Cheers.

Personally I don't think stock GT-Rs are very quick. If you go straight to 4.25 you will be like OMG that's good. But tbh even just a stage 1 tune will make the car even better. You just get a bit more torque and a lot more drama with the rest of the stuff.

Thanks gtr mart. That's what I was hoping someone was gonna say. My car is booked in to Litchfields for end of Jan to have the 4.25 upgrade done. Doing it then to tie in with servicing and MOT. I'm sticking with the stock titanium rear silencer as I dont want the car to be too loud so I'm guessing I'll lose a couple of bhp because of this. Just cant wait now ***x1f642;

Firstly congratulations, if you're going to go for stage 4.25 then request Litchfields to set it up on the road for you, you can jump in the car with Ian or Dan depending on who maps it and road map it which is better in my opinion. Ask them to set it up for your requirement meaning like do you want it for drag, track or mid range power then they will dial the torque in accordingly. I personally have my cars set up for quick off the mark because i don't do track days or motorway journeys where im interested in top end power.

Thanks for your comment. Every days a learning day. I didn't realise I could have the torque set up for my own preference. I've done a track day and would love to do more but the reality is I'll do a lot more drag days so will ask for the torque to be set accordingly. I've done a 10.921 quarter mile run in standard form, any idea what I can expect with the tune?

10.9 in a stock car thats really good, id say 4.25 with everything rite Inc tyres and head wind id say 10.6ish, on the drag strip there isn't a great deal of difference untill you go to stage 5, stage 4.25 you'll notice more in the midrange power.

Thanks I was really chuffed with the 10.9 but I try to think of every little detail to get the best out of the car. 10.6 would be great after the tune.

I bought mine with a Stage 1, so I can***8217;t compare to stock. But I was very happy with it as GTR-Mart says, and I had no desire to go further. But a new Bell housing meant the downpipes needed to come off and that was the decision time to go to 4.25 with the decat downpipes and the rest of the mods. The noise, the torque and even the manic top end are addictive. But I would still wait til I needed a Bell housing to go to 4.25, and enjoy a Stage 1 with a Y-pipe until then.

Takamo. Do you know if I will be able to customise the launch settings when upgraded? Do I need an Ecutek module for this?

Yes, you will be able to set boost off the line and torque setting through the ecuteck dongle

Many thanks for the reply. That's great news, plenty for me to play with before the next drag event.

124.10mph terminal speed.
There has been an 800bhp GTR at the drag a couple of times that has been 0.4sec quicker than me so I realise that upgrading isn't gonna change the times by a great deal however when you watch a car pull 0.4sec out of you it looks mighty impressive.

That really is a small improvement for a big investment.
Maybe the other car needs a tune up as that really doesnt justify the costs involved.


When you say your car is standard, is it still the original exhaust and air filters??

My car has a Milltek Non Res Y pipe and K&N drop in filters but in Litchfields words - there will be no performance gain without a remap

As I understand the earlier cars performed better after a stage 1 map but the newer models barely improved?

What year is your one?
