Hi guys does anyone here have any experience regarding weight reduction on the 25gt four version?
How much weight can the car lose? is it possible to lose around 100-200kg ?

instead of chasing hp gain and wasting a crap load of money wouldn't it not be better if i just remove useless crap off the car and give it a better power to weight ratio.

could you guys list me down what can be removed and how much kg roughly they are.

The only things I can think off is the following things not sure how many kg each item is as well..

back seats ?

spare tire ?

sound deadening ?

air con ?

what else can be removed that will still keep the car street legal?

Back on topic, some GTT weight reduction estimates from here: http://www.skylineowners.com/forum/21-tuning-technical-questions/172043-r34-gtt-weight-reduction-loss.html

5kg Sound Deadening

5kg carpets
20kg race seats (providing you remove front & back, all the seat belts and tensioners then replace them with light side mount rails and fibre/Kevlar shell.
20kg air con gubbins including the matrix behind the dash
7kg sound system – 4 speakers, sterio, amp boxes etc
7kg Hicas removal. Providing you just swap it out for a locking collar
15kg light weight exhaust. Yep, probably – if you lose all the silencers, cat etc
8kg coilovers – depending on what you get, you’ll probably lose 2kg a corner.
You can also lose weight through
- Bonnet
- Boot lid
- Wings
- Wheels & tyres
- Doors
- Strip down the loom
- Bumper braces
- Headlights (if it’s just a daytime track car, you don’t need them)
- Glass (replace with Lexan for the rear ¼, side and rear window,
- Cast manifold for tubular (will save you a bit)
- Replace electronic wing mirrors with static
- Remove electric window motors
Remember you need to fit a cage which will put weight BACK INTO the car, as will corner weighting.

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
