Greetings,

I am the proud owner of my R35 GTrrrr, and brings a smile to my face everytime I hit the pedal to the metal. However I would like to increase the BHP as much as possible without an ECU remap, as WarrantyDirect have told me this would cause my cover to be null and void.

So, what I have done is introduced a full Miltek Titanium exhaust system thanks to ValetMagic, giving me circa 20BHP additionally sounding awesome.
Is anyone in the same boat, looking to increase BHP and wanting to know the options without ECU remapping, perhaps cooling intakes, filters will that help ?

Any hints towards approved mods within my Warrantly clause would be much appreciated :)

Best regards, Kamil

To be honest, I'm not sure there is much more you can do. Even induction kits need a map I think (replacement filters should be okay but not really bhp gain). Downpipes might give you an extra 10bhp but then again, I think you need a map. Dump valve....no bhp though.

Sticky tyres and a driving course will allow you to use the power on the road better. Weight saving (whilst not cheap) will improve speed, or get a refund from Warranty direct, take it to Litchfields to do a Stage 4 and get his warranty :chuckle:

Sorry, thats not what you wanted to hear :rolleyes:

Haha, sticky tyres and a driving course :)
Yes according to another member it seems a remap, is recommended to get the best out of the car, and the people to cover this would be Litchfields. Will need to see what their costings options are from Stage 1, 2, etc....

All on their website and you have the exhaust already that will make stage 2 cheaper. You can buy their warranty for £1000 if that's important to you.

Appreciate your reply Adamantium, as my extended warranty from dealer has now moved across to Warrantdirect this week, I'll have to look at the Stage 2 costs and perhaps either cancel warranty and transfer, or leave it for another 12months. Like most people have said, a remap should take advantage of recent mods :)

wouldnt worry graham, exhaust with remap causes it run rich. In the past greater volumetric effciency would cause it to run lean but int he case of the gtr, it just goes over to a part of the fuel map that is rich. It's quite safe though inefficient and not allowing you to really take full advantage of the greater flow.

Still wouldnt feel right, besides thats where the best gains are made

I would definately see if you can get a refund on your warranty direct warranty and just go for the remap and litcho stage II with their warranty. To be honest it's a safe(ish) mod. No reports of a litchfield stage II ever going bang and they've done literally hundreds of them. My only concern would be a transmission issue if not treated properly (i.e not warming up tranny fluid before hard use, repeated launches etc) but if you get a litcho warrenty that would be covered anyway. I'm still weighing up whether to get an extended warranty when mine runs out next year. These cars are pretty solid and i just think it may be money down the drain.

Mate a tranny failure during launch would not be covered by litchfields warranty hence why i didnt take one out!! an engine failure or bellhousing will be thats about it!! the headunit as you probably are aware has been extended to five years and the headlights arent in the cover, so i figured i wont take out the warranty at a grand per year the engines are pretty much bullet proof the bellhousing wil cost circa 700 to fix from litchfields anyway,
I found all this out when i was there for service and stage 2 and lc5 software
i asked about launch control and is it safe to do so and at that point Iain informed me if the transmission breaks when launching then it wont be covered which in all fairness i totally understand where he's coming from as
there are likely to be people who will just be launching all the time and the odds are the tranny might get damaged, so i decided not to ever launch the car and thats it, so i guess it could well be money down the drain as you said as i only do 3-4kmiles a year anyway, the gear changes are so much better now with the new software though:thumbsup:

makes sense John.

I tend to agree with you and it's the reason why I effectively stuck two fingers up at the idea of my own warranty.

Engine is bullet proof, which is why I'm not worried about it.

In my case the gearbox was actually covered during launching since it's an my11, but now that it has circlips, I doubt they'd honour that, but then, now that it has circlips, I don't expect it would fail if I was bothering to launch the thing.

My ultimate advice is that the OP should stop worrying about the warranty. The only risk really is the transmission, which isn't covered anyway, and is no more than £1500 to fix should it go wrong anyway.

Ask yourself a question, how many people have had gearbox failures, and of those, how many actually needed the box replaced as nissan do because they can't fix them?

Your right Adam people should stop worrying about the warranty, at the end of the day it is a very reliable car, we are all aware of any issues as the car has been around long enough, in my case i dont track the car and drive it with care
as i have already said i dont do much mileage and odds are low.
If i save a grand per year having no warranty and no problems then maybe that extra cash can go towards more mods!! :chuckle:

Well I've been recommended a COBB stage 2 upgrade, so I researched the web and Youtube looked very impressive, extra 60bhp remap and using the full Titanium Miltek exhaust surely will not break it's back, hopefully just enhance the performance and reponse times, not sure if Litchfields would cover that as they have their own ECUTek I believe, think I'll call them also WarrantyDirect and see if they will refund me as the warranty only kicked in this week :)

I htought the Miltek exhausts were all staniless steel, save for the option of titanium tips. There's really very little to choose between the Cobb and Ecutek options. You'll find probably an equal number of supporters for each and very few problems at satge 2 level, which is where I'm at (Ecutek through Litchfields) and very pleased too.

Yes I believe you are quite right, believe majority of it is stainless steel and the rear end titanium, either way feel a difference in performance and sound :)
