Well sounds like you have it all sorted out...looks as though everyone that has bought a rear section has wasted a lot of money. Might see a few in the for sale section after this thread.

I hope so!! I do want one, but for the sound

but waiting till after the downpipes...

I think it's gunna be the stage 1 by the sound of things

Anders_R35 · 13th May 2012, 08:27 PM

I'd agree with Graham on this one, I've got an oem rear section on mine and made 620bhp and about the same torque (I've got downpipes and intakes too).

I recon you can acheive about the same power on stock turbos with downpipes/y-pipe and stock rear section or oem downpipes with aftermarket y-pipe and rear section.

Edited to add, here's David Yu's dyno which is very similar power and torque to my result. David runs Cobb, oem downpipes, intakes, Akrapovic Evo exhaust.

Same as me and about what I expected (panels, y pipe and race rom)

The biggest jump will be stage 1 definitely..go with that and when you get used to it..go straight for a stage 4

I think a stage 1 really brings the car alive

barry P. · 13th May 2012, 09:34 PM

Mine made exactly 600 bhp with a RC Developments exhaust system ,which includes a Y pipe, on an Ecutek remap but my max boost is only 1.15 bar on the race rom. I've just bought a set of Forge intake pipes from Litchfields and a set of Bosch 850cc injectors, going back up to TRL for another map to see what it will produce with these mods.

Takamo · 13th May 2012, 10:30 PM

I'm really glad I asked the question now because I'm not the only one that felt that stage 2 was not worth it, and to be honest I thought about it that OEM exhaust system no one really buys them used and that will just sit around for years to come so I felt that would also be a waste. I think I'll go for the stage 1 and the gearbox software upgrade and see how it goes from There

grahamc · 14th May 2012, 07:19 AM

Stage 1 is brilliant. After that think about what you want from the car etc and then decide. Stage 1-4 would probably be the best bet! I like the sound of that

Litchfield · 14th May 2012, 07:59 AM

We like to under quote our BHP claims as this insures happy customers

There is a step change between Stage 1 and Stage 2. Making headline numbers is the easy bit as we have had over 600bhp on a completely standard car but tempertures and the effort the engine has to go through is reduced with the addition of an exhaust and intakes etc. In over 400 upgrades we have had no failures which is down to our careful testing and mapping

Our original GTRs were fully intrumented so we know exactly what the internal tempertures were on circuit and at very high speed. Many of the map differences are sutble so for example our Stage 2 boost map profiles are different whether we use the Milltek 76mm or 90mm as this change will effect how the turbos respond even at Stage 2 power levels.

Which ever route you take I'm sure you'll be pleased with the performance

Regards

Iain

I have no doubt about your level of skill or honesty because I've spoken to you and made my judgement that your a sound and honest chappy, but it's just I don't plan on any further upgrades because I think 600 or close to 600 is going to be plenty for what I need it for so I'm just wondering if having the extra 20bhp and sound change is really worth it to me, don't get me wrong I'm sure it's worth it for someone who is planning may upgrades later. I'll call you and have a chat to ya cheers for taking your time to explain

Takamo · 14th May 2012, 10:16 AM

All sorted and decided just can't wait now to get it done

Adamantium · 14th May 2012, 10:48 AM

decided what?

Takamo · 14th May 2012, 02:19 PM

I've decided..........wait for it.....stage4...........na stage 2 really

grahamc · 14th May 2012, 02:19 PM

That's a good choice
