These sort of threads are what makes the MLR worth the membership.

Cheers Dave, I can't even take a fraction of the credit though, all I posted was the information that I've gleaned from other members (primarily grayw) so credit goes to them for actually working a lot of this stuff out.

The whole 400/400 debate (what's a "real" 400 bhp, are stock turbos capable of flowing a "real" 400 bhp, etc) will never be resolved, that's why I focused on stage 1 tuning rather than specific power levels.

Most people consider around 310 bhp measured at the wheels on a dyno dynamics rolling road to equate to 400 bhp at the flywheel. The stock VIII MR turbo is capable of flowing enough air to achieve this.

The whole torque side of things is another story, but again if the mapping is right, 400 Ftlbs is achievable on the VIII MR turbo as measured on a dyno dynamics rolling road.

I'm at around 380 but I'm wanting a genuine 400/400. So I was thinking about a 9 turbo,how safe am I without forging or is it a must at 400bhp.carl

The VIII MR turbo and IX turbo as far as I'm aware will flow the same, therfore produce the same power.

Regarding forging/forged rods for 400bhp+ all I'll say is CAN WORMS BIG

Ask some of the more experienced tuners/modifiers/mappers on here, but from what I've read it's debateable whether the IX turbo gives you much over the VIII MR turbo to justify the cost of fitting one - an FP white may be a better option if you want to replace the turbo for increased performance without losing spool.

I know grayw fitted an IX turbo to his VIII MR and wasn't overly impressed with the difference.

As for how safe a "genuine" 400/400 (whatever that might be!) is on a stock engine, that's also open to debate - I think a lot of tuners would advise upgrading at least the rods at around that level. Other owners are happy to run significantly more and "risk it".

Lots of members running 400/400 on standard internals, so no problem as long as it is mapped the right way.

You have a 8MR, so the turbo is good enough to produce 400/400. So you should concentrate on the supporting mods then. 3" Turboback, cams, etc.

There is a link to the differences between models at the top of the first post.

I have 3" turboback,boost controller,induction kit, fuel pump,remap so I was thinking cams and new turbo and I would be there.

With all those mods fitted and set up properly, plus the remap I would think you should be around 380 - 400 bhp anyway, with torque perhaps a bit lower depending on the mapping.

It'll cost you around £500 to upgrade the cams and then you'll need another remap to push you over the 400 bhp level and get the torque up. I don't think you need a turbo upgrade, but others might disagree.

All that considered, is it worth £500 - £1,000 to get that additional 10 - 20 bhp and a bit more torque?

Obviously it depends what you want from your car and your circumstances, but if it were me, I'd either leave it as is or spend a couple of grand, do the rods and turbo at the same time and aim for 450 bhp +. At least that way you'll notice the difference for your money.

Agree, leave at 380bhp ish or go all the way with Forged rods, Cams and Turbo.

The additional cost of buying and fitting Cams, Springs, Retainers, Head Gasket and a Remap IMO are not worth it for the 20-25bhp gain.

Actually that does make more sense, only thing is I think 450bhp is enough for the road,anymore would be a waste. Any ideas on turbo and cams.carl

Speak to your tuner and match the Cams to your Turbo choice

Excellent read!

Would it be worthwhile putting in a ballpark cost for purchase/fitting of each item and/or links to the relevent MLR traders for purchase/fitting and/or the "how to" for fitting each item?

Just an idea - either way keep up the good work!
