Turbos, I'm stuck! What should I do?

[Kieran]

Okay, I'm stuck.

Turbos. What the feck should I do? I've convinced myself that I should 'build' Ariadne around the turbos, as they will ultimately peg the car back, and I don't want to have to spend time and money twice on things like downpipes, injectors and mapping, etc etc.

But it looks like a shedload of work, and I really can't decide if I should subject myself to such an undertaking.

Okay, let's get some thoughts and goals down on paper - that might give me a start.... I hasten to add that this is very simple thinking right now... Back to basics for a bit!

*The standard turbos are already whizzing their nuts off as standard, and if you wang up the boost, they turn into fan heaters!

* I want increased performance. However, I would sooner get more air FLOW into the engine - avoiding excessive adiabatic heating.

* This in turn would allow me to spend more time improving flow and such, than fighting heat and worrying about turbo durability.

* My turbos are getting towards near the end of their useful service life. There's some smoke these days, the cyclic noise of noisy bearings, and a lot of oil in the intake pipes - so I do need to replace them, ultimately.

* I want increased performance to a level that maintains day to day drivability, the twin turbo responsiveness, yet offers a lot of power.

So, if you would be kind enough to help me distill my thoughts into some sense, please!!

wtf are you asking us k

Errr.... Was just sounding out?! Brainstorming?

[richy rich]

if the turbos are fecked then change them dont d*ck about.

I'm also not sure what you're asking Kieren.

However, if you want a reliable VR4 with heaps enough power then stick to a standard set up. This may mean you need new parts of course but I don't know the exact state of the individual components.

There's sense in that K.
and unfortunately, the quickest and cheapest way to get more air in IS to up the boost.

Hmmm.... Not quite the reactions I was expecting - Perhaps I haven't made myself clear. The 'question' (if indeed it is a solitary 'question) is not "Do I switch the turbos?" (No dicking about here Richy! ) but "If i'm switching them, should I upgrade to something with a more flow capacity so that I don't have to run everything so hot?"

Or maybe not.... Oh bloody hell, I don't know!

I'm off to bed! I should already be in bed now anyway!!

Turbos run hot no matter what? if they are causing problems.. swap em out..if you want more performance from them, by easing airflow do so by chaning the coller pipers to a more free flowing design.. >

either that, or start driving the car to see if you've actually got turbo's !!

I'll reply to this in full when I get home tonight

Do you have an aftermarket intercooler?. If not put one on with some new piping to cool them better. Just replace them with some stock new ones. Has anyone tried porting the exhaust manifold and turbo to get abit more flow?. Also get some new air intake piping and air filters on there to. Does anyone know of any uprated actuators that you can get for these turbos?, I know that HKS makes uprated actuators so I don't know if those will work or maybe some evo ones or something to run a bit more boost.

Has anyone tried this Cry02 stuff?. check it out:

If the existing turbos need replacing then replace with originals, fit an uprated FMIC, maybe sort the fueling out, and boost controller. This should see you into the 320+ps area which is as high as I personally want to be without having to worry about internal upgrades.

I guess the above will cost a reasonable amount, but nothing like the cost of internal upgrades too.

Ultimately, what do you wish to use the extra power for ? This is a serious question Kieran. I know you enjoy the 1/4 mile run but is that worth spending thousands on ?

[bradc]

Kieran, if you do want to upgrade the turbos, you are going to need to spend about 3000-5000 pounds on the upgrade.

You will need new manifolds, downpipes, ecu, injectors, turbo piping, etc etc. It is a big job. Our stock turbos are obviously the restriction on our cars, but there isn't much that can be done unless you are willing to spend a lot of money.

If you stick with the stock turbos you can upgrade the car by quite a bit and get very good performance out of it, look at BDA, Derek or Nick Mann, they are on stock turbos and have very fast cars, a lot faster than stock.

so he can park it in the drive with the bonnet up with a sign saying this car has 320bhp (calculated)

Lol richy .................... STOP taking the p|ss!

Anyway Kieran ............ have you worked out exactly what you are trying to ask yet. M'thinks you were tired last night

WHY

Anyway Kieran ............ have you worked out exactly what you are trying to ask yet. M'thinks you were tired last night

Glad im not the only 1

Yes, I was very tired last night..... very tired!

In answer to your question.... No I guess not. I'll have a think about how to phrase it better and come back.. Must dash now - looooong day ahead again!!

All bollox. All of it. Just shut up already!

If you want bigger turbos, do it. If you dont, leave them.
If you want bigger turbos, it doesn't mean spending the earth. You DO NOT need a full aftermarket ECU or any of that poo until you really want to push past what the stock ECU can handle. we KNOW that the turbos limit the performance, just look at any dyno graph of a car with raised boost... It just wont hold boost pressure. I expect the standard ECU is happily mapped out past what our turbos put out.

You need 3 things (the fourth is optional...)
1) time
2) money
3) the inclination
4) a divorce... /pokes tounge out at Alex for reading MENS forums

Have fun

Kenneth, I dunno about the not needing to spend big money thing. You are looking at an emanage at absolute minimum, even if you do get second hand td04's or something, you are still looking at a lot of money.

Zentac, Valmes - how much approximately did your turbo upgrades cost?
