I am looking at doing some work to my car over the winter and getting it mapped in the spring. Looking to go for about 360 380bhp

Have been looking at replacing the turbo on my WR1 but there is so many to pick from and its all kind of a mine field as I dont really know what am looking for in terms of spec

What spec would you guys recommend for the power I am after and where the best place is to get the turbo from

Whats the diffrence between an 16,18 and 20g turbo? Is it spool up time, higher the number the better the spool up?

All advice and recommedations is much appreciated guys

Why? These are just numbers.

A TD05 16G will typically produce 340-350 bhp if you are lucky and is a reasonably quick spooling turbo. An 18G moves more air, spools almost as quickly and typically produces 360 bhp. A 20G moves even more air but will not spool as well usually and typically produces 380 bhp.

You clearly don't know anything about tuning these cars or turbos, no disrespect intended and therefore it is important that you find someone who is knowledgable who will hold your hand and answer all your questions but it should not be someone who is a supplier with a vested interest. Unfortunately there are not too many people with a depth of knowledge and integrity not to rip you off.

You are right that I dont know much about tuning thats why am asking the question and finding out what other people think/know and not diving in and buying somthing I dont know anything about. Just trying to build up some knowledge, every day is a school day. I am just doing some reserch at the moment to find out my best options.

Do you know of a tuner that I could contact and maybe ask them my questions?

My brother drove from Cardiff S.Wales last weekend up to Darlington County Durham(north of Yorkshire) just to get one of Harvey's modified 18G TD05 turbo's supplied, fitted and mapped to his car by Harvey and Bob Rawle,,, that should say it all really.

Advice from 'real' enthusiasts is usually free. Anyways can't you get more power from a WR1 without having to change the turbo - seems excessive?

What would you recommend for me then just looking for more power and torque from my car.

Not being funny mate but you've already had plenty of feed back on this topic already....., https://www.scoobynet.com/general-te...ore-power.html

Your turbo limits you to about 350 max. Get a full decattted exhaust and get a remap. all for about a grand

Mmm well as I say not all that clued up when it comes to tuning.

I have been told that the std turbo on the WR1 would not see me passed 350bhp thats why I had looked into replacing the turbo but dont know anything about them so was now looking for some advise and some help

Wont to keep the power moderate as I dont wont the expense of changing internals and have also been told that the std internals are good for 450bhp is this true? seems quite high to me

Has the car been on a rolling road before? It would be worth doing to get a check over to make sure everything else is fine and to get a base line to refer back to as mods are done.

Or Pm Harvey and see what he suggests

Thanks Andrew.
Your existing turbo and injectors can get you to the 340-350 bracket providing you have a full decat and efficient exhaust system including headers.
Header choice will depend on how far you want to go. If you are staying with O/E turbo then ported O/E and performance matched uppipe. If going a long way past the VF35 then probably tubular headers but with a special performance uppipe. With DEI wrapping of the tubular headers this makes this option relatively expensive.
Depending on what you are doing you do not need an FPR but should have a new Walbro GS 342 pump.
With a change of turbo and injectors you can run up to 400 bhp fairly reliably (or a little less) but beyond 400 bhp you are on borrowed time.
To run over the 380-400 bracket it becomes expensive.
Mapping the above, assuming you need an Ecutek licence would be £440 + VAT if we did it here in Darlington.
