nah dont have the money for major power, so likely to blow the engine up lol

I have had a look at the links thanks

Im just trying to make a list of that i need:
t3 turbo
Turbo manifold
Cosworth or similar intercooler
Fpr
ebay turbo chip from america
Piping
Oil cooler
more pipes
I think thats all?

What happens for the exhaust do people use custom bits? or flexipipe?

you will not be able to do this on the cheap. End of story.

forget the list, what are you spending and are you DIYing the build ???

Final note, Don't buy the Ebay turbo kit, 90% of will go in the skip, turbo included !

yeah im doing a DIY build, not planning on buying cheap stuff, so dont really have a budget, i would say around £1000 for parts maybe more? Im not planning on running major psi so not budgeting for megasquirt or alike.

To be honest my engine is not the smoothest, so planning to turbo it, if it blows so be it. gonna put an m30 in anyways then spend money on turboing the m30 properly.

Just wanted to make a list so i know what i need.

Some of this concerns even myself slightly!

£1000 isn't going to get it done!
Ok, you don't need a Lottery win, but I think you'll struggle to get it done properly for much less than £2000, unless you use loads of old scrap like I did!

not budgeting for megasquirt or alike.

You should be!

To be honest my engine is not the smoothest, so planning to turbo it,

If it's not running smoothly the last thing it needs is a turbo!

An engine needs to be in reasonable condition before considering uppping the power by 30% +.

if it blows so be it. gonna put an m30 in anyways then spend money on turboing the m30 properly.

It's a LOT of work to turbocharge these, to plan on having it blow up and then do it again is crazy!

Do it properly once and save a heap of cash and hassle!

Just wanted to make a list so i know what i need.

1. A decent engine to build a turbo on to
2. The book 'Maximum Boost' by Corkey Bell
3. A very long read through some old threads in this section of turbo conversions that 'Zoners have done

I done my conversion for about £1100, so it can be done but it isn't easy. This is my car: http://www.e30zone.net/modules.php?name ... 34&start=0

Manifold - less than £200
T3 Turbo £150
2.5" to 2" 90 degree reducer - £15
IC piping kit - £85
Volvo Intercooler - £25
Downpipe to existing exhaust - £200
Megasquirt (self built)- £170ish after import taxes etc
30lb injectors - £35
BOV £25
Oil line £35
Vac lines £15
Spark plugs - £15
LC-1 Wideband - £150
+ loads of donated parts from friends and a car I scrapped

"Total": £1120

I should think that turboing an M20/M30 should be easier since more people have done it and more parts are availible for them. But I would make sure my engine was running well before starting the conversion. Either fix your engine or put a new one in first.

Also if your doing things on the cheap atleast go for megasquirt to control the engine, as the parts to do it the other ways cost almost as much but without the control.

i should have added more detail, when i said my engine was not the smoothest, i mean that the tappets are noisy, and the cam is slightly worn. the engine itself still pulls like a train with alot of power.

My mate has a garage and part of the garage he rents to someone who does exhaust fabrications, so can get that done cheap i have already spoke to him.

I have previously messed around with skylines and other turbo jap cars so have lots of pipes left over from messing around with them. and even a t3

Still not sure why i must use megasquirt instead of a chip and fuel pressure regulator for a small boost increase?

Also i really want a turbo m30 or even a nono turbo m30 so just want abit of fun before i go for one.

Because you're altering the characturists of the running and if you want it to be at all succesful then you should have some sort of aftermarket ECU so you can map the engine correctly.

I can tell you, a simple eBay chip wont do anything close to the same job as a proper management system.

TBH, do it properly, or don't bother because otherwise you'll have a dodgey turbo system that will be plagued with problems by doing it on the cheap, if you aren't looking for much power give it a good service and look at getting some decent cams and programed ECU chip to get some extra oomph from it.

We aren't trying to fight you, or talk down it's just there are alot of knowledgeable people here and if you ask their advice it's best to heed it as it's the best around

i appreciate the knowledge, the guys on here are well respected (i heard about you on the skyline forum) That the reason why im asking these questions so i can get it right.

Looks like i may just hold out until i can afford an m30 donor car then, because that what i really want to do.

Dont´waste the money on a M20 just to do a turbo system if the plan is to get a M30 engine and turbo that.

not everything will carry over.

There are succesfull software chips out there but they are designed for specific turbo kits and specific boost levels. It´s not a case of one size fit´s all.
