Hi guys,

I'm building a turbo engine but I don't know what I exactly have to buy and what I need.
I'm a student so I don't have super much money.
I want I nice driveble mini turbo.

The following thinks that I already got:
NEW
- Fully new rebuild garret t3 turbo from turbo technis with exhaust manifold and downpipe
- Fullt standard rebuild gearbox with 3.1 diff.
- Ultralite flywheel Pre-verto with verto starter ring.
- Normal clutch plate and diaphram
- 1.5 roller rockers
- sw5 cam with followers and oilpump and duplec timing gear
- road valve spring 180Lb
OLD
- Standard 1275 engine block with pistons and crank (cam6581)
- Standard Turbo head.

What do I need to do.

I'm cnc machinist so I can make some parts selfs

Thank you
Regards maikel

I already got an exhaust manifold

I want to know whitch parts I need and where to but them.

Greetz maikel

you need a double grey clutch diaphram

an intercooler if poss

and all those other intresting bits

id change the pistons every thing else on the list looks ok,
you want to be thinking fuel system as the mechanical pump wont work and bulkhead box

Yes i moved to the darkside

if your a machinist then i recon you wont go wrong oil feeding the thrust bearings to counter a heavy clutch.

also the fuel pump you will need is any fuel injection pump, idealy an external type pump from an mpi car, spi will do the job but wont flow enought if you go bonkers with boost

make sure you're brakes are in a good condition.

maybe a lambda would be a good idea.

there is nothing wrong with a A-series that a turbo can't fix.

narrowband lambda guages are around £20 and very helpfull

one other item i thought of and don't see in the list: a inlet manifold a turbo carb and plenium.

Hi guys,

My lst is not complete.
I also got the following things.
A hiff 44 turbo with manifold and plenium.
SPI Tank and I got also an other fuel pump from Facet. Witch I have to look.
I've got also vented minisport brakes.

So you say that I need new pistons (omega 10cc dish) Wherefrom? MED, Avonbar, Morspeed
Intercooler, Can I get from scrapyard but from witch car?
So drill holes to trustbearings for a heavy clutch.

Can someone make me a list what I have to change?

- Rebore to 1293 cc
- centre mainstrap
- New bearings?
- Surface grinding bloack and head
- Intercooler
- New pistons

Maybe a new head?

you can use any intercooler that fits under your bonnet. the bigger the better in general

Hi,

Which pistons should I take.
I'm looking about 12 to 15 psi of boost.

Regards maikel

Maybe accralite pistons but how much bowl should i take

Edited by dimphy+maikel on 3rd Jan, 2010.

I'd use the standard ones as long as the rings / bore are ok.

In the 13's at last!.. Just

The compression ratio is the important part when sizing the piston dish. For 12 to 15psi I'd aim for 8.4:1 ish. A 2wd cosworth intercooler seems to be one of the favourites on here, and works/fits in well.

A standard head with good quality valves and guides, will be fine. You may want to enlarge the size of the chambers get lower the compression ration (all dependant on piston choice and bore size).

Personally I wouldn't go for a double grey clutch, especially for road use! You're better off using a single grey or go for a RTS clutch (if you search for RTS all should become clear).

Personally I would replace all bearings, and get the blcok and head refaced while you're at it. You may aswell make sure evrything is spot on whilst its apart.

1/4mile in 13.2sec @ 111 terminal on 15psi

Hi,

I've been looking at some pistons from morespeed.
0mega cast piston for 270,- or TURBO 21253 13cc piston set for 185 or TURBO Mega 10cc piston set 15psi for 230,-

Witch could i take the best

Regards maikel

I would suggest avoiding Morspeed.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

www.twin-turbo.co.uk

okay,

Where should I get my parts?

I've no great budget for all the parts.
What pistons should I take?

Regards maikel

My personal choice would be the 10cc omega's from MED

If something is worth doing, it's worth doing half of.

As John says the omega's get my vote too

The Cast Omega Pistons from med for 280?

Regards maikel

Yes.

If something is worth doing, it's worth doing half of.

Why not use the Metro turbo pistons you already have? They will be fine at your proposed boost as long as you have a sensible CR and efficient intercooler.

Spend the cash saved on a modern turbo instead.
