Is this an okay turbo build?
Turbo Mini Forums

1310cc
Omega pistons, not too sure on the cc, can you get them at 18cc? Or would there be a more suitable option?
Dry decked
Crankshaft i am unsure any ideas?
Lightened flywheel
Four bolt centre main strap
Under crown oil jets
Group A head gasket
ARP head studs and nuts
avonbar phase 2 cam, I havent heard anything about phase 3 really are they no good?
Mini spares belt drive kit
Two core radiator
Gt25 turbo, would you suggest anything else?
K&N air filter
Su HIF44 carb
Metro turbo inlet manifold
Metro turbo Fuel pump and pressure regulator
Mega squirt ecu

Is there anything else you would add to it?


I am unsure about the cylinder head and exhaust system

Gearbox i have only thought about sc box with double grey clutch diaphragm

If you can think of anything else to add that would be great

Forget the group a head gasket. They are rare as rocking horse shit and not required.

10cc omega pistons are a good choice just get the chambers in the head fettled to attain the appropriate CR.

Standard cam6232 crank will be fine

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

Is this not a group a head gasket?

This item is presently out of stock. See below for any alternative items.

Oh right my bad

Sounds like a potentially expensive build. What power are you looking for?

I would hope to achieve around 200 bhp, but it would be done over a long period of time

What sort of power are you looking for???? some things on your list are not really neeeeeeeded imo ( emphasis on the neeeded- more like want..bling bling ), other things are 160-200BHP territory ( again imo)



1310cc

Dry decked - is it needed?
Lightened flywheel - might aswell
Four bolt centre main strap - 2 bolt is more than enough but again even needed?
Under crown oil jets - if you want them but not needed imo
Group A head gasket - i wouldnt bother
ARP head studs and nuts - why not
avonbar phase 2 cam, I havent heard anything about phase 3 really are they no good? - PH3 pants on the road 'apparently' PH2 extremely good
Mini spares belt drive kit - there are some very nice chain drive kits could save you some unnecessary spending
Two core radiator - minispares super cool 2 core very good rad
Gt25 turbo, would you suggest anything else? yes that is a mahooosive turbo unless you want nothing untill 4krpm then try something smaller GT15/GT17/GT20/TD04(t2/t3)
K&N air filter - as good as any
Su HIF44 carb - turbo carb ( the na carb can be used but you need to be aware of the stuff it aint got)
Metro turbo inlet manifold - eye
Metro turbo Fuel pump and pressure regulator - yup
Megasquirt ecu - megasquirt is not really needed megajolt is more than up to the job, i admit im running megasquirt because of its extra features

Is there anything else you would add to it?
exhaust system -2" maniflow is a good system

Gearbox i have only thought about sc box with double grey clutch diaphragm -

If you can think of anything else to add that would be great

- disclaimer all my opinion ( and it took me awhile to type)

i personally wouldn't go 4 bolt centre main or the belt drive but thats my opinion others will probably say do it. I always thougt that crank flex was due to revs more than power and turbo engines dont normally need to rev that high. belt drives are ok but chains dont snap anything like belts but they do wear and change cam timing slightly. Your choice of turbo is a pretty big one i would shoose a smaller one myself as it will make the car more drivable but it depends what you want out of it or what use its going to get

My small bore turbo project http://www.turbominis.co.uk/forums/index.php?p=vt&tid=473901

About the timing belt, was out of stock when I wanted one, when I rang mini spares to find out when they would be in stock I was told, did not know and thought it unlikely they would never get any more in, because they where too expensive..

Edit.. I am meaning the timing belt kit..

As above. Forget the Group A gasket, they are NLA & I doubt they'll ever be made again. I managed to buy the last one MOSS had & managed to import two from Portugal after a massive search & help from a Portugese friend.

Would you suggest anything as a replacement?

bk450

There's a lot of stuf you do not need, such as the 4bolt main, group a headgasket belt drive etc,

The gt25 is overkill imo, a gt17 will do 200bhp, a gt20 is as big as I would go, produce more than enough power and still useable.

I would throw in some Arp rod bolts, they may or may not be necessary but I would for the sake of £70

Have a look st my build thread as its fairly similar to what your after.

gt1548 is basically a modern day version of a t2 turbo

gt1752 is what alot of people on here use and it was fitted to SAAB's as standard so could be quite easy to find one.

Forget about the belt drive and get something like the swiftune vernier duplex kit.

You should probably fit a cylinder head too...

Gearbox may help you along

A decent ported cylinder head is a must if your want big power. Turbo Phil is the man to talk to.

you don't need x timing chain and a belt drive, get rod of the belt drive.

Standard rockers or 1.3 rollers.

If your going the whole hog, which by the looks of it you are, I would look into an rts clutch

Turbo Phil does a good ofset head, but he's a busy man so get your order in early, I went to med for mine.
