Scottish drift Capri

Hi there,

First of all I have to say that I love your cars, and especially the philosophy behind them! Now I want a peice of that action!

I'm Ade from Glasgow and I'm a huge Ford fan... I also contribute to both Fast Ford and Classic Ford magazines.

My Capri:
Intended to be rebuilt to competititive drift spec very soon and it will be running a Ford V6 but which one is undecided as yet.
I have a 24v BOAwhich I intended to run as standard for a year then turbo it.
Now I am becoming tempted by a 2.9 12v after seeing your cars!

So would I be better with a 12v instead of a 24v?
I recently have been offered a 2.9 12v Turbo Technics twin turbo setup. Rated at 225 with two extra injectors on the plenum and a seperate ECU controlling them. The original ECU is still used but with a modified map.
My idea was to use a larger single turbo and larger injectors in the plenum to compensate. Any ideas on this? Could be a cheap way to avoid buying stand alone management!

Also how would a single turbo but plumbed in? Would the opposite manifold have to be routed through the turbo also?

Some pix of my car..... running a 150BHP 2.0 PInto

Awsome Capri... Perfect stance.

Thanks, it'll look even better when it's finished!

Ohh crap looking GREAT !

Awesome Capri, really like the rims and that it is black.

great work!

Another Capri fellow welcome here.
Thats some nice looking rims you got on the middle pics!!!

Regarding the engine i think a Cosworth V6 and a big turbo would be really nice, but the 12valve works just fine to. Standalone injection such as Megasquirt and so on works fine so avoid all sorts of extra injectors and so on. I have a map for Megasquirt thats works perfekt i you follow this recipe


Big turbo such as

(Garrett GT32, GT37 or GT40)

(Holset HX35 or Hx40)

(KKK27)

Seperate Wastegate
Megasquirt 1 v3.0 with TFI ignition
350cc injectors
Large Intercooler
Special exhaust manifold
Standard efi harness with modified contact to fit Megasquirt


This threads handles the modification on the fuelsystem

You must take both exhaust sides in to the turbo like this

Or something like this

I don´t recomend to fit some tiny worthless turbo, this engine needs real stuff to produce power!! The kits Turbo Technics made is crap and should be tossed in the ocean

Without any modifications a 2.9 engine with stock internals will produce 350-360hp at 1bar of boost

Some great advice there Mikael, thanks!
That manifold looks like a work of art!

I love the simplicity of the 12v setup, but as I already have a 24v I am very tempted to use it.
Do you have any experience of this engine? Is it as strong as the 12v?

I wonder if a standard engine would take the punishment of the same set up you use on the 12v?

My new wheels are Image split rims. RS 4 spoke stye but in 9x15 & 8x15

Must find some other rims for my capri when i see these

The 24valve engine has better pistons and so on, so its a better engine but the problem there is the high compression. They can be machined for lower compression of course just remove some material on the top.
If you have Ethanol on your gasstation you could use that fuel instead.

1bar on thes engines will give you just above 400hp

How much higher compression ratio is it, do you know?

Could always use a spacer plate or custom thicker headgasket to drop it down if needs be.....?

400BHP on 1bar would be nice

2.9 12v have 9.0:1 and thats ok. The 24v have 10.0:1 i think. A bit high. It´s better to machine the pistons than use thicker headgaskets. The inlet manifold is really bad by the way so that needs to be rebuild on the 24v
Brake horsepower can be a bit tricky with 1bar but with 1.3-1.4bar i think it will give something like that

Interesting....

Would maching the pistons not weaken them too much? Also make them run too hot considering they'd be coping with 400bhp?

Yeah know about the inlet, really could do with a custom one or at least it being cut and spaced out to increase capacity?

They can be machined straight if i remember correctly without tampering with reability

What gearbox and axle are you using in your Capri Mikael?

I'm planning on using a MTX75 hybrid (Scorpio TD/XR4x4), Cosworth YB clutch, custom prop and an Atlas axle with a welded diff' (3.77:1).

welcome and Mikael is using a getrag 260(?) from a BMW e34 535..

MT-75 gearbox don´t stand the power of turbocharged cologne I killed 5pieces

Interesting! I'd love to see more info on how that was fitted....

BMs are the typical drift cars for my mates, probably the easiest to get parts for around here!

höhöh so true

That looks quite involved!

I know some YB Cosworth guys use a Jaguar box as a T5 replacement. (sure I could get one cheap as I know a Jag breaker!).
I wonder if that would work? Only thing is that the output shaft wouldn't be as long as a typical Ford V6 box has....

Also do the 12v and 24v use the same type of Bosch injectors as the YB etc..?

If it can take the power it will work. It´s always much work to mount a gearbox from another car.

Cosworth use low impedance injectors and the cologne use high impedance injectors. You can put cosworth injectors in the cologne but Megasquirt for example don´t like low impedance

What injectors did you use?

Just been offered a turbo technics 2.9 12v twin turbo complete setup.... might use that as it is to start with them upgrade to a single large turbo afterwards.... or just go the whole way to start with, all down to money I guess!

440cc on my capri and 350cc on the sierra, as i wrote earlier in this thread, 350cc is perfekt on a stock 12v engine with turbokit.

But lose the thoughts on twinturbo, it´s not as good as single, more work to install the kit also. Twin turbo = double the cost and one big turbo is way cooler than a silly twinturbo setup

I meant what car did you source the injectors from?

Well the twin turbo kit I've been offered is complete... £500 for a rebuilt engine, ported heads, two T2 turbos, pipework, intercooler, and a freshly built MT75!

Thinking I could swap the turbos for a pair of T3's and up the capacity of the plenum's extra injectors to cope with this.
Rated at 230BHP with the small turbos, could probably do 300BHP with T3's and the gearbox may stay in one piece too!

Totally agree that a single GT40 is way cooler (and more expensice!).
Plus I want this project running as soon as possible so that could be left for later on. As the car is only a shell just now I can't spend all my money on just the engine

The 350cc is from a Saab, the 440cc is aftermarket

So just how strong is the 12v 2.9?
Have you had many engine failures?

Are there any typical weak spots in the engines?
