Mitsubishi GTO Photoshoot at Sitech Racing

Adrian Brannan from AB Carpix was in last week to get a few photos of the Underground Graphics Mitsubishi GTO. We were very pleased with the images especially since it was raining turing the shoot and was starting to get dark.







Full set of photos from the shoot are available in the Underground Graphics Portfolio

Sitech Racing at Knockhill Track Day and Weekly Update

Last week provided an interesting range of cars to work on ranging from a Mercedes CLK to a mk1 Fiesta.

The week also saw the Sitech Racing demo car #1 on a Knockhill track day. With the car set on low boost (20psi) it again performed perfectly while harassing a BMW M3 CSL for many laps.

Pauls S2 is so near completion, we're just waiting on the last part arriving.

The mk1 Fiesta has had a little bit of body welding and now is awaitng its RS1800 engine and box.

Ady's mk3 Escort has had all of its chassis mods carried out, so time to fit a new 2.0 ZVH with Gotech Engine Management.

Sitech Racing, Clios, inlet manifolds and brake upgrades

So this week at Sitech Racing agin has been quite varied.

Started with a oil cooler up grade on a Mitsubishi GTO which included a new set of oil lines as the old set had perished!

Had a Mondao in for a big brake conversion. It got a set of mk3 calipers along with a pair of Focus ST 170 discs (300mm) we also fitted Goodridge hoses and Neo brake fluid. We had to make a 4mm thick caliper spacer to fit.

Still continuing with the S2 rebuild, final stages now. Here is the Sitech inlet manifold that is fitted to the car. They sell at £450



We have a Clio 172 Cup in for its inlet manifold matching, timing belt and a set up.

Dyno day - Good result for GTO and Escort RS turbo

There was a dyno day organised by Clan Japan at the weekend at Hypertech.

Scott's Mitsibishi GTO powered by a Sitech Racing built engine achieved 376bhp on the rollers running larger turbos and a few tweaks.

The Sitech Racing demo car ran well also, with 380bhp but wheelspin beyond 380bhp prevented a higher reading been taken.

Paul's S2 RS Turbo project is coming along nicely and should be complete in a week.

We also have sold another one of our inlet manifolds.

Fast Ford at Crail Raceway and a new GT30 Turbo

So last week a new Garrett GT arrived for the Sitech Racing Escort. It came from AET Turbos down south. The turbo has been built to allow a higher boost pressure to be achieved and flow some Nos.


On Sunday Fast Ford were at the Crail Raceway Drag Strip. The Sitech Racing Escort RS performed well all day and posted a best time of 13.3 sec which was the fastest Ford FWD time of the day.

Also the Mitsibushi GTO of Scott which is maintained and set up by Sitech Racing, performed very well on it maiden run up the strip, posting a quarter mile time of 13.7sec.

Another busy week!

This week we have had a Fast Ford photo shoot for a customer with a restored S1 Escort RS Turbo. Just discovered it is the only Ford prepared S1 in gray! so I guess its RARE. It will be appearing in Fast Ford soon.

The black S2 Escort has been stripped and the knocking sound from the engine diagnosed as the pistons and rods having been installed the wrong way round!! Hello Piston Slap.
The Underground Graphics Mitsubishi GTO has had its rebuilt gearbox installed, I am quite looking forward to getting out and mapping the 2.2 Bar of boost that it will be running. We also finished the additional roll cage bars and got them TIGed into the GTO.

Collected a fully resprayed and smothed S2 Escort RS Turbo undergoing a nut and bolt rebuild, this will become the big job for the remainder of this week and next as we put it back together. This car has had a 2.0 ZVH bult using Cosworth rods and Mahle pistons, Newman cams, Sitech head and head gasket and GT28 turbo.
Also collected the Forged crank and full gasket set for the Honda Integra DC2, its going to be a very quick car when finished with its GT30 Turbo Conversion.

Turbos and more turbos

This week we mostly have been working on Turbos. It started off with a Sierra Cosworth with a missfire, that was diagnosed to faulty map sensor wiring and a worn fuel pump with an old fuel filter.

Next job was to set up and improve a Peugeot 106GTI track car with a turbo conversion. The extra fuelling was supplied by a MF2 5th injector kit. End result was a very nippy 106 GTI turbo.

We also have started another ST170 Turbo conversion using CP 86mm pistons and Eagle rods. We have reworked the head a little to improve the gas flow.

There is also an Ford Escort turbo on the ramp awaiting a bottom end rebuild, just waiting for parts.
