Trying to come up with ideas to improve on the current set up in my escort cosworth.

Currently it is Stage 3 with rs500 cooler and ggr oil breather and alloy rad.

Got a new bottom end with 200 block, wrc oil and water pumps and 0.5 larger mahle pistons but not sure what to do top end wise

Don't want to go mega spending but what ideas can i go for???

you need to decide what power you are aiming for,that we people can advise on head work,cams,turbo,injectors etc

its down to the transmission on the 4x4's,so if all standard i would say 360-380 max.

If you say you dont want to go mega money, why not stay pretty much as you are... grey injectors, live map, fuel pump, Alcon clutch.......should be around 370ish, which makes a nice road car IMO.....

Cuople of the NMS lads have replied which links up to the NMS spec i'm going for it. Although built by my engineer up in sunny scotland.

Stage 3+

This conversion is becoming even more common as many owners choose to take their power outputs further. We now fit a new 0.55 T34 (or 0.48 T34 if maximum punch is required) supplied through Turbo Technics, and at this level we advise the fitment of an RS500 style intercooler and we supply our own custom design made for us by Radtech. Still utilising Bosch 803 injectors and a 3bar map sensor, Denso IK27 spark plugs are fitted along with a Group A coil and coupled with a full setup and mapping session the boost is raised to 26psi and around 360bhp/340lbf ft can be expected.

In addition we advise that the head gasket is replaced at this power level, and we now advise that the block is wire rung, the head face skimmed if required and reassemebled with a YBO611 headgasket. Wire ringing involves machining of the block face to insert a 1mm wire that protrudes slightly above the block face to both increase cylinder head fire ring clamping and prevent the head gasket from blowing outwards!

Along with this conversion it is often necessary to rewire the fuel pump and if necessary replace with a Group A Bosch 044 item. (033 in case of escort Cosworth) All other components such as exhaust and breather should now be uprated as a matter of course and again if required the radiator changed to an uprated alloy type. We supply our own range of radiators custom made for us by radtech in a range of core thickness from 50mm to 75mm!!

Just bought the turbo off pete that fits exact spec (t34 .55) and already have a wire rung block, radtec rs500 cooler and alloy rad.

If i was you, i`d drive to Stu@ motorsport developments to get it all set up was going to say Karl, but see your in Scotland Stu will do the bizz for ya

Holty

it all went too easy the new block i pick up on wednesday is freshly rebuilt and wire rung and the turbo was brand new on here from pete at rs specalists and i have rest of the bits.

What is wire rung?

bud-weis

that part of Karl's website has been updated since i last looked

i'd say go straight for the greys and stage 4,but your transmission will be on borrowed time if standard.

wire ringing is as above...

"Wire ringing involves machining of the block face to insert a 1mm wire that protrudes slightly above the block face to both increase cylinder head fire ring clamping and prevent the head gasket from blowing outwards! "
