B16CVH Posted March 31, 2009 Share Posted March 31, 2009 Hi all, I pick up my first Westfield on Sunday so im alike a kid at Christmas! After looking at the car, i see that it has a solid rear axle from what looks like a Mk2 Escort, the guy didnt really know too much about it as he was an elderly gentleman and had only done 387 miles in it in 2 years! My intention is to fit all the current powertrain from my recently "wrote-off" Cosworth managed Escort RS Turbo into it but i was just wondering as to whether the axle, diff, g.box etc will be able to cope with the power increase? (Circa 240BHP) Also, my RS Turbo has Cosworth brakes all round and was wondering if these would be able to be fitted?? (current westie setup looks like Mk2 fronts with solid discs with drums at the rear) Any help would be much appreciated and there will probably be a lot more to come!

westy666 Posted April 1, 2009 Share Posted April 1, 2009 congrats on the purchase ... get those piccies up Axle will probably be alright altho you may find you get through driveshafts depending on how you put the power down. gearbox ... will need uprating if its a boggo type 9 - BGH/Quaiffe etc ... some peeps keep them standard over the 200 barrier but probably drive with a certain degree of mechanical sympathy in order to do so. Deffo worth giving the brakes a good overhaul at the very least along with some mintex type sports pads - but the the disc/drum setup will still be sufficient to stop a westy quick enough still. The next step up in the braking dept would be 4 pots up front ala willwood along with some master cylinder upgrades - depends on your budget, I reckon you could get away with a well maintained mk2 escort brake setup still. Cooling upgrades for the turbo setup need to be up top of the list i'd imagine. Damian Quote Link to comment Share on other sites More sharing options...
B16CVH Posted April 1, 2009 Author Share Posted April 1, 2009 Cheers for the info, the car i have brought is to the left but i will soon look different to that, i am removing the stickers and replacing the wheels with some compomotives and the RS engine in a months or so time. Do you think the radiator would be sufficient for the cooling? The current one in my escort is an aluminium affair, i am also going to be running a chargecooler in the westie so no need for front mount intercooler etc. I will prob go down the front brake upgrade route then and leave the rears, i might go for vented though as the ones fitted are solids!

PeP Posted April 1, 2009 Share Posted April 1, 2009 I think most on here will tell you to not use vented disks ,they are heavier than solid. Mine are just grooved,I suppose drilled will be ok as well. Quote Link to comment Share on other sites More sharing options...

Martin Keene Posted April 1, 2009 Share Posted April 1, 2009 Re the back axle, it's not the power that kills them, it is torque. I don't know a lot about the RS Turbo motor, but I suspect it doesn't produce massive torque, like the Cosworth, so providing you are not way above 160-170 lb.ft you should be ok with the back axle. Assuming the diff is in good nick, it is normally the drive shafts that go first. Some people recommend fitting uprated ones, but standard shafts are 1/6th of the cost and provide a nice insurance policy against breaking something more expensive. Although, all that said, the car only weighs half what the Escort did, which makes life a lot easier on it. Same goes for the brakes really, the standard twin pots solid discs are design to stop 1000kg + of Cortina, they have no problem stopping a Westfield driven hard, you might run into problems if you do a *lot* of circuit work with *big* stops. But you will never encounter a problem on the road. Aluminium 4 pots on the solid discs are a worthwhile upgarde, even if only to save weight.

westy666 Posted April 2, 2009 Share Posted April 2, 2009 On the rad front it's probably worth measuring up the difference between your escort rad and the one youve got in there right now - there isnt a whole lot of space up that end to take a particulalrly wide rad ... although you can go deeper to compensate. Polo rads are often used but I believe you;d need to be looking at atleast the golf equivalent to handle the 240. Quote Link to comment Share on other sites More sharing options...
FW500 Posted April 2, 2009 Share Posted April 2, 2009 Space is your enemy with the turbo setup. Looking at what Polly X on here and Passionford has done would be worth doing. He's certainly made the turbo setup work well in both his own car and Porkies. I've gone down a similar path (with the Vauxhall LET engine) and have a 450Bhp setup although cooling is limiting that to around 300Bhp at present. I'm also running a chargecooler and a V8 rad and whilst the engine cooling is perfect the intake temps get completely out of hand anywhere over 1Bar. I need a larger pre rad and also perhaps an additional rad at the rear. I went for the T5 box from a RWD Cossie and that's well within it's comfort zone - I'd suggest you do something similar. Good luck with the conversion! Quote Link to comment Share on other sites More sharing options...
Jenko Posted April 2, 2009 Share Posted April 2, 2009 I have an N/A 2ltr cvh running 200bhp and a fair amount of torque(192ft/lb).....So far so good, I've done a few track days with and nothing feels strained. My car is an SEiW, but gear box appears fine.....I'm using an AP clutch from a crossflow..... Quote Link to comment Share on other sites More sharing options...
B16CVH Posted April 2, 2009 Author Share Posted April 2, 2009 Thanks for all your input guys its very much appreciated, nice to talk to people who know their stuff! I think i will just drop it all togerther then take it steady and keep an eye on the guages etc. As i dont pick the car up until Sunday im not entirely sure as to the exact parts fitted, i supose once i can find out whats fitted, i can then decide if she will be able to cope with it. If it does have a std sierra 5 speed, would the prop be a custom jobbie and also, would i be able to drop the T5 straight in or would i have to fiddle around??

markcoopers Posted April 2, 2009 Share Posted April 2, 2009 You need to chat with Neil, (Crash bag Wollop on here), as he has this engine in the car with the mods you are thinking about. He may be down on the 240bhp, but he has a good chunk of the stuff. Gearbox will be fine if it is a type 9.......whick i will bet on it being. Revs and abuse kill these, but a sensible clutch might be an idea. Axle will take the abuse, LSD would be worth while though. Having said that 240 and all that turbo spooling tourque will be an stern test, lets discuss it again when you break it. Brakes, the set up you have will be more than enought. However circuit work will start to reveal the limits, especially if you fit stickie tyres. As others have said, a well troden path to 4 pots and new master cylindars to copy. Ali rad is a poss, but std westfield affair is a 4 core job and to be honest pretty good. Quote Link to comment Share on other sites More sharing options...
betarev3 Posted April 4, 2009 Share Posted April 4, 2009 Jenko, I note you are getting 200 bhp from a 2.0 CVH, whats the secret!!!! To date I am running a 1.9 american tall block taken out to 1980cc Bottom end lightened and balanced. Early cylinder head with cross hatching which has got the largest inlet valves that fit, standard exhaust. Gas flowed and checked on flow bench, excellent results. R1 carbs 40mm choke. Purpose made exhaust manifold longer primaries westfield one to restrictrive. 210 deg cam with solid lightened lifters. I am running an uprated distributor although this would make little difference on top end power. Have had is all set up on two rolling proads and can only get 178 bhp. I am told the limiting factor is the way the valve train works and head design ? The engine happy revs and puls to 8k max power at 6.5k. What am I doing wrong Quote Link to comment Share on other sites More sharing options...

Bob Green Posted April 4, 2009 Share Posted April 4, 2009 I would have thought with Cosworth power, you would need a T5 gearbox, unless your thing is to change Type 9's on a regular basis. I have a factory car and I "think" the chassis around the Diff area is different as well to cope with the extra torque, (not too sure about that) Quote Link to comment Share on other sites More sharing options...
