1989 Xr3I Cab Turbo


Recommended Posts

This week I decided its about time I started a build thread on my 1989 XR3i Cabriolet.

 

It all started in November 2006 when I swapped my 1996 Escort RS2000 16v for a 1989 Escort RS Turbo. I already had a project in the form of a 1988 Fiesta XR2 which was almost complete. I'd wanted an RS Turbo since my early teens so this was an offer I couldn't refuse. The RST had a few months MOT left so the plan was to finish off the XR2, poodle around in the RST then start rebuilding it once the MOT ran out.

 

Well as with all of these things, the MOT ran out and then my circumstances changed. My wife and I were offered amazing job opportunities 200 miles away in London so we took them and moved. I finished and sold the XR2 to fund the move and put the RST in my parents garage with the intention of tidying it up whenever I was home.

 

Over the next few years I collected all of the parts I needed to rebuild and upgrade the RST but as I got further in to the build things changed again. Rust and time were against me. I got offered a 1989 MFi XR3i cabriolet by my brother in the summer of 2010 for really low money. It was solid throughout and more importantly an absolute bargain. The new plan: reshell the RST into the cabriolet.

 

Here's a few pics of how I got it:

A quick wheel change, much better:

So, I stripped the RST shell and sold it on. I fitted the '90 spec front bumper and Recaros from the RST. Then with the proceeds of selling the shell, I had the XR3i re-sprayed to make it minty mint:

At the end of 2011 she was parked up. Now the RST engine rebuild and transplant coupled with the EFi conversion began. As I already had an MFI RST engine with a few thousand miles since the bottom end was rebuilt I did things slightly diferent. Instead of an EFi bottom end with a CPS hole I opted for a bottom pulley and CPS mount from a CVH Sierra (36:1 trigger wheel). This is a tight fit (impossible with the engine in place) but will work fine :

Well lads I had a very successful weekend. I managed to seal the fuel leak but the car still wouldn't start. Eventually I traced a bad earth to the EDIS module and she fired in to life!

 

There's still a slight hesitation, but I'm putting that down to the CPS not being long enough (has a 6mm or so gap from the trigger wheel).

 

All in all very happy. Just need to replace the CPS, tape the loom, refit the dash and tighten the running gear. Basically just need time!

Well, I replaced the CPS last week and she seems much happier now, starts on the button and idles OK. FYI I fitted one labelled for "Fiesta 1.4, 1.6; Granada 2.0;Scorpio 2.0;Sierra 1.6, 2.0" and cut off the screw terminal. Bad new is the gearbox is on its way out so it'll have to come out in favor of the XR3i one until I can get it sorted/upgraded.


Just need to put a few things back together and then it's off for a setup. I have a week off again next month so it'll get done then.

Cheers lads! Well, as is always the case, the car is never without drama...

 

A month ago I spent a few days on the car. I replaced the gearbox with my old XR3i one and that sorted the whining and crunching for now. During that process I had to fit 2 new track rod ends as they wouldn't come out of the hubs for toffee.

 

But, after a few moves in and out of the garage and up and down the lane the sump gasket gave up :sad: Soooo, last week I replaced the sump gasket which cured that issue. FYI I superglued the gasket to the block before putting the sump in, that made the job quite easy. The rubber rocker cover gasket was leaking ever so slightly too so I replaced that with a cork one.

 

Finally the car is 99% ready for an MOT. I'm having a nightmare setting base idle at the moment though so I'm looking for a new OFAC MAP sensor. Once I've replaced that she'll be ready!

 

Cheers,

Hi Mate ,

What a cracking job you done. Is it mercury grey,the wiring looked a nightmare.

Cheers

Cheers Mate,

 

The wiring wasn't too bad, I'm handy with a multimeter, soldering iron and heatshrink which helped. I just wanted to make additions to the '3i EFi loom and I repaired any issues. I've since taped it all up and you wouldn't know it wasn't OEM.

 

Found some more issues the other week, I had to replace the Camshaft oil seal as it was accumulating oil on the lip and I've found a small water leak from one of the pipes on the water pump. The jubilee clip won't tighten any more so I need to replace it with a smaller one.

 

Lee :cool:

An update on recent developments! I think I found the issue setting base idle. Basically the head was warped and had one bent exhaust valve. I tried everything and couldn't sort it. I noticed that it had developed an oil leak from between the head and block so sent it away to be tested. I'm surprised it ran as well as it did!

 

I've now got it back after having a skim, new valve and 4 new exhaust valve seats cut. Just need to fit it and test it.

Nice project mate, that's my mates Orion, when were the pics taken mate. The Orion is turbo EFi now :-)

Just spotted your comment. The pics were taken at the end of April 2011 just before my brother sold it to Laren. I read on PF that it was EFi turbo now. Me and my bro had some laughs with that Orion!

It's much better with the turbo motor in it, was slow as a snail before :-) :-) just a shame he put Escort Cossie rims on it as they make it drive terrible :-( he defo should have left the Saff wheels on it.

I had another day down the garage on the weekend. Managed to get quite a lot done in fairness.

 

I re-fitted the head and it started first time... With no leaks :banana_dance: but the bonnet won't close now and it has a puncture :sad:

 

I think I've sussed the poor idle too, I blanked off the vacuum hoses that come from the inlet manifold directly below the throttle body (The ones that usually go to the oil breather). Apparently these are needed for the idle??!!

 

Jobs to do:

 

Fit Turbo Cooler

Sort Bonnet Latch

Sort Puncture

Re-fit oil breather

MOT

Clean and hoover

Drive

 

Here are a few more recent pics:
