Finally having some time to assemble the 1.9 cvh turbo engine destined for a fake
Escort RST.



1.9 block back from machine shop. 82.5mm bore (0.5mm oversize)



Custom CP forged pistons - 8.2:1 CR



Pistons and connecting rods assembled




Decided to keep the factory breather cover in place.

Found my Hazet piston ring compressor tool



After some trial fitting I had to chamfer the bottom of the cylinder bores for connecting rod clearance. It was a bit tight with only 0.020" clearance.

Engine clearances were fine:

Main Bearings: 0.0022"
Rod Bearings: 0.002"
Piston to Cylinder: 0.005"
Piston to Deck: 0.004"



Notice ft. lbs. torque required for correct rod bolt stretch of 0.0055" written on connecting rod beams.




Oil pump install next!

 

Have been waiting for you to start a build thread!!!!

Keep up the good work mate

 

Nice fella.keep up the updates.

 

good work so far

 

nice mate , why the 1.9 ? are they more common over there ?

 

I wondered why you hadnt done a build thread yet either!!

Pics of the car needed though

 

The 1.6 cvh escort was around from 1981 to first half of 1985.
1985 and later had the 1.9 sized engine. The best one for a performance
build is the 1.9 HO engine. 108 and 110 hp versions.

The 1.9 is more common to find in the wreckers yards.

 

I 'believe' the block is the same as the 1.8 cvh Sierra we get over here, but with a different crank etc

 

Hello Marcyg,

The 1.8 cvh Sierra uses the same 88mm stroke crankshaft the 1.9 engine uses.
The north american 1.9 has an 82.0mm bore size. I believe the 1.8 Sierra has
the 80.0 mm bore size. I am not sure if the small bore Sierra block is taller than the regular 1.6 block.

The cranks are the same, and the blocks are different.

 

Get pics up of the car pleeeeaaassseeee

 

Looking good Perry, I like your posts on the cvh engines etc

(and as maxwell says lets see the car its going in)

 

1986 escort inside view.
Outside view does not look like much yet - needs proper wheels and tires

 

235 mm clutch for 1.9 cvh - Centerforce performance cluch for a 1990 3.0 liter Taurus SHO (Yamaha V6 220 HP engine)
A mixing and matching of flywheels (2.3 Turbo XR4Ti or 2.3T Thunderbird) bolts up to 1.9 cvh crankshaft - same OD as factory 1.9 flywheel, but allows for the 235mm clutch instead of the small 215mm clutch.

 

get updating on oddkiddcreations as well mate, i've got some questions for you!

 

What questions? Could aske me here?

 

Getting closer!!

 

Thats an odd looking sump!!

 

Standard 1.9 tall block sump.

Another angle:

 

sorry Perry, didn't see your reply until after youposted on OKC

 

Test fitting turbo manifold and turbo.



Have a few small issues with the alternator bracket
I will think of something.

 

whats the issues with the bracket perry?

 

I was on ebay us yesterday and was flicking through american spec escorts! I noticed the door card in the pic you posted and noticed a 1982 escort exp had the exact same door card! Is that the model of escort your doing this conversion to?

 

Hello Maxwell

I replaced the standard door panels with ones from a 1985 ( I think) Escort EXP.
I also took the seats from the Escort exp.
They look nicer than the standard Escort ones.

 

Ahh ok mate!!

Have you any pics of your inlet? And of the throttle bodie position!!?

I was looking at how tall and also the shape of your rocker cover, and i was thinking of where you will have the charge pipe. I think you should be uber cool and get a proper rs turbo cover and charge pipe and inlet!! Would be a nice touch in your engine bay!

 

Hello Max,

The inlet is a side trottle body.
I have upgraded the standard 50mm throttle body to a 56mm BBK version designed for a 3.8 V6 Mustang.
The factory inlet has been modified internally to balance flow and increase flow as much as possible.

 

Degreeing roller lifter camshaft:



I will start with maximum valve lift at 115 degrees BTDC.

 

Just seen this Perry! Good work!!

Rob,

 

Thank you Rob!!

Cheers

 

Cylinder head has arrived!

Port cross sectional area was kept on the small side to promote high velocity.
We ended up at 330ft/sec at 6500 rpm.

The finished ports are very quiet on the flow bench, and show no turbulence
all the way up to 48" of water.
The exhaust port was kept small to keep up velocity for turbo use.
If money was no object the exhaust port floor would be welded up and raised.
The inlet port is tricky to increase airflow. The swirl type port requires someone
with experience to get them to flow without losing all the port velocity by grinding it
larger everywhere.
We did experiment on 2 cracked heads to see where material removal was beneficial,
or detrimental in some areas.
Just grinding the port bigger made little flow gain.

 

Turbo fittings have arrived.
AN fittings for water and oil.

 

Haltech installation begins.

Under center of dash plate.

 

Looking good squire, so nice to see something different for a change... well different to me anyway!

Quick question, got a pic of your porker or even better a video, i need to hear those carbs

Ginge

 

Fitting new 3" V-Band down pipe with the ATP T3 5 bolt high flow V-band style internal wastegate.

I couldn't bring myself to use the restrictive factory down pipe. This should improve turbo spool up and reduce excessive back pressure.

Rule of thumb for turbo exhaust sizing is 1.5 X size of turbine exducer. 1.89" X 1.5 = 2.83" So 3" OD exhaust should be perfect.

 

 

its lookin smart mate, the rocker cover seems very very different as well, what sort of power are u going for ? will u be using the seimens range of injectors ? this engine will be EFI yea ?

 

I think theres a pic of his ecu above mate, so im assuming efi yes

Perry, awesome work, I think you have a little more room than us in the bay?

Liking the down pipe, very big flex joint though? And i take it the two bungs are for EGT and Lambda?

Im very tempted to have an EGT sensor in each manifold runner when i go fully sequential so i can match the fueling on each pot.

Best of luck and keep the pics coming!

Rob,

 

I am using RC fuel injectors - 550 cc/min (52 lbs/hr)
These injectors should be fine up to about 250 hp @ 80% duty cycle.

I will only be using one exhaust bung for the wideband O2 sensor.

 

Come on Perry, it must be update time by now?

Rob,

 

Hello Rob, update just for you


Escort RST head gasket - very high quality thick steel core.
Gasket bore size just slightly larger than 82.5mm



I put the new cylinder head on - torqued in 3 steps 20, 40 and 60 ft. Lbs.
I will re torque after a 24 hour period, and once again after engine is run in.
A pain in the ass I guess, but required with head studs.

Crower dual valve springs, valve retainers, and valve spring seats (To hold spring steady at bottom)

 

Engine ready for flywheel and clutch.



Added 36-1 crankshaft sensor to front pulley. Made a new pointer for TDC.
0, 10, 20 and 30 degree markings on pulley to verify engine management timing
mapping.
