Project Freeze My engine Off (SAAB B207R Supercharged)

[vocky]

quite easy, the earlier B207 engines had a four balance weight crank and obviously a GEN 1 block, the later B207 have an eight balance weight crank and a GEN 2 block.

I have an early B207 block which came with a four weight crank, circa 2007

If you look hard enough you can see the engine number is a B207

 

[chill]

lucky devil

will have to keep holding my breath and stop pushing for power
looks like i will have to lighten and add down force

 

[vocky]

just buy Haggi's A20NFT block and swap everything over, job done

the actual contents of a lifter

the bat cave saw an engine build this weekend its a wedged 2.0l thats compound charged
had to replace the dowels they got machined off


but the new bench got some weight on as the engine came from a mate who had a few heads laying about

 

[evocarlos]

AEM engine position module on its way 24x crank and 1x cam in one box just need to adpot it to fit the inlet cam


i have a good friend in america who is going to help with mounting hardware

 

[evocarlos]

been playing in the batcave with a head Dave Gilbert gave me its was pretty muffed
very dirty



16 bent valves


stuck it in the wash bosh for 4days then jet washed it its came out much better


now to fix the 14 cracked valve guides

 

[evocarlos]

so the epm came and ive spent the last day or so building the contraption to make it work

saab power steering pump cut down alot!


back side was flat sanded as i don't have a milling machine


mounting the epm to a spacer plate


was not happy with the imperial bolts on the epm so stripped the unit to change them only to find one bolt on the pcb broken from the factory no screw head in sight and the main case screws were glued in


fixed it with an old pc case screw


changed the 8/32 studs to m5 threads then cut the bolts to length


made sure they would clear the pcb when bolted in


like so


taped the outer case for m4 bolts and then fitted new ones


cut the shaft and put the notch in for the drive on the epm then shaped the spacer to the same shape as the ps plate then made sure it was running as true as i could
added 2 m4 countersunk bolts to hold the two plate together


and thats the unit complete just need to add the wires to the ecu loom for the cam and crank signal and power and ground


this will give me the option to run full sequential and wasted spark once i change the firmware from semi sequential (crank only)

 

[evocarlos]

it fits

 

[evocarlos]

It appears gen1 is a load of shot to
So here's the next one


And d a TTV flywheel to suit


Here's a head after 5 days in the degrease and a jet wash


Came up real clean


I had to strip out the bits and lube them so they didn't go rusty

Does the sequential ignition make much of a difference ? How did you get on with the AEM abs unit does it work well with the vauxhall can connection and can you configure it to disable traction control abs ect ?

sequential fuel injection half load at compression stroke and the other half at intake stroke giving the same power with less fuel consumption
it was running without a cam sensor so need the epm to get the cam sensor for other things not just fully sequential

im still running the bosch abs pump the abs is stand alone and has no need for input to function t/c is part of the z22se ecu the abs ecu send signals to the ecu to show front wheel speed greater than then rear wheel speed then sends a torque reduce request causing the ecu to shut the throttle flap and or cut the fuel
the aem has its own t/c so you just need to give it a front and rear wheel speed input and it can be configured to how you want it ,gear,slip target,fuel cut,ignition cut,throttle % cut,timing retard,

in other news clutch has had it


and the head gasket


rince and repeat

 

[milo]

What caused the head gasket to go? And take it clutch wasn't upto the increased power

 

[evocarlos]

lack of cooling from a single fan and having the temp probe in the wrong location so it was not giving the right reading its like its melted the coating on the gasket and then i got water in the oil

yeah the clutch did well for what it was its been funky for a while some days hard some days normal so guess it been going slowly

ive now got a list of jobs as long as my arm and then a parts list the same lol

 

[corsaZ22se]

your not having much luck at the moment
at least it can be fix and your the man for the job

 

[KevinH]

Sorry to hear about the head gasket and clutch.
I'm sure you'll have it fixed and running again soon though.

 

[evocarlos]

New 500hp capable clutch is in the post and got a load of gaskets to pick up today new block should be ready for early next week will do a proper update with pics later on

 

[milo]

Who doing your block?

 

[corsaZ22se]

i thought you had some fancy clutch before?

 

[evocarlos]

i thought you had some fancy clutch before?

Had the twin plate when the f23 was in but then went back to a single plate with the m32

Who doing your block?

Not sure on the name but its not local to me

The old block now stripped the evans Coolant has washed the inside

All shells look normal


Crank looks good to


A bunch of new gaskets


And the new clutch
