1.9 to 2.4 Conversion Project Started

[asdasc]

Thanks. By the way, these guys are in the section of Detroit you don't want to be caught in at night. If you have any issues and need someone to stop in and see what is going on, let me know. By freeway it is only about 30 minutes away, and I drive past there pretty often for work.

BTW price list so far:

Total Seal gapless 2nd rings.....$75
305 Chevy pistons................$160
Chevy ring kit........................$15
Pistons decked.......................$30
Rods cut for Chevy pin............$75

Flywheel modified...................$151

Chris, that will be a quick ride!
My next big Opel project will be a clutch upgrade like you are doing. Even with my slightly modified motor, the stock older clutch is barely enough to take hard driving. Will have to do some reading to see what needs to be modified.
Thanks for the pictures.
Lyle

I am replacing the head bolt holes with these.

Other than getting the rod ends opened up for the chevy pins, are you doing anything else to get them reconditioned?

I was debating if I needed to get mine shot peened or anything. I am not sure what all is involved in getting them 'reconditioned'. Also I saw you cleaned them up, did you also lighten them?

THanks,

Money!

I can't wait 'till we have our GTs on the same piece of pavement!

Reconditioning the rods mean making sure the big end is true. i also had them shot peened too. I ground off any excess metal from the rods exept from the weight area, but did round the corners. I didnt lighten them but I did match them to the same weight. 612 grams

Got the block back from the shop. Cylinders bored, deck sanded, cleaned, and Timeserts installed. Head should be done monday, getting bearings installed, and hade it cleaned to get the surface rust off.

[opelwasp]

I am also going to need a full set of main and rode bearings in .020 over size. I have a full set of .010 over I am willing to trade. Any takers?

[spdkilz02]

Chris its all sounding good...maybe this would be a good project for me in the winter...cant wait to see how everything comes out, good luck...

[opelwasp]

Got a call today, crank was sent on friday. Should be here on thursday.
I am dying to get this car back together.

[T-6 driver]

Awsome,

Like I said, I will have my check ride next week, after that,we can get our cars rollin!

[opelwasp]

Woo whoo
Crank came in today. Gonna get the needed bearings tomorrow, 20 over for the mains and std for the rods.
Next I need to put it together and check clearances. Grind a little here, a little there. Then ta da.
I hope to hav it running befor the end of the month.

[jordan]

Did you go with the offset grind method for getting the 2.4 displacement?

[opelwasp]

Yes, it only cost me $530 to get the crank welded up and reground.

Time for an update.

[T-6 driver]

Chris,

When? I am hoping to have mine running in a few, but when do you think yours will be done?

[opelwasp]

time for another update. buy the way, when using "Great Stuff" gasket sealer and a stroked crank you will need to either use a steel oil pan or grind the aluminum one to clear the rod bolts. OOPS!! Right now I am waiting for the oil pan to finish curing and I'll be ready to drop it in.

[baz]

do you grind the paint off for the starter to ground to the engine or run an extra ground wire with that supa doopa paint finnish ?

[opelwasp]

Ill do that when I put the starter on and I have other grounds.

[opelwasp]

Small update. Got the engine back in the car. The new flywheel and pressure plate clear the bell housing. Now to fit on the ancillary stuff, and decide on fuel delivery.

[opelwasp]

Now I need some expertise from those smarter than I. Will a stock Euro 2.0L EFI work with this engine I've built? Or should I try to trade the whole EFI for a set of DSD Irmshers (short runner) with 45 DCOE's? I want EFI but if too much money is needed to make it work with this engine right now I can get the DSD for awhile.

It will run, but don't expect to be able to 'wind it out'. I ran Euro 2.0 EFI on a stock Opel 2.4 with a small cam. It had great torque from 1500-4000 rpms. It would start to ping by 4500 rpms....after that it wasn't safe to rev it. I bumped the fuel pressure a bit, loosened up the air flow meter flap tension, and increased the idle air bypass, otherwise it ran dead-lean by 3500 rpms. It was tolerable around town, and the torque improved even more, but even with the relatively small hydraulic cam it had...the air flow meter would flop back and forth (due to the pulses from the cam overlap and the reduced air flow meter spring tension). Of course, when the meter is flapping, it's going 'rich, lean, rich, lean, rich, lean...'

I tossed the factory EFI and threw a Holley 500 on that engine, and never regretted it. It ran much better, and was actually tuneable, and revved to 7500 with ease. I will eventually go back to EFI on that engine, but NOT with the factory ECU and especially not with an air flow meter! Megasquirt all the way.

[opelwasp]

Thanks for your reply Bob. Well I guess Im screwed at this point. My manifold has a hole in it, yah I was porting it. Unfortunatly I am broke right now and cant get it welded up to finish it. So now I have to put it on hold. It sucks I have everything done but the intake and now I'm stuck.

[roadings]

how depressing i've been sitting here floating around in the gulf waiting to see what kind of ###'s you get from this engine. sorry to hear about the manifold.
