Hi folks, I'm getting ready to build a new motor for my daughters GT. Hope you don't mind me bugging some of your for some info, I've never messed around with these Opel motors before. I've got a block that's been bored out to fit chevy 265 pistons and a whole bunch of parts that I'm not to sure where they all go LOL.

First question, the rods I've got don't have any rod bolts so I need to chase down a set before I send them off to have them resized. Any suggestions on where to get a good set of them at? ARP?

if its bored out to fit 265 pistons then it is a 2.0 liter engine. 265 pistons are cheaper than new stock opel pistons. but overall the engine should go together the same. Jared roden (greensmurf) made a 2.0 and he had problems with the deck height, send him a PM for questions (he also had probems finding rod bolts)

engine

Looks like I'm in the rebuilding the engine boat too. I was driving to hutch last night and my gt started loosing oil pressure so I pulled over. Now it knocks like mad so its currently still sitting out there ... sigh

I agree with pvcar. Get a stock engine to start with.

What you're doing is inheriting someone else's problem. You won't know if they started it off right or not.

There are guys on this forum that can take an engine like that and make it work, even if it started out wrong. But they've got a lot of experience behind them, have been around Opels a while, and most likely started with a stock engine themselves.

Having teenage daughters myself, the last thing I want is to put them in a mechanically undependable car. While Opels in general are really quite dependable, this engine you have now most likely will end up continually breaking down. Plus, all the manuals are geared towards stock.


My advise - think stock. Think dependable.

My daughters' car? A Saturn, sedan. Designed by Opel. With Opel suspension & brakes.

I did my engine rebuild earlier this year with 265 pistons. I can try & answer any questions you have. Do you already have the 265 pistons on the connecting rods? If not the rods will need to be opened up to .927" instead of the .906" stock Opel size. There is alot of info on rebuilding engines on this site using the 'SEARCH' feature.

As for the rod bolts, that will most likely have to come from OGTS. Bob L. has posted before saying ARP doesn't list them for a 1.9 & he used to have them special ordered & made when he ran his shop.

If you are doing a basic rebuild & freshening up the head with hardened seats & new,slightly larger valves, then it's really no different from doing a stock 1.9 rebuild. A machine shop would need to do some of the same work anyway on the block & head.

there is a thread on here, "economical CIH engine rebuild". this would probably cover everything you'd need, started at 3 junk motors and ended with my 2.0 running, couldnt have done it without this site.

This is my daughters "Hot Rod" so to speak, she got a Saturn this fall to drive back and forth at College so she's pretty well covered on that. I'm just planning on a mostly stock rebuild, but I might get in there and do a little head porting while I'm at it. She wants to put Nitrous on it, but I'm not sure that's a good idea LOL. MAYBE a little 25hp shot or something - we'll see on that further down the road.

We talked about doing a V6 swap in it, but just too much cutting and work to do to get there. I'm just wanting to build her a nice quiet, reliable little motor that runs on all 4!

Mach1Tom - thanks! I'll probably have a bunch of questions. I know small and big block chevy's real well, but these 4 cyl motors have me scratching my head LOL. No the pistons aren't pressed on yet. I'm just getting all the parts ready to take to the machine shop. The crank needs turned as it's got some surface rust on it. Thanks for the info on the wrist pin bore size, we'll need to do that. I'll give OGTS a call on the rod bolts, I've got to get some other stuff from them as well.

Greensumrt20 - I'll read that thread, thanks for the reference,

Put a Saab V4 in there.:haha:
Saab V-4=Ford V-4, used in Capris, Consuls, Transits, Corsairs(shrunken 4 door T-bird lookalike!),it even had a balancer shaft.
Saab's next engine was Triumph L-4 with it's jackshaft driven waterpump mounted high in the block and oddly angled cylinder head bolts. Saab finally developed that lump into it's own 8 and 16 valve engines. Then along came GM........and the rest is history :ugh:
