Has anyone looked at the feasibility of using an 89 through 94 Olds Quad Four 2.3 liter? These little motors are light and stock will provide around 190 hp, with some mods it can easily produce 210+ Hp.

Thanks,

I looked at this 5 years ago. What I remember is the starter is on the drivers side (front on FWD). It'll take some work to make it RWD as some things are backwards. Getting a tranny or bellhousing with a drivers side starter is tough. The engine itself is powerful considering it's size. There are aftermarket and factory performance parts available. It'd be great if you can get past the FWD related issues.

I'd be interested to see that conversion SVOPEL. Maybe the guy that did it will speak up if he's around here. One of the guys I work with is building one of these engines for his son and they seem to have a lot of mods available. He's been able to get several of these engine VERY cheap, Like in the 100.00 range. I'm not really hot to do a swap but this might be good one if the problems that GT-Freak pointed out can be overcome.

BTW, I'm new here so, what is Carlisle?

It is the Carlisle, PA "Import & Kit Car" show held in May every year, but, tons of imports show, and we try to make this the East Coast major Opel gathering. If you go to the photo section on this site and look for Carlisle 2003, you can get a good look at the field that was there earlier this year.

I think that Doug Grove was the name of the guy who had the Olds Quad 4 at Carlisle. I believe the issues he ran into was that the motor was very tall and was tough to stuff into an Opel engine bay. The Quad 4 also had problems steming from the dual cam and is less reliable than other engine swap choices.

I looked at the webpage Nathan referenced above and parts seem to be quite expensive...

Yes, it was Doug Grove's wife's white GT. A pic is Here He brought that one and a sweet red GT to Carlisle back in 1997. Entered them in the Custom Compact show and the white one with the Quad 4 took second (or third) place.

Confirmed - The white testarossa GT was first and the 2.3l red was second in the Radical Class.

I knew I kept these old printed copies of the OANA newsletter for a reason

Rear windows open also. No cracks or wiper scratches in the windshield.

Quad4 Fit in GT Engine Comparment

Picture of Quad4 in GT engine compartment looks nice.
Questions:
1. If GT radiator brace or heater core sheet metal required modification to clear carburetors and/ or exhaust?
2. Weight of Quad4 Vs GT engine?
