Fao AshG also Chassis strength?

[Danb1987]

Just a quick one... How much power will the 2mm chassis take without the need for major strengthening!

To ash how hard was it in fitting the Saab engine and running gear? I have a friend who has big ambitions with these engines and there tunability..

Also did you use the said engine to pass the iva or just went in with a book spec car? I can't find your build thread lol

He went through iva with a 1.6l pinto. Then upgraded and I'm sure he said he wished he pit the Saab engine in first.

[Danb1987]

Iv been thinking that aswell to be honest I can get all the running gear etc pretty cheap so it's worth looking at as an option, depending on the iva situation

Just fit a cat and get it properly tuned and iva will be no problem whatsoever

[Danb1987]

Thats what I was thinking... I'm going to need lots of well needed advice off ash once my build starts

You don't need to use 2mm wall tube to take extra power you need to add extra braces....heavy cars hit things harder as Mr Chapman used to say.
Extra power will highlight the geometry problems with the Sierra based chassis.

mine is only a book specification 1.6mm chassis and hasn't fallen apart/bent, if i were building a chassis from scratch again to take plus 250bhp i would cross brace the front frame and gusset all the tube joins with 3mm plate to increase rigidity. it wasn't any harder to get the engine in than any other engine tbh. the tricky part was working out where to put all the extra bits like charge cooler water pipes oil cooler. propshaft took a while to sort as dunning and fairbank were out of the conversion kits to convert the omega box to a standard output flange. you also need to make a spacer for the clutch slave cylinder. there are at least ten people that i know of that have fitted a saab turbo engine in their car. but as far as i know there are only 4-5 people that have actually made it all work and usable/reliable on the road
