Hi,

I cracked my crankshaft on my Saab. Now I've had the engine pretty much rebuilt with Forged Pistons. So I was wondering what the next upgrade path to be. Sorry if this has been asked before.
I already 3.5in exhaust on the car. Do I get a intercooler or get bigger intake pipe.

Cheers,

guffers

Sounds exciting.........how on earth did you manage to crack the crankshaft - they are literally indestructable and the pistons, bearings and rods (usually in that order) give out first!

Was it just the crank, or was the engine completely FUBAR due to oil issues.


This gets me on to my next question..........


WHAT CAR DO YOU HAVE?????


That will be a huge help to gather advice on tuning. Generically however, I would suggest better tyres, uprated brakes, better suspension in that order before looking at a remap (assuming it is a turbo).

I don't know if the crankshaft was already damaged but I was doing 155MPH (GPS figure) on the Autobahn. As I came off the power it started vibrating and then died.
Rest of the engine was ok apart from the Conrod of piston 3 and the bearings. I already have pretty sweet tyres on my car already.

thats absolutely a new one!
bigger intake pipe won't do much, but changing the filter to a huge foam filter livened mine up on the noises.
bigger front mount intercooler will help most, if you're after more power then bigger turbo, injectors, remap.
Am in the process of doing the same after spinning a bearing

The tuning guide on the Maptun website is pretty good for performance upgrades by stage and the hardware required.

They are not the only place to purchase parts from, nor the only route.


Also bear in mind that the stages only give performance, much work is also needed on the suspension and transmission to be able to put it down.

Just got my gearbox back from LSD treatment.
£550 for a Cobalt diff imported
£300 odd in bearings and seals
£300 labour.

then £750 for clutch, and getting the flywheel lightened at least is free...

Sounds like a bearing picked up due to lack of oil.
