I'm sure there was a thread on this but i can't find it. I'm sure mergy mod will be along if there is. :Elaugh: Last week while the cambelt and clutch were being done evil Dan managed to twist my arm into the precat removal mod for the GTA
When I say twist I mean dangle it like a shiny thing infront of a magpie
Anyhooo I thought I'd share my experience of the mod with you.
Firstly can I say what a difference it makes to the speed of the car. Very noticable and it sounds awesome. The welding on the pipes is top notch and looks great.
I would definitely advise anyone who is having their clutch/cambelt done to do the mod and would do it again but and there is one but, you do need to be prepared to make lots of adjustments to get it to fit.
Take it to someone who is prepared to take there time and tweak it to get a perfect fit. The engine has to come out to fit the rear manafold. I modified the original GTA exhaust heat shields as I wanted to make sure the front and rear were still protected. I'm sure some people wouldn't be bothered but as these engines create so much heat it would be advised or you may have issues down the line.
You also have to loosen the power steering pipe on the pump and move it round so that the manafolds clear it. This can be done without bending the pipe if you are careful.
The pipes are very tight an sit quite close to the rear engine mount. You must heat the pipes with torch and bend them to get them to fit. I had to mod the bracket and protective plate on the rear mount to get mine to clear and not rattle.
You also have to remove a small plate on the subframe which is held on by a 13mm bolt. Also be aware you will need to get manafold gaskets and cat gaskets and maybe some bolts if your cat studs sheer off.
Once this has all been done you can enjoy the extra power,torque and noise.
Thanks Dan!! Very happy and a big thanks to Loz and Glen at autolusso bournemouth with whom I wouldn't have been able to do it with out
