Bolt size and rebuild

[spyderdrifter]

Ok I have two questions,

1: I need to know the bolt size and thread pitch for the manifold to turbo bolts on a 97 gst spyder with factory manifold and turbo.

2: where can I find a rebuild kit for my oem clutch master cylinder from the same car?

You cannot just use any old bolts for the turbo to manifold. They are probably some of the strongest bolts on the entire car. I would replace with OEM only. But to answer your question, they are 10mm x 1.25, 80mm long.

As far as where to find the rebuild kit, and the bolts, I would go to Extreme PSI.

They dont have the rebuild kit listed on their site, but give them a call, im sure they can get it. The part number is MB870511

Also, dont forget the factory washers to go with the bolts. Mitsubishi used two washers per bolt from factory as well.

Thanks for the part number for the master cylinder. I do plan to buy the ARP bolts from them, I saw those earlier, just wanted the measurements for reference purposes.


Would you by any chance have the thread pitch for the head bolts (7 bolt)? The engine I'm building for my gsx needs one hole cleaned out with a tap.

Do not buy the arp's for turbo to mani bolts! Use only oem the arp's suck for those cant handle the heat I guess. Plenty of info on here and the pain they cause. Arp's for sure for the head studs here's a chart for 1g but some may help you. http://www.dsmtuners.com/threads/what-size-is-that-bolt-nut-stud-fastener-1g-version.437697/

I would second that. I used the ARP bolts once, thinking the same way you did. I ended up breaking two turbo bolts and one to the O2 housing. I will not use the ARP bolts again for the turbo. OEM Mitsubishi with the double washers is the only way to go.

As far as your head stud, it is 11mm x 1.25.
