what exactly is 1 and what advantages deos it have over a standard block, and deos any 1 have any ideas how much it costs ?

cheeRS fellas

 

From my enquiries it is a high power mod ie 350+ and is supposed to give a stonger fix of head to block it came from the WRC enviroment i think it costs about £350 as the block has to be machined as well as the cost of the studs. PJ Motorsport could give you a price for all. I have used the ARP stud kit myself £125 which are a big improvement on standard but i only intend to run stage 1. regards ED

 

ive been longg studded!. the people to contact are mountune racing. cost is about £300 and you get holes drilled through the middle six bolt holes in the face of the block into the main bearing housings. special double ended studs which have O rings fitted in the middle are supplied for these holes (there are pictures on mountunes web site). the standard bolts are used in the end 4 holes to hold the head on.

im told... the benifit of these is that the possibility of cracking across the face of the block is eliminated and a greater clamping force can be applied to the studs than can be applied to the standard bolts.

another benifit is that there is no need to use a torque plate to bore because the distortion introduced by the bolts picking up on the original bolt holes which are in the block face is gone.

one thing to consider if you get this done is that a 2wd head needs the original holes (where you enter the bolts) machining out or you cant get a socket in to tighten the nuts up on the studs. this is EXTREMELY annoy ing to find out at 9pm when ya on a roll and think the car will be on road tommorow cos ya gotta fully strip the head down to get it done then clean all the swarf away after

 

the mountune long studs dont come out the bottom so i dont what you bought

a machined down socket will fit fine over the nut!!

the block isnt drilled into the bearing housings either.

thanks

 

Sorry Swerv, but PGt's description is damn fine if you ask me. Admittedly the studs are threaded into the crank webs, but thats nitpicking, his description is good enough for me in all aspects.

 

thanx stu - ya been there at 9pm yourself then?

 

yeh thats what i meant , it dont go down to the bearing housings .

which was what i stated , nothing more nothing less
