twosrus is a good place for the ARP bolts. Never heard of a 4 layer headgasket. But then, I believe all head gaskets are layered. Though, I don't know how many layers an OEM one has. HKS,Cometic and TTE all make good headgaskets(in varied thickness' for different compression ratios) for the MR2.
What made the headgasket blow? That issue has to be indentified to prevent it from happening again. Good Luck.
true on that .. btw thank you i found the hks the best i'll be ordering that soon my friend just deposit my last check so i'm stuck for now.
on the matrixs forum i mention i replace one by one till i find the actual cause of it...
1. oem radiator cap $18.00
2. low temp termostat $21.00 plus $2.00 rubber ring
3. new oem radiator $433.00
4. new oem water pump $67.00
5. went thru four gals of 50/50 coolant $40
6. due to my time i had to pay labor for some of the install which totaled me almost $500.00 notincluding the time i got stuck on the freeway and lost a day of work.
and little white smoke is still accuring compression is 100psi which i read should be 150-180
its just making me sick not enjoying her i thought i had a good deal just wish i knew it had a over heat problem but i only found out it was bad when it was delivered which i was ashame to back out of the deal.
hate it ever since the mr2 was delivered to my house i haven't enjoyed her yet.
