ok i have had my gs for a year now no mods besides sound system.
about to hit 200k miles but seems like it doesnt even have that much at all it was fully maintained by an old lady by the dealership,

only thing im about to really do is do all my gaskets fluids and headstud the motor prepping to boost it since im going to have a decent amount of down time to work on it anyways my question is

i want to go with the gte head gasket is there a difference in the vvti and no vvti head gasket?

and is the best way you think i need to go with i want to get a full headgasket kit or would i need to piece it together ? And, i also planning to change the front and rear main seals and vvti cam gear seal anyone know if powerdynamix still selling it?

i will also be going with a trans go / valve body upgrade planning to try to hit 350hp daily
i was also pondering if i should go with shimless buckets since the head is coming off .

 

I believe there is a comtic metal headgasket. I would look into that.

 

im trying to stay with OEM so is there any answers to the vvti gte head gasket vs non vvti?

 

Just buy a head gasket kit for a 98 Supra TT. It's the only year where the GTE was available with vvti in the U.S. Pull your head off, send it out to be checked and cleaned and replace anything you think you need to while the motor is apart. You'll be good and ready for boost .

 

as far as vvti vs non vvti I can't help you with that, but on the SC forums most favor the OEM GTE HG's

smh kinda bumped a dead thread. my bad.
