Hey i will be doing a mini me swap and i am trying to figure out if i can use a Z6 rebuld kit on my y7 block since i will have the z6 head and valve cover or should i do a y7 kit even tho i will have the z6 head?

Im kinda new to this

 

Are you talking about a master rebuild kit? If yes - get the Z6 and buy whatever doesn't fit separately, provided that you already have the z6 head.

 

I might sound dumb but i was just going to get a basic rebuild kit lol is there a diff with the master rebuild ?

 

pay attention to whats included in the rebuild kit your looking to buy and make sure you know what parts you want in a kit. basic kits are just that just a freshen up kit basically. master kits will have more parts included in the kit along with the same parts in the basic kit. just think basic kit = freshen up master kit = overhaul. also there are plenty of brand kits out there and they done all include the same thing.

 

yea my engine has 198k so i wanted to rebuild it so itll last me since it will be my daily i wont be doing much racing its more for show and its cheaper I guess, but would you recommend a master kit over the basic for long haul driving ?

 

your big items will be valve seals and cam and rod bearings. piston rings are fairly important also but they usually come in both kits i believe. your other big item is timing belt and tensioner, water pump and oil pump. timing kits are generally sold separately but whatever kits includes what i mentioned.

 

Ok awesome yea the rebuild kit im getting has all that except the cam and rod bearings i think.

another question can i use a Y8 trans on the y7 block with the z6 head ? Im having alot of trouble trying to find a z6 trans and for the y8 ive found like 3

 

Yes you can use a y8 trans, but it's been so many years for me I don't remember if the speed sensor matches. Probably does, if not - use a Z6 one.

Before you go and order stuff how about actually taking the block apart and taking a bunch of measurements to see if all you need is a re-hone or possibly a bore out with the next size up pistons. Make sure you check the cylinders for being out of round on top and about mid-way down. All of the specs are found in any good manual for your car.

 

Awesome thank you so much brother and i will be taking the motor out this week hopefully wednesday and ill start taking everything apart and will do all the measurements

 

Also make sure the crank is within spec. It is possible that you may need a crank grind and one size up mains and rod bearings.
