7age bottom end

[DR86TY]

Hey guys,

Was looking into the 7age bottom end for my ST 20v.

Does any one know if this is a straight bolt up or would i need plenty of back and forth to make this work.

Cheers
Dave

You need to deck the head, pm grant from syd section his just done a blacktop 7age buildup

It's a 7afe bottom end

Can't help you sorry. 7oxin would know.

mkae sure if you get the motor from the wreckers you at the very least pull it down and inspect it, if not give the bottom end a solid re ring and maybe even bearings... to really maximise the fatc it is an extra .2 ltrs i would suggest an aftermarket ecu aswell

Yeah, the 20v head will bolt up.

No real need to deck the head, you'll get enough compression from the 20v head, and 20v pistons. If you need a little more run a TRD HG.

Thanks guys,

Just looking at my option as my ST is blowing a fair amount of smoke and dont really want to rebuild the 20v as i might be converting to a turbo setup in around a years time.

Thanks again guys.

if your going turbo not really any point doing a 7age unless you plan on getting quolity parts off the mark. the head will bolt strate on i would still get it decked to insure it will seal perfectly with the 20V head its like $50 or so and well worth the money. and if you are going to drive it hard then you may as well cet new rods now cause it is cheep insurance.

does your motor still pull ok? like power?

cos its a pretty common thing for 20vs to "wear out" valve stem seals. which is where the oil smoke could be coming from.

either way, even if it is the bottom end, youre gonna want new rings no matter if you keep your bottom end, or go 7a, if youre current set up blows a lot of smoke.

Still pulls fine,

The smoke has gotten worse but no power drop, and eating through a fair amount of oil.

If its just valve stem seals, all i need to do is recon the head??

[slydar]

yes.

get cams to

but seriously at some places adding aftermarket cams wont add any extra expense to a head reco, as they will be setting the lash anyway.

just something to think about.

other thing though is a full reco' might not be really necessary (eg valves lapped etc) just replace the seals.

anyway.
