location : sydney

ride :94 EF XR6 trans : BTR 4 SPEED AUTO

budget for engine $2000 parts

goal: free flowing , smooth reving reliable engine ( not looking for big power)

advice needed :
* ok i need advice on the best but cheapest parts.
* trouble you have come across and advice on how to steer clear from it.
* advice on what you would do with the money and how u would build it.

remember im not looking for power just reliability and i dont want just a engine clean up i want new parts from head up.

also im getting a new btr 4 speed , new spark plugs, jmm extractors ,hi flow cat and 2 1/2 inch piping.

i just want some help so i get good parts and dont get riped of by any one

thanks guys ill be posting about my btr 4 speed on the transmition section.

Get an EL GT intake snorkel for about $35 from Ford. No trouble with that just straight swap fits perfect.

Get a 3" intake pipe from the airbox to the throttle body. Should be about $300-$350 from an exhaust shop. Problems with that is it might rub on the bonnet so you'll have to check for clearance. Maybe get the exhaust shop to flatten the piping a little on the highest point.

Finally get the head off and get it ported and get new valve guides, valves. That'll be the rest of the money gone.

Free flowing engine then with the JMM extractors and exhaust system.

thanks but i need to know more about some after market valve springs and valves , and how much ruffly ?

if you not after power then i would probably look at a acl bottom end, either standard rebuilt or maybe step it up to a race series. A race series rebuilt kit is around the $880 mark not including labour and machinging. I bought a acl race series bottom end few months back and i think the guy said it cost about 1300 built. and that will be a nice and reliable bottom end the with the leftover $700 i dont really know what u could get done to the head? maybe just look for a very low km au head and bolt it on? that should provide you wil a bit of extra go and decent reliability.

Get:

an ACL RACE kit
Aftermaket cam, surecam do good ones
Appropriate valve springs if required
Vernier gear, install as per cam grinder recomendations
Get the head and deck skimed slightly
Full 3 angle valve and seat job on the head
Better intake as described above.

Thats it without going into the ecu side of things which starts to get pricey and keeping under $2000 parts budget.

Heavier springs are normally only needed for more rev's and aggressive profiles. Heavier springs can cause mechanical losses. The EF runs thinner valve stems and beehive style springs IIRC and thats good enough.
