i dont really agree with you dave on the "4age's are good,but not that good"
3s is a stuff load more work then a 4a conversion, by the 1st post you can tell the guy is going to need quite a bit of help.

everyone is on the 3S bandwagon now - 4ag 16v engines rock!

Cicca - if i were you, id just keep the thing auto.. work hard, save some pennies, and do a 4ag conversion, 16v or 20v

engine cost can very depending on how you go about it.
you can pay up to $2800 for a low Km mildy modified 16v engine. (that what i sold mine for)

T50(JDM) $250 - $350
Ae71 pedal box - $200
ae71 clutch master - $30-$40 or so
ae71/86 clutch slave - never brought one $? about the same as the master i guess
Clutch hard line - could get from a wrecker or make your own
clutch flex line - local brake shop can sort you.. $25?
ECU and loom - depends if u stay stock or aftermarket
ae71 tail shaft - $100?
JDM 86 EFI fuel tank - $300 - $400
ae86/71 engine x member $100 -$150
ae71 gearbox x member - $40 - $50
Extractors/Exhaust - $800 ish

Fuel lines - Wiring - misc - $200

if you cant wire it up yourself then maybe $500 - $700 to wire it all up? im just guessing that as ive never had to pay for it.

i am missing stuff but you get the idea.. it all ads up and its the little things you usually dont think about
