Hi,
I plan to change my old 1996 corolla AE111 (4A-FE) engine, because the fuel consumption is bad. 350km on RM60, with 70% highway driving! I still plan to use this car for sometime more. Plan to get something which is plug-and-play w/o much hassle. Is this advisable?
I read in this forum, about the difference in engine @ http://www.club4ag.com/faq%20and%20tech_pages/4A-GE_technical_specifications.htm
Which engine model is the BlackTop (BT) and SilverTop (ST)? ST is superchange right?
What other engine choices do I have?
Is MAF better (fuel consumption) than AFM?
Both these webpages below is also something I found in this forum, but it is in japanese.

Info based on this forum discussion so far :
1) There are 3 types of engine that will fit.
Here is a quote by http://www.zerotohundred.com/newforums/member.php?u=18002 :
ST + Installation = around RM3500
BT (5 Speed) + Installation & SC + Installation = around RM 4500
BT (6 Speed) + Installation = around RM6000

2) AFM is better than MAP. AFM can rev higher. 'http://www.zerotohundred.com/newforums/member.php?u=17782' has problems with his AFM, as it spoiled a few times already. A quote from http://www.zerotohundred.com/newforums/member.php?u=18002:
MAP vs. AFM
Not really, the only reason the Japanese versions of the early 16V 4A-GE came equipped with MAP sensor (vacuum sensor) control is because it was much cheaper to equip, keeping the cost of the car's purchase price down. The USA versions came with the AFM ( air flow meter) because it can monitor the intake air somewhat more accurately in that era of technology...and thus was required to meet California's smog regulations. Both units work equally well and the only sole advantage to having map sensor controls is the fact that induction chamber modifications are somewhat easier without the bulk of the AFM unit. The performance is in no way significantly better though as many believe.

4) Problems with SilverTop
5) Other info :
AE101 vs with AE92 (non-tvis), AE92 non-tvis are more powerful
Very useful info about 4AGE history at http://www.users.bigpond.com/vidore/toyota_4age_engine.htm
The 20-Valve 4AGE replaced the 4AGZE Supercharged engines. Just like the early and late 16 Valve 4Ges, they also underwent revisions. The Silver Top was introduced in the Corolla AE101 (1992), and the Black Top in the Corolla AE111 (1997). Both engines used Toyota’s version of Variable cam timing- VVT.
