1st_rolla_ke30 Posted April 20, 2009 Report Posted April 20, 2009 hey guys I'm looking to buy a 4age but not sure if big port or small port it is out of a late ae92 with silver cam covers and black writing please help so i can choose thanks michael Quote
trav_555 Posted April 20, 2009 Report Posted April 20, 2009 Hope this shows you the answer man :jamie: Travis Quote
towe001 Posted April 20, 2009 Report Posted April 20, 2009 Somethings a bit screwy there cause i always thought the bluetop made the 88kWs and the TVIS redtop made a bit more. And you missed out the very first generation "Blacktop" Quote
parrot Posted April 20, 2009 Report Posted April 20, 2009 And cam covers are not a reliable indicator. Waits for first post that refers to them as rocker covers..... Quote
trav_555 Posted April 20, 2009 Report Posted April 20, 2009 Thats the best photo i have It more shows you which engines are the smallport and bigport versions right? and which model they came in? Its just a photo i got shown which i thoguht was handy to have :P I didnt make it and never looked into how accurate it was either Travis Quote
parrot Posted April 20, 2009 Report Posted April 20, 2009 Absolutely Trav, I knew where you were coming from. And it is a good general guide. Just making sure Michael knows to delve a bit deeper when he susses the motor out. Quote
trav_555 Posted April 20, 2009 Report Posted April 20, 2009 (edited) No worries By the way, from what i gather Is it the blue tops in that picture that are bigports? and the redtops that are smallports? but wasnt there some kind of 3 rib smallport? And some 7 rib bigports? Travis EDIT: Also you know usually its a bigport or small port because of tvis right :P Edited April 20, 2009 by trav_555 Quote
parrot Posted April 20, 2009 Report Posted April 20, 2009 Should add to answer your specific question. If it has TVIS it should be a bigport, no TVIS it is a smallport or someone has taken the TVIS off....... But that is probably unlikely. Assuming the engine number matches the car, simplest way to tell is from the spark plug valley cover. Bigport leads enter above each plug, smallport leads run underneath after entering at the front of the head. Quote
parrot Posted April 20, 2009 Report Posted April 20, 2009 We crossed there. Earlier bigports are three rib, in rear and front wheel drive. There are later 7 rib bigports, all front wheel drive engines. Positively no 3 rib smallports. Quote
trav_555 Posted April 20, 2009 Report Posted April 20, 2009 Sweet well surely all that information should be enough for him or anyone to figure out if there buying a smallport or bigport engine, i would assume so at least unless someone has something else to add Travis Quote
Hiro Protagonist Posted April 20, 2009 Report Posted April 20, 2009 Somethings a bit screwy there cause i always thought the bluetop made the 88kWs and the TVIS redtop made a bit more. ADM bluetops made 86kw in the AE82 (and early import AW11s). The 96kw number is from the JDM AE86s. Supposedly series 3 ADM AE82s had the 7-rib bigport, which definitely had 88kw (same engine came out in AW11 MR2s, and early JDm AE92s) And you missed out the very first generation "Blacktop" Didn't think there were two blacktop generations (assuming you are referring to the 20v). Silvertop has two generations, you can tell by the number of throttle linkages. Quote
drc_ke20 Posted April 21, 2009 Report Posted April 21, 2009 well done trav 555 for that handy illustration/pics you put up! Quote

Supposedly series 3 ADM AE82s had the 7-rib bigport, which definitely had 88kw (same engine came out in AW11 MR2s, and early JDm AE92s) you answered a question that has been bothering me. my KE25 has a JDM sprinter engine and i was always thought it was the 88kw engine but the guy i bought it off said it was the 100kw engine, I'm guessing he just rounded up the killawasps Quote
Hiro Protagonist Posted April 21, 2009 Report Posted April 21, 2009 you answered a question that has been bothering me. my KE25 has a JDM sprinter engine and i was always thought it was the 88kw engine but the guy i bought it off said it was the 100kw engine, I'm guessing he just rounded up the killawasps Or he didn't know what he was talking about. Quite a few of those out there. Quote
LukeAE71 Posted April 21, 2009 Report Posted April 21, 2009 Didn't think there were two blacktop generations (assuming you are referring to the 20v). Silvertop has two generations, you can tell by the number of throttle linkages. So what are the other differences between 1st and 2nd gen silvertops?? I ask this as I am currently installing a 2nd gen and just curious?? :P Quote
