mk2 gt Posted February 24, 2007 Share Posted February 24, 2007 all right guys i would post this on toyspeed, but i cant join as they dont allow hotmail accounts, so i will ask here i have just picked 2 blocks up they are 4age blocks, i have a feeling they are different and maybe not bluetop. The numbers on one of the block are - o11 and y29 with a k after it and the other is y20 o22 does any body know what one is what? i think one might be a red top block and the other a 4agze block, as i got a 4agze intake manifold and one(or half) of a red top rocker cover(there is 2 rocker covers on red top 4ages) i also got a head with them and it is a wide intake head is there any way i can tell? all help much appreciated Quote Link to comment Share on other sites More sharing options...

mikuni Posted February 25, 2007 Share Posted February 25, 2007 I dunno, but you should put '4age' in the title. Will have all the toy geeks clicking on the thread. Quote Link to comment Share on other sites More sharing options...
CUL8R Posted February 25, 2007 Share Posted February 25, 2007 If you want, flick me a PM and I'll sort you out with a GMAIL account if you want?? Free, but 100x better than hotmail, shit loads more space, and Gmail should be accepted by toyspeed.. Cheers,Chris Quote Link to comment Share on other sites More sharing options...

Spencer Posted February 25, 2007 Share Posted February 25, 2007 basically theres only 2 blocks 3 rib from bluetops and 7? rib its easy to see on the other side of the block. Doesnt realy matter does it anyway? theres nothing special about the ZE block i also got a head with them and it is a wide intake head is there any way i can tell? all 4ages are wide two cam gear types, single gear type = 4afe. put up a pic and ill tell you what youve got. Smallport ftw if going n/a 16v Quote Link to comment Share on other sites More sharing options...
mk2 gt Posted February 26, 2007 Author Share Posted February 26, 2007 i have a twin cam head sitting in storage and it is wide port as its just the head and i can see the ports. i do not know what i have on my blue top but i believe its small port. doesnt the 4agze have some forged internals? there is something about the block thats stronger Quote Link to comment Share on other sites More sharing options...
70MK1 Posted February 26, 2007 Share Posted February 26, 2007 Bluetop are big port. ZE's have forged internals & come in both bigport & small port. some 4A blocks have 3 ribs, some 4A blocks have 7 ribs, 7 ribs are believed to be stronger. Have a look here http://www.club4ag.com/technical_main.htm Will give you some good info Quote Link to comment Share on other sites More sharing options...
Spencer Posted February 26, 2007 Share Posted February 26, 2007 ZE's have forged internals & come in both bigport & small port. big missconception, pistons are semi forged or sqeeze cast or what ever you want to call it (<- over my head) technically not forged. And after they went to the big crank all rods of the same year of production were the same and cranks the same. And wide intake I thought you were talking about valve angle as in the difference between fe and ge heads sorry. easiest way to tell waht head you have for a noob is count the intake runners. 8 for bigport and 4 for small Quote Link to comment Share on other sites More sharing options...
70MK1 Posted February 26, 2007 Share Posted February 26, 2007 Spencer - stop being so dam quick to point out my mistake After a smoke & coffee to wake up, I realised I was thinking of something completely different cheers for pointing that out Quote Link to comment Share on other sites More sharing options...
mk2 gt Posted February 26, 2007 Author Share Posted February 26, 2007 i have 8 runners on the engine in my car but the extra head i have in storage doesnt have intake runners on it, the intake runners i have is for a 4agze and there is only 4 of them i know its 4agze because it says 4agze on it Quote Link to comment Share on other sites More sharing options...
danger Posted February 28, 2007 Share Posted February 28, 2007 We used a 7rib for a 4age turbs cause they are the only ones supposed to be strong enough to handle any decent boost. Quote Link to comment Share on other sites More sharing options...
Spencer Posted February 28, 2007 Share Posted February 28, 2007 We used a 7rib for a 4age turbs cause they are the only ones supposed to be strong enough to handle any decent boost. ever seen anyone pop a block on a 4age that wasnt a leg out of bed? doubt your ever going to do it from cylinder pressure even on the 3 rib. Seen a few stock internal bluetops boosted up 170kw etc Quote Link to comment Share on other sites More sharing options...
rob Posted March 15, 2007 Share Posted March 15, 2007 if you havent found it already, this page: http://www.billzilla.org/4agstock.htm has some good 4age info - especially if you need to work out what kind of 4age you've got. theres pics of the different port designs about halfway down.. big port is quite wide and flat compared to the smallport. also smallports have an oil return at the back of the head on the right side - if you've got one of these you'd probably want a smallport block so its got somewhere to plug into, plus those extra ribs cant hurt ive got a smallport sitting in a mates garage and could get you some pics of the block/head if you want Quote Link to comment Share on other sites More sharing options...
Mr Revhead Posted March 21, 2007 Share Posted March 21, 2007 ZE's have forged internals & come in both bigport & small port. big missconception, pistons are semi forged or sqeeze cast or what ever you want to call it (<- over my head) technically not forged. And after they went to the big crank all rods of the same year of production were the same and cranks the same. theres the missconception there they ARE forged. semi forged = impossible you either forge something or you cast it. and the 4agze ones are forged. hypertutectic forged pistons is what they be. where the "semi forged" comes from is they arenot cold forged the slug is heated so its soft, but not molten then forged. 4age blocks arnt weak, so a bigport block is no problem unless your after 500hp when maybe some block warpage MAY happen.

Spencer Posted March 21, 2007 Share Posted March 21, 2007 Im from toyspeed and have been in the debates fully agree with you on the semi-forged call was just being lazy. semi-solid forged is abit more on the money and hypereutectic is just refering to the alloy mix but you know all that. My bad, realised what I posted after the fact and never changed it Quote Link to comment Share on other sites More sharing options...
Mr Revhead Posted March 21, 2007 Share Posted March 21, 2007 sweet as. we all do it! i just did, by not explaining hypertutectic Quote Link to comment Share on other sites More sharing options...
