rusty260z Posted January 22, 2008 Share Posted January 22, 2008 My Aw11 Mr2 engine needs rebuild, got smoke and water in chamber, My budget/saved up is roughly $2,500 Aim - bought mainly for track use and one day Dunlop Targa etc. But has to usable on the road, dont want to tow it to track etc. Want something super reliable, but with potential to increase power later, power wise any gain over 30% above standard is swt (if that is realistic target) But have never rebuilt an engine and all work will be done by professionals / workshop, Will be keeping to supercharged, like having usable power from low in rev range. so do i keep standard supercharger or replace with something eles. So what do i need to do to achieve the above, what parts should i replace or rebuild, someone was talking to me about 'forged pistons' etc. so help me out with my budget. and spefic parts or part numbers or links would be super appreciated. thanks.

Spencer Posted January 22, 2008 Share Posted January 22, 2008 I wrote a big reply but closed the tab, anyway it kind of went 30% power increase on a good condition ze is sweet it will take it no sweat. Your budget only gives you scope really for a stock rebuild if you cant do much yourself. Quote Link to comment Share on other sites More sharing options...
rusty260z Posted January 22, 2008 Author Share Posted January 22, 2008 how much would be required for a decent rebuild. i.e with aftermarket parts Quote Link to comment Share on other sites More sharing options...
Spencer Posted January 22, 2008 Share Posted January 22, 2008 really depends what you want I think you really need to do some research but you dont really need to much aftermarket parts to make it go hard. A 4agze in good nick can make 160kw+ for along time. Start pricing up all the parts you'll need for the rebuild get some quotes for the machine work and go from there.

Dell'orto Posted January 22, 2008 Share Posted January 22, 2008 The stock internals on those AW GZE's are well solid anyway, the rods are massive and the pistons are "semi forged" and will take a massive beating. Unless you plan on making like 400+ hp, the stock stuff will handle it fine. Quote Link to comment Share on other sites More sharing options...
MkI_whiplash_Cortina Posted January 25, 2008 Share Posted January 25, 2008 Sounds like your looking for a bit of fun. From what I know and understand about these engines is that they are a pretty bullet proof. Here are the Ideas I have looked at when doing my rebuild on an AE101 4AGZE. I do have a PDF of an AW11 Manual if you want a copy just let me know . Your engine in a standard configeration is built pretty tough, the bottom end is very strong, the AW11 is the earlier engine and does'nt have the ceramic coated pistons, but if you want to replace pistons and rods with new ones you are looking at spending all the money you have in getting some after market forged ones where standard items would do just fine with the power increase that you are looking at getting too. I think you will find the AE101 pistons and rods will fit no problem these are a tad stronger then the AW11 and AE92.. From what I understand the weakest link for these engines is they throw rod bolts so the best place to spend your money is here by using a Set of ARP rod bolts they will give peace of mind if you want to push the rev's a bit, such as in the targa situation.. The other thing I would recommend would be to get a set of race bearings for your bottom end ACL do a pretty good set so get your machine shop to measure these. If you do that your standard bottom end will be more then adequate enough for what you want.. For your head you can look at putting some Blue top cam's from a 4age these have a slightly better lift which will give a little bit more power, and this will save you a lot instead of going for after market cams. You could get the valves re seated and possibly a back cut on them if you wanted. Where you will get your main power is changing the pulley for the supercharger.. So if you could'nt understand that long winded explanation simply.. ARP rod bolts (most important) can get a set for about $120ish off Trademe Big end bearings with race bearings ( or just new standard ones) $120 - 160ish Freshen up head with valve job and possibly blue top cams Also don't forget to get the guys to put in new seals on the bottom end and head, valve stem seals etc. Put on a new oil pump and water pump with all the new timing belts etc.. change the supercharger pullie's.. And most of your cash will be in paying the guys to do the job for you! Also look at http://www.club4ag.com, and here is a link to a technical section on these engines http://www.club4ag.com/technical_main.htm they have heaps of info on 4age's an AGZE's Have fun and any questions feel free to ask..

MkI_whiplash_Cortina Posted January 25, 2008 Share Posted January 25, 2008 Oh forgot to say, Stick with the Standard supercharger the SC12, you will find it a mission and very costly to fabricate a SC14 it has been done though. also maybe you could look at an aftermarket computer Mines did a good one years ago which made rev limiter higher and had a different fuel map which will help out heaps because these cars can rev all day.. .

CaMpylobacter Posted January 25, 2008 Share Posted January 25, 2008 wayne/vvega on here posted some time ago, i think, that sc12 are the better option anywho, more efficient or somehting Quote Link to comment Share on other sites More sharing options...

Mr Revhead Posted January 25, 2008 Share Posted January 25, 2008 buy a good running redtop bigport, a pully kit and a water to air intercooler (legacy or GT4) slap all the s/c gear on the redtop, install the IC do the ABV mod. away you go laughing then sell the dud 4agze longblock for prob what you paid for the redtop. and spend the $$$ you have left over on the suspension and rust repairs Quote Link to comment Share on other sites More sharing options...

MkI_whiplash_Cortina Posted January 26, 2008 Share Posted January 26, 2008 Unless you get the later 7 rib block the 4agze is going to have better internals hands down for what is needed to sustain30% increases... Redtop has different compression ratio too not best suited to forced induction.. Quote Link to comment Share on other sites More sharing options...

Redtop has different compression ratio too not best suited to forced induction.. yes the 4agze has better PISTONS, but its been proven many times that the bigports can handle boost. what i suggested is a good cheap and effective option that improves many aspects of the car. if the poster decides another option suits him better, fine. i will live. but he has asked for opinions. and they have been given. wayne... cheap remarks? your the one who launched into a failed attempt to get at me. again (jeez you really are obsessed with me arnt you ) as i just mentioned, my suggestion is a good one that would make a huge improvment over a stock AW11. ok he may not want to go that way, fine. but its still a good option. heres another good suggestion... GET OVER IT. you have tried many times to get at me, going to some pretty low, immature and rather under handed lengths of dubious legaility and you have failed every time. ffs grow up or are you going to get your flatmate to lay false complaints with my work again? i really wish you would just drive down here and look me in the eye when you spout off your bs in future please keep your petty bs off the forums. either ring me or come see me.
