help my 20v blew up, fixing alternatives?

[lost]

Hey guys, as no one cept sanxta will actually no me, I guess I'd better introduce myself heh. I've kinda been around for a while, just never really post, more learning as much as I can, I am the proud (haha) owner of a 20v silvertop in a 94 trueno ae101 (non-facelift), which when purchased (bout 6months ago) I'd planned to mod, but every 5 seconds something else has been going wrong with it, and it's finally gone (only like a few months after buying it lol; clocked back obviously, as it's reading 77ks heh), ive burnt a valve or dropped a piston or somethin, either way, shes runnin on about 2 cylinders, 70pounds compression in number 1, havent checked the others, looks like shes dead though.

Now since its gonna cost so much to rebuild the damn thing, and it had already had the head gasket done and the head never came out fully straight, I don't think it's worth it.

SO, since I'm looking at some horrible damages of round $2-2500 anyway, and unfortunately, while I want to learn as much as I can, at the moment I really don't know jack above the very basics in the engine department, so the work is going to have to be done by someone else ($$$). Anyway, back to the point...

How easy it is going to be to drop a 4AGZE in it? Because then at least I can hold onto it and save for a turbo conversion. Also, assuming I pick up a 2nd hand engine from wherever (dodsons, toyotaz galore, engine imports or what have you), are they reliable engines? I really don't know much about the 4AGZE, and haven't previously owned a FI car, only NA.

Also any idea of the sort of expense am I looking at in the future to convert it to turbo assuming I'm probably going to have to pay for a fair bit of the work? From what I've read from around here I'm looking at another 2-3grand depending on how much power I'm looking for? Do the boxes match up from the silvertop and the AGZE? I'm thinking they don't, which might put the conversion out of my budget if I'm gonna need to get a box as well. Any help I could get here people would be fantastic. Sorry if I'm asking a lot, I know I am heh, but I'm kinda up shitcreek without a paddle at the moment.

Thanks heaps Guys :)

i do believe(correct me if i'm wrong) a 4agze will drop straight into the levin but you will have tp cert it because you have gone fron n/a to forced induction
as for the rest of your question i wouldn't have a clue

[PumpN]

why not just get a 20 Valve long block and slot that in if your after getting it back cheap, dont see a long block costing more than $1000, then all you have to do is swap all your bits over and bolt it in, would certainly go better than your previously trashed to death then probably clocked back engine

Sorry I'm still working in lamans terms like I said, I'm pretty poor on my knowledge of engines aye. But If I've burnt a valve or whatever getting a new block wouldn't solve the problem would it, cause I'd still need to have the valvetrain/head rebuilt? I'm still not sure of what exactly has happened, but it's probably not possible to find out without actually taking the engine apart, which = $$$, and it seems clear its actually shot this time :/

[IFSN8U]

Sounds like you have some funtimes ahead.
i recently stuffed my 92 fxgt up. I decided to put 4agze in and turbo it. im in the process of doing it now.
you sound like me cause i knew jack shit as well when i started out trying to figure out what i was gonna do.

to answer some of your questions the 4agze will bolt staight in to your trueno.
yes you can then turbo them

you just gotta decide what you wanna do fix ur motor, put the same one in or upgrade to supercharger.
Just depends on how much money you got and what you want.
i'd recommend if you don't have too much money look at either fixing the pproblem or get the same motor and put it in sounds like urs is a bit of a shitta.

gtz levins had a 4agze from factory ( u should have bought one of these)


try to find a crashed one of these and get all the stuff of it

u need :
ecu
gear box
drive shafts
cv s
engine (of corse)
wiring
brakes (maby)
Bonet (maby)
cert

just to list a few

a long block is the term a wrecker or toyota would use to describe a complete engine, just minus electrics like dizzy and all your ancillerys like alternators etc ..., its got everything you need (and everything it doesn't have can be pulled off your old engine) and they work out much cheaper than a front cut or an engine rebuild

Ahh I see cheers pumpn. Ye I know the GTZ's had a 4AGZE from factory, but at the time I wasn't really considering FI. I've been given a few quotes of around $1000 for a new 20valve, obviously without loom, computer, box.

Any idea then IFSN8U or anyone else what sorta damage I can expect to do a turbo setup on a 4agze from now. I have around 3-4 grand, so if it's a possibility I'd definitely consider it as all other aspects of the car are fine.

Also, anyone know what sort of prices and how easy 4AGZE's are to track down? I rung a couple of places today but they reckon'd they were too old to get now. Dodson's had them around 1400+gst though minus loom, box, comp etc.

[Loudtoy]

Uh if you have a quick look in the general discussion section there's a bit in there about changing a 20 valve to gze - was basicly decided that in the end it would be cheaper to sell the car and buy a gze straight out! Changing a motor even to one from the same family is always a big job and never as straight forward as you think! Best thing i can think of to do would be to redo your motor or buy a long block as pumpn suggested and with the extra money slot some forgies in there in preperation for forced induction at a later state!
Or you could go a different way than everyone else and stay na, maybe??

4AGZE's are very rare now and so are very expensive. Occasaionally you come across a cheap one thru a mate somewhere or something but if you go looking for one about $1500 is normal.

Allow another grand to get it in and going and another two - three to turbo it. (these are not quotes just from what i know of people doing similar jobs)

[Lanius]

If I was you, I'd do like Loudtoy suggested and stay NA. Theres something appealing about a high-reving, powerful NA engine (Group A anyone? ) ... and its even better when they match forced induction vehicles.

You could always try to source a blacktop to fit in place of your silver ...

[Mr Revhead]

yup matts right $1500 is a cheap price for a 4agze now. i should be able to get you a complete 20v for under a grand though,
just send me an email when ya know what you want:
warwick.parts@bowater.toyota.co.nz

also staying with a 20v means it will be basicly plug in and away you go.
nothing at all wrong with 20vs
