Black or Silver :-\

[SCT]

I contacted a few people who were selling Silver and Black top 4AGE's, none of them are able to get the 4AGZE I wanted. One even said it's been a year since the last one that were able to get.

So now, seeing as the Silvers and Blacks seems to readily available, I may take up the offers.

However... Should I get Silver or Black? I was thinking black...

I'm planning on throwing in a good turbocharger. I have read somewhere the blacks/ silvers are not able to take as much boost than a 4AGZE. So I was thinking maybe get 4agze conrods and pistons... ARP bolts my friend told me about... Maybe get the ECU flashed, if I can if it's worth anything. And maybe if it matters or is possible, 250hp is my goal given the fact that my AE92 is only 90 something hp right now :p

Basically want to know the ups and downs between the silvers and blacks. What can and cannot be done, all the good stuff. I am a big fan of DIY and custom work and all, so if I have to route exhaust pipes up around over and back, I'll do it.

I would just find a gze long block or find a n/a 16v and dump gze pistons into it. Your going to be into more money to build a turbo 20v but yes you could throw in some gze pistons into a 20v as well. There is no "reflash" for the factory ecu there are some people that can modify the crystals or whatever it is inside the ecu but getting it done will be expensive and really not worth the results.

For 250whp you are going to need fuel/ignition control from something like megasquirt or the like. The stock gze computer can handle around 15psi boost or around 200whp with a turbo before it starts cutting timing.

I would start with a gze swap then go from there.

if you're going to get a 20V and then swap out the internals you'd be better off with a normal 16V. both 20Vs have high compression which is bad for turbocharging. Also, I know at least the blacktop block was lightened, so it's actually worse for turbocharging as well.

either try to find a 4agze or get a 7 rib 16V block and swap in new internals and be done with it.

also, with that horsepower goal, you really don't want to use a stock ECU. You're going to have to go stand alone.

I just realized you're in Maryland.

I just picked up my 20V from JEI last Saturday in Sterling VA. Send them an email and see if they can get you a 4A-GZE. They didn't have any Saturday, but they might be able to get some in, they have them on their website.

I just saw your thread, eage8, about your silver 20V.

The only reason why I wanted a turbo, just to have one (of course the nice boost it gives, done right). I can look pass not having one. As for 250HP, if my ae92 has exceeds what I want to feel, I'm fine if it's less than 250HP. I;m really not sure of myself

Maybe I'll just get a black.

Eage8, I found out about JEI on eBay and contacted them a few days ago about the 4AGZE. They were the one that told me they're weren't able to get one for almost a year now. I hope their site is up-to-date, I'll probably take the black off their hands.

From what research I have done, it seems that the Silvertop would be a more suitable choice if you're planning on turbocharging in the future.

[SCT]

What is the differences between the silver and black, besides year?

[eage8]

Blacktop has higher compression and lightened internals. I've also heard the block is actually lightened as well. It also has bigger ITBs, but you really don't need them any bigger...

this is a good reference:

When I was there on Saturday they had about 8 silvertops and maybe 5-6 blacktops to choose from, including 1 6-speed blacktop

[SCT]

After viewing club4ag, I might as well get a silver. It's more cost-effective for me since I don't have a large money tree. 5 HP difference, half a whole compression, no ribs!. And because the black is lighter, that really sounds like they scraped off as much unneccessary metal as possible from the silver, so that seemingly makes it less durable, I'm assuming, if I have the feeling to abuse. Pretty much I agree with PhatRoyale...

I'll be stripping the motor down anyways to clean everything, measure everything, fix whatever, paint, dress, kiss, hug, and what not. So...

It'll be maybe a month or two before I have more than enough money to buy one... But Yay!

250hp in an ae92 is useless...

the cars don't weigh much and if you're making that power either:

1) you have good power bands and have no traction
2) you have traction and all of your power is up top

I say get a blacktop or go find a gze..... silvertop is a waste since they only produce about 10whp more than a smallport 4age.

[SCT]

What's the WHP in between the latest 4AGZE, Silver top and Black top?

[toyotaspeed90]

the 4agze will put out quite a bit more torque.... so, unless you're always driving at 7,000 rpm's there's no comparing it to the 20V's for power....

ST will make roughly 120whp and BT's, if you're lucky, will make around 145whp.

[Croatian_AE92]

this is just want i think from what I've read. you want 250 hp, thinking about using stock ecu. you want it turbo, want it available. One engine you should consider. 3SGTE, get the right gen and you'll have 250hp stock, turbo, and its available, how ever it will be more costly and it doesn't drop it. However it have been done. just a thought

[SCT]

I've thought about the 3STGE, from an ST205 Celica, but, yea, it doesn't drop in like the 4A motors. That will be my future motor, though, when I get buku money. For that motor, I'll probably set my hp goals higher
