4AGE Silvertop Rebuild, Turbo time... Options

[Xpander]

Finally decided to tear appart my spare 20v engine and build it up for a turbo setup. This particular engine has soooo much sludge its scary. I will update this thread with info and pics as I go. Enjoy.

sludge...where? i dont see it...its it that black stuff that looks like someone poured it into your topend? lol damn thats alot

and a 20v isnt the best for a turbo set up, 16v is.

good luck tho, hope to see some sick numbers

[Xpander]

I know it will be difficult to turbo, but I think I can handle it. I have a good understanding of whats needed....mostly money Gonna start with 4AGZE pistons and worry about rebuilding the head. Lots of to be done there. Toda parts aren't cheap.

How much PSI are you planning to boost your setup Colin?

The 20V is far better for boost than the 16V because it's a better breathing head and has more valve surface... in turn can more efficiently use boost. n/a wise... they're about the same overall...

Lot of degreaser GL with the project.

That's what I thought too!

[Silver94CelicaOw...]

Cool project.....a motor that responsive is gonna feel great when its been boosted.

Looks like the block and the head both need to be totally stripped down and hot-tanked or something. My spare motor looks similar, except where its sludge on yours its ash on mine. Good luck with the build, I can't wait to see it all done.

[playr158]

spray on oven cleaner is your friend!

and yea 20v higher VE then 16v.....

[WH95TE]

Goodluck!! Pics to keep us updated. and what Adam said, how much boost are you gonna run?

[Coomer]

Awesome Colin! I've thought about doing this when I'm out of school and on my feet.

What kind of head work are you going to do? And what about an ECU? And intake manifold plenum? I'm hungry for details.

Also, is your head the early AE101 version or the later version (with better flowing ports?)

[Xpander]

Not to sure how much boost I will run at the moment, need to do a bit more research as to how much a 20v with GZE pistons can handle...safely. I'll have to decide whether to get stock GZE pistons or try and go aftermarket. Rods are pretty strong to begin with. I'm sure 5-10 psi would be safe to begin with, after tuning a bit more.

For the cyclinder head, I was thinking of using Toda cams and gear(s). I plan on keeping the VVT and Toda has cams that will keep the system intact, just not sure what kind of duration/lift I want yet. A port and polish goes without saying. The engine is a '94 so I'm not sure if its the better model Coomer.....is there any way of telling them appart?

For the ECU, I was looking at megasquirt and also considering the Greddy E-Manage Ultimate. The Greddy unit (part. no. 15500501, 15901500) is actually supposed to work with the AE101 Levin, so we'll see.

The intake is just a matter fabricating something practical. I'll probably draw something up and give you an idea of my plan Coomer

More pics latter today of the tear down.

Wait, does this mean you aren't coming to the Ft. Laud. meet??

or are you gonna bring the Camry? I wanna see it

He's coming. He has a month and a half till the meet. If he doesn't have it finish by then, he'll definately have to bring the Alltrac Camry.

I'm putting this as nicely as possible.

If you don't know what you're talking about, don't try to give info on it! If you are unsure, then all you have to say is "I THINK.." before you start to type something. Although, many of us on here would just prefer to hear info from someone that absolutely knows what they're talking about. It is circumstances like these keeps myself, and many other people on hear from using this site as a source of technical info. While there is plenty of good stuff on here, there is just way too e-mechanics who spread mis-information.

how many 20v turbo 4age's have u seen?

how many 16v turbo 4age's have u seen?

(dont try to pull the rarity plug, because i understand that)

the 20v 4age is a torque monster, people use it more for NA set ups then turbo.

4agze's are even 16v.....

and as a personal thing, gtdriffter, im tired of u getting on my case about EVERYthing i put down. I remember at one point in time (for about a month) i couldnt post a THING with out u commenting either in the thread, pming me, or coming into the 6gc chat and telling me "what u thought"

4AGE 20V "torque monster"!? Heheh...

You can't compare the motor's based on "what you've seen" because you haven't seen it all. Mechanically speaking, the 20V is superior for boost because it has 3 intake valves with more overall valve surface. More valve surface, along with stock ITB's = more efficient use of boost because of better forced breathing. The 16V is not far behind, but it's behind.

n/a wise... they are equal because both engines need to spin to make power. If you match compression and cam profile between the two engines, they will make relatively the same power... with a slight mid-range edge to the 20V.

Also... the 4AGZE is a factory supercharged motor... yes... and are 16V... yes... but were also REPLACED with 20V's. That has nothing to do with how well either head responds to boost.

In other words... just leave it alone.

Lol, you guyz are funny!!! Sounds like there is some beef on 6GC!!! Now bak to the topic....damn you Xpander, I wish I can go turbo but I dont have the funds for it at all. My 20V isnt even dropped in yet because I dont know anybody who can do it for me properly!!! So im just trying to save my money up and send it to the main man Tweak. After I get it dropped in though, I think ima just keep it N/A and drop some cams, cam gears, spring, retainers and pistons and make an N/A beast!!!! But yo man, good luck on that. Bring somethin new to the site!!!

[uberschall]

i'm looking forward to watching this thread, gl with the build!
