You often have to go to a referee when you do mods like this. Typical motor swaps must be same year or newer, not gas to diesel, and have that motor's smog equipment. Naturally, the heads would be off an "(insert year of your truck )" making the motor the same year as it started out.

This falls into a bit of a gray area. You might just pull up to a smog shop and get a passing visual inspection or sent to a ref. While you won't have the performance of headers using Camry manifolds, it would probably save money and you'd get through the smog test easily as it's normal to replace the pipes as they rot out over time.

Would headers off of the 5ZFE work?

I had wondered that myself, or even the manifolds, but I have research it to know. I'll look into it.

 

You would also have to remember that with a 5vzfe intake you will need to relocate the battery to the driver side instead of the passenger side like the 3vze.
And on a 3vze, which way is the engine pointing? like is the "front" with the timing belt pointing towards the driver side or the passenger?
And if it's driver side (that's what fwd is right?) would the intake not come from the front or right side of the engine, so you can use it instead of a 5vzfe? I'll try to get some pics of it to see if i'm right...

 

Ah yes, i'm wrong....

 

Dan - I was reading up and you recommended the 4a-gze injectors saying the 7m-ge injectors were too big, but from everything I've read the 4agze injectors are bigger. 365cc vs the 295cc for the supra injectors. This makes sense considering the 4agze was a supercharged engine. Just thought I'd let you know the results of my research.

Also for everyone else remember when trying to get some of the th 7m-ge supra parts, that engine was also in the cressida.

 

Just found this helpful page

http://www.toysport.com/webpages/Tec.../injectors.htm

According to this our injectors are 200cc, 4age 210cc, 7mge 295cc, 22rte 295cc. I'm not sure if the extra 10cc would make enough of a differences to justify swapping the 4age injectors and but it may be our only choice if the 7mge injectors are too big.maybe if I can save up some money this fall I can try some of this stuff out.

 

You know what we should do here? Start a paypal fund for Dan to get this swap underway and finished! I'd be MORE than happy to donate $5 or something along with others interested in this swap to see that it actually works. Anyone else agree with me?

 

I'm in!

Good idea Adam.

 

Count me in 2!!

FINALLY some of my ideas from over a year ago are being discussed!!!

Namely the '82 Supra VAFM combined with an oversized TB.....

Any ides if the ECU could compensate for the more air coming in giving me more power and mpg?


My engine has 251,000+ miles on it right now, so she's kinda fragile and I dont want to do anything to hurt her right now....

 

I'd have to go back and read where I said that. I think you might have misread what I wrote or I was half asleep when I wrote it. What I said or meant to say was this. The 7M-GE injectors would be a good upgrade for someone wanting to upgrade the injectors. If the S/C does work on the engine after using the 5VZ-FE intake, I'd upgrade to the 4A-GZE injectors. I was saying that the early 7M-GTE injectors will physically work (connector and independance), but I think that they would be too big unless going with some big boost pressure (which I wouldn't advise).

 

You guys on this board are awesome. Just the thought of support like that is great.

 

I'd donate to that cause myself.

By the way, I got on eBay and did a general search on AFM's. I noticed that most of the late 80's and early 90's AFM's looked alike...So I wrote one of the Mazda RX7 sellers and from his pics and description, the AFM would pretty much drop in. Plus, it's throat is 2.5 inches square (his measurement) ....or about 5 square inches of cross-sectional area. That's about 66% larger than what we currently have. It probasbly wouldn't bolt up to our air box, so a new filter arrangement would have to be fitted.

The current bid on these is about $20 plus $10 shipping. I was trying to steal it for $5. I'll keep watchin' and let y'all know.

 

you could get a cheap summit cone filter fab and adapter and a heat shield

 

I'm in for the fund! Everything so far sounds excellent about this, and this could be our "community effort" that we could all participate in. FWIW, I'd already be buying up parts but am unsure about the timing belt issue. I just can't have the truck down for very long. So Dan, if you don't mind sharing, what kind of cash flow amount do you need to really do this up right?

Me too! Just consider it R&D funding Dan. What's your paypal address?

 

He said 4agze injectors, not 4age 2 different engines...
And i'd give 5 bucks....

 

I know. I'm just saying 4age would be a much better fit than 4agze for N/A engines.

 

Also a nifty side effect of all this work that hasn't really been mention is that the fe runs 9.6:1 compression while the e runs 9:1. The bump in compression will help hp and gas. For every point of compression power improves ~5% and mpg improves ~10%. Personally I'd love to bump the compression up to 10:1, however, other than milling the heads or custom piston work it'd be hard. Personally I frown upon milling heads to increase compression and custom pistons are $$$.

 

ok, guys, here is where I'm at.

I have the engine obviously. I have the entire intake and TB. I have 2heads from the same side which I'd gladly sell or give to one of the people that contribute to this project if that's the way we're going with this. The heads are interchangable.....you can use then on the left or right bank, but you have to swap cams which is pricey for new ones. So anyway, I need one new head. I just bought new rods to be on the safe side. I have the rebuild kit. I have the pistons.

Basically all I need are the injectors, valve covers a new head and have a machine shop cut me some header flanges. Doesn't someone on here have a machine shop? That couls be a good contribution to this project.

I'd also like to have the head rebuilt to ensure success on this project. I might have the speed shop that we work with build the short block because I'm using Total Seal rings and I was told by a friend that they still have to be set right. I figure that they would have more experience with these rings than I do. Maybe I can watch and see how they're suppose to be done.

Anyway, I couldn't tell you a price without calling the speed shop. I'd say $75 for another head, $30-40 for valve covers, $0 for the injectors if I can find them in the salvage yard, and if someone can make the header flanges I have the pipe to make them. Then there is still a possibilty of timing bely guess work.

I'd say $300 as a good guess for parts, head rebuilds and short block build. Maybe more or maybe less. If that much is raised and it's less, the extra money will be given to the next person ready to do this swap.

My paypal address is djvilleneuve22@hotmail.com if you guys are serious about this. I have one stupid question though......how do I get the money out of this account? Do I have to upgrade it? I just have a basic account. I only use it to buy things on ebay so don't know a whole lot about paypal.

 

Sorry for the triple post but on a totally separate note. If we use the 5vz-fe intake won't we have to use the throttle body? Will that be compatible with the ecu? Will we ba able to retain cruise control? Will the throttle cable be long enough? And what about the egr stuff attached to the manifold?

Just trying to think things through here before I go and start buying parts.
