I've been reading up on engine conversions for my SR5. From what I understand a eng code with a 4 on it, would be the same block as the original. So I found a site that sells engines, (http://www.tpautomotive.com if there are better places let me know). Now I got two choices, the 4AGE (20 valve) 4AGEZ (Super Charge) what do you guys recomend? If there are anyother engines that'll work let me know. Thanks guys.

nope, the 4afe in the sr5 and the 4age in all gts cars are totally different beasts.

to do the conversion u will need an entire front clip and suspension parts, brake parts and probably even engine mounts will have be changed.....it's a costly conversion...for the $, why dont u just go BUY a gts or turbo the 4afe?

The reason why I haven’t bought a gts or popped on a turbo is b/c it’s too easy. It’s cross my mind to buy a car with a fast engine all ready. (insurance is a bit of an issue too) Is the sr5 chassis that different that it would be loads of work, changing motor mounts isn’t that bad. I’m also going for aftermarket suspension, so that’s not a worry. Since I am new to Toyota (don’t want to drive civics anymore) I could be wrong but from what I understand is that those engines are practically drop and bolt in. I heard something about an 88 MR2 engine just being a straight forward conversion. To answer the money question, I'm hoping on the $3000 cdn range, but I can dig deeper. Wow that's alot of writing, thanks for wasting your time on this guys.

Hey yeah it didn't work.

Midnight GSI · 06-01-2003, 07:29 PM

I'll have to dig up that address.

As for the motor swap it's not that big of a deal.
It does drop right in.
All the mounts will work but new would be advised being the back mount is a complete pain in the ass to get too.
The mr2 motor will work but you will have to extend the wiring and spin the shift linkage 180 degrees at the tranny.
Much easier to just get the tranny/flywheel/starter out of GTS or GSI prizm and you will be good to go.(for the largeport or small port 16V)
Some of the GZE trannys came w/ LSD.
The 6 speed from the black top is said to be weak compared to the 5 speed (C52).
Other than that the next biatch is the wiring from the ECU to the dashboard.
On thing that got me was trying to use the oil press. sensor from the GTS w/ the dummy light in the BSE/SR5 dashboard. It will not work.
You have to use the correct sensor for the dummy light to get the oil light on the dash board to go away.
I'll see if I can't get that address for you.
Hope this helps some.
C-YA!!

Midnight GSI · 06-01-2003, 07:33 PM

and you shouldn't have to change susp. parts.
Might just have to play around w/ differnet drive shafts till you find one that work.
(GZE/20V mostly)
C-YA!!

RedruM · 06-01-2003, 09:23 PM

the sr5 and gts front ends are completely different

it's not jus the shocks and springs, it's everything

the gts motor and all other 4age,gze,20vblack or silver sit the same (lower to the ground ) than the 4afe

jus for the suspension conversion you'll need $$$'s or jus get a front clip with everything attached

Midnight GSI · 06-02-2003, 08:51 AM

Hello
The only difference in the front Susp. is the control arms and the lack of front sway bar on the sr5 from the GTS.
The engine mounts go in the same location for the sr5 or gts.
The only real difference in the front brakes/ hub is the GTS's have a cooling duct and my BSE brakes didn't have.
The GZE/20V will have cooling ducts and a slightly larger Dia. rotor than the 16V's.

Why change the front Susp. if you don't have to. (Unless you want the swaybar and all)
I've had my swap for 2 Years and didn't have to change One susp. part.
(I have a largeport swap you know 4afe to 4age)

On a side note if you wanted the Susp.
I picked up an entire front and rear susp. off of a GSI(same as GTS) for 250.
Struts, Sprins, crossmember, control arms, hubs, rotors, driveshafts, brake lines, pressure valve, swaybars.
So it's not that much money.
On a side note you don't need the crossmember for the rear Just get the hubs and E Brake equlizer(its under the exhaust about 2 ft down from the CAT).

Plan on switching this out myself here in the next few weeks.

C-YA!!

I wouldn't worry too much about the suspension untill you get the engine in. If you are serious about creating a real Honda and Subaru Killer you will eventually be swapping out a lot of that stuff anyway. One thing at a time

Go with the SC motor and grab a FF tranny from another car (as mentioned above.) You can then change the SC pulleys and swap in larger injectors. After that mod the stock ECU is almost useless anyway and you will need to install your own www.sdsefi.com (my opinion) builds a system that is probably the least expensive and the easiest to install and program.

Note that putting the SC Engine in an AE92 still requires some extra work. The alternator has to be moved to a position underneath the engine (you have to make brackets) and some custom ducting of the fresh air intake will have to be done. Make sure you TRIPLE check the timing chain assembly and valve timing before you install the engine. Getting to that timing chain is a bitch once the engine is in. (I actually left a couple of covers off to make it easier for me in the future.)

whoever said putting in a turbo was easy?
may i ask u what type of fuel management u will be running if u are doing a turbo conversion and have a budget fo 3000 bucks?

and just "buying" a gts.....and thinking it will be a fast car is wrong. whoever said a gts was fast....i own a gts, and i definately do not think it's fast. my pos old civic with similar output will rip this gts to shreds in a drag race.

as for suspension, going aftermarket or not is besides the point. ahmed(xenon) has looked into this in detail and has discovered that the gts uses different suspension components. we're not just talking about springs and struts here....we're talkin control arms, possibly bolting points and subframe...

insurance wont make a large difference going from sr5 to gts, both cars will be cheap for insurance...

i think it's a wiser investment to spend 3000 on a gts, rather than modifying an sr5. nothing against the sr5...but it just doesnt make sense to me. u can have 2 cars...sr5=winter beater and gts=summer beater.

4agze is far from a drop in and go endeavor....the wiring harness will need to be extended...every single stupid wire will have to be extended. u will either have to relocate the top mount intercooler or get a hood scoop. then u will have to find urself an ecu to run it

please keep in mind that u are driving the sedan, not the coupe.

both are different cars....

as redrum said, the 4age sits differently in the gts when compared to the way the 4afe sits in the sr5. 4age sits lower...it's a much bigger engine.

Fuel managment system??? I'm starting off at $3000 in my pocket, I'll put in as much money as I need to. I drove 2 hours to see this SR5 and it was well taken care of with only 140,000 clicks. I don't feel like buying another car, I'm working with what I got. I never said the gts was fast I could go out and buy a 2004 Nissian SER Spec V or a nicer car. But I don't feel like paying the 500/mnth insurance.

Thanks there boroef
What is it that dictates the height of the engine?
Is it not the engine mounts?

The engine block is no bigger, Just the head is wider.

That bracket for the ALT, that would normaly be w/ the front clip of the S/C Ae92 right?

As for extending the wires:
You are refering to a AW11 GZE to the AE92 Right?

Just trying to understand where you are coming from and the dynamics of the coupe from the SDN.

C-YA!!
