[Special_Edy]

Ok let me first say that zfjohnson bought the car not running from the PO and the damage wasnt discovered till this video.

Enjoy

Right now he is debating his options- replace the shortblock, swap in a 4age, or upgrade to GT driveline and seap in an S series engine

thats fantastic!!! id stay away from the $a, IMO its just not worth it. if you were going to spend the money on a 5S, then why not just drop in a 1MZ? I know, im a V6 fan boy now

[zfjohnson07]

well im not too good with engines, so my intent was to put a 7afe with low mileage in it and get good gas mileage, but if i could find a 3sgte and get someone to help me install it i might do that, but i need yalls opinions like he said.

<<edit>>
i found a 3sge for 900 jdm, should i get that?

well, if you have two celicas it basically comes down to which one you want to be your daily driver, and which one will be the project car. I say turn the one with the busted 7a into a project car since it needs a new motor anyway.

So it knocked a little?

My current theory is that maybe the PO dropped it into too low a gear and the rods came apart. Or a rod broke and the shrapnel shattered a second rod. It looks like they broke along the length of it. Good $hit though, a missing rod, a second rod in 5000 pieces in the oil pan. 3 holes through the side of the block and one hole through the cast aluminum upper oil pan big enough to fit your hand through

I say find a 92-93 es300 or v6 camry thats 5speed thats wrecked in rear/side
pull the 3vz/e153 buy gt4 mounts an smaays pass side mount gt4 shifter cables an build a set of custom axles like use in 3s/e153 swaps an call it aday

Oh an youll need to get the harness done an get a gt cross member

You could probably talk to stephen_lee there in texas for more details he done this same swap in a st

[Bitter]

3VZ sucks, such a boat anchor. 1MZ with VVT-i. Weighs the same as a 5S (maybe a little less), less than a 3S-GTE, and instant 200hp/200lbft on 87 octane. Maybe use a 3MZ with a 1MZ ported intake manifold and a bored throttle body so you can run a 1MZ ecm with a piggy back and throttle cable? Ok, now that's just getting fancy. You don't need a 250hp 6G Celica.

3vz has a little more room to grow
It has a stronger block an better inturnals compared to the 1mz
so turbo is a good option on 3vz. Plus its alot cheaper/easier swap

These are all valid points, but it's old tech. It's like the 5S-FE of V6's.

[zfjohnson07]

Well I kinda want a 7afe but I found a 3sge from jdm import for the same price so I'm still debating on what I should do

[kurt95gt]

Id just stick with the 7a since its easier to get parts for

It might be old tech but after dealing with wih the 1mz's new tech id much rather work on the old tech

Imo tuning a carb an turning a distributor to wake up a motor is alot easier that wiring in a piggyback an dialing it in lol
Been work on the ol v8 all weekend forgot how much fun they are lol

[Bitter]

Sure, if you like 45HP/Liter....

[Smaay]

im gonna have to disagree with ya Kurt, a 1MZ is a much better platform. even for boost. just because the 3VZ is an iron block does not make it that much better. the 1MZ has a fairly thick steel sleeve in the cylinder that i have no doubt will support 400 HP. all you need is a good piston.

[Special_Edy]

I vote 7AFE since this is his first experience with a major teardown and rebuild.

A nice used shortblock, gasket set, headbolt set, and of course the head decked and Magnafluxed. Maybe $500-800 total

[kurt95gt]

Im not saying the 1mz isnt a better motor than a 3vz but from what ive seen/read the 3vz is better for turbo builds an is alittle bit more of a budget friendly option thats all.

I was not aware the 1mz had. Steel sleeves. That would help it hold desent boost numbers but id still feel better with the stronger block.

[kurt95gt]

????
Trying to say v8's suck?
I like my 1mz celica but it couldnt outrun run my nova in a quarter mile
An if you put both motors on the same budget the 350 in my nova will build more power probably every time.
For me theres no real comparison between the 2 but thats just me
I started wrenching on old chevys an fords an bought my first import for the mpgs. Not for the power

[zfjohnson07]

ha ha, personally i would prefer a 4 cyliner with about 250 hp thats if i got the 3sgt3, then you figure the weight on the car compared to a guy with a v6 or a v8 mustang, camaro, trans am, any car, id take the 3sgte any day

[Smaay]

this is what the cylinders look like

[Box]

No replacement for displacement.

Any who, being it's a ST I'd just get another 7A-FE for it and call it a day. I have a ST, and once I want to do a V6 swap I'm just going to go out and find a GT with a blown motor. Probably would be cheaper, and save my health a little more.

[Special_Edy]

Aluminum is superior to steel for building engines because

it is stiffer, transfers heat better and it weighs half as much as steel.

All aluminum engines, at least 99.9% of them, have steel sleeves or jugs in them because aluminum doesnt stand up to piston rings scraping back and forth like steel does.

I would take aluminum over steel anyday, it just costs alot more. At the scrap yard steel is $25 a ton while aluminum is 30¢ a pound. Do the math

[Bitter]

2ZZ swap with 9:1 pistons and boost. DONE!
