Engine Silvertop Question?

for 98+ the 2zz would be a easier swap.

can a v8 fit in the 8th gen?

No way... a V8 would be around 4-5 liters. Thats like 3-4 times bigger than the 1ZZFE.

Silvertop Question?

Would it be totally rediculous to swap out the 1ZZ-FE for a Silvertop???

Yeah.
Get the blacktop, it's better.

but nevertheless there's going to be more power, right?

The time and money you will spending changing out the engine, and messing around with it, I would just say its less of a hassle to buy a better used car with a stronger engine.

FTW.

Get a subie!

If you're going the swap yourself, it is a good swap. If not and you don't plan to keep your car for the next maybe 10years, your better off selling your car and buying "faster" in stock trim car.

i dunno some people like the raw power for drag racing , me myself is a track guy . drag racing is boring to me . but youre right , that would be unsteerable in the curves , but would be a good sleeper.

unless you want to turbo in the long run , the silver has a better engine managment system easier for turbo aps versus the black top , but for all motor , hell yah , the black top w./ the 6 speed and the lsd.

maf vs. map

it could w/ a lot of customization , this guy put a northstar v8 4.o in an mr2 , the mr2 and corolla pretty much share engine mount platforms pre 98 . the only difference in after 98 , is the shape of the motor mount , which can be changed by turning a few bolts.

yes , at least 50-60 more hp .

question

ive herd gud n bad things bouth the 20v which forces me 2 ask whats betta a 16v or a 20v?

Well tell us about the good and bad things you've heard. We can confirm whether or not it's true or not. I personally haven't heard any bad things about either motor. The Formula Atlantic 4AG is a full race motor making 240 hp and revs to 13k. It's a 16v. I doubt you can get that thing smog ready for the street. The 20v makes impressive power as well on a street level which I think is the more logical choice.

btw Not trying to pick on you, but typing like you're text messaging makes it hard for people to understand you and gives other people a bad impression of you. Please type normally please.

Don't get fooled by TOYOTA here.... the numbers they are advertising are way higher than real life... the silver top is pushing something close to 145 to 150 bhp, not 165 like toyota advertize. The blacktop only pushes 155 bhp at the most, not even close to the 170. In other word, for the amount of work put into it, tune your 1zz, which has the potential to make 140hp in stock form, so would take minor upgrade in air flow and fuel map to match a real good stock blacktop. In term of potential, the most N/A hp I have ever seen from a 20 valve is about 215, which would be hard for the 1zz to get to, but this is tunned to the max, with a shit load of money inversted.

I have looked at this swap before and concluded that it is a complete waiste of money, if you are going to go trough a complete swap, there are better engines out there. but if you like the challenge of a swap or if you like your car to be different, go for it man. Your car, your money... your choice!

And by the way I have a LOT of experince with the 4age big port (16V) and in term of ultimate N/A power, the 16 valve will out flow the 20 valve in real life, even if flow bench numbers (constant flow numbers) are telling the oposite. Believe me.

are those numbers wheel or crank hp?

swapping a blacktop or silvertop is a real project but for me i rather do 2zz just because of the vvtl-i(the lift).

Those are crank hp. That`s why I`m comparing those numbers to crank hp numbers for the 1ZZ hell 1G for the engine plus the time and other bits and pieces missing for 10 crank hp.... get engine management for a 1ZZ and you will be within range of the 20 valves for a lot less trouble. just my 2 cents.

here is the link too a REAL black top crank dyno pull

For your info, I`m trying to get the most outta the 1ZZ with only head flow work, intake, cams and fuel management. I`m expecting to burn 1000 to 1500$ into this, since I`m custom fabricating almost everything, and acording to dyno sim, it could get me anywhere between 170 to 210 crank hp... which is a lot more than a 4age for the same amout of money.

here is a like to the thread that explains it all

1zz doesnt have nearly the same amount of aftermarket support as the 4age does, you dont even have to be a genius at cars to know that. i dont think you should swap unless your engine blows out might as well keep the orginal engine as long as you can than swap it out when it breaks

Aftermarket support doesn't mean anything more than "their is not enough money to be made by big companies there". If you have the skills and know how, nothing can stop you from doing anything outta any block

I have turned a CA20E, 2.0L I4 iron block sohc 8 valves 8 plugs from nissan into a real beast without any aftermarket support, nearly all of the parts and peices were taken from the local junkyard and adapted or rebuild by me. I haven't put a grand into this project and the thing was spinning the rear tires at 100 kph in 3rd on the highway, BIG TIME.

Plus aftermarket support on the 20 valve is quite limited compared to the 16 V. Apart from the fact that you have to import all your gasket, piston and crap from over seas just to be able to rebuild it. Too much trouble for what it gives back, once again just my 2 cents.

Tom

ive heard that there is a lot more you can do to a 16 valve than a to valve. also when you 7age it it is much harder and more expencive to do to a 20 valve
