To the OP speedygonzalez:

Despite the slight thread jack/ordeal that has happened here, I think the point everyone is trying to make is that based on your original post about being on a small budget the best way for you to get the power you want and still stay na would be a 20v swap. You mentioned you have mechanic in your family I am sure they could help you get the swap completed. (it should net you somewhere around 150 in stock form which is ballpark about 30-40 more hp then a stock 16v so you will notice the difference. The best way to get to 200 hp would be with a turboed or supercharged engine. You can find 4agze's decently priced if you look around or just ask your family to help you buildup one from scratch. i know 2restomod had a spare 4agze bottom end a month or so ago. not sure what he would sell it for?

But there is plenty of information and knowledge here on this forum that if you decided to swap with the help of your family and this board the task could be easily accomplished.

EDIT:

I would also like to add in case you aren't aware that both the 20v and the 4agze (supercharged 16v) are direct bolt ins there will be wiring modifications and a few other things to be done with both swaps. However the engines themselves use the same mounting points are the 16v in you car now. so no modifying of the chassis or the motor mount locations isn't needed. So its basically just the finer details you need to worry about. Oh and if you go with a 20v I recommend mr220v's wiring harness not sure what it costs but its a plug and play replacement for the one in your car now which will need to be replaced anyway and this save alot of time from what I hear and see posted on the engine swap section.


oh and before anyone comments on it lol, I am fully aware there are grammar/spelling errors in this posting :P but I am tired just got off work 20 hour shift. so i don't want to hear it :P

Here's the way I look at it.

Toyota already "built" a 16v 4age, and it's called the 20v 4age. Higher comp, upgraded electronics, higher lift and duration cams, itbs, vvt, and the 5th valve per cylinder. Some of these items would either be difficult or impossible to add into any 16v build, but toyota designed it, mass produced it, and now 16 years later it's available used for dirt cheap prices. Much cheaper than the custom/limited production/expensive aftermarket parts needed to build a remotely comparable 16v motor.

And it gets good fuel economy.

3SGE>4AGE for anything over 150HP

think about it, a 3rd gen 3SGE makes a hell of a lot more power stock then what you can dump into a 4AGE. 'nuff said.

yes i do know better then the "main" car makers i was trained in my mechanics by a toyota engi. and a bmw/mazda mech.. factory cars are made to last with room for improvement you gota learn to work in thouse boundries and whats too much and whats not enough for you. simple minded folks that think only factorys can make a reliable motor get out side this 20v box. my 4a-ge had 234000 befor i got it now its got like 89000 on the motor sence i did my work so if you combind thouse to on the stock block that over 300000 miles on the stock block stock trannie. and trust me i beat up my cars nothing can survive me for long nothing but that datsun and this mr2 i cant break its because i work in thouse limatations and stomp 20vs around here on track on street its all on what you do and what your looking for in a motor 20v arnt that great and trust me when i got this mk1 i was planning a 20v swap till i drove my friends 20v and it wasnt any better and he had 4 carb setup and some other stuff done to it it wasnt that greati have more revs better throttel responce and its lighter

[TomsMR2]

the FA motors were about 15 THOUSAND dollars and lasted a few days.. and you're saying you made 10 more hp and went 200K on it? get your head out of the clouds.

[lsgheero]

hires the stig to get a formula 4age equipped car and race his ass. Anyway im done with this thread as it is going nowhere I hope the OP is able to come a decision based on the comments on this thread.

Im going to bed now you guys have fun I will see you in many hours lol

[enzospriggs]

im saying i got 165 hp and can retune it to 200 in 15min and it has 89000 miles on my building of the motor and it started with over 200000 miles on it. i build and know how to build motors that last and this kid/guys want help builing a 4a-ge 16v people he doesnt want to do a swap as long as you dont go to crazy with it its better then a 20v anyday

I think you mean the STIG.

Besides, no one knows who the current stig is. The one in black, I forget who he was, I'd have to look it up. But he revealed himself in his book. The current (white) stig, no one knwos who he is, unless of course you're Jeremy Clarkson, James May or Richard Hammond. I wouldn't be surprised if you said you were Jeremy Clarkson, given your achievements in life.

Regardless, there is no "Fastest F1 team" McLaren Mercedes & Scuderia Ferrari are the top two arguably. BMW Sauber has been doing wonderful this year as well. Hopefully they'll continue make the sport that much more competitive.

have you considered a smaller turbo?

yes turbos have lag (already mentioned), but a properly sized turbo would get you just as much if not MORE power than from a supercharger, and it would lag quite a bit less

ive driven several 240SXs powered by GT28RS (not the stock S15 turbo) and they spooled at under 2000 rpm. not really my thing (i preffered the T3/T4 hybrids on mine), but many people absolutely adore them.

granted your thinking of a 1.6 liter vs a 2.0 (or 2.4 in some cases), but it shouldn't be too hard to find a properly sized turbo with minimal lag and good power gains without spending the money to do a complete rebuild of an NA machine.






and if all else fails, you could swap in a Formula Atlantic 4AGE. its still 16 valve

[mr220v]

What's wrong with being made to last? Most guys who build or swap a motor would want it to last more than 10000 miles. I know I don't want to change motors more than I change tires.

Also, what can you do to the 16v that can't be done to the 20v, or 3sge for that matter? You can't say that 20v upgrade parts aren't available.

to bad i know who the white new stig is hahahha do some research and watch some shows they give hints all day long and its only been 1 guy besides a cupple shows where his brother or cuz showed up whiles there outa counrty and yes thx i did mean stig see some time keys dont type when i hit them and i dont wanna go back and fix it

[Ku-sama]

it's funny how he is saying you can P&P a 16V head to make it flow better then a 20V head.... WHEN YOU CAN DO THE SAME DAMN THING TO A 20V!
