THE SR20 vs 4AGE ARGUMENT/discusion FOR THE LOVERS AND HATERS

[KE70GT]

3sge ftw cause it has it's cams in the right place over the valves, none of this rocker arm bs that the sr has and even though it's cast iron it's still lighter then an sr

i don't think you should be comparing a 4a against an sr cause they were built at different times and they have different capacity’s 4a should be compared to a Nissan 1.6 that was built in the 80s

[groupa4agte]

i hate this debate on the 4A vs SR
i dont think they should be compared as one s a 2L and a newer design
if only the 4age was a 2L and was designed with coilpacks etc and built for a turbo
Now that would be a very interesting comparison

[R&D Mechanical]

Eddie, can you please post up your full spec list of your engine setups please?

ie 4agte: list mods SR20: list mods.


Would like to see the differances, how MUCH boost? etc

I think running way to much boost is the case

cheers

Beally, gotta remember that the 3S weighs a fair bit more than the alloy block SR no?

[Chaos Theory]

i have read on toymods that despite sr's alloy block the 3s are actually lighter, dont know if its true though.

[driftke70]

not really hey, they use iron sure, but less of it. It comes from the factory with a ballanced bottom end and forged pistons in the 205. When you take into account everything from both conversion i rekon youd be lucky to find 10 kg difference. I pulled a fuckload of weight out of originial dump pipes and car/engine mounts etc, Not much left when all you run off the belt is an alternator.

where does the beams 3s stand in all this
i decided the beams over the sr

[ke70dave]

its not really a fair comparison...

one is turbo 2L from factory and marketed as a performance engine. which have sold millions of.

the other happends to be the top of the line engine in the toyota corolla, a cheap car that they have sold millions of. andit sonly 1.6L and people happen to bolt turbo engines onto them.

a better comparison would be:

3sgte vs sr20det or
4age vs bda cosworth (ohh mumma id love a bda)
sr20det vs fj20det or
sr20det vs 13bt or
4age vs honda's equivilent
sr20det vs 4g63? (evo engine)

4agte vs ca18det is prolly the closest comparison, but even then one is factory, and the other isn't. and as soon as you start doing something that isnt factory then unless you do everything perfectly then you are going to introduce some unreliabilities.

i would be inclined to put a sr20 in my car if i ever went turbo, purely for the fact that its a factory turbo engine, but then again if i had the cash id prolly just buy an s14 or something. least you get a comfy car that is quite nice, as opposed to a 25yr old hacked together thing haha

[Hen may possibly be a nut]

My experiences:
Got a 4AGZE from a wrecker, bolted it in (think I changed oil, filter and plugs), upped the boost and drove every single drift event in Victoria, plus some interstate ones for about 3 years, plus a bunch of daily driving. Ran on whatever oil I found, and regularly was off the dipstick at the end of a night. Eventually snapped a crankshaft (bad luck? too tight SC belt? who knows).

In that time I saw countless stock, modified and fully built SR20s blow up in friends drift cars.

Sure it comes down to a bunch of factors, but I think you can see why I think 4As are less likely to die.

I say "each to ones own.". any motor that does the job required of it and does it within the required budget is the one you want. my only 4a was a bog stock 4ac that got the absolute shit thrashed out of it doing crazy revs, very little [if any] services, and it took this abuse for about 3 years of my apprenticeship. It never broke down just kept getting slightly slower. it was still running when i pulled it out. On that experience i wouldn't hesitate on a stock 4ag for daily duties. BUT for track.. [and not having driven a 4ag or 4agte] my ke with sr i got from simonke is a absolute machine. Awsome motor that just works bloody well. I was never a fan of the sound of an sr [hate them with a screamer] but this one has really grown on me. Still, quads and a lot of rpm will always sound the ducks nuts. One day i'd like a 4agte as i got hooked on ke70s years ago when zoom magazine did a conversion issue and there was a matt black ke on the cover from new zealand with a ze bottom end and 20 valve head making just shy of 300atwkw [wasn't a daily though].
plus it is a bit harsh facing a 1.6 against 2.0. reminds me of a battle i saw recently with a 1.6na vs sr2.4det off its nuts but both engines got the job done to make it to the battle. was a shame about the outcome of it though. lol
