4age rod in a 4ac??

[Shakotan_Aaron]

i have googled this and searched the forum, cant seem to find what im after.

what i want to know is will 4age rods fit into a 4ac? if so are there any modifications that need to be done to them? what version of 4age would be best to get them from?

please use relitivly plain laungage

thanks

easy, dont bother, you will not be getting that much to warrant it in a 4AC.
ive never even bothered looking at the 4ac crank but id imagine the 4ag will have a bigger main size and small end!

[Shakotan_Aaron]

im after somone who knows, that has done this before or has compared them. some people like to be diffrent. im thinking forced induction so stronger rods could help and i imagine 4ag rods would be much stronger. also they are cheap as second hand!

[LeeRoy]

Point being from Mick is that the gains received would be minimal and plus whatever you have to fork out for the rods you might as well save a little extra and just buy a 4a as eventually if u go the forced induction route youll spend heaps and then think why didn't i go a 4age instead. Plus eventually you will realise that you need a head that flows better and youll be after better pistons and so on. Buy a 4age or a ze, you wont look back. Plus the ze has better everything especially since your going forced induction. It will result in less stuff you need to buy.

Well a turbo 4A-C will definatly be different. Different and crap. The 4A-C sucks. It's not even cross flow, let alone DOHC or fuel injected! Go a 4A-GE or 4A-GZE. Much much better option.

To turbo the 4A-C you'll basicaly want a 4A-GZE bottom end. Crank, rods, pistons, and all the goodies that go with it. You can either do that, or just buy a 4A-GZE bottom end and put your 4A-C head on it. This would, however, be taking a perfectly good 4A-GZE and ruining it. If you go down this path, you'll end up with something that makes about the same power as a bigport 4A-GE, is laggy and peaky, with shamefull fuel economy. That's if you can even get it to work properly with the carby.

Keep in mind aswell, the 4A-GE is showing it's age now. The 20 valves are quite good, but the old bigports only make 88kw or so. That's not much power. A 4A-GE is a 'fun' engine, not a powerhouse. And you're going to be spending a whole bunch of cash on making your engine almost as good as a stock 4A-GE. Hell I even consider my B18C2 a 'fun' engine. It's not that powerfull to me, and it makes 125kw, which is even more than a standard 4A-GZE.

By all means, be different. But I don't think you understand how shit a 4A-C is and how much of a waste of time it's gonna be.

Here's different. Take your AE71, and put a 2ZZ-GE in it. Or figure out how to get a B16 into it, then turbo charge the sucker! That's different!

P.S. You say in your sig that you have a 4A-C for it, but you want a tacho to see what you're giving the 4K? Which engine do you want in there? The K series or the A series?

...and even then to get all these parts you would be better off buying a complete motor...in which case why wouldnt you use it???

p.s Nim, go to bed it's 5am

Yeah that's what I was implying.

NEVAHH!!!! Wait yeah I probably should.

Why the hell are you still up?

[LeeRoy]

I just got home from work and i thought i'd see whats happening on toymods while im having a beer. I prob should go to bed also cause i might go to the dyno day if i can get up at 10.

Doesn't seem too bad for what it is.

i have read though that thred.

guys dont hijack my thred!!!

i think you are missing my point i want to know if 4age rods will bolt into a 4ac?? dont you think i have been told a thousand times that 4acs are shit!! and to go 4age, but yet i persist. i have thought of the turbo option and i thought if i put some cheap stronger rods in i wouldnt go though the 4acs as quick and there is no way i am putting gze internals in, im not that stupid (yes i am). im still in the planning stages and looking if it is feasable to go this route or not. i know what i will end up with, basicly the equivilant of a standard big port. i am a student and a broke one at that so i cant afford a 4age like all you full time working mofos....

and i have a slope front ke70 (ae71 looking) i signed up when i was looking for an ae71 but ended up buying a ke70 because it was cheapish and i need to buy something. it has a 4k at the moment im tracking down a t-50 and conversin parts.

so if someone can tell me for shoure weather or not i can buy some strong rods and chuck them in please let me know!!!!

[kingmick]

thought i already did

[Shakotan_Aaron]

that was an imagine, not a definate yes/no

if anyone one has a a rod of each or knows a joe accross the road that would have one i would really aprecate it.

[LeeRoy]

Kudos for somthing different but you'll end up with a motor that will shit itself. Your gunna spend heaps on getting custom manifolds cause the ge ones won't bolt to the carby head, then you'll still have shit pistons, and a shit crank along with all the other things that are missing that will help ensure longevity. Although your thinking this is the more feasible route you are clearly misguided. You will also need someone to tune the car so it will even run.

You could go out and buy a 4agze with lsd box on Central Vic Auto Parts for $650. And this motor WILL run on its standard computer and make decent power. Bite the bullet and wait till you've got some money. You won't regret it.

completely stock unopened 220,000km block

Notice that that dude didn't bother opening the block up? Opening the block is expensive when it comes to putting it back together. For a 4A-C, there isn't any point, as the price of doing so will start to get close to 4A-GZE territory. I'm sure you could pick one up for well under $1000. I've seen fully re-built ones for ~$1200.

His 4A-C turbo will likely not last that long either. If you wanna make one that will last, you'll need low comp pistons, which means you may aswell get 4A-GZE pistons and rods, which means you may aswell get a 4A-GZE block that you don't have to open up... while you're at it you may aswell get the whole engine. It'll last way longer, be cheaper in the end, and provide you with more power.

And 90rwkw 'un dynoed' sounds to me like it's really about 70rwkw. Which is actualy still more than I would expect from a turbo 4A-C.

Anyway, in the end, going fast costs money. If you don't have money, I suggest you stick to something a bit slower. It'll cost less in blown up engines and petrol. Nothing worse than looking at your car and thinking "I can't drive you 'cuz I can't afford the petrol."

And we're not hijacking your thread. Your question is will 4A-GE rods fit in a 4A-C. The answer is: Don't bother.

[LeeRoy]

I'll give you some info you might wanna read up on... google is a wonderful thing.

Turbo 4ac discussion
Flywheel differences and clutch combos
More specs
Some z/te info

My spoon is tired now, he's going to bed

And as Nim said you'll need to pull the motor apart and then you'll end up spending heaps on gaskets.
