Max a 16v 4AGE can be tuned to?

[heshan]

Hey guys,

I went around the main areas in Colombo to find a 4AGE 20V but ended up just getting sun burnt. So I'm just wondering..

How much can a 16V 4AGE be tuned to give out. As mine is a JDM 16V its supposed to give out around 130hp stock.

So what's the max power this engine can give when mod'ed?
how much?
what parts?

thanks,
Heshan.

Depends on what way you would be going and what cash you're willing to spend on it.
350 - 400 HP is the highest I've heard of... But then you're talking about a heavily modified 4AGE with a large turbo and low compression pistons...
Keeping it NA you should be able to get till 160HP without too much trouble and money and anything above 200HP will cost you a small fortune.
Better read the Billzilla guide to get the idea:

Easy,
how much money you got?
Anything is possible with $$$

[heshan]

exact reason why I put up the topic. Need to figure out how much of money is needed to mod it to maybe 180hp from the stock engine.

I read the entire article Banpei posted earlier and its quite unbelievable that a stock 16V can be mod'd to have more HP than a blacktop. But still I'm trying to figure out how much and how. I'm trying to run away from engine issues I'm having with my 16V hence the reason for me to search for a BT as its a newer model and easier to find parts for it than the 16v.

20v complete head with 7a bottom end with silvertop rods & a bit of effort,
or 20v with overbored block & dirty datsun ca18 83mm pistons. It all depends on what you can do or you local engine shops & parts avilability.

well I can tell you now that the mechanics here in SL will not have the experience to do that so I'm going to forget about that. but I think I might get the BT as it'll give me a better start of around 150hp with the 95 octane we have here.

So according to the Banpei's article putting new Cams will make a huge difference in making the power increase from around 150 to even 200. So what's the best of cam's around for a good price?

any recommendations through experience?

Both 20V and 16v head have pretty much the same max hp level.
Older 16v have weaker low end, but if you switch to 4AGZE internals 16v can be as much as powerful.

I think it costs the same to pump BT or 16V to 200HP.

What makes the biggest difference in my opinion is the fact that BT will offer 150+ hp both street and track drivable in stock form.

But, if you plan more, 16v or 20v... looks same to me. Maybe 16v is even better, much more people using it, more expirience, more parts..

[heshan]

hmm.. interesting.. But doesn't the ITB's and the VVT give some sort of additional tuning capability that the 16v TVIS versions don't have?

It seems quite illogical (not doubting what you guys are saying but just arguing with myself) that a engine with a base HP of around 150 can be tuned to 200hp at the same price as a older less technologically advanced engine such as the 16v.

[heshan]

also guys anyone out there with a spare 20v? for a dirt cheap price???

[Uzelac]

There are ITB's for 16V also, which you can easily put on bigport for the price difference between BT and 16V.
Also, VVTi is great but it makes better low and mid range response and not the high end power.
