Replacement for CA20 engine

[CoolSwitch]

Ano po pwede replacement na makina sa CA20 (Nissan Maxima). Dadalhin ko kasi sa mekaniko this week, and kapag sinabi na overhaul, baka magpalit na lang ako makina.

Ano compatible replacement pwede?

thanks

An SR20 will fit just fine. Wiring will be completely custom, and you'll need to change your instrument cluster, but it's a common swap for front-wheel drive Nissans.

Prepare for sticker shock. Expect to spend between 50-60k pesos.

sr18 or ga16de pwede na..

I would think the GA16DE and GA16DNE is too small but I checked the specs and it's a close match to the CA20's output (HP and torque). Downside, the complex EFI wiring. Upside, complete running engines are cheap and plentiful.

Alternative might be the GA16S or GA16DS (carb versions). Not as powerful (only 94 to 95 HP) but since it's carb, less complex to install. Downside, it's still a carb engine and if there is a problem with the carb itself, it might be expensive to fix.

If you plan to keep the Maxima, I would suggest the SR20DE swap as well. Just have it planned out correctly and patiently. It will be a bit pricey (as Niky mentioned) but the end result would be a more powerful car (from the original 105hp to 140hp) with a more modern EFI system and hopefully better fuel economy.

How much ang running price for the above-mentioned engines...

And how much do you think an overhaul usually costs?

Is it still worth it to have the engine overhauled?

[alwayz_yummy]

kung may andats ka.. SR20VE or VET hehehe...

SR16VE N1 ok din..

as for the engines mentioned above-- prepare a maximum of 100T for a complete swap.

ang prob sa CA20s ng maxima natin ay ung availability ng parts, maoverhaul mo man yan, pero it depends na din sa gagawa.

[boy_tino]

SR20 from altima puedeng puede na yan

SR20DE would be around P50K to P60K for the complete swap.

SR18DE should be around a little less that amount. Downside, locally it's not as common as the SR20.

The GA16 series engines would be significantly less. Purchase price would be 10k to maybe 20K for a complete engine (depending on the type of GA16 engine). Add labor of around 10k to 15k. If you are getting the EFI version, make sure you get the complete "set" which includes the ECU and uncut wiring harness. The carb version of the GA16 engines were used in the locally sold Nissan AD Resort. You should also prepare a budget of around P10k for other stuff that might or might not need to be replaced or done, like moving engine mounts, replacing certain electronic stuff like sensors which might have been damaged, replacement gauges if the stock gauges (mainly the tach) aren't compatible, etc.

A full overhaul can cost around P30K to P80K for labor and parts. Some parts can be repaired or refinished but others would need replacement. For the CA20, getting those parts might be a little difficult.

I hate the AD Resort version of the engine... because I have one. The GA13s in the Sentra FE have a better carburetor and rev more freely.

If you're upgrading to a GA16... might as well get the fuel injected one. Be aware that the Exalta series (around 99-01) GA16s have VTC, also... which could be good or bad, depending on whether you want a little more power or a little less complication.

The SR20DE is the absolute best bang for buck swap. Even better, the Altima SR20DE will have drive-axles that are the proper length. Sentra driveaxles on the GA16 might be a tad short for the Maxima's width.

Only thing extra over the GA16 swap you'd likely need is a better fuel pump.

True but the thread-starter is comparing prices/costs of either doing an engine swap or overhauling the existing engine. So performance is not the priority but cost in the short and long run.

Which you think is the better GA16 version for this? .... the GA16DE or the GA16DNE? I would be leaning towards the DNE because of less problems like the idle problem associated with the GA16DE in the B13s.

Well... it depends... is waiting months for parts that may never come equivalent to the cost of swapping?

But still... the problem of drive-axle length will decide the thing. If there is a problem, then the cost of a GA16 swap will go up commesurately, and the extra cost of the SR20 swap, in comparison, will not be as big.

The later, the better, I guess. :D

So the question boils down to... will the GA16 fit the tranny spline and bell housing of the CA20 tranny? If yes, then that solves the axel problem.

I would not recommend a GA series engine swap with your Maxima. Although your Maxima is a 3rd Gen Stanza in the International market, the chasis is a real Maxima. So it's heavy. GA engines just won't do the job. Either have the CA20 overhauled (like what I did with my Maxima... a keeper!) or replace it with the SR series engine.

Actually if you compare engine specs of the GA16DE vs the CA20, you'll see they are a close match in hp and torque.

Installing a SR20DE engine would be more expensive.

I still won't recommend a GA16DE swap with the CA20. Why settle for an engine with the same power while you can have a SR20DE which is more powerful? Yun nga lang, mas mahal pero mas hataw.

From my experience, the CA20 still has the performance edge over the GA16DE. Paperwise, halos pareho lang talaga ang ang specs nila.

Why settle? ... maybe if cost is the primary concern of the TS. The cost between overhauling the existing motor and doing an engine swap.

Not all engine swaps are about more power. Some are more into the practical side of having a more modern engine with the same performance as the original motor.

The thread is about either overhauling the old CA20 or doing an engine swap. Performance difference between the CA20 and GA16 is not the topic.

Thanks for the inputs...

Primary Intention is just to make it run in good condition, travelling with less worries if none is close to impossible...

Thus, overhaul or swap?

If no choice talaga, then probably going for a more powerful engine swap will be the last option

I received some inputs from someone, to go with the overhaul option, since I cannot be sure if an engine swap will automatically work for a long time...

still weighing my options though, of course money does play a big role

You can still decide later. Canvass all the parts you will be needing and have them estimate the cost of labor. And then add ten percent to the total because there will always be unforeseen stuff that will need to be replaced, etc.

After you got that amount, you can decide for certain which path you want to take.

BTW, engine swap will also need a change in registration.

thanks... sayang na-misplace ko yung quote ng FRENS (beside toyota alabang) they quoted along the 3+,+++ range, nandun pa naman yung parts na kailangan daw palitan...

will try to get other quotes from different mechs

The thread is about either overhauling the old CA20 or doing an engine swap. Performance difference between the CA20 and GA16 is not the topic.

But then again that is a MAYBE... common sense lang naman siguro na pag pera ang concern ay dun ka sa mas praktikal. Since we're broadening the options, we also have to consider performance.

At pag engine ang usapan, kahit na overhauling or swap pa yan, hindi mawawala ang power or performance sa topic. Alangan namang magpa-OH or swap ka w/o even considering the outcome. Would you settle for that?

Masyado ng mainit ang thread na ito. LOL! As to the TS, goodluck! You have a great ride. . . Have fun with your Maxima!
