sr20de or turbo ga16de?

[fishda]

hi guys,

newbie here... just want to ask kung ano mas ok engine swap my ga16de to a sr20de or turbo my ga16de? just want to have a little umph on the road... minsan po kasi sinabayan ako nang vtec sa hi way at feeling ko iiwanan nya ako kaya hindi ko na sya sinabayan... how much po kaya gagastusin ko kung sr20de swap gagawin ko compared to having a turbo? thanks for the inputs and God bless

[fishda]

my car po pala is a b14 series 3 sentra... may IHE na po sya and medyo nahihinaan pa rin po ako sa hatak nya... comparing it to my friend's SIR... hehe

An SiR versus a B14 Super Touring with an SR20DE with IHE... should be just about even. Versus a GA16DE with a turbo? Depends on the turbo boost. Anywhere between a confirmed kill and "what was that bug I just ran over?" A safe 7 psi of boost should get you about 160-180 hp.

But if you're the tinkering type, an SR20DE gives you more tuning options down the road... An SR20DE with a turbo is a monster of an engine.

And swapping to an SR20DE is cheaper than turboing the GA16DE (if you're turboing it properly, I mean).

I have done both.

I previously has a B13 with a GA16DE with turbocharger/intercooler upgrade. I also currently have a B14 with a SR20DE swapped to replace the GA16 motor. The SR20DE gives better overall performance and reliability (assuming you got a good condition motor and clean swap).

The SR20 would let you have the same overall power of a GA16DE turbo in factory stock setting. Minor mods including S-AFC and IHE would result in a boost of power from the 140hp stock to around 170hp to 180hp.

The B14 w/ SR20DE (stock) would slightly out-accelerate a Civic SiR simply because the engine has more torque. And given there are many mods readily available for the SR20, your options is only limited by your wallet and sanity. In the least, you can go nitrous or turbo to boost your power to 200hp.

If you insist on the GA16 w/ turbo route, you will need at least a stage 1 clutch upgrade to prevent the clutch from slipping or frying. You would also engage the gears carefully because I have damaged my B13's gearbox even when I still had it in all-motor setup. SR20 gearboxs are made stronger and some even come with LSDs which comes in handy when you are trying to corner at high speed.

As for cost, the GA16DE turbo would cost you more, almost twice more as compared to a SR20 swap (including the cost offset by selling the GA16 engine).

thanks so much for the replies sir... will consider swapping to an SR20de next year... will hold off with setting the setting up of the exterior... would you guys know how much all in all will i spend for an sr20de swap? and how much will i be able to sell my ga16de? would buyers consider it's very low mileage? i got it with just 34k mileage on it... now it has 37.5k... my cousin got sick and was not able to drive it for a very long time...

I don't know the current price but used to be a SR20 swap can be done under P65K. Make sure the engine mount that needs to be adjusted is done with proper alignment to the body.

As for the "trade-in" value of the GA16 motor, no idea.

[fishda]

time tighten up my budget hehehe....

btw... how many HP will a complete IHE setup for my ga16de give me? will it be enough to pass those other 1.6L sedans on the road?

Other sedans meaning non-SiR cars, yes but it will just do it barely.

My B13's GA16DE upgrade/setup:
-APEXi Super AFC (gen2 analog system)
-K&N cone intake
-Nodalo's 4-2-1 headers
-Nodalo's big body freeflow muffler (2.5inch internal tube diameter)
-2 inch exhaust piping
-"MSD" ignition controller
-"Torquemaster" sparkplugs
-"Hurricane" high tension wires
-"Clutchmaster" stage 1 clutch upgrade
-ignition advance

Based on my G-Tech Pro speed meter, my car would be doing around 125hp at the crank. 15hp over the stock 110hp isn't a lot especially on the amount of money spent. Not to mention my GA16DE fuel consumption is even more than a stock SR20DE would consume.

For the money spent, I could have had a SR20 engine swap done resulting in even more HP gained over the modified GA16.

for me less conversion iturbo mo ga16de mo tapos racing clutch ka at lighten pulleys lakas na nun,tipid sa gas na malakas,but if u want more power and torque mag sr20 ka, iba parin kc pag orig orig or bolt on bolt on ,think wisely comparing to ur gas comsumption dahil malakas sa gas ng bahagya ang sr20 pero malakas tlga,and then upgrade ur brakes d dapat mawala un >.<

Turbo charging a GA16de would require upgrading the fuel injectors from a SR20DE to handle the added fuel flow requirements. If not you will lean out every time you near the redline.

Racing clutch would just make it difficult to drive in stop-go traffic. If you want to upgrade, choose a stage 1 clutch upgrade kit although you might have to order one from abroad like from "clutchmasters". You might also want to consider that the SR20DE gearbox is more durable than the one that came with the GA16DE as I have damaged a gear in the past in my old B13 sentra with Ga16de with full bolt-on upgrades.

Lighten pulleys? or underdrive pulleys? Lightened pulleys won't really do much. Underdrive pulleys might compromise the flow of the water pump and result in overheating. The turbo would increase the engine's heat so even with stock pulleys, an extended run with the turbo might result in seeing an sudden spike in the water temperature.

Fuel consumption of a GA16DE turbo vs a stock SR20DE is about the same. GA16DE with bolt-ons can guzzle gasoline MORE than a stock SR20DE for less HP.

^^^Take it from this guy... he's done both...

[Slidingmy240sx]

the SR20DE engine is a better all-around engine, where you're gettin a good amount of power, torque, good delivery, reliability and fuel consumption over a turbo GA16DE. I mean, i do have an SR20DET in my S13 in the States...and when i stay outta boost, i do get really good gas milage.

So are you in the USA now?

gh and niky,

planning to mod my exalta. engine still on stock. IHE will be done at SMT probably early 2009. (if i wont be able to get a pickup by then yet)

any suggestions on modding it? after a full IHE what can i do since it is a matic transmission.

Vanette Grand Coach - has SR20 Engine as stock

dre mas maganda sr20 ksi yung ga16de pag nka turbo iiksi ang buhay ^_^ lalu na kung hahabol ka sa SIR at sabi nga nila mas mahal magpaturbo pra kang bumili ng makina d pa ksama pipe-ing at tune-ing dun at gauges

kuha ka nlang ng SR20DET+Prog BOX+Boost Control.... nakakalaway huhuhuhuhu mag se-setup ka tlga d lang just for the thrill chasing SIR

pag nagawa mo ito aabangan kita sa macapagal parati ^_^

yan lang magandang shocks at goma good to race kna mpa track or street hahaha

or..... benta mo nlang yan tpos mag honda ka bwahahaha

No need for a SR20DET if all you are going after are Civic SiR. A stock SR20DE will be good enough to beat them.

i like this... how about for my stopping power? will the 4 stock disc brakes be enough? i wish to say ba bye to those mean sir's... hehe...

You can use the stock discs but I strongly suggest you upgrade all the pads with more aggressive aftermarket brake pads.

It's also possible to find big disc upgrade kit that comes with a brake caliper bracket to move the stock caliper to it's new position.

Alternative is to use the compatible brakes from a bigger Nissan car. The ones I have on my car came from a Nissan Bluebird. Downside, it's a pain to find new pads when the current pads get worn down or heat damaged.

Remember the stock brakes were meant to handle 110hp. SR20DE stock is 140 to 145hp. My tuned SR20 probably does around 175hp (based on it's 152whp dyno run).
