4g93p Sohc Vs Dohc

[mrashidi]

Hi all,
:rolleyes: I'm new here, try to find any talk about this issue but haven't see it. I plan to replace my current 4G93P SOHC auto to 4G93P DOHC SGTi enjin. will using back the auto tranny. From all experts out here, can you please share your experience or knowledge about this. is it worth to do it.?? Can you please advise me.
Thanks. :blink:

Err... u going to maintain auto woh... worth it meh? I think u probably won't feel as much as manual change from sohc to dohc.

The DOHC engine would be better at higher revs. But can your auto tranny take it?

 

[mrashidi]

:rolleyes:
yeah, now i got it. thanks to you 2...alvin, prozac... so for now, just maintain the original condition.. hehehehhe... thanks guys.. actually i'm looking for smooth engine during accelerate.. that is why i'm asking whether 4G93P DOHC is the right choice.. :)

If yours wasn't a 1.8, but a 1.6 instead... then I'd ask u to put in a V6 engine (mitsu's 6A10... 1.6 V6)... coz' V6 engine's ride is damn smooth. But then no point downgrading your displacement lar... coz' u might end up with less power anyway.

Hi, mines a Satria 95' fitted with a 4G93 DOHC. Fits like a glove........Power is OK though. Not much headache. Its a good choice...i think. But for the price of the half-cut you can most probably get a VR4 but much more reliable.....anyhow its up to you to decide if its power or reliabilty that you want. Cheers! :)

there's no difference in reliability of the 4G93 and 4G63T if you're planning to get halfcuts, they are both used and more than 10 years old. Either way you're encouraged to do a proper overhaul for any engine conversion.

I was previously using an auto 1.8 sohc and I've also tried driving an auto 1.8 dohc on another proton. Can't tell the difference. They're both underpowered in terms of pickup and high on fuel consumption. The auto changes gears at 3000-4000+ rpm so any power difference is hard to differenciate.

To really have a difference in power you can consider either a 4G93T or 4G63T. Since you already have a 4G93P, it would be easier to convert to the 93T with minimal changes ie. ecu rechip, 4G93T engine kosong, intercooler & piping. You don't need to re-wire the engine.

V6 is really a good engine but bare in mind the maintainance will be damm higheven the service charges when u wanna service your car the labour will be higher then your lubricant :D if really wanna go v6 use the mivec 2.0 v6 remember ETERNA halfcut not FTO. that 1 with auto also damm powerful

 

[mrashidi]

hi vertical,
how much roughly the Mivec V6 & 4G93T auto cost ya..??? hmm.. thinking either V6 or 4G93T... (still consider) hehehhehee.... prefer smooth & good acceleration engine with auto transmission...
