G'day!

OK, just a quick question.

Can parts (head, pistons, etc.) from a 4G18 engine (Waja) be brought over to older engines, such as 4G15 & 4G13?
I was just wondering as parts between 4G15 & 4G13 are cross-compatible. Since a Waja's 4G18 is also within the 4G1X range, I just wanted to know if these parts can be mixed & matched.

The differences are obvious, but I'm asking nevertheless

Thanks guys!

dun think it's possible as cc might be different plus the engine design also different, there might be some small part which r same but it's not as good as getting from same engine

The only similarities between the 4G1X engines is the fact that they are 4G.. 4 cylinder and runs on gasoline. So it should be 4GXX because the 4G1X does not share that many parts

Furthermore, the 4G18 engine is based on the post 96 lancer design, meaning the engine is rotated 180 degrees with the timing belt on the driver side. It almost has no similarity with the rest of the 4G1X family...

Think of it this way.. you have 6 children.. all with black hair and black eyes and they are all part of the 4G1X family.. while the 4G18 child would have blond hair and blue eyes..

Nice way of putting it
Well, can I at least use the pistons from the 4G18 on the 4G15?

P.S: What's the engine class for the 1.8 Wajas?

fit oversized piston on 4g1x engines???>... possible??...
of course need to rebore the block first la...

the answer is .... nope

I was wondering, is the Proton Waja the first to use 4G18?

No, that engine came from the Lancer..

Which particular generation of lancer? I knew it came with the latest 1.6 Lancer, mated to INVEC III CVT gearbox.

I'm not pretty sure the chassis codes for Lancer, but it should be the one which had different platform than Wira

u can actually increase the cc of a 4g15 to 1.6 by using the 4g18 crank, conrods & pistons.

what about the block height and cylinder bore size?

lol bro, he obviously has not done enough homework yet...

definately needs a rebore, as for the block size, it remains the same. btw, have done this mod before.

You mean you've done this mod before?
How are the results? Good?

P.S: Dude, you've been posting quite a few [WTS] threads around. Hope you could manage them better Your stuff is really enticing, but without pictures or testimonials, it's kinda hard for us to judge anything Hope you don't mind the open comment

no problems! if u wanna see the stuff, give me a call, no oblightions at all. i don't have a digital camera to take the shots:-( maybe if i can sell more stuff, i'll be able to afford one.

as for the mod job, i have two customers running 4g15 engines stroked to 1.6 using those waja parts. with fast road spec cams, a ported cylinder head and a piggy back ecu, we managed to get 125hp on wheels.

Dude, I'm also running oversized pistons on one of my Saga's. Went for an overhaul & was rebored (...standard overhaul practice, right? ) to it's final possible rebore size (...any idea what size?) But I'm not sure if these pistons are 1.6 pistons or smaller/larger

Is reboring a 4g15 block to fit 1.8 pistons a little too enthusiastic?
Anyway, the 4G15's in question here is from a Saga Auto. Say "carbie"

damm enthusiastic not seen that done b4. donno what size u rebore to, btw is it the first overhaul for that engine? if it is, u still can go one up, but to fit 1.6 pistons would be pushing the limit.

Yes, it's the engine's 1st overhaul... BUT according to my mechanic, there's no where to go after my final rebore. They messed up during the 1st rebore & had to take it all the way to the end I guess I'll have to use this engine until it's dead No more overhauls

Anyway, UGPM

too bad. how in hell did they mess up on a re-bore?

so is 4g18 engine good?

Good~~better than my 92p at least in terms of response
Mine like crap XD

obviously u hav'nt realised the full potential of your 4g92. on the other hand, the 4g1 series engine has a reputation of being a bullet proof engine. as for the 4g92, hp figures are easily realised as there are more stuff we can do for the 4g92 engine.

of course, no money so compare stock ler
Stock performances alone, Waja way better

even if comparing stock to stock, i still find the 4g92 better as if gives me the option of manually tuning the car.

Tuning different already
Anyway, planning to add hi cams to my 92p, wanna release its potential

wah... how many degree 1? later becum monster d... ur new year present for urself is it? hehe..

what kind of cams are u looking at?

Maybe that's because of the low-end peak torque nature of the 4G18. But i'm finding Wira 1.6XLi manual a more exciting car to drive

It depends on my budget....maybe regrind cams too or custom made

well, 1.6 cams are going for rm1350 inclusive of installation, if u're interested........btw, is your engine in good shape?

yeah engine in good shape, haven't reach 100K yet

what else have u done to the car?

So far just some minor mods like exhaust system, air filter, spark plugs, ground kit + VS, thats all for my engine
But pickup still slow due to the auto transmission

before u do the cams, better get an oil cooler for your gearbox. sort of light an insurance policy on the box. those boxes are known to be quite fragile.

ok, still waiting for it to KO, then convert to Manual

bad boy

XD
Kinda fed up also, accelerate quite slow so wait loh still KO, then manual datang XD

hi maddriver, is a 4G91 engine good?i'm goin to swap it from a 4G15 carbie to 4G91 EFi.. been plan that long time ago but not enough budjet.. what are the price for fully convert? auto only

4G91 engine good~~
A lot of ppl using 91, then rojak with 93 parts XD
Full convert should be around 3K I think

This post has been edited by shinjite: Jan 1 2007, 01:39 AM

i think now gonna need around 5k to fully converted. the h/c oso wanna around 3k d.

Raise price a lot already these days, sad man~~

auto wo.. not manual
last 5months i ask bout converting.. manual 6k, auto 3.5k

auto ar.. i think will cheaper around 1k-1.5k only. should be 3.5k-4k lo..

auto half-cut currently are sold for 3k+ as 4g91 now in demand, chopshops are raising the prices. my labour charge is 1.5k, stand by 1.3k for all service parts, eg. timing belts, lubricants, brake pads, bushes, etc.

fully convert also around 6K already for auto alone including everything

wah.. increase again ar....

auto is way cheaper, if you go for manual because its more on demand, expect 4K or more for the H/C

Even for MIVEC, manual and auto difference by more than 1K

the only bloody thing that has not increased is my labour charges

maddriver, not only that, wages too
Everything increase except that

if both oso increase den gonna think twice lo when wanna transplant.

labour is my wage. toll also just gone up, petrol comming soon........damm fed up!

Its like that 1 ler....gotta cope up with it...if not, no choice loh
I need to use public transport, luckily still can car-pool

i also got it.. coz i stay wif my fren who same course wif me..

bro madman...where can i find 4g18 waja crankshaft? Usually how much is the cost to bore n install the stroker kit...
thanx...

u'll need a waja engine kosong, about rm2k. parts, machine shop charges & engine balancing will set u back about rm3.5k. my labour rm1.5k.
