need help for engine mods in a 4g13p proton saga engine

[bobrio]

my suggestion is port'n'polish the head,change the cam(if got $$$),cluth,flywheel change to super touring,gearbox change to 1.5 wira(if cannot just change the fifth gear to wira 1.5),and the best is find for weber 1.3 carburator(quit had n $$$)....you can tapau 1.6 easly and can neck to neck with 1.8...:proud:

and dont forget to change the exhaust system to 4-2-1 and open pod air filter...

4g13p=1300cc
4g15p=1500cc
4g91 =1500cc(injection/carburator)
4g92 =1600cc
4g93 =1800cc
*mitsubishi
4g93p =1800cc(putra/gti/wira)
*p=proton

4g15 + jasma highcam (extra 10horse) + weber dcnf (another 10horse) = chase toyota altis

cost:
-4g15 blok (if u can find from ppl convert to gsr) = RM500-600
-Jasma highcam = RM5XX ??
-Weber dcnf (enough d coz u need to drive daily) = RM650 to RM800

- 4g13 gbox for super low torque pull, feels great for 0-160kmh (I tried 160kmh all the way for 150km distance, it overheats)

- 4g15 gbox for smoother, petrol saving and better top speed 180kmh (This one no overheating)

Totally calculated your 4g15 by now should be putting out 90hp++
(stock 4g15 injection from wira tricked out 81whp with some "enhancement")

You should be look at 8-9seconds for 0-100kmh. but the money u spent, can find a 4g91 which is powerful and petrol saving. I hv seen 4g91 rojak mivec head making 100whp, not bad for a 1500dohc. but tricking out your 4g15 also just fine, the feeling of using 4g15 to kick altis' ass feels good.

just the 5 gear is it?

ahaha..

tq

 

[Newbienissan]

as far as my noob knowledge, 4g13 and 4g15 gbox are different. the ratio is different. coz to coupe with different power.

i think lembap is coz due to the horse power different

wat about 4g13p with 1.5 (iswara/wira) gearbox and 1.6 wira gearbox. any effect?

 

[Newbienissan]

different displacement engine will have different gear ratio n final drive.

however, ppl do use bigger cc engine but retained their lower ratio gearbox, so it pulls much better and torquier.

factory made gbox ratio to match the engine displacement, their goal is to output optimum power n fuel saving, not performance or acceleration.

example, if using 4g13 gbox with 1500cc engine, 1st and 2nd gear can wheel spin like nobody biz, and playing between 100-170 is fun, but maximum is about 170kmh.

if using 4g15 gbox with 1500cc engine, 1st gear wheel spin only, 100-170 is not as fun as 4g13, but better top speed 180kmh++

but some claimed the new robocop design saga with 4g13 engine n its gearbox can hit 180kmh, maybe their gbox also different again. have to check the gearbox code.

anyway, 4g13 and 4g15 gbox codes are different

wats your suggestion,
if i want to still used my 4g13p engine..
do i need to change my gbox to 1.5 cc or 1.6 cc ones..
or just maintained it..

currently im using iswara lmss..
wif simple mode..

 

[Newbienissan]

just find a 4g15 blok n plonk into it. when u have more $$$ get weber dcnf. that's enough for 4g15....otherwise u will be spending too much n regret coz u can have better engine swap for all the $$

just used 4g15 block? iv done my p2p n oversized to my 4g13.. eheheee..
dcnf? currently using it.. but still trying to tune it.. webber is oke, just that its choke doesnt work, so morning have a difficulty to start up my engine..

 

[Newbienissan]

then just get the weber dcnf, good enough :)

using weber, b4 u start the engine in the morning, pump ur accelerator a few times. then let the engine revs 1500rpm for 30 seconds. kautim. for the aircond solution, maybe ficd will solve the problem on aircond idling

thanx 4 d trick.. eheheee..
btw, currently im using a 16 inch rim, taiwan.. my foreman said that it is heavy..
do u have any suggested rims fitted to my car.. as i know, the bigger the rims, the larger the diameter.. then long can play good enough.. if let say i change to 14, my long will reduce is it?/

 

[Newbienissan]

14" inch will be perfect. 15" still ok if u use 50series sport tyres but its not going to be comfortable.

i will recommend 14", coz saga so light doesnt need 15"
