How about turbocharging a NA VR4?

if buy the VR4 ecu, can plug and play?

if the engine its a 4G63 DOHC yes you can plug in the vr4 ecu , that would be better , cause you don't need to do any installation & tuning .

the whole process is like re-inventing the wheel... drop the idea and drop in a halfcut

not everyone with budget , if i were to turbocharge the 4G63 DOHC n/a i`ll do like this .

1. vr4 pistons & conrods
2. vr4 turbo kit
3. vr4 injectors , fuel pump & ecu .

cheapest way to have more power & be like anyother vr4

the NA engine block or head can tahan so much pressure meh?

i tot they use diff material to build turbo engines... :huh:

vestax,
I'm not too sure of the exact pricings... but if u're going to rip the block open to change the pistons and conrods... further more purchasing everything (literally a halfcut) just without the block and head itself... would it not be better to directly drop in a halfcut? Workmanship ain't gonna be cheap to open the block... whut more, reliability isn't necessarily going to be there.


If u're on a tight budget... but die die wanna turbo kit... then go low boost with stock internals. The moment u start changing your internals... u'll end up spending almost the same amount (if not more) than dropping in a halfcut.

its not the pressure u're worried about... its the heat and detonation. n/a heads produce a higher compression... i guess it kinda depends a lot on the tuner too.

[/b][/quote] well it depends on the mechanic it self , some mechs open up the oil sump and then take out the conrods & pistons from below , that would save time , without taking the whole engine out . like many people would suggest turbo kit , cause basically you aready know your engine condition , rather then buying a halfcut and fit it in and then later find out there are problems with the engine . alot of people are doing it in the states , basically the n/a block & the turbo block is the same , just that n/a doesn't run on oil squiters , while the turbo block does . say if you could source parts like pistons , turbo , ecu , injectors for a very cheap price , then i say its worth doing it . if money is not the factor , then obviously transplanting would be a good choice right ?.

but turbocharging the NA 4G63 is more challenging..
thus will make u happier with the results unless it's a failure. :D

but i duno bout other ppl lo.... for me i feel that it's quite an interesting n challenging job. ;)

 

[edgar_raphael]

If you already have a 4G63 NA, then it would be a good idea IF you can get the parts second-hand, cheap. Dont go further into the engine internals, cos the cost is going to be expensive already. Just take the turbo and manifold and bolt them on. But you can only play soft la, and also remember to calculate the budget first, if over, then drop in halfcut more worth lo.

Too much power in front will make the car understeer even more...

That's why original VR4 has AWD as standard...

U can ask any one who put VR4 engines inside Satria / Wira/ Putra and they will tell u the same thing... the car understeers easily and as a result, the fun of driving FF is gone. Good for drag only.

forget to mention Saga also.....wahhhh..cannot corner lorr.... :P

wa... so hard ah? :lol: :lol: :lol:

so when u corner u corner at 20km/h oni izit??? :lol:

the meter is 80-90 litdat....but evo5 over passed my car suddenly i feel like i'm cornering at just 20kmh....hahahahha...subang corner.... :lol:
