I know these threads come up at least every day about how much people want to get more power out of there motors. Everything from turbos, blowers, cams, computers etc. I'm also aware about the problems with upgrading power like weak drive trains and unreliable motors. I've owned my manual SWB SE vitara for about 3 months know and the lack of power just shits me so fucking much! Trucks overtake me on free ways! I have little toyota echos with a boot load of crap hooning past me. I've even taken the back seats out of my car so I wont have to deal with the added weight of passengers. My previous car was a 180sx with a 230kw SR20 and before that was a SR20DE which was still better than a g16b. I just don't understand why the G16b is such a weak motor. I'm thinking about doing an engine swap when my g16b blows up. All the other engines like 4age and sr20 will smash the drive train apart. So Im thinking a j20 with an auto box. Question is will it fit in se416? There's really not much on the net about this engine swap. I think I've read somewhere that the chasis rails are to narrow or something in a SE? So is it worth it or am I better of just selling it and buying something like SWB defender?

just fit NOS

What size tyres have you got?

[Fatzook]

Just sell it and buy a J20 factory vitara.

[Sweenz]

Ive got 33 inch tyres. I reckon I will just buy a factory J20. There worth it right?

[shep]

So maybe having tyres 7 inches bigger then standerd would suck a bit of power away. Maybe?

I think the vitara drive line holds up pretty well, I dont exactly go easy on my swb and the clutch,gearbox and diffs seem perfect still. I know of a hardtop vit running a sr20det and he hasnt had any problems either. Both setups are around 200hpatw. Lately I have been doing abit of towing also. I have never owned a na g16b myself, a friend of mine does though in my opinion goes pretty well.

Was it a costly process to turbo your g16? Would you say it was worth it? If you wouldn't mind could you give me a description of what running gear your using and the final cost?

[zook_ute]

I brought it done so I saved alot of money there. Probably 10-15gs. I got around 16g worth of reciepts lol. Not worth it in my opinion, would definitly be worth looking into a 4age conversion though. Im running a hd exedy clutch, standard box and rear diff. Steel diff upfront

And what gearing changes have you done to compensate the tyre increase?

[Sweenz]

It already has 5.12 gears at the diffs. Asides reduction gears what else can I do?

[gvzookdriver]

Why not just sit back and enjoy the drive who cares who over takes you. You bought a 4x4 not a street racer. Once you get off the tar you wont car about going fast

Arnt 5.12s stock?

If not what was?

Look at what % larger the 33's are over stock tyres.
That % would be the minumum increase reduction you want to get back some usable power and more importantly torque.

Just get a Defender

Atari you suck at trolling. Stick to what your good at which is giving helpul advice.

[Sweenz]

Even today whilst taking on some steep rocky inclines in 4LOW the car was bunny hopping all over the place even with my foot flat to the floor and and slipping the clutch. I dont know if thats a seperate problem from a lack of power or a fried clutch? I suppose I might as well get some reduction gears before I get a Defender. Guess you can never really have to many mods for your 4WD

i was lead to believe that i was pretty good at trolling... sorry i've been a bit off colour lately due to dealing with a deadbeat junkie brother & the suicide of a friend, will try to raise the bar for 2013.

33's on a 1.6 vitara must bring the massive suck, even with gears it's still going to be a POS on the road as they don't effect hi-range in a vitara...

you should buy a defender, join up to ALRO & moan about the shitty ergonomics.

[alexxx]

go the gv bud. You will never look back!!! 2.5l V6 goodness.!!!

[Chop]

Mr sweenz, can you confirm something for me please?
You say you have a G16B? You drive a 1990 swb which has a G16A as standard, was yours changed over to a G16B?

[DarkHorse]

Did wonder about that.

If it is G16B it doesn't sound all that healthy. Low range is still OK, although 33s must be pushing the friendship in all sorts of areas.

There isn't much you can do to the 1.6 to make the sort of improvements that are going to make you happy. The 2L is a significant step up, and your current mods will mostly swap straight over.

If you really want power, start thinking GV, or something non-Zook. For the record, the Defenders I've driven have had less guts than my old 1.6 (power to weight and internal inertia mean you have to work them even harder.)

Yeah it has been swapped to a G16b. I'm going to downgrade the tire size to 31's and I'm probably going to take it to a mechanic. Im starting to seriously think that there is a problem with the motor. As I mentioned if you take of in first gear no matter what stuaion now it bunny hops/jolts whilst the its trying to pick up speed. All the other gears seem fine though. It actually got me wondering though. Would a fresh g16b (as in a rebuilt one) be a worth while venture? Mine has about 200XXX on the clock so its pretty flogged. I was thinking a new on with maybe a bit of porting and polishing and maybe a tad larger pistons might make it feel fresh and alive again. Opinions?

My old lwb g16b used to go great, even with trailer full of work gear and 30" tyres on! Was up around 300,000km's!

[DarkHorse]

Sounds like your clutch is toast, or there's a fuelling/air intake issue somewhere.

Jolting or bunny hopping is not a symptom of a lack of power, it's an indication that you are not getting continuous power to the wheels.

200 thou is nowhere near write-off time for these motors. Most of them are now up around that and still getting around happily. Some have twice that and are still kicking along.

[Rhinoman]

When I had my 8V on 33s and stock gearing it would barely bit 60mph and needed third gear on hills, it was rubbish offroad as well. The 5:83s make a huge difference but the gearing is still a little higher than I would like.

[stewy91]

my guess would be your clutch is gone since you seem like the kinda person to spend more time on then off it

[Sweenz]

The clutch is fine it seems. Tried doing a few tests on it to see if it was rooted and all seems well. The problem is just isolated to first gear. It won't rev out properly. It jumps and skips along whilst I try to take off. Any other gear and it absolutely fine. Just first gear it the problem. Has anyone experienced similar?

[Rhinoman]

Maybe your shocks are past their best; you will get a lot more torque at the wheels in first.
