hi people my w202 has a 1jz under the bonnet for a couple of years.
and I have two main issues that I couldnt solve.
1)
Car is a 96 c220 and I am not sure what the diff ratio is. It is now matched with 1jz box and the ratios are screwed.
speed/7000rpm for each gear:
1st: 96~98kmph
2nd: 166~168kmph
3rd: 240+kmph
4th: cbf
as you can see the gears are pretty damn long. It has barely 3000rpm while cruising at 180kmph.
It was however still very nice to drive with the 1jz and stock ceramic twin turbos that spool instantly.
although 0-40kmph is a little sluggish, it was still acceptable and managed 6seconds 0-100kmph with the stuffed ratios. (with proper ratios and 1jz stallie it should hit 5seconds)
the real problem came when I replaced the stock twins with bigger HKS twins.
the car has absolutely NO POWER anything under 60kmph. (tho when it pulls it pulls hard)
the turbos hit full boost (1.1bar) at around 3800rpm, which is pretty good for the power they can produce.
however due to the ratios I will be doing 60kmph at 3800rpm @ first gear.
the car is very sluggish from a standing start, but its fine when the car is moving already.
so question is, is there any differentials with a 4.0 (or anything above, 4.3 with LSD preferred) ratio that will bolt straight up to a w202?
I have seen people modifying the flange and diff cover so they could use the diff from other models or makes.
but how reliable will that be? longshaft and subs will need modifications too i suppose? anyone here done this before?
2)
I understand there are a few turbo'd w202 on the forum I am wondering what are the sizes of your frontpipes?
I have been wanting to upgrade my dumps and front pipes but there are metal bars in the way and my 2.5" barely fits in. the metal bars (from the body i think) form a square which my front pipe went thru. I have 3.5" all the way to the back after that "Square" spot. I really want the bigger twins to breathe better so it would be nice to see if you guys managed a bigger front pipe.
sorry for the wall of texts but i think its better to give as much info for easier understaning.
any thoughts?
You'll need a diff from a 190e 1.8. It has a 3.46:1 ratio. 4 speeds? Are you using an auto? 3.5.... Why do you need bigger turbos? Bigger isn't always better.
What kind of internal engine work do you have done? Rods, pistons, cams, crank, port, valves, valve springs?

yeah its an auto. what is the diff ratio for w202 c220? I think 3.46:1 is too low and i need a 4:1 or above to shorten my gears.
as for the turbo upgrades, one of the stock ceramic twins went boom (very common), and I wanted a little more power hence the upgrade.
as mentioned the bigger twins hit 1.1bar @ 3800rpm which isnt too bad at all.
if im cruising at any speed higher than 40kmph and i plant my foot i will get the punch in a second,
its noticeable laggier than the stock twins that deliver power almost instantly tho.
I would say its the gear ratios (97kmph @ 7000rpm on first) that make the car sluggish while taking off.
engine is pretty much stock with the basic supporting mods.
and a pair of 264' cams going in soon.
if you know about the jz engines you would know the stock internals can tolerate a fair bit of abuse before they fail.
cheers
Yeah they can handle that amount power but you'll need more than turbos to make that kind of power(unless turbo lag is what your going for). Ok youll need to find a rear diff from a 190e 2.6 from 86 (201.029) 5-speed manual which has a 3.92 diff ratio, and good luck with that! You can see the diff ratio stamped on the housing.

car currently has:
front mount inter cooler
open pod
exhaust
bov
boost controller
afc neo
big twins
and i have got these going in soon:
550cc injectors
fuel cut defender
264 cam's
new coil packs
but if I dont fix the gear ratio issue I will still be left at the lights.
I think the car will be a lot less laggy if I had shorter gears.
so the diff from 190e 2.6 manual is the only choice I have?
there is no way Im going to find it considering I have never seen a manual Benz in my country.
Im looking into a high stall torque converter as well which should help launching the car.
If i could launch it with a 4000rpm stallie then perhaps a diff mod may not be necessarily anymore.
but with proper gear ratios it should be better to drive around town.
Do away with the auto, you're wasting your time on that thing honestly. You can also try a diff out a E220 manual. I wont lie these diffs aren't easy to find. Best thing if you want to keep that auto is have a custom rear diff setup. Other than that keep on looking for that diff
yaeh I do understand it would be a lot more fun to have a manual. My original plan was to convert it into a manual 1jz. but it is impossible to find w202 manual consoles/paddles/cables over here. ALL benz came auto from the dealers in my country. so I gave up.
but hey proper setup auto's are the killers down the strip :P
Do you have a manual 202?
Why don't you try using the toyota manual trans? If you want to use a benz manual you'll have to make an adapter plate, Manual benz transmissions are easy to find, people just don't know about them, My 202 is an auto but I'm keeping it that way as a cruiser. Both my 190e's are manuals. I swapped one of them from an auto to a manual. I had an extra manual trans setup not to long ago but I sold it to a buddy for $250. Your going to want a manual trans out a 190e. Its the same transmission housing as the manual trans on the 202. The main difference is the input shaft (on the 202 its shorter). If you really want a manual trans setup I can contact some one, It'll run about $800.Originally Posted by evevevevev

I intended to use the toyota tranny when i was doing the 1jz conversion. it was the little pieces needed for the conversion that put me off.
I will be staying auto for a while but my heart still leaning towards manual. i guess there will be a manual conversion in the future.
can I get my stock diff modified to the ratio I want? also can it be modded to LSD (apart from welding it)?
also my front lower arms bushes seem to be failing and failing again. could it be the extra weight from the heavy metal 1jz thats causing it?
any solution to solve that?
Im sure you can go to a performance shop that specializes in axles to customize it for you. They can most definitely make it an LSD too. I run an LSD on my both my 190e's.(190E 2.3-16 comes with a factory LSD). As for your LCA bushing, what type of bushings are you using? Factory type or poly? It could be that they weren't installed right as well.

It is not easy to find a axles specialist over here but should be easier than trying to source some Benz manual parts. hate it w202 doesnt come with lsd from factory.
those bushes are OEM replacement and they were installed by experienced mechanic. Or do these bushes require extra care while installing?
They can wear out prematurely if they aren't tightened properly(You tighten the LCA while the is vehicle is level on the ground, if you don't, they'll always be under tension and wear out quicker). You can try using poly bushings. They're available online for $100 a pair.

ill pay attention when the next pair are going in. by online which website are you referring to? cant seem to find any on ebay.
You can try these http://auto-parts.fcpgroton.com/w202-control-arm--list (first item)
or get clk55 bushings which use a stiffer rubber insert.
Id get the poly bushings.

looks great. will definitely get one of these when the pair on the car are going.
"FCP Groton now offers a Lifetime Warranty on all of its products." <------ so the bushes are supposed to be THAT good? lol
