The original daewootech forum

well, just told us your original tire size, and i will answer :) but, like on my optra, the tire are stock on 15inch, 195/55/15 to go like 17inch, i need to put 205/40/17 tire to stay under the 2% tire diff. like. to get the stat for your tire, just use the page there > http://www.1010tires.com/Tire...

huh, then whats the point of showing us that part if no idea if it work and what it do?

it may be a random pic from ebay, who know

be sure to get anther timing belt too, usuaully it's driving by it, so, that will kinda help your motor to run finner i guess

5w20 dont seem pretty good to use in that engine, i would use at minumum 5w30, but only my 0.02c

my optra does the same thing (optra aka forenza / nubira) even if odd, i found that on higth octane gaz, it make it more after the 90km/h, like the waiting to bypass another car (from 110km/h to 140km/h in example) than on normal octane gaz, else i always get that waiting state i kinda put the fault...

They already sold 'em in canada, optra 5 they call it

I hve an optra '04, wich is the same exact model as yours, and on mine my gm dealer installed mud guard, so i knw they exist for your model.

*bump*

I'm thinking the custom route is the way to go. My Meineke guy in town quoted me $150 for a Magnaflow stainless steel muffler installed, plus another $100 to replace the resonator. What diameter pipe are people thinking is ideal. Stock is 1.75in. I'm thinking at least 2in or 2.25in. I think 2.25 is...

Well, i misread it, but i thougth u wanted to shift/gear faster, and you actually can change your gear ratio in the ecu, and thus, affecting your transmission

I would love to have that spoiler, look really nice

I hope the car will travel to canada, maybe i will be able to steal the spoiler... j/k

Well, you can maybe program the ECU, will maybe be a lot less costly than changing it. But you need the tool, and only a gm shop will do have that, try asking them.

Awsome work man!!, nice too see some expert make work for the optra5, and other car on the same chasis!

It can be a simple bad gasket or seal.

Best thing is to locate the leak, go on a clean surface, and verify where it leak, and/or clean a bit under your engine with a towel (where it's the more 'oily'), and check where 'fresh' oil pass by, my .02c

for a header, im interessed, but like Wolf-Spirit said, i will prefer already made to 'fit', but if it need minor change to fit i dont care too. 2.5 piping will be the best for me i think, no need for 3''.
