i didnt know that.

so thte manual looses a lot less power... if you shift right?


does anyone know the difficulty of swapping transmissions? like do you have to take the engine out or anything rediculous?

Yes it would have to be removed. It is not a simple project at all. And the only thing holding back an auto is the gear ratios. Autos shift faster that most humans can and 99% of pro drag cars use them because they are consistent the right tq converter and even a stall will do wonders to just a normal auto. but you will lose more hp through the drivetrain with an auto over a manual.

That depends. If hes switching an auto out for a manual, then yah its going to be alot of work. If hes merely switching one manual out for another one that is compatible (such as D16 for D20), then its not so bad. I can swap my transmission out for a new one in 1 day without pulling the motor, altho I do it at my shop which has hoists and full set of tools.

right the power is more direct and you control the shift points and reduce shift lag-big downfall to auto transmissions.

so to just reinforce what i said, if both our cars were stock and we raced and i didnt mess up on the shifts, my car would smoke urs. i aint puttin your car down just tryin to make an example u can easily relate to. and thats the catch with manuals, u have to know ur car i.e. where to shift on ur rpm band, how to slam into the next gear without droppin ur trans or grindin out. the manual is more difficult to drive (obviously) but the benefits are def. worth it.

ah my senseless ramblings lol.

My car is a manual, and my car could probably beat yours

So I'd be swapping from the d16 to the d20.

PrecisionBoost (tom?) said it is a direct swap with same mounts and everything so that makes it easier.

oh sorry, the way u were talkin i thought u had an auto, my bad. i shoulda remembered from the meet lol. yeh i think u have more done to ur car than i, its cleaner anyways lol.

PrecisionBoost (tom?)

Chris.

Tom=GSIturbo

They are buddys so it's easy to confuse them

yeah thats really true.




so its true id have to lift the engine out/drop it however that works to swap transmissions?

Well im ordering the cylinder head this week, and daewoomofo from daewootech said he would give me a lanos intake manifold if it fits the aveo cylinderhead. so i can get that polished too.

So with CAI, full exhaust with a header, Port and polished cylinder head & intake manifold, and Cams... Do you think I'd hit the 150 HP mark with out high compression pistons?

That would save me a boat load of money.

Didn't see anyone answer this so I figured I would save you some time... The Lanos IM does NOT fit the Aveo cylinder head. The runners and bolting are off. Y2Daniel and I got one last summer to port for his Aveo, and it didn't bolt up. If you get the Lanos head, it will bolt to the Aveo Block, and then you can use the Lanos IM...

Daniel left it at my house when he moved to Michigan, so if you want it I'll sell it to ya... It's acid ported quite nicely...

I am probably going turbo this january/febuary. so i'll probably just keep my stock intake manifold. thanks anyways. boost up around 150hp and 150ft/lbs of tQ. Then maybe the followsing year if i want more power ill swap transmissions for the suzuki forenza D20 transmission and boost in the 175-190 HP range

so has it been verified that the x16xe pistons and rods works in aveo blocks?

I am also in the process of building up my engine internal. Mine is a 1.4DOHC (77.9mm bore X 73.4 stroke). Just bought a 2001 Lanos crankshaft, hope to stroke it to 81.5mm stroke which up it to 1550cc with the current 77.9mm bore. If the opel/vauxhall piston fits, then I will either get a 80.0mm 8.8 compression piston for turbo or 12.5 for high compression NA.

Still not quite decided which way to go. NA or Turbo. If NA, with 80mm bore X81.5mm stroke, its abt 1639cc. If I use the lanos cams with 9.2mm lift, I duno what horse power I will have.

My current horsepower is only 83 at the wheels and 99 on the flywheel dynoed. Its port and polished head, shaved head (not sure whats the compression, but can feel the increase in compression efficiency and power), 4-1 headers, decat, aftermarket muffler, walbro 255 fuel pump, SARD fuel regulator at 50psi during idle, AEM CAI with open pod filter. My car last time without mod is only 70hp on the wheels. After doing all these, only gained 13 hp. Now planning to do more.

the x16xe pistons work for the 1.6 engine in the Aveo, But probably not the 1.4, Not positive.... but im thinking no.

There are many mixed opinions on whether to go Turbo, or NA. you wont be able to get much power by going NA, and much of the power that is made is way up the high rpm which the aveo cannot get. With the turbo, It can be more unreliable than NA.

I was going to go turbo since I have a speed shop in town that builds many custom turbos and has a dyno and can do all the tuning right there. But now I am just going to put my Headers on that are being made by gse_turbo. I am currently gathering fund to buy an Acura RSX-s that I am hoping to have by the end of 2008. With that car I am going to do all the things I want to it (450HP... Thank you K20!)
