ok so it may be a stupid question but i have the 1.8 and was going to get a 2.0 but the more i seach on here the more it seems the 1.8 is better. if everyone is putting internals , cams, and ecu from the 1.8 to the 2.0 . Pluse the 1.8 trans has shorter gears so whats the reason for the 2.0

one other thing if u can raise the comression by putting the 1 8 piston in the 2.0 could you just switch the rods in the 1.8 and get the same result.

 

other people is going to tell you search

but the reason for people putting the 1.8L ecu in 2.0L is because of 1.8 runs leaner then the 2.0L but you got to have 1.8L cam as well to make a difference 5whp if that...

i thought the 1.8L trans hold longer gears but i dont know...others will comment

sounds good about raising the compression in 1.8L with 2.0L rods but i dont know

 

well i guess the swaping the ecu after u put in the 1.8l cams makes since.

so i guess that if someone swaped pistons cam and ecu in a 2.0l they would just acive having a little higher compression 1.8l with bigger injector and would asome that people built more of the 2.0l because thats the stock engine for the tibs after 1997 .

but if anyone could tell me if switch the rods and head gasket in the 1.8 and maybe the injectors to the 2.0 would give me a higher comperssion..

 

wtf.gif ^^ um... what did you just say there? i only understood the last sentence

 

hrmmmmm.... I would think that putting 2.0 pistons in a 1.8 wouldn't raise your compression ratio that much at all.....because i believe the rod size isn't much different....

I think the only reason people mod the 2.0 is because its a bigger engine, so you have a little bit more horsepower stock.

 

I have 1.8 block, 1.8 rods, 2.0 ecu and 2.0 overbore pistons, whit that a lowered engine compression. There are a lot of parts between the 1.8 and 2.0 that you can play with depending on your goals...

 

The 1.8 block is the same as the 2.0 block.
The 1.8 head is the same as the 2.0 head.
The 1.8 intake cam has longer duration and more lift than the 2.0 intake cam.
The 1.8 PISTONS are domed on top, and the 2.0 are not.
The 1.8 rods are shorter than the 2.0.
I think the 1.8 has a shorter crankshaft throw than the 2.0, but I'm not quite sure.
If you swap only the 1.8 pistons into the 2.0, it raises compression ~ 11.0-1
If you swap the 1.8 pistons and rods into the 2.0, it lowers compression ~ 7.7-1
By swapping the 2.0 PISTONS only into the 1.8 block, Mauricio lowered his compression for his turbo, but he still has an engine displacing 1.8 liters.

So, if you want to raise compression in your 1.8, you'll probably need the rods out of a 2.0, but it's much much much easier to just toss in the pistons from a 1.8 into a 2.0, and snag the intake camshaft while you're at it.

To make it a 2.0, you'll probably need the entire rotating mass from the 2.0. But once again, you'll find it easier to just swap the pistons and camshaft.

Plus, the 2.0 is soooo much more common than the 1.8, which probably explains why more people use them.

And as that damned addage goes.... (don't kill me, please) there's just no replacement for__________. (you fill in the blank) cool.gif

 

^The 1.8 block is the same as the 2.0 block.

I believe the 1.8 is a bit shorter, I'll measure them to be sure...

 

sorry i havent been on to reply but i dont have the internet on the week days right now for im in the process of moving. but what AGreen had to say told me exactly what i wanted to know thanks.
and im going for more compression not less ...

 

turbo? fing02.gif

I think more people have the 2.0 because more tibs came with the 2.0 nana.gif
