1.8 Turbo?

[Shane5425]

someone tried to take a 2.0L longblock's internals and put them into a 1.8L longblock?.. the different displacement didn't give a clue that they wouldn't fit? (poke)

if you want to get very specific, stuff like the valvetrain and valve headder are different, but nothing he had was anything that wouldn't fit on the 1.8L.

well, the hype was on the boards at that time, that the internals would fit, but the pistons hit a part on th lower block..

ahhhh, I see.

Well looks like it will work then? I heard that the FP-1.8 is better for force induction rather than the FS-DE 2.0 ,that i got on my Mazdaspeed. Correct me if I'm wrong. I just want to make 100% sure that this engine will work on my Mazdaspeed with no problems,what do you guys think?

 

[turbo fs-2.0]

What about the exhaust turbo manifold for the mazdaspeed,will be a few inches longer? I heard that the FP-DE block is shorter than the FS-DE? I just want to make sure that my turbo set up on my 2003.5 will bolt straigh up to the FS-DE 1.8 ,before buying the engine!

 

[Shane5425]

it will bolt on to it.. theoutside is the same.. i am interested in seeing the outcome of a 1.8l Turbo..

 

[Shane5425]

ps, i would put the mazda speed 2.0l head on the 1.8l block... if i remember right, doesnt the speed have differant cams?

I'm pretty sure the cams are the same, but don't quote me that.

 

[Shane5425]

like i said , i could be wrong too ..

 

[turbo fs-2.0]

No!! the cams are different at least the intake one, I just spoke to Ken from protegegarage and he said that it might not run right,because of the PCM is for the FS-DE 2.0 not for the FP-DE. Also the exhaust mani will probably sit lower and thus push down the J-midpipe on the car! The FP-DE has a shorter block Let me know what do you guys think?

 

[Shane5425]

all we can say is that there is only one way to find out...

 

[turbo fs-2.0]

what's that?

my OBX headder fits without having to bend the mid-pipe on my 1.8L. If the 1.8L has a shorter block, it's defentaly not noticably shorter.

I was thinking the same! , that the lenght on the block will not be a big deal butthe thing is I want to make 100% sure that it will work.Ken told me that is not going to run properly due to the fact that the setup on the MSP is for the 2.0 FS-DE Now if you turbo a 1.8 with a stand alone ECU or it's factory ECU It might work right! again correct me if I'm wrong?

the factory 1.8L ECU will starve the engine of fuel, there's no way you'd get it to work right with any psi.

So the MSP PCM will work ok? because they run rich as hell!

 

[Shane5425]

what's that?

put it in and see what happens when you turn the key.. lol

That's the thing I just ask you guys if it was done before or if Is going to work before I buy the engine? I just dont't want to buy the motor do the swap and find the hard way that it doesn't work! Well let me know

 

[wwpms6]

i don't think anyone on these forums have ever done this swap. i could be wrong though. i know someone on here is swapping a 2.0 short block in place of his 1.8, but thats because he bought forged internals and they didn't fit his block.

the 1.8 might be better for boost, but i don't think it is that much better. not like its going to hold a lot more boost, i could be wrong though. if you plan on boosting more why not just go forged?

1.8L should be good up to 16-19psi. I guess a good situation would be if you found a cheap 1.8L junker that had a relatively good shape engine for about $800, since that would be just a little bit better than a 2.0L, and dosen't come with the 3.5-4K$ completly forged block price. people talk about the 1.8L making up for the HP loss with more boost, but the 1.8L puts out 122BHP compared to the 2.0L's 130BHP, that's really not anything noticable anyway imo.

 

[turbo fs-2.0]

No!!! boost will remain stock!!!! ,the 1.8 swap is because i can get the JDM engine for $550 (my price) is super clean! and that's the only one that my supplier has for now! What I really need is clean low milleage FS-DE 2.0 but the only ones available are the older ones with distributor and don't have the knock sensor! I'm not trying to swap the motor because the 1.8 is better is because mine 2.0 is making metal due to a bearing failure!!
