for boost which would be better?

[ragingxtc]

i searched the board, but i couldnt find the answer to my question.. which is this: if i were to build up an engine for boosting (from, say, a t3), would it be better to do it with a 1.8l or the non-rev-happy 2.0l? any info or posts would be great.

thanks in advance,
kiel

most of the kits out there use the 2.0, are you planning on going custom?

it would be a costom project that im considering taking on this summer. what i'd like to do is basically build up a motor as i get the money, then drop it in my '03 lx. i'd most likely use a stand alone, so wiring compatibility isn't really a problem. that brings up another point; does anyone make internals for the 1.8l?

I'm sure you could get internals alright. If someone doesn't stock them, they may have to be special ordered. It probably wouldn't be a bad idea to talk to a few piston companies and find out what they offer that would work well with your potential setup.

The 2.0L is basically just a stroked 1.8L...You will make more power with identical turbo kits more or less on the 2.0L FS, but you will make the power in different areas...The strength of the two engines physically is pretty much identical, and the FS supports a larger clutch and flywheel from what I remember....

also the higher piston speeds of the FS will be better for spinning a bigger turbo, but it all depends on what type of parts you are planning on running...

Any FS 2.0L turbo manifold will bolt right onto the FP, so plumbing is the only thing you really need to look into custom wise...which won't need to be changed to much over the FS designed plumbing...

i would go with the 1.8. it is superior in drag applications due to the power made in the high revs and the fact you will always be in the powerband.

as far as having a bad transaxle, smaller flywheel and clutch, that is true, but the 1.8L motor can use the 2.0 transaxle, and will bolt right up. so pretty much all you are looking at is building your transaxle a little and building the 1.8 for a completely compatible drop-in.

with the right internals and boost application you should smoke anything on this forum.

since you have to order new pistons anyway, i would overbore the head and get lower compression pistons (ie 8.5:1 or 8.0:1) while youre at it. this should give you a little more power and let you boost more.

First of all Hi-Perf, you don't overbore the head ...you overbore the cylinder chambers for larger pistons...Second: these blocks do not tolerate that very well, other than normal amounts for overhauling...You can't overbore enough to pick up any significant displacement, and in the end it really isn't worth it for power...

You absolutely have to lay down what you want to do before you choose which engine...Stroker engines do very well with turbocharged applications, and I bet it will be easier to get the most power out of the FS, and you definately will get more boost-on torque...the old adage of displacement becomes apperant in this one...But it all depends on where you want and need the power...

 

[hi-perf]

you are very correct, and that head thing was my error...lol but you know what i meant

anyway you can only overbore a little like 3mm or something, not very big but every little bit counts, and you might as well if youre ordering custom pistons anyway.

for a drag application, i think thats what hes aiming for, honestly they will probably be the same, get whichever one is cheaper or easier for you to mod (probably the FS-DE). but ill stick with my FP-DE for now, i just like the rev-happy part.
