right now i have a 93 mx-3 sohc I've ddroped 50lbs in weight reduction
but other then that i'm stock
I'm thinking about doing 1.8 BP swap and I"m wondering how fast should i expect to be? will i keep up with civics? or should i go with something with more power..????

U do a BP swap u'll be in the high 15's to low 16's depending on driver skills.

even with the sohc u should be keeping up to the 4g cx,dx,si and the 5g civics cx,dx si would take u in the topend cause u have the sohc,but the sohc has good midrange power, unlike the above civics. but u definatly would love a bp as ud walk them

You mean sohc 88 hp to the wheels? SWAP.

Do a BPT swap or a BP Hybrid Turbo.

88hp at the crank. More like 70ish to the wheels.

A 4th gen SI would kill a Mx-3 (4cyl maybe the six as well), driver skill aside. As long as the 4g is not sporting a 4 speed or the lowest trim motor just about any of them should be able to take an sohc mx-3.

I also dont know if you have ever driven any of the cars you are ragging on either, the last 4g I drove did best between 3-5k rpm in thie mid range.


To the OP head over to 4 cyl performance, you can find a ton of information over there on both modifications and motor swap advice. For a mild motor upgrade or for future planning of a turbo setup, a BP swap is a good step in the right direction. There are a lot of odds and ends you can do in regards to weight reduction as well, just don't do what i did and take it a bit to far, it makes for piss poor rainy day drives.

lol i love the weight reduction, but seriously you got like 7-8 pounds in speakers and wiring in their....LOL REMOVE IT!

Noise levels get VERY intense inside a car that is as stripped as this. Part of the reason is to break the monatany and add a little bit of comfort.

What you see above is one of the stages of weight reduction, there was more done to the car. At last weigh in she was shy of 2000lbs.

Ok well i did my bp swap/with pro lx tranny....Also i have CAI, pacesetter Headers, 2.5" exhaust to where the old cat was and 2.25" the rest of the way...
~I've done more weight reduction....stripped back taken out a/c stuff in the bay and took out little odds and ends that don't do anything(towing hooks)...
and it's a pretty quick car now. gotta wait 3 more months until i'm 18 so i can run at the track....Then i'll post some times

It would be easier and cheaper to throw a 50 shot on top of it rather than stripping everything out of the car. It also makes for a more pleasant ride..
