I've tried both a dx and si tranny, and i'd have to say the si trans is much more fun for toolin around town. You stay in your "power band" much more on the si than the dx, but right now i have the dx in and it is kinda nice to cruise down the highway doing 90 and pull about 3500 rpm in fifth gear. The si trans used to scream at 90 mph :P Not to mention i have to shift first gear fast as it is on the dx trans...the Si trans used to be too quick, and i'd end up over-revvin stuff

 

you guys selling those trannys ur pulling out?

 

I agree with you and boost... but it does suck *** driving in high rpms, with my hybrid tranny I was like 4500-5000rpm in 5th gear for like 80mph that REALLY sucked *** with my old crx (straight 2.25 exhuast, under the gas tank, no cat, and a fart can, it was extremely loud) The dx tranny is great for driving on the freeways with but having it paired with the d15b2 sucks ***. how to fix? add boost. problem solved. driving around runing 8-10 psi makes up for the longer gears and it is easy as ---- to makes passes and such on 2 lane highways.

sure the si tranny would be a lot quicker racing and ----, but the dx is more comfortable on the highway(and i travel a lot)

 

Thanks for the input fellas. I will be doing a good bit of highway driving and I figured the dx would be better for the highway, but I didn't want to be disappointed when I run the 1/4. I think that with me boosting I probably wouldn't mind the dx trans. I was happy with the si trans and boost but since I do alot of highway driving I may just like the dx better. Anybody else have 1/4 time difference? I also have one of those phantom grip lsd things and I'm trying to decide what trans to put it in.

 

if you plan on putting the phantom grip lsd differntail into a tranny, it is going to have to be the SI tranny. ...

Why? becuase the dx has a 35mm bearing and the si has a 40mm bearing.

I'd be willing to bet that the diff is a 40mm bearing

 

Wow! That is good to know. Thanks

 

Outer diff bearings sizes do not matter for the PhantomSLIP. The diffs are the same spiders and cross pin.

Dr. Boost, thanks for the linking.

Also, DMoore's site has misinfo on the gearing, I sent Dave the proper info, he never fixed it.

 

glad to see you around these parts mista.. You probly dont remember me.. but I remember you from the resource when I was a young guy.

 

never spent much time resource, just the main CRX page, which is where I got started.

Already learned alot and I'm not even looking into turbo's.

Wait for the AKSC supercharger setup.
