A few days ago I just purchased a new project car. The previous owner had a local shop here in hawaii by the name of WMR (Wicked Machine Racing aka Wheres My Refund) swap in a B16. It was a bad motor so they replaced the block with a GSR bottom end with type r pistons and rods. I took over the project wanting to go all motor but i verified that they ripped off the guy and installed an LS tranny with the B16.

I wanted to go all motor but i guess i will be going turbo since the car has the LS tranny and i have a few left over turbo parts. Anybody have experience with a turbo B series motor with an LS tranny? It seems like the gearing is soooooooo long and falls out of its power range when shifting.

 

uh, its not that much different than a GSR tranny. its not ideal, but its still not a horrible trans. just make sure u set vtec a little lower so u stay in when u shift.

 

ohh trust me, its very different.

 

its much different form a gsr tranny. gearing is way to long, especially for the torqueless b16. id try working out a trade, youll thank yourself in the long run.

either that or swap out the final drive, itll help a bit

Yeah, that makes it a GSR motor with a GSR stroke and GSR torque, not a B16. The LS tranny wouldn't be too bad with this setup, but I would personally swap to the GSR trans.

 

**** my bad. i skimmed thru it. either way im still sticking with my statement

 

It will be fine.. as long as you appropriately size your turbo, you'll stay in boost. I love my LS tranny.. can't beat 3-3.5k cruising 70-80 on the highway.

 

Screw the LS tranny and freeway crusing... get yourself a B16 tranny.

 

theres a guy here selling this....



can a GSR or ITR final drive fit?

 

um, its really not THAT different. i swear to you. this is coming from someone who has owned EVERY b series tranny that honda makes minus the ITR. my ls trannies were great with boost and i loved highway cruising with them. my GSR tranny went very well with my ls/vtec and my 91 integra with a b16 went 15.6 and STAYED in vtec. and the one i have now, my cable b16 with 4.4 final drive works wonders with boost, though i sometimes wish 1st gear was a little LONGER and 5th was a little longer. cruising down the highway at 4200 rpm at 80 gets annoying sometimes.

bottom line is. boost the car, then worry about the gearing in your transmission

but you better have a good tuner, that motor has ALOT of compression with the R internals

 

A B16 tranny will make your car accelerate faster period. The only thing an LS tranny is good for is an LS motor revving to the stock LS redline. It will not work that well with your high revving B16 and it will just slow you down. If you want something in the middle if you cruise on the freeway a lot get a GSR tranny, but for all out performace go with a B16 tranny.

 

This may seem kinda weird but if i go turbo i dont want to have to worry about gearing. Now if i was going n/a then i would be willing to change the final drive. As it is right now when i down shift to third at 60mph, im well below 5000rpms which is way out of the powerband.

I guess what im asking is would the LS be ok for boost.

Thanks for your opinions.

my b16 with a tenth FASTER in the 1/4 mile with an ls tranny over a b16 tranny...and lost 1 mph.

this year i went 10.0 with a LS tranny and 10.0 with a GSR tranny. the gsr trans picked up a little mph.

ideally you want a slightly tighter trans, especially if running an oversized turbo.....but i can't figure out for the life of me why people act like having a LS tranny is like having a girlfreind with her *** welded shut or something

 

boost isn't a bad idea...were those itr piston/rings brand new if not i would do a leak down test then a compression check to start things off before you go boost...just to make sure everything is running correctly. LS tranny transmission are horrible as someone stated...if you plan on staying NA grab a shorter gear trans. b16 or even ITR...GSR does wanders with boost

 

im using an ls trans on a built/boosted lsvtec. 1 and 2 spins regardless, but 3 and 4 are a lil better at traction, and more fun on the highway, plus i commute 90 miles a day and the ls 5th is nice.


i would not recommend it for less than 300whp, at minimum, because it will rev kinda slow

I agree 100%. I would shoot for a b16 tranny and even a shorter final drive

this was the point i was trying to make. yes, either a gsr or b16 tranny would be better, but the ls tranny isnt the end of the world. just boost it and use a correctly sized turbo. especially cause of your better compression from the R internals. keep the ls trans, if you hate it once u boost, then change it out. but boost it 1st

 

b16 y21 or s80 with optional LSD. works.

 

What RPM are you guys seeing at highway cruise speeds with your B16/GSR trannies?

Reason I ask is I'm about to go H2B, and trying to debate going LS or GSR.

 

isnt the H2b the same as an HX50?? (H1E is hx40) if thats the case it would be WWAAAYYY oversized.. hx50's make 1000hp on v8's

 

my y21 in my SiR-II is at 3.5-4k at 60-70~ mph. 4k~ interstate 80mph driving.

It drinks the gas a little quicker but my lord you pick up speed so much faster in it.

 

Welcome to my world. I have a '92 LS. I purchased a b16 a couple years back and also bought a "JDM" S1 that turned out to be a US S1 which is the LS tranny from 90-91 integras. I was running that tranny with a turbo'd b16. You'd think the gearing would be horrible..but honestly, I love it. It hits that power band and just hauls ***..shift and take it up to 75mph..shift again and break 100. Hell, I broke 143 in 4th gear on that tranny. Personally, I'd stick with it. I plan to reinstall my previous LS tranny (gears are still good) when the new motor is finished. Ever ride in a nice DSM? Almost exactly the same gearing on those cars and they can be fast as all hell.

LOL... Exactly why you don't want an LS tranny. That's so fricking long.

 

any of you guys complaining of how much an LS tranny sucks just arnt making enough power.......ESPECIALLY the guys who are suggesting b16 tranny's with even tighter final drives and such.


you will learn to like the LS trans on the street when you actually have to take wheel spin into account.
