Type R gear ratios and boost, will they mix.
Ahh.. Back in the FI forum 
Since fixing my car, I'm now at 151 WHP on a stock motor with CAI and advanced timing, my compression is 220 across the board, and I just did the 100k maint...
My eyes are back on speed.
I have a 94 GSR, bought a Type R transmission/clutch/flywheel when my GSR tranny decided to **** on me. My motor is healthy, I just about turbo'd my LS b4 I sold it for the GSR.. I think I'm finally ready to take the dive into the darkside..
BUT!
How good are Type R gear ratios for a turbo setup? If I go turbo I could always sell the tranny for 1200, pay 600 for another GSR tranny and use 600 towards the turbo setup... I just don't want to be shifting everytime I'm finally in boost...

Re: Type R gear ratios and boost, will they mix. (metal-x)
Actually for an N/A setup, the ITR gearset is wonderful. You want really short gears in a low-torque situation.
But going turbo, the LS with it's longer gear ratios would be more ideal. True you still want an LSD, but the ITR gearset and final drive would be TOO short. You'd be in 5th gear before the end of the 1/4.
A turbo'ed B18C del Sol here in Memphis back in the day swapped in an LS tranny from the stock GSR tranny, and the difference in acceleration was incredible. The longer gears stretch out the powerband.

Short gears are good for NA
Long gears are sick for boost. YOu engine works hard if you have longer gears, thus produces more exhaust flow and therefore keep the turbo working at it's limits much longer.

Re: (itr206)
What situation are you going to be in? Are you going to be dragging? It is actually better to have shorter gears like a B16 tranny or a GSR tranny, if you don't believe me ask Jinx, and some of the other professionals on this forum. You could possibly change the 5th gear, for cruising on the highway, but you would benefit from the shorter gears more.

Re: Type R gear ratios and boost, will they mix. (geminiGSR)
Here's a story for you.
Friend of mine had a '98 Type-R and we put a DRAG turbo kit on it. Set to 9 PSI, no other mods except open exhaust.
12.1 ETs at LACR!!!
Later switched to larger injectors and ACCEL DFI, the car ran slower at 12.6. It was "tuned" at Shitcrew here in the SGV area.

Yes longer gears will keep you in boost longer, but shorter gears (ie. gsr/type-r) will always accelerate faster, thus making you that much quicker...

weird..motormatrix has a itr tranny doesnt he???and he stops his pulls on the highway at the top of 4th gear..at 140

Re: Type R gear ratios and boost, will they mix. (GOLDBERG)
wanna know my opinion??
those who say the LS tranny is the best setup for turbo, has obviously never driven and/or seen a turboed car with a B16/Type-R tranny...
it's the best for both N/A AND for turbo...the LS tranny really really sucks!! ESPECIALLY driving around town off boost..

Re: Type R gear ratios and boost, will they mix. (TheSwift1)
the cable LS tranny is bad ***!
the gearing was changed in the hydro LS tranny to suit the girl driver
just like they changed the gearing in the 97+ prelude (the 92-96 prelude vtecs had much better gearing).

Re: Type R gear ratios and boost, will they mix. (geminiGSR)
it seems to work fine in my car.first and second are a little short,but that might be do to lack of traction, with 24" tires, my car is almost at 9000rpm at 128mph.

Re: Type R gear ratios and boost, will they mix. (turbotypeR)
Turbo wit ITR tranny rocks...at WOT its like driving an F-1 car because you go through gears really quickly. The only complaint I have (which is a highlight as well) is that you really have to shift a lot.
I still don't understand those who say "get LS so you can stay in boost longer" That make so little sense to me. You stay in boost longer because you arein the same gear longer..that's not good! The quicker you get up the gears without dropping rpms, the faster you will accelerate. Thats why F-1, CART, IRL, and GT cars have short gears...so they can accelerate out of corners faster.
Yes it 'feels' like you're going faster because there is longer gearing and the boost needle stays steady longer but in reality, a car with an ITR tranny will shift into third while you are still in 2nd and THATS when they'll overtake you!

LOL!! I WISH!! I f I were in 5th gear at the end of a 1/4 mile (without dropping RPMS) I would be going about 140MPH!! Sweet!!!

This entire debate gets so annoying and old. The real deal is about matching your motors power band to the tranny. IT'S THAT SIMPLE!
I can say from experience with my boosted B18B that the SiR tranny I was using at first was not good for my motor's power band. When you make 190 ft-lbs @ 2800 rpm and 227 ft-lbs @ 4900 rpm you really just pull through the gear too quickly to get the car moving with out mad wheel spin. When you shift you have to re-spool the turbo. If you only have 1500 rpm of range before you redline again there isn't much time to be spooling and accelerating.
Now if I had a redline that was 8200 rpm instead of 6800 it might be a different story.
Since the SiR tranny I have moved on to a GSR tranny and it feels really longin comparison. I would say that it's perfect for my fat, broad, low revving power band.
I do think that unless you have a turbo that takes all damn day to spool, running an LS tranny would be a bad idea.
In the end it's all about taking a plot of your power band in each gear and finding the perfect gear ratios to keep you rocking.

motormatrix had a type r tranny at 565whp and loved it. after blowing it up he went with a b16 with a quaiffe. it is all about prefrence

Re: (GRTechnologies)
hey turbo R , i know your sick of my questions now , but i like to know what to expect from my car 
, hahahaha
on those sliks are you trapping in 4th? or are you getting into 5th? im assuming 4th, but wanted to make sure , you still have traction probs with those things? what rpm you launch em at? what tire pressures?

Re: (itr206)
yes, i am on the rev limiter in 4th when i cross the line.yes, i am still having traction problems with those tires.i usually launch at 6000rpm.it depends on the track.i usually run 8-12lbs in the tires.
