Default Spec B's vs. JDM Final Drive... (Black R vs. RATEDR) *highway pulls*

Well, on the way to/ from Road Atlanta the other day, TJ and I got the chance to do some highway pulls with interesting results:

Run 1 (5th gear pull): I started to walk away a little bit.

Run 2 (4th gear pull): He started to pull maybe 1/4 car length and then I started to reel him in near redline. Very close...

Run 3 (3rd gear pull): He pulled on me a length very quickly, but then at the top of the gear, he had to shift (rev limiter) and I still had ~1k rpm's to go and pulled maybe that same amount on him!

If we would've had another chance, he would've torn me a new one in 2nd and 1st gear pulls. All these runs started at ~4-5k rpms and up to rev limiter.

Mods for each car:

I've got full toda b package (cams, gen 2 cam gears, toda valve springs, Portflow Ti retainers), toda header, godspeed test pipe, and oem exhaust. AEM CAI, and VAFC too. 175 whp with some "safe" settings courtesy of B18CXr.

TJ (RATEDR) has AEM CAI, JDM header, godspeed test pipe, and 5zigen (fireball?) exhaust. JDM 4.785 final drive and GSR 5th gear.

*Please keep in mind that these are my impressions, and TJ may have seen it differently. He should be posting up his side of the story soon.

Also, I had no passenger, but I did have the spare and some other miscellaneous junk in my car. I also had 3/4 tank of gas. TJ had a passenger, and had just filled up too.

We hope to do some 1st and 2nd gear pulls to really gauge the difference of the jdm fd (I'm thinking about doing this mod too).

Cliff Notes: toda b car vs. jdm fd car and the results were interesting. jdm fd seems like a nice *** kicker for the $ and for those who don't want to go into the head. Also less expensive, and no question about reliability.

Now for guys like Lip and sgT: would it even make sense for me to get the jdm fd? I mean if i reach my goal of ~200-210whp, will that fd even help in the 1320 or would it make me spin even more?

Your DAMN right I saw it differently! I waxed that @zz!...Ha Ha j/k.
Nope, my impressions are just as you stated them. In 3rd and 4th gear pulls I
pulled a bit on you due to my RPMS being higher of course, and then you came
and reeled me in...your car is strong for sure!

I think you should get the FD..Cause who cares about wheel spin when you are already rolling...i mean 200 whp plus the Fd...you will kill someserious people
on the roads!!!

Im not sure how much difference having a passenger made nor my full tank of gas.
We will hook up soon for some 1st gear pulls and see what happens.

Off-Topic: A 97ish Mustang GT tried to run me yesterday and I spanked his azz. It
was so funny...he tried again at the next redlight to take me...I just walked him. Not sure about mods, but he had flow masters...And He thought I was just another
slow rice boy in a yellow car...he soon fell in behind me and proceeded for the highway not bothering me anymore

Black R, your dyno numbers with the Toda Package seem kinda low. I don't mean to criticize, I'm just curious as to what your settings are? I know that Todas don't make a lot of peak hp, but I expected a bit more. Do you have any baseline runs with your ITR before the Todas? The reason I mention this is because I had a relatively stock but balanced Type R motor (I/H/E w/cam gears) in my 92 Integra GS and pulled 177.8whp (stock ITR cams with a 4400rpm VTEC crossover).



I was thinking the Toda Package with the Toda Header would at least get you to the 185whp mark. Since that dyno day, I've put in the Toda Bs, Toda valve springs, Portflow headwork, JDM ITR pistons, Test pipe, RC 270cc injectors, and a BBK fuel pump. I must say that I'm looking for over 200whp. But I suppose I have to wait till I hit the dyno again to say for sure. I was able to hit a 13.8 @ 101mph at the track with slicks and full interior (1.997 60' and car weighed in at 2850 with me in it). So I feel I'm about at the 200whp mark. Again, a HUGE speculation on my part, but time will tell.

Anyway, I hope you break your goal of the 200whp mark. I just really thought you would be closer than you are with what you have. Best of luck.

I believe BlackR's todas arent dynoed tuned yet. They are just in there set at 0.

Dan: yeah I love killing Mustangs as well. The story goes: I was pulling out of the bank and he served and rev'ed hard. So I got right behind him at the redlight. Light tunred green and he floored it, I did the same. As soon as I cleared the other car in the other lane I got over..I hit 2nd gear, spun a bit, then proceeded to pass him, into 3rd I just pulled harder...I shut it down about mid 4th gear...He just looked amazed that he couldnt do anything with me Little did he know my lil 4 banger revs quick!

gah! I didn't want to get into a debate on why I'm making relatively little whp with the spec b's...

Let's just say UNTUNED I'm making 175 whp. Conservative? Yes. Very rich? Yes. Safe? Yes.

Yes, I'm expecting 185+ once I get it tuned but I have the stock exhaust - which feels like a bottleneck according to my butt-dyno.

For more info on my setup, just do a search for topics posted by me and you'll get the whole story.

Bah... I call rice on this one.

I saw it all the way... those fools couldn't pull away from me in my stock ITR. j/k

I definitely think Ken will whoop *** once he gets the car tuned. I think it was more of a same HP (~175HP) ITR's with and without JDM f.d. battling it out.

This was coming back from SpeedVision/Road Atlanta race. The funny thing was that if we were to combine the parts from 3 ITR, we'd have a "race" car. The lone PY ITR in the Touring series only make 175HP at the wheel... food for a thought.

Hey TJ Blank cleaned out my throttle body and clean off the screw that goes into the throttle body and the car still idles like crap but it pulls harder now and I don't really feel that loss in mid range like I used to. I'm waiting on Kenji to chip my P28 ECU and send it back to me. When I get it back we should run again.

Ken car sounds like it'll be a monster. When you go to get it tuned let me know (Don't take it to [un]Reliable. I haven't seen them tune a Honda and get good results yet).

Hey Ken I'm trying to get everyone to the track in a weeks time (Saturday hopefully nothing going on). Wanna come? Same thing to you Cosworth. You're welcome to join. We're trying to get down to Reynolds.

Can I share in the good times to about Mustang Kills. I was driving to co-workers home after work one day and this newer 2001 Mustang is junping thru traffic to line up with me. There was too much traffic though so we just played with each a little. I decide to take the long way home to see if I can line up with this guy. Truth be told I expected to get my *** handed to me. We finally get a light and I decide to strike up conversation. He tells me he has flow masters and a different rear end (Don't know which one).

Light goes green and we take off. We both get wheel spin and I instantly get a half car length on him. We shift into second and he comes charging back and puts a bumper on me. 3rd gear i put a bumper on him, 4th we stayed with me a bumper ahead of him (Maybe half a car length).

I was impressed (Given a full tank of gas, 2 extra bodies and and the car wasn't runing great (Until Blank touched it). He was impressed as well he gave me a thumbs up and turned left.

well since this has turned into Rustang kills. I got one. Coming back to work from lunch Monday, a 88-93cutsoff people to line up with me. I am sitting there ignoring him listening to this new jazz cd i just bought. He is revving like we were at the Gatornationals. The light turns green and i let him have it. First gear he's still there, second gear start the wave, third pulled a half a car on him,then took him in the rest of the way:D

TJ,

How hard is it to install the JDM final drive?
This is an abbreviated list of what you have to do. You can decide if that is difficult or not.

1 - Take off the intake system
2 - Pull the drive shafts out
3 - Remove the tranny (drain it first )
4 - Move over to a workbench and pull the tranny cover off
5 - Pull the primary and counter shafts out
6 - Tear down the counter shaft and put all the pieces back on the new counter shaft. Use the new first gear and bearings that come with the kit
7 - Remove the ring gear from the diff and install the new one
8 - put it all back together!

Unless you have done worked on your car before and have the right equipment I would not attempt this. It would take a quick mechanic several hours to do the job. I plan on doing it over a few days in my garage once the parts all come in. I have the tools, the shop manual and have studied the procedure in detail for many weeks. I'm also going to have some experienced eyes watching over me while I tear down the tranny. I would consider this a difficult job but that's just me.

Regards,

Hey Apexi GSR, I saw your sig and have a few questions:

How does the ITR tranny treat you?
Is it that much of a diff going thru the gears?
Better acceleration than the GSR tranny?
Do you have a LSD also?
