Well I'm at a situation where i probably leave the FI Scene and was thinking of the 98-01 spec ITR JDM Motor w/4.7FD N/A

I would like to ask those who have own or personally driven these motors a few Q's?

#1) Compression Cylinder Tests Difference from the two motors?
#2) How are the 4.7FD for Daily Driving?
#3) Overall is it worth the $4K +mods (in the future)?

*Please Indicate notes: If any mods. have been touch ex: Headgasket, milled, OS Pistons ect.

 

The 4.7 isn't too bad for DDing...

 

Try an ATS 5.077FD with M-Factory close gearing... It'll be fun topping out at 110mph.

Yes, 4.785FD is fine for daily driving from what I've been told.

 

If anyone knows:
What is the Max speed for the 4.7FD & the 4.4FD?

4.400FD = 154mph

4.785FD = 142mph

4.928FD = 137mph

4.400FD with M-Factory 3rd (1.695), 4th (1.296), 5th (1.000) = 131mph.

... Yeah, I haven't been researching final drives/gearing lately.

Crazy bastard.

 

You generally want less of a FD with more power knucklehead...

 

Well I'm only shooting for 200-215whp, so 4.928FD would be great for my setup. Parts have to work together.

 

thats were im at right now. got the ats 4.9 final and it feels like its on crack. got the acceleration but i fill up every 3 days now with my type of driving..but loving it.. ..i max out my 4th gear and it was a little over 110 mph. i dont know if it will really hit over 135 at 5th.

 

im under 4k and under the speed limit with OEM JDM ITR trans. i dont remmber but i think 100km is like 37 3800?
i loveeee my JDM R swap.
i have driven a few of my friends USDM R's with USDM motors and maybe the ones they have are just tired or mine is extra quick but...

also its worth considering to have a b18c5 in the engine bay instead of a b18c. depending on what your going for...

 

im about 285 comp on all 4.
and #3) where you put your money.... its up to you if its worth it. IMO

 

Would you guys invest in this motor or FI?

JDM y0!

 

******* winds me up when people call it a 4.7 final drive


if you're going to bother rounding it, last time i checked 4.785 was closer to 4.8 than 4.7. fucksake.


70mph is 3,900rpm. perfectly liveable

don't lie. even when my car was stock i smashed 150mph in 5th, with more rpm's to go. the speedo isn't THAT innaccurate

 

i jus drove my whip, 100km was 36-37 right in the middle. and 110 is 3900.... thats very drivable.
i say go for the NA! if you want to go for the max power quest... sell the R and use the extra money and decreased attention to fund a really fast fmic'd out GSR or LS or RS.
thats what i would do... i love NA but if i had something like an SI or something, id imagine snails would sound pretty good...

Annnnnd do you just have the final drive, or a '98+ Spec transmission?

 

How much would it cost to have a 4.785 final drive put in? Is it a DIY project? This is a mod I was contemplating on getting in the future

Are you mechanically inclinded? Do you feel comfortable with a lot of moving parts?

My first transmsision that I rebuilt took me a while, but I acomplished it. You'll feel proud that you did it all yourself.

hahahahhaa. it could be a diy. and you have to be pretty damn mechanically inclined. i plan to go 4.9 fd in jan or feb.. cant wait

 

I myself, I'd rather pay a professional to do something like transmission work. Hell, I just pay to have everything done on my Type-R, other cars I enjoy working on, but with this car, I'd rather just know it's done right.

With that being said, if you know what you're doing, give it a shot. I'd rather have it done by someone who knows what they're doing.

'98 spec 'mission


as the dudes talking about a JDM motor or a USDM motor, i figure he's talking about getting a tranny with the engine, so it wouldn't be just the final drive anyway

yea

True but 98 Spec JDM ITR transmission have a 4th and 5th GSR gears. So obviously if you put a JDM 4.78 final drive into a US tranmission (or a JDM 97-97) it will be more aggresive in 4th and 5th.

 

I have the 96 spec ITR motor totally felt a difference over the US ITR. I think it is worth it, all I have on my motor is intake, exhaust, and flywheel and it moves pretty good but it is a personal choice so its up to you.

That's funny... Because the '96 Type-R is more similar to the USDM Type-R.
