Rusty's SS-II progress thread, Many TRD goodies Options

[Rusty]

a recent picture





a recent delivery...

I came across a guy locally in NZ selling this, a new/unused TRD mechanical LSD, it at a good price, if I hadn't have come across this I would have gone for the S54-6D, but people here have started to figure out which have the lsd and has put the price up/ harder to find a good one, plus add in shipping cost etc

anyway pictures






It has the part number 41301-ST803, but I know the part number was updated to 41301-ST804. And incase your wondering the other TRD LSD box is from my brothers old supra.

[Tigawoods]

Awesome!!! Is that the cluth type? I literally forgot all the knowledge I had gathered about LSD only a couple months after I got mine haha

[JoshuaM]

LSD Awesomeness.... You need to stop Rusty... you're running the risk of making it ABSOLUTELY perfect beyond any reprimand

[Rusty]

thanks, pretty sure its clutch type, its not the easiest thing to have a look at the insides of.
the info sheet it came with is a bit tricky for me to understand aswell. And its a bit tricky searching info about it.



haha wont be going in anytime soon though, will go in when its time to replace the clutch.

[Tigawoods]

ah I got a closer look finally (rather than looking at it on my phone) It seems to be a clutch type for sure. Awesome it came in the original packaging too!

is the sheet all in japanese? haha

[Rusty]

what the guts look like, though my plates are blue

It's been awhile now since I've studied Japanese at high school, the kanji characters don't help...

there's a break-a-part diagram, which goes onto different options, which I'm guessing is to convert from 1.5way to 2 way - like it says on the trd website

Adding a photo of it now...

[Tigawoods]

the top stock picture makes it look to be a clutch type. the bottom paper that came with it seems to be a helical, or maybe it just omitted the clutch "plates" from the diagram

Recently purchased myself a polisher, give it a wash, clay, polish & wax over the last couple of days.

[SwissFerdi]

You did a nice job because for the first split second, I thought your garage door was bent.

Got back today to install the recently purchased ecu, Tom's TECS II ECU for ST202 3S-GE




Wasn't too difficult apart from the 2 nuts on the driver's side due to the foot rest.


old vs new




Started up first go, no codes or issues, gave it a few revs, sounds good. Booked in on Thursday for a dyno power run and air/ fuel ratio check to ensure its all safe, it should be pretty good/safe but just want that reassurance.

[SwissFerdi]

Interesting, so no actual driving yet huh...odd how differences exist between LHD and RHD chassis, the foot rest is toward the outside of the car on mine.

[Rusty]

Went for a little drive last night as I had to get gas anyway. Nothing over 1/2 throttle or over 4,500rpm, felt good


Dyno & A/F check today
Everything check out great.


What can I say nothing but responsive

It sounds a lot more aggressive when the ACIS switches over, very smooth idle.



A gain of 10 KW throughout the entire rev range.
so:
@ Wheels
123Kw = 165HP

@ Engine
141Kw= 189HP

my first dyno:
@ Wheels
107kW =145HP
@ Engine
133kW = 178HP

[kurt95gt]

That's a nice little gain for minimal effort

[Rusty]

A good comparison over all 3 dyno's. (Went to the same place each time)




here's some of the AF ratio info I got
idle:
CO 0.17%
LAMBDA 1.157
4th gear 50km/h cruise:
CO 0.86%
LAMBDA 1.006
4th gear 100km/h cruise:
CO 0.60%
LAMBDA 1.013
Full throttle:
CO 7.31%
LAMBDA 0.805
How does these figures compare to other peoples, as we don't do emission testing here in New Zealand.

[richee3]

Nice gains!

[onnaj]

These are really nice ouputs! About the same as the beams! Well done and what a nice ECU did you buy!

[Syaoran]

Get me one of those TRD LSDs

[BonzaiCelica]

nice dude!

might as well get hks header and decat to complete your tune for max hp! muhhaha (with bolt-ons)

[Rusty]

Cheers for the comments guys. I'm quite surprised how much smoother it is over the rev range, especially the low end driveability.

Ha TRD LSD's are very rare to come across especially the front ST205 TRD LSD

I'm sure it would be pretty close to that 170whp mark without the cat. But as you can see I'm quite happy with it. The joy's of the range of bolt on parts for the 3S-GE

If I find a beams st202 for sale locally I'm going to take it in for a dyno to compare. As there aren't very many dyno's of them on here and the ones on the net are all over the place.



I guess you guys will be expecting a video of some sorts?

[delusionz]

Nice, lambda looks good. Did they listen for knock? or able to record ignition timing? or not so much in the way of datalogging?

if that graph was of a higher resolution, such as a dynapack printout might be able to check for points where ignition has been pulled to give you an indication of any knock.

have you checked to see if your E1 and TE1 diagnostic still works the same? and also ACIS operation.

and now to make the very most of that ecu, you must make sure your injectors and fuel filter are clean as ignition will be running on-the-edge, each cyl must be guaranteed it's supply of fuel

and also your base timing, spark plugs, rotor, cap and all that must be in tip top shape
