Modifying An R33 Gts-t

[quiksta]

Nice thread and dont worry, us auto boys have just as much fun as the manual guys! The only difference is we have a left hand to do what we please... be it eating a burger or fondling your girl's tits! :sorcerer:

Amen to that.

Theres nothing wrong with an auto skyline. I think if half these manual drivers actually been in one they would change their opinions.

have been in 1. would much rather my manual one, unless i had big power, then i'd go auto (save frying clutches).

well for starters the ecu won't let you go above 180. secondly, no it won't break. it will just keep winding around.

Ah, okay. Then i'll have fun seeing it go round ^_^ I'm planning to fit in the hks speed limit defender to remove the 180 cap.

Auto's sweet! But i hate the way it wastes fuel and the strong engine brake, so maybe i'll put in a 5-gear auto transmission if i'm feeling rich enough, which is probably never

Just too bad that there aren't any aftermarket "plug-and-play" ecus for autos around... was reading how some guys try to fit an ecu to suit an auto car, and it looks seriously complicated.

Will I be breaking any QLD or VIC regulations (which includes making the car not roadworthy) if i fit in any of the listed mods?

For quick reference, they are:

1) Upgrading of intake: Apex'i Power Intake Kit.

2) Manual Boost controller.

3) HKS Speed Limit Defencer.

4) Replacing the intercooler with one from a R34 GT-T.

5) Changing the suspensions.

6) Spitfire coil packs.

7) Full turbo back x-force kit.

8) Changing of spark plugs.

9) Apex'i AFC Neo and SITC.

I'm pretty sure #5 and #11 are safe, but how about the rest? Anyone from QLD or VIC with the knowledge? I can't seem to find any guidelines or regulations regarding mods...

How mate the site in me sig may help you out a bit to

1) costs a fair bit for pretty much no gain at all (the often quoted jap review dyno was clearly done bonnet 'up'. You actually lose power if you don't spend even more money on a heat shield. I'd say leave that one for a little while.

2) yep. why not.

4) HKS speed thing'o , no need to do it yet and I'd just cut the ecu wire 53 from memory (do a search)

5) Yeah a good little mod. The core is a little bigger. Remove the panel in the wheel well behind the intercooler too for better airflow and make sure the ducting to the front of the little intercooler is there still. Bigger intercoolers on stock turbo's is a waste of money and more often than not your car will be slower.

6) For a start chuck some pineapples in the rear diff cradle. $100 better squat for better traction

7) unless yours are stuffed no need to get them, they are a nill gain on the stockish engine.

8) exhaust is a good move.

11) BPR6ES or BPR6ES-11's gapped down to 0.8mm

12) S-AFC II good little stepping stone.

Also consider a shift kit for the auto I think there is a group buy on them, perhaps a mild high stall as well.

All things being equal you ought to be able to get an auto R33 down the 1/4 mile a tad faster than the manual with shift kit and a stall in place.

Thanks rev210 and Munna1! Munna1, i've came across your site, and that's where i got the idea of replacing the intercooler with the R34 GT-T's! Great site!

There's a shift kit!?! I'll die to fit one on my car! *drools*

5) Yea, i was thinking of doing that. But... i'll be damaging the car, won't i?

6) I'm pretty new to this.. what do you mean by pineapples..?

7) Really? They cost a bomb too. Maybe i'll just throw them out from the list...

11) I got a quote of $260 for some platinium spark plugs... should i go platinium or stick with copper?

12) Why is everyone on SAU promoting safc2 when the afc neo's out? Is there something wrong with the newer model? By the way, both are compatible with autos too, right?

I dont know where your going to be taking it over 180km/h regularly or at all, so I wouldnt bother spending money on that. Go the Exhaust - turbo back then Pod filter with a CAI box or even better a panel filter.

Nothing wrong with the neo safc it just really isnt much better than the safc2 and you will find that these are cheeper. The NEO has a few more rpm tuning points and thats about it I think.

Yea, i'm planning to go for the exhaust first. I don't think i'll go 180 often, but i don't like the idea of having a cap there... maybe its psychological. Even my friend's maxima could go up to 220...

Now i'm trying to decide between spending around $200 or to just cut a wire.

[mad082]

you won't be breaking any qld laws, but i'm not sure about vic laws. i know one of the southern states has a law that limits you to 1 intake mod. that means either cooler or filter.

as for a car being slower with a big front mount, that is a lie. i put a hybrid front mount cooler on my car and it goes noticably better. if you were just cruising along and punched it it picked up much better. sure it has to fill up more space with air, but a good cooler has less restriction, so once it has that space filled it will flow more air through.

shoebox, my car gets well over 430 KMs to a tank all the time... and i boot it as well.

city or highway? i get about 250k's to about 50L of spirited city driving.

and how many l's are you reffering to as a tank?

A mix of both city and high way, city 70%, high way 30%.

Car is stock and auto.

Thats from full needle up the top down to the last line of the empty in my tank, however the light never came up, so I presume it still has another 10 or so litres left. I dont like to push my car till totally dry.

[mad082]

Car is stock

ahhh, that says it all.

[shoebox]

I'm stuck.

1) Apparently, Apex'i doesn't manufacture SITCs anymore... Anyone knows of a good SITC?

2) I've heard various responses regarding the upgrading of coil packs... how much difference is there between the stock coilpacks and an aftermarket one (like spitfire)?

3) If i were to only perform these mods, is upgrading the R33 stock intercooler to an R34 GT-T one necessary? I'm concerned about the blazing hot summers here...

[mad082]

1. apexi haven't made the SITC for ages. just search on ebay.

2. coil packs won't make much of a difference unless your old ones are dead.

3. depends on what boost you are planning on running. it does get a bit hot in brissy in summer, so prbably don't go past about 9-10psi on the stock cooler.

[Munna1]

If you plan on keeping the stock turbo the SAFC will be all thats needed. Your tune would benifit more from a SITC but its not really criticle at this point.

I have the usual mods with SAFC and the cars great and has 195rwkw (manual)
