Hello,

after turbochareging my stock single cam ka, beating on it and blowing it up - i have decided to take the leap and buy a r33 gts-t. It seems most people on ths forum like AWD over RWD, not me :D I have some pretty basic questions to ask about what i can execpt from the car.

it will most likey be a 1993 gts-t rb25det with some light mods already done when i buy it. exhaust, intake (cone filter), coil overs. The kms should be +- 25 000 from 100 000 more than likey above 100 000 kms.

I have heard and read good things about the reliabilty of this car, is it true - are these usually reliable daily drivers? i drive pretty normal most of the time but i do plan on some autox and drag racing.

What common issues should i be aware of when looking at the cars, given the kilometers?

My ultimate goal for now will be around 300rwhp (223 rwkw). am I correct in saying this is achiveable with 91 octane, colder plugs, fmic, 10-12 psi, 3'' exhaust, pulling some timeing from the high load section of the ignition map and adding some fuel in high load section of the fuel maps?

One last thing, im 99% sure the rb25det has a knock sensor.... will the ecu dump into the knock map pretty quickly if it starts detionating? i ask because we only have 91 octane fuel where i live and it would be nice to know there is some security there. water/meth injection might be something i'll have to look into.

for now i just want a fun, reliable, daily driver. I can already see the type of money i will end up spending on mods though lol.

this should be easy i have an 93 s1 gts25t.

Firstly, yes they have a knock sensor, and yes the stock ecu will go to the det map pretty quick.

Ok with just the following i have ~200rwkw

pod filter, ecu, electronic boost controller at 12psi, and a 3 inch exhaust and hi-flow cat and split fire coils.

Common issues are just yr average, old plugs, old coils possibly thrashed black... get yr pressure/leak down tests sorted and be prepared to buy some replacement parts and she'll be right.

You're going to have to make a choice tho

with the factory ecu fuel cut will kick in before you hit that power level.

So you can either but a few little gadgets like a/f comp, fuel cut defender... piggy back adjusters basically.

OR

ditch the factory ecu (and hence the knock sensor triggered det maps) and go an after market ecu with a good tune.

Also you're gonna need a new turbo... you either need more airflow or more boost. the stock 25det turbo get grumpy past 12psi and might not last long. so i'd just bite the bullet and get something a little better or get the stockie high flowed.

So if you get

intake

exhaust

EBC

Turbo

FMIC

and either

a bunch of piggy back bits

OR

a new ecu

then yes you'll have your nice reliable ride. I wouldnt worry about methanol tho... alot of work for only 220rwkw

What about chipping the stock ecu? thats how i tuned my 240. is there something about this ecu that makes it more diffucult to chip? It would be good if i could go this route, i already have a chip burner and a wideband i can throw in the car.

i got pm from member and with your info + the good things i am reading about these cars. i am pretty well sold 100% on the r33 gts-t. im glad i came to my senses.... i was going to buy a fairlady TT for my daily in the summer. lol very bad idea based on the amount of expensive repairs they require frequently. I know some people will dissargee... but i can't realy find a negative review for the gts-t. the only bad thing im hearing is they are kind of heavy - thats fine with me. seems like a good platform for 300hp daily. O, and i have a .63/.48 T3 from the 240 that i can throw on, internally gated at 8psi. mabey i will get a holset turbo for it eventually. mods will start during the next canadian winter lol....

Thanks for the input. more is welcome

i dont know about just "chipping" the stock ecu, but i believe nistune do something very similar with a board that plugs into the stock ecu which will give you the same functionality.. plus some extra features. look it up and see if it fits the bill.

Yeah good choice avoiding the TT, if your referring to the old z33 then everytime you want to do anything you almost have to pull the engine out.

GTST's arent all that heavy, the power they make makes up for the weight pretty well and they handle quite nicely too, not what you'd call spritely, but its certainly an agile tourer.

Not too sure about that rating on that turbo, but it might do the job quite nicely. if not the only real problem with the stock turbo is the ceramic wheel. get it overhauled and your be cheering.

Pretty sure your 91 octane is different to our 91 octane. Ours is 91 RON, I think yours is MON + RON/2 or something similar. As long as you run it on the highest available octane rating, you should be ok.

    • If you take the top half of the intake off you can unbolt the flap off the shaft and leave the shaft in there blocking the hole. Then you can remove the little vacuum canister off from under the manifold and get a spare vacuum line to run to the ECU. I can take some photos of it later. Probably best to get the vacuum source to the ECU sorted first though. Mine all worked mint with the base map from the GTT an I've pretty much let the closed loop sort the fueling and took 1 degree out of the whole timing map.
    • This IS something you also have to configure in Haltech (or at least I did in the past when going from onboard-to-ECU map sensor and an external MAP sensor in haltech land).
    • I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.
    • You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?
    • Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
