Hi guys,

got my car tuned to 233.5kw@4wheels (read my sig for the list of mods i did to the car. Now if i were to upgrade the stock STD turbos to 2530s wat do i need to upgrade to support the turbos? I have read the sticky thread on the Rb26 turbo upgrade and i read a few guys did it. But in the list the didnt specify which fuel pump they use and fuel pressure regulator and injectors.

So is it safe to say i need to upgrade the injectors(800cc), fuel pressure regulator and a 044 fuel pump? Apart upgrading the clutch (to jim berry specs) what else do i need? THanks for the opinions guys.

P/s : My aim is to get 300kw@wheels.

I'd be chatting to the bloke who tuned your car :3some:

Very wise man.

It depends on what turbos you purchase for the most part as you might need injectors/afms, you might not.

Yea but i want to have some sort of idea first before i speak to him and weigh out my options first(budget wise!!). On the stick thread turbo upgrade people who used 2530s turbos uprgraded the injectors but not the fuel pump (accidentally left out of typing?).

Well depends what power your after

300-320rwkw or 350rwkw really.

If its a street car i'd stick to the 300rwkw and go for a GT-SS (or similar) package as its the most responsive.

Then you wouldnt need injectors/AFM's with a bit of luck.

But then if you went 2530's you need a bit more gear, but you would get more power for the added expenditure :3some:

you mean if i use the GTSS turbos i dont need to upgrade the fuel inectors and the AFM? My aim is to achieve 300kw@wheels.

I sure am :3some:

Ben will give you more detail, ferni's car is setup like that and going well so far i believe

ohh ok if thats the case GTSS is a cheaper option for me then. This is what im thinking, since i will b doing mostly city and hwy driving i dont need a big turbos. Meaning i want to have full boost at 3rd gear will the GTSS turbos suit this application?

Will ask Ben when i get back into the country.

hmmm since you said youre on a tight budget then it makes things hard

pushing 300 at the wheels is going to test a 17yo fuel system. In good condition it will handle it but if youve got gunk filled injectors then who knows

For peace of mind and insurance id at least change fuel pumps. Try being on a tight budget and trying to rebuild an engine....it just doesnt happen. Outlay some insurance now. Its not as if a bosch 044 will cost you an arm and a leg.

The internals will be fine as long as theyre in good health. Get a compression test and leakdown down before the turbo change. It may just give you some foresight to take it easy before you damage anything or may give you some confidence in the GT-SS or 2530 route

will take into consideration. It make sense as well for the fuel system. I think the pump is about betweeb2-300bucks as apposed to the injectors which is about 800bucks.

      I would hope so. I worry that it also might depend on whether the person working on the claim has had a good day or not. I could imagine that for example modified brakes would be an easy thing to point to for affecting the outcome of an accident. I don't know. I will keep paying my premium and hope for the best. But at the same time keep safe distances, drive defensively and avoid dickhead P-platers in lifted utes

      I was just working on the assumption that a cammed V8 is significantly less polluty than a Japanese I6 turbo was at the way they tested it in an IM240. Perhaps I'm wrong! Perhaps cutting one of the readings I got in half is a tall order. I don't know too many people who actually got their cars emission tested with a RB to really compare the data.

      I thought it was just if “the modification effected/caused the incident”

      Ok, good to know. I have open loop I think, I forgot which ones which but I am running the o2 sensor, brand new and I got a new boost solenoid because my last one was faulty and overboosting by a lot, but it's still technically overboosting. Haven't really bothered to hunt it down as I don't send it hard regularly.

      You should not be able to see much smoke behind you if the mixtures are good - for ~13-14 psi anyway. It's not like you need to be running hell rich for only that much boost/load. Your tune might be a tad too rich. The tuner might have done that because they like to run a lot of timing. It's impossible to know what's going on from here. It won't be the actuator. It won't be the MAP sensor. Regardless of if by "MAP sensor" you mean either the Neo ECU's boost sensor (which is literally only that, a boost sensor so that the ECU knows a) that it's achieving boost, and b) that it is not overboosting) or you mean the dash gauge's MAP sensor (because it can't have any effect at all), or you mean the boost controller's MAP sensor (because it is very unlikely that it is running in closed loop, and so it is effectively just used to know when the pressure goes positive and so you can see the boost on the display, for the most part).
