New Turbo. Suggestions.

[Mattgr]

Hi guys, i will be getting a new Turbo to replace the stock one in my rb25, i have been looking at a GT3037, anyone have one/ used one, Whats your opinion + Suggestions for other turbos are more than welcome. Cheers

[34GeeTeeTee]

Matt..... Your going to get flamed for this!

There is a new thread everyday for the same thing.... There are links to turbo threads, links to dyno threads and MORE information that you could ever ask for on here.....

I am not being a smartass, but the guys on here seem to get annoyed seeing the same threads ALL the time....

3037 is an awesome turbo, you need to consider all of the supporting mods to make it work....

Get reading!!

[Mattgr]

Yeah ive looked through many threads, which is how i came to the conclusion of getting a 3037. I dont know which mods i need to make it work, so far this is what ive come to, HT055001 ECU, 840cc injectors and a 040 bosch fuel pump. Am i able to upgrade to this turbo before i upgrade my ecu or should i do them all at the same time (will probably be a few months apart as i try to make up the money to buy these mods)

[Piggaz]

Do it all in one go unless you like tuning your car for the sake of it.

[75coupe]

do all upgrades at the same time, then get tuned.

dont run that turbo on the std ecu, not worth the problems it may cause...

have you thought of boost control?

what wastegate?

Why a 3037?

Running E85 or 98?

with that turbo I would be thinking you want to rebuild your engine, if its still internally std, in the next year or so?

have you done suspension & brake upgrades?

and include a new clutch in the your list of parts to buy, as well as new pivot and new tyres...

[34GeeTeeTee]

To back up the stuff above, the turbo only cost me $1500 new (i see one if the FS section now) but to fit that to the car the way i wanted and get it tuned you times that by 10....

There is a modification guide on here somewhere too, search for that as it tells you the stages and then you can work out your goals!

Boost control, power fc?

i dont know what a wastegate is, ill do some research on that one.

3037 because ive heard good things about it, can you suggest anything better in the same price range?

running 98

Why would i have to rebuild my engine? Which parts?

ive upgraded suspension, brakes, clutch and tyres already.

Dont know what a pivot is either.

[75coupe]

you already have a PFC and boost control kit? if not consider a different ecu for future proofing

I would expect most 3037 users would go an external wastegate setup... yep learn about wastegates for sure...

consider flex fuel setup now or atleast keep it in mind for later down the track...

because a 3037 will make a truck load of power for a std engine... that will be a matter of opinion and you'll get lots of opinions...

what tyres?

new clutch will mean a stronger clutch pivot, $60 for a nismo item, its stronger... then your pedal bracket may break, so perhaps weld it up first, depending on your clutch choice...

[75coupe]

hmmm turbos in same price range...

3071, 3076, 2835proS (had to put that one in)....

then look at the kando and possibly hypergear threads for cheaper alternatives

So the haltech HT055001 isnt compatible with PFC and boost control? If so, which one should i be going for that is? Also, i have an apexi actuator valve controller in my glove-box, not sure if that's the same thing.

What's a flex fuel setup?

Some Kuhmo tyres which were $215 each, not sure which model

The guy i bought my car off had less knowledge than i do about it, he told me the old owner put in a heavy duty clutch, but i have my doubts, it doesnt feel like a heavy duty one to me.

[75coupe]

you can ask for options but really you'll just one persons opinion of many peoples opinions and then be left confused or going off what someone thinks is best... it could in fact be wrong for you..

the haltech you mention is a plug in ECU yeah... the PowerFC is complete ECU and you mentioned the boost control kit as boost controller...

you dont want to be using two ECUs...??

flex fuel means you can use 98 and E85 in the same fuel tank and the ECU can trim fuel to compensate for the ethanol content changing... search SAU for flex fuel, you have much to learn...

I mention tyres cause you'll end up buying lots of them and decent tyres will actually hold the power alot better than crap ones...

start reading...

[75coupe]

list your current mods, with details, like models, brands etc...

[Mattgr]

So PFC is an ECU, sorry i thought it was a boost controller. so confused..

E80 afm

3-3.5" exhaust

unknown brand coilovers.

Atmosphere BOV

Im heading off to work now so i wont be able to reply for a few hours.

[75coupe]

whats an E80 afm??

your exhaust changes from 3 to 3.5"???

ok, I said enough you need to learn what it is people are suggesting otherwise I could suggest you need to install a WMI kit for brake cooling and install a hicas lock bar to reduce turbo lag

[Mitcho_7]

If you want to skimp on cost, get a z32 ecu and put a nistune board in it and then get a profec b boost controller or something similar. Should cost about $850 or so.

If you can get a 3037 or 2835 pro s by all means do it, neither will dissapoint you but they are a little harder to come by these days. A gt3076r or gt3071 will be good options as well or look at the hypergear range such as an ss1pu or the G3/2.5. You need to decide if you want to run internal or external gate though. Seeing as you seem like your are new to everything i think you would be best served going internal gate and if you want the turbo to bolt up to the stock exhaust pipe then a hypergear will suit you. You can get gt3076 turbos with the nissan 6 bolt dump pattern but they apparently arent the greatest.

On top of the turbo and ecu the other things you will need:

3"+ metal intake pipe

Front mount intercooler

3"+ turbo back exhaust

555cc+ injectors (if e85 you will need bigger)

Upgraded fuel pump (nismo/tomei and bosch are good)

Z32 air flow meter

A clutch capable of holding around 300kw

Set aside $$ for the possibility of new coilpacks as well

Im sure there are probably other things you will need as well, but thats all i can think of off the top of my head.

I recommend you do a lot of reading and searching through threads in this section as all the info you need is here

problem is he wont understand what you just wrote...

Gives him something to go read about!

[75coupe]

Yeah ive looked through many threads

obviously not enough

[Mitcho_7]

problem is he wont understand what you just wrote...

It can be there for reference when he has done some research then i guess.

OP, I think part of choosing a turbo comes down to how much power you want and what you are going to use the car for. If its a purely street driven car then the response is probably going to be more important because its nice having 300rwkw but how often will you be at 6500+rpm in 4th gear on the street to make use of all that power? Having said that, 300kw at your disposal would be boss haha!

The turbo choices I listed were just going off of the 3037 size that you mentioned you were interested in.

[ARTZ]

I love this guy, makes a thread to ask our opinions on which turbo is right for him..

So we all give our opinion that he should mod other things before worrying about a turbo.

A week later he wants a 3037

Next week it will be NOS, 2 of the big ones. We will tell him NOS is for amateurs but he won't listen and then he won't listen when his laptop tells him "DANGER TO MANIFOLD", he will blow the welds on his intake and fry his piston rings cause he was granny shifting and not double clutching when he should..

Anyway we all know the story, base line is..Mia I'm a cop. ..
