I have pretty well decided to rip out my 7 Bolt before I ever get crankwalk and looking at a 2.4L Stroke 6 Bolt 4G64 Block - Wiseco Pistons and Manley Rods, with my original 2G Head which will be ported and has 264 / 272. I currently have a SBR GT12, 660cc Densos, Walbro 255L HP, B&M FPR, DSM Link V2 plus supporting mods. The fuel over here is less than 90 Octane and an looking at a larger turbo to use the full potential of the engine. I am either looking at
1. Staying with the SBR GT12
2. SBR GT14
3. GT35R
4. FP3065

Any advice on where to go? Also please note if I would have to upgrade injectors and to what.
 
Well, you're just going with a 2.4 block. There is nothing "stroker" about it.

I vote GT35R. Look for some 850's.

90 octane, ack!
 
you should check out the 800+hp evo in one of the magazines recently (super street?), they make huge power with better fuel, and mediocre power (considering the car's capabilities) on decent fuel.
i wouldn't expect to run much boost with that muddy water for fuel there...
 
Well I run a 60-1 on my 2.3L and love it, I know a guy who has the 3052 on his 2.4L and he couldn't be happier, his is daily driven, and off throttle response is great. I think that the 3065 would be great for big power. I get 20psi by 3500rpm with my turbo, so with the 3065 it should be the same, if not better, with the added displacement and headwork/cams. I'm not sure if this answers your question, all I can do is give you some insight. On a side note, with the 2.3L and a 60-1 turbo Gritsak ran an 11.3 @125 on 21psi.
 
Chris, any comments and help is much appreciated especially when I am about to sink another $6000 minimum, not including the turbo, into my car. Everybody says you must have a goal. That was what I thought before I bought the car. Goals should always changes as you aim higher. My first goal was the Big 16G until I outlived it. Then the GT30 56 trim. Now 2.4L and a bigger ???? turbo. Goals are meant to be modified. Just like our cars.
 
g4cs 2.4L SBR gt-40

i will let you know monday.
 
What kind of power do you want? How much lag are you willing to take? Some people think my turbo is overly laggy, but I am fine with it. All those turbos will spool decently fine before 5k rpms on a 2.4. Are you going to get a sheetmetal intake manifold and how high are you willing to rev it?
 
I am having the same problem, these are the turbos I am stuck between:

-GT35R TO4S with a .68 T4 exhaust housing from AMS
-FP3065
-FP3575

I have tried emailing FP to find out more about the 3575 but have yet to get an email back from them.

Then fawk them, they don't want to answer customer questions, Customer is going to have to purchase a competitors turbo ,and thats the bottom line :p

Are you going to be running a T3, T4, or a mitsu flanged manifold. That alone should help you choose your turbo out of your list of turbos.

Call them up. They will talk to you. A phone call is easier to get information from than an email as many shops are busy and might have to catch up answering questions via email.

If you've noticed how FP named some of their other turbos, you might be able to figure out what the 3575 and 3775 are. FP 3065 = gt 30 exhaust wheel, 61mm compressor that flows 65 lb/min. That should be enough information to figure it out; if you still can't, you can PM me if you want.
 
i had the same question so i called fp and they said go with fp3052 with pump gas (91-93octane) youll probably hit 25psi at 3200rpm and the the fp3065 will prolly spool 28-34psi at 4200+ soo unless your racing everyday or only raceing, go with the fp3052 just my mine and fp's .02cents
 
I would do either a GT40 56trim mated to a ptrim turbine in a .59 or .70a/r on center, T4 housing.

Or, a T67(TO4R) mated to a Ptrim turbine in a .59 or .70a/r housing.

These two wheels are perfect for a 4G64. Although, keep in mind that they are 10lbs per min apart. The GT40 flows 65lbs. The T67 flows 75lbs.
 
I would honestly call the vendors themselves: agp, fp or slowboy.

See what they say about trim size etc..
They'll probably have more questions for you than answers, like what rpm you're going to run, hp expectations, type of track use/street use.


I'm looking at different turbo combinations myself. All my friends have their opinions, but calls to the different vendors have shed new light for on the subject.

If you start to hear repeated opinions, you've got your turbo.

Ive had nice results with my gt40 compressor but I do wish I had gone T4. You will find the 2.4 REALLY wants to breathe and the more you can do to help that out the bettr.
 
go with the gt35r for sure, with the to4s cover and a .82 a/r. id also go with ams custom gt35r that they have made. its just alittle bit diffrent but its worth the extra 100 dollars. this turbo is alsome ive seen cars with 2.3 setups trap all day in the 130's.

eric the white 1g from ams put down over 550whp at only 26psi if im not mistaking with there gt35r. his car is daily driven also and traps all day in the 130's. id give ams, agp, sbr, br, or some other known shop a call and ask for more details.



as far as any other turbo out that that makes great power is the fp3065 this turbo is nuts for a bolt on. its pretty much a bolt on gt30r but seems to work alot better, it seems to put down better time's then even the gt35r. its a huge decision if your looking at these two turbos and im sure you would be happy with either one.

Um, the 3065 and the GT35R are almost the same turbo just fyi and times don't tell you much about a turbo as cars can have very different setups or weigh alot less than yours. Both the 3065 and the GT35R have the same 61mm 56 trim compressor wheel. Pretty much if you have a T3 flanged manifold, get a variant of the GT35R. You can get a turbo like the PTE GT3561 which is pretty much a GT35R minus the "R" (ball bearing) and costs $500 less. If you have a mitsu flanged manifold, you have the choices of the FP 3065, and any other turbo available as a bolt on as there are many companies making bolt on 61mm turbos (PTE sc61, 3561, SBR turbos, etc..).

ok buddy :thumb:

if my eye's serve me right on fp site it says it uses a gt30 wheel, witch makes it a bolt on gt30r mixed with a gt35r aka 56trim wheel.


That's not what you said before "buddy".

Guys, thanks for all the info. It seems taht many or you think, I should be looking at a FP3065 or a GT35R. I am looking to bolt up to the ported EVO3 exhaust manifold. I will also port my 2G head as I have spend the money on a RRE Extrude Honed Intake manifold which is sweet. I also have a TRE AWD spec tranny on a FWD car, which has no problems with the higher revs. It also has the GVR4 Shaft with a 25% taller 5th gear. I am currently running a SBR GT12 - GT30 56 trim. An initial option is to run this turbo on the new engine and upgrade within the first six months, just to work out if the turbo is actually too small. Any comments would be highly appreciated.
 
Just thought I'd add my 2 cents-

I recently ordered the full GT30 BB kit from AGP with the 65lb/min (56trim) comp wheel.
I researched the 3065 and GT35R and found the 3065 to be about 500 more for a similar setup and the 3065 to be even more than that. All of these turbo are rated at 600-650hp. If your looking for a simpler, cheaper option, consider the AGP kit :thumb:
BTW, I'm on 2.0L and still happy so I wouldn't be that concered with lag in regards to any of your choices on a 2.4
