on the right track?

[firemaninil]

I am curiouse if I am on the right track here. This is my first DSM build up. I have a 96 eclipse GST. So far; bored cylinders 30 out, forged rodes, shallow bowl pistons, balanced everything, oversized valves 1mm, flowed head and motor ports, titanium seats and springs, stage 2 cams, underdrive and light weight pullys, venom intake, pacesetter header, high flow cat and muffler, will have high flow downpipe too, injun cold air, dual stage boost control, greddy blow off and emanage ultimate, venom intake and oversized throttle body, and a few other things I can't think of right this second. My goal was 500 hp hopeing for 550 or better. Havent gotten the car back from machine shop yet. They have iliminated most of the emissions stuff, and a bunch of vacume stuff. They say there are alot of little bugs they have to work out. Last time I heard the car run it sounded like it was missing and wouldn't idle at all. They have also told me that there is a sensor that went bad I believe it was the throttle position sensor and due to that when they hit a certain point in the throttle the car would just loose everthing. I have spent alot of money and time in this car and hope I haven't made any faital mistakes yet. Anyone that has had expirience with what I have done please feel free to curse me if I screwed up or let me know what else I need to do or how close I should be to my goal. I have a 92 eclipse GS that I want to build up when this one is done so any knowledge would be helpfull. Thanks

How about a front mount intercooler, DSMlink or something to tune with, and a good clutch kit.

+1^^^

And... What kind of fuel system/turbo are you running?

 

[firemaninil]

95burgundyesi, The intercooler will be added I just can't afford the one I want yet, as for tuning capabilities the greddy emanage ultimate is fully tunable and logs everything.

1g_tsi_awd I am running the stock turbo. I am not planning on increasing the turbo I believe we can do what we are wanting to without putting and oversized turbo on it. we are boosting this turbo to around 12 to 14 lbs. Fuel system will eventually be changed I will be putting larger injectors, aem fuel rail, and a higher flow fuel pump.

The t25 in no way will hold 500HP not even 300HP. You have WAY to many mods to run the t25, you cannot, even with a bigger turbo run that much HP if you do not have the FMIC or the fuel from injectors, or a fuel pump. You need to do those 3 things FIRST before you even run this car anywhere near your goals. Anyone else?

The Pacesetter header and all of the pulleys can go because they are just going to cause problems. You are going to need a pump, injectors, AFPR, and a much larger turbo. Probably be better off going full Garrett but you can get like a FP3575 if you want to reach your goal. You are going to want to get a set of cams. And don't worry about builing the 92 GS. It will be a waste of time and you will be better off using it as a DD since your goal isn't going to be very streetable with the size turbo you need to reach your goal. Hopefully you have a good MLS headgasket and ARP's for it as well.

There is NO WAY a t-25 will get you where you want... You would be lucky to make 500whp on a eIII16g... Think about a 18g or 20g or a gt35r... Why go half way and turn around?

 

[Novablue454]

Im not sure you need an AEM fuel rail. I think the stock rail is capable of supporting that. But I could be wrong.

Is there any particular reason you want to use the stock turbo?

You are going to need a rewired 255lph fuel pump, a AFPR to make it work, and injectors at the minimum.

I really hope this was all built with APR bolts.

In the Tech/DIY section, top left on any screen, there is a upgrade path. I would run down that and do a check off of what you have and what you don't have. Its a great guide and a lot of forums don't have somehting like that. Use it!

Also, get a BOV because your 2g is leaky and doesn't hold much boost past stock even witha t-25

There is no way any of those turbo's you listed besides the GT35R would come close to 500whp. 20g MAYBE get close to the crank. 500 on an e316g with a 150 shot MAYBE.

Couple things first of that pacesetter exhaust mani is cheep, it will probably end up cracking on you. Tubular mani's aren't usually recommended for a DD for this vary reason. If you want to use it, atleast weld on some braces to support the turbo weight to try & help prevent cracking. Not alot of people use Greddy emanage & it probably will take alot of time to tune/get running properly. I'd recommend something more user friendly, that will still meet your goal such as DSMLink. For that pulley set, does that include a crank pulley? If so I wouldn't be using it, as it won't dampen engine vibrations. I would also be ading cams to your list & an upgraded fuel system, such as pump, injectors & an adjustable fuel pressure regulator.

For the turbo, you have no chance in making anywere's close to 500 whp with a T25 unless you plan on running about a 300+ shot of NOS. The T25 can barely keep up with stock boost. All the other mods you have done are a complete waste of money as the T25 cannnot take advantage of them. You need a much larger turbo. At 12-14 psi on the T25 you will be luckey if you make 250 whp & that doesn't matter how many supporting mods you have, as that turbo is just way to small. Are you looking for 500 whp on pump gas or race gas? On race gas, this isn't super hard to do with the proper sized turbo, on pump gas this will be much harder & water/meth injecton will really help you out. For turbo you are going to want a 50 trim as the minimum size & I would go larger. For boost there is no way your going to do it on 12-14 psi, just won't happen. Depending on the fuel expect 25+ psi to achieve these goals.

Well, the only one that wouldn't would be the 18g... I said the 16g wouldn't... 20g could mos def get to 500. There is a guy with a 16g around me at 420 awhp...

20g & 500 whp defently isn't a common combination. If you want to get close to that it better be the larger TD06 20g. As for the evoIII & making 420 awhp, sure it to can be done but as well, isn't the norm. Also 420 awhp is a long way off from 500 awhp.
