opinions on setup

[jmdst28]

about to start ugrading my 96' gst spyder. have been doing a lot of reading and have decided to go with the EVO 3 16g turbo as well as the mani and o2 housing. in the process of removing my ecu and sending it to ECMtuning to get it EPROM w/ ECMLink. thinkin on running a 255 walbro with Fuellab AFPR and 650 injectors. would it be a good idea to do a fuel rail while im doing the rest of this stuff now or is it not needed yet? i have no engine work done to this point could i be setting myself up for catistropic failure? Any input is encouraged

For your set up the stock fuel rail is more than good enough. There is no need at all.

And what exactly are you thinking would cause so much failure? I would say a good 60% of people are running an identical setup to your goals.

 

[cookmeup272]

Do you have plans of going bigger in the future? You wouldnt even need that 255 for a 16g, although having it wont hurt.

 

[jmdst28]

car has 107,000 on it i plan on havin it for a while as it has been family owned since 96' i just dont wanna have to rebuilt top/bottom end i take it to the track weekly as it is. as far as going bigger goes i havent decided that yet.

eventually i would like to cam it and do rods and pistons but that will be father down the line. would this setup still be worth doing if those mods are in the future? i dont wanna spend the money only to have to upgrade again later on

awesome setup im running something very similar but with a 2.4! Awesome little street car, gets me to work and school, starts up on a time, and takes off when you womp on it as well. My setup is just about all im looking for out of the car, perhaps a 20g or equivalent to get me around 400whp soon but that would be it. I definitely recommend this setup to anyone, especially if you are just modding your car. You will be able to take down most cars on the street with this if need be

 

[GsXdSmKingGsX]

Your plans for now are fine. You shouldnt have any problems. Maybe a step bigger on the injectors just so you dont come close to maxing them out.

 

[jmdst28]

about what whp are you at if you know id like to reach 300+

and 660 injectors? what would you recommend?

 

[cookmeup272]

You could always go 750's to give yourself some extra room, but like I said before....you won't need them

 

[GsXdSmKingGsX]

about what whp are you at if you know id like to reach 300+

Well for 300+ then 750's or 880's. My friend runs a GSX that dynod at 258hp 236tq and he wishes he would have gone a step up because there isnt much room for improvement with the smaller injectors.

 

[cantgo2fast]

I went with 750s and wish I had gone to a 255 walbro as well, mostly because im going to E85 now. I think one more step up in injector size and the pump and you should be good to go. IIRC there isnt much of a price difference between 660s and 750s and if your going to get link you have a way to tune them properly.

 

[doayamaha]

A buddy of mine is running about the same setup with larger injectors, e85 and a front mount on stock bottom and top end just went 11.95 in the quarter and drove it to and from the track

 

[jmdst28]

think im gonna go 880 injectors just to have room for inprovement. thanks guys appreciate the help

 

[crash89]

Since your going to be running DSMlink, you might as well just get some 1000s. Theyre pretty good priced from Advanced Fuel Injection.

 

[jmdst28]

you thinkso ? i guess with link you cant over do it right?

 

[crash89]

Right! That way, in the future if you do decide to maybe go with a 20g setup or something of that nature you wont have to upgrade your injectors again. Why but them twice when you can get it right the first time!

 

[cookmeup272]

Not right...you can overdo it, you get to a point to where you suffer major driveability loss if you go too high without something like an easy tune box or whatever. But you will be fine.

 

[jmdst28]

so id be good with the 1000cc injectors i wont go any higher than that so its down to 880's or 1000's

 

[gofer]

Get 1000cc injectors if your running link. All of the above information is 100% correct but you won't have driveability issues on 1000's and V3, the new software is just too good! After all, once you get all the above parts installed you might do some research and find that E85 is something you'd be interesting in running and those 1000cc injectors would be perfect for it and that Evo III 16g.

 

[Imback]

I would go with the 1000's so you have more then enough of injector for the evo3 on either pump gas or e85 if you ever decide to go that route further down the road. Also i would skip the evo3 o2 housing as it will require modification to your downpipe as the angle of the flange is different. As for the pump if you plan on just keeping it on pump gas you can save your self some money by just getting a fuel pump out of an evo9 and using your stock FPR. A rewired evo9FP flow's around 210LPH if i remember correctly. And it will not over run the regulator. I ran a similar set up to what you want to do and i was fine on stock internals i was pushing 23-24 pounds daily with no problem.

My personal opinion has always been to know where you want to end...not just in the short term but also in the long term. I always buy the new top and bottom for the engine and sit on that stuff until I can afford the bolt ons (dont want to wear stuff out before the project gets exciting) I've probably got close to 12 or 13k invested in my engine alone at this point...and I'm super happy I didnt screw around making middle of the road upgrades to bolt ons along the way...if I had that price tag would probably be closer to 16-17k to get her where she is today.

PS yes the eclipse is a new build...no it's not my first rodeo

Yeah...I've heard more than a couple of people remark on the durability of the stock 4g63 internals...some say they'll hold up to almost 600hp...which reminds me of another story I read along the way...I ran into a guy who was doing a frankenstein job that sounded kinda promising...he said he was using the 7 bolt pistons, 6 bolt rods, 6 bolt block, 7 bolt head...something about the 1g rods being stronger and the 2g pistons being stronger...and something about the 2g head flowing more air...and of course the 1g 6 bolt crank and block to avoid the walk / crank position sensor damage...just remember to take your balance shaft out...#1 killer of our cars

This will give you an idea on injector size

have an Apexi N1 what modifications would i be looking at?

The difference between the outlet flanges is about 3* where the downpipe bolts up, just use the below pictures to compare the difference. The Evo III o2 housing is the on the left OR furthest away depending on which picture your looking at. The 3* difference isn't much so its still possible to get a slotted flange downpipe to conform to fit up to the Evo o2 housing. The problem is it puts un-necessary "flex" on the flex section of the downpipe and will cause more problems down the road. If your dead set on running that o2 housing you must change downpipes for one thats FOR the Evo III housing.
