400+hp build?

[1G Eclipse94928]

I was looking for some input on a build i'm considering, if there's anything critical i'm missing, etc.

Already have: Boost controller, 16g turbo, Exhaust manifold Exedy pro-kit (clutch, throw out bearing, etc.) just got new belts and pullies and waterpump 1,000miles ago.
My turbo is going to be at the limit, so i was thinking of getting a Precision Billet CEA 6266, but i haven't seen anyone run one on a dsm.

If you're dead set on 400hp you may want to go with a bigger turbo, or at least a different variant of the 16g, the FP68HTA maybe, or build your 16g into a 20g hybrid. With a multi-layer steel head gasket you will need to have the block and head resurfaced, is this something you had planned on doing? Are you planning on a pump gas tune? 93?

 

[99ECLIPSEGSXDSM]

Sounds like you still have a lot of reading to do. Check people's dyno slips that are around 400 to see what setup they are running.

Before you do this make sure your maintinance is up to date

Punishment Racing sells the same core with better piping for cheaper.

A nice upgrade, but not necessary. A healthy stock trans can handle your goal with a welded/4-Spider center diff and the right gear oil. If anything, get a stock rebuild and put the cash towards a good clutch such as South Bend.

8: ARP DSM HeadStuds + 4 Layer DSM Metal Headgasket
Head studs are good, but a composite head gasket would be a better choice. Like mentioned, MLS head gaskets require a very fine surface finish on both the head and block. Composite head gaskets can handle over 500hp with studs and a good tune. They can also help reduce damage to the engine by blowing out under extreme pressure.

My turbo is going to be at the limit, so i was thinking of getting a Precision Billet CEA 6266, but i haven't seen anyone run one on a dsm.

The 6266 is a bit overkill for 400hp. Even if you were looking for something in that size range, there are much better options out there such as Holset, Borg Warner, and Forced Performance. That's why Precision turbos aren't popular in the DSM community. Well, that and PTE Ball Bearing turbos can't be rebuilt. And some of them explode.

 

[DROPthatCLUTCH]

Your gonna wanna get a holset man. Can pick one up for under $500, I bet I'd you search holset in your local classifieds right now you'll see something. Hx40 just got sold around my area for $150. Also, read the holset threads and you'll realize YOU NEED ONE OF THESE TURBOS!

Good luck with your build bro!

Yea my mechanic is helping me he has a metal worker with a shop that works for the city. I realize my turbo probably wont hit 400hp but it will push 32lbs.. I wouldnt buy a fp68HTA, i would rather get the cea 6266 even though the spool would be slower. I'm running on pump right now but considering e85.

 

[camfast]

There is a big difference between 400hp and whp. If all you want is 400hp + just get an evo 16g for spooll/punch and it will get you there plus more if you have supporting mods when pushed on e85.

Thanks for the help, Ill look more into the holsets.

reply to[B.]: My tranny isnt healthy sadly. the input shaft making a grinding sound sometimes. :/ I thought it was just a throw out bearing but we replaced that and it wasn't. Oh and i forgot to add i have a EXEDY clutch with like 500miles on it.

Well when i say 400hp+ I mean this is the build for now that will increasingly get better and better as money and time come... I'm not trying to buy another small turbo, my 16g is almost brand new.

 

[bluehaze420a]

I just went down this same road of choosing a turbo for 400hp. I ended up going with a s20g (for $325) but there are so many options. If money is an issue holset (hx35/hx40/h1c) will be cheaper but if its not a gt3071r or similar would be awesome for what you want. Like dropthatclutch was saying wait till someone is selling a turbo at a good price. Figure out 2 or 3 turbos that will work for what you want and keep an eye out.

Did you use an oem or aftermarket throw out bearing?

My turbo is going to be at the limit, so i was thinking of getting a Precision Billet CEA 6266, but i haven't seen anyone run one on a dsm.

I just tuned a local's 1g running ECMLink and his mods are Evo III 16g, FIC 1050cc injectors, Walbro 255 HP (not even re-wired), ARP head studs, ETS FMIC, exhaust, and running E85.

With the boost set at 16psi he ran a 13.0 at 103mph before the tune and flowing 30lbs/min. When he brought it over we set boost to 25psi and after I tuned it the car was pulling hard and logging airflow numbers at 37lbs/min with stock cams and stock IM.

All that being said, I wouldn't be surprised if you could get 350+whp on that setup with a good tune running E85 and see consistent 12's in the quarter-mile. I don't bench race though... If you're looking for a bigger turbo to get you there I'd jump on the Holset band wagon and get yourself a 7-blade HX-35 and a BEP bolt-on housing.

Thanks for the input, I agree 350+whp on this turbo would be awesome. looks like im going to be getting a Holset if i can find one.

Aftermarket. it was an EXEDY, and my mechanic said the person i bought the car from just put one in too, thinking that was the problem

 

[Isabelledc5]

Leave the holset turbos on the trucks. They're a waste.

Aeromotive makes the best FPR, stick with 272/272 cams (FP2, HKS, or even Kelford - Kelford cams will need springs and retainers though), FIC 1000cc injectors will do just fine. I'm running FIC 950's with a 60 trim turbo and those are perfectly fine. Get yourself a Garrett core FMIC. Your intake temps will be low.

BAHAHAHAHAHA.

Holsets are going faster than your 60-1, bud.

OP, if you're looking for a bolt-on 400whp budget turbo the 7-blade HX-35 in the BEP bolt-on housing is your best option. It spools just as fast as a 20g and flows just a bit more so no noticable lag on the street when you're DD'ing either.

 

[renovatdkitchen]

^x2 My 7 blade HX-35 with BEP bolt on housing and a FP cast manifold is amazing! It spools insanely quick!

If its a street build and you do decide to go holest, do a lot of research into the oil drain and what manifold you are going to use as it becomes a /really/ tight squeeze at some points.

I really hope my manifold will fit.

 

[renovatdkitchen]

Just wait until you decide on a turbo. Then worry about that. But, the FP manifold is a great unit.

 

[avengerKid]

I'm The guy Gofer (Corey) was talking about. From personal experience i would run the 16g that you already have and spend the cash on a known good intercooler setup as that will have a major affect in the performance of your car. Then gradually build the car for a bigger turbo. The 16g makes for a really fun street car. Like said above my 16g is flowing around 37lb/min on 25psi. Since you will be getting cams it will help the airflow of this turbo an push airflow closer to 40lb/min an put you closer to your goal of 400hp. Overall it seems like your heading in the right way with your build. Hope this helps.

 

[renovatdkitchen]

Keep the 16g, and if you aren't satisfied, get some meth injection.

 

[avengerKid]

Op what fuel do you plan on using? I might have missed that part.

 

[WES_393]

The bolt-on housing will bolt to a stock flanged manifold. The stock style O2 housing will also bolt up, but most use an externally gated O2 housing.

But I wouldn't jump up to a Holset just yet. Like others are saying, I'd run the 16g for a while. Swapping from a 16g to a Holset isn't an overnight affair. Just to give you an idea of the size difference:

And even though your clutch is a new Exedy, it might not handle the torque. I had a brand new OEM Exedy that slipped with a 16g. My South Bend clutch uses an Exedy disk and is currently holding 20psi from an HX40. So find out which clutch is in there, not just the brand.

 

[GSXPimp]

Cant put that power down without a good clutch

This was one of my first questions as well. He said pump for now, possibly E85 later.

Thanks, WES_393 recommended punishment racing so i think i'm going to go with this intercooler. Vibrant Universal Intercooler Rated For 550HP - Punishment Racing
Do you recommend Meth over E85?

Are you saying exedy clutch isnt good enough?

The bolt-on housing will bolt to a stock flanged manifold. The stock style O2 housing will also bolt up, but most use an externally gated O2 housing.

The Oem one. good thing it was almost free. Any clutch recommendations? Also damn thats huge.

Keep the 16g, and if you aren't satisfied, get some meth injection.

Is meth worth it over E85? Around here every gas station has E85.

 

[WES_393]

South Bend would be the way to go, they're very capable and decently priced. You can find them at TMZ Performance.

Earlier I was mentioning that Punishment's kit uses a CX Racing core. If your planning to go pump gas, you might need something better. It's a different story if your going with E85.

So if E85 is readily available to you then use it. That will really let you push the 16g when it comes time.

Thanks, just added that to the parts list.
