Will This Cam and Turbo Setup Work

[ThatGS-T]

I am looking for imputs estimates and advice here, not a newbie to cars but a newbie t the forum,
building my car into a street race/grudge race/60roll car and im wondering if this motor set up will work for the goals of the car.
Will be posting updates as the car progresses.

4g63t stock rotating assembly (picking up a 6 bolt 2.0 not a stroker to sleeve and fully build next season)
FMIC
arp head studs
arp cam tower bolts
gsc hp valve springs and retainers (kiggly high pressure springs and retainers now)
map 550
whp e85 kit fic 1250cc injectors AEM 320lph fuel pump with AFPR
dsm link tuned
hx35 billet internals(twin scroll housing if i find one)
3 inch turbo back with header
gsc s2 cam with adjustable cam gears(cam choice is what i really need help with these are only good to 35 psi)

my goal is 500hp roughly car IS NOT a daily driver only comes out for races and street test passes(and standing half mile runs once a year)

im not worried about this set up on the big end where im pretty sure it will perform,
where i am concerned is will this set up perform in a grudge race from a dig, car will be on slicks so boosted launches are in the equation.

Need help choosing a cam for this turbo that can handle power since im not sure how turned up this turbo is going to go but i thinks its safe to say 30psi is a possibility

Go HX-35 and Delta 272 cams. 1200cc injectors and a 450LPH pump. 1G fuel rail with -6an fittings would be nice too. Tune on E85 and you should touch 500whp no problem with your other mods. HX-35 will launch better and spool better in your setup. I personally am a fan of Kiggly beehive springs just because I hear awesome things about them a lot. I don't think you need cam cap bolts for that build. Which manifold do you want to run? Why not a GSX BTW or do you plan on swapping it?

Just look up richard33 his setup is what your after are you auto or manual?

plan on swapping to gsx eventually, im looking into the JM street or race sheet metal manifold with a 1g throttle body swap, cam bolts are just to be safe since im in there, also looking into a twin scroll housing for the hx35 if i can find one, for e85 i just need stainless lines and fittings correct? MAP sells a 550whp e85 kit with 1250cc injectors AEM 320 lph pump with afpr fuel pressure guage fuel rail adapters and 4ft stainless lines for 760$ looking like no more pump gas for the car

 

[ThatGS-T]

Appreciate that!

decided i willbe going with kiggly high pressure beehive springs!

 

[Dsmkauai]

Me to love manual and will always rock it!! Haha make sure you put a Quaife LSD in your budget if you want your gst to get any kind of traction

im thinking about doing that along with a shep trans then i have to shop around for my axles

 

[Dsmkauai]

Good luck with a shep trans . Unless used. I use Brian terhunes axels they are beefy and cryo treated for super strength. Just depends on how you launch. Some guys go with parts store ones or raxles that have lifetime warranty. So when they break they can get replaced. Don't have that luxury here on kauai, why I went with Brian's. Didn't want to deal with it after breaking a few at the track. Plus he's my guy and gives me the hook up Look into a Southbend clutch setup bro hands down the best out there!

This will give you a good idea of what you'll need:

Also, if you're picking up a 6 bolt wont you already have a 1G throttle body? Careful torquing those cam caps down, they only get 15 ft/lbs. A lot more than that starts eating into the oil clearance since it is just a journal. HX-35's and twin scroll manifolds pop up here on the classifieds every once in awhile. Usually 1-2 times a month. Keep your eyes peeled. Also, cant go wrong with southbend or ACT.

 

[bastarddsm]

Those GSC cams should be a good choice for any medium to large size turbo. I don't know why they say "good upto 35psi" I suspect they are looking out for drive pressure, and perhaps they don't handle high exhaust pressure well?

If your looking at the HX35, don't be afraid of the HY35/HE351 on a turbonetics manifold. Rock solid durable consistent power.

im not picking my 6 bolt up until the end of this summer and hoping to pick up just a cheap short block to sleeve and build ect. everythings going to be torqued to spec so i hopefully dont trash anything, but as far as the housing a twin scroll would be nice but my housing choice is still up in the air since it spools decently fast as it is, also looking to going billet internals and unsure of my blade choice still.

yeah i dont uderstand why they can only handle "35psi" i might have to try calling them to see if they can clarify on that, im just wondering if there would be an issue going with a cam designed for larger turbos than a hx35 but i cant see why there would be

 

[ThatGS-T]

Thanks everyone for the help so far its much appreciated, figured since i am new to the forum i wasnt going to get nearly this much help

 

[Chumpaumpalumpa]

Wiseco/Eagle is a popular combo as is Ross/Eagle. If you're only running on E85 or racegas, then 8.5:1 would be good or maybe even 9:1. Call GSC and ask about the cams.

 

[ThatGS-T]

im thinking about going to around 8.5:1

You don't need to sleeve the short block unless it's already been over bored .040 or more and is out of shape. That would be waste of money. I also wouldn't waste the money on eagle rods, unless you plan on having their balance checked after getting them. 35 psi is a very broad range/statement as it is different with every turbo and setup.

 

[Diamond Star Werks]

Bushur cams would be a better choice than the S2s. They would give you a broader power range and make more power throughout the whole power band.

I wanted to sleeve it so I could run possibly a bigger turbo and more boost in the future and to be safe and don't want to even give the block a say in how much boost it gets

Ill start looking into them and reading up on the can info in that link, the s2 is looking to be not the route for the car anymore with this info

 

[ThatGS-T]

Definitely looking into Bushur 272s because they are supposed to have a good quality cam and I don't want to spend the money on Juns and they are hard to find

 

[Chumpaumpalumpa]

You wont need to sleeve it to run more boost unless you plan on running like 60psi.

 

[donniekak]

I run 40+ psi on a non sleeved block, and others run 60+.

It isn't a Honda open deck aluminum block. The 4g63 is a closed deck cast iron block. Unless there is a huge over bore, or casting issue its rare to crack a 4g63 bore.

The biggest issue with high boost 4g63's is head gasket sealing.
