Stroke or Head? haha
Stroke or Head? haha
No I am not being dirty... I am wondering which I should do as of now...
Mods:
Hks Rs Kit
Power FC D jetro
950cc Injectors
Walbro 255lph fuel pump
BR 3" turboback
Apexi AVCR Boost Control
NX Wet kit (goin in next week)
I have about 3000 to spend right now I am thinking of the Head that quantumn racing offers BJCH Stage 5 head or the AMS 2.3 Stroker kit...Stroker I want to do the Piper Rally Cams as well so I am leaning towards the Head but with the nitrous the stroker kit would be great as well... I just wanted to see what some of you thought. I will be doing both eventually but this is just to see which goes first... GT35R is coming....(even if it is after both of these in 5 years... hahaha )

well first off just to clarify the head is only 2K plus the cams which is about 1K same with the stroker which is about 2k plus cams which is about 1500-1600 because I will have to buy springs and retainers

If you run the stock turbo on a ported head with high lift Piper rally cams and a 2.3 stroker youll have insanely quick spool and a mountain of low-midrange torque. Your turbo will probably run out of steam around 5-6k RPM. The engine will simply flow way more air than the turbo can and boost will fall
If I were in your position Id just do the piper cams. Since this forces you to upgrade the valve train, you should go oversized 1mm on the valves with some headwork. Upgrade the internals when you do the turbo kit.
I dont know why you have NOS. I wouldn't use it on the stock internals. Should have waited until the big turbo and stroker kit to go NOS. Just my opinion.
Since you already have the NOS perhaps a stroker and big turbo kit will work better for you. NOS can spool it the stroker will hold the power and the turbo will provide more then enough power. I just think going the piper+headwork is better since you can use it on a regular basis and not only when the bottle is full. Plus this will get you ready for the bigger turbo and stroker down the road.

see thats why I was leanin towards the headwork, because I have to upgrade springs and retainers at the least... so why not do the whole thing... dont know still undecided maybe I will save for turbo and do both of these after...

hey guack what do you think the cams would do on stock turbo, head (upgraded springs retainers and valves to support though), and 2.0 liter

OK - I have the Piper Rally cams in my Evo (plus ferrea valve springs and retainers) on a stock head with stock valves and a stock turbo. The cams added nice, fat power (about 40 whp so far, but I still need to tune more) but are definitely capable of more than the stock head can flow.
My next mod will be having the head ported and larger valves installed as preperation for moving to a larger turbo. Mark at Quantum did a great job of getting my cams and springs to me - he also works with BJCH for getting heads ported.
Oh, plan on getting some cam gears, they are needed to really capitalize on the cams. The gears added about 12 whp over stock 0/0 cam timing with the Pipers.

Can anyone tell me whether BJ's is still having "issues"? Last I heard there was no E.T.A. on when they'd actually be fulfilling orders for head work, so what other options are there besides Buschur and darkhorse?
Stage 3 Head from Buschur - $1600 Dollars
It's the best head money can buy. Do a search, he's flowbenched his competitors.
Don't bother with the stroker because it's going to cost more than 3K to do it right (assembly and labor). And the 2.0L rev's really nicely.

Head in stroke go hand in hand don't they
? Don't think you can do a stroker kit without the head but you can do the head with out the stroker. The latter of the two options would be over kill by itself, unless you get a new turbo. If you get a slightly bigger turbo, build the head, add a thicker gasket, you can boost and achieve a lot more power, and consistant power compared to NOS. I think NOS is good for drag racing, but if you like to use the car for track or twisties you need consistant powerband. Don't buy the NOS, save the money and get a bigger turbo. NOS breaks things. Or better even, if you can do it, save your money and do it all at once so you can get an even larger turbo, head with a built bottom end. That way all the parts are matched and you don't waste any money.
