no no my d17 isnt 250 whp, i need help to achieve those numbers

currently my d17 is at 6 psi with an ihi rhb5 turbine and fmax fabrication producing 157.8 whp and 155 wtq... i want to achieve around 250 wheels obviously with a new turbo, maybe a t28 BB or easier if a gt28r... im kinda new to this stuff so i really dont know the things needed to be changed to support all that power...all i know is that ill be needing the basic things such as a new clutch,flywheel, fuel pump, maybe intake manifold, add a fuel return, low comp pistons + connecting rods, etc etc.... now do i need to work on the transmission? if so then what do i need to change? will help if you add anything else that is needed to be changed or added...

thanks

You'll need about 14+psi to achieve those numbers depending on the turbo and to run that safely you'll need low compression pistons and rods. Also, to make sure the car drives properly you'll need a superior fuel management system, big injectors, and possibly an intake manifold. You dont need a return fuel rail but it might not be a bad idea for a complete build like that. Good luck it won't be cheap.

just go k20!

 
Rep Power: 282

K20 is not a cheap option either I still think its more economical to turbo. Since he's already turbo it might not be a bad idea to just buy a cheap d17 and build the bottom end and swap that out. There are a few options he can go but all require time and $$$.

why are you saying 14PSI then saying its depending on the turbo? obviously we dont know which one hes going to get, only the ones he has in mind. bigger turbos wont need as much PSI to reach that kind of power. There are people who have gotten as much as 200whp @ 6PSI with a hybrid T3/T4 turbo.

As for fuel management, standalone is a must to achieve those numbers. Anything above 10PSI WILL require a new intake manifold.

14 psi was a reference so he gets an idea of how much boost he would need. Find me one example of a d17 making 250whp on less than 14 psi and I'll stfu. And Chris (wilmnchris was the only guy I know with a d17 making 205whp on 6psi) WITH A PNP HEAD!!

alright thanks guys!

but wat bout the transmission, wats required down there? do i need to change the radiator too?

 
Rep Power: 0

Radiator is probably advised, what part of Paki are you from? Mountains or further north? In otherwords how hot does it get there in the summer months?

You're probably going to want a big (relatively speaking) turbo for your power goals, so you will probably need some slimline fans as well. The stock fans don't give you much clearance. So yeah, new radiator and fans.

If you have a manual, aside from a stronger clutch, I wouldn't worry about the tranny as long as it's well-maintained.

That's what turbo I have and that's my goal with K-Pro. I should be able to tell you if we achieve it in the next month.

At 250HP all day id say the tranny will last 2 years...

there is no aftermarket suport for the D17 tranny. (unless your an auto)

Actually apparently there is. We just found out today that this company:

Team mFactory

makes a final drive that may fit our 7th gen manual tranny. It seems one of this guy's vendors in Singapore (this guy is in Hong Kong) has found that one of their d-sluggo FD gears works in a D17 tranny. He's going to find out from the vendor which one it is and post back up on d-series. It's an odd coincidence, but hopefully it's for the best. More as we find out!

@speedfoos, well yah ppl hav a misconception of this part of the world, paki is quite developed with loads of nice *** cars and roads... jus a few extremists like shoving thier **** in the news that givs the country a bad look, im from the capital islamabad, its surrounded by mountains....

about the tranny, so 2 years eh? im planning to keep this car, n 2 years does pass by quite quickly so what shud i do after 2 years when the trannys' messed up?

well i know this probably isnt much help but this for sale thread said he made 273 whp i believe so if you want to see what his setup is or buy it if that is a possibility...

if im not mistaken the transmission should just require another clutch and/or flywheel when it goes out after that said 2 years but i could be mistaken...

Sorry man, didn't mean to come across wrong. I was just talking from a climate standpoint as far as the difference in altitude between the two areas of Pakistan. Islamabad is on my list of places to visit, some friends of mine have been there and said it's absolutely beautiful. I'm sure I'll end up there at some point.

A well maintained tranny...just keep up on changing the fluids and don't beat the **** out of it. Mis-shifts and speed shifts shorten the life, and the usual, if your tranny starts making a noise, find out what's wrong and fix it - don't just turn up the stereo.

Stock cam will survive just fine, but a bigger cam will give you more power. Cam gear...I don't know. I run that stock one, but I'm at 8-9 psi of boost. I'll leave that for someone else.

@speedfoos, no dude i didnt mean it in that way, jus clearin things out :P i didnt say that u offended me or n e thing! lol

alright then, no work on the tranny... i guess im jus gna change a few things here n there....

n e idea where i cud find that jdm fabtech intake manifold?? other than that coming to the electronics, i hav obd2 injectors and a simple injector controller that comes with the fmax kit... hw wud 550 cc injectors and an aepxi vafc2 be for this?

wat bout other things to keep it cool such as alcohol injection, a new bigger precision intercooler, and or other helpful things such as an hks exhuast manifold, arp headstuds, KMS block guard, oil catch tank etc etc. all worth it? or is this stuff shinanigans too?

lol i jus keep comin up wit questions! about the axels, wats the news up on that? a few friends of mine here hav changed thier axels n say it givs better handling... is it needed? forgot to mention, my cars pretty much brand new, i bought it a year bak n its hardly driven 9k miles, so its not old

Dude, it you want a JDM Fabtech mani, check this thread. Me and at least one other guy are putting our order in on 15 January.

Steve and Clint's JDM Fabtech IM thread

Electronics....what size injectors do you have currently (cc rating)? Not familiar with the fmax kit. VAFC2 is OK for a piggyback but that are several other better piggyback options out there. AEM F/IC being the best, followed by the PCS-XFC (I run this), then E-Manage, then the Apexi products. Quick rule of thumb on injectors. These are estimates but a good baseline. All of these drop into the stock D17 fuel rail with minimal fuss.

- 310cc (stock RSX-S injectors) good for 5-6psi, 175-180whp
- 450cc (stock Acura RDX injectors) good for 10-14 psi, 240-260whp
- 577cc (stock Stage 1 Dodge SRT-4 injectors, I run these) supposedly good about 320-350whp

Bigger intercooler = colder intake charger which = less chance of detonation which in turn = more boost = more whp. Nothing wrong with a good sized IC.

HKS mani? Meh. It's got a T25 flange which is OK as long as you don't have high hp goals (270+). Better off with T3-footed mani if you really want to crank up the boost on a bigger turbo. That being said, the HKS is a solid, cast mani, and you fit a nice GT28 on there. Look at boilermaker1's setup for an example.

Headstuds are well worth it as you can re-use them and the hold the head down better than stock rod bolts. Easy to install and cheap insurance for your motor.

Block guard isn't a bad idea if you want to get into the 300s and stay there safely.

Oil catch can is a must for a boost setup. Drill out the stock PCV valve or replace it with a 1/4" NPT nipple. Run a line from your valve cover vent into a Y-adapter fitting with a line off the PCV vent and run this line into a catch can. Don't plumb the catch can back into the IM without a filter and a check valve.

i see, that helped alot dude! so hw much does this fabtech thingy cost? considering labour is dirt cheap here in pakistan, i think i shud go wit a custom maid exhaust mani... jus an example, we can get proffesional fitting and tuning of turbo kits done within $150, other small things such as catch tanks, exhaust weldings etc etc hardly cost $1 or $2 on labour, at the max if the bastard is feeling cocky that day n wants to rip u off, then $4

It's not cheap. Gerry sells them normally for $1200. We're paying a little less since there are two (possibly three) of us ordering at the same time so it cuts down on the cost.

Since things are so cheap, yeah absolutely go custom. I thought I charged pennies for that kind of stuff, wow. Must suck to try to make a living welding in Paki!

well the only way to find out is if he cranks it up to 13PSI isnt it? if he doesnt, then we wont find out. But you just do some number crunching, it doesnt seem like he would need to crank it up to 14psi to reach 250whp. I mean look at it this way, he was at about, lets say 105-110whp when he started out. At just 6lbs, hes reached 205whp. do you really think he would need another 8lbs to gain 45 extra whp? I mean, i personally think he could do it below 14psi but well never know unless he tries.

Emanage is not the same as a VAFC although they are both piggy backs and add fuel. The emanage is a bit superior from the stand point that you can retard/advance ignition timing and it has a map sensor so the ecu doesn't read boost. There is a great write up from Dezod about all the fuel management advantages/disadvantages. I will try to find it for you but seriously read through all the turbo FAQ stickies. These questions have been answered numerous times but we will all help you with your setup if need be.
