table top of toys

[robbie2883]

so here's what i've got to go onto my rb25. most of this is all stuff i had from my last car and is getting swapped over. my goals are 500ish whp. the block is built with jun crank collar, splitfire coils, wisco 8-1 pistons and eagle rods. no head work. current mods are a greddy intake manifold, q45tb, syko IC pipes, greddy IC, greddy type s bov (recircd), syko o2 housing, megan downpipe, QTP electronic cutout and apexi exhaust. all controlled with a PFC.

on the table is cheapo manifold (gonna get fitted by friends fab shop), gt35r w/ 63ar housing (i know it's small but should still flow enough, i hope, and spool pretty fast), tial 38mm wg which i'm actually selling and putting a 44mm on there, turbonetics WIS (water injection system), apexi avcr, aremotive FPR, lines and fittings (just ordered top feed rail, a few extra fittings and 660 injectors), NX nitrous single nozzle fogger kit & ic sprayer, ES subframe bushings, DIF solid aluminum differential bushings and no name RUCAs.

on the ordering list is a oil filter relocation/cooling kit (about to order -8an lines but nor sure if i should go -10?), z32 maf and a swirlpot for the cooling system. anything else in there you guys can give advise on as far as my goals? or things to think about when installing this stuff?

also included a pic of the engine for giggles n grins!

ditch the afc!

i don't have an afc.

snap i didnt see the boost valve behind it, my bad!

Nice intercooler sprayer, they come in handy

man they should throw in warning labels on the box that ship those manifolds in...(WARNING)...i will offer you extreme boost creep...be prepared to modify the outlet for the wastegate cause its not in the proper location in order to maintain boost.

can you lead me in the right direct as to what needs to be done? my fab guy is about to brace everything on it and tilt the flange away from the head a little. i can have him do whatever to the wg outlet as well

[S14-NEO]

i have the exact same turbo manifold on mine and have had it on there for going on three years now...what you will more than liely also have to do is when you are all done welding on it with bracing and all you will hav e to have the mating flange remachined flat cause the manifold will warp . here is a pic of what i had to do in order to correctly solve my boost creep issues. i also had to modify the rear cylinder outlet tube on the manifold as well so i could get the downpipe i wanted to fit properly... the biggest issue with that part of the manifold is the manifold wasnt designed for a LHD car but a RHD car. you have to work around the steering shaft . after modifying that part of the maniflold i was able to run a solid 3 inch downpipe with no issues whatsoever... it may be possible to do without messing with the last runner i just did it to be on the safe side.

[robbie2883]

i gotcha. so you completely moved the wastegate outlet location. i'm going to be building a custom downpipe so we'll see how that works out. is there no way of porting the existing location to keep from creeping so bad? or maybe just be able to counter the creep with my avcr? i just like the clean look of the wastegate being out of site.

[Shocker]

I like most of it minus that s*** manifold and spray bar.

Like they said, going to have to modify that wastegate dump to so it sees proper flow to the gate.

As Carl H might say recircing it will help/might fix it. But I'd rather not find out after its all bolted down, and your on the rollers having creep issues. The placement doesn't get much worse than that.

[gawdzilla]

i'd sell the ic spray bar and meth injection and put the money towards a nice manifold. you won't need either of these "cheats" to get into the 500 whp range.

[robbie2883]

haha...the spray bar is just something i had, i had thought of selling it, i'll have the nitrous already on the car though so who knows? the meth....well, there's a difference from running 500 on race gas and 500 on pump! i would hardly call it a cheat!

What are you gonna be using to tune for the Meth?

pump gas can take you into the 500s. if that is your goal, i wouldn't bother with the extra meth variable

[robbie2883]

i'll be tuning with the PFC, but i'm also gonna tie it into my avcr to run a higher boost level and if the meth dies out for any reason then the avcr will drop the boost

[robbie2883]

[Largekid]

the meth is a nice saftey feature to have, I agree about the spray bar though...that could be put towards some head work Looks like a good start bro.

yeah...i thought about head work, but will i really need it for my goals? like i said i'm trying to break 500whp with it and call it a day. i was under the impression i wouldn't need headwork for this. i want reliable on pump gas. besides...for a street beast anything more is pointless on the s-chasis. it's just too light.

[eh?]

You should really save yourself a migraine and get a 6boost exhaust manifold. I think you'll be okay without the meth kit as you have 93 octane available and have a built motor.

you should do another GB and i'd consider it! LOL

how will the avcr know when your meth dies out? the whole point of meth is to push timing as if you are on race gas. what signal do you plan to feed to the pfc or avcr which will tell either of the two that your meth has run out or failed? in an off chance say your meth pump fails or you run low on fluid. how will pfc or avcr know that? you'll run the same boost with the meth timing. oops. seems dangerous to me. most meth systems have a warning light or something for low fluid, but it's still up to the driver to see it and stop stepping on it.

the meth is a nice saftey feature to have

i'd consider it as another variable that could potentially go wrong. quite the opposite of a safety feature.

maybe i'm being pessimistic or don't know the full features of the acvr. meth does have it's place, but i'm saying it can be dangerous given your setup, and it also unecessary for your power level. it also looks expensive.. $3-500? that's a good chunk of your manifold fund. just something to think about

if you do a tune without meth then when it is added it can be considered a saftey feature...else it can be detrimental.if the avcr doesnt have provisions for an external input that the meth kit can output then perhaps just splicing a relay inline to the solenoid power for the boost solenoid and then using a pressure switch on the meth outlet pressure to activate (or deactivate) the relay would be a quick and dirty way of killing off the upped boost should you run out of meth.I know with my greddy e-01 that it has several pulse and voltage inputs so in theroy i could use it with an external input to kill boost should something happen.I already have it set up so that when running higher boost it references rpm and afr to provide a cut if afr goes above a certian set level dependent on warning.and yes i use my e-01 as my wideband display, works wonders and cuts down on clutter.

[robbie2883]

gawdzilla.....the way i use the meth and avcr is unconventional but i'm know for being a little inventive in the way i make things work.

anyway i always run a 50/50 mix instead of straight meth so i don't add as much timing as i would with straight meth. i aim more for the cooling properties for more boost as opposed to the added octane for more timing. anyway the avcr has a scramble mode. when you give the right wire a ground signal it increases the duty cycle to whatever you set to spike boost. it's designed to be used with a momentary switch but you can also give it a constant signal to just keep the duty cycle of the boost solenoid increased. i'll be tying that into a flow sensor and setting it up with the scramble. as long as the mix is flowing i'll be on a higher boost setting. if i ever run out of meth or the pump fails the flow sensor will detect it and cut signal to the scramble input which will drop the boost back down to a safe level for straight pump gas

the other way is to splice into the solenoid power wire

[gawdzilla]

that makes sense. i did not know the avcr had an external input for scramble. i assumed it would be built in to a button setting or something. sounds like it may work out well.. good luck with it.

[Carl H]

ah interesting use of the scramble switch...wouldnt have thought of that one.

Scrap the manifold. That is the only advice I would give you. It might seem ridiculous to pay as much for a stand alone ecu on a turbo manifold but its well worth it and you get a piece of mind.

i know a better manifold is worth it. but this one was free and i have a good friend that does fab work so making this one work is nothing realy, we've dealt with worse, but i am really contemplating geting a 6boost.

[mott6904]

Whats the point of doing all the work and then restrict with a stock head. I would seriously consider a good port job on the head. There are tons of improvments to be made on a rb head especially on the exhaust side. good luck

itll work if u tune for it. i made over 500 on it, but u just tune for the boost creep (hello 22psi). but being that it creeps itll also affect how you can tune it and your power band

is it really needed though to break 500? i know it will help me reach it easier and more efficiently though. but needed? not trying to argue, this is exactly why i made this thread. for the input of the experienced. who knows, maybe one day i'll do that work. just not big on taking the head off right now. plenty of other projects i'd like to get done on her. just got the ac, now working on cruise and installing some of these toys.

yeah, we were actually thinking of just doing like this guy did to solve teh creep issue. the avcr should also help to keep boost in check as long as the wg is large enough. (i hope! LOL)
