Its been a long time coming but shes almost there
 

Well I finally got some 1.8 axles for my rx7 lsd and the rest of my turbo kit kinda together. I'm super excited to finally get to drive her again (let alone boosted!) thing is I've had this thing on the go for so long I've prolly forgot something and would rather someone tell me now then later.

A recap:

I have a custom SS-304 manifold and 3'' downpipe (head flange needs to get tiged on and shes good to go)

Srt4 intercooler with greddy type-s bov, 2.5in SS i/c piping

-3an feed line, and I think a -10 drain

T25/28 or something or other turbo lol (it fits so thats all that counts)

FM coolant lines

Civic half, dual core alum race rad.

I have emange blue installed, (no map yet, hard to find round here) but I haven't upgraded the firmware yet, tried, didn't seem to work for some reason.

RC 370cc injectors and a walbro 255 installed (shoulda went 190 I know)

So I need a map sensor and a wideband and...well I think thats about it.

So what else am I missin here, maybe an o2 clamp and siome dyno time I guess. I can't wait to get her on the road again, after two diffs and a summer waiting for axles I'm gonna b driving (or trying atleats) hopefully this month, did I mention its been -40 and theres a good foot of snow on the ground lol.(weather this week actually is insanely high, 2above):eek5: :bigtu:

Are you planning to run stock fuel pressure? I don't see a mention of an AFPR. How much boost are you planing to run?

Jay

you have an emange blue, you dont need the walbro 255. You can run the stock fuel pump, should run the stock fuel pump. Also dont need the rrfpr.

Brian

EMB + 100psi = more fun

so what you are saying is...... more fuel = more power = faster!!!!! :gay:

Hell I'm going to go outside and pour some gas into my cylinders and set a land speed record!!!!11:greddy:

Brilliant!

Brian

If he wants to run more than 160-170whp he'll want to run more than stock FP.

Run 330cc injectors at 100psi and your technically running 500cc injectors. It's not just about adding more fuel, but flowing enough to support additional HP.

I'm looking for 200whp, Hence the pump and the 370cc's. According to RC's fuel calculator that should be about right.

I shouldn't have to run a shitty afpr to get over 200whp with emanage and 370's...atleats I better not after giving away my aeromotive unit.

I don't think you've got enough injector.... it's close, but it's looking more like 200 crank than wheel. What are your assumptions?

hmm i wonder if the 255 will over power the stock fpr...and by how much...ohwell i guess i'll have to run a lower power level until I get that sorted out.

Yes, from what other have reported with that pump, I would expect 5-10 psi additional fuel pressure at all times.

Hopefully with the emb you can get a nice idle. You might need to tweak the idle mix on the afm a little (assuming 1.6)

I'm curious about the SRT4 intercooler. It fits?

I only ask because the end tanks shoot the pipes straight back..

1.8 but in a 1.6 car.:cool:

I have a honda rad which fits inbetween the intercooler endtanks:bigtu: they will get sandwhiched together to save intercooler pipe length and cuz I think it'll be better than the conventional i/c way up front set-up.

So how should I raise my fuel pressure then, I kinda want to run 12psi but deffinately want it safe (non of this 90% duty cycle stuff).

I don't want an afpr though...Would a dual feed rail help much?

Sorry chief. Not happening. You'll only have enough fuel for ~200 crank hp.

You need a fuel pressure regulator, or a different ecu & bigger injectors.

Jeesh its been so long I must have forgot my horsepower goals lol, guess I was aiming alittle low when I started to piece it all together..

Hmm so either get an afpr/ better ecu/ bigger injector...Well emange can't really mange a much bigger injector...I could go to a stand alone ecu I spose... I don't know if I want to run 100psi of fuel pressure either...

Thanks for the help Ben.:)

As is, you'll get 50-60 psi fuel pressure. You'll need 70 psi to break 200rwhp with those injectors. Since you already have the emb, why not just add a fpr to it?

Do you know what it's from? Any pics? Also, is it a stock Honda rad or an aftermarket one? Do tell..

any photos?

just buy a used vortech from someone and run those injectors at higher pressure in boost. Tom and Bruce were making over 200rwhp with the EMB/FMU combo.

Where'd you get the axles? How much?

he doesnt even need a rising rate like the vortec. a simple fpr will do.

Its aftermarket, not sure what car exactly, (prolly civic). Like i said Dual core, all alum.

hahaha FM man!!! I ordered a set from miata-parts on evilbay and they never came...no money back either, I posted in the good/bad trader thread about them. But ya they came up on Fm's salvage section and i bought them the next day, 75buz hahaha, they're brand friggin new I swear.

Sorry no pics as of now but I'll grab some tom and post em up soon.

So the aeromotive 1:1 rising rate regulator would have worked then? Well maybe not cuz it was only 40-70 base pressure adjustable...

I do I go about running one with the stock one there, I imagine I'll have to remove it and rig something up..

I didn't want to run an afpr cuz i heard they were unreliable and finiky..

Your stock FPR is a 1:1 also. If you want to raise fuel pressure beyond stock, you'll need something else, like BEGi's or Vortec's AFPR/FMUs.

Dean, I might have a BEGI AFPR forsale. It looks like the previous sale has backed out. I just rebuilt it with the kit from Bell.

PM me if you are interested.

Well my manifold is getting tiged up right now, b done tom as will the diff (just had to get the bushings swapped) ya for me!

So running some nice high (like 100psi) fuel pressure will give enough fuel so my next bottleneck would b the turbo, not the fuel system...

Manifold is finished and looks good, they even ported it out afterwards, which is expected but nice none the less. (Pics will b up this evening)

Picked up fittings today, still need drain flange though..

Oil drain is -8an and feed is -3an...Got a 45 for the pan fitting aswell. Someone want to confirm these sizes are adequete for the t25?

Everyone seems to run -4's but they didn't have the metric fitting for the block in -4..

Next is find a drain flange, clock turbo (center housing), (get down pipe rewelded maybe, as the welds are a joke) and tap pan..
