i know that it has been done, but what specific parts have you people who have done this used. I know i need sleeves, pistons, maybe rods?, nice valvetrain, cams?, good tuning parts and maybe a nice IM. But what compression ratios have people used and if cams are used which ones? I don't really want to rev over 8k if i dont have to. Also what would a good turbo choice be. My friend has a t3/t4 i believe its a 48 ar and 56 or 57 trim? so i'm thinking about buying that from him. good choice? also would 770s be enough on the injectors or should i go higher? anything else i would need?

 

You could power a friggin tractor with 770's. Stock Supra injectors are 550's.

 

that turbo is a lillte small to be making that kind of power...you need something like a 60/63 trim......................get ready to spend lots of money...

 

yo look up chrisricketts threads he's done a solid turbo build...hes pretty knowledgeable about the turbo stuff

Stock Supras also have 6 injectors.

aww shucks..........i feel honored.

anyway, 770cc injectors would be perfect, which means........get 1000cc injectors. if you make 450whp then you'll want to make more eventually, so you'll want to tune on race gas and higher boost, so you'll end up needing those 1000's. it won't hurt anything if you never get around to using them to their full potential though. the tuner will make them give the amount of fuel they're supposed to give. i run precision 1000cc injectors. i'm still saving $$ to tune, but i should make around 400 on pump, and 600 on race gas.

by the way, if you don't plan on using race gas, i'd stick with your stock ignition, as it is much more durable and useful high in the power numbers than most people think. i'd be willing to bet that a COMPLETELY new stock H22 ignition could make upwards of 650whp. that's new everything though. so i'd change your cap and rotor, get some fresh plug wires (stock will be fine), and a fresh coil and a good grounding system, and you won't even have to worry about an high cost ignition systems. or you could buy my MSD digital 6 box brand new for 280. i'll throw in a used blaster ss coil for 20 more bucks.

fuel pump- walbro will be fine. i have one used for 60 bucks.

turbo- get a precision SC61 (that's what i'm using) great "bang for your buck" turbo. the one you mentioned won't make the power.

buy a bunch of mandrel bends and make your own intercooler piping, and even downpipe and exhaust. that will save a little money. 2.5" on i/c piping and 3" on exhaust and downpipe if you don't mind cutting into the crossmember a little.

get gauges so you know what's what----at least boost, oil press., and wideband air/fuel.

get a good manifold. i suggest a 1fab or lovefab or neukin or even better, a full race manifold. these are all a bit expensive, but you need a good mani.

for an EMS, use crome or hondata s300/boost or neptune.

i recommend jason (st00pid) in houston, TX for tuning or Tony Palo (Tony1) in Dallas, TX if you are anywhere near Texas.

sleeves- Golden Eagle HD or Benson
compression ratio--- 9:1 is good
rods- manley or pauter
pistons- CP or Endyn rollerwaves
cams- leave them stock

if you have more money after all that.......
PNP the head, get new valvetrain (i used ferrea), theres also skunk2, supertech.......etc.
intake mani- just get a large volume intake like venom (what i used) or the best is probably Golden Eagle.

hope this helps man. good luck.

Supras also have 6 cylinders. Whats your point?

 

i'd have to agree with what chris said.... and if you're looking at 1000cc injectors I have a set for sale, used for only about 10 minutes.

they use 6 injectors @ 450 cc, resulting in 2700 total cc, to get that with a 4 cyl, you need a little under 700cc from each of the 4 injectors, so 770s would be perfect

means that your post above just proved that you dont know what you're talking about

 

a stock mustang gt (not sure about the newest stang) uses 19lb./hr, or roughly 175cc injectors. usually when a motor has more cylinders, less fuel is required per cylinder. i imagine that this is because of the greater momentum and torque that they create due to the greater rotating mass in the V8........(am i just talking out my *** here?), so that they require less fuel per cylinder to make things go. does that make sense or am i an idiot? i believe that their cylinders are also a bit smaller than ours as well.

i guess that under that thinking, they'd need more fuel to get things up to speed, but less to keep it going. i don't know, someone drop some knowledge on me........where you at PrecisionH23? make me look stupid here.

 

Correct me if im wrong, but Supras have 550cc injectors. My point is that 770cc's is a whole lot of fuel. You could use 650-700 instead and achieve the same goal.

chris that is a lot of *** talk up there , ill try to shed a little bit of light on it....

if you break it down to the cylinder level, there is no difference between a 4cyl and a v10, i suppose you could make a v8 turn with less gas but that would not be desireable, more gas exploding=more power, period

the size of the injector is not the only variable at hand, you have to consider fuel pressure and duty cycle also

there is no reason to buy smaller injectors when you have an EMS which is able to adequately control bigger ones, 770cc just happens to be the most popularly available size....

 

well.......i was just guessing, i know there's some reason why a much more powerful mustang gt uses smaller injectors than a much less powerful honda engine. thanks man......

oh yea- if 770's work great , then 880's would be so nice......so get 1000's! i don't know if that makes any sense, but if your EMS can control the bigger injectors, you should get them, because you can always use more fuel in the future, but you'll never need less fuel in the future. it leaves room for upgrades later on.

 

I guess so. But how much fuel could you possibly use?

its all about airflow, a rustang isn't going to be reving to 7500rpm where there is a **** ton more air flow hence more fuel required. you have to match the amount of air being drawn in with proportional amounts of fuel. Boosted hondas need such big injectors because the air demands are huge. for this particular goal i would say the 770cc is proably the min that you should go you might get away with it but be knocking at 90+ % duty cycles in boost at high rpm.

there are many good injector calcs at rceng.com

just keep in mind runing a engine close to 8k boosting 1 bar or more at a 11.7:! a/r ratio is a **** load of fuel

where a 5.0 mustang thats no reving past 5500rpm (??) runing at stoicho mixture = not so much fuel

 

you gotta take into consideration the volume of each cylinder of a 4 cylinder vs 6 cylinder, yes you have bigger displacement with more pistons, but the bore of each cylinder is smaller than the block of a 4 cylinder

thats why the injectors are smaller

 

I recommend golden eagle sleeves, Mahle pistons (9.0:1), Eagle I-Beam rods, a new OEM honda crank (have the whole rotating assm. balanced). Also a good set of cams. I would use a crower stage 1 on the intake side, and a stage 2 turbo cam on the exhaust side. I have seen this setup used with great results. Also, invest in a good fuel management system. You will probably want to use the Skunk2 IM, since the H22A4 IM uses a dual plane design. You could use a jdm accord euro R IM in its place, but it uses EGR, which is a down side. 650cc injectors should be enough. as for the turbo, I would use a garret GT2871, GT3037, GT35R or something along those lines. It all depends on if you want more driveability, or more top end boost (which makes for a shitty power curve, and a small power band which is only at high rpm)...

you have the first part right, you need to take into consideration the volume of the cylinder.. but more importantly rpm hence air requirments. a 5.0 mustange has 5000cc of displacement which = 625 cc per cylinder, a prelude has 2156, so that 539. even though the cylinder of a honda has less displacement than a ford 5.0 cylinder the honda needs the bigger injector to meet fuel requirements with some buffer built in for the air flow that a hihger reving motor sees.

 

I see. Good stuff
