I am looking on purchasing some preformace injectors, (getting the car ready for a turbo)

What should I get and what exactly do I need to change before I put the a turbo on my car.

Oh yeah its a stock 93 DX HB.

Fuel managment (computer), injectors, and fuel pump are the most important. Everything else is kinda-sorta secondary.

Plan to spend a good chunk of coin on this project - don't believe the wishful thinking that you can do it for $500 When I bought parts, my fuel pump and injectors alone were $500. You want a GOOD fuel pump. Walbro would do... but I chose a Holley which is a almost double the price.

I am looking to spend about 1000. You know any cheap places to purchase a fuel management computer and fuel pump, and sorry man 280 is too much.

Also what kind of fuel pump and fuel.. computer would I need.

good luck to you

cheap injectors...go to a scrap yard and find a turbo talon the auto's are 390 cc's and the manual's are 450 cc both will suit you fine shoudl be fairly cheap..then get a apexi afc which will run about 300-370 bux..then get a walbro 190 fuel pump..while yoru at if you can rape the turbo talon for an intercooler and turbo aswell...

even DSM 450s run $100 and then you gotta send them out for cleaning and balancing, so add another $100 to that... plus you need a resistor box to run them... another $20. Then you need a manifold ($350 or $150 for an HF one plus adapter plate), computer ($350), pump ($200), turbo ($250+), intercooler ($100), piping ($150-250), down pipe ($100), oil lines + coolant lines ($$$?), gaskets ($100), clutch ($300-400)... and then you can run boost. Oh, and you kinda need a 2.5 inch mandrel bent exhaust and 2.5 inch cat too - another $500. and that's just a cheap 8 psi setup.

I know cuz I've done this before... it can be done cheaper, but at the end, it'll still cost you that to within 10%

How much boost are you planning on running? If you're going to stay under the 200whp/8psi barrier, I'd recommend keeping your fuel system stock (including injectors), and buying one of those FMU's or a Greddy blue box from a 5.5psi kit.

imported_dwiniarz

Yeah I am going to keep it stock, and run like 6 psi.
What kind of FMU's would you recommand

dropgear

Recommend? I'd say the vortech disc based one (10:1 in your case) is pretty much your only option.

If you have the money, people swear by the "AFC Hack", which requires: Apex'i AFC, larger (450cc?) injectors, missing link to hide the MAP signal, and possibly a resistor box for the injectors and fuel pump.

Ideally, you'd get a chipped ECU (from a vendor like Hondata) that handles boost, and an ODB2->OBD1 conversion harness (with fuel system upgrades as required).

You dont use a missing link with the AFC hack....Also you only use a resistor box IF you are using PEAK AND HOLD injectors.

cee_mon is correct

under 10 psi, you don't need a missing link or check valves

civicex

at what psi does the MAP sensor through a CEL if one is trying to manage their fuel with a cheap Vortech disc?

I thought if your MAP sensed any positive pressure then it would send a CEL, therefore check valves were required for any setup that wasn't an AFC hack or complete independent management (i.e. AEM)?

cee_mon

The magic number for the AFC hack is around 10.7 psi.....go over that and bam CEL code.

civicex

but you need it for .0005 psi boost with a Vortech disc only correct?
