I already have a walbro 255 fuel pump what other things would you recommend before I install a turbo kit?
P.S. When I get off work I am going to search for diy turbo.
Is it hard to put together a turbo kit? I am pretty good at following directions.
Thank you sol
A turbo Kit is the easiest thing to put together. Go to
www.stealthmode.com for oil lines. Before you buy your oil lines find out what turbo you wants. Dont get somethign overly large like a precision SC61. A T3 .60/.63 will do fine Slightly larger is fine as well, but spool up will be longer. "Turbo lag" is a myth created by people who are too damn anal about turbos and try to scare peopl eaway from them. You dont even notice it when you get on it in 1st. Which is the only time you should be gettign on it (at a track).
Find yourself a good intercooler. Do some research on tube and fin
and Bar and plate designs. Bar and plates are more efficient, but slightly heavier. Some T&F are just as efficient as B&P.
Buy some aluminum pipes or stainless steel pipes for the intercooler piping. Have a professional weld these together for you. They willl need to have your car to do this. Go ahead and take your bumper off for them to do it. Before you even bring it to them, mount your FMIC so you can adjust your bumper how you need to (cut out pieces).
Choose a Blow Off Valve. blow off valves release boost pressures between shifts so you dont get the pressure slamming back into the turbo causing compressot surge. This can eff your turbo and motor up.
Get yourself a 2.75-3" exhaust. the larger teh exhaust teh quicker the spool. I got my exhaust from
www.kteller.com I bought a mild steel kit for my car 3" and one resonator. Sounds great and spools fairly quickly. Buy flanges for the downpipe/tuebo and have the shop that does your intercooler piping make your downpipe as well.
If the turbo you choose is an actuator style. then you wont have to worry about this step:
Choose a good external wastegate for your turbo. Tial makes good ones. Stay away from teh 35mm though. they are just a watse of money. for the same price you can have a 38mm and it will perform better. I am using a SSAC 38mm wastegate right now, and I dont have any problems with it. It is identicle to teh tial model. DONT GET A DELTAGATE. they suck at regulating boost pressures.
Buy a good manifold. Stay away from ssautochrome manifolds. they are complete shit. Blox makes a good design log style manifold. or you can go with LoveFab. He makes good manifolds and has great customer service as well. For an external wastegate, the ideal location is on the collector so it releases exhaust from all 4 ports instead of just one or two.
Buy a boost gauge. You will need this to know what PSI you are running.
I wouldnt waste my time with an A/F gauge unless I had a wideband o2 sensor hooked up.
Buy an EGT gauge. Put the probe on the third runner no more than 2" away from teh head.
Buy some sort of Boost controller, if you plan to run more PSI than what the spring in your wastegate is set for. I swear by manual boost controllers. the TurboXS dual stage is great. Stay away from electronic ones. When they work, they work well, but half the time they dont work. Piles of shit imo.
Dont forget about engine management. Stay away from FMUs. they arent very reliable beyond 6 psi or so. If you have the obd0 B16A swap, then you probably have a PR3 ECU. If that's the case go to
www.forum.pgmfi.org and go to the BRE forum and read up on it. I am using it to control my timing, ignition and fuel maps and I couldnt be happier with the results.
You will need larger injectors depending on the size turbo and how much boost you intend to run. I'm running DSM 450cc blue tops in my crx with b16 swap with a T3 .48/.60 at 12 psi and it is fine. I woudnt go past 12 psi on a stock B16 though. 12 sometiems scares me on this thing(stock motor).
You will also need a larger MAP sensor. you can get the motorola 2.5bar or a GM 2 bar or GM 3 bar. I am using a GM 2 bar. it is ok up to about 16 psi I think. Then you will get a cel and limp mode.
Do some research on all the things I have mentioned so far. I pieced my entire kit together for under 2K and thats even with buying new motor mounts for close to $400. If you have any other questions feel free to ask.
