[Oxide_Zer0]

1999 Suzuki Esteem 1.8l
Turbo

Here's some deatails about the set up i'm going to run with
DSM 13G Turbo
DSM Blow off Valve
Toyota Supra sidemount intercooler
EBAY Turbo Feed/Drain Kit
Apexi AFC 5 knob
NAW from 14point7.com
I need to figure out what fuel injectors to use
Custom 3" Turboback

Ummm, good luck with this.

I know that Suzuki's 1.6 and 1.8 engine are good little engines but I've never heard of anyone putting a turbo on them, hopefully you start out with the boost pressure low and work your way up or you may find pieces of the pistons and connecting rods sitting in the oil pan.

But to answer your question I don't know what fuel injectors you are going to need but what you are going to need is to keep the air/fuel mixture where it needs to be, if you run too lean the engine will run hot and possibly melt the valves or pistons and/or both.

Also if your combustion temperatures exceed 2,500 degrees oxygen and nitrogen will fuse together and form NOX which will cause the "Check Engine" light to come on and you will fail emissions testing next time your car is due to be tested.

If you run too rich you may end up with gasoline in the oil (not a good thing) and you will blow black smoke out the tail pipe and eventually plug up your cat with carbon.

What you are going to have to do is experiment with different injectors, fuel regulator pressures, and turbo boost pressures until you come up with something that the engine likes, what I would also do is talk to people that race imported cars (Toyotas, Hondas, etc.) at your local race track and see what worked for their 1.8 engines that will probably save you a lot of time, trouble and money.

Lol this car makes # 37 since i was 15, i'm now 22. It'll be the 4th na-forced induction. i've owned many turbo cars namely mitsubishi's, are the fuel injectors high impedence or low for the Esteem?

I figure I will probably end up running some 360cc injectors, walbro 190lph fuel pump. I just plan on running stock boost 6-8psi, There will be no catalytic convertor. 3" turbo back

Look and ask around the boards, I do not know that much about turboing a NA car, but I have seen calculators on the web for things like injector size and whatnot, we have pretty knowledgeable guys on the Isuzu board, the Impulse RS was turbo AWD.

Indeed i've owned an impulse awd turbo it was a 91 lol i bought it for $400. :-) and i also had an impulse rs wagonback for one day. It was a pain in the A to find some motor mounts for it lol so i took it back and got my money back

Sorry, from your original posting it sounded like you had collected a bunch of parts from eBay and were not quite sure what to do with them, sounds like you pretty much have it covered.

How much horsepower have you been been able to get out of a 1.6 / 1.8 engine?

i've got the 1.8l but I havent set up the turbo system yet. I havent even taken possesion of the car yet. I have to get the rest of the money from my Kawasaki Ninja from the guy before I get the car (so prob gonna get it tomorrow) and no I didnt get a bunch of parts from ebay. Just a few items will come from ebay haha.

Do you have any experience turboing a NA car? The thing you MUST watch carefully is running lean under boost, that = boom!

[Oxide_Zer0]

Yea i've turbo'd a few naturally aspirated vehicles.
I turbo'd my 1.5l dodge colt and i built a 4g63 stroker well kinda.
I've also turbod a honda prelude, and put a t70 turbo on my old dodge stealth automatic

that's why i'm going to be running the apexi afc and the NAW (not another wideband) i should be able to get into the 13's with the esteem before major modification is needed. Its a fairly light car, almost like putting a turbo on a civic only its a lil bit faster base plateform to begin with.

How much of a horsepower gain are you expecting to get?
