Well total original budget for the build was around 2k. Which still should be achievable with quality used parts. These parts will be collected over time though. My time frame is to be done and ready for next summer. No point in a turbo when winter is near.

Things like this are what upsets people. You need to define your mission, budget, goals, HP requirements, how you will use the car. This is what the Meet and Greet can be used for. That way, people can make suggestions ACCORDING to your needs.

We will help if we know what you are looking for.

Thank you for being a smart *** about the meet and greet part of the forum though. I felt like it was appropriate. Instead i would work on your people skills and maybe suggest going to that part of the forum to introduce myself, because honestly i overlooked it.

Thanks for the welcome though. Hopefully not everyone is this rude here.
I'm in the customer service department. Sir, take a number, please. I'll be right with you.

I was kinda being a dick, but I was also trying to point out that we still don't know answers to the basic questions that would help us help you. We want to help but you have given us nothing but "will this crap work" and "I really need to stay under $500."

If you wanted a drag racing turbo that was cheap and effective I would suggest--- Search for a thread started by "dvcn" regarding his $159 ebay turbo. But if you were autocrossing, that would be a bad choice.

If I knew if you could weld I'd suggest a couple of threads to read regarding building your own manifold. Several here have done that. Can you weld? We still don't know.

We don't even know if you have a 1.6 or a 1.8 to be able to direct you toward particular products and/or sizes. Things that work well on one might not even fit the other.

As one of the senior members of this forum pointed out to someone who came before you asking a bunch of questions without reading or providing necessary background to properly answer his questions:

Actually, $2k is achievable with new parts, and in kit form, no less.

BEGI Shanghai-S Turbo System 1994-1997 BEGi

Here we have a non-intercooled system using an AFPR for fuel control. It comes with a good quality manifold and downpipe, and although some of the other parts are bargain-basement, this will be good to bolt-on and go. There is some value in this, as it's a good way to get you feet wet and at least get into a running system with minimal frustration.

As time passes and the boost addition grows, you can add an intercooler and swap out the AFPR for a MegaSquirt, injectors and WBO2, and have a very capable system.

Ah, see now that makes more sense to me. I know all forums are not alike and have different rules. Like i said before. I'm quite newbish to this and am just setting a rough goal. I just took a guess as to where to ask for help here.

I will apologize for the ignorance. If the mod would like to move this thread to the welcome and greet ill be more than happy to change the title and continue with the discussion there. Once again i do apologize but the inappropriate flaming when im completely unaware of what i did wrong or have not done right really wasn't necessary.

alright so what is your total budged for the entire kit?
do you have any parts that you have bought so far?
do you know what parts a turbo kit requires?
Next, read this link if you are deciding to go with an ebay kit or ebay parts as it will teach you a lot.

at last the info you posted here is correct right? i was confused why people are posting 1.6 stuff when your sn says 96...1.8L

Why do you say that? If you haven't ridden with him at an auto-x, then you don't know what you are saying.

It wasnt there 10 min ago lol. They were guessing sense i did not supply enough info about the car which is my fault. I'v only had my car for about two weeks now and love it. I want some boost now though. The plan is to get the turbo and fittings now sense the turbo can be had cheap used. I work at autozone so im sure i can source the oil and coolant lines for the turbo. Im not sure what fittings to use though. Id like to use a good used t25, preferably a Garrett.

The bigger items like DP and Manifold will be bought come tax time. I know some of the bigger pieces i need. I'm more confused on the turbo lines and where they go. Or where to tap into my oil pan or even how.

It is what I would want for an autocross, but big lightswitch turbos are much less controllable. Lack of mid-corner modulation and off spool torque are the biggest complaints I've heard about big turbos. That's why so many autocrossers go with small turbos or superchargers instead. I actually love dvcn's setup and his autocross videos (as I have posted previously). I would choose his setup for my own car, not for practicality at the autocross, but for its pure uncontrollability. Trying to control the uncontrollable sounds like fun to me, but that doesn't make it easy to drive.

If you dont have the money now, I will recommend you hang around here with us for a while and check the forums regularly, you will find good stuff. For example i just bought a professional fuel control unit (that will allow me to pass emissions) for under 700 bucks.. retail price is over 1100.. i also bought a very shinny begi-s kit for nearly half the price of the new stuff.

Personally i wouldnt pick parts on my 1st kit. I dont know how much experience you've had with turbos but i assume you've never installed a turbo from scratch in your life (same here).

I would recommend a nice Begi-S since you are a beginner. It will cost you a little extra but you will know that you will have a good reliable kit that you can boost to a lot more later.

You can also check out the shanghai kit which is cheaper and still made by begi but it uses a chinese turbo charger.

if you are set on building your own kit, read the installation instructions for the basic kits and this will teach you where the lines go to.

There are several fantastic write-ups on the oil pan tapping procedure with some really good pics here on the forum.


There is no one right way to go with turbos and manifolds, but there are several wrong ways. Just take your time and put the research into it so you don't end up unhappy after spending a lot of money. There are a lot of successes and mistakes to read about here.

Good luck.

I wouldn't mind the chinacharger kit from begi. Its what? 1500ish. 1600 shipped? Is this what you would recommend? Do i need any of the extras or can i just buy the kit as is and go? I saw there is no boost gauge with the kit or BOV. Is 5-7 psi low enough for this not to matter? I don't want to blow my motor but i don't want to start of with to much HP at once. Got to learn how to craw before i can walk. With that said i have built a 300hp 4.6 in a mustang but thats also a bigger car.

Thanks for the advice. I will keep my eye open there then. I'm trying to avoid a big mistake. I would rather look like a noob and ask a dumb question than dump cash were it need not be dumped.
