Sure thing, once the turbo arrives I'll take some pics.

I can post a link to the item I won if you like. I haven't purchased anything else.

Here's the link to my turbo: http://cgi.ebay.com/ebaymotors/ws/eB...m=180455118547

You do know that people have blown engines from running those junk ebay turbos right?

So if that happens then you will have to sell the car.

You should have put that $600 into a beater DD.

Azriel, I'm genuinely interested in your progress. Could u do me a favor and post or pm me a budget with all the different things u anticipate to buy. I am knee deep in my single gt35r upgrade so the process is very fresh.

I once tried to turbocharge my 1990s Pontiac sunbird. I got a turbo and manifold from a 1.8l similiar car. Thank god the exhaust mounting didn't line up. So, in a weird and twisted way, I've been there too.

I've got all my twin stuff pulled fresh out so if **** hits the fan, let me know. I'm not supporting the eBay turbo route but I'm supporting a fellow forum member in need. :-)

The ebay turbo's aren't good. Well unless they are an actual brand name turbo just being sold on ebay. But the SSautochrome turbos won't hold up. Some have them rebuilt with garrett parts, but then you're adding $200-$250 to the cost of the turbo. genuine Masterpower turbos seem like a very good option for a budget build.

Both the manifold and wastegate should be fine for street use. If you get a knock off tial you will have to cut the HKS flange off and add weld the tial on there. (it uses vband) You will also need block off plates, oil lines, fittings, intercooler piping etc.

I think a budget build can be done right if you know where and how to cut corners. Most people doing cheap builds don't know what they are doing to begin with, so they just end up putting a bunch of crap on their car that's destined to fail. Even expensive parts will fail in the wrong hands.

Yeah, I'm in agreement with you. I'm probably going to sell this turbo to someone with a less demanding engine, like a civic, or a snowmobile. xD

I'll be picking up a turbo off Usedturbos.net Thanks for the link by the way.

How much are you asking for the turbo/manifold/wastegate?

Azriel, I told you several times that quality is better then knockoff products of ebay. You have a new motor that is built very well why risk it?

Honestly I think your better off to get a beater, and save for quality products or a good used single setup of this forum.

Just a Friendly reminder-The word "cheap" and "FD" do not belong in the same sentence......

I know Oly, I'm not going to cheap out on the turbo, but the other components should be ok.

check this one out... i did a quick search for good turbos and here is one of my favorites, if i had the money i would buy it!

http://hondaswap.com/parts-sale-trad...holset-378875/ im pretty sure a H1C is just a older HX-40 but it is still an awesome turbo

http://img49.imageshack.us/img49/3151/parts001.jpg

if you get it i know you will love the sound of the anti-surge housing... ive always loved it

search for FS: threads on other forums...

if it is a genuine holset (looks like it is) then i can almost guarantee you its a good turbo, and even if it has tons of miles they are easy and cheap to rebuild

Well that looks awesome, now all I have to do is sell this other turbo I have to buy it. Unfortunately, I'm without a car until I can put something together.

I may have found a healthy set of twins and an efini y pipe and intake kit for a steal. so I may hold off and do it this winter. If i can get a reputable turbo capable of 400ish HP for 400 bucks, i'll be going that way when the time comes.. thank you very much!

I have rdahm to thank. He gave me the out I needed. Most people wanted more for a stock set of twins than what I'd have to pay for a descent single turbo. Thanks man.

ninja Edit:

I more or less asked for advice on the turbo itself. given the specs it has, would a descent quality turbo with the same specs be good enough?

Committed?! You paid $200 for that turbo.

You'll pay about that much just on the misc. fittings to get it installed correctly, let alone all the real hardware, tuning, etc. You'd be better served, cost and hassle wise to throw that turbo in the trash, pick up some used stock twins for $300, and be running again a couple days later for $500. You'll NEVER get a single done for anything near that, and be luckier still not to blow your motor once you're done.

You later post says this is you daily driver, and it "just need to run". How long do you figure it's going to be down while you do a budget install job with all these mix-n-match parts? I've known competent mechanics with good quality kits who's cars have been down weeks and months for a single turbo conversion.

you can get braided oil line kits for RX-7's for 35 dollars. so that's a far cry from 200. I can get a brand new reputable turbo for 400 from what I've been told here. and the manifold I plan on getting should hold up fine with some extra bracing. So all said and done that's around 600-700 dollars.

The turbo swap itself might be more difficult if I didn't all ready have an ECU tuned for a single turbo ready to plug in, but I do. I'm confident I could take care of the mechanical aspect in about 4 hours. Then I would have to fab a down pipe, and build a screamer pipe for my waste gate. From there it would be a matter of fine tuning on the dyno, which i have access to at the shop where I built my engine.

I don't see it taking 2 weeks to do if I have all the parts waiting. Actually, it should be faster to install than the twins and all the stock junk. Perhaps they were waiting on parts to arrive that they ordered?

It will always take longer and cost more then you think. You will save a lot by doing things yourself, but if you're making the downpipe from stainless, unless you get it for free somehow the cost of the stainless fittings/pipe/bung/v-band and what not will cost like $100- 150 easy. Silicone couplers aren't cheap either, like $35 just for an elbow. Silicone hose, some kind of wastegate lines (stainless preferred) You can easily spend a few hundred in just miscellaneous crap you never even thought of.

As far as time goes, you will always run into problems, there is no way you will get all that out and back in in 4 hrs. You could have a stud stuck that takes you 4 hrs to remove. Always allow for error. Once you get it all back together you could end up with a funny idle that takes several hrs to figure out whats going on. Or an exhaust leak on a vband that just wont go away.

I would allow $1000-1500 when piecing together a budget turbo kit. I would be extremely surprised if you'll come out at $600-700 when all is said and done. I'm all for going single on a budget, (I did) but you have to be realistic about it.

Yeah, I get what you mean. It just seems like a lot of people want it now and won't wait for a deal. Or have money to burn and just buy what's there.

I'm confident I can have this done for under $1000. I have connections in the right places to keep the cost of a downpipe and exhaust fittings WAY DOWN. As well as access to a hoist and a welder and other misc things that make stuff way easier. Auto parts account that should keep odds and ends prices at a minimum.

I'll keep you all updated, as I may have some extra time with another set of twins.

id say doing a single kit (turbo, manifold, downpipe, and lines/fittings) it could cost you from about $900-$1300 depending on what parts you get. keep an eye on the FS section for manifolds and downpipes. the manifold should be easy but the down pipe could be hard.

the hard part about lines and fittings is getting the right adapters to suit the engine and the turbo, the lines should be easy.. seriously, you will need no longer than like 2 1/2 feet of stainless line

and before you buy a certain manifold or downpipe, do a little research and see what other people think about it, that have actually TRIED IT! i get that alot, people wont try a certain product but will say its worthless just because its cheap.. for instance i got my intercooler for $180 new (with piping, t-bolt clamps, silicon couplers, and the core) sure its not a $1500 intercooler but it works almost as good as one that costs that much.

a manifold i would definatly look at all options, they have to put up with alot of stress. so if you find one post it on here and do a little research on it. a downpipe wouldnt be something i would worry about breaking just as long as it is thick enough.

Ever ran a H1E? I had read that it spooled more like the HX-35 with the top end of the HX-40. I got one off eBay for $200 shipped, and we put it on another car to try it. We have no dyno maps or anything, but it didn't disappoint at all.

I had always shyed away from 40's bc of some old posts I had read about them not liking rotarys. Like I said old, things do change.

We have however NEVER had problems with the 2 HX-50 cars we have around here.

That and Holset rebuild kits are cheap as hell. I like Holsets. It would be (and will be) my "cheap" turbo choice. Though I have to do the cheap route bc I never have the money to buy one of the quality kits I want. I have to buy parts a piece at a time. I plan on spending $1500 to $2k, but can't all at once. And saving money for car ****, when my little girls want dinosaurs and princess stuff, just don't fly for me right now.

I hear that bit about your daughters. My little girl is having her first birthday in a bit over a week. So my priorities aren't based on my car .
