Default gt2540 viability

hey all, Im trying to throw a gt2540 hks ball bearing into my 97 1.8. Will this turbo fit well? or is it too big or not a good fit for the car? I haven't seen really any threads about this turbo setup on miata, but this is what I have to work with and it is a good turbo so I am going to throw it on. If anyone has any tips before I tackle this project that would be helpful.

I'm looking at this manifold

I also have the old miata link setup but I've heard its not a good idea to use so I'm thinking about just DIY a Megasquirt 1

on the other hand I don't want to spend money and time on Megasquirt but I have heard many good things and too many bad things about the link setup. Yet I do have the link setup ready to go.

My brother has a few intercoolers to spare and i'm going to see if they could fit but any input on something cheap would be cool.

I was pretty much gonna buy one of those cxracing piping setups from ebay to throw it all together.

I am on a super tight budget so i want to go zoom without ka ching. So really do I need to ditch the link setup to run with MS? I know engine management is the key to running a good setup so any input on that side would be good.

I know I will need some gauges and or wastegate and blow off valve? any input on these things would be helpful for which are good to buy. otherwise im prolly gonna buy the cheapest thing i can and blow up my car....

I guess i should just ask if the turbo is viable or not, anyway it doesn;t really matter i may as well delete the thread and build it without any input. I just can't find thread with this turbo.

Is there a reason why nobody uses this turbo? its too big it will blow the engine? too much lag? won't fit under the hood?

I want to be able to drive up a mountain faster, faster take off and straight hp.

the miata is fine in turns out of turn etc but hard to pass other cars in my area

I will build up the engine if I need to but I have low mileage and am running strong

i don't want to run nos as I want steady increase in HP since i am driving around hills and mountains and need to have power in turn. also i am not blowing my engine up as I am going to run blow off wastegate and intercooler and may add water injection but nobody seems to have input on these things anyway except to run NOS maybe i'll look into it...

I ran this turbo. I was gonna comment more, but I was appalled by how retarded and lazy the rest of your post was so I didn't.
Good luck with the ebay manifold. Those have an amazing reputation for reliability.....

Then you have a lot of learning to do. Going fast on a budget is doable, many have done it. It's a great way to turbo your miata. But to do it on a tight budget will require a lot of DIY work, finding good deals on used parts, tuning it yourself, building parts yourself. All of which will require you to do the reading and research to learn how to do all of this.

That turbo is small but it's not bad, and if it's in good shape it will work fine on a miata.

if by small you mean big enough to easily vent a bp block, then yes it's small.
it's roughly disco potato size

A 2540 in HKS land is bigger than a 2554 in Garrett land?

Sounds like you have a Garrett turbo in the GT Series GT2540R also known as GT2876R, A/R 70 front cover with a .64 or .86 rear wheel, I have the .86 version myself. They are classed in the GT25 range and part numbers and specs are as follows

Haha you're probably right. I misread it as GT2554. If disco potato size then yeah, good size turbo for a miata. Build it OP.

I appreciate some more thoughtful posts. If the ebay manifold is not reliable I will buy one that is a bit more reliable but I don't know where to find one, I am guessing that my gt2540 is the same flange as the T25? So I can just shoot for a nice tig weld manifold that is for t25?

I am just asking for opinions how does it matter if my post is lazy or not. If i get a lazy reply i can make a lazy post.

My car is pretty much set to run turbo. I haven't rebuilt any engine parts but I have a full 3 inch maybe 2.5 exhaust from corksport but am replacing the resonator and muffler tip and putting a highflow metal cat in this week.

Also put in the flying miata happy meal clutch. I put in Bilstein shocks in too that has helped out with handling.

I have the link system ready to go and have the charts to tune with it but I don't know how reliable that may be to use.

I am just looking for more tips before i go ahead with throwing this turbo in because I have no idea how the manifold may fit with the turbo if it will stay inside the bay or something.

I am happy with DIY the parts or making stuff. I also have some shops around here who are happy to take a look at my work if I have any problems as they are experienced with this style of DIY install.

I would just appreciate some suggestions on other parts to buy as I already have the turbo in great condition no shaft play and its ball bearing so I am really hoping to have this turn out well.

I'm not going to cut corners on it but I don't want to buy stupid parts like a hydra plug in or something for crazy amount of money. I need some input on wastegate and blow off valve, manifold, piping (yet i heard cxracing is good and I like the prices). I want to go ahead and get all my parts ready for install because I am on a budget I need to know what to look for and buy what I need when I find a deal on it. I am not sure if I should just not post ever here because its not too helpful or not but I am trying anyway.

I am just looking for other people who have gone through the mess of making these turbo work cheaply. What parts would I need to build myself? If ebay manifold is that bad okay its like saying never buy anything from ebay. I've brought broken **** off ebay and with a little work it works great. Idk about exhaust parts but literally they are just metal tubes. maybe one is thicker than the other different kind of metal but if its the right metal right thickness Im not sure why it would be bad to use. I will look for one that is a bit beefier but I don't really know where to go for turbo parts on a budget except the big companies.

thank you aidandj for that link

<p>You are being called lazy because everything you ask has already been answered. Reading and searching will answer everything you need to know.</p>

Read, do your own research. Nobody here is going to spoon feed you. In fact my post is about all the spoon feeding you're going to get.

thank you aidandj for that link
Have you looked at any of the stickied posts in any of these sections? Have you looked in the build thread section to see what other people have done on a budget? Seriously click the advance search button in the top bar, search for budget build in the build section, start reading.

thanks i do enjoy reading other peoples threads that have been flamed as is mine, but really i just want opinion on getting a manifold since that seems to be the major problem here, I just wondering which flange to get I can't tell from reading if it is T25 or T3 as it is really not clear or they are the same? I don't want to put an adapter on it if someone can answer that would be cool but i'll just read and still not find out since I can't find people with this turbo in their build..

every thread i read is just flamed up for being a budget build. I am not looking to build as cheap as possible I am just looking to build my setup. Cost I like to get a deal on everything so I don't like to buy new expensive stuff as I am in the mind it can be had for less. If people don't want to share experience on a community board it just does not make sense to me.

I can search search for threads and not find what out what I need and people can say read more read more all day. but in the end it just makes everybody's threads the same. They all say read more read more do the research yourself. Maybe in the 5th page of the thread I can find something out but really it is difficult to find good quality threads.

It just seems pretty ludicrous that people who have successful setups want to make people waste more time to build one so that in the end there are less turbo miatas out there because someone wants to make others take longer to find answers. I understand that people want others to not ask stupid questions but really it gets dull to read the same **** in everybody's thread. I am here to build a turbo setup and have a few answers to a few stupid questions so that I can get on my way because I am tired of not having a turbo in my car.

I appreciate the thought of searching budget build as I couldn't remember reading that somewhere on here in someones' thread like mine. but I am not truly building a budget build just have little money after install my clutch and exhaust. If i need to get extra money to buy something I will. If people have bought parts I think they should say I have this and I am happy with it, not that part is terrible blow up your car with nos.

I have read and read, and I of course continue to read and read but its nice to have my own thread where I can ask experienced people instead of reading threads from 2005 where everything says its outdated. Does that mean I should do that setup? I'm not sure maybe there are newer parts or threads. I'm reading i'll say that much but in my mind, I see that I need this part this part and this part. I need to attach it to my car. I need to tune the engine and then drive. the only part I really need help with is buy the part. which part i'm not so sure since nobody will tell me. apparently being spoonfed is getting someone to recommend parts because they want me to blow money first then come back and talk about how i blew my money on parts

Search the build threads of every member that's posted here. 18's is a little long.... But the others are probably readable. Search my name I did a DIY turbo setup back in 2008 or so, it was fairly cheap and DIY oriented. There are many here, and they all have something unique and awesome about them you can learn from.
