: Looking to Piece together a Turbo kit for me SPI
06-14-2010, 06:32 PM
After looking around a bit, i thought it might be a little fun to turbo my little SPI, mostly because it would give me the biggest results. Now, I have searched and searched, and I have been told the SPI doesn't handle boost as well as the zetec, which is understood, but I havent seen any actual contestants to the results you can get from turboing the SPI. so I have a few questions.
Has anyone here turbo'd their SPI?
and what types of affordable but effective parts should i be looking for. Since it wont have to handle probably more than 10 PSI max, the turbo wont have to be anything fancy. just reliable and small.

There are a few people have turbo'd the SPI, but just doing a quick search, I don't even see SPI turbo manifolds for sale. It's going to take some ingenuity and some custom parts, unfortunately.

there is one for sale right now inthe BST forums and its pretty cheap!

dang, just beat me!

Do you have any power goals? That will get your foot in the door on choosing the correct turbo. T25 turbos off Nissans or a VJ17 off an older Tbird coupe would get you some positive results for a fun DD build.
You don't have to go too large on your piping, maybe 2" or 2.25". Get an intercooler that will fit in front of the A/C condenser.
Make sure you get some decent flow injectors.. 36, 38, or 42lb would be good. 42 being the best since you have room to expand. (~275hp)
Eh, those are a few basics. You'll need an oil feed line as well as a oil return. You need to tap your oil pan for the return.
Get a boost gauge and a wideband for tuning.
There's a lot more than just this, but those are the basics..

Spyder, I saw that one and actually talked to him. Its a matter of myself getting the cash together, but the way things are going right now, I worry it might be gone by the time I actually have the money together. Also I may be a little naive for saying this but I would think a well known brand turbo would run better than an ebay turbo.
I don't want to put too much stress on the engine seeing as it is has to be usable as a DD for a few more solid years, but I would love to track it in the long run. Like i said, I'm having a hard time finding numbers on the gains seen on an SPI, so i don't know what kinda of numbers that are reasonable or that i can expect.

Ask that guy if he will do payments. Buying that kit is by far your best bet. Plus you can always replace that Turbo with a brand name one of the same trim. It would be a nightmare to try to piece together a kit for an SPI.

^^ Agreed, it is at least a great start.
Although I dont like buying used kits.
Start pricing out stuff and you will realize that is a bargain for many of the basic components that you could later swap out if you needed.

900 for that kit is a steal.
06-15-2010, 03:14 AM
I agree with these last 3 guys. $900 bucks and you're way ahead of the game. Trying to piece something like that together will be a PAIN. If anything, you can change out the turbo.

alright my mind had this issue before too, but for some reason threw it out. I honestly cannot understand this. the picture of the downpipe has that extra pipe coming off that attaches to the compressor side of the turbo as well. wtf is going on here. this is how im picturing it. the blue is the air from the compressor.
so all the air, even the clean air is being blown out through the exhaust? someone tell me im not the only one who sees this.
06-15-2010, 08:40 PM
Not quite sure what you mean. If you are talking about the pic of the dp where there is another pipe coming over, that is for the wastegate to dump back into the exhaust.
06-15-2010, 11:13 PM
well then i guess thats what i mean.. sorry my brain was thinking part to part wise, and it looked like the compressor was blowing right into the DP.
06-15-2010, 11:14 PM
Jeff, I know what he means.
The downpipe doesn't flow air from the compressor, only from the turbine housing. The pipe coming off of the downpipe is the wastegate (the silver thing to the right of the compressor) recirculation. No air from the downpipe ever touches the compressor. That would be bad mojo, obviously. It looks like a really nice, thought out kit.

yeah i understand it doesn't. thats why it confused the heck out of me.
I have a few friends I could probably rely on to help me install it. if not there are some mechanics in the family, but for a logically minded person with some mild guidance, how hard of install would this be? I know i would need oil lines, but what kind of ECU tuning would you guys recommend?
^^^multiple answers appreciated :D

does all this apply to any turbo kit? even the ones that come "complete" from a company?
06-16-2010, 01:04 AM
The FSWerks kits will include oil lines. You will still have to get your oil pan tapped for a drain, though (meaning it has to be off the car). I got a new oil pan and had a bung welded on so I could do the swap quickly.
06-16-2010, 01:01 PM
so a elbow fitting screws into the pan? what about the wideband, is it hard to tune without one of these?
06-16-2010, 01:17 PM
you will be able to tune it on a dyno without a wideband as teh dyno will have one built into it. but if you are doing any sort of remote tuning a wideband is needed. as well as suggested for anyone with extensive engine mods
06-16-2010, 01:58 PM
& what wideband would you suggest thats affordable?
06-16-2010, 02:44 PM
AEM makes a great Wideband. Depending on where you get it from they go for around $200.

aem is a good choice, the Innovative LM-1 is another good choice although i believe it costs a little more
06-16-2010, 10:12 PM
that was actually, when i searched, the first one that came up. the LM-1 that is. but what kinds of information do i need? just the Fuel to air ratio and boost?
06-16-2010, 10:46 PM
Yeah, those are the important basics.
06-16-2010, 11:50 PM
ya that is a great place to start, also be sure to upgrade your oil when you go boosted, most turbo cars run 15w-40 oil...
the lm-1 is a nice unit and has very good reviews. it has alos been out forever without any bad things going on with them
06-17-2010, 07:12 AM
Upgrade your oil???
You should not change your oil weight just because you go turbo. Run what's in the owner's manual. A turbo doesn't change the characteristics of your engine.
