First of all, I did search, and I found nothing pertaining directly to what I want to know. What is the proper way to turbocharge the 13B 6 Port and run about 225-275 flywheel hp? I know I'll be getting replies saying to sell my car and buy a TII, well that doesn't work in central Texas. I haven't seen any on AutoTrader.com and there is no chance of stumbling upon one on the side of the road. Now, lets just talk about adding a turbo to a car- lets get to the nitty gritty. Obviously the following will be needed for it to work: Turbocharger, turbo exhaust manifold, turbo intake manifold, intercooler, drilling/tapping of oil pan and run lines to turbo, larger injectors, better radiator (thats about all I can think of for now). If this is all that needs to be done (and if it isn't, correct me), what can I do to make it all work together? Would I need to dismiss the MAFM and O2 sensor and run a standalone? Would I really need a TII tranny for a low hp number? What is necessary. I need someone to help me out a little because I'm not even sure. Thanks.

You can't put a turbo's intake manifold on a non-turbo engine. You have to work with the stock manifolds and make a spacer for the manifold to clear the intake manifold. I'd recommend going standalone with some upgraded injectors, and I'd also suggest upgrading to the TII transmission (and rear end if you have the money).

You're wrong.

dont just tell him hes wrong explain it for him

just telling him hes wrong doesnt help anyone

That's pretty much the complete way of how to do it while keeping the stock n/a manifolds. You can change some things if you have a better idea, but that's the basics.

Fine.

Get the lower TII intake manifold, put on a 6port gasket to see where the single side ports need to be ported to. PORT THEM, wow all of a sudden it works. Basically you just port the side ports on the TII lower to fit over the 2 smaller ports on the block. You can then make a divider if you want, but honestly I don't think it'd matter. Then with the TII lower you can use the upper and TB just fine along with the stock top mount if you want to use that as well. You'll now need a TII hood. Also you'll need to get the TII throttle cable. When using the TII manifolds you would not need the spacer, either, and can just put on the TII exhaust manifold/turbo just fine.

To fab up the flange its about 40$ worth of parts from racingbeat.com. All you need is an arc welder and a steady hand, I think its pretty easy in my opinion, but yes it is required to clear the LIM for the turbo.

Kevin landers just did a write up on NA drivetrains and how much power they can hold. Do a search on posts by rotaryresurrection. As far as the rest of it, IMO it's really easy until you get to the fuel management part of things. You can make a t2 LIM fit on your block which will allow you to mount the turbo without a spacer. Mazdaspeed7 did it and has pictures of it. Look up his name for posts. There is a racingbeat oil pedestal tap for oil gauges, you can use this as the oil feed for your turbo. Then you just need to make a return to the oil pan. I'm not sure how you would handle the wet side of the turbo, check with aaron cake on how he got coolant to the turbo? I suppose you could run very low boost w/ an AFC and get maybe 200-220hp. I don't think you are going to get as much as you want out of a 6port 13b without spending more money then you would on a motor swap. More then that and you will need to start looking at a full aftermarket EMS or piggyback fuel computer.

That's interesting, I never thought about adapting the Turbo II manifolds to the NA block. Seems like a lot of trouble, though.

First off, it's BS that you couldn't find any info on this topic. I'm not even thinking of this and I know how to do it because I've read most of the topics i\on this subject (turboing NA).

Holy misinformation. God damn, what do you mean you couldn't find anything on how to do this? There are so many of us running 6-port turbo's it's sad, as for 'proper', that depends on who you ask. I'd consider a proper setup one that's reliable and works, which is basically anything. I'm running on a BNR stage 3 on my 6port with just an s-afc and a wideband. It all relative, there's not really one specific way, you have to set a goal, organize what you'll need to reach it, then think about what you might want to do once you acheive this goal (such as ability to up boost/more fuel/better intercooler/tII manifolds/better turbo/etc).

snub: it's actually pretty easy, this is what I'm using as my manifold on my supercharged GTUs, a ported tII LIM bolted to the 6-port block.

Yet another way to do it.

wtf

snub disphenoid

I was trying to say that you have to space the stock exhaust manifold out to get the turbo to clear the intake manifold.

edit: manifold. singular.

exhaust manifold

That link to nopistons was really helpful, thanks. Oh, and is it really that cheap to get it up and running? I'm not planning on running 12psi, I'm thinking more like 6-9psi. SonicRat, I've seen your setup before and I like it. I did search and I got lots of irrelevency due to my incorrect wording or something, but I would really like some help from you on this.

Whatcha need?

1RevvinFC3S

Info, lots of info. I'm a noob when it comes to mods and fabbing and whatnot and judging from what I've seen about your turbo'd 6port, you seem to definately know your **** because that car owns. I'd just like some info, a parts list, and an overall estimated price for the whole thing, know what I mean? I'm coming to you, not because I'm too lazy to figure it out on my own, but because I can't afford to mess up on my daily. Like I said, I'm not looking for insane boost and killer horsepower numbers, just something that would be reliable and reasonably quick.

Well, it depends on the ways you want to do it, porting a 4port manifold would allow you the use of a stock intercooler in the stock place, but this is a bit more costly to replace all of your parts/etc. Anyway, here's roughly what I did:

Two racing beat flanges, with some thick steel tubing welded together to space them 2.5" (outside to outside), two exh manifold -> engine flanges, and whichever turbo you like. That will get your turbo bolted up (you'll need to find some bolts/etc at the hardware store to hold it all together). After that, you need to figure out an oil return, either pop off the oil pan and drill a hole in the front cover and tap/run a hose barb to it, or swap the front cover with that off a tII. For oil feed, i just drilled/tapped the oil filter pedistal and put a 90 degree elbow on it with a 1/4npt hose barb, and used some high pressure line to run it to the turbo's oil supply (which I used a compression fitting and another 1/4npt barb for). Coolant I just used the line off the back of the waterpump and directed it through the turbo and into the nipple on the back of the block. Now we've got the turbo mounted, oil, and coolant. Now comes the time to mount your intercooler, if you maintain the N/A setup, you have to frontmount it, I went with a starion because I got it for $50, and slapped that up front, I used some thin exhaust pipe for all my IC pipes, since I was in a hurry, couplers are upto you (i used sillicon), then buy a BOV kit and weld it onto the pipe and you're all set there. Make your own inlet duct from whatever you desire, it's nothing special. Some people have problems with the wastegate hitting the frame, to get around this, unbolt it and unbolt the oil cooler line, once the turbo is mounted, bolt on the wastegate, then bolt on the oil cooler line, and it should fit (and possibly BARELY touch the frame, but it's fine) You can also hit it a few times with the hammer for a little bit of extra clearance) And then you're all set to go, get a custom DP made (local exhaust shops can do it pretty easily). *PHEW* Any questions?

Oh, some hints:

S4 Turbo is a better fit! The s5 hotside is too large and hits the frame! (if using N/a manifolds)

1RevvinFC3S

Hmm, that actually sounds relatively simple. Is the S4 the same as the S5 (Hitachi T-18)?

SonicRaT

Same turbo, just different hotsides

Title updated... Please put the question or topic in the thread title instead of the newbie style title this thread had.

And dammit man, search and use the FAQ for FC. Every question you asked was covered in the FAQ for FC sticky threads links.

I should close this thread just on that

1RevvinFC3S

I searched but some irrelevant crap came up. Honest. I probably searched wrong but I apologize either way.

Icemark

Well maybe this thread can help others out then... thank you for searching... and don;t forget to read the links in the FAQ for FC on this. Arron has a great write up linked there!
