wassup guys? been driving my 92 miata for a little while now, thought id join up on the forum.

ive taken the time since i bought the car to give it a full tune up and get some seat time in. changed the diff oil, tranny fluid, engine oil + a can of engine restorer, new filter, plugs and wires, and have been faithfully running 93 octane with octane booster(for *****).

Since i bought the car with 197k mi ive put on about 3000 miles, i noticed some changes in the accel after that work was done. its very responsive yet still skips when the pedal is tapped a bit, no big deal. im just waiting for the new b6!!

im enrolled to attend Ben franklin inst. of tech this september to start my auto career. im going to have a dyno and unlimited shop time so basically im set on getting all of the maintenance done now, and buying a clean b6ze motor/tranny and a stage 2 clutch+ lightweight flywheel. then i can drop a turbo setup in september, have it up and running beginning of november

i do have a question though. i noticed that some saab's and volvo's utilize a garrett turbo and i was thinking maybe it would be a decent t25 turbo to use for my miats. anyone have any opinions on the turbo? does it seem like a good idea? i was thinking it would be good for my budget considering it can be had for a little more than 50 bucks at my junkyard...i dunno. i have read that it spools up around 1,700rpm but thats all i know.

my suspension setup is going to remain basic for now; only touching the bushings, shocks and springs, and adding front and rear braces. nothing too low until i go somewhere without craters in the roads

thanks in advance for your help, maybe i can meet with a few of you guys up here in the NE at some point.

Welcome.

haha i knew it wasnt long until someone would've caught on to that.

my brothers "EASY" sr20 swap on his 240 lasted a year and some change...

anyway, do you think the saab turbo would be a good idea? know of anyone running a similar setup?

I personally have no experience. I would suggest doing a search about the topic. If nothing comes up maybe start a thread in the DIY section. Who knows, you may be the first.

Dude buy a used kit. Almost everyone and there mother uses some form of a T25 on here. I've had a Gt2560 and now a Gt2554, and a Td04-15G "Greddy kit".

You will be Dollars ahead with a used kit. And you can install it in a weekend. Otherwise be prepared to waste alot of dough figuring everything out. And not to mention time , $$$, time, $$$ and frustration.

Good Luck with the build.

And don't even THINK ABOUT A STUPI EBAY OBX MANIFOLD!!!!!!

Some have had luck with the cast ebay manifold. It uses a T3. They have a combo with the T3 and cast mani and wategate for best offer or $299 buy now.

If you go that way. Don't use the oil lines or mounting hardware. Spool will probably be late, but it should move.
That will be my next project.

does this include ecu tuning? not being sarcastic, because to be honest i know nothing about ecu's (i do know how to do everything else on a car but ecu's are a mystery)

ive read on the flyin miata kits that they come with a tuned ecu or something. is there a need to go tune it more if you dont have anything else done to the motor but the turbo setup? if i do buy a kit with ecu programming id expect it to work. lol

bare with me, if i dont learn now i never will. and im going to school for this so id hope to learn a little.

i did some research about the saab turbos on miatas, finally getting around to it. https://www.miataturbo.net/forum/t33740/


i would just take my brothers t25 from his sr20 once he drops in his disco this september...but his spools at 2,500 while the saab turbo apparently spools at 1,500.

if i were to have the same size turbo for both options, id think everyone would go with the quicker spooling turbo right? then again idk..

It all comes down to what you want.


Spool....
You have to decide what hp range you want.

usually higher hp turbos spool later. Where smallerturbo's spool earlier.

I have a 2554 right now. It spools super quick. Fast out of the hole. But a little less power than the 2560 when it gets going. But it supports up to 230hp. If you don't plan on going higher use that.

But when the 2560 comes in. It is alot noticably more powerful. Mine came in right after 3200 rpms. it was a beast. And is all around a great turbo. And leaves room for growth.

And you barely get the car moving and your full boost anyway.

Tuning,,,,,,,

You can pick up bandaids cheap.
YOU NEED A wideband O2 sensor and gauge.
You can get a bipes or msd for your timming.
And a Afpr for fuel.

It is fairly simple. Set it up and it only changes things during boost.

Now if you want over 200hp I would go electronic. MS, EMU, etc. etc. And they usually control timing too.

I have been down both roads. Learning to tune electronic can be learned. And is definately the way to get more power.

But you better be careful either way.

And If you want to start with bandaids go used. You can sell them later for the same price you bought them.

Have fun.

ok and one last question, for people that source out their own kits, what seems to be the most common setup? include manifold and tuning options.

also, how come people dont use the bp-t engine? i saw a scion tc drift car (the rsr tc) it utilizes the bp-t engine, with a toyota tranny or something.

thanks for your help guys, on a bunch of forums ive been to the past two years i feel that im actually getting somewhere lol.

Man I don't know what engine that is.

The miata's came with the 323 turbo motor from the factory. It can support 250hp safely. And some have pushed 300hp on stock.

Why change it.

250hp in a miata is crazy fast. My last one was insane. I never got to dyno it. But at 14psi the 440cc injectors would start to run lean.

Now I'm back to bandaids and never want to tune a computer again. I'll just run a safe setup. I only want around 200hp.

If your going to swap anything, swap in a V8. It is just sexy and seducing.

The BPT is the turbo motor from the 323/Familia GTX. There isn't really any point to find one of these motors unless you really want the sodium filled valves (I don't know if they all had these). The miata rods/pistons have replaced the BPT part numbers. If you've got one of the earlier miata motors you still have the piston oil squirters and oil/coolant ports in the block.

well put, thank you! and yea i got the 92 1.6L

a jdm b6-ze is definitely first on my list to change over before i get into school this september...then its tokico shocks and tanabe springs, 15x7.5 TRM c1 lightweight rims with some used tires, (im going to be using this car as a weekend drifter/daily driver, might transfer to scca solo 1 next summer,) rear sway bar, front under brace, energy bushings, and then i can get the process going on the turbo setup.

i am very ambitious about getting this car up to where i want it to be. money wont be that much of an option i hope, and shop time is unlimited, hopefully my scholarship overpays my school

thanks again guys

Thanks.

Just curious why are you sticking with a 1.6? You could do a 99/00 motor fairly easily. The VICS wouldn't require a different ecu like the VVT motors. After watching a 99 put down +30hp (with an intake and exhaust) more than I did, at the same dyno day, I've been wanting a 1.8.

It is just to easy to turn the boost up. But different strokes for different folks.

-Banks-

haha well honestly i havent been researching the 1.8 motor as well as i should be, ive just been told how easy it is to turbo a 1.6, but ive also heard how much of a pita it can be, nothing of the 1.8 swap...

all i really have on the 1.8 swap (which i just found out) is that you theoretically could use the 92 ecu for it, but it wont run the VICS. id have to install a MSD RPM switch (#8950) to activate it. thats seems like the best option since everyones doing it lol.

I'm not trying to talk you out of turboing the 1.6, I'm about to do it.

Just figured if you were going to be swapping motors already, why not, if you can pick one up for a decent price. Turboing a 1.6 or 1.8 is about the same $$$.

-Banks-

oh, i know that. when i said 'it seems like the best option' i was referring to using an rpm switch (or even megasquirt pnp i believe) as means to run vics.

so instead of getting a jdm b6 i should just get a 1.8 (they are called bp's right?) and the rpm switch. are the 1.8's good with boost? i know absolutely nothing about them. and i suppose the b6 tranny mounts to the 1.8 motor?

just wanna know so i can compare pros and cons of both motors

Yeah all the 1.8s are BPs. Some of them have different compression ratios, I can't remember what they are. You can probably find it on here somewhere. There are lots of example of boosted 1.8s and 1.6 around, it is the turbo miata forum.

Transmissions all swap, the newer ones have a slightly different starter mount, but you can get around that. If you end up swapping difs you'll need the 1.8 driveline and axles.
