Hey I was wondering if you can put a turbo on a 13b?

 

Dominic,

The short answer is yes, you CAN install a turbo on an NA. For the more detailed answer, please use the SEARCH button located above. This topic is covered in a number of threads in the 2nd gen forum.

Thanks, and welcome to the club!

Now this is a very decent reply, he didn't crawl the guy's but.
thanks

 

Wouldn't he have to run lower boost because of the high compression? I always thought that it's better to run lower compression and higher boost.

(For example you run 5 psi safely on your high comp. stock motor and make an extra 35-50 hp,
when you can safely run 10 psi on a 13bt and make 100 more horsepower)

 

What do you think the compression ratio is at on a 13b?
Thanks

 

Also would I have to change the intake manifold and the throttle body

 

86-88 N/A 9.4:1
89-91 N/A 9.7:1

I assume you have one of these two engines currently.

 

Technically, no. But it really depends on the setup you want.

It is much cheaper just to buy a TII - generally.

 

Not necessarily. It depends on the type of performance, the fuel's resistance to detonation, etc, that you are looking for.

 

Yeah, you can turbocharge the 6 port motors; I'd reccomend finding one of the low-comp 4 ports and using that instead. (13BT, 13B-REW, 13B-RE, 20B, ect.)

Lower compression=less chance of detonation because of less heat of compression. It means you can safely run more boost.

 

So you're basically saying that if he is willing to sacrifice performance and/or use race gas, then it's ok to turbo a high compession 13b.

 

i have run 18psi on my 9.4:1 stock 12a on pump gas. fuggin pwnz i normally keep it at 14-16psi every day use. no detonation and hell... i even use a carb WOOT!

alot of the bs around high compression and turbo's is all built up on "hearsay". someone reads that it's bad, so the next guy reads that some guy just read that it's bad and tells the next.... blah blah..

yes the higher compression needs the eye on tuning to keep things in check, but pump gas and high boost work fine. if you are only wanting lower compression for it's "less chance of detonation" then you don't need a turbo car

soooo for a simple answer as stated above... YES, you can put a turbo on your n/a very simply.... and it works very well. JUST REMEMBER TO TUNE!!!!!

 

what he said. you can go with a tII block but what's the fun in that?!?!? heh heh, anyways, you really have to be careful on tuning the motor. people here say it's best to run a standalone ems this way you can control the engine better but it's pretty expensive. some people here got away with using the stock n/a and tII ecu's. the only way to make it reliable is to make sure you have proper air/fuel mixture under boost, and timing. look for aaron cake's website. he has lots of info on how to do it. also, if you're looking to make high horsepower, have a tII tranny and rest of the driveline in hand.

 

Yea I've looked at his website, I don't what I should do because I want to run a T4 in it.

 

t4's are bigger than the stock?...if so, then you cant use the n/a intake. you'll have to change to either the tII manifolds (cheaper but have to port match the auxiliary ports) or custom intake (more $$) and you definately have to go standalone

 

well I think i'll start looking for a 13bt and do it the way I originally planned.Upgrade the turbo.

 

Can someone please explain to me why every manufacturer in the world drops the compression on their motors significantly when they turbo/super charge it? I know that more compression = more power and also that high compression high boost motors can be reasonably reliable with extremely good tuning and may even reduce turbo lag but what I don't know is why everybody drops the compression and raises the boost when they want to make a large amount of reliable power. And the dude running 18 psi daily on the 9.4 compression rotary : You are the man!!!!!
Unfortunatly those of us that don't know any better are running 9:0 with 15 psi max to make 400 wheel horsepower that will last for many years and thousands of miles. I wish I had the technology to run 20:1 compression and 99 psi so I can be super reliable~

 

Manufacturers drop the compression because they dont want to have 1000000000 warranty claims.... They want decent gas mileage and in mazdas case, keep the 87 rating...

Running higher compression means running less boost but more power/torque... If it makes more power n/a, itll make more power turbo... not always the case, but general idea behind high comp boost...

 

.

 

HOw is he sacrificing performance??? 13 na will make more power at lower boost levels..

 

they drop the compresion ratio to make the motor less prone to detonation, which also makes it easier to run more boost.

 

Thanks and what I meant is that you sacrifice performance by limiting the amount of boost you can run. Why not limit the compression and be able to turn up the boost. I already understand that more compression makes more power but 10:1 @ 10 psi is less compression (power) than 8:1 @ 20 psi. No?
