No, the Turbo has lower compression.

The 87-88 Turbo's compression is only 8.5:1 while the 86-88 non turbo motor was 9.4:1 compression.

Even the 89-96 Turbo's compression ratio was only 9.0:1 which is lower than the 86-88 non turbo engine.

And you still didn't say who was building the motor to make 400 HP. I hope you are not thinking that you will just bolt a Turbo onto a used high (or even low mileage) non turbo engine, and you gonna get 400 HP.

 

Yes it can be done. But that doesn't mean a 400hp rotary with high comp. rotors will be easy to use.

You need to do a little more research.

Running that kind of power with a higher compression rotor setup is going to make tuning...and driving for that matter....on the edge of a knife. Sure guys with a piston engine run 9.0:1 pistons and boost them, but you can also detonate a piston engine from canada to mexico with little or no problems other than the blonde in the driver seat wondering what the ping sound is. Rotaries are an ENTIRELY different ball game. One ping can pop the motor.

 

Damn, this sucks, where do I go from here? How can I get 400hp now

 

Would it work or even get me close with a smaller turbo? Or can I just not turbo this engine at all?

 

Well all you have to do is go buy....

1: J-SPec TII engine, and rebuild it
2: T4 flanged manifold
3: T-78 (I guess....thats what you want.........)
4: Wastegate
5: Frontmount
6: 550 primaries and 1680 sec. or another combo to net the same overall fuel amount
7: Adujstable FPR
8: Fuel pump
9: Clutch
10: EMS....Id recommend Haltech, but whateva
11: Wideband
12: TII drivetrain
13: Koyo rad
14: Whatever else you need to put that together such as oil feed/drain lines, fuel line, etc.
15: A good tuner and a prayer

Its a big money game to get into.....trust me, Im ****** broke and Im still tyring to get my **** to the dyno!!!

Edit: you "can" turbo that engine, but if you're really shooting for 400whp, you will have a tough time keeping the N/A block intact....or I should say...you'll have an easier time keeping the TII keg intact.

 

Can i swap bigger ports onto the s4 turbo to take care of the small ports problem?

 

rather than drag this thread on for days...............

there is plenty of info on how to make 400hp out of one of these motors...the S4's "small" ports aren't a problem at all.

Do some reading in the Single turbo section, search 400hp in there and see what you get.

 

Who saind anything about running higher boost?
If we're talking big turbos, it's all about flow...

I guess you missed the part about narrowing your safety margin with the higher compression?

Look, this was my assumption on this thread...
The original poster has no clue what they are doing.
This has been proven with their ignorant replies.
You're going to assume they can tune a high compression 13B to make 400hp?
Boy, you got a lot more faith in others than I do...


I'm not worried about the engine.
I'm worried about the blast non-turbo intake manifold...


I never said it was impossible.
I said...I think it's a better idea to use another motor...other than the stock non-turbo 13B.

What the hell does this have to do with:
1) FC's?
2) rotary engines?

hey dude, i feel for you, im trying to make 320hp on a tII.
its a rough road.
have you thought about a super charger?
camden..(correct me here, guys) makes a nice super charger for the NA 13b.
i know ive seen someone on here showing a thread on bolting it up and everything.
it may be cheaper to rebuild, port, 3mm, supercharge, and all that good stuff
if you already have the 13b.
you know, just thinking outside the box.

 

Yeah i give people the benifit of the doubt, so i probably have to much faith in others. But if the guy wants his 13b 400hp high comp to work i'd like to him some options he has instead of telling someone the risks first to scary him off(not saying that you are, just generally speaking).

In my project wich happens to be also a ,13b n/a high comp turbo setup, the stock manifold is going to be replaced by a custom piece so i'm not worried about that. It's good to know that the intake manifold is a weak point according to what you're saying.

Yeah i wouldn't recommend the stock 13b as a base setup either, but if it's rebuild and beefed up the engine can be as potent as any other. (My oppinion). We'll see what my project does when done. It's going to take a few months but it's progressing good.

That had the hell to do with the point i was trying to make by high compression and turbopower. It had nothing to do with FC's and Rotary engines. You missed the point i was trying to make, or i wasn;t able to make my point clearly enough.

Keep your shirt on guy no need to start bringing hell into a healthy debat. It's a forum, and i'm still learning about Rotary engines
