well, ive got my 91 JDM 13BTII engine in the condo basement, its all apart, and time to plan for the future, i talk to ppl with piston engine all the time, an they think the 1.3L Wankel engine can make 500to 600hp and if it dose it wont last 150000km or 1 day at the track, so im in a quest to build a nice 500 to 600 Hp setup and just run it at low boost for the street but, build something that i can let loose at the track, i would like to know if some one has built something close to those figures, im using a first gen body and i plan on using a ford 8.8" rear end.

i would also like to know if this turbo would be a good choice as its rated for 550hp Garrett GT3271

what kind of injectors should i use for pri and second,
what kind of porting should i use,

engine management:
i plan on using a magasqurt 2.0 system, with a wide band o2, and EGT's,

any input would be cool,
even if its a solid 450HP that would still kick the $hit out of most piston cars in london that are not using nos

 

You at least seem to have a good idea of what you're doing. 500hp is a lot, but I know it's been done before so that makes it that much easier, as this is the place to look for such builds. I'm sure there's a lot to this and if you're serious, make sure you document it here. Builds like that are always fun to read about.



What's a sentance? lol

Turbo is toooooooo small.

 

what about this turbo i found on rx7store.net
http://www.rx7store.net/product_p/garrett%20t04r.htm
Garrett T04R how much hp would it be good for? and i was thinking of using the .84 A/R?

 

As long as you do the build properly your goals are do-able. For driving around on the street you can probably run a safe 16lbs of boost and make around the the 400 mark, depending on what kind of porting you plan on doing. Ya might want to consider a bridge port. 500-600hp will be on race fuel only with pretty big numbers for boost, but it will kick ***!!!

Management: I am not sure if you can run megasquirt 2.0 on a rotary yet; you need to run the MSnS extra code and last I checked it was still only available for megasquirt 1. That being said, I am running Megasquirt 1 and it runs the engine fine. For what you plan on doing you should definitely think about going to a 3 or 4 bar MAP sensor as the standard 2.5 bar maxes out at 21lbs of boost (I think).

For injectors, nothing less than 1000cc's all around, maybe even 1600's in the secondaries. Make sure to upgrade the pump, maybe to a dual system and if I were you i'd probably run a surge tank too, just to be safe. All it can take is one lean mix and ka-boom!!

Running that kind of power the engine probably won't last 150,000, but that of course depends on how you drive it. If you drive it nice around town and save the punch for a few track days per year it could last a long time. As long as you do the fuel system correctly the car will definitely show well on the track. Just drop some coin on some C16, bump up the boost and let 'er rip!!!

As long as you do things right and don't cheap out espicially on the engine internals and fuel system all should be good.

 

No.

Personally i'm not too sure about the differences between all the different turbo's available but if you want a good street car and a good track car I believe you can't go wrong with a GT35R.

 

That GT3271 is not big enough. Look into any of these turbos: A-spec 500R, Garrett GT40R, HKS TO4Z, HKS T51R Kia, HKS T51R SPL, Garrett GT42R

All of these turbos can get you in your goal power range. A couple of those on the list will exceed your goals as well.

Also, invest in auxiliary injection.

 

^^^ You forgot to mention most of them will burn a hole right thru your pockets too!

 

you are going to need a gt40r or gt42r, standalone, some meth injection if you arent running race gas, completely beefed up fuel system, front mount, a clutch. 500hp is expensive.

get yourself a 20b and a gt42r and be done with it

 

thank for the info, keep them coming
its nice to have some stuff to work with and ideas i can go off of.

 

Go with a Ford 9" - not the 8.8.

 

GT40 will not break 600 at the wheels unless we're talking ungodly boost levels (i.e. above 30psi).

It's going to take at least a GT42 at minimum.

Were we not supposed to sit down and discuss your plans? 600HP on a 13B is nontrivial, and just plain crazy on a street car. 400 HP is easy.

 

The 13BT block in my opinion is not the strongest one, and seems after 540-570 rwhp everything has to be perfect. And no, perfect tuning is not enough. You need a standalone system with actual timing that is accurate. Mega-squirt, haltech, microtech are all time biased systems. I am sure others will disagree, but electromotive is the only one I would trust a high strung engine with. The timing is not time baised. This will allow for your dowel pin castings to live alot longer. S4 TII rotors, 2 or 3mm seals, GT42R, 900cc prim, 1600cc secondary, good port ect. will do it.

 

and what about the rest of the driveline?
isn't that going to need quite a bit of reinforcing, upgrading etc...

 

GT42 or Holset HX55, standalone, 1000/1680, dual fuel pumps, C16, really nice manifold and all sorts of custom piping, ignition upgrades, tires

basically I'd budget $12,000 at least.

 

for 600hp, a 42R.

I'd also reccomend a 13b-re over an S5 13b-t.

Youre also going to need a newly rebuilt transmission at the least.

 

i wouldnt recommend trying to make the 500hp feat, youll probably end up breaking yourself

if you want 500 hp, get a 20b or a 13brew, your looking at big dollars....

but with a 13b itll probably break
repeatably

to much boost for the little engine

 

So I assume you own a properly built 500hp 13b that always breaks?

 

He said 500-600 would be fine. The GT40R will do 500+ easy and has put down over 600 on a 13b.

 

Stupid........

The 8.8 is by far strong enough, while being smaller, lighter, and robbing less HP

 

Agreed... Check out Granny's speed shop for that setup. One of my friends has their 8.8 setup on his SA and it's EXTREMELY nice!

No one ever said that was going to be cheap! If you want to play you gotta pay..haha. I've seen your ride, I'm sure you most defintely agree...

If he wants to cut corners and not get the right parts for the job there's no way he will make the power he's looking for.

 

I'd like to see proof of that?
I'm talking about real Garrett models and not some frankenstein turbo like a custom GT4094...
Garrett only lists a GT4088R as a true "GT40R".
