Any suggestions?I know I'll need some 1600cc secondaries and huge IC and fuel system to match it but I want to know what turbos are out there that will produce 500hp at the flywheel?



Thanks

on a rotary you need a To4R or bigger, you can do it with a To4S if you don't mind boosting the living **** out of it. There are several large ball bearing turbo's you can use but I wouldn't ever run a ball bearing turbo on a rotary engine unless you've got $ to burn...

I kinda figured that the T04R would be the best one.I plan on a non-ported 13B-RE or 20B-REW and my power goal is 500hp next time.Damn turbo will be costly.I can boost the crap out of stock twins for awhile I guess. https://www.nopistons.com/forums/pub...#>/biggrin.png

Then save up and build a ported engine. :squint:

you may be into boostin the stock turbos for a while, but too much heat from all of that boostin will cause some premature wear in your other components. get ready for a **** ton of money.



the goal that you seek is not too far fetched at all. that is roughly 430 whp. so, any turbo like the T-78, T-04r/z, GT35/40, T88, and T-51kai will all surmount the goal that you seek. just make sure that you build towards that goal, not to it, and then learn the hard way.



just look at all the guys that are poppin seals out the ass b/c/o irregularly proportioned maps and tuning curves. there are far too many horror stories out there for me to make a jump right now. ****, i have 4000.00 in cash in my bedroom, and have been looking into singles for a year now, and am just making up my mind. and because i am shooting for 500~hp and a daily driver most of the time, i am going with the gt35/40. i like the to4r, but i am looking for the most easily installable turbo kit that i can purchase. so, those were just a few of the things that were affecting my decision during the search.....of course, i now have the ported and dowell pinned motor with HD seals and fuel to go with it....





good luck!

OK,Thanks for the help.I wonder which is best for the $$$?I think the T04R is prolly the cheapest one to buy.Either way I want to build it and do it right on the first try.Thanks Louis

i'm also doing a 13b-re swap...and those stock turbos are good for around 14psi...what you might think of doing is sending them out to bnrsupercars.com...they have exp with that turbo set up.

the to4r is not going to be the cheaper of the kits, in fact, hks products are some of the more pricey ones to be had. just do as much research as you can, and take your time, and make sure that your car is ready and up to the task....

Yeah I know all about that.When the time comes I'll see what my options will be.I'm really thinking of a 20B single turbo FB. :yum: https://www.nopistons.com/forums/pub...#>/BURNOUT.gif I'll try to get the car in the summer while saving for a T2 tranny, lightwieght flywheel, clutch and counterwieght.Then buy winter I should have the money for the engine.Then at least I can see the clearences and get a idea of what will fit.Do you which of those three turbos is the best for the buck?I hear reports of FDs pushing 500 on the T04S at 14psi is this also possible?



Thanks

Luis

I was considering doing that but I think a 3 rotor FB would be a nice car to own.Just think of the torque on a lightwieght car....... :yum: https://www.nopistons.com/forums/pub...#>/biggrin.png I need to get a Haltech E11 to run it but thats the price I'll have to pay.Just like running dual oil coolers.Parts will be around $16000 cdn when its done and ready to run.Should take me a 1-2 years to build it but I don't mind this 83 rx will be used more than a 20B anyways.Damn 20B's are gas hogs. https://www.nopistons.com/forums/pub...#>/biggrin.png I'll have a full kit and spoiler for it planned out when its running.Got to have the show to go with the go.Then some nice 16's would suit it nicely.

I would guess stock 13B-RE turbos need a lot of work to make power. I think my quarter shows that https://www.nopistons.com/forums/pub...DIR#>/wink.png

hahaha.Those stockers a small.I wonder if the 3 rotors twins are that small?I will start the engine with them just to use for awhile till I get a T04R.Then I'll have my flywheel horsepower mark.Then I can make it look apart from the stock bodied first gens around here.Hopefully theres enough room with dual oil coolers and rad moved forward to support a big IC.

Why do you want dual oil coolers? Why not just one big one?

Attention 13B-RE guys. . . https://www.nopistons.com/forums/pub...#>/biggrin.png



I spoke to Dave Gibson the other day just talking about a bunch of nothing in particular. We got on the subject of what turbo I should move to on my 13B-RE. He said that a tuner he knows out in Cali took an RE that he got from Dave, took off the emissions crap, and tuned it with a Motec EMS. He cranked the boost on the stock twins up to 14 psi. How does 508 at the flywheel sound? :bigok: I'm sure he was pushing the crap out of the turbos, but DAMN!



I got a warm fuzzy feeling when I started thinking about my 60-1 on that motor. LOL.

:eek: Thats a lot on twins.I wonder how long till a melt down? https://www.nopistons.com/forums/pub...#>/biggrin.png

On a 20B you need to to help cool the engine.

Guys have done slightly over 400 rwhp (470 at flywheel) on stock ported, stock twins, FD engines running about 16-17psi and non-sequential mode.

This is the limit for the stock turbos.

https://www.nopistons.com/forums/pub...1047683894.gif , wow looks like your set for a long long time.

Too bad a T2 engine can't survive 500 flywheel hp.Without internals.Or else I would buy the Series 5 Turbo driveline he has for sale with everything I need to swap into another first gen.

says who? I'm pretty sure it can handle 500hp with stock internals. Its all in the tuning.

Dragon was telling me with the proper tuning and OEM style internals it can hold about 400-450 at the flywheel no more without getting the internals done.

Isn't the to4R like almost 6k and the gt 35/40 only 4k? They can both produce 500 at the flywheel. I also heard you can't rebuild the to4r in the states? And you can get the cartidge or parts for the gt, so all in all i think the gt 35/40 would be a better choice, esp for a street car.

So what else is needed? dowel pinning? Thats kinda like 3mm apex seals from what i have heard, cough* not needed...

Well just have to wait till he gets on, hes got some questions to answer https://www.nopistons.com/forums/pub...#>/biggrin.png

hahahaha.I sure he'll love me for that. https://www.nopistons.com/forums/pub...#>/biggrin.png I can get a newer T04R with new everything for $850 USD.Or a T78 for $900 USD.I'll prolly run a huge snail this fall or next spring.https://www.nopistons.com/forums/pub...#>/biggrin.png

yeah but ya need a manfiold, $500, plus a exteranal WG, $4-500, ya know, buts still that is cheap.

And if your wondering what thread that was.Here yah go. https://www.nopistons.com/forums/pub...#>/biggrin.png

Tell me about it.At least Directfreak knows a guy who builds custom manifolds for just about any application.I want a T04R or T78 hooked up to a HKS 60mm wastegate and HKS BOV. https://www.nopistons.com/forums/pub...#>/biggrin.png that could be fun. https://www.nopistons.com/forums/pub...#>/biggrin.png https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

why a 60 mm wastegate?



luigi

I suppose he wants mad boost control

YEAAAAAAAAAAAAAAAAAAAAH TO4R

Because I can. https://www.nopistons.com/forums/pub...#>/biggrin.png

ok



luigi

the to4r is a normal standard shaft garret style turbo, nothing more, so the overhaul kit from turbonetic's is around $80-90 and you can buy standard p trim exaust wheel / shafts for cheap as well. The only thing special is the a/r 70 compressor housing and blade that is 66.8 mm on the inducer and 84 mm on the major. I'm pulling off my to4r in the the near future because I just picked up a T70 turbo that should be on the car in the next few weeks.. https://www.nopistons.com/forums/pub...#>/biggrin.png it has a a/r .84 compressor, 70 mm inducer and 98 mm major.. any bets on how long the engine lasts.. :yum:

I wish I had some $$$$$$$$$$ so I could take that t04r off your hands. https://www.nopistons.com/forums/pub...#>/biggrin.png



I'd like to see some spool time comparisons between those 2 turbos though.

you just need a good set of 2mm seals a good port and you need to work on cooling the rotors down by putting carb jets in the e-shaft and make sure you have good bearing clearances... lots of power makes lots of heat and that will make hot spots and those cause detonation. Any time you make lots of power regardless you will shorten the life of the engine by a group. On a stock internal engine with stock ports you have lots of back pressure, this limits the hp and it creates a **** load of heat that can't get out of the exaust port this creates very dead engines very fast, ie. sock 13B's arn't going to last long with over 400 hp..

I'm keeping the exaust a p-trim with a a/r 1.0 housing and with my exaust port it should still spool pretty fast, the only thing thats going to slow it down is the heavy ass frisby in the compressor housing trying to pick up speed.. :yum:



lol.. I already sold the to4r to supliment all the crap I need to put on the T70.. I also have a back up to4r that I'm still keeping just in case I kill the new smurbo...

Is that available over here in the US? Whats all in an overhaul kit?

Yep you just need a standard shaft garret overhaul kit, it should come with a rear and front seal, 2 shaft bearings, a thust bearing and thrust coller and the c-clips that hold the bearings in place... you can get them from almost any turbo sales place or from turbonetics..

So if i blew the hotside of a to4r, it would only cost 80-90 to fix? https://www.nopistons.com/forums/pub...IR#>/dunno.gif
