Hi guys,im new here,and also new to the pistonless engine.



After toying with several ideas as to what engine to replace my ageing 8-valve Fiat motor with,i decided on the 13B turbo.Series 5 engines are the only ones we get over here in numbers.



I got a dummy motor from a friend to check the space in the engine bay-and by god,it looks like the old Fiat was designed for this engine.Some minor mounting mods and it will simply slide in.



Im in Johannesburg South Africa.We have a couple of rotary tuners here,some of them running high 8 quarters.But i need to learn about this engine myself,so i dont look like a prick. https://www.nopistons.com/forums/pub...#>/biggrin.png



Im considering a bridge port motor.I do a lot of track work,so i want to stick to the std turbo for now.I need to know if it will still produce any boost at 7000rpm.I know it will get me out the corners quick enough,but will it carry??



Also-i will go for the Microtech ltx 11 i think it was called.



So a std turboed bridgeport motor running at 13psi boost will give me what sort of RWHP???This is with the std injectors,or at these boost levels will i need to go for bigger injectors????



Also,the intercooler lines up with my std bonnet scoop,how effective r these coolers.



Guys,im not interested in 100000000hp,but a useable 220hp or so at the wheels will give me an extraordinarily fast track car.Ohh btw-i want to go to 3mm seals as well.Just for reliability's sake.



What you guys think????

Nice, I presume it's not that damp down there for Fiats of that vintage to still exist https://www.nopistons.com/forums/pub...#>/biggrin.png, keep us updated.

I'm not sure you want to bridgeport a turbo motor. A street port will work well with the turbo. Ive got a street port, with a microtech making 292WHP at 12psi on pump gas. Its in a Miata.

Listen,im green with these things.We have quite a reputable tuner here.I mentioned the bridge to him,and he said he can do it.I dont know the pro and cons of this set-up.



Please tell me.

If 220rwhp is your goal hell you can do that with stock ports. I would go through and freshen up the motor and maybe do a decent streetport on the motor. Don't waste your time with 3mm apex seals if the 2mm slots are within specs. It's a waste of time and money and 2mm seal better and hold better at upper rpm's because they are double sprung unlike 3mm seals that have a single spring. It's all in the tuning there have been many people who have made in excess of 500rwhp with stock 2mm seals with no reliability issues. And I would go with larger injectors if you are going in the 13psi range.

I agree, Street port,factory apex seals are more durable, and 720 secondary injectors.

Hi guys.



Listen,ive bought a motor.Brand new.Was built for short track application,but the guy decided to rather refresh his current engine,which has done 3 full seasons.So durable it should be.It is a 13b gen 5 turbo, streetported,dowelled,balanced and with 3mm seals.Also a slightly modded std turbo.Apparently it runs a bigger compressor wheel and a machined housing.



It was dynoed at something stupid like 450 flywheel ponies.This car weighs in at 820kgs with the old Fiat motor in it,and ive rid it of another 53kgs since then.I reckon 810kgs with the rotor...920 with me in it.That is a positively stupid power/ weight ratio.So if i go quiet......im dead.Send flowers.



Ok i started my conversion on the week-end after i got the gearbox.I slapped the dummy motor on there,cut the tunnel open,and slid the assembly in.



I took some shitty pictures with my phone.

This is the rhs engine mount.I will finish them off and powdercoat them.

I did the lhs tonight.I will do the gearbox mountings tomorrow.

So,am i going in the right direction........?

isnt that fiat a tad small?

You're at the fun part now https://www.nopistons.com/forums/pub...#>/biggrin.png - everything you do seems like huge progress. Soon you'll have all those annoying little jobs and the electrics, just don't let them put you off https://www.nopistons.com/forums/pub...#>/biggrin.png - and a rotary engine in a light car like that is always heading in the right direction.



Mark

Nice.. keep us updated.. its always nice to hear from people in different parts of the world..

Is true hey.If you paint a mounting it feels like youve done a lot https://www.nopistons.com/forums/pub...>/rolleyes.gif As for it being small,not really.Width wise there is plenty space,but the nose is a tad short.The radiator im fitting goes in easily though.Electric fan as well.I might just be able to fit a decent rally spec aircleaner too.



Trust me,there will still be a lot of swearing.At least the set-up of the motor wont be too much of a problem.The microtech has a map in it for this specific engine,so it will just be fine tuning.Thats a big plus for me.Listen,what sort of mileage do you run these things in with?

tranny looks as if it can go back a few inches. that should clear some room for the rad.



and this is what i had in mind when i read "fiat abarth"...

Hell,no.That would have been a tight fit https://www.nopistons.com/forums/pub...IR#>/smile.png This is it,and no it not Jesus,its me driving it.



https://img.photobucket.com/albums/v116/riekus/mas.jpg



Its a helluva good chassis on this car.I was cornering hard there.It actually pissed some fuel from the overflow if you look carefully.This thing corners very flat.I do have a funny feeling it is going to bite my head off soon though. https://www.nopistons.com/forums/pub...IR#>/smile.png

Well guys,things are moving fast.Ive got the radiator in.As well as the propshaft.The diff is back together and im busy with the fuelpumps and swirlpot.The wiring will get done during the week some time and by the end of the week i will take the dummy motor out.Flat and spray the engine bay quickly.Early next month she will be up and running.



The biggest jobs now are indeed the cosmetic stuff,and the clutch master and slave.I need to get the oilcooler pipes made up as well.Im using a Delta Integrale Lancia's oilcooler as it fits perfectly.



Im very happy with the angles on the propshaft.Its perfect.I just hope the diff lasts for a while.



I want to ask you guys some turbo info.I am very scared of large turbos as i am a bit of a throttle response junkie.I need it to be very rapid out of corners.If i want to upgrade to a slightly larger turbo in the near future,what will give me massive power up top,but not be too laggy?A good all rounder.Ive driven one today with a t64 on it.and it has scary power up top,but will be destroyed on a track by a Mini Cooper.



It really only started going at about 4000rpm.Which is too high.I want to be in boost by 2500rpm and at full boost by 3000.



Any ideas????

What do you mean by perfect angles on the propshaft? I'm sure you know but in case, they do need a bit of an angle to keep the UJ's from wrecking themselves.



Mark

Yes i know,between 6 and 13 degrees.Im sitting at 11degrees from gearbox to carrier and dropping another 2 degrees to the diff.Im clearing the top of the tunnel at the yoke by 25mm.So its good.

Ok guys,i downloaded this videoclip of a series 6 chasing down a Lambo Gallardo.

http://64.158.28.140/MPEG/TwinVision/bir_0...ing_lambo_2.mpg



Now,a few questions.What dumpvalve gives that distinct whistle on overrun?It sounds gorgeous.

Also,what turbo gives that distinct high pitch whistle under boost?What causes it to do this.Is it the turbine wheel ratio to the comp wheel or what?



I want mine to sound like this.Its important......... https://www.nopistons.com/forums/pub...1047683894.gif

Havent been on here for a while.Helluva busy.In between i did do a lot of work on the old Fiat.



Ive welded a tunnel in.

So-what you guys think?

Ive also cured the rowing of the gearshift once in gear by fitting a very small little spring to the guide pin under the bush where it locates on the ball.Feels like a new box now.

You don't hang about!

https://www.nopistons.com/forums/pub...#>/biggrin.png I have an itch.My first rotary conversion.Need to find out what all the hype is about.

Thats looking good. Nice job.

Wow, that is a really clean install. I like it alot. Good job man!!

the dumpvalve in that video..

i believe it's an HKS Super Sequential Blow-off Valve (HKS SSQV)

not sure about your other question though...maybe....external wastegate setup?

Well-guys-its playtime.I had some issues with the time the engine builder took-so him being a guy that still has the passion and the pride in his work-he gave me a Turbosmart wastegate,tubular manifold and a hybrid turbo of some sort.



Pretty cool hey.So i got the motor on the day before Christmas-and we were making noise on christmas day.Not bad.



Nothing is tuned yet,so i just started it-drove it around the block-did a donut-and parked it again.I have to wait for the people to come back to work now.



You guys should see the ports on this thing.......He also fitted some fancy lightweight rotors.This thing is going to be wild.The turbo set-up i got on there now did 400 rwhp at 1bar boost on a motor thats not as wildly ported as mine.It has that distinct bridgeport idle.Who knows.......



Anyway-here is some more pics.I had to redo the oilcoolers yesterday and fit a larger radiator.Thats all done.

by the way is a cool setup and the car looks good

I havent been here for a while.Well,it wasnt all plain sailing.Some engine problems,redesigning the whole car and some minor niggles.It has done 1000km so far.No problems.Im running it mildly,.8bar boost and no more than 8500rpm.



Produced 330rwhp at this boost and weighed in at 766kgs.did a preliminary 11.7 at 201kmh run.I have serious traction issues though.



I hope to be in the tens by year end though.

Wow, that is a neat looking car. Great work.

Thats sweet.They'll never suspect the fiat. https://www.nopistons.com/forums/pub...1047683785.gif

holy monkey .. thats crazy..
