Capri Mk1 OHC Pinto Turbo GT28R

Hello!
First I have to say: Skogenracing is great, awesome projects!
I have seen your videos on youtube. Awesome powerful cars, really!

Now, my actual project is a ford capri mk1 with 2.0 OHC (205 Block) and 8,5:1 compression.
I use it as a daily driver in summer and as a drift car.
I will install a Garret GT2560 (ak GT28r) Turbocharger.
What do you think about this turbocharger? I think it will be great because it spools very quick and is good for
200hp+

Before I begun with the turbo conversion, the car makes 120Hp and 205Nm on the dyno !

modifications:
- my selfmade race exhaust with 63,5mm (2,5")
- 38/38 EEIT Carb
- Intake Manifold adjusted
- electric fan
- standard 105Hp Sierra Injection Camshaft

Here are some Videos BEFORE the Turbo conversion:

My wish is to get 180-200Hp with low boost. I think with max. 0,7Bar Pressure.
than the second question, what should I use?
Sierra EFI Injection or Carb ?

I have lots of Information about Turbo-Carb convertion.
I would use this:
http://www.burtonpower.com/malpassi-fuel-regulator-turbo-with-single-carb-fsefpr009.html

For Fuel Pressure Regulation. and the 38/38 EEIT Carb from the original 188HP Capri Turbo mk3.
I use a FMIC from Audi A4 1.8T.

My Local Friend and Tuner said to me, I should use a Mulitpoint injection, Carb don't work well, he said.
I have some standard 2.0l EFi engines in my garage, but never used them!
But I don't know anything about the EFI injection. Dont know what injectors I should use or how I can remap this thing.
Do you have some Informations for me about the EFI and how I can remap this thing to get a good result?

I hope you can help me ;-)

greetings from germany,
Erik

I have still some questions:
Where do I get a Turbo Exhaust Manifold from ???
and how well does a Volvo Manifold fit? this one:
http://www.ebay.de/itm/Burstflow-Turbokrummer-Edelstahl-passend-fur-VOLVO-240-4-Zyl-T3-T4-T70-K27-/230866267420?pt=DE_Autoteile&hash=item35c0b3ad1c

I hope someone can answer my questions.

Here is the intercooler from my old Passat 1.8T now in the Capri:


(Intercooler should be good for 220Hp and max. 1 Bar, but thats enough for me)

And here is the Turbo, still with the qustion: Use it with small turbine housing or with big turbine housing ?
my tuner said, I shall use the big turbine housing.
But he also said that with the smaller one he use the Turbo on Vw/Audi 1.8T engines with around 320Hp,
and I am no fan of peak power. I like good overall performance.



greetings, Erik

Nice projekt! I don´t like carburettors, especially with turbo. Hard to get it to work well. I would suggest a aftermarket EFI system

The T28 will do fine, use the large turbine housing to let the engine breath better.
I suggest you make you own exhaust manifold, it´s not hard if you can weld

okay! I try out the large turbine housing!

I already have a EFI System in my Garage. I read that it would be good to use
Standard Injectors and K-Jet Injectors (from 2.8i Capri?)

how can I get this thing running? and what else do I need to make a good EFI Turbo?

A friend of me runs his Turbo engine with the 38/38 EEIT Carb (the same as I have). And it works very well,
producing around 300Hp.
making around 270km/h topspeed without any problem.
https://www.youtube.com/watch?v=mo_JVJxqgmU

What brand of EFI is that? I you use this as some kind of daily driver i would not rekomend K-jet injectors as extra fuel

If you have a friend with this carb setup that works well why don´t you just copy it then?

yes, that's the fact, I just want to try the same setup that he drives with carb.
maybe it will work.

It is the original EFI from the Sierra 2.0. dont know whats the difference between the EFI Injections.

The stock EFI wont do, you need a aftermarket one that is adjusteble

God damn, never heard of something like this. I hate germany, Informations are like Gold here.
where can I get a adjusteble Efi?

and is it really so good to use bigger turbine housing?
The Small one is called "A/R 49" and the big one is a "A/R 64"

If I can't find a working injection, I better use my carb + broadband lambda sensor...

I have some more questions. This is the Diagram of my Turbo (GT28R) with Big AR64 housing:


But i have only a small AR42 Inlet Housing.

Is this still good enough or should I better use a bigger Inlet Housing?

Hallo man , lass die scheiss Vergaser einfach weg ... also jetzt auf englisch , damit die andere auch verstehen können... und zwar ... axaust it's not a problem , i can help you with cuting , welding and etc... , i sent you 2 pm s ... and i think we have to meet . Obout the pinto ... it^s just a simple engine .... reliable and may be the best budget solution , you just need cosworth pistons , con rods and crackshaft after that , so it's cheap ... or let's say a lot cheaper than VW or Audi tuning ... the only problem you have , has a big sluty name called TÜV, and exctly TÜV is the reason , why i'm not driving capri in germany... so i bought a mint 200 sx s 13 with 230 BHP ... so what do you think about next drift day in ULM ?

Here are some news. I am building a new engine.

want to use double piston cooling. the original pinto rod cooling and the cooling system from cosworth 2wd.
do that work? or could there be some pressure problems?

I thought that would be great becuase both sides of the pistons will be cooled down.


here are new pictures:

200SX S13 1.8T turbo manifold CA18DET Engine or something like that.
fittet on a pinto flange, need to made it a bit longer.

I found out, that the LANCER EVO 4G63 turbo manifold is nearly SIMILAR to the pinto ones! fits easy with flange swap.



nearly done! just need to install the fuel pump. it is from E55 AMG Mercedes with 4Bar Pressure and 200litres/h


I use a special built fuelpressure regulator for turbo with blow trough setup.
It is the newest malpassi fuelpressure regulator and not even on the market yet.
You can adjust the pressure very exactly to the boost!

polished and portet head (inlet not polished ;-) only outlet:


And new tires for better grip:



Regards, Erik

I also use a 6 litre FMIC.

Looks good! You don´t need more oilcooling, skip that

Car is now finished  

A friend of me can weld very good and so we cut off a Nissan S13 Topmount Turbo Manifold (CA18DET)
make it 9-10cm longer and weld it to the pinto flange.



Then We need to weld a T25 flange onto it, originally it was a T3/4 flange.



Than we weld the downpipe:





And now, here is the turbo:



We tried this turbocharger on a Vw Golf Mk2 1.8T and produced 370hp at 29psi! Running a 11,9sec. on 1/4 Mile !

Works very nice. We modified the turbocharger a little bit. Bigger Exhaust Housing and "polished" exhaust housing.



Using Innovate MTX-L to set up the car. Still working that the engine is running good.

I have a problem, that the car runs great if it is cold, and have issues between 2500-3000rpm when its hot.

under 2500 and over 3000rpm the car runs great.

regards, Erik

I could suggest you cheap and good fuel pump!
Bosch Fuel Pump 0580254910 High pressure pump with fairly good fuel output.
If you use 4 bar fuel pressure 2x these pumps are better than one 044 pump.
(there is cheap model from this Bosch costs about 50€)

Is your ignition ok at 2500-3000 rpms? Could it be that it won't burn properly all that fuel?

With that comp rate of 8.5 you should be able to use about 1.2-1.4 bar boost with 98E5 fuel.
E85 makes possible to use about 1.5-1,7 bar boost without detonation. Though I don't know if there is available that kind of fuel...

2.8i Capri injectors won't be able to you give you more fuel than about 230bhb... or you might face detonation.... I had Micro Dynamics extra fuel injectors  same as  Tickford Turbo Capri and they were enough to produce about 300-350bhb (2.8 cologne) then I run out of fuel even with high fuel pressure 5bar.

Higher then boost you use, the better engine "breaths" even with bad cylinder heads. There is not much difference whether it is 12v or 24v if you have 2-3bar boost. 24v get same power with little bit lower boost at low boosts then 12v but at  high boost there is really not that much difference.

I hope everybody understood what I wrote  and meant...

Thank you very much.

The problem was that my "cold-start-jokes" on top of the carb was damaged.
so that not all the air could get into the engine.

Now this problem is solved but the engine runs now too lean.
Lambda 1,2 (AFR over 16) is much too lean and I will damage the pistons if I dont change it.

Maybe my fuel-pressure regulator dont work well. I will change it today and if that dont work
I will install bigger main jets and try it again.

My boost is around 0.5 Bar at the moment and the car accelerates very good
beacuse my engine runs great even before the turbo conversion. I also installed some leightweight parts and the
car has only 900 kilograms . I had 204Nm tourqe at 3000rpm without turbo and a wide powerband with 120hp from 4000 to 5700rpm

I will dyno the car soon with the turbo and see what happend

hope that I get my fuelmixture to a good lambda 0,75 to 0,8

I am running my Turbo Mk1 Capri at max load 11,4 AFR and small load 14.7 AFR.
If you don't care about fuel consumption you should Aim for 11,9 and 14,5 AFR ratios.

So far 3.500km and no problems. (There is some problems but they don't effect driving so far)
Max boost ~~1,4 bar

Quote:"Bosch state that most spark ignition engines develop their maximum power at air/fuel ratios of 12.5:1 - 14:1, maximum fuel economy at 16.2:1 - 17.6:1, and good load transitions from about 11:1 - 12.5:1. However, in practical applications, engine air/fuel ratios at maximum power are often richer than the quoted 12.5:1, especially in forced induction engines where the excess fuel is used to cool combustion and so prevent detonation."

Only New engines can handle AFR higher than 15, and normally they have high compression ratios and special sparkplugs, like new Mazda 2.0 Skyactive (compressionratio around 14)

With turbo car sparkplugs makes huge difference... so you should also choose right ones.
(Not more power, but prevents detonation)

Now the car is running great. Had to do some work on the carb jets.
Changed Power Valve Jets from 70 to 150 and Main Jets from 150 to 170.
Than the Full-Throttle-Jets from 50 to 70.

Now running AFR 11,7 at max load and AFR 12,5 to AFR 13 at small load.

runs good even with low boost:

here - the car was on the rolling road :-)

watch the results at the end:

188Hp and 229Nm tourqe.

Done some test driving this year. car performs well on the roads:

Very good! It sounds great!
Where did you get the wastegate?
Nice car!
