Turbo

[Guest subk]

i have been interested now for a while in getting a turbo on my pinto the only problem is i have not seen many turbo kits for them. i think i may try the cheap option and try and build one. has any one sucessfully done this yet because i am haveing trouble finding out:

 

(a) adapting the original manafold (can this be done)

 

( where do the oil pipes come and go out the engine

 

© which turbo would be most suitable

 

if anyone has any more information that may be of use the please let me know

there are a couple of nut-cases out there with blowers fitted (or in the process of fitting them) the easiest way to find out more, is to use the search button at the top right-hand side.

Hi,

I hae been thinking about the same thing, but alas I sold my modified engine before the turbo idea took-off.

 

I think it can be done relativley cheaply, get a small turbo fromaa scrap yard TurboDeisel ect. most often used for 1.9 TD engines is the Garrett T2 these can flow upto around 200-250 hp worth of air for a petrol engine.

 

The oil pressure feed, is easiest to get a sandwich plate for the filter, or workout where abouts the oil channels are in the block/head and 'tap' into one of them(drill and thread it) . - would look pretty neat..

 

The manifold can be tricky, i was going to fabricate my own, but have since lost interest.. I have been told since that the Ford Transit Turbo Diesel manifold is the same stud/ port patern, and so can bolt striaght to the pinto head. Not sure if this is 100% correct, worth looking into though.

 

Need to make a plenum chamber to pressurise your carbs/ or else just straight into the Inj manifold.! with an Inj engine, for starters get an adjustable fuel pressure regulator - easy way to increase the fuel delivery to meet the increase in air mass.

 

good luck.

 

Im thinking of building a Ford Zetec V6, when the bling comes along. wonder if Turbo manifolds can be bought....hmmmm

Ahh just started to do pinto turbo stuff.

Manifold first it all depends on how much room there is on my 2b there ain't much.

the manifold i'm doing at the moment is to fit the mk1 & 2 escort, Its to go on my

RS2000. But i do intend to get round to doing one for my 2b but of a different shape to fit the engine bay. Heres some pics of my current one.Its not finished due to my new T2 turbo not turning up yet but it should give you some idea.

Also you will need to reduce the commpressoin from (i think) 9.8:1 down to 8.2:1 or for big boost ( over 15psi) you will need to go to 7.5:1.

My cheap option is a head spacer plate. But if using standard pistions 160 to 180 bhp max. if forged pistons are used then 350bhp is about the limit.

The compression ratio is the bit that seems dodgy to me. Not sure how well a spacer plate would work - hopefully very well. Anyone know what sort of compression ratio would result if you stick a 2.0 head on a 1.6 engine? You should still be able to get in excess of 200bhp (brown trousers time) from a blown 1.6.

You can't use a garrett t2 diesel turbo on a petrol engine. The petrol t2 units have a turbine wheel made of inconel which will take the temperature. the diesel turbo has a much cheaper turbine wheel. You can tell an inconel turbine as the end is triangular. The diesel turbines have a hexagonel end.

Go for renault a 5 turbo (bit small) or a Nissan Silvia unit(better) a T25 unit from a late escort would be better.

If you use a diesel turbo, It will disintergate very rapidly

You will need an intercooler as well, and you will have have to remap the injection system, and remap the igntion for boost.

All in, a lot of work. It took us a Turbo Technics, a long time to make a good trubo system for a pinto.

Your best bet is to use an existing turbo engine complete, or keep an eye out for an old turbo conversion from T.T or Janspeed etc.

If you make up a new manifold, built it as beefy as you can, preferably in stainless, or use cast bends, and strengthen it with webs. It will crack eventually anyway.

t2 , t25 wot does this mean, only asking as my engine(rs turbo)has a t35 hybrid ?

[Guest Robin Allison]

This is the turbo i have. it has a hex nut on the shaft. But also seen a T28 off a 200sx that had a hex nut also?

[Guest Robin Allison]

This is the T28

The Japanese did sometimes use some non-inconel turbine wheels on petrol engines, but they didn't last as well. We used to rebuild more Nissan turbos than any other make. As far as I know, all Garrett inconel wheels are trilobed, but you may want to check with a Garret agent.

A diesel engine exhaust runs at about 800c max, a petrol engine can go over a 1000c

At this temp, the turbine is glowing orange. we used to have turbos on engine dynos where you could see through the turbine housing they were so hot. At this temp the turbine wheels can creep outwards until they hit the housing wall.

The Garrett web site has quite a bit of info.

[Guest Robin Allison]

Charles any idea then from the pics what i've got??

[Guest Charles B]

It's a T25 unit, If you can tell me the number on the metal plate pinned to the centre housing, I can tell you.
