about 3months ago i bought a super s engine and wanted to turbo it but never had the time but today the project started me and my friend at work have gutted the engine replacing most parts were trying to go for biggish bhp but strugglin to get forged piston
ill post some pics up soon thanks for reading |

I've always wondered, considering that the cg has same bore and stroke as old school mini, if these can be used? otherwise its custom, I think. Good luck with the project.....

im in sheffield ive found some pistons but ive also now been offered a system that will alow you to run 18psi of boost and alters compression im not definite how it works but im going to look into it

cheers mate just having a problem now getting hold off a full gasket kit and big end bearings and piston rings one of my mates who works at a motor factors is looking into it for me
purchased my turbo today its a t2 off a renault 5 gt turbo only done 3k miles and no play car was scraped because of bodywork makes me so happy |

well done on the turbo ! motor factor stuff is pretty thin on the ground for k11 engines i have found, one reason i think is that the rings and shells etc are sized and graded/selected which keeps the tollerences on these CG,s extreemly accurate ( thats why they,ll take so much stick imo ) |

i still cant believe the build quality internally its unbelivible so simple but so reliable ive been in touch with my mate at the motor factor he mays have sorced me some bits so im very happy
manifolds been modified today awaiting turbo now |

right turbos arrived using all orginal parts manifold has been chopped at bottom and going to weld a flange straight to it seen it done on this site turbo is been reconditioned by myself its all in a days work ha ha
the head i dont really want to skim it but its abit rough but for my own satisfaction im going to do it so now theres the worry of compression im wanting to run 7psi for trackdays and normal daily driving it will be 2-3psi and adjustable for different styles so any help guys would be a massive help all gaskets,piston rings and bearings have all been sourced £160 all in im ver happy with that |

what pistons are you planning on using? 7psi is a fair bit of boost to be using on the track on stock pistons even with lower compression... constantly on the go pedal. how do you plan to run 2-3psi? why did you reco the turbo? you should be getting your oil feel of the oil pressure sensor, the head is the last place to see any oil, just gaurantees oil is going to get there quicker.

standard pistons but i work with a lad at work and he builds track day cars so hes helping me with boost and stuff adjustable boost controller most likely i recond the turbo for my satisfaction i was going to get the turbo feed from there orginally but was assured it would be ok from the head because there will be a constant feed due to pressure and oil going to the cams
it will be seeing the track once in a blue moon if it goes pop ive always a spare engine that was my idea so i could keep messing around till i got the perfect combination on standard stuff really |

as i recall blue monster ran its oil feed direct of the head and as far as i know there was no problems

yeh no problems. just a better way to do it. early 4g63's used the oil feed from the head also, it is well known for them to starve oil from the turbo because,.. it is the last place to see oil. blue monster never saw a track... you can hardly say its a fast reliable car if it doesn't get used to its full potential, but then, it wasn't built for the track either was it. was just wondering how/what actuator you were going to use to run 2 psi. i've been hunting for a while, and the lowest boost i can find over here is about 5psi.

As Turbo march said......not a good idea to get turbo oil feed from head, especially if car is going to see the track. Best location is to "T" off where the oil pressure sender is on the side of the block with the oil return goinmg back to the sump directly.

it wont be always a track car once a year general use really.acutor im not sure bout that one mate weve designed something that has been tried and tested by the guy at work so were going to try it on mine sorry if i snapped i had one of those days sorry to u all
ill get a pic of what ive made to t off from the head if i can find it losing everything ha ha |

heres a pic of the head after 4 hours of cleaning and 6 cans of carb cleaner all oil ways are clear now and intake and exhaust side have been cleaned
manifold has cut down more to fit the turbo flange lambda hole has been plugged ive been told i could have the car remapped so it wont need lambdas can any explain how thanks james sargent |

james
most of the time the ecu is running on closed loop, where the lamda analyses the exhaust and the ecu sets the mixture to suit i think your man will remap the ecu to run without the lamda feedback ( expect a low mpg! ) |

i had a chat with some one yesterday you can get an acutour (sorry about spelling) that can run right down to 0psi so the turbo isnt working at all bloke at work owns one ill get a pic tuesday when i get bak to work
cheers frank2 your imformation is always a help to me THANKYOU |

right boost problem has been thought about and it is very possibe im goin to use the same setup a toyota starlet uses or possibly ford rs turbo a simple swith to change boost and able to run the boost i want u can run any boost you can also make the boost that low you can turn the turbo off loads of new pics to be posted when i get in from work thanks for reading james sargent

yeah, i was gona use the starlet one aswell, the ones we have over here(import jap cars) still run 5-6psi on the stock actuator. being able to run 0psi would be awesome!

its jap in uk but there adjustable to your engine management as far as i know
all u nned is softer springs in your acuator and u can run as much as u like or ther is the option of leaking boost adjust dumpvalve internals etc etc |

sarge3uk WROTE: "its jap in uk but there adjustable to your engine management as far as i know all u nned is softer springs in your acuator and u can run as much as u like or ther is the option of leaking boost adjust dumpvalve internals etc etc" hmm, yes i realise putting a softer spring in it will let you run less boost, but didn't want to go hacking up an actuator and have it looking pov and dodgy. leaking boost out the dumpvalve or bov isn't the greatest idea, makes your turbo work harder then it needs to..shorter life, etc, although this would be more of a problem at higher boost rather then at 2 or 3 psi.... manifold looks. er, custom designed what pistons / headgasket did you end up deciding on? |

pistons goin in normal.im going for a genuine nissan one ive been reassured it will have a much longer life span compared to others
manifold is going to be heat rapped so it dosent need to be perfection really and like stated before im goint to be using the standard manifold because it has been done before with no problems |

and u get a proffesional to do the acuator im not going to be running high boost so i havent got to worry because it will be used mostly for 2-3psi unless i want a quick blast with 7psi

if you have a look at my car on this site, you'll see that its pretty professional, there's no real way to cut and actuator in half and put it back together again and make it look good, but i guess if you hide it well enough it'd be ok. genuine pistons? what headgasket are you using then? and what thickness?

pretty professional ???? your workmanship is awesome imo ! lads, why would you want to run at 2 or 3psi ? if atmosheric pressure is 15psi another 2 or 3 will hardly make any difference surely ? it seems a lot of hassle for about a 5hp gain ! |

cheers frank2 always make my day.just made my turbo flange today just little more grinding then ill get a pic up and get it welded on
i could run 5psi and still be running strong the turbo is a t2 off a renault 5gt turbo my fone is crap for pics so it makes everything look worse but thankyou for commenting on my workmanship made me very happy pretty proffesional and that matters because mine will be just as reliable |

when I had first installed my turbo with standard injectors and no intercooler.... (dont recommend, by the way) had approx increase in performance of 20%.... that was about 3psi....
