Morning gents , am not realy sure where to put this so am sure mods will let me no.

Anyway, you guys have a lot more turbo no how than i do, now ive been told the T3 is old hat and to get a more modern turbo.
My engine is basicly a metro turbo motor but spec is as follows

1293cc
Forged omega pistons
lightened/ ballenced crank and rods
36.0 and 30.0 valves are 21NS stainless steel and plasma nitrided with waisted stems on both inlet and exhaust and 3 angle valve seats, new silicon bronze hi-flow valve guides.
1.5 roller rockers
Kent 266 cam
11 stud head as aposed to 9.
running 7.5:1 compression
utralight steel flywheel
ap padel clutch
Jackknight straight cut gear box and atb diff.

Now some of you may understand that but am sure will be baffled.

Most of the miniturbo lads are running a gt17 from a saab
but im looking into a gt2056 that iveco and renault vans use .

Am just wandering if any of you guys could help and advise on somthing that is easly available or better, i beleve on my com ratio a could runn 25-30psi

Can ANY one help me the lads on the turbominis site are brilliant but ive owned loads of fords aswell so would realy value your comments.

Thanks Rick

 

Chip off here is your man mate

 

jeezo that is one serious A series mate. What power figures are you aiming for? and what usable engine rev range are you wishing to have?

 

Mini a series that brings back memories, I had a souped mini had a ex stud nicklaus sprint engine, stroked crank and relieved block for 1558cc I think it was, went like stink that was t3 on a cut down 45.
Anyway T3's could be described as old hat, wing to the vastly better from a lag point of view GT series with roller bearings.
I'd be cautious about using a turbo from a tdi, but if it would take the temp why go the whole hog and use a variable vane turbo as fitted to some tdi.
Why not efi it and use management be even better then ?

I know a lot of the R5 boys use the vag VNT turbos, as they have variable AR exhaust housings, to reduce low down lag but still keep the engine free breathing high up.

 

have forwarded these questions to a colleague who has built several mini turbos in the past

will post up his responses shortly

also if you can get hold of tom fenton on turbominis, he knows his stuff (tell em rory says hi, i was at uni with him)

 

We i do have a better spec race head for it and with the old t3 i was only running a bar of boost and would easly do 7k and aseamed to want to go more.

They do a specific turbo cam aswell but this wasnt available at the time when i had the engine built many years ago, it was only run for 18 months or so then escort cosworths and the likes get in the way .lol
Been re building it the last few years now into a track car rather than road.

So come on chip then it sound like your my man!!!!

Thanks Rick

ps, carnt use managment at the mo with the siamese ports? on the standard 5 port head

 

Hi, yes i no tom myself him and carl austin (forceracing ) have built a twincam 16v head on the mini and last 1/4 mile run was 11.1 i beleve. Very impressive front wheel drive.

rick

 

Cant you use a mono-point injection system? the best power and drivability will be had from programmable efi

 

You can put EFI on Siamese ports but you'd need massive flow rate injectors (Standard MPI's run 470cc I believe) or Single Point Injection (as said above).

Serious engine though. Whats the max that the JackKnight boxes can take? PM AlexF about turbo choice, he does alot of turbo mini's.

 

Its still running the su carb, its the only way realy, but ive got rid of the dizzy and gone for the mega jolt mapable ignition.

Rick

 

Well all depends how there used i supose but theres a few funning the 200 mark , but the first thing usually is the transfer gears.

Dont realy want to get too involved with the injection to be honest, if anything does happen it will be a long time off but there doing a 7 port alloy crosflow style head that i could still use this turbo/manifold combo but with a plenum up front on a single throttle body. dont want to get into that yet theres so much more development to do with the car as its a one off spaceframe ive been building but ive had the said engine in a standard mini allready.

Oh and ive got a dog box if the syncro straight cut gives up.lol

Rick

 

Get some pics up of the old girl ricardo

 

Dry build first


Then strip n paint frame



Then build up



Then shell back on


And as it stands now





There you go max
Rick

 

No half measures there!

 

That looks awesome! Borg K04 turbo would be really nice, about 250hp capacity and probably be fully on song at 3000rpm.

Rick

 

Oh, and with all the effort you have i'd ditch the carb. So much to be gained with something efi. It's much more reliable once running. If you were near Manchester i could help you with all the management etc.

Rick

 

Rick is the ko4 same a like seat leons etc, maybe next winter for the efi bit , i just want to get the dam thing sorted it been too long, ive had a few opp's latley and were crazy busy at work aswel so it allways comes last. Plus theres going to be loads of development with suspension an brakes, runnig separate remote master cylinders a 6pot calipers up front.lol

rick

ps im just other side of you , huddersfield/wakefield area

 

That cage is tremendous!

 

That's come on since I last seen it rick. Smart as!

 

Thanks, andy.

Come on guys anyone got an idea for a turbo for me !!!!!!!!!!!!!!!!

Rick

 

What about a ko3s smaller than the ko4 but will still flow 220-230bhp

 

Rick,

the K04 is used on the Seat cupra, Audi TT and Audi S3. K03 is used on the low power VAG 1.8's, which develop 150-180 as std. There are loads of these around so you could experment with a KO3 then goto a KO4 if you want more.

Wakefield isn't far, so get in touch if you need any help with the megajolt side of things, fully mappable ignition is already going to be a huge bonus.

Rick

 

So do you think the gt2056 couldnt cope with the high boost temps with it being off a deisel, the gt 17 the other lads use is just for road cars and drag strip runs, so thats why i think they havent had probs.

Thanks for the offer on the ignition rick, i may take you up on that bit it will be in the new year.

rick

 

i'm building a mini turbi just now,
pretty standard not in the same league as yours(very nice btw),
i'm just wondering if an old su could possibly cope with 25-30psi stuck up its arse?

 

Yep built properly theres matt woods hes a photographer for the mags , yes he runs gas aswell but has made over 300hp with it. but rebuilds and checks it every winter.

The su on na wont do the power but as its forced induction its fine.

Rick

 

Sorry gents to keep pestering, a friend had some flanges cut so i got him to do me some for the gt2056 so that would be the ideal turbo to stick with, just wandering if you turbo buff's think it will do what it should.

thanks rick.

ps Oh ive had a phone call and i may be back in cosworth ownership soon, keeping it quiet at mo incase it doesnt come off.

 

F*%k me i thought the back end on mine was light weight. Cracking Project keep up the good work

 

Well the shell with frame and steel doors was 430kg

I now have alloy doors ,plastic windows but its all the wireing water and fuel lines etc that will add up. Id be happy at 550kg

rick

 

Id swap it for a nice series 2!!! Never seen the mini rick, looks immense.

 

Funny enough was talking to my friend Matt yesterday about the same thing, he's thinking of a change on his Mini turbo (best figure to date with his A series 310bhp iirc) think on a T3, haven't got the rest of the spec to hand

You could sign up on turbominis.co.uk for advice?

 

It will hopfully be out next year steve !! wel i said that this year but with hurnia opps and now back opps am struggling.lol

Is that a certain matt woods, yes i no who you mean ,he runs gas aswell to get those figures, im on turbominis quite alot they all seam to be using gt17 from a saab, i was just wandering from some of you turbo boffins on here wot they sugested. think im going to try the gt2056.

Rick

 

Why not put another engine in it? you have gone to all the work of making that lovely space frame and getting the shell all minted up, Will a 16v from a metro not fit? or a big bike engine?

 

lol I've known him for 10 years and never knew that what do they say about women never listening granted it's also been about 8 years since I've been in it (although common sense says it must have a shot)

Had a feeling you weren't completely new to minis by the pics above

 

Im going to completely contridict myself right now.

Im a mini person, had one before i could drive etc, and beleve a mini should have a mini engine in it.lol (could be stupid jut my thaughts)

But then again ive cut it all up and made it into a spaceframe, so there is just the outer (steel though ) shell.

Theory being minis rot for fun , so this one shouldnt and it will be allways somthing i will keep and its a one off.

Saying that ive had two escort cosworths and loved every second i owned them, cousin had a series one, and i used to use that more than him when i was 18 lol .

Am just on with trying to get another rs at the mo as there a passion of mine aswell.


Rick

 

I understand the ethos with keeping the A series mate, otherwise none of the original car would excist lol! just thought somthing a bit more modern, would suit your modern space framed approach. A hyabusa turbo or something of that flavour, light, powerfull and reliable, if a little missing on the reverse front! keep up the spotless work though, very good soo far.

 

thats cos Daz didnt know how to use it, just ask him about the time my standard s2 beat him up parkside

 

Exactly, should of shown him how to drive the 3door aswell.lol

You coming to donnington dec 29th, il take you out in the evo!!

Rick

 

such a shame that 3dr, never got used in anger even at the ring sounds like a plan for 29th, see if all the boys can come down, be a good crack, bring my point and shoot also

 

Awsome, well once it gets warm it puts flames as high as the spoiler.lol, i can only see it when its dark but wen the lads have been following says its ace i just need a pic of it.

Anyhow, still no one got anymore turbo advice for me or wheres best it speek to.

Am wakie west yorks

Rick
