Single turbo conversion kit.

[Mark 4]

Manifolds, gaskets, water hoses, oil hoses, mating turbo flange of your choice, downpipe and gaskets. Gonna cost around £1200 to £1500.

Anyone interested ?

[Nutter_John]

Thats a good price there Mark , I assume thats with 3" downpipes mating up with the stock exhaust

[Mark 4]

Can be whatever size people want John.

[aboo]

What turbo will this kit marry up to Mark?

[Mark 4]

Any turbo you want Andy. Would need to be sent to me for the pipes to be custom made though.

[foxdie]

Mark, you able to recommend a particular tub to go with this package?

[Nutter_John]

What power you after Jason ?

Ball Bearing or Journel ?

[Gowf]

All down to ££££££££ jason, that and what power you expect, how happy you are with lag etc.....

[Wobble]

not including the tub and kit what else will be required

[foxdie]

I would say ideally 400HP with as little lag as possible, whichever bearing type is more reliable (ours are journal aren't they?)?

:whistle:

[Gowf]

you want a garret ball bearing then.... something like a GT30 should do you for that. If you look at Richard (Zentac)'s posts over the years, i think he started with a GT30 so you'l get an idea of lag and potential power from that.

[Mark 4]

Mark, you able to recommend a particular tub to go with this package?

No, that is down to personal preference. I actually have no experience of this - other than fabrication - and a williigness to learn.

[Mark 4]

not including the tub and kit what else will be required

Control, - either piggy back or standalone or flashed., Wastegate, inlet setup ( can be arranged) not really sure what else.

[Nutter_John]

That will give you a nice 400 bhp @ 26 psi but will still be in range at 460 bhp

[Gowf]

As Mark has said there will be other things needed for 400bhp.

The wastegate you wont need as you'd get a turbo with an internal wastegate (makes your life a lot easier Mark, as im sure you'd charge more for including the external wastegate pipework. You also wont be able to use a flashed ecu alone as you will not have a maf so, taking what ive said from the other thread:

new inlet pipework to the turbo and air filter
I'd recommend a bigger intercooler
injectors
fuel pump
FPR
ECU (piggy back or standalone will do the job depending on budget)

All in all though getting all what Mark is offering for that price is very very good!

IF you go for the bigger GT30's you will need an external wastegate, which are around a further £350 + flanges and the extra pipework for the manifolds.

[Nutter_John]

Gareth Check the ebay add as they have the option of adding an internal wastegate as part of the selection process

[swinks]

Well, Mark... if I understand correctly you will undertake any custom job in fabrication either intake or exhaust side for tubbys?

[Mark 4]

Well, Mark... if I understand correctly you will undertake any custom job in fabrication either intake or exhaust side for tubbys?

Yes Tomasz. Tell us what you want. If we can do it then we will give you an estimate. If we can't then we will tell you.

[swinks]

Not decided yet, still thinking about KKR 280 as future job. Those are Garrett style turbos. So possible job will be making manifold flange adapters (Garretts sqare 4 bolts to Mitsi triangular 3 bolts) and to fabricate exhaust side pipe from turbos to downpipe.

Yep was just looking at that on ebay when you mentioned it, quite freaky :)

injectors
fuel pump
FPR
ECU (piggy back or standalone will do the job depending on budget)
Not sure about the inlet pipework but I've got a HKS Hybrid Panel filter.
I have a medium aluminium intercooler nigh on identical to the kits you sell / were selling
Just picked up some SARD 530CC injectors from Mark 4 :)
Got a walbro 255lph fuel pump and a fuel pressure regulator ready to fit
Planning on tying all this together with a ViPEC

:thumbsup:

[Nutter_John]

You will not be able to use the stock inlet pipes or air box as the tubby will have to sit where the maf sits now

[foxdie]

Battery to boot and maybe an APEXi Power Intake then?

Guessing under these conditions the stock air box (and as such panel filters) cannot be kept.

[Nutter_John]

no space really as the 3071 is huge so the only real space for one would be to site above the gearbox , this would keep the exhaust pipes from both banks equal lenght

[Gowf]

True, but they dont need to be equal length, in an ideal world yes, but you can do some good things with the diameters of the pipe and the radius of bends to compensate for things like that. Above gearbox is the only really sensible place for it though.

With the induction pipework, you again dont have to use the stock route. It'd be far nicer to swap the throttle body to the other side of the plenum like a few people have done.

All in all though Jason your well on your way there bud!

[enigma]

May I suggest an example kit is shown?? Having done a single conversion myself the price seems fair, but it could potentially be done quite a bit cheaper. If you look at the conversion I did on Richs FTO we reused the stock manifolds, with one turned through 180 degrees and then it was a very simple pipework job with just 4 small flanges required.

[Mark 4]

Once something is made then the pictures will be put up Dave. At the moment all I have is some flanges and bits of pipe.

This thread is just to get an idea of how many people may be interested and if it is worth making jigs so that we can make things for people.

Nothing can be done until the barn/workshop is finished and that's a few weeks away yet.

[Colin Wiltshire]

Just out of interest. I have a pair of kkr280 tubs. With the fitment issues with fans a/c and power steering, was wondering if it's possible to make something to move the tubs to where they wouldn't interfere, eg the front tub over nearer the gearbox. Please correct me if this is impossible, but it's just an idea I have

[bradc]

Yeah it is perfectly possible to move them just about anywhere.

[enigma]

Some pics......

I estimate that the pipework cost less than £100 including the flexis and the flanges were around £50, probably another £50-100 on additional bits and bobs and job done. I guess you have to look at intercooler pipework as well and I think Rich splashed out ~£200 on pipe and silicone. OK it is not the prettiest but it worked! Once covered in the obligatory heat wrap you would never know.

[Mark 4]

Hmm that's an interesting idea Dave. But surely you replaced the front manifold with a spare rear one as the front one would not align to the studs if you turned it upside down ?

[enigma]

I cant remember........I think that we thought that as well, but in the end I thought we had got over that issue.......

[Mark 4]

Well I've got a spare set of manifolds so when the time comes I'll check it out. Thanks for sharing.

Equal length pipe is better than unequal length of pipe. For unequal length of pipe, I dont really like the rumbling sound. It's more like subaru sound. The equal length the sound is much smoother and is not that disturbing. For the first month maybe the rumbling sound is nice but after that it's very annoying.

Mark 4: do you have a picture of how will you make the join section of the front and rear cylinder bank to the square shape turbo flange?

Ive never really been worried about sound, more how it performs. Oddly though, mine has a sound akin to that of a 5cylinder, which may I say always has, and always will, sounded better (its all about GpB)

[Mark 4]

Found a specialist aluminium welder today. Left him with a spare plenum which he is going to reverse for me. He has quoted fifty quid a pop which seems ok to me. Probs 1 to 2 hours of skilled work. Should have it back by the end of the week so I'll post up some pics then.

[foxdie]

Cool Mark, keep it rolling, here's some rep :)

[Mark 4]

. Log Manifold

The log type manifold is the most economical manifold on the market. They are almost bullet proof when it comes to reliability and they are the most compact manifolds available. Most manifolds you find on factory turbocharged cars are log type manifolds. This is understandable when you figure a manufacturer is all about reliability. When it comes to performance, a log manifold will leave you wanting. All of the exhaust gases flow into a common plenum where they often collide with each other causing a lot of turbulence before the turbo. This hurts the turbo’s performance and hurts the motors performance as well being that a log manifolds common plenum is so close to the other cylinders, it causes a lot of back flow of exhaust.
2. Tubular Manifold

A tubular manifold is one that is custom made for that particular users goal for the car. Most road racing cars will build an avg. runner, equal length manifold that will support great flow characteristics throughout the entire rev range. A car being set-up for drag racing will use a long runner tubular manifold, which will favor flow in the upper rev range. Tubular manifolds are VERY efficient when compared to a log manifold. They offer superior flow characteristics, and offer less back flow of exhaust gases back into the motor. Now for the negative……tubular manifolds are often prone to cracking causing them to lose points in the reliability column. For those focused on getting the most performance they can, a tubular manifold is a must.

[Mark 4]

Many thanks to Richard (Zentac) for allowing me to copy his pictures.

This is what we will be aiming for.

[Madhav]

Great stuff for putting in the effort with the single turbo kit. I purchased an 96 RZ supra in May last year and have since spent endless hours researching single turbo modifications, various models of turbochargers etc etc. Have been leaning a lot. Turbo technology in the USA is evolving constantly, for example Billet cores, triple ball bearing cartridges, oil-less turbos (no oil lines needed!!), extended tip technology, twin scroll turbos etc etc the list goes on and on. What this means is that you can now get a turbo that flows a lot more horsepower relative to its size, comes on boost faster and earlier in the rpm range and weighs a lot less.

Check out the new garrett GTX3076R (http://www.turbobygarrett.com/turbobygarrett/catelog/Turbochargers/GT30/GTX3076R_803713_1.htm) I think this is a great turbo for the 6A13 engine.

Borgwarner EFR turbos, amazing new technology. See here (http://www.youtube.com/watch?v=wfuE6xiij9g) Will save you a lot in terms of bov, wastegate, boost solenoid etc

Comp Turbos (Http://www.compturbo.com/pdf/CompTurboCatalog.pdf). A great mix of triple ball bearing, billet core, custom made in any size and spec to suit and at a very reasonable price (Can pick them up for about US$1300-1400) I like these guys because they can build it the way you want it.

Forced Performance GT3076R (http://store.forcedperformance.net/PROD/NTGT3076HTA.html) which flows more than the garrett GT3076R and comes on boost earlier.

Also the amazingly priced twin scroll borgwarner airwerks S200SX 75/70 (http://www.full-race.com/catalog/product_info.php?cPath=214_1167&products_id=1905)which once again has been shown to out spool the GT3076R garrett and flow more hp. Cost is only US$1k.

My point is dont be afraid to step out of the box and have a look at other brands than garrett GT series. Especially if they flow more hp AND spool better AND cost less or similar!!!

I have personally just taken out my old GT3582R garrett in favour of a new comp turbo, it is a 57mm and it will be tuned on Thursday. Will post up the results.

[Mark 4]

Thanks for the info Madhav. Will check out those links.

The Game's afoot !

The Game's afoot !

Sounds interesting/yes

[Mark 4]

Not really Andy.

Scored me a new daily driver, Vauxhall Omega 2.6 V6 auto, 2001, 60000 miles, 1 gentleman owner, bought it through his son in law who was a thoroughly nice chap (Airline pilot) as down to earth as they come. Who lives in a newly built "Grand design" which is off the scales.

Little old Galoon can now be rested for a while and will be used as a jig to fabricate all the bits.

It is stage 1 of about 4 or 5.

[foxdie]

Keep the ball rolling Mark :) looking forward to the results of this!

[Mark 4]

Should have some news in the coming days/weeks.

[zentac]

For that sort of power I would go with an internally wastegated GT27.

A GT30 will take you to around the 500 mark and a GT35 to around 600.

[Wobble]

any more on this Mark ?

[Mark 4]

Not yet Dave. Been really busy with work and sorting the house out ready to sell. On the brink of a breakthrough though so hoping to crack on with it. It will get done eventually though.

[Mark 4]

I know this is a long shot but does anyone have a dimensional drawing of the exhaust manifold flanges ?

[mpau009]

I have a drawing file for the td-03 flange on the turbo side of the manifold from doing my conversion, but not the block side as I reused the factory cast manifolds. If it is of any use to you, flick me a PM and i'll email it to you.

[ILLEGAL]

if you want the drawings to make some flanges.. what i done was use the gaskets as templates to make my flanges out of 10mm mild steel. and used steam pipe for the runners.
