What Turbo Is This?

[Griffin]

Yeah mate , nothing wrong with turbo, just needs a scrub. The whole point is i have an r34 gtr with around $35k worth of parts in the engine and supporting hardware.

The car this turbo will go onto cost $500. Sure i could spend 1500 to 2000 on a new turbo for awesome 'response' which is all the rage at th moment. That will defeat the purpose though of having a cheap daily hack.

This is the sort of thing i do in my spare time, i have all the other parts i need to do the job. It will be oh so sweet when i blow the doors off the average r33.

[paulr33]

i dont get it?

BNR34 + $35k in parts doesnt sound cheap

BNR34 would be able to blow doors off average R33 without a stupid turbocharger like that

not worried about reliability on your engine using this turbo?

and on a 2.6L it is really way too big

sell it or throw it out and at least get something pre this era, T04Z if you must have something big

[ARTZ]

you never watched Srapheap challenge??

This is the sort of thing i do in my spare time

Would love to have the tools and skills to do this sort of stuff, if i did my fairlane would have a turbo on it by now

[paulr33]

if it was a $300 datsun 180b or a $1000 R32 n/a sure

but a 34R with 35k of parts on it?

you do realise his not putting it on a 34 dont you?

[paulr33]

my bad

i thought it sounded odd

but its still a dinosaur spec

surely there is better sized units

[W0rp3D]

definately is better spec but as he said its a $500 sigma and he already has the turbo and other bits to use so he just wants to do it for shits n giggles!

Thats the impression i get from this thread.

* a 2.6 astron revs to around 5000 rpm, the turbo wont be oversped.

*im 30 yrs old and have been playing around with turbocharged cars since a lot of you guys were still on the tit! Hey you probably still are.....

*Has anyone here ever had any experienc with an old turbocharged 2.6 sigma or such? I think some of the knockers would be surprised with what they are capable of with the limited tech. available.

Want to see photos of MY 2.6 Sigma? Mine originally cost $150, $25k later, I can tell you, its still a piece of shit. HKS 3037 turbo, steam pipe manifolds, enormous cams, special offset pistons, C4 auto, big stall, surge take fuel setup, TR injection and an EMS. Originally we had a shitter with a free C4 and a free VL's turbo. After lots of "its only $500 bucks" here and there, it ended up as it is today.

All that work, and I blitzed it with my own hair dressers NX Coupe. The NX had a FACTORY STANDARD SR20DET including 2 inch exhaust, factory airbox and paper filter, 7psi and 120fwkw.

The Sigma still sits in my aunts garage, and I refuse to finish it. I leave it to my older (older than you) and much dumber brother. Its his problem now, and I have to continually convince him of not spending more money on it, in a feeble effort to save face to an originally 'good idea'.

You can call me a prick if you want, you can also talk about your age like it makes a difference, yet as far as I am concerned I am doing you one hell of a favor in advising you to quit while your ahead. A sigma is not an old falcon with a 4 litre motor. Its not even an old corolla..... Its a bloody sigma, with a magna motor.... It WILL cost you more than 5 grand to build. My turbo NX coupe costed me under 6, and I sold it for 7.

Take it as a grain of salt, as I'm sure you will. This is SOLID EXPERIENCED advice.

Further more, I will bring attention to the fact you will need:

A manifold

A waste gate

Exhaust system

Fuel pump setup

Intercooler and plumbing

Then have you considered management? Or were you going to force the carby? If you do, you will need to use a boosted application carb which will need to be boxed into the intake plumbing so it has equalized pressure OR you will need to have a suck through setup which will have your charge air run through the front of your turbo. Then you need to consider adequate jetting of the carb to accommodate.

If you were planning on using Magna injection, make note that the throttle body points the wrong way and your injectors are just big enough for the original motor. So you will need to cut off and move the TB and get a set of bigger injectors. You will also need a proper ECU to run it for you and will be hard pressed to utilise the stock item plus piggy back. The stock item shits itself with a pod filter and exhaust on a magna.

Once you realise this and that part of your concoction havent worked as planned, you will start to see things add up.

The original plan for mine was a backyard manifold manifold and crossover pipe.. The rest is history.

Like said earlier i have all the parts i need. Ive done exactly the same thing with a swb pajero except it runs an evo 6 turbo. Other parts i used were; evo 7 intercooler and cat converter, eco 8 mr bov, ts magna efi manifold, siemens 650cc injectors, sx fuel pressure regulator, surge tank with turbo supra in-tank pump fitted inside the surge tank, wolf v500 ecu, 3 inch exhaust with seperate wg pipe, rv4 galant waste spark coils, ts magna distributor, wrx inlet pipe, vr4 galant airbox plus whatever else i cant think of.

Everything was fabricated by me in my shed ie exh manifold, intercooler piping, surge tank, throttle body and thermostat relocation, inlet tract etc. I finished that 2 years ago and sold it to a mate 12 months ago without a problem.

Like i said its a hobby for me. I picked up all the parts for next to nothingor they came from previous half cuts or cars ive owned over the years and get all consumables from work so it costs me next to nothing. I get a kick out o fputting

things together out of parts laying around.

My age may not make a difference to anyone, just trying to point out im not a 15 year old time waster with no idea. The wole thing will owe me $2500 including rego not 25grand and counting. But thanks for the advice and opinions, im not afraid of some constructive criticism.

[Griffin]

Found out the turbo is a to4e03 from a 4-53 (212 ci) 2 cycle supercharged and turbocharged engine making 185hp at 2500 rpm.If anyone is interested. Thanks to Arthur.

[GTScotT]

Once you have it running PM me with a link to your works, I will be interested to compare it to my own.

The motors seem to spool turbos very easily and early in the rev range, yet make piss weak power.. It will act like it has a much smaller turbo than it does.

[Griffin]

no worries, not sure how long it will take. The pajero with evo 6 turbo makes boost straight away but hasnt been tuned fully yet. We will only run 10 psi. It made 152 hp at rear wheels on 5psi when we were getting it tuned 18 months ago and ran out of time. Ill take some pics of the setup if interested. should see him next weekend.

[Beer Baron]

I've got noting against the backyard turbo effort with free/cheap parts but can't help but think that that turbo which has a larger ex housing and wheel than the comp housing and wheel is going to be a pig of a thing on the astron donk.

turbos are cheap these days. there is no need to spend $2500 for a turbo for your banger. I reckon with $200 in your hand you could find something really good. a turbo that made 152hp in conjunction with a supercharger on a 2 stroke diesel that only spun to 2,500rpm is not going to do the business on a 4 stroke petrol engine running to 5,000rpm.

for the sake of a couple bucks by something a bit better. even something like the evo turbo you used previously would be a much better option.

[GTScotT]

Used evo turbos go for as little as 300, I bought the UPGRADED titanium version for my last evo for just $450.

I do recomend something larger for the astron though.. Something you would expect to be laggy on a 2L 4.

With the 'milder' of the cams I run in my Astron 2 my 3037 has full boost almost off the stall (2500), but only makes 150kw..... LOL

Looks like you've raided an archeological dig. What you have there is somewhat reminiscent of the paleoarchean era (circa 3.5 billion years ago; the average 0-100 time for a Mitsubishi Sigma). I recommend the Museum of Natural History in Oxford should you wish to attempt reconditioning it (highly recommended, as the CHRA has most likely become one with Gaia aka Mother Earth). Here's a more recent example from the triassic period - the similarities in housing design are striking to say the least:

[paulr33]

agree with beer baron and gtscott

at least get a smaller turbo, even an r33 std turbo would be better
