Is doing a custom turbo really that hard ???

[ratbagpatrol]

monstor perfomance on e bay do astainless manfold for td 42 and tb 45 same man fold for around 350 with t 3 flange so iam told

[msjc38]

A zd30 patrol will probably nock off most of these back yard set ups.

[coxy321]

I suppose we're all lucky that this thread isn't about ZD30 hand grenades then, aren't we ???

JFYI msjc38, this thread is about TD42 turbo kits, so unless you have something constructive to say, go and pay www.zd30.com a visit.

ratbagpatrol, do you know if they make a mild steel/steam pipe version?? I'm not too keen on S/S.

I think there the cheap china kits, tho i have herd good stuff bout the turbos from some of the drift boys...

Found these while i was "busy" at work today:

Part 2: http://autospeed.com/cms/A_2605/article.html

I actually have the Maximum Boost book by Corky Bell. I have been thinking about making my own for a few weeks now, and i'm leaning more and more towards it as one of my mates owns a fabrication workshop = no labour charges and cheap materials.

Might even make a few if it ever happens.

no mate dont know you would have to get on to the i just know thay do as stanless steel one that what thay told me any ways

I have asked this same question on another forum, and almost was shouted down. ie: how dare I use my mechanical knowledge from pertols, and apply it to a diesel?

I don't see the sense in paying $4000 for a kit, that I can source myself, and pay under $1500. Call me sensible, but.....

It's alright for those that earn big bucks and have no probs paying this, I would too. Would be easier.

I have a 308 in my hatchback in the late nineties, had the crank offset ground, used mopar rods, notched the bottom sides of the bores and whammo! 308 is now a 337 with heaps more torque. That engine did over 80,00 kms and a quarter mile in 12.4 in street trim.

I'm not after that for my gu dx td42 with 335,000, but I think I can get a manifold for $185, GT28 (garrett) $450 (reconditioned), father in law is diesel fitter, so he's got the fuel pump sorted and any possible rebuild. Couple of more bucks for piping and hoses and I think I'm done.

So can we have more ideas to create our own setups? It's not that hard, or is it? I've read some flamin' good ideas here, and that's how we all can benefit!

[coxy321]

Sounds like you're on about the same frequency as me monkeycritter. I reckon i could do one for about the same cost.

The biggest issue i have is sourcing stuff like buttweld sections, turbo gaskets etc. as i live in a small town.

I might start gathering bits over the next few months as funds allow, and work my way towards building a kit. I have access to all the equipment to build it, so its just a time factor.

The other issue was that i'm waiting on a "supply only" quote for a turboglide kit. Their advertised price is $3650ish, fitted including exhaust - which is bl00dy cheap.

Time will tell which way i go.

honestly $4000 for a kit in my view is abit of a rip-off for what is really in the kit..

basically how I see it all you need is the exhaust manifold (im sure denco/DTS etc can supply them im guessing for around the $250 mark

then all you have to do is find a turbo with say a T3 front and as long as its got a small exhaust wheel (nothing over .60 exhaust wheel) your in business even a GT2530 should be reasonable size $300-400

or you could pick up a turbo from a late model patrol..

the more bigger the A/R on the exhaust wheel the more lag you will have, all depends when you want it to come on boost..

while your at it grab a intercooler from a WRX or simmilar bit of stainless pipe and silicon hoses $500

then all you need to do is wind up the boost and fuel and keep and eye on the pyro

all up you would be looking around the $1100

and you will be cranking out alot more power than what a stock DTS/Denco kit could offer for $3,500-4000...

[GQ4.2]

just another thing you could also use a stock turbo from a RB20/25/26 motors which would bring the boost on early, BUT with them you are only limited to 15psi max as they run a ceramic exhaust wheel and will overspeed and fall off...

[monkeycritter]

Yep, looked at the GT2530, GT2860rs (disco potato), GT28 and roller bearing T3. I can't remebr which kit, AXT I think, they provide a T28. This turbo is standard. Know a guy that works at MTQ (the same mob that had the article about improving the factory turbo for bout $2500!!!!! he told me that most commonly, T28/T3 tdo4 is good for average joe with little lag. Want the bigger power/comp truck/always towing the camper, go the gt2860rs or the tdo4h straight from the wrx. Only prob there is the manifold bolts don't match. So buggered there?????

Look, it's just like paying $2000 for a new set of coopers, and I buy a set of federal tyres for $1200. We know you get what you pay for. We just like being able to actually stick our heads, and our hands in the engine bay and know what is wrong, and are able to fix it. Other wise I'd have bought a zd30????

If we wana build our own kit, we will. Don't mock us! If it breaks, hats ok, I don't know how many times I blew a diff, and got home, got new parts and fixed it, for less than the price the "other guys" paid to have it towed home, because they are still trying to find out where the "polariser" is!

[GQ4.2]

im not mocking you mate im looking at doing a custom turbo setup

[monkeycritter]

Oh, I know. But there are plenty out there that have. Sorry, just sour grapes.

Sick of being told, "why risk it, $4000 isn't that bad, why not use something that has been tried and tested".

I/we don't fit in a box, so I look for round pegs! Just like you do! Lets hope we get what we want!

[coxy321]

For the amount of cheap, cheap, nasty "home made" turbo kits i've seen over the years, i have complete faith in myself in regards to building a kit. Hell, i've done two oddball conversions already (EA falcon about 6 years ago, and Datsun 180B 2 years ago).

The only issue i can see with ANY of these DIY kits is the fuel pump. Apparently you can get your pump modded with a genuine nissan boost compensator and calibrated for about $800. Or so i have been told....

I'm waiting on payment for a little cash job atm, so i might start getting some bit organised with that money. Wifey tracks all the money in the acounts

First step is getting header "blanks" cut to give me a starting point, and a GT28 ball bearing mounting flange to give me a finish point for the manifold. Baby steps....

you would be talking about a "TD05H", not a TD04 or TD04L, both the td04's would be making boost at idle on a 4.2 litre.

im planning to turbo my 93 RX 4.2 petty/lpg, allready have the flange thanks to the Hitech headers that came on it ebay t3/t4 turbo is what will be going on it, either a FMIC or a wrx top mount or an rs liberty WAIC.

ive got my own tig welder to use too

[evo wagon]

you can also get the tdo5h off the mitsu evo engines or gsr engines. these turbos have the square looking flange on them so would be better suited than the wrx version turbos which have the triangle flange.

i am looking at doing a turbo setup on the budget for my gq td42.
what i have come up with is the cast manifold from mtq for 480inc which i thought was pretty cheap saves making one up. now that manifold has t3 flange on it so going to track down a rb25 skyline turbo and wack that on. front mount cooler for $150 brand new and that should do. plus exhaust and other pipe work required. once tuned should produce close to 145hp at rears.

[coxy321]

$480 sounds pretty cheap for a manifold......

Custom=
- $30 for header blank
- $30 for turbo flange
- 18 buttweld sections (three per cylinder) @ $8ea = $144
- $30 Grinding/flapper discs
- $40 for a slab as payment for workshop/welder hire
- $50 for getting faces squared at engine builders

TOTAL= $324 , which doesn't inlclude the 10 odd hours of my time.

Coxy

[evo wagon]

thats what i thought by the time you add up the labour to do it its easier to just buy the cast one. let me know if you want one can organise it for yer.

[coxy321]

Why dont you hit them up for a group buy price?? How many TD42 owners would be interested??

Coxy

[evo wagon]

yer that sounds good so how many ppl want them?

[coxy321]

I reckon you'll be better ofs starting a new thread "Group Buy for TD42 Turbo Manifolds".

Maybe see if they can supply the inlet manifold crossover pipe/plate too??Only cause its a bastard to fab up, when it'll probly only cost $100 to buy.

Maybe also put up a tender in the new thread for an OL member to supply the goods. There's a few members that work in the industry that might be able to get a good deal.

Coxy

Count me in!!

[GQ4.2]

I got a reply from turboglide for a manifold for a TD42 - $480

either way i'd be interested in a group buy if it worked out cheaper

[nastytroll]

PM oondy, he does MTQ/DTS manifolds

[coxy321]

Coxy, your a ledgend! I wish I hadn't just had my Bathurst tickets come out of my bank!! Damn!!!

[coxy321]

And that is why no cut-off dat is set yet, so you can spend your next pay-cheque on a turbo manifold!
