Garrett AiResearch TB03 L28ET turbo

[ol_skl_jp]

Hi

 

Does anyone have info on this turbo charger? I'm kinda new to turbo charging so bear with me.

 

I would like to know:

- The type of flange TC has

- Would it be classified as a small, medium or large turbo charger

 

Idea is to replace the TB03 with two smaller turbos for reduced lag, assuming that the TB03 is a medium sized turbocharger.

 

I havent done the maths for this yet, but is something i would like to do and having llots of free time next year (recently graduated engineer + no job = free time ).

 

**On a side note if anyone has a copy of 'Modifying Nissan & Datsun OHC engine' that they are no longer using, i would like to purchase it**

 

Thanks

Have you tried googling your exact title?

 

I'm guessing this is the turbo released on the L28 from factory. This would mean they'd be internally gated and small for an L28. This would also mean you would be stupid to put two 'smaller' turbos on to reduce lag when factory turbo engines already have close to the smallest turbo for the engine capacity to start with so lag is minimised. And why do you want to reduce lag when you don't even sound like you've driven this particular combo yet.

 

Do some maths first mate, then get on Hybrid Z where there are a lot more turbo'd L28's and see what turbos they upgrade to and from. Buy that book on ebay and read it. Then decide what you want to build, a drag car, street racer, track weapon, dyno queen, than choose your engine parts, intercooler/piping and turbo accordingly.

Graduated and no job?! I was snapped up a week after I finished my bachelor a few years back! Must be the economic climate..

 

Twin turbo on an L series is much more complex and expensive excercise compared to single turbo I would think.  Unless it's to gain attention or acknowledgement I wouldn't reinvent the wheel and stick with the trusty single....but that's my opinion....keep is simple.

I havnt graduated yet ill will be in December, should of said project meant to start next year. The idea is to be different, apply what i have learnt and make something.

 

rb30x its not like i havnt driven turbo cars, i have, just never owned one so never really had to do any homework on it .

Hey Sach,

I think I have a copy of the book for you...don't mind RB30X it sounds like he forgot to put his manners in!  The whole idea of this forum is information resourcing and social networking...so just keep on asking Sach!

Driving one and owning one is two different things. I stand by my comments with manners included. What are you intentions?? Do you already own a 280zx with a turbo L28? There's a turbo manifold on ebay atm you could use to charge a naturally aspirated L28..

Thanks rev i will, after all it is an open forum for oneto express their thoughts and ideas. I will also have to grab that book of you next time i see you.

 

I know this project will be quite expensive and is a couple of years in the making, but i would like to make a start on it as i have resources that i may not have access to in a couple of years (CAD and CFD modeling software). After i have designed a manifold and find that it isn't a waste of time and there are some noticeable performance gains i will go ahead and start collecting parts to complete the engine and build the manifold. Until this point there is no financial cost, just time.

 

Hmm intentions...? dunno yet

I've got a twin-turbo manifold laying around somewhere that I had made for my Z. I've since decided that the plumbing nightmare isn't worth the hassle, and will be going for a T3/4 hybrid of sorts...

are you going to loose access to bittorrent?

Reading too much Wangan Midnight back in the day, eh Ben?

[Ben]

Something like that! The ambition was larger than the common sense...

Software engineering students we're our bet friend while we were studying, they could get absolutely anything! You could work them up by saying "I heard <insert software that you wanted> was preeeetty hard to crack....". We had AutoCAD 2004 a day after it's release in 2003.....*cough cough*

For the uneducated (me) could you explain a bit further into the difficulties associated with your twin turbo manifold plumbing? Who hasn't thought about it, really

[WogsRus]

LOL, availability of resources, anyone for Cad 2011 beta?

 

LOL

Try jamming 4 induction pipes, 3 exhaust pipes, 4 water lines, and 4 oil lines in the engine bay, and then an inlet manifold.

 

It can be done, and has been done (and on LHD cars where the brake & clutch MC's get in the way too!). But I can't be arsed going through the trouble these days!

Turbos were a lot different back in the day too so if you wanted more low down response than your single offered you, putting two turbos on made a little sense. These days turbos have flash bearings not bushes (oil has chaged as well) and spool up so much quicker than the old ones. Spend your money on a HKS or Garret turbo like my mate did on his RB26 (twins) and you can hear the turbos spinning for at least 20 seconds after he shuts the engine off.

 

Plumbing is the pain in the backside however.
