Got sick of trying to load the photo's up so made a car domain page. Check it out it's still pretty basic but will progress as the build progresses.

Thanks for the offer Mike, might take you up on it later in the meantime gotta get stuck into the engine. Good to catch up with you guys too. Stripping the spare head in the weekend then the cam and pulley are off to get sorted so I can then start cleaning up the ports on it.

Cheers,

Dan

This forum doesn't seem to want to work with some URLs for obscure reasons that escape me...

You can fix em with TinyURL, though.

Your link.

...WTF? It's suddenly clickable once quoted...

lol that turbo is way to big for a 1.5 lol i wouldent even put that on me CA, how you are running gas, i recon full boost at 6700rpm

i would put a GT2876R on it, i have that on my ca and it its nice and strong, i have 15psi at 4100

have fun man lol

Stripping out the engine bay now. The intake manifold is off and most of the wries labelled up so i remember where everything goes. Turbo manifolds etc off. Some pics of the turbos side by side on the cardomain site.. Amazing how small the exhaust wheel is on a T2.

As a side note one of the blades on the T2 was nearly completely fractured which i had guessed from the whistling noise when spooling the car started making.. 12 psi might be too much for a T2 it turns out..

The turbo is a bit on the large side and probably in hind sight i went too big but meh.. it's really just a drag car anyway so i'm not too fussed if it doesn't make power till high up it is kinda the build i was planning anyways.

Cheers,

Dan

Mate, if you want a hand with anything just shout out eh! Ill be happy to work with you on anything from engine work to scrubbing dirty parts lol...

Thanks for the offer Mike,

At this stage i've got heaps of help it's time thats the tissue got any of that. Rotanats is fast approaching and it's seeming very unlikely it'll be reassembled run in and tuned by the 29th of Jan..

Oh well might just have to take it to a later night speed drag wars and save it for next year..

Plenty of time! I reckon you could build a 12sec over a weekend... as long as you have all the bits ready, as i beileve you do...???

Bolt on the boost maker, shove the forgies up the bores with shot peened rods and race bearings, New HG, Bolt on a worked head and exhaust, fuel pump/ surge tank. IC piping.... blablabla

The run in time could take a weekend if you are dedicated to it, and tuning another weekend.

200kw FTW!!!

THen strip all the weight outa that beeatch and go racing

Sounds so straight forward when you put it like that haha...

But it takes a whole weekend to just make a proper template for the flange for the exhaust manifold.

I'm just going to take my time so i hopefully only have to do it once.. Forgies.. um yeah too expensive just casties at this point in time maybe later on when it's dedicated dragstrip i'll invest the rest of the cash to try to make it indestructible.

As it is it's an expensive little exercise the 10g NZ i had is well and truly blown already.. without all the miscellaneous bits...

The exahust manifold is all tacked up and just need to weld it all together properly now. Next step rip the engine out and strip it, then working on the head to port it nicely and then reassemble.

Got a second gearbox on the way now that i'll lock up for use at the drags and rebuild that with new bearings etc.

With christmas fast approaching I can see nothing is going to get done untill january now....

see what anyone thinks of the manifold

hey amn i see your gonna run a link , do u think i would be able to grab a copy of your maps just as a starter

A whole lot of work in that manifold M8. Nicely done.

However, not dissing your hard work (and hard work it is...I KNOW) im a little mystified as to why you guys included such a large box shaped "plenum" thingy under the outlet flange??

Why would you design into there such a large volume space when the minimum volume and smoothen transition to straighten and maintain gas velocity is paramount?
Particularly so given you guys mention are using a turbo so large for the job.
In this case, you need as much lag reducing devilry as you can get!!!

For such a shitload less work a very simple and effective merge can been fashioned there to maintain gas speed, directin and keep the volume down as well as allowing for a wastegate outlet of any size that gives you wood:

This merge has been fashioned out of straight tube sections. You can use shallow angle elbows for a really neat setup.
This maintains as close as possible to minimum volume the collector diameter/header diameter merge.

Heres some unclear pix on how the merge is created using a piece of square tube as a cutting template and the finished pipes prior to welding.

Sadly, I cannot find some really clear pix I had showing how straightforward this setup really is to do. With a steady hand and a fair breeze, you can cut the tube sections freehand and grind flat later

Ha Yeah I know.. try telling the old man that though we had countless arguments about the benefits.. however if it proves to be too much of an issue then I can always change it easily enough. It's actually really interesting.. it looks like a huge box physically but really the interior dimensions wouldn't be much different to the 4 pipes merging together though i understand the mounting of the wastegate pipe and turbulence are less than ideal.

If you look down inside from the top of the turbo flange it's all relatively smooth. It was just for ease of welding it all together as we had to use the welder at the old mans work.

Appreciate the comments.

Hard work is right I recon once it's all nicely painted and tidied up it would easily have taken a week and it would take the same to do it again.

I guess i'll just have to suck it and see what it goes like. To be honest i'm really interested what it goes like.

As for the link I don't have a base map i'm afraid if you read the manual it goes on about calibrating the sensors then starting it up and getting it going. doubt with this engine your going to find a base map for it anywhere it's a bit old school now.

I've gotta run mine in on the standard computer first anyway so i'll be awhile before the computer goes in!

Nah, it wont be an issue at all.

Just about anything will work really, even a simple log works well enough but I feel if you have gone to that much trouble fabricating tubular headers
then doing it "right" right the first time would be worthwhile effort thats all.

Itll run fine.
Keep up the good work.

Progress continues

It's been awhile since I posted anything but it's still being going along quietly. Posted a copuple of pics for you all to have a look at. Radiator is now finished off and just requires final mounting. Exhaust is next up and then it's some work around fueling and wiring it all up.

Hopefully get it roughly tuned and running in the next month or so.
I decided to buy a wideband o2 sensor so I could try my hand at it as I'm not going to want to be sending it back to a tuner everytime I want to make a small adjustment.
