post-17300-1156935427.jpg

I recently upgraded the lot from a bitza set up that started with a split dump on the standard turbo, then a front pipe added on later, it was good for 212kw but limited due to the 2 1/2" dump and the turbo at it's limit, mind you after 18 mths @ 16 psi it was still good, then at some stage I noticed it wouldnt boost above 15psi, Dan (3lit3 32) reckoned it was the studs snapped on the manifold, he was right but not quite as I had cracked the manifold as well. So I got a turbo with dump and a second manifold and installed the lot myself, and after a delay due to dyno comps, I had noticed that the cat was only 2 1/2" and with the bigger dump, the exhaust note quite louder as well, Right Price installed a 3" cat and resonator for 400 and I was off for a retune last night, it made 312rwhp/232kw @ 14psi easily, the turbo is a bit laggier but seems to be more gruntier down low, if that makes sense, the exhaust note is alot gruntier as well but the resonator took the harsh bark out of it. my next step will be the injectors, 500cc should do me.

Nice Terry...

I cannot wait to put my new hair dryer to the test...

In the mean time welcome to the 240rwkw club (well close enough).

Its at this stage you will find out how good your clutch really is and its easy to tell how good tyres really are...

I reckon the louder exhaust note comes from the larger turbo....as it has a larger discharge area?? Cause I changed nothing in the way of exhaust parts when I did my turbo and it came back heaps louder! Anyway that is neither here nor there! Good work Terry looks like it would be a fun drive now! I always love reading other peoples modification stories!

I should really write up my story some day! However I think there is a bit more necessary and unexpeceted work to be done before my story is over :O lol

And I hear you on the tyres point Col! All of a sudden I found out my old tyres werent that good! :/

Looking (and no doubt going) really good Terry! 240rwkW should make a nice, quick daily driver, any more and it gets impossible to put power down. I hear you guys on the tyres, after the last bout of mods I did on my old 33, the tyres I thought weren't too bad suddenly couldn't cope.

Nice curve on the graph too, it stays above 280rwhp for a fair chunk of the range :rofl: A set of cams might keep the power climbing for even longer too :)

With this wet weather lately I am finding the grip a bit loose with that extra power, the tyres were OK before, but now, a tap of the pedal gets me spinning too easily :blink:.

what turbo are you running now? they are decent numbers you are getting,very good. :)

The day I got mine back half throttle in 3rd would have me looking out the side windows instead of the windscreen lol...it is fun for a while :(

Nobody can identify the turbo, GoFastBits said it was probably a HKS prototype, it is a BB and has american threads in it, Dan reckoned it be equivalent to a high flow and Peter Woodward my tuner said it looked like one off a Rotar. Beats me, it goes good and the BB spool is goooood.

Yeah it looks to be something equivalent to a GT2535 - SB8032.

These are rated at around 400hp. But the results would suggest a bigger turbo just from the boost you are running...You are probably right about the HKS Hybrid copy thing.

    • I'm so far behind in the jobs I have to do at both work and home (including car) that I have become immortal. There's simply no way that I can die now.
    • Each to their own I guess  Me, I put just as much time into cleaning inside of the cars as I do on the outside As for getting wet, it is really no different than steam cleaning the carpets at home, apart from the cars carpet dries alot faster than the house, again, I only do it in the hotter months and leave the car opened up for a few hours As I only do it yearly, it is just before I do the diff and gearbox service, so I clean the carpets, then it's up on stands, wheels off, service, clean the undercarriage,  grease the bushings and do a nut and bolt check on everything  Disclaimer: I typically had all the time in the world to kill when I was working 🤣, so spending a full day or 2 cleaning, serving and "looking at stuff" was,  easily achievable, and a fun mental therapy day As for time to kill, I retired last Wednesday, so apart from my physical training, my days are filled with lots of random jobs around the house and garden...."Idle hands are the Devils something something" I am also buying a new house sooner rather than later, I'm actually looking at a potential property tomorrow, I'm looking forward to getting a car hoist as I'm starting to get to old to crawl around under a car, I can only imagine all the undercarriage cleaning and looking at stuff when that gets set up
    • Yeah, I'm not interested in wetting the carpets, and I don't care about brown dirt/dust that lives deep in the pile or underneath. It's not like I crawl around on them in my birthday suit or eat dropped food off them (because there is never any open food in my car). The seats are alcantara (cheap Chinese imitation alcantara, to be sure!) with barely 1" of foam pad behind the surface. That's not getting wet either. Any car that I would be happy to get the interior wet, I would not care to put the effort into.
    • We have one that holds 2.8L of water. On floor carpet that hasn't been touched in 2 or 3 years, will take a minimum of 2 fills of the tank to do a bedroom, and that's going AROUND the bed.   In the cruiser, I used an ENTIRE 2.8L tank, just on the front passenger footwell. But it had some fungus growing, and had been full of mud from being used as a 4WD for many years. I can do that floor again, and it will still pull mud out. However, the water now only looks dirty, not pitch black and leaving full sludge in the bottom of the tank it sucks back into. Oh, and, this is about a $1500 unit.
    • This is mine, works a treat for the cars, suction is good, I use the Bissell clean and protect stuff I have found giving it a good spray and light scrub with the soft brush on the head of the nossle for carpet, and a rub with a microfibre for cloth seats and cloth door trims, prior to another quick spray before vacuuming it up works the best @GTSBoy You would surprised on what it gets out of carpet and seats that actually "look" clean, I recommend that you test drive yours when you have a little time to kill, then post pics of the muddy looking water that I believe you will find
