JET 31 - Why dont u want maximum torque? Thats the funnest part, yes its more det prone there but if the fuel is good enough then there is gains to be had, then let the boost build to redline and make crazy power figures.

If only...

I was just talking about using 98 octane, not unlimited octane, would be a nice old juggling act with timing on 98..lol, i have had freind long ago just do this with WI, standard T25G;s

on Sr20...25psi coming on and through midrange and 16- 17psi up top which is all it have it give, 111-113mph traps on a T25G in a silvia ..not bad..

cheers

Hey guys

I'm working on a 250kw RB25 setup

Tossing up between the ss1pu or the ss1.5

It's going to be a street car and I want something that pushes you back in your seat and makes you hold on

Makes power early and can hold 250

Read the charts with the differences between the 2 and saw the 1.5 made better numbers on lower boost so I guess this would be the way to go?

What's the difference in the 2 other then the $250 price difference?

definately gets the 'whoa!' feeling :)

Ur on ur own with that one. I see it as even if u have the power to break traction, with the correct throttle control u can be just as fast

Not with a Gt42 and 400+ wkw and 200rwkw of that over say 500rpm of the powerband coming on ..,lol its so toey it impossible to control and the faster you go, the worse it is, because you are applying more load and need far , far less throttle input, all you can do is setup sus and tyre selection

cheers

Thought i would chime in with my findings so far on my ATR43G3.

Firstly, hats off to Stao and his mechanic that can get one of these suckers fitted in 4 hours!

Took it for a little drive around the block. Using 1/2 throttle, i got it to 4500rpm 1 or 2 times just to see whats up. A nice spooling sound and exhaust note is whats up! It seems to run/idle the same as before (tuned ECU), but i know not to give it the beans until its tuned properly.

Changing injectors tomorrow so if all goes well its getting tuned on monday.. Then drags on wednesday. :devil:

Would be good to see some mph from these things!

You're not gonna try to drive it to Ovaboost after doing the injectors are you??? I'd bring a couple sets of replacement spark plugs if you are :P

Also keen for results from the tune/drags :D

Lol, i've since decided to change them in their car park. :thumbsup:

assume the wheels, shaft, bearings, and housings are re-useable. That will cost you $400. If every thing are gone and only housings are good then its not suitable for rebuilding. That will cost you $800 which is high flowing to 2860rs specifications. So the worst case scenario will cost $800.

Hey Stao,

What would be the highest figure you could expect from a SS1PU without putting to much stress on it?

I see its rated to 470HP which if I am correct is around 350kw

I am looking to purchase on this week.

Thanks

SS1PU makes around very responsive 260rwkw mark running 18~20psi. 22psi max it out at 280rwkws which is the most this turbo can do internally gated. This turbo has no issues handeling boost.

For the GTiR rebuild, $400 covers: 360 degrees thrust bearing, bush bearing, collars, seals, sand blasting, balancing and assembly.

Drop the turbo in when ready. I will need to pull it part to give you an accurate quote.

Some Modifications that I've done to a stockie R33 21U turbo:

Would be awsome if I can crack 300rwkws with it internally gated on pump 98. :D

Turbo's installed today:

Looking pretty stock :D ?

Initial test drive, it builds up boost very quickly. Dyno tune due in soon.

    • The engine stuff is Greg Autism to the Max. I contacted Tony Mamo previously from AFR who went off to make his own company to further refine AFR heads. He is a wizard in US LS world. Pretty much the best person on earth who will sell you things he's done weird wizard magic to. The cam spec is not too different. I have a 232/234 .600/603 lift, 114LSA cam currently. The new one is 227/233 .638 .634. The 1.8 ratio roller rockers will effectively push this cam into the ~.670 range. These also get Mamo'ified to be drilled out and tapped to use a 10mm bolt over an 8mm for better stability. This is what lead to the cam being specced. The plan is to run it to 6800. (6600 currently). The Johnson lifters are to maintain proper lift at heavy use which is something the LS7's supposedly fail at and lose a bit of pressure, robbing you of lift at higher RPM. Hollow stem valves for better, well everything, Valve train control. I dunno. Hollow is better. The valves are also not on a standard valve angle. Compression ratio is going from 10.6 to 11.3. The cam is smaller, but also not really... The cam was specced when I generated a chart where I counted the frames of a lap video I had and noted how much of the time in % I spent at what RPM while on track at Sandown. The current cam/heads are a bit mismatched, the standard LS1 heads are the restriction to power, which is why everyone CNC's them to get a pretty solid improvement. Most of the difference between LS1->LS2->LS3 is really just better stock heads. The current cam is falling over about 600rpm earlier than it 'should' given the rest of my current setup. CNC'ing heads closes the gap with regards to heads. Aftermarket heads eliminate the gap and go further. The MMS heads go even further than that, and the heads I have in the box could quite easily be bolted to a 7.0 427ci or 454 and not be any restriction at all. Tony Mamo previously worked with AFR, designed new heads from scratch then eventually founded his own business. There he takes the AFR items and performs further wizardry, CNC'ing them and then manually porting the result. He also ports the FAST102 composite manifold: Before and after There's also an improved racing crank scraper and windage tray. Helps to keep oil in the pan. Supposedly gains 2% power. Tony also ports Melling oil pumps, so you get more oil pressure down low at idle, and the same as what you want up top thanks to a suitable relief spring. There's also the timing chain kit with a Torrington bearing to make sure the cam doesn't have any thrust. Yes I'll post a before and after when it all eventually goes together. It'll probably make 2kw more than a setup that would be $15,000 cheaper :p
    • Because the cars wheels are on blocks, you slide under the car.   Pretty much all the bolts you touched should have been put in, but not fully torque up.   Back them off a turn or two, and then tighten them up from under the car with the wheels sitting on the blocks holding car up in the air.
    • Yes. Imagine you have the car on the ground, and you mine away all the ground under and around it, except for the area directly under each individual wheel. That's exactly how it'd look, except the ground will be what ever you make the bit under each wheel from
    • Yes, if you set the "height" right so that it's basically where it would be when sitting on the wheel. It's actually exactly how I tighten bolts that need to be done that way. However....urethane bushes do NOT need to be done that way. The bush slides on both the inner and outer. It's only rubber bushes that are bonded to the outer that need to be clamped to the crush tube in the "home" position. And my car is so full of sphericals now that I have very few that I need to do properly and I sometimes forget and have to go back and fix it afterwards!
