IF his is making 165rwkw's at 15 psi with 35 baja claws how will yours make 185 with only 6psi?

Any one got any tips on where to get a td42 turbo exhaust mainfold?
priced a genuine nissan manifold today and they reckon $800 ex japan.
any idea's?



cheers wes

Does Ice Performance have a website ? All I got was http://www.iceperformance.com.au/

Is this ICE as in Ignition Components Engineering (At least i think thats what it was called)? You guys used to make Custom Ignition Leads?

zac zec,

The gtr inj fit straight into the tb42e rail(gotta luv nissan), the gtr rail would be too short anyway.

Dont need rising rate reg, would rather use big enough inj in the first place. The only time you need a rising rate reg, is if you are extending the flow of your current inj.

I replaced the p/s cooler with a proper cooler and just mounted to the side of the i/cooler.

Not a big fan of water inj in any application. I know heaps of people use it, some with good results, but i cant offer any real experience. I do think it creates another possible problem if it fails half way up a long hill and you dont notice etc.

cheers

tuf045, I can supply you a manfold for $550 + shipping. Would take two days.


blkmav, Thats the extent of the website atm. It is going to be finished in a couple of months.

RUFF, nah but we are just around the corner funnily enough. We mainly specialise in late model japanese import turbo cars, we offer a range of services from engine building, in house dyno tuning through to servicing etc etc, but ive always loved 4wheelin so i figured may as well merge the two.

cheers

Thanks quadcamshorty, you make a good point about water injection, i want to keep it as simple as possible. Dont want dramas.

nigel
you tuned my black r33 with hiflow & pfc on a rainy cold may day
very very happy i love lighting tyres
i will promote your work down this way, people need decent tuners instead of people with a dyno and thats it
ps may need to tweak some things with pfc gets a splutter up high like duty cycle maxing out? dunno any thoughts? not really the right forum for so called rice cars but any ways keep up the good work
looking to buy a gq lwb and do simmilar conversion i
just gotta get some bits together ie turbo,fuel pump again hey do you think a standard r33 turbo one would still work ok?? your just using standard well pretty much bush T3? cos i can get hold of one of them how good is teh autronic wiring loom just find teh wires you dont need and cut em out how easy is that for an install good thinking by them any way keep up the good work ben

Also, would this installation lend itself to LPG or is it definitely petrol only?

RN

mgundle, give me a buz and can talk over the gts, sounds like something small anyway.

The standard gts turbo would be ok, it would spool up so early and still make ok power. Just depends what sort of power your after really.


roadnazi, Yeh you could definately have this setup running lpg. You would need to run the gas research gear, which isnt that expensive considering the cost of petrol atm. The only problem would be achieving a good gas and petrol tune setup(could be done tho), as obviously you would run out of gas alot in the bush.

Just done a TB42E turbo convert intercooled 8 psi std ECU with haltech interceptor , 1st run 173kw at tyres 33" . Still tuning , has 417 Ft/lb torque.

diesel low mount so I still have heater and A/c pipes. T3/T4 turbo .6 compressor, Big front mount 550 cc injectors, rising rate regulator . have pics soon . Getting dyno sheet print out.

How much boost are people running b4 decompressing. Ive heard that they run up to 18psi without doing anything Are those injectors out of an rx7? Did you have to cut the factory plug off and crimp on new ones.

Just done the same thing want to run 15psi. What do you rekon about this much boost?

Cheers

Why so much boost when you can get good results with 8 psi , IF YOU KNOW WHAT TO DO. The 550 cc injectors don't just bolt in you need to modify the pintle caps and the plugs. There is no need to decompress these engines as they have a factory comp ratio 8.5:1. They just beg for turbocharging.

why not? More Power. Yes to fit these i had to bore out my fuel rail slightly and change the seals for different thicknesses. So 15psi sounds safe without decomp?

Thanks for your help

Seen them run at this Ok. Just watch your A/F ratio and timing in the top end. What fuel pump are you using? You will need an in tank unit rated at over 500Hp to keep up . What intercooler / turbo do you have?

Im running 2 fuel pumps. An internal vl pump for a pick up to my sugre tank(approx 2.5ltr) and a vl turbo pump to feed the injectors, ive run my fuel return back into the surge tank to try and keep it as full as possible. Running an air to air intercooler headlight to headlight. Turbo is rx7 series5 with my own custom made manifold top mount. Im also running a bigger radiator and a big oil cooler that i have munted behind the tray with a thermofan that cuts in and out on a temp switch. I went the way of genuine AU thermos dont know if this is good or bad yet as i have heard so many different stories. Ive wired them up so they run low (both of them) all the time and the computer will swicth them to high when needed, also have an overide switch so i can turn them off completely if needed. My other worry is my clutch, I had to change it when i did my original setup but now im wondering if it will hold up to the new setup. What clutch r u running? I put in a daiken extra heavy duty diesel clutch, Had an rpm heavyduty b4 that and would just slip on boost.

I think you will run out of fuel with those pumps , allthough your surge tank may hide the fault for now. Under a long full noise pull it will empty the can but maybe not enough to create flow problems.
The turbo you are using will be flat out flowing enough to produce 15 psi at full revs I think you will find the boost will drop off at high revs.
Asuming its a standard rotory turbo , are there any numbers on it?

Spoke with the the main man over here in the rotary department and he says that they run 15psi on a rotary no probs so shouldnt see a problem. Only if the motor will hold up I said it shouldnt be a problem basing it off what people are saying. How sure are you that it will hold up for a long duration? Dont want to blow things up. Will limit revs to 5700. Dont want to rev it past this anyway. As for the fuel pump setup ive got them now so i will see how i go. No big drama to change them. I let you know how it all goes. Wont get it to tuning for another few weeks though as i had a crazy idea and decided to pull all the wiring out of the car and re-wire it (so much sh#t that is not needed). Bigger job than i thought

By the way, thanks for all the info. I take it all on board. Keep it coming. My biggest concern is the strength of the motor. Id be lucky to do 5000k's a year in it though (hard k's though). I read about alot of people running up to 20psi without any mods but how long does the motor last for

Cheers for the help
In the dark over here in Perth

The turbo may produce 15 psi but won't flow enough air for the engine, a pump only creates flow its restriction that creates pressure. The swept volume of the rotary is probably half that of the patrol. You would have to make the turbine work twice as hard to fill the patrol engine to 15 psi !!! Get some dyno time and an inlet temp probe , start at 8 psi and increase from there and watch the temp. There will be a point where the temp rises dramatically, this is where the turbo has lost its efficiency.
It may continue to make boost but will be overworking the turbo , and creating other probs due to high intake temp.

That definitely makes sense. Ive spoken to the tuners and they will run the turbo to max efficency, as you say its pointless going past this. I would of thought though that because rotarys put out so much air that a patrol reving to 5700 would be similar to a rotary reving to 9000+. My plan was always to max this turbo out (i thought 15psi?) then go from there. In the long run i want to run a gt series turbo when ive got the spare cash. We'll see what happens

Would this turbo setup be suitable for the TD42 also? Obviously minus the ECU and injectors.

Pricing?

Goe with the low mount manifold off TD42 and skyline RB25DET turbo and leave it at 8-10 psi MAX or

The RB25 manifolds are different stud pattern to a TD42/TB42 head, right?
Sounds like a dumb question but you never know, I was supprised to when I found out TB42 and TD42 were the same.

Whats a fair price for a turbo?

rb25 manifolds are shorter as well as different stud patten

I'm doing this conversion soon......my standard EFI fuel pump has just about shit itself. Instead of just buying another factory pump can i get another (higher flow rated) pump to bolt straight in? Any ideas?


Jimmy

does any 1 no about turboing a rb30.on gas and petrol in a nissan patrol

Yeah you can go buy everything out of a vl commodore and bolt it on!
