hi guys, u may think this is a noob question, but i have hit the power wall. i would like to get some more power out of my r33 gtst. atm it has an upgraded t4 turbo, ssq bov, 720cc injectors (dont ask, dont know why they work), Bilstein heavy duty suspension, front and rear strut bars, nitrided crank, fmic, 3" exhaust and im probably forgetting something.

the turbo will soon be upgraded, a screamer pipe, safc and a tune/remap are on the way. i am also thinking about a z32 afm.

i would like to know from your experience and expertise, whether there are any good mods i can do with a budget, to gain more power, atm the clutch can handle 420kw.

i am probably pushing 190-220kw, which is just a guess atm, will know more after dyno.

furthermore i am thinking of investing in its support systems later on

any and every piece of advice is appreciated thanks.

How are you running 720cc injectors without management?

You dont have management listed as a current mod, only a future one... so 720's = impossible :)

And i also dont get a nitrided crank either!

For basic mods, see here:

For more results, so you can relate that to parts

http://www.skylinesaustralia.com/forums/in...showtopic=55845

And a couple others

There are but a small few of the good threads you can find :)

Also setting a budget for everything helps to get more accurate responses

cheers all the mods bar the fmic and strut braces have been done by previous owner. ive only had car since january.

i will definitely check out ur links, budget is about $3000

You could have made 200rw will stock turbo and stock injectors - sounds like what you need is a power fc or somesort of full engine managment to get what you have running properly and efficiently.

thanks heaps, the responses i have been getting is to invest in electronic support systems.

i will definitely have a look around.

no, its a 5sp manual

thx

Yeh definatelly get an ecu and if you can the power fc is probably your best bet - hard to find nowadays though. That way you can tune it and make the most of your bigger turbo and injectors - should have nice power then. :)

Stock turbo

3" turbo back exhaust

Intercooler

Fuel pump (eg: bosch 040)

and something like 12psi should get you anything between 190rwkw-210rwkw depending.

It wouldn't hurt to get an SAFC II, fuel only computer, to keep the fuel at a safe level and AFR down to a safe level.

With a tune on the dyno you can push over 200rwkw+ on stanard ECU running the above + SAFCII.

But depends how much you want to spend. Since you already have a T04, get a fuel pump, and an after market ECU and get it tuned. You will make some good power.

Hope that helps.

Thanks,

Abu

definitely thanks. thats perfect i want to have about 250kw if possible, and maybe more, just to beat a few mates.

at least on this forum i can listen to people that have done it before, some engineers i have questioned dont know shit about imports.

once again thanks, i will look around for a better ecu/ power fc and a fuel pump.

I still dont understand how you have 720cc injectors with a stock ECU

theres alot you may not understand, but it works and thats all i care about, that is one of the reasons i purchased this particular car.

all those extras with no ecu upgrade.....

you should be upgrading ecu if u go down the bigger turbo/bigger injectors road.....

yea, ive been thinking about it for a while, im just waiting for a good unit to come onto the market.

I know enough to know 720cc + stock ECU = no chance

:laughing-smiley-014:

Yeh doesn't make much sense, any sense really, even with a simple fuel computer they would flow way too much and the ammount of correction applied would be astronomical. Perhaps either they are not 720cc or it has some crazy re-mapped jap ecu that he is not aware of...

hey guys, just throwing it out there,

does anynone know a ball park figure for a full tune?

any suggestions would be helpful

Depends what your tuning...

safc around 150 -200

Power fc around 400 - 500 perhaps, each car / ecu is different.

I'm contemplating a power fc or if i can't find one maybe I'll go with emanage ultimate. :) safc has gotten me to 195rw so far so its doing an alright job on a reasonably safe tune i.e between 11.5 and 12 afr. :)

safc around 150 -200

k sweet, i'll tell a few mates, also-im talking too much

but when i get all these mods done, will it be safe to drive around for 1-2 wks untuned. until it is tuned?

cheers

    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
    • Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
    • Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.
    • also possibly backed up to my filler and shat down it! 🤣
    • Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
