Hi my name is Mark I have a R33 skyline. upgrades are as follows

Built motor pistons bored to 40 thow. rods nismo oil pump hks head gasket, Race bearings. Main studs and head studs. stock valve train springs,cams etc. stock head.

HKS Gt 3037pro s turbo kit. from japan

HKS twin plate clutch

Power fc with hand controller

World Electornics Boost controller tbc-1 (best money can buy)

Full exhaust NO CAT ( 5 zigen)

Front mount intercooler

Z32 afm (30p00)

100mm intake manifold and T body.

Sard 800cc injectors and rail

Sard in tank 280 lph fuel pump

HKS M45 spark plugs

BF goodrich R1 tyres (Drag)

After market air filter

Ksport coil overs

Tuned by myself (wouldn't even call my self a pro tuner, understand a little)

Would anyone know how i can get a bit more power.? I live on a island (Bahamas) so we don't have a dyno over here. the road is our dyno.( the way it feels). I would guess i'm about 400hp to the rear wheels or less. I do all the work myself, I looked at this site and got everything i read about, Everthing was from this site ,and all you guys out there. Things that I wasn't to sure about I just got the best, that fits my needs (like the turbo disscusions)

I'm looking on making about 600hp any help would help.

The weakest part on the rb25det motor is the ring landing know matter what tuning you do thats the first thing to go.

I ran 25psi and it last for about 15 mins then, i did it all over again with another motor 15 mins agian. Now i"m running the same thing and i think i'm maxing out the afm. (CHANGE PISTONS GUYS DONT BE LIKE ME)

I'm realy interested in seeing how much the RB25DET can take after the mods.?

i'm planning on strokeing another motor with full racing head i must get 800hp plus with this motor. Planing on putting it in a 200sx check it out http://www.youtube.com/watch?v=9m2QV5QEK_U there is so much to talk about, but i'll take it a little bit at a time

my e mail address is [email protected] anything email me please

KEEP UP THE GOOD WORK EVERYONE.

so far negative is winning.

I'll stop talking and just do what i did last time

I don't think people were being negative bro. Just showing you some other sick burnouts because of your video. I'm also going to Japan next spring. I want to hand pick another car, as well as buy a bunch of junk for my R32 :worship:

This turning into a best burnout thread?

I can't help myself.

:laughing-smiley-014:

Lol that burnout was done on a GTS N/A (It has 4 bolts on the wheels).

Btw off topic here, how can you do a burnout with the car standing still like in the video?

When you press the brake, all 4 discs lock and thus no burnout.

How was that possible? Any links or items was used/installed?

Anyone knows how much power a rb25det with pistons And rods main and head studs and head gasket, can take or handle?

how much psi can the motor handle.?

Providing tuning is good.. More than your 3037s can push.

On the 25's the 3037's with cams typically max out around 320rwkw on 20-22psi. I haven't known one to push 300rwkw with std cams on PULP. No doubt there are some out there.

You mention its making 600hp in the vid you posted. Not a chance with that turbo and especially with it bolted on to the std exhaust manifold.

What afm volts are you seeing and at what rpm?

What duty cycle are you seeing with your injectors and what afr's are you running?

You've been stirred because you posted a burnout video and then claimed it makes huge horsepower.

Up and rolling vids of the speedo are a much better indicator.

"I would guess i'm about 400hp to the rear wheels or less"<----- mate he clearly said 400hp or less :whistling:. so before you try and make a cock out of him, might wanna read carefully :D.

also, the blokes been nothing but polite and has said nothing but praise this forum, so why dont u guys cut him some slack and either a) help him out and answer his question, or b) keep ur 2c to urself :)

the guy seems to do all the work/tuning himself, through reading etc. takes alot of guts to rebuild a motor and tune it on your own. so unless you are sum guru, i wouldnt mock him :).

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
