hey guys, ive got a R33 gtst S1. im looking to start modifying the engine to try gain a bit more usable hp, just really unsure on where to start, what to get and where i can get it and cost of course.

if people could perhaps post up the sort of things i should be looking into upgrading that isnt going to kill my wallet and give me a bit more power without stressing the engine that'd be great.

cheers =]

Have a read at this basic guide on moding a RB25DET. LINK

Basically for power, turbo back exhaust should be the 1st upgrade, followed up a intake upgrade, then inter-cooler & boost controller & some kind of engine management.

Intake, Exhaust and Intercooler upgrade matched to a Nistune (Z32) ECU update will give very good performance gains at a good price and wont kill the bank or the car.

How about an Electronic boost controller also? ;)

sorry guys umm this is basically what ive got atm.

turbo back 3inch? exhaust its big and loud anyway

boosted to 10psi with a turbosmart boost tee (doesnt really like it alot so i never actually boost it that high)

Fmic

pod filter

a/m Fuel pump

Short Shifter kit (wont make it faster but its still an upgrade =P)

thats bout it, other than that she's a rock :D

not really sure on my budget, im not rich so cheapish but still decent would be nice lol. to give you an idea im a 3rd yr apprentice mechanic so not really on the big bucks.. im not so much into increasing my top end as im not into the whole go super fast idea lol, i'd prefer to look after my engine, never really rev over 3-1/2>4grand tops before changing, i'd much rather more low/mid range power which would be super usable to me.

Moving beyond the limit's of the factory turbo is going to start costing over the $1000 mark and without getting the proper supporting mod's 260hp running the stock turbo at 12 psi will be much better to drive than 300hp upgraded turbo running low boost on the street. I'd suggest getting a fuel pump next as the stock one's are getting old and your power would be reasonably higher than what is offered at stock with the current upgrades.

Take care of the handling and braking before power ups.

From what I can tell from his subsequent posts, he's looking for a bit more torque in the low end (2k-4k rpm). I'm not really sure what you do to get that, besides upping the capacity of the engine or adding more cylinders. :)

[but then again I know shite all about engines :(]

bigger turbo, injectors, coilpacks, ecu.

How is that going to give him more torque down low?

And why would you get new coilpacks if they stockers aren't stuffed?

If you want more torque down low, then really, build a cheap 3L :thumbsup: Being an apprentice mechanic you should be able to do it yourself.

It's going to increase the torque down low and across the bandwidth, use some cam gear's effectively the power should come on earlier (TRUST, HKS or OS GIKEN). Changing coilpack's is a good idea with the age of nissan skylines now, very few set's would be operating to there maximum potential and aftermarket one's are cheap and good value. Building a 3 litre properly without using budget or used part's will not see any change from $5,000 so that sort of cancel's out cheap performance upgrade. In a perfect world stroking her would be sweet and achieve that torque goal.

Good luck with the upgrades dude, hopefully you have obtained some good advice.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
