Tomorrow i get my new FMIC (Trust V-spl) installed and i am having a few thoughts about the increase in power.

It was Nissky's old car.

These are my current mods: -

RB20DET

R34 GTT Turbo (T3)

GTR fuel pump

Remapped computer

Apexi Super AVC-R (first edition, the black one)

2.5 inch turbo back exhaust

Air filter and BOV

Im running 2 levels of psi, 10.5 (.75bar) and 13.3 (.95bar)

Now my question is, with the new bigger intercooler, i should have 20-25kw more(correct me if im wrong) - will my engine/turbo be able to support these mods?

I really dont want the turbo to start leaning out and do rings :D

any help would be appreciated!

Cheers

Ive heard that installing a bigger FMIC allows the turbo to breath better, resulting in around 2 psi drop. Having a boost controller will keep the amount of psi at the same level it was before the bigger FMIC. Which should increase power levels.

Well that is what i have been told by people on this forum.

I agree with you rob77 when you say an intercooler allows you to run more boost safely in hotter temperatures (cooler air therefore less chance of detonation at the same boost levels). However I also thought that if you installed a decent aftermarket intercooler over the stock item and didn’t change anything else (boost levels etc) you would still get a performance increase due to the cooler and slightly denser air being inducted. Someone correct me if im wrong, only way to learn.

I think once u install the cooler because there is less pressure drop u will be getting higher boost pressures at the manifold, so more power. Even if u dont tuch the boost. Not 20-25kw though. Could be a reason.

when i had stock cooler, safc, exhaust i got 155rwkw with 12 psi boost

I then threw on a 600x300x76 cooler and ran it on the dyno again without changing any setting on the safc and i got 183rwkw.

The standard cooler is a pile of poo and does not cooler the intake air/not drop pressure as much as a decent sized cooler, ie cooler the intake air = more power.

Funny that the fastest r33 on a stock turbo was run by a guy with a stock intercooler too. talk to rev210 I think it was a 13.3 on the stock turbo, intercooler, ecu and on 205/55 tyres. According to you lot with a bigger fmic you should go faster because your making more power right?

Well if i cant beat my time, i will go he!!

I havent got huge kw's, and my terminal speed is not alot either, give me more top end please..

On my runs, my car was pinging badly in 3rd and 4th. If i can stop the pinging and get some more rwkw, a good time will be on the cards. Traction is the key and some quick shifts!!

why dont you try the water injection kits that are sold at MRt, for 1000 dollars the aquamist will qaurentee your car wont ping through the gears at higher boost therefor giving you more power...... just a thoguht.

    • 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?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
