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

Sean

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.

      I dunno about that as a blanket statement. Pitwork is Nissan's "Nissan genuine" thing, and for stuff like timing belts, I have found them to be excellent. Of course, for things like oil filters, you always use proper trusted brands anyway, not whatever the OEM has taken to using.

      Ahhhh... If you were putting 12V to the led in there, that's likely made it very unhappy. Chances are how you put power, was 12V across an LED that's meant to only have about 20mA through it at peak, and a forward voltage of about 1.8 to 2.4 volts. That circuit is likely only a 3V3 circuit, and will have a resistor in series with the led too. That's my guesstimate on that light, without having touched one.

      Another vote for installing them and see how you go.  I mean, you already own them, why would you not fit them?

      I have had too many of those over the years, my cars have a toolkit or at minimum a cheapy multi tool thing because its too easy to be snookered by some stupid plastic clip that stops you checking the battery terminal isn't loose.

      Basically, if there is a part# on the nissan catalogue, it is a genuine part. There is a thing called "new old stock" which is stuff made years ago but never sold (or landfilled), but it is super hit and miss what you can buy. Other than some expensive Nismo stuff there is nothing new being made that suits these cars. The only time to be a little careful is (mostly in the US I think, but maybe Japan too), Nissan started rebranding some cheap crap maintenance parts like oil filters as "Pitworks"; stay away from them, if you are buying cheap just buy whatever the local car parts shop carries The three part numbers have an explanation on Amayama: 0V005 is auto, base style 0V015 is manual 0V505 is auto, hectic momo branded ones, maximum F&F points there!
