Apexi Turbo Kits For R33

[Munna1]

Thanks again price works out to be a tad over 2500 delivered very resonable, I sent them an email and it comes with everything need to bolt onto the stock manifold and standard size dump pipe.

cheers

Just remembered about a article I read once in a HPI mag about a GTS25T with a apexi turbo. Had a look before and found it, issue 31 yellow r33 on the front. Using this turbo with 1.3bar of boost 268rwkw was produced. Mods incuded all the usual stuff plus light head work and step 1 256 tomei pon cams, the NVCS disabled and cam gears were used instead

interesting,sounds like good power tho,wonder what it would be like at 22psi , if it would run that high

I ordered one of these yesterday...

[Munna1]

Im very interested to see how it will go mint, if I had the cash to upgrade my turbo I recon this is the one id get to. What other mods do you have / plan to have.

cheers

Currently have FMIC, full exhaust with hi flow cat, pod filter and power FC.

Will be adding poncams, fuel pump, injectors, Z32 AFM and apexi super suction (basically steel intake pipe) kit to the list before getting it all tuned along with power FC boost control kit.

Apexi rate the turbo at 375hp (from memory) or 280kw, but I will be happy with around 250kw.

That is the exact setup mod for mod that I was thinking mint, the same power target (250rwkw) too. Tomei poncams where my pick as you will be able to keep the NVCS for better midrange. If this setup makes the power it would make it the perfect street setup for a RB25 in my opinion.

My only concern is the amount of boost required to get to 250rwkw id estimate around 1.3 bar. A question for the experts, would we need a thicker head gasket to lower compression? Or will this boost and power level be fine with stock internals.

Hopefully you could get away with this without the thicker headgasget as response, spool time and off boost torque would be sacrificed.

Keep us posted mate

cheers

[Bliksem]

Haha, funny that mate!

Our cars pretty much look exactly the same too.

I'll keep you updated anyway... Greenline emailed me about an hour ago to let me know the turbo kit will be shipped out in the next 7 days...

[gtst25]

its nosing off past 6k

i dont reckon it would go past 250kw

No highflow cat and a rich tune will make it nose off after 6k.

There is definitely some restriction somewhere as my car was making exactly the same power at 16psi as it was at 14psi..

I've heard of people comfortably running 18psi through these.. There's more to the turbo than my graph shows imo

[GtstCoupe]

so compared to a gtrs we are thinking that it will spool faster but may not have as much top end as gtrs

[Primordial]

yeah thats the general idea i think..

My kit arrived today:

Will bolt it up after I purchase poncams and fuel system upgrades, so probably early next year.

[GtstCoupe]

I love it itl ooks hot.lol

carnt wait to see results on the dyno.

[Munna1]

Cant wait to see the results Mint keep us posted.

cheers

Did customs charge a tax on this?

If so how much if you dont mind me asking.

I asked this question ages ago. Do you guys recon the standard compression on a RB25 will handle 1.3 bar/ 19psi or would a thicker head gasket be needed.
