Hey Guys,

I have just bought my R33 RB25DET about 3 weeks ago and I want to put a front mount on there. I found a nice one that i want to put on there but i am not sure about the size becuase i heard too much air flow will cause my turbo to lag / take longer to spool.

My question is do you think it will be ok as the Core size is 4'' and the outlets are 4''. My car is stock, only mods are B.O.V, HKS air filter and 4.5'' catback exhaust.

Any help i can get on this topic will be much apperciated!!

Thanks guys! :blink:

Why do you want 4" outlets? 3" is more than enough most kits come with 2.5" or 3.0".

Or shouldn't I be asking when you've got a 4.5" exhaust? :blink:

4" is overkill unless you've got a massive turbo. Its not about airflow that causes lag, what causes lag is the time it takes for your turbo to build pressure in your piping to your intercooler and plenum and the intercooler itself, so the bigger your piping, the more air your turbo needs to flow to build up that pressure.

Well basically i asked my cousin what brands are good for intercoolers and he said he has a brand new hybrid one he can sell me for cost price but its got 4'' core and 4'' piping which is too big obviously... lol

That would have been perfect though coz the price was good and the intercooler is pretty big... hehe

Thanks for your answer mate!

If you're going to mod your car a fair amount then go for it.

If you're only going to mod it mildly, then I would go for smaller piping and core.

But hey if the price is right then take it, you may not even notice the extra lag over a smaller core, I'm just saying a core and outlets that big really isn't necessary.

I'd be surprised if you had a 4.5" exhaust [as per prophetR33's comment, he was hinting that as well]. I would believe it if you had a 4.5" exhaust tip, but your exhaust piping would be more like 3".

And yes 3"is heaps unless your pumping out huge rwkw's with massive high end power aka drag racing.

    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
