DrivingTheDream Posted May 16, 2006 Share Posted May 16, 2006 Another BPU Q... I've ordered parts from Gaz at Envy and just asked him for a BPU set up. On the list: Blitz NUR Exhaust Full Decat inc. Ring FCD Not on the list was a fuel pump-Should it have been on? Quote Link to comment Share on other sites More sharing options...
jamesmark Posted May 16, 2006 Share Posted May 16, 2006 I use a boost controller anyway because I use a 1 bar restrictor. Are you saying your exhaust has replaced the second cat? Unusual. not up on the exhaust things but i bought a cat back kakimoto exhaust that i think with go all the way up to the first cat, but the exhaust its self has a cat built in, so will always have one cat there, but want to remove the cat coming from the manifold and only rely on the cat back, am i on the right lines or is a cat back more restrictive? or will haveing that be ok and getting rid of the other cat Quote Link to comment Share on other sites More sharing options...

Diagrams here of the different models, I can't remember them including a cat (could be wrong), are you sure it is a cat and not a second silencer box? http://www.kakimotoracing.co.jp/01-01-01_t1.html#JZA80 A cat back exhaust means that you get complete exhaust, from the 2nd cat back to the tail pipe. Most exhausts are cat back and then the 2 cats are replaced with 1 or 2 separate straight through decat pipes. Saying that my ARC exhaust is a complete system from manifold to tail pipe, so there are exceptions. Quote Link to comment Share on other sites More sharing options...
Nic Posted May 16, 2006 Share Posted May 16, 2006 Really? I've never heard that before. It's been that long since my VVTi was on the road I can't remember if I've tried it decatted and without a restrictor With you there Jake, I've not heard that before either. So do the VVTi ceramic turbos have a bigger wastegate? The VVTi turbos have a different part number, but I thought they were essentially the same as the earlier models.

TBH nic i only had a quick look at it last night as it was pissing it down with rain, but if it helps its the one from this thread as i have finally got it lol, i know the pic is not clear but i dunno you might know but it does look like this one but i cant remember if it had ther middle piece in it http://www.kakimotoracing.co.jp/image/gif/Regu06&R/T21345.gif but it did have the thicker part like in this pic (not the box in the middle) http://www.kakimotoracing.co.jp/image/gif/KR_image/TS345.gif i will take a picture of it tonight, ta nic Quote Link to comment Share on other sites More sharing options...

Ring FCD Not on the list was a fuel pump-Should it have been on? No. But it's a prudent addition. To me, for less than £100 it's not worth risking whether the elderly stock pump can flow enough to keep the mixture rich enough under (the now increased by BPU) boost.

Kranz Posted May 16, 2006 Share Posted May 16, 2006 BPU = Big Penile Upgrade??? And why would you want a ring restrictor, or cat:taped:? Here tiddles....... Quote Link to comment Share on other sites More sharing options...

CardiffSupra Posted May 16, 2006 Share Posted May 16, 2006 Quick question, Why do you have to upgrade the exhaust go to bpu? Can't you just decat the standard exhaust? Will an after mark zorst give me more power? Cheers. Quote Link to comment Share on other sites More sharing options...

jamesmark Posted May 16, 2006 Share Posted May 16, 2006 Err that's a Kakimoto!

Homer Posted May 16, 2006 Share Posted May 16, 2006 Quick question, Why do you have to upgrade the exhaust go to bpu? Can't you just decat the standard exhaust? Will an after mark zorst give me more power? Cheers. The stock cat-back exhuast is very restrictive so will stop it reaching the higher levels (1.2 bar). Even putting the baffle in my RSR reduces boost by 0.1 bar. Quote Link to comment Share on other sites More sharing options...
Homer Posted May 16, 2006 Share Posted May 16, 2006 i know its a kakimoto but got some pics from nic and none of them tie up so i have posted pics as it seems that there is no second cat Was this the one that used to on Rays car? If so, its just a cat back, the 1st silencer is not a cat, just a small straight-through silencer, like the one on the NUR spec. Quote Link to comment Share on other sites More sharing options...

Bobbeh Posted May 16, 2006 Share Posted May 16, 2006 I believe so, and I thought they tried to claim copyright and stop other traders using it. Yup, Mark Tozer I believe. Well he tried to profit from the term. Quote Link to comment Share on other sites More sharing options...

It looks just like a cat-back, its to short to replace the 2nd cat pipe. I'm sure they made them as (IIRC) Paul Whiffin was selling them a while back. Maybe PM Ray to ask about it?

I think you misunderstood what I wrote Mark, I couldn't remember a Kakimoto exhaust that include a CAT. Agree with Homer it is a cat back exhaust and the first box is a silencer.
