Turbo Y4

**FastFwd** · 04-06-2009 09:30 AM

When i originally turbo'd my b16a2 i was going to use the Apexi Vafc 2 i already had installed to tune it. I brought it to hyper drive in perth and they tried to tune it and said "it will work but i wouldnt trust it" they also said that you couldnt push more than 6psi with the stock injectors on a piggy back ecu setup.

They can only go so far, Piggy back ecu's are great for mild NA setups as they are pretty much as far as they can tune but when you get boost or heavier applications the piggy back cant go any further. So your robbing yourself of some power going with the piggy back plus its extremely unsafe.

The harsh truth is allot of people still wont use the Piggy back setup even if you do get it working. Because people know what they are and arnt capable of and they defiantly arnt capable of holding a safe boosted tune.

And trust me on this, you really dont wanna be rebuilding your engine. Im on my third rebuild, so take my advise and play safe. Save some more money and get a ECU that will do the job and more.

just an update guys. since im trying to keep this to a lowish budget, & because im running relatively low boost, im looking at getting a 3" press bent exhaust. because i plan to keep a stockish appearance, im looking for a stealth muffler similar to the vibrant street power muffler pictured below.

i chose to go with a 3" press bent exhaust, once the bends are pressed, the diameter should come down to around 2.5" & should be alot cheaper too. maybe later on ill upgrade to mandrel bends, but for now this should be fine.

Does anyone know if there are any vibrant distributors in australia?

Here's why, because i was originally going with a 2.5" mandrel bent system, since we live in australia where prices for everything are through the roof. wouldnt a 3" press bent be very similar to a 2.5" mandrel bent, because the bends on the 3" when pressed will come down to about 2.5". I know mandrels have superior flow characteristics, so im sure a press bent system will be just fine, im not after big HP after all...

i may not even worry about mandrels if i get the 3" zorst. i may upgrade later, i may not...

press bent disturbs the flow of any sized exhaust.

should go 2.5 mild steel mandrel, i did and i got mine for $300

I did my 2.5" mandrel for round the $500 mark

Found a S pipe off a DC2 2.5" mandrel second hand, like $90

Chopped here and there and BAM good to go!!

3" press bent will be fine!!! there is only a few bends in a civic exhasust anyway so i wouldnt worry really its not like your aiming for 600hp.... you will see no performance difference between 2.5 mandrel and 3" press bent as for the muffler make sure to get a 3" inlet and outlet box and paint it yourself with some high temp engine paint wont come off and looks good and really cheap to do

in an N/A car press bend is fine as there is less flow. In a FI car press bend will cause turbulance and backpressure. I would recommend getting the mandrel bends.

On stockish mufflers i'd get a magnaflow, cheaper than your vibrants and i'd say just as good if not better

I got 3 inch mandrel bent in stainless for $1200

Just get any type of muffler, even a clean cannon type and just paint it with high temp black paint.
