okay so I have a 2nd gen turbo 2 Series 4. The mods I have are simple:

-exhaust (gonna make it a straight pipe)
-K&N filtercharger kit
-emissions/smog removed

okay now im gonna get a fuel cut defensor, remove cats and get straight pipe, 3 or 3.5 inch downpipe (not sure what size yet).

My questions is, Is this a good idea? what im worried about is boosting to high and killing my motor. Also i should be getting or rebuilding my injectors and maybe a fuel pump and filter. please help i wanna have my car setup right.

 

Port your wastegate before the exhaust mods, if not your gonna have alot of problems with boost creep and it can kill your motor!!!

 

or buy an EBC and your all set.

EBC = Electronic Boost Controller

 

Get an upgrade fuel pump.
Rewire the fuel pump for better voltage.

I dunno why you would want a 3.5" downpipe; the 3.0" downpipe is fine.

I wouldn't recommend any boost controller.
People get into too much trouble messing with those things.

You're already hurting your Wankel by spelling it wrong!

All the bolt ons in the world (other than a bigger turbo) won't put you above 12psi (with a properly ported wastegate)... At that point your next concern should be more fuel and a way to control it...

 

I pulled the exhaust off at the end of the DP on my 93 talon, and I get mad boost creep. It is maxing my 14psi stock boost guage out, before it was at about 11, it is prolly around 18 or so now. It is fast as ****, and spins really good, but I wouldnt suggest it with your rotary engine, they seem to break easier.

 

upgrade fuel pump
upgrade secondary injectors to 720
and fuel management (rteck chip, AFC, Standalone, ect)
port wastegate

Electronic boost controller will not controll boost creep

 

A boost controller cannot lower boost past what the wastegate would naturally achieve.

Meaning that if he is boosting to 10 PSI without the controller, his minimum boost with the controller would be 10 PSI.

 

how much would it cost to get my wastegate ported? or is it better if i get an aftermarket one? also im confused on whether or not i should get a boost controller. love the input guys and ya i fucked up i spelled wankel wrong

 

is it worth getting a fuel management system for the mods im gonna get? if ya whats a good low budget system cause i know haltech is the **** but its way over my budget.

 

You can only get an aftermarket wastegate if you are running a manifold (ie; turbo upgrade) that accepts an external wastegate... You can port the wastegate however (ideally 35mm), and there are many ways of modifying the flapper... To have someone do it would cost between $50 and a couple hundred bucks, unless you have a die grinder and a little free time...

 

rtech 1.7 is good for the mods you want its a remap of your stock ecu and it pretty cheap $125

without fuel management you can not run with the mods you want the car will run lean and blow up

 

ya this is what i was worried about. so what mods should i add before its not safe and should get a fuel management system.

rtek7 looks great im gonna get that as soon as i get the $$$

 

if you pull the turbo off and port the wastgate then you can get the 3" turbo back exhaust.
do you have a 3" TID with a pod k&n or just a k&n panel filter?.
Note. honestly. your gona have to pull the turbo of and port the wastgate before you do any mods to free up the restrictions other wise your gona blow your **** up.

 

once you free up the exh. the turbo will be able to boost higher so you need fuel so no exh. till injectors, fuel pump and rtech and portwastegate

airfilter sould be ok

save up and do it all at once the right way saves alot of headaches

 

ya thanks for the info. thats my plan now, time to save up $$$.

 

rtek 1.7, 720 injectors, fuel pump, bnr stage 2 turbo, exhaust and your good to go bud!

Plus that would only be about $1500- $1700 and probably get you as fast as youd like for now

At least thats the route Im taking and I hope to see mid to low 13's. With other mods of course, but that will be the main mods

 

okay so luckily i won an rtek ecu upgrade at sevenstock so know i just need the injectors, pump, exhaust/downpipe, and porting the wastegate. but how much is the bnr stage 2 turbo? and is it a direct replacement (can i keep all the other parts the same/stock: oil lines, wastegate, TID,etc.)

 

Why don't people read Aaron's Website

You need to read more and ask less questions.
If anything, why not ask BNR directly since it's their products you're asking about?
