Hey everybody

I have an hybrid turbo with the housing being different with a 3in inlet aswell.

had it rebuild by rotary power with 3mm apex and streetport.
as well as lightend fly
new silc. vac hoses

my boost is really low. 3# usally but 5.5 @ best.
i think i need a boost controller but want to go with Manual boost controller.
i know what type to go with. but went to double and may be triple check how it connect into system.

1. Do you place it inline or just vent the valve to the engine bay?

2. If so inline where does it go to?

 

I have a RB 3" downpipe too and a broken main CAT
and Mariah Cold Air boX
and KN 88 Perform AIr filter
and Greddy BOV
stock intercooler

 

Sounds like you should be ripping pretty good even at that. I've hear good things about hybrids. What are the specs or the stage# of your new compressor?

You must have the line running right to the actuator now. You're just on the spring. As far as connecting a MBC, easy, manifold vac/pres source to the IN side and the OUT side to the wastegate actuator. Set it all the way out or open to start, then ramp it up to whatever boost you want.

With an S5, you might have to do something with the stock solenoid. In fact, with that, get two mbcs and rig up a two-stage system.

Get a Ball & Spring boost controller. This is what I run and I like it. (in case you haven't seen the other thread)

 

all stock fueling ?????

 

nope
Walbro fuel pump is installed too.
stock injectors

 

We need some mor info, details on the hybrid would be help full, S4, or S5 exhuast side.

It would be VERY advisable to get some bigger injectors ASAP.

 

89 S5
steel oil cooler lines
it is just like the stage 2 @ bnrsupercars.com
i don't know what compressor i have got . i have asked but they did not give it to me.
had injector professionally cleaned.
have auto boost guage that works well was getting 8.5- 9 pound on old stock turbo.
have racing beat fuel cut controller
also autometer Air Fuel Meter and it always says i am running rich.
also a new O2 sensor Bosch.

 

has anybody got soem more info

 

depends if you get a bleed type MBC or a ball and spring one.

ball and spring is better. and goes inline between the turbo and wastegate.

 

i have a few brand new halmen boost controllers they are ball and spring type and only cost $45.00. they work really well. I have run these on 4 or 5 different cars and thew work great. if intrested i will ship them for 5 dollars anywhere in the us. e mail me at turbo2_rx7@yahoo.com
