vj14 to t25/t28 Questions

[mikemounlio]

I want a bit more then just 12 out of it. looks like a new turbo is needed for me.

[mikemounlio]

Turbo is ordered! Now i need to find some injectors in the 450-500 range, the manifold adapter to t25, get my ecu hooked up, get a cheap laptop to tune with, and get the tuner ready. Need to have this done in a month or less. I dont want to miss race number 2.



might as well add in my new honda radiator and do the front core support while i wait.

550cc rx7 high impedance is what you want.

Mike I don't recall but which ecu are you going to use?

How? The vj14 i just put on it was at 15 psi and it didnt last. I think i saw 18 on the last oone one time. Im still going away from the vj14 tho! Just want to get something now that i can still work with later on. I still plan to swap to a g series. Still gonna get a custom mani made. Still looking at a custom intake. Gonna make the car how i want it but stuff takes time. Lots of projects at the house besides just this car to worry about.

I have explained how several times. 2" exhaust, stock tune, stock diverter valve routing, stock intake and airbox. It cranks along with Z06 corvettes all day and has for around 100K through 2 owners. Quite a few people on here have ran stock B6t swaps for years and years with hardly any trouble.

Mike, To put things in perspective. I have a pile of ball bearing garrett turbos, I have b6d head flanges here at my shop and all the tubing necessary to build a header. When I put Tweak together with it's new engine (after trying to run a hybrid charger on a chipped ecu and blowing the engine and turbo up in 1 weekend) I chose to run a minty fresh bone stock setup. Why? It's reliable and fast. I have extensive experience building turbosystems, and extensive experience making cars fast. I know better than to fix something that isn't broken. The stock b6t/festiva combo is magical to drive. It's a rare balance.
I would fix the existing issues with your system before throwing a bigger turbo at it. Your blow off valve is most likely one of the major contributions to your failures, your exhaust is as well. With those issues, the management system is not properly controlling your fuel and your not getting the power or drivability that you could be getting.

Just my .02

I get all that but i want more power then that. 15-16 psi was ok but i could use more power. So the only way to get there is to ditch the vj. The turbo i got will get me going. As i upgrade i can reuse these parts on my other car if i dont go bp

It gets a lot more complicated than just slapping a bigger turbo on. Your better off starting from scratch. This road has been crossed by many before this and it gets involved. If you just properly fix this car and build another with this enthusiasm, you'll atleast have one to drive. I've seen this stuff turn a nice car into a never finished or driven again project wayyyyyy too many times. I just hope this doesn't go that direction. This is a nice car and FM10 is coming up.

Well I'm full on down the road already. Car will live again. I have the money to play with so it's not to big of a deal. I'm going to a bigger turbo and doing the mods to support it. I'm not going to throw it togeter.

It will be alive very soon.

I'm not replacing the manifold just yet due to time mostly and budget. I have other projects I like to spend on so I split up my spending cash as needed.

Cool..keep us posted with pics please as you are getting this stuff all together.

Is there a limit to how long a tube of a turbo header can be. I'm looking at 1.44" id schedule 10 and wondering if 3 foot runners are too much. It's difficult finding tubular turbo config info. Plenty of folks with na header maths
