You won't be in boost on the highway at 3000rpm. The throttle will not be open enough to build boost while cruising. You'll actually be getting better gas mileage because the spent exhaust gases will be spinning the turbo and sending more air into your engine with less effort from the engine.

 

So even if I'm cruising at 3000, or even 4000 rpms, the car won't be adding more fuel for boost? That makes it easier then and I can just weld the internal gate arm closed. Thanks

 

If you're just cruising, you should be in closed loop mapping meaning the car will simply be trying to achieve lamba (I believe). If I trust lightly press on the gas pedal, I can go right up to redline without hitting boost. The reason is because the car isn't under enough load.

 

Exactly what amby said. It's rare that I'm in boost while I'm driving. I keeps tabs on my boost gauge and put the engine under enough load to not cross from vacuum into boost. And the pull from the turbo is still there under acceleration and more fuel is being used, but not as much as when you are boosting.

 

so what point have you gotten to by now?

 

I've put it on hold because of money. The place I went to get a quote on a custom manifold told me to expect around $1000-$1200 so I told them they were ridiculous. As long as my 14b will bolt up to the RRM turbo manifold for the 16g I will prolly just get that for $400.

 

I paid $1000 for my ram horn, downpipe and wastegate dump tube. Before I found this fab guy I also got quotes around $1000-1200 for a ram horn manifold. Shop around and talk to car guys and see if they know anyone that makes manifolds on the side or in their garage. Or find out shops that have just recently opened and don't have to inflate their prices because they are trying to establish a loyal customer base.

 

I got my manifold from rrm for $400.

 

Yeah, I didn't even want a ram horn style because I knew it'd be expensive. I'll just get RRMs cause I don't have time to drive to Houston. At least I know RRMs will fit right.

 

yeah and you get all that support from RRM if things go wrong

 

exactly. So on my next paycheck or so I'll get that. I'm buying a tial WG from a member here. Prolly a fuel pump from a member here. Then I'll be ready to set it all up to have piping made.

 

sounds like a plan. I used some evo piping for my setup.

 

Hey I just bought a 14b turbo today and it looks like we are both going to have the same setup...
So far I just have the 14b and Evo VIII fmic. Can you make a list for me on what else I would need to finish my setup? Especially the manifold and the whole wastegate thing.

 

cant go wrong with a rrm kit.

 

Do you want parts in general, or specifics? Like just a turbo manifold, or RRM manifold? Here's a general parts list that I plan on starting off with:
14b Turbo
Oil Feed and Return Lines
Tap Oil Pan for Return
Water Feed and Return Lines and Banjo Fittings
RRM Turbo Manifold
Tial 38mm Wastegate (lowest spring I can get)
Intercooler
2 Slim Fans (as big as you can fit without getting in the way)
DSM Blowoff Valve
Walbro 255lph Fuel Pump
Vortech 12:1 FMU
02-03 Lancer Intake Manifold
02-03 Lancer Fuel Rail w/ Return Line
02-03 Lancer Fuel Pump Assembly (or just add a nozzle on the 04+ assembly for a return)
Spark Plugs (can't remember the NGK number that was recommended, but I'll look that up)
Custom Piping from Turbo to Intercooler, Intercooler to Throttle Body, Turbo to exhaust, and Wastegate to exhaust

I think that's everything. I also plan on buying an RRM turbo piggyback since my setup (aside from the turbo) will be pretty identical to their setup. Then from there I can tune on my own or at a shop and upgrade parts as I get more money.
