Turbo ecu

[Cavalier9696]

Anyway I can get away with the stock WG right now? Running low on cash..hehe Dav did the check out my turbo pics to see what the bolt holes are for? Not sure if u saw link. This site was acting crazy for about 10 minutes, kept freezing on posts.

Ya AF must be doing some updates. I can't even delete the double posts or anything right now.

That turbo is water/oil cooled. I see the oil feed line is still hooked up, so the others are for water. You don't have to run the lines, especially at such low boost, but find a bolt to plug them up.

So as long as I run my Oil return drain line IM ok? Bought this. http://cgi.ebay.com/ebaymotors/ws/eB...=STRK:MEWNX:IT The manifold I got coming uses 35/38mm WG. So hopefully the stock will last till I get a external.

I wouldn't run more than 6psi or so no the FMU setup. That really is a terrible fuel system to run on the car. If you want to run more boost I would recommend upgrading to a SFMU and putting in those 450 injectors, the SFMU will allow you to lower static fuel pressure and lower the rise rate of the fuel pressure so you wont be so high. I dont remember the exact graph of the walbro 255 pump but above 80psi it doesn't flow as much fuel. The FMU may work for a little while but I woulnt plan on running it forever.

I also agree with Dave ab using an external WG. To use an internal you will have to add a spring to it to lower the pressure down some, I tried to run this method a few years ago and never had much luck. Boost pressure was never consistent.

I know it may end up costing you more money but your setup will be much safer and you shouldn't end up with a blown motor in a few months.

Agreed. The oil return line (also has the feed in there too) is fine. I replaced all the fittings from mine but I needed to for other reasons. They hold fine as is though.

I really never had too much problems with the FMU and the pump. Only time I would run out of fuel was when the boost controller wasn't working properly and boost was spiking.

What year is the car?

[Cavalier9696]

Its a 95 rs. Just was hoping I could use the Internal WG for now and just run at 5psi. Not looking to get any serious speed till I get better internals.

[SilvrEclipse]

Used wastegates can be found for under 100. That is the route I would go. Also mine came with a 5psi spring in the kit. Would be perfect for your setup. Don't buy a cheap ebay wg if you decide to run external

Ok, I asked on the year to see if you would need a Missing Link or a FCD, but you'll be fine.

So the setup I have right now will be ok till I upgrade?
Thanx alot for all the help guys. It was really needed. Ill keep ya updated just incase I need alittle more help. Hopefully will start in a month or so.

[david-b]

Ya I believe you got everything. Seems to be good from what I've read.

[Cavalier9696]

Oh ya 1 more thing. When putting the intercooler on, do I have to take the stock 1 out? Or would it be fine to just leave it in? Or do people take it out basicly for weight reduction?

[david-b]

NT don't have intercoolers

[SilvrEclipse]

Yea you either talking about the radiator or AC condenser

[Cavalier9696]

lol ya it was the condenser. I can't get over how small the fuel pumps are. Fits in the palm of my hand...lol my girl said it was cute. Cause the cavalier fuel pump I put on her car was ALOT bigger.

Hey I forgot to tell you when order that flange adapter, make sure you order the gaskets as well. Will need 1 Mitshubishi turbo flange gasket and 1 T3 turbo flange gasket.
