im low on cash right now, but i want to drive it the rest of the summer. need some ideas guys. i want an internally gated turbo that will bold up to my log manifold. (for an RB25). i would imagine a basic T3/T4 is what i need. where do i look? thanks in advance. haha.

Yeah. Is your intercooler full of compressor blade bits ? I shouldn't laugh, but this gives you the perfect excuse for a turbo upgrade. There are lots of T3 turbos out there that will fit with a spacer flange and longer exhaust manifold studs. You can get a GT3076 on there but you'll need injectors and a serious tune. There are some borg-warner turbos that have T3 inlets with fat compressor maps and internal gates.

Someone must have sabotaged you when you were chilling with your hood open That sucks though dude. Splurge a little. There is still alot of summer driving left. You don't want to use some small crappy turbo that you won't enjoy as much.

+1 for the gt30! you can get it internally gated and will bolt right to the log manni, only thing you will have to really fight is the down pipe which really isent that bad

I did a GT3076R this spring, and I love it. But... it wasn't quick. It takes a long time to figure out lines, fittings, spacers, downpipes, wastegate actuators, new hotpipe, bov flanges, etc. It took me a couple months of research and buying parts and stuff. Then... hopefully you have a PFC or a way to tune the car, plus injectors, and fuel pump to handle the extra fuel.

If you want to be back on the road asap, just get another stocker and slap it on in a few hours.

It depends how quickly you want to be driving again.

A more economical would a be your standard .63 a/r T3/TO4E 50 trim.Nice spool, plenty of power for now.

well, i was winding out 1st gear right by my house. POOF! a cloud of smoke from under the hood. after that point, it will NOT make boost at all. the car drives fine, just wont make boost. lol. oil pressure was fine and everything. i pulled it into the garage, and popped the hood. kinda dark, but everything looks fine. it had been blowing oil for the past week or so, so i kinda expected it. just not so soon.

like i said, car runs fine. just no boost. im running map sensor with my EMS. so tuning isnt an issue either. im just short on cash. haha. ill have to look into those turbos. oh, my injectors are stock, but i do have a walbro fuel pump.

that sounds just like what im looking for. except its not internally gated. the price is definately right, @ $620 though.

my plan was to go with a GT turbo this winter, but i guess things happen..

All t3 hotside turbos will fit, and all t3/t04 hybrid combinations will fit if the cold side is smaller than a t04e's. If you want to clear a t3/t04e, You'll need a spacer, and longer studs. I'd suggest that route, a t3/t04e is about 1/2 the cost of a GT series... Only problem is finding a internally gated one.

I bought the Garrett t3 super 60, its internally gated and just a little more power over the stock turbo... They claim 350 hp out of it, but I'm not so sure...

well guess what? i got off my *** and went outside. i blew the cold side off my FMIC. that would explain the car not boosting. and the oil...my catch can was full. i guess we all have to start somewhere. i couldnt see last night because it was so dark. and i had no idea the catch can would fill up so quickly.

but thanks for the responses guys. i still want to research this so i know what to do incase it really happens.

I could be wrong, but if you've been blowing oil for about a week could it be possible that the seals to your turbo could be starting to go anyway? I don't see how the catch can could account for you blowing oil... But then again, I am a noob when it comes to turbocharging... Glad to hear that it wasn't that serious of a problem!

would the turbo be to blame for filling up the catch can? I know that the catch can is connected to the valve cover and I don't know how the turbo could be causing more oil to vent through the valve covers...

you're right it shouldn't. if the turbo is blowing oil you'll fill the ic pipes and ic and consume the oil. not much to do with the catch can filling up. that's from blowby.

So in helping me understand this better, blowby and the venting of the valves sends oil back into the intake to be burned (on a factory setup) or into a catch can... How much oil should normally be sent through this process? Like lucky7 posted, his catch can filled up in 4.5 weeks. Is this a normal amount of blowby? Granted I don't know how large his catch can is, but that seems like a lot of oil. And if you did have an abnormal amount of blowby, what could cause it? I'm just trying to further my knowledge...

what are you saing?? my chit is gonna blow up??

yeah, i think its blowing more oil than it should. the odd part is, after i emtpied the catch can, i checked the oil. oil level is PERFECT. if its true, and im getting alot of blowby, my compression should be suffering. which is odd, since i put down 305hp and 315torque on the stock turbo. which IMO, is relatively high for being pretty stock. granted it was on a dynapack, so the numbers could be a bit inflated.
