turbo on 3100

[Rootie524]

where can i find turbo headers for a 3100/3400 sfi engine? can anyone on here custom fab them?

im looking to turbo my malibu. but i have a concern. every turboed 3400 i have seen is only running 6psi of boost..thats weak! granted they were on stock internals..

so..i plan on getting a turbo cam, forged pistons with stock compression or 10.5:1 if its not too much, and the better piston rings to withstand boost, ported heads, i already have the stronger valve springs, ill get the manley race valves, and 65mm TB, and 35lb+ injectors..will probably get on the upward side of 60lb injectors cuz im going for high boost/high power.

so with a fully upgraded internal engine running a turbo..how much boost you think i could safely put on the 3400 engine and what numbers should i expect to see if say its around 200whp NA?

dude PSI mean nothing. You can have 6 psi and make more power then a car on say, 15. its the efficiency of your engine that will make you have power. you have to read on Turbo before asking question like those. And besides you don't have the car for high power.Before even starting with the engine you need bigger brakes better suspension and a Better Tranny. Right now your only doing a receipe for disaster.

well im trying to learn and find out a few things before i go and start beefing up other crap. on every car ive ever seen on a dyno..they have a built engine and for every 5-10 psi they add the hp goes up like 100..sure the efficiency matters. but what im saying is if i have a built 3400 i can run more boost and perform much better than a stock 3400 that can only go up to 6psi without risking blowing something.

60 lb/hr injectors?

totally unnecessary.

[Rootie524]

necessary if im running 300psi of boost!!!!

you'll also need pistons, rods, a crank, heads, cylinder walls, rings and finally headgaskets made of materials 5 times stronger than anything man has yet made...

but honestly, unless you're revving beyond the 7K the rods and crank can handle and running considerable amounts of pressure into a 3400(say 15+PSI), you would likely never need to go above maybe 36 lb/hr...

even then, you're likely to run out of room on the MAF...

I work at a shop in 19055 pa that does this work. Well it's Me that does the work but My boss will do anything that he can make a few $$ on and you get a solid job in the end.

levittown? im in the allentown area. so its not incredibly far away but not too close either. i'd be interested to see if you would be able to fab up some turbo headers and how much something like that would cost. u think u could get me an estimate? thanks

there is a company that makes them for the GA GT iirc.. look for turbo 3100 or turbo 3400 on google... you will find it.

Go to the library. Pick up Corky Bells book Maximum Boost. That will get you started in the right direction to understand what it takes to turbo a car. You need to know what you are doing before you pick up a wrench. Otherwise things (mainly your car, or innocent bi-standards in the worst case scenario) can get screwed up fast

Their have been plenty of people running upwards of 10psi on a completly stock 3400. And FYI it doesn't take much boost on a 3400 to give you more power than you can handle.

Your not going to get much of an answer to that question their isn't a set hp number you can make. The possiblilities are basicly endless.

not to mention the transmission...

Well, I have read about some 4t60e taking up to 320 ft/lbs of torque safely. Especially with a good ATF cooler.

Having forged pistons your internals are somewhat strong. I can't say how much HP you can push safely but I can say you could easily see 10psi+. Probably 15-16psi max but that will destroy your tranny if it is a 4T60e.

I turbocharged my 3100 and been punishing it for about 9-10 months daily (except for the recent downtime installing the KB Pistons). I keep the calculated torque to a max of 320 ft/lbs due to the trans. and installed a nice ATF cooler with temp gauge. Most trans failures are heat related so a good cooler will help out A LOT! I have a B&M Cooler rated at @14k BTU with bypass for cold ATF.

At 10psi 36lb injectors held fine and the MAF almost maxed out, but didn't. Traction at WOT 10psi is tricky for the FWD, and one wheel spin outs will destroy the trans fast. So I keep it at 6.5psi for daily driving. Anything higher and traction goes quick in the lower speeds.

I used a T3/T04E .50/.63 and it has very little spool time. Boost begins at 2800rpm and is at full 6.5psi at 3200-3400rpm.

10psi on these 3x00 FWD is enough for a daily beater. Anything higher is for serious track times.

Just my opinion

[robertisaar]

Anything higher is for serious track times.

speaking of which, don't suppose you ever got any solid ET numbers at various boost levels?
