Am I the first Chinese kid in this forum? Anyway I just entered this amazing world of Fieros as I got my first car as an 87 GT, It was pretty beaten but I managed to make it cool. I haven't work on any cars before as I just came from China and the labor back there is DIRT CHEAP. U can get everything taken care of for like 100 bucks for a car. So I got here, realized that shops want 150/hr for labor and a exhaust manifold gasket takes 8 hours, decided to work stuff on my own. I gotta say Fieros are bad bad choice to learn how to work on cars as its unique design. And after 8 months of working on and off, It finally runs smooth but I created TONS of new problem as I am such an idiot with 0 experiences. Broke all the clips trying to take off the plastic pieces holding the headliner, broke the door trying to install new window seals, fried wires when trying to put new speakers so now only the right rear speaker actually works and fuses popping like a party. But what's important is i fell in love with this car and after ruined mine, I found this forum. So I got this deal on craigslist about an 88 T-top with blowed engine. I bought it and trying to do something even more insane. So I have a plan swapping a 3800 in the Fiero and put twin turbos on it. The engine I got is a L26 from 07 Grand Prix, the concern I have right now is do I have to order new crank shafts, piston heads, connecting rods and all kinds of stuff for the extra boost coming from twin turbos and where can I get them. Those turbos I got are Precision 6262 rated as over 700 horsepower. It's definitely too big for 3800s but I got this cheap deal on craigslist and just couldn't let it go XD. What do u guys think I should do?
i know the 3900 has been done TT, and im sure *someone* has done it to the 3800, but the reason most go single turbo is the limited room, look between the firewall and the engine, where ya gona put that thing? youre looking at alot more fab work and trying to find a way to fit everything with twins, when you can get the same performance out of a properly sized single turbo... got 3800 turbo guys running in the 10's (other supporting mods ofcourse) and depending what you wana do, and how deep your pockets are, i wouldnt count that turbo out :P
I don't know if we had a Chinese kid before. I hosted a 16 yo from Guangzhou and a 14 yo from that other Chinese country Hong Kong this last school year. The 14 yo is coming back this next school year.
I really don't understand the economics of China when somethings are extremely expensive (housing in the big city) and when somethings are extremely inexpensive.

How much boost do you expect out of the turbos?
Those turbos are qualified for 14 PSI each but I have no idea about how to set it up. Just got this idea, doing step by step and see how far I can go
If you want twin turbos bear in mind that Forum member Darkhorizon has run a 10 second 1/4 mile with a single turbo. I guess a twin turbo 3800 has been done before but the age old question comes up; how fast do you want to go?

Don't use the L26 as they are NOT up to the task. Use a L32, L67, or L36. Also, sell one of the 6262 and use the other one. Search this Forum for and Grand prix forums for more info on a Turbo 3800. You can get a 10 sec car relatively easy with properly sized turbo and the supporting mods. The main problem with two turbos in a Fiero is space. Where are you going to put all those pipes.

I did some search about 3800 engines and did not find the reason l26s doesn't hold horsepower(lame). Stupid as me I just thought it will be easier if I have an intake manifold to turbo it :P Can u explain a bit about why l26s cannot hold the power? And since I already had the engine, is rebuilding it going to help? Thank u!

I thought some Firebird and/or Grand National guys had built twin turbo 3800's.
firebird had alot more room in the engine bays if your talking the 95 or newer ones... if your mean the odler ones, the 3.8 from the GN was a different beast.
Welcome. a 3.8 GN was a whole different engine. (Looked into it a long time ago). The reason to use a L67 Supercharged engine as a stating point is ,they Already HAVE a" Forged" Crank, Rods, & Pistons. If you have to first go buy these parts, it's going to get Real expensive Immediately .
The 6262 should easily make 700 hp on race gas or E85.
L26 is a bad start as you can see in a link posted above. It gave out at around 500whp. There have been other blow up L26's in grand prix's from too much power. Always rod failures. It wouldn't stand a chance with the power i'm making now. Pick up an L32 or L67 and resell the L26.
Most importantly, horsepower is the easy part. Getting a transmission to hold up will be the biggest challenge.

I already got a whole set of piston heads and connecting rods from another guy who sold his car. They're for Series II SC, I'm kind of an OCD and Im gonna rebuild my motor anyway :P The worry I have is the compression ratio, Is is because different camshaft and longer rods that the CR is different with the same block?
I asked the same questions ages ago (on a different forum), and was told just go single, ,I'm glad I did. it's enough of a headache to do a single turbo build, but a twin build... I'd be bald...

I'm actually thinking about single turbo right now. As other members said, there is simply not enough space to do that.
