JPT? and it holds together? Congratulations! You are one of the lucky few...
Really think that 125 can handle 10's?

the turbo build comes on slow like the 60' is 2.0 sec. so tires don't spin not like aV8 that hits the tires hard. I'v added a bigger 2nd servo and a longer pin and so far still working 5000 miles on it. Tell me what has happen to them that has cuse them to fail?

Hey John, I am glad you solved your posting issues, this is a pretty good site and it will keep you motivated to finish your Fiero. I know you are knocking at the doors for 9 sec time slip with your GN powered 240Z, but I hope you go ahead and complete the Fiero.
As you go along, you will see that there are few people on this site thinks that they know everything because they read about it or they heard from somebody but no hand on experience with the actual product. Just ignore them and go about your business like I do.
Nevertheless, Welcome aboard, I like to see you climb the ¼ mile list chart.

I haven't personally had one fail, but there are multiple people on this forum who have. I'd really like to know what fails, but no one who's gotten a dud has autopsied it yet...
If you know a lot about beefing up a 125, I'd really like to discuss it with you. I have an AWD Pontiac 6000 with a 125 transmission and I'd like to build it for a turbo 3800 S2. The weak link is obviously the trans, but hardly anyone knows anything about the 125's...

Nice work man, its so funny to me after reading all the info on this forum how the people on here debate and worry about every little detail and fraction of a second, then new people like you just pop up and say, "Hey check out my 12 second car" or "Guess what guys I have the '86 GTP prototype that no one even knows about" Haha!! Glad to see that people who actually have fast cars do take time to post once in a while. On a side note, does your original post say you still have factory rear brake pads after 100,000 miles? Thats awesome!!!

The front wheel drive block that I'm talking about is the 3.8 buick that's in the 1986,87,88 cars buick centry, lesaber,park avenew,pont. bonivill,olds 88,98. The 8th engine code is ''3'' with a factory roller cam or ''B'' that had flat tapit cam ''B'' was in 86 and part of 87. ''3'' 87,88. In 88 ''3'' I'v only seen in Buick centery. You can biuld a cheep turbo engine with this block by just replacing the pistons with the 89 turbo TA turbo 8 to 1 pistons and port the heads wich are the same heads that are on the 89 turbo TA. 350 HP is not that hard to do and it bolts up to the stock 125 trans 4t60 4t60e and so on.

Hey John, have you ever been to the Buick Nationals in Bowling Green, KY? I seem to remember talking to someone there a couple of years ago that had a GN powerplant in a Nissan that was very fast, just wondering if that was you. Nice cars, although I have to ask if you can get some more pics up of the engine bay.

cool car! does this engine have the non split throw crank? is that why you used it?
My understanding is the the crank is very similar to the Turbo crank in the buick GNs, they both have rolled fillets, both on the mains and rods.The only main difference is that the fly wheel bolt pattern. I am pretty sure John will chime in here and correct me if I am wrong.If that is is as strong as the GN crank, we have guys making close to 700+ fly wheel HP in a stock block with billet caps like John has in his Fiero.
Hey John are those GN1s the early casting? are they ported? how about the intake? is that one piece or too piece like the GNs?
Thanks Prasad

Your right the crank is allmost the same and has one more good thing a one piece rear main seal and a slot for the oil pump drive. The intake is one piece so I can't put a power plate in it. I think the series II engine is much stronger becuse thay came with steal main caps that are cross bolted to the botom of the block. I took 3 of the main caps from a series II and put them in my engine and line honed it becuse they where free. yes they are the early ones and are not ported it has enuff flow now. With 22# of boost and a good intercooler I will have more than enuff flow for the 10's.

can i get some pictures of the turbo manifolds and piping? this seems like quite the way to go if you want to build a turbo 3.8.
are those aluminum heads?

it was roumored that the cranks that did not have the split throw were stronger. they split the rod journals to even out the idle (and added the balance shaft) what geezer would give a care about a rough idle!
they used different rods and cams

Yes they are aluminum heads I think it was 78 was the last year of the none split throw cranks. It ran like a V8 with 2 missing cylinders. The balance shaft was stared in 88 with the series 1 engine the 3300 never had one.
