I haven't driven a Fiero over 20 mph since I was a freshman in college around 2002 (I had a Formula with a 3.4 - that took me a whole summer to put in lol). I drove this one around the block with the 3800sc, but it didn't run well at all - Justin had to pretty much redo the whole swap. If it does run a mid/high 10, it will be over a second faster than the fastest car I've ever owned, so I'm guessing I'll think its pretty quick.

Pros/Cons to the choice of the Pt6262?


I felt it was a good fit for a pump gas 11 second car. It gets really good reviews on the turbo buick forums, lfiero67's car seems to like it and it was recommended on another fiero forum. I couldn't find much on specs for it, but the reviews were so good I thought it was worth the risk.

You mean pump gas 10 second car .

6262 is an awesome all around turbo for a 3800. Quick spooling, affordable, and has made 700 rwhp in a turbo Buick. Generally regarded as a low 10 second turbo in 3500-3700lb Buick's, but most are low 11s and high 10s. Makes 400whp without even trying. If your looking to stay under 450 whp a 5858 is a good fit too.

How would the 6262 respond to an L67 (lower compression), any different besides more PSI?

Also, What is the size comparison between the 6262 and Justins Holset 351VE?

The Buick 3.8 is low compression as well. Spool will vary slightly due to different compression, but many things will effect that. L67 will take a bit more boost to make same power as mine, but has a stronger bottom end.

I think the holset is a 60mm cast compressor, and overall is larger and weighs alot more than the precision or any aftermarket piece.

I just sent you a PM. We've had two DW300's die in the 3800 turbo blazer on E85 in the past month or so. They sent out a new one right away each time. Can't blame this pump on the E85. Scott is going to call them tomorrow and see whats going on. The one in my car and the two in Scotts are all going strong but we got them early in production. I wonder if they recently went with a new manufacturer method or parts supplier.. This is disappointing.

False alarm! I'm always thinking the worst. A 10amp fuse went out. It looks more like it slowly got warm and failed. This pump might be too much for a 10amp fuse. They usually look burnt if they just blow.

Trailer with the blazer on it blew a wheel bearing half way to the track. Trying to get that fixed and hopefully get to the track before it closes.

Didn't get to the track to a little after 4. They close at 5. It was sunny and near 60*. I tech'd in and they didn't even look at it or anything. Jumped in the staging lanes and someone blew up down the track. Didn't get my first run until 4:30 and hot lapped it from there. We didn't get a chance to look at any of the scans or make any adjustments. Didn't have time to put the downpipe on either so all runs were with the muffler at 17psi. (It feels quite a bit faster with out the muffler).

First run I left easy. Didn't stall the converter and ran an 11.3@125.6.
2nd run I launched it on 7 psi and it felt like the fastest pass. For some reason the timing equipment didn't work right.
3rd run I tried 10+, it spun and got a little squirrely
4th run was the best of the day. I left at 7psi again and ran a 10.9@124.7
5th run I tried 10psi again. It spun very bad. I got out of it and then got back in it tried to chase down a G8.

It would have been nice to work on the burn outs and lower the tire pressure. I also feel like either the converter or muffler is holding it back on the big end. DH should be able to tell from the scans when he looks at them. He also took some videos from the outside. I'm uploading some from inside the car. I wish I would have put it on the side window though.

Converter looked a bit messy, but I didnt get a real good look at things because I didnt scan alot of the trans values. Timing was low as I set it up to be more of a boost car (taking advantage of the seemingly godlike intercooler) but he never turned up the boost. It probably has 3psi left in it as it sits, but its a guess.

Spun really bad from what i saw, and you couldnt go wide open at the line. I have a few videos.

You guys made building a 10 second car look a little bit too easy. It seems pretty stable too. Did you tape down the headlights, or did they just not pop up?

First run they pooped up, then I taped them down. I thought for sure it was going to be in the 12's at first. I was surprised to see the 11.3. Its just a Sunday drive out there. The car feels very comfortable.

I know it would be alot easier (aka the input shaft / chain wouldnt be not as pissed) if the boost was up more. I ran 19psi on that cam before with a crappier intercooler without issue on more timing. I tuned this fiero for 21 on paper but never tried it out.... It should handle it without issue and the efficiency island should be pretty close to perfect at that pressure ratio. The 60 fts seemed easy, it probably has 1.3s in it without issue on some tires if you wanted to grill the trans.

Converter and timing are deceiving. I would guess that timing would have added 2-3mph from my experience. Converter loss is still largely unknown, but on par with some of the things I talked with zzp about years ago.

I wonder if part of that is the compression differences between the l67 and l36. I'm sure the 3500 stall isn't helping the top end either.

good point, forgot about that as well... same/same for timing/boost, you effectively get to add on another 2psi when you are boosting a l36. \

Plauged with some mystery problems at the line and no time to turn the boost up, i was somewhat happy for what it was able to do on 14-15psi. Was sorta stupid that he bent the front control arms practicing 12psi launches on the street less than a week ago, and couldnt make 3psi today made rolling down on 4 9.5 inch slicks look pretty dumb.

The blazer has a tight converter and it's consistently 1.5mph faster at the 1/8th 1000' and 1/4 mile markers. It's not like the fiero fell off...compared to the blazer anyway, unless I'm missing something.

I run 16 degrees up to 5500 rpm, then ramp to 20 or 21 degrees at shift point. Timing would probably help alot as long as it doesn't ping, at all, otherwise you'll loose a head gasket right away. I'm running a 3250 stall, if your slip is worse than mine, it's definately hurting. Think I had 18% through the traps. Compression definately helps me, but you have more cam and a larger turbine housing, both of which the general masses believe will help your setup over mine. Can't wait to hear what you think when you get the car, I'm sure it will impress you to no end, turbo power is unbelievably different than the M90. Congrats on the car!

Which is why i setup the timing to just go nuts on boost because I know I can flow it easier than trying to get fancy with finding a timing edge on 93 octane. I also just left it off the top of the spark table via air temp, so its not hard to switch out if needed.

Thanks, The fastest fiero I've ever driven was a 3.4pr Formula (I bought this GT not running right specifically for this project). A Fiero this fast will be interesting.

I assumed the t4 would hurt it more than help over the t3. You have a very well thought out car, I used it as a guide when I was collecting parts.

Thanks

Now if I could just get the trans to last a summer and actually run it to the potential. Think I found a design defect with the 7/8" chain setups everyone is running that might explain why reluctor wheels shear rivets or bolts and come loose. I think my last chain failed due to a rivet going through the chain and gear. Going to talk to Dave at TEP and see what he thinks.
