Hi all-
I went to my local junkyard a couple months ago and pulled a series 2 3800SC from an '03 Regal. Now, a buddy of mine is constantly ragging on Fieros, and I want to shut him up for good- (and also, everyone loves lots of power in a small car) So I've set out on a mission to make 600HP from my engine. I found this article to use as a base for my build. Have any of you built an engine similar to this/have any tips and tricks?
so far:
Stattama Turbo cam #5
Duration @.050' is 230/224
Lift is .544"/536" with 1.6 Rockers
Lobe separation is 117 degrees - $519
Requires: 150# valve springs, modified retainers-? Comp Camps OER or LS7 Lifters, Rollmaster double timing chain, machine oil pump cover, PCM tuning
PAC Valve Springs- 150#- $219
ZZP 3800 Performance lifter trays- $189.99
ZZP Hydraulic Roller Lifters- 3800- $109.99
Rollmaster double timing chain- $135.99
ZZP performance 4340 H beamn 3800 connection rods- support 1000hp- $599
ARP 3800 Head studs- $99
Oil pump kit- $114
Z3 Turbokit- (still need intercooler) $2,439
Siemens Deka 60# Injectors- E85- $317[This message has been edited by Lewie (edited 09-19-2024).]

And the transmission will be what?
That's the hurdle with any engine swap. not the engine power.

I read the article but I'm confused by the "N/A" dyno of 267/247 when what's pictured is a SC motor.
I have a Series 3 N/A motor I've been meaning to rebuild as a replacement for my now dead 4.9...
I was looking for some basic upgrades for that but I seems hard to come by as everyone just goes the S/C or turbo route.
I've found this but it seems Series 2 oriented: https://zzperformance.com/b...aspirated-top-5-mods
I'd love to have a N/A 3800 that makes more hp than my 4.9 did while only giving up 50 ft*lbs at most.
For reference, my 4.9 made 196 rwhp and 298 ft*lbs on E85. I believe it could have made 5-10 more but my tuner tends to tune rich by my standards.
Best of luck on your build!

Siemens Deka 60# Injectors- E85- $317 - these seem overly small. In your linked example they used 1500 cc or 143 lb/hr injectors

The 3800 SC engine is quite strong in stock form and would swap cams and turbo it and use the $$$ saved on transmission work.
If I was an automatic guy and looking to build a stout 3800 Turbo, I would follow this thread:

A guy ragging on a 3800 Fiero? Point him to this video where Scott ran a 9.87 1/4 mile at 142mph with his 3800. That guy has nerves of steel.
Ultra Fast Fiero
If that is your target it will be a hard one to beat.

I run a 400HP+ 3800 turbo setup running through a 5-speed Getrag (Yes. Getrag. You heard right. It hasn't blown yet!)
I eat Porsches and hi-power BMWs for breakfast!
Never had a Skyline line up against me. Maybe they're scared?
Ask away, I'll try to answer.
One thing I'd suggest is to reinforce the front cross member of the cradle. I cracked mine.

This is what I'm going for- There is a guy in my hometown with an LS swapped Fiero, he has a 6 speed manual- I'm trying to track him down and figure out how he did it. Manual is a must. 600HP is the ultimate goal, but really anything other than the stock 75 would be great. More realistically, I want to hit 400- I'll dm you
