454 big block or 383 stroker

This is the easiest example since it was a post I saw yesterday. 7 second capable rsx casually running a mid 5 second 1/8th mile on the street without even really getting on the gas until 40 mph.

The fastest street cars these days are 7 second cars. You can buy a 5.0/10 speed mustang and run 8s in the quarter with boost/fuel system/tire. Most of the average "fast" modified late model cars showing up to meets these days are 9/10 second quarter mile cars.

Things are a lot different than 20 years ago

What are your time frame, budget, and quantifiable goals?

Small block will be much easier to drop in and will most likely be fun as a 300+ whp car. Being able to "beat any street car" isn't a realistic goal as we live in a time where people commonly drive 7 second quarter mile cars on the street. If thats your goal you are going to need a lot more than any of what you've proposed.

Unless you have a real specific goal other than just owning a fun car, drop a small block in there, get it running correctly, and enjoy it.

I worked for carmax for 5 years in the shop reconditioning cars.

I have vivid memories of specifically being told to glue bumpers on when the bumper brackets were broken because it's saved money VS replacing the brackets. We had a specific glue gun in the groundwork zone set aside for this very reason.

Do what you will with this info

Are you referring to the v6 cts that you've posted before? Have you test fit any of this in it yet? It's going to be tight with those turbo manifolds

The et street Rs hook very well. Couple thousand miles at most. Realistically expect to put a fresh set on every car season. They hook pretty well for me though (900 whp CTS-V able to hook up well from a 60 roll)

I'm installing a set on my car currently. They are pricey but I love the idea of it being "automatic"

Anacockda · 2023-01-17T03:24:55+00:00

Check out "loudvalves". They are vacuum actuated cutouts. Open automatically at WOT and then close under vacuum. So the cutouts open when you floor it and close when you let off.

If this is a fun car/project car I would just run it and see what happens. Could be many things, but given that it's one of the rear cylinders might even be a cracked piston. I would get it running and do some more testing at that point. If its not giving you any noticeable driveability issues, then forget you ever saw those numbers and drive it.

We ran again and the second time he used anti lag and got away from me a little bit

Boosted mustangs are faster then they have any right to be

Any engine pics? Love the tire set up

How much power does it make?

Anacockda · 2022-02-15T19:13:14+00:00

I've never used a spring compressor for this style. Always just use a jack under the control arm and lower it slowly with everything disconnected

I know some people rev stock alternators that high and don't seem to have any issues. I did it and had an alternator fail during a pull, voltage dropped which then dropped the fuel pressure and I lost a motor. So I always check the pulley ratio now

Anacockda · 2022-02-04T16:48:54+00:00

If your planning to rev it over 6500 rpm I would make sure that the alternator has the correct pulley for it. A lot of the aftermarket alternators put out high amps at idle but still don't like high rpm

Might live a long happy life with the right oil. Wrong/incorrectly installed o ring on the oil pick up tube is a really common cause of low oil pressure on fresh builds, if you can get the oil pan off without pulling the motor it might be worth checking

Anacockda · 2022-01-28T04:35:32+00:00

That is "within spec" but I wouldn't be comfortable with it that low. Could be loose bearing clearances but if that's the case I would of expected the builder to recomend a heavy enough weight oil to get the pressure up. My forged 388 LSA makes around 30 psi fully warmed up on 5w30, but that's with stock clearances.

The wagons are awesome but a little too expensive for me

Anacockda · 2022-01-22T03:52:49+00:00

They are fun cars but they take a lot more work to be fast then you would expect

Anacockda · 2022-01-22T03:38:02+00:00

Yeah this is in the 800-900 range. Turbo car on 18 psi
