Castro Motorsport: The Purple ///Monster

[e30polak]

My M3's amazing new exhaust custom built by Chris Castro of Castro Motorsport. Chris made a custom collector for the header for the front 3 cylinders to clear the front subframe. Downpipes were custom made to clear the front sway bar and the control arm lollipops.

Specs on the exhaust fully built by Castro Motorsport:

Modified eBay headers > dual 2.5" stainless steel mandrel bent down pipes > V-Band clamps > dual 2.5" SS piping continued > X-Pipe > dual 2.5" SS piping continued > Flo Pro 22" stainless steel, straight through muffler > V-band clamps > dual 2.5" SS piping continued > Active Autowerke Generation 3 e36 m3 muffler > dual 4" double walled, angle cut polished stainless steel tips

***DISCLAIMER:

THIS IS A SPARE E30 M3 REAR BUMPER, THE BUMPER WITH THE MATCHING VIN REMAINS AND WILL REMAIN UNTOUCHED.

THE BUMPER IS NOT NEAR FINISHED IN THESE PICTURES, AND IT WILL LOOK PROPER WHEN WE'RE DONE WITH IT.

I KEPT THE SPARE TIRE WELL FOR RESALE PURPOSES***

PURISTS NEED NOT APPLY, THIS IS MY CAR & I COULD CARE LESS WHAT YOU HAVE TO SAY! :

Anyway, on to teh pictarz!!!




Chris Castro inspecting his awesome work!



Nicely tucked up against the chassis!



And now onto the tips!




Yes that another s54 e30 sitting in the background



Mocked up and ready to finish tig welding everything!



We will be building a custom diffuser for the tips made from thermoplastic.

Exhaust clips and proper pics from my DSLR will be posted when I get back from Costa Rica in a week and a half!

God Damn Chris!! DO work!! Both of you Chris's. lol

[e30polak]

Purple M-tech seats are ready to be picked up!!!

[e30polak]

So I totally forgot to update the thread with the pics from Bimmerfest 2012. To make a long story short, the s54 I purchased for the swap ended up having bad rocker arms, damaged camshafts and damaged valve seats. The car made it to Bimmerfest and back but barely...

Anyway, the car is far from finished, but it made it to the show. I misplaced my kidney grilles during the paint prep process, forgot to get another set before the event....





Engine bay still needs to be cut and polished, but the whole car will be painted techno violet in the next couple of months.



As stated above, the rear bumper IS NOT FINISHED.






Anyhow, since Bimmerfest we took the head off the motor, and replaced it with the head from the s54 I plan to use for a turbo project. While we had the head off, I decided to order a one size thicker MLS head gasket and ARP2000 head studs, to slighlty drop compression and get the motor ready to be supercharged later this year!

Any how, we've been fine tuning the set-up and the car should be 100% by next week. The fuel system caused us some issues - both the in-tank and upgraded external fuel pumps took a dump on me. After that the motor started running wierd the other day, and we ended up pulling a code for the Vanos unit. Nevertheless, the car is a total animal! Much quicker then my previous bolt-on s52 e30! :

The s54 truly is the perfect match for the E30 M3 IMO! Despite the longer, heavier motor up front, I don't feel that I've really lost much in the handling category. The performance improvement over the s14 is night and day, but that was expected. I love how quickly the motor revs up and pulls through the powerband in each gear!

The exhaust is a bit louder then the s54 e36 we built with a practically identical system, which is exactly what I wanted! The induction noise from the open cold air intake almost overtakes the exhaust at hig rpms. It's truly intoxicating to hear those six throttles roaring with the hammer all the way down!

We're modifying our CSL style intake plenum with a provision for the brake booster I'm currently running next week. The CSL style induction sound, coupled with my exhaust system is going to make heavenly music! I truly couldn't be happier!

Plenty of pictures and videos to come in the next few months as I begin to post whore the car. The car is being painted "Hot Rod Black" for the summer, so that it looks decent for a few months before I decide I'm ready to paint the outside technoviolet. I plan to track, auto-x and drift the car this summer so I can truly enjoy the car the way it was meant to be driven. Once I have that bug out of my system, it will be painted and remain a street and show car.

Once the paint and clear have baked in after a few months, I plan to wrap the entire car in a glossy clear coat, so that I can track it with out worrying about my beautiful paint job! :

Thanks guys, I appreciate it!

I can't wait to molest the gas pedal of this thing. ;-)

Maybe on the freeway, don't need another Scarlet "almost" incident in the streets. :razz:

The car has been running since last weekend, and I took it for it's first real cruise yesterday. The Alpha-N tune currently on it is not meant for the factory intake plenum + intake we're currently running, but instead it's for our CSL style airbox. Chris didn't want to rush modifying my airbox to fit yet, so we left the factory modified plenum on for now. The tune is not ideal by any means for the current set-up, but it runs great from 3.5k - 8k!


Anyhow, I had some fun with some other cars this weekend, and I figured I'd post the results!


1. E39 540i/6 M-sport

I took the M3 for a longer drive Friday night to make sure it was ready for the 300 mile round trip to San Diego the next day. On my way back from where I was going, a clean Alpine e39 540 M-sport comes up behind me in a hurry. After driving the car for about 30 mins and seeing what my M3 could do, I laughed to myself when I saw the e39!

Anyhow, the e39 gets next to me and the driver rolls his window down, giving me a thumbs up. At that point I realized the guy wasn't the typical douche from Glendale. I hear him down shift and stab the gas real quick, and I was thinking, "why not?"

I dropped it into 3rd at about 70 mph, which is around 5500 rpms with my gearing and right in the fat of the s54's power band. Anyway, since my horn wasn't hooked up yet, I signaled him to do a 3-honk (he had no idea what was about to happen to him!)

He jumped a bit early on the 3rd honk, but it made no difference. I quickly made my way through the end of 3rd gear and shift at 8k, when I shift into 4th I'm over a car length ahead. After shifting into 4th, I walked away from him HARD! By the time I got to 120 I was probably 5-6 car lengths ahead of him!

I slow down for him and he rolls his window down asking the famous question - "What the hell do you have in that hing??!!!"

I yell out that it has an s54 from an e46 m3, and the guy's jaw almost hit the floor!

He gave me a huge thumbs up and said the car sounded amazing. Cool younger guy, that wasn't a sore loser.

2. Current Generation LS3 powered Camaro with exhaust

It must have been my lucky night, because about 5 mins after toying with the 540 I roll up on a new LS3 powered Camaro that was driving pretty fast!

He had either straight pipes or full exhaust, because the car was beyond loud!

It looked lowered, with blacked out wheels, with a douchebag, tatted up SoCal Bro sitting shotgun with the window down, and his tatted arm hanging out. I got on his A$$ real hard in 3rd gear and flashed him with my high beams. He immediately down shifts and nails it, we were doing about 80 before he punched it. He doesn't get any kind of pull on me, instead after shifting into 4th, I get into the right lane and slowly start inching across his car. I shut down at about 120 pretty much even with his car. He kept flooring it and probably let off at around 150!

I was pretty happy about this race, as my car still has some power left on the table and an LS3 powered Camaro is no slouch on the freeway!

So I also had some more kills yesterday at the M3 rally down to San Diego.

*** In all of the below kills I had my friend in the car who weighs about 250-260lbs, so let's just say I could've done better. ***

3. E90 M3 6 speed, with exhaust, with a 100-120lb passenger

There were a bunch of e90/2/3 m3s yesterday, along with some e46s, so I knew I could embarrass at least one of them!

Any how, I line up with one of them at about 65 in 3rd, which is about 3k rpms for me. The e90 did the 3 honk, and had a skinny teenager as a passenger. We stay about even through 3rd gear, when I shift into 4th I jump a fender ahead and start to pull on him till 120, where I was about 2 car lengths ahead!

The guy's expression was PRICELESS!

If my friend wasn't in the car and the guy lost his skinny passenger, I would've probably gotten at least another half car length on him.

4. E39 m5 with exhaust

So another car that was driving very "spiritedly" in our pack was a silver e39 m5 with exhaust. I knew he would be down to run, so I pulled up next to him. We were doing about 80, so I signal him to slow down a bit. I downshifted into 3rd at about 70 and signal him to do the 3 honk. On the 3rd honk we both go and I hold even with him till 4th. After shifting into 4th I put about a fender on him and slowly pull. I shut down at about 120 about 1.5 car lengths ahead. This was expected, as I know most e39 m5s are about even with e90/2 M3s, and he didn't have a passenger.

5. Bolt-on + tuned S50 swapped e30 , with a 150-160 lb passenger

So on my way back from San Diego with my friend Peter, we roll up on an S50 swapped e30 that we completed at the shop a few months back!

I had driven the car when it was complete and, it was a very strong S50. His car was running our short ram intake + airbox, s52 exhaust manifolds. full custom 2.5" exhaust we built for him, our custom tune for the set-up, coupled with a ZF 5speed and 2.93 gears.

We both say hi to each other and he was really excited to finally see my car on the road. He had a passenger that I met as well that had to be around 150-160lbs. Anyway I downshift to 3rd and show him what the car could do!

He comes after me and I quickly slow down. This was the real test for me, I had to gauge how much faster the s54 was then my old s52 swapped car (his s50 pulled almost the same as my s52 did). I knew I was quite a bit faster, but I'm wasn't sure by how much. Anyhow I downshift to 3rd at about 70. I knew our gearing would be very similar as he had slightly longer 2.93s, but I had a rev limit that was about 700 rpms higher.

He does the 3 honk and we take off. He holds even with me till he has to shift into 4th right before me, after that it was all over!

I hold it till about 125 in 4th and I end up 4 car lengths ahead!!!

I slow down and both of them were laughing and put their hands over their heads in disbelief!

Anyhow, I'm very happy with the performance of the s54! I can't wait for the CSL style airbox and a tune adjustment, so I can make a bit more power. After driving for so long, I also realized I will be switching to 2.93 gears. While the 3.23 is nice and torquey, it revs too high for me on the freeway. The 2.93 will also be more usable for me, as i will be able to downshift to 3rd at 80, and have an extra 10 mph to pull someone before having to shift into 4th. The 2.93s will also make 1st and 2nd gear even more fun!

I can just imagine how well your car pulls

such a beautifull motor

[ZammoTheChoppa]

Sorry for the thread hijack here but i clicked the link in your sig nice site BTW looks good

thinking maybe just maybe http://www.castromotorsport.com had something to do with Ryan Castro
so i went and read the about page and NO it doesnt seem to be as i assumed. Any way congratz on your achievements of motor transplants hope you guys kik ass with those lovely bavarian beast .

on a side not for those that dont know who Ryan Castro is





he built this car at the turn of the last decade. its still around now but diff colour and wheels but IMHO the way it is here circa 2004ish still embodies the everything i hold deer in a modified vehicle.
