mmr 4.75 stroker n/a hp?

[MMARAUDER]

Let's say I swapped this out with my stocker, what would my n/a hp be? I have bigger plans ahead for this engine but for now I'm just wondering. Thanks for any info.

[SpartaPerformance]

Their web site seems very vague as for specs unless I missed something I didn't see expected compression ratio, kinda hard to determine power based on what they have listed.

[MMARAUDER]

Lol yeah I know I looked. You would think they would do that for comparison.

[dohc324ci]

Its custom built to your specification. I am making 331rwhp/371rwtq from the BOSS50 MMR Stroker 900s 10:1cr. For that setup though your going to make close to stock; essentially a forged motor.

[MMARAUDER]

Gotcha. Thanks for the info. I wanna do a turbo build later on. So I want to get a strong setup.

BTW, their HP ratings are based on the series, example MMR 900S the rods will support 900rwhp; 4.75 stroker 750SE should be 750rwhp. Talk to Mark over at MMR to let him know what you intend to do so they can build to suit.

This is what I'm goin to order.

MMR 4.75 Stroker Mod 1000 Stroker Rotating assembly

Thisis everything you need except a block to assemble a complete fully forged shortblock, this kit has the same parts as the MMR Street Mod 1000 shortblock but in a do it yourself kit. Available in all piston oversizes for 96-09 2V, 3V and 4V applications.

Includes:

1500 HP Forged Steel Racing Crankshaft (6 or 8 bolt) by Kellogg 100% US made - NOT CHINESE like EAGLE or SCAT!

MANLEY 4340 Forged H-beam Rods with ARP Bolts

MANLEY Forged Pistons with tool steel Pins

Total Seal Rings

Clevite Performance Rod and Main bearings

High Volume Oil Pump for 4.75 crank

1 year Warranty

[MMARAUDER]

I got the cobra block about to go to the shop for a .20 bore got bare heads ready to port. Slowly collecting for the rest of the build.

[ctrlraven]

I was looking at the 4.75 and 5.0 stroker kits. I decided not to go the stroker route and go bored. Got a Boss50 block, will keep stock stroke but when all is said and done I should be 5.1 306ci and about 10.3 cr.

[MMARAUDER]

Yeah Ima go with the 4.75 its a pretty good price.I got the block and heads stupid cheap. Ima go with a 9 5:1 cr with 60mms

[Blk04MM]

Who's going to fab your turbo setup?

Nice how did that go?

[MMARAUDER]

Place here around Orlando called real street performance. They mostly play around with ricers but can custom build turbo kits.

Just piecing parts together right now, have to get some different compression pistons, main bearings and valve train stuff for the heads then off to the engine builder.

What's the price on it

[MMARAUDER]

What's the price on it $80 per hour

[Vortech347]

Only crappy thing about the big bore is you move to an iron block. But a bigger bore is the way to go. Modulars have horrible tiny bores.

I'll bet it won't be cheap.

Zack is doing a turbo on his blue car and from what he's posted up over on TCG, it's been a real PITA so far, fabbing is tough on our cars due to space constraints.

[MMARAUDER]

I was lookin at doin like a hellion setup. If not possible a sts type setup

I've been watching Zack turbo build. Yes he said its been a PITA and that's probably why there isn't a marauder kit due to so many factors. I wonder if he will sell kits after he is done.

[Blk04MM]

Hellion doesn't make one for our cars it's "universal" on their site. And I've read here the STS just isn't good enough. But I'm not knocking your plans for your car. I'd love to see a turbo marauder. Only one Ive read up on was a PTK kit in a black marauder a few months ago online

[MMARAUDER]

I know hellion doesn't make one for our cars I want one custom made to be like it. And I heard sts is a good system a lot of people worried about lag and oil feeds. But I'm gonna go with comp turbos they have a oil less turbo so if I did the sts style, no oil lines or scavenger pump

[Vortech347]

Sts systems are garbage

[blkZooM]

Ill be using this rotating assembly, with the FRPP 5.0 Boss, as the foundation for my future plans

[LANDY]

Sts systems are garbage
I wouldn't generalize that statement. My buddys vette has had an sts kit for years with no problems. He actually races his car!

For every "good" review I've read about those kits there are 67 "bad" ones. Some people actually luck up and a sts kit works out fine for them. Most times I've read it leaks and breaks motors.

Sounds good 76mm?

Check out this thread over on TCG to get an idea of what you're getting into:

$80 per hour

Per Zack, "First off, I now understand why turbo systems cost so much. I give a ton of credit to the guys who make artwork out of pipes....**** aint easy. It took me about 10-12 hours just to accomplish what you will see in the following pictures. Anyone thinking about doing a DIY turbo in your Marauder, I strongly suggest you to reconsider!"

Better plan on at least $2,500 for pipe fabrication unless you can DYI...

[LANDY]

Sounds good 76mm?if he is doing twins that would be too big. Twin 57's should be perfect.

[MMARAUDER]

I talked to nthe10s and he suggested. 60's.

I've been all over zacks thread over there and while he is a god in our marauder world he doesn't custom build and work on turbo kits for a living. And like I said if it gets too hard for these guys then........ http://www.youtube.com/watch?v=Gkt2opFyDOI.

But seriously though thanks for lookin out.

Nothing wrong with STS systems if done right. So sick of hearing all the negative feedback from people never even owning one, not too mention never knowing why they failed. There is a damn good reason why some make insane power with years of reliable service and some are crap. Proper sizing is key and if sized wrong, or cheap parts used will create the most inefficient combo you could dream of.

There is a V6 mustang around me that will get absolutely STUPID at 40 in about equal timing as a roots blower!

"But mustangs are shorter wheel base" B.S. Their mufflers are mounted right at the bumper VS ours nowhere near that far back. They don't weigh all that much less, and engine to bumper pipe length isn't all that much of a difference. Some here make it sound like we roll in F350's. Pulling trailers.

Besides, we have a lot of property along side the trans and I bet the bank you could fit a pair bolted right to cobra logs or shorties using liquid cooled units tapped right into the back of the heads.

Again, they are garbage. Line him up to a comparative propper turbo kit and his novelty item will get roasted.

Every STS kit I have dealt with was a fail. Slow. Poor to tune. Low numbers and aweful drivability. The company itself screwed over a good friend of mine on her build with empty promises and a blown motor. I'm local to them and in their own back yard they are a joke. Not a single car worth a **** here with an STS. Horrible company and a horrible product. If they were worth a damn don't you think they company would have grown? Nope, it didn't. There is a reason Vortech, Paxton, Procharger, Kenne Bell, Hellion, ect. do well. Its because their products work!!!

Justbob if you feel the kits are so superior why did you do a trilogy? Right. You wanted to go fast and have it work right.

My feed back is first hand from installing and driving STS products.

Superior? Hell no. Impressive for what it is? Yeah. I went with mine because I got it for half the price as new and 100% complete with low mileage. I am hooked on nothing and could switch my entire set up overnight just for giggles. Trilogy's get boring quick anywho. 😉

A midget bench pressing a small car is impressive. STS is nauseating at best. You should prove me wrong and do one of their kits.

[justbob]

Can we just agree Bridgette is impressive?

[na svt]

The 4.75 stoker is only marginally larger than a stock stroke 4.6 so don't expect big gains, in fact the power woudl be very similar to that of a .030" overbored stock stroke combo. As far as MMR goes...run away! I've seen none of their n/a engines make good power. A 3.75 or 3.8" stroke using the aluminum block is the best option as it does not add 80lbs to the front of the car like the Boss block.

The only STS turbo car I ever rode made 630 at the wheels and ran 10s (full weight, manual trans camaro).

[MMARAUDER]

I was just gonna get the rotating assy and toss it in my cobra block I recently purchased

[ctrlraven]

The only reason why I did not go with a stroker kit is that I want to have my engine built and ready to drop in for the person who is doing my install and make things a lot easier and simpler for him. All that will need to be done is swap over accessories and it will be ready to drop in.

The installation process for a stroker is exactly the same as that for a stock stroker engine.

I know that, what I meant was so that the person doing my install didn't have to lug my old motor to the engine builder and pay more in labor for tear-down & rebuild. I have everything for a complete motor now, get it assembled and will have a direct swap/drop-in replacement. I want my old motor untouched until I get it home and get it up on the engine stand. I plan on doing a detailed documented tear-down of a still well running 4v MM motor with 200k or more miles on it.
