Boxster V8

[DarkStar]

BoxsterLS376, Thank you! Maybe its just me, since I've done chevy swaps on Fords. Big Turbo 4cyl Mitsubishi Swaps on Geo Metros and built cars with drag slicks up to caged toys with 44" Tires, beadlocks and 1 tons. Fab work isn't something new to me. And I've followed your entire build and the cutting you've done is minor! A lil fitment cutting and a new cover and its in.

I do agree with BC, the Renegade "Kit" is a hack. But its pretty well built.

350whp... Enough.... Hardly but to each their own.

I'm not against this proposition. I'm actually highly interested in seeing it grow. Porsche Performance just isn't reasonable. There is no logic in spending a ton of money for hardly any gain when there are options for spending less for more gain.

Like BoxsterLS376 Said, he went the WAYYY expensive route. 8 Grand For only 480hp, But he got a warranty (ehh, not bad). I love his build and hope to speak to him soon regarding my swap. (Yeah you still haven't responded to me on youtube :'( lol) But as I said earlier, Junkyard 5.3L Cast Iron (80lbs heavier than the aluminum block) or 5.3L Aluminum LS Engines, can produce 450whp with no turbo on them. People are doing it every day in old muscle cars by cam, head work, and some tuning. And thats daily driven reliable. You can pickup Stock LS1's with Transmission, Harness and ECU these days for 1200 bucks from Trans Ams, Camaro's, GTO's.

The reason were arguing the fact, is because say you do fail.... Its not that big of a deal. As I've stated a few times, I've been in the car world, building cars that is... for quite some time. Things can go wrong. How much is it to fix said wrong, with which motor. I can think of a few other engines that can produce 1000hp, save TONS of space and are a dime a dozen in the world, But reliable.... Not soo much. Can be! But risky.

So your current 250 hp has been enough for ?? 14 years? To each their own HA HA.

"Anytime you take a motor from one car and put it into another you are going to run into problems and it is going to take a lot of fabrication and figuring unless someone makes a true "bolt in" kit, which to be honest I don't think will ever happen."

bc993:
As you know I've been following your thread from the start.
WT#! You mean you're not going to give us a KIT?
I'm a Network Engineer - Business Development guy. My fabrication skills are non existent. Have no trouble changing oil, spending a weekend updating suspension parts but that's it. I spend my free time driving my car, golfing, flyfishing in spring/summer and shooting ducks/pheasants in the fall.

Also wanted to chime in about the price/platform... First off starting with a base boxster is just dumb. dumb dumb dumb. The S suspension and brakes do OK "

bc993:
Have to disagree with you. The only thing the S brings now is the 6-Speed trans.
On a 15 yr old car I'm going to replace the suspension 1st thing.
ROW MO30 or PSS9
Front Brakes can be bolted on: 996 or S Calipers (no need for rear imho) just need to update front rotors.
Also GT3 control arms

Now the only other issue for base vs S is the radiators. So I would do exactly the same thing you did and replace 15 yr old radiator with S radiators.

I have found some almost perfect base boxsters with like new interiors and near perfect original paint and it would cost me much more to find an S in that type of condition.

Yeah sure you did but your boxster still only has 250 HP right?

Ahh yes I remember seeing your post on Youtube but to be honest I don't have time to respond to things in more then one place which is why I redirect people here to ask questions! I don't recall your exact comment but based on your statement think I recall...

It's not to say a used motor wouldn't be just fine for this, but there were a number of reasons I went the route I did. The key word in your statement is "CAN"!

First off I don't know where you are buying complete LS1 motors with transmissions, ECU and wiring harness for $1200, cause they ain't that cheap around here!!! I'm sure you "CAN" find them out there for that price, but very few and far between~

For reference a quick Ebay search for LS1 engine will show the cheapest engine/trans out there right now is $3000 with an automatic... perhaps you can get a complete 5.3 for that price, but regardless, what are you getting for that price?

I wasn't going to bother doing this project to put a 300HP motor in place of the 250HP motor, plus what you are getting for that price is a used 100K+ mile motor and while the motor itself may be good for 200K or more, all of the little things on the motor have 100K too so you will start to have issues like coils going bad etc.

By the time you take a "junkyard" motor, rebuild it to a point that I would be satisfied with it from a reliability (bearings, seals etc.), and satisfied with power (400+), you can easily spend more then the $8k I spent on a brand new motor, that makes 480HP, and has a warranty AND I DON'T HAVE TO PUT ANY EXTRA WORK INTO!!!!!

The math is simple... just the basics and doing the work yourself~

Used LS1 motor = $3000~
Built cylinder heads = $1500~
Big camshaft = $600~
Rebuild kit = $800~
Upgraded rockers = $500~

Assuming that your used motor came with ECU/wiring then I would have spent at least $6400 to rebuild a used 100K mile motor. That is assuming that everything else in the motor is good and it doesn't need any major parts or machine work.

Could you just buy a used motor and throw it in, sure, but part of the idea was to make an easily replicated platform to build these cars on. It is just easier to call up Chevy and say SEND ME THIS.... and cut a check, then it would be to source used motors, rebuild them and then deal with the possible problems.


The thought process behind my build was to come up with a reasonable replacement for the lousy motors Porsche put into these things, that could be easily replicated.

Let us also not forget how much more money you have to spend on the little things which do add up fast... Motor mounts, transmission mounts, cooling and exhaust system, which I'm afraid to add up lately cause I already blew my budget but was something like $5-$6K... SO FAR. Car is almost done, but that is just the conversion.... I haven't gotten into brakes, suspension etc.


I definitely applaud what the NERV guys are trying to do but question their logic on many things... time for another post~
