I should also add, that for about 800 dollars more, they offer an LS1 kit. They also offer for 7500 a brand new LS1 motor that has been designed to go work seamlessly with their kit. It includes the FI system and everything else needed, including the harness and the tune. It is tuned conservatively for 425 hp.

Have you ever opened a 928 motor?
Do you know what the internals look like?

These motors are VERY strong.

And how many miles does that motor have on it?
I boosted mine at over 240k miles. These motors take a long time to break in as it were. Look at the GTS. Its oil consumption tends to lessen after 100k miles.....

Your 928 already has coilovers....and a double a arm front suspension The point was that as the power increased on the 928 so did the brakes....78-82 small , 82-early 86 medium, 86.5-92 real big, 93-95 Huge..front calipers rotors .... Frankly, you do not know enough about a 928 to "improve" it.. Try reading more and posting less.

I know that it has front coil overs. I wasn't aware that they were up to race spec. Forgive my ignorance. I am sorry as well if all of my posting for some reason annoys you. Of course, you could just chose not to read them.

That being said, you have just confirmed what I was told by renegade, that the 928 is worthy suspension and braking wise of a big v8

Build your own, that's a terrible deal. Pick up a 6L out of anything with the controller and wiring harness. They are about $1000. Put a LS3 intake and heads on it. That with longtubes, a 0.610" cam, and all the rebuild parts will cost you around $5k. It will make 550hp.

do you think the auto trans (assuming good condition) from a 1980 will be able to handle 550 hp? Are you talking about flywheel numbers or to the wheels?

I really like the new Edelbrock e street Fi system. it is fully cockpit programmable via bluetooth, and allows you to run efi with any 4150 flanged manifold.

I think Im going to build my own though for sure. Iwas just thinking I would save myself the hassle of doing so and order one. I may just order a shortblock and figure out what head combo to use.

What Quattro said. A 6.0l with Vette intake The iron-blocks are only 70 lbs heavier than the alloy blocks (my engine builder weighed both). It is easier to convert a 928 than a 944. Renegade is not the only hybrid parts builder either. Eric at TPC has done a few LS swaps(using 928 trans).

The automatics are stronger than the manuals. It should be fine. I was talking flywheel hp.

The factory GM controller is light years ahead in technology and performance. EFILive and HP Tuners both give full cal access.

I just think that I can put together nice 928 with a 400 hp fuel injected reliable motor for 10k
ledee416, circle back to very early inputs that directed you towards a more realistic $$ expectation than your original statement for a "$3k kit and an engine for less than $3k".

Yes, you can do a lot with $10k, which is much more realistic than you initially estimated ...at least you are hearing some of the advice. The Renegade kit should work very well for your intentions and a $10k budget.

btw, it better be much more than 400hp for that kind of money. IIRC, a 5.3L LM engine with intake+cam swap will yield 400hp, so 123quatro's suggestion seems smartest to consider.

Good luck!

I might have mentioned the S4 first as an alternative to your power quest, but I was not referring to putting an S4 engine in your OB. That would be a big pain in the *** too. I think the smartest move is to get your car running, sell it and put the money toward an S4 or later. Then do a modest low psi. SC kit and I think you will have all the overall street performance you could expect for the money invested, and you would have a car that can still get over 20mpg (what will a 459HP 350 carbed engine do for miliage?).

The '80 you have has the weakest 928 brakes of any model year. This '85 5-speed in California has better brakes - although still not as good as the Brembo 4-piston late 86-91 brakes, or the 92-95 brakes. Given you can get a repaint pretty cheaply, and will be replacing the engine, this car would be a decent starting point:

http://orangecounty.craigslist.org/cto/3346435481.html

The cheapest 500hp car would be an S4 with a supercharger kit bolted on. As soon as you get into swapping engines, ECU's, etc., it gets tricky. Dont take Renegade's words for it - they're greedily eyeing your wallet. Not to say their kit doesn't work - but it does leave a lot of questions unanswered.

Some questions for you.

What PS pump, Alternator and AC compressor would you use, and what hoses/fittings/cables to attach to them? How will you integrate the speedo, cooling fans, and AC wiring with the new ECU? What hubs/spindles and brakes will you use? (the stock brakes on your current 928 are not good enough for 300hp in the factory's opinion - they used stronger ones on the '80 Euro 928S which had 300hp). Sorting out those questions is, at an experienced guess, $2k minimum.

Note we're not trying to say you're mad for wanting to do this, or stop you from doing it. We just don't want to see another person jump in with enthusiasm only to wind up hurting when it isn't all as easy as optimism suggested. You wouldn't be the first, and won't be the last, to dive into the 928 as its a great looking car, with no real plans or planning, and wind up selling a partial project for pennies on the dollar years down the track. Remember we're all car guys here - we're not "modification police" and we just hate to see other car guys get burned.

There are some excellent conversions driving around, and the results can be good (there's even a twin-turbo 2JZ toyota motor in one locally), just be aware that its not as simple as Renegade make out.

Seriously - take a step back, make a spreadsheet and itemize/estimate all the things you think would need to be sorted out in the project. People here will be happy to discuss options, costs and process with you - this forum is full of a lot of experienced technical help.

In the short term, find a local 928 owner with a well sorted car and go for a ride in it with them. You might find that an almost stock 928 (exhaust mods and possible ECU chip) with better brakes is enough that you don't need to spend thousands of dollars for a small further gain. For the cost of an X-pipe, a fuel pressure regulator and some ECU chips, an 85/86 early 32V can put down 300hp at the wheels. Compared to the cost of a complete engine swap for a 400-crank HP engine, its a no-brainer.

As rgs says in the quote above - get your current one running and sell it to replace it with a better starting point. You should be able to upgrade the whole car (and increase your options) for less money than the cost of just upgrading the brakes will likely end up on your current one.

Welcome to the forum.

What are your goals for the car?

What do you plan to do with it?

I see you have mentioned more power, but to what end is more my question, road racing, drag racing, more of a what do you plan to do with this "more power" you want?

Regards Renegade I would examine their products closely and only use a few that could not be improved on. I would also skip the Chevy motor for a Ford Mod motor. Whats the point of doing the 273rd Chevy swap into a 928?
