Soupcan, good find on the GTS heads on the BBC. There was an article in last month's Hot Rod magazine about that Ardema guy in general with his overhead cam hybrids, and showed the same street rod with GTS heads. Said it was a 427 block with "Porsche 928 5.3 liter heads". LOL. Never heard of a 5.3 liter GTS, but what the hell. It was still nice to see some positive exposureon the 928. The editors letter up front spoke very highly about the 928, yet very poorly about the 924/944 series.

I wonder who made the timing gears and how they are holding-up

Yes the factory built twin turbo marinised S4 engines for Jackie Ikxe to fit to a speed boat. there is one exhibited in the museum in stuttgart.

Tass is using a 16 valve engine for his boat project.

I have been contemplating putting my twin turbo 4.5 in something else, race car , boat, as now I am self employed I can not afford to lose my license which is what surely will happen when I get caught in my 928!

Cheers Roy

This engine sounds suspiciously like an engine in a Hot Rod that showed up at Sharktoberfest '05. The guy parked the car in the 928 Int'l lot & Keith Widom was on his way over to politely ask the guy to park said car over by the dumpsters along with the 944's. The owner opened the hood and showed everyone the "928 content" of his Hot Rod. There must be a picture of that car archived here somewhere.

I just stumbled onto this thread. I don't think the 928 engine is all about performance. I built mine into a 5.0 hybrid so I know it can be about performance. To me it's all about the cool factor. There are very few engines that look as elegent as they perform. I think the 928 should have had a see through hood. It's a shame to hide it under cover. I've driven my car all over the country many times. I drive it as hard as I dare. Great engine!

BTW: We call the second photo "The Money Shot" Check out the reflection in the rear lid.

^^^ Exposed cam gears, LOL at that.

I think the main reason people say "you never see a 928 engine going into anything else" is not because they're heavy, underpowered, or bulky, it's because they only made approx. 60-70 000 of them. Ford cranked out over 150 000 Mustangs in a single year, which would logically be 150 000 motors as well, but it's way over that because there are so many variants and rebadges that a Mustang motor is also in that Mercury over there, oh, and it's also in that Contour SVT over there. Same with Chev 350's, they've made over 1 million Chev 350's, simple economics. I can't find any exact numbers on how many Chev 350's have been made, but you know it's well over 1 million.

Another thing, why is it everyone doing Chev 350 swaps in 928's knocks the 928 motor so much?? They conveniently ignore the huge displacement advantage when comparing a stock 5.0 (303 CI) to a hopped up 5.7 (350 CI). How about you compare a 305 Chev to a 303 Porsche for once?

Rant over.

There are so many thing I like about your 914/8!

I hope that access panel behind the seats is clear.

Love the reflection! $

Actually more like ...."Finally superseded by GM's Generation II LT and Generation III LS V8s in the 1990s and discontinued in 2003, the engine is still made by a GM subsidiary in Mexico as an aftermarket replacement. In all, over 90,000,000 small-blocks have been built." So yes WELL over one million !!
Porsche thought the GTS engine as a replacement was worth over $30,000 when available so a fair comparison is to a $30,000 chevy ! There is a cool factor to having something rare and different just saw a Passat wagon with the 4 liter W8 all wheel drive for sale 275 hp but sadly automatic Limited production and rare often just means they were not able to sell the car when new !!! Not many people were willing to vote with their dollars.

cool thread revival...love that 914/8!

Why would you compare a 305 Chevy to anything? It was one of the most anemic motors they ever made. I don’t think putting a 350 Chevy in a 928 is a “knock” on the 928 motor. It’s just cheaper HP. For the price of rebuilding a stock 928 motor, I could have a 400 or 500 HP Chevy motor. Having said that, I have a 400+ hp sb Chevy and I’d never put it in either of my 928s.

ACTUALLY the Contour engine is not a Mustang variant but a Porsche one. It was developped for the Boxter and when they decided to use a smaller version of the 996 engine, Porsche sold the engine design to Ford.

I built my Alien because I wanted a car that I thought Porsche should have built. I wanted a V8 Porsche two seat pure sports car. It had to have a Porsche engine. A stripped down, light weight car in the spirit of the direction I think Porsche would have taken if they would have done this. Am I right? Hell, I don't know. But I like.

I rebuilt three 928 engines and never found them to be all that expensive to rebuild. If you have good core parts it's no more expensive than a chevy.

I even had a M28/11 block bored from 4.7 to 5.0 for $ 180.00 I never could understand why guys think it's cheaper to install a chevy. By the time you fit, convert and purchase all the adaptors, mounts, harnesses, hoses, and invest months of weekends in the garage you end up with a chevy you could just purchase. Like a Camero. I think it's far more of an issue of confidence and skill than money.

And sorry to pick up on a different part of a resurrected thread, but..

the interior shot of that ^^ Sbarro... Wow, just Wow!

"I understand that drinks at Club Tropicana are very reasonably priced..."

So you had the block bored for less than $200. How much were the new pistons?

Also, I believe you had to "fit, convert and purchase all the adaptors, mounts, harnesses, hoses, and invest months of weekends in the garage.." and you ended up with a 914. Albiet a completely awesome 914. That thing has "I'm really sorry officer" written all over it.

A very generous and helpful Rennlist 928'r helped out with a set of used pistons from a 32V engine. You can't run just any piston in the alusil block. As far as I know from my hunting and posting questions here on the 928 forum the special iron coated pistons designed by Porsche for the 928 engine is the only option. So, the cost is still in line with rebuilding any other engine.

Oh, and yes, I do have a 914-8 but it's all Porsche all the time. I can't think of many engine swaps that actually add value to a car except this one. Most are cute but cut the value of the car in half. Like a chevy in a 928. Sure there are a few that have brought some real money but most are just a novelty. Never really driven or finished to a high level or sort out all the issues associated with such home engineering.

I have been stopped by John Law. No tickets yet. Once they look through the engine grill and get to chatting it's like a jedi mind trick or something... You don't want to give me a ticket... I don't want to give you a ticket. You want to give me a warning... I want to give you a warning..
