Just got my Trickflow heads installed with head studs. I really like em! I can't wait to get my car back on the roadcourse so I can flog the **** out of the real expensive GT2's and 996 Twin Turbos and such.

Nice! Those things look super low to the ground.

How much do they weight and what is the suspension design front/rear.

Mcpherson front? Trailing arm rear?

It sits 41" off the ground measured to the roofline. It is indeed pretty low! These cars have always been known to be good handling cars because of the mid engine weight distribution...but were never known to be very fast. Stock 914's weigh 2000lbs. My car weighs 2500lbs and has 545HP (@crank) and retains the mid engine agility...but with a good bit of straight line speed as well. Yes, the fronts are Mcphearson struts and the rears are independant trailing arms. Weight distribution is 58% rear & 42% front (same as a new Ford GT). Lots of fun on the street and the track.

Can you list what transaxle you are running and what parts you used to get the clutch setup to work in harmony?

Also what brakes are on the car.... What size rims/tires front/back?!?!

That must be a capable of walking past just about everything on the road course!

Can you post some pics from under the car and also peering into the engine bay?

Very very cool build. I would like to do one someday. I'm surprised it weighs 2500lbs.... and not less.

Very Cool!!! I had a 914/6 I bought new years ago. It was a friggin' gocart on the street.

Thats looks like a badass toy.

Very cool indeed!! I'm planning a 500 hp ls1 with 930 gearbox in my convertible 914 beach boys Monterey conversion. Chasis has been stiffened with stiffening kit and tubular space frame welded throughout. Can't wait to get it done! This is a good forum, will be asking many questions about correct engine build/mods.

Do you have any pictures of the swap?

Great build, luv the idea. As to flogging the above mentioned cars, it's all about the driver, not the car. If you are fortunate enough to have the skills to out drive the drivers in those vehicles, then humbleness is the order of the day.

a fellow LS1FC guy I know saw this LS6 914 at a NJ trackday and said it was a total beast, I wish I knew were I left the pics, I'll see if I can find 'em and load 'em up to share, nothing much beyond cooling and engine bay pics but its a clean build and hells yeah it has to be an awesome track machine wow!

Nice to see some activity here with the 914/LSx conversion. I know that white 914 and have exchanged email's previous owner.

I'm currently in the paint prep stages of finishing my 914/LS1 conversion; all the mechanicals are done and hope to have it finished in the next two months or so.

I've also been helping a friend with his 914/ 500HP SBC/ 930 /street/trackcar (cage, fire system, etc). Been developing the track handling for some time now and I have learned quite a bit about the 914/V8 track handling idiocyncracies.

as stated on the Renegade conversion website, nothing better than combining the simplicity of the lightweight 914 and the lightweight simple LSx engine for an affordable exotic!!
Question I have, the c5 uses a rear mounted 6 speed gearbox (think it is the c5), has anyone converted this for mid engine use? I would think the c5 transmission would be better than the older zf's and 930 transaxles, and probably cheaper, more reliable?? Thoughts?

914montereyls1

Disregard my last post. The c5 has the gears ahead of the differential whereas the 930 (g50) has the gears aft of the differential, the g50 is better suited for the 914.

Andy1

I thought the white car has a 930; I see little benefit of going to a G50. The G50 will cost a lot more and won't be as strong.

I've wanted to do a 914 with a Hyabusa engine in it for a long time.

There is a turbo kit for it. Also, there's a guy in Florida that makes a block and crank and etc. that will convert two Hybusa engines into a V8.

I think with the 914 and that light-weight engine the handeling would not be compromised.

Hook up a set of paddle shifters and kill everything on the track.

Think of holding that gear to 14k rpm's.

914montereyls1

That hyabusa v8 is really cool, but quite pricey unlike the lsx engines. The hyabusa would allow one to use the 901 tranny...possibly, don't know if the input shaft could keep up with the rpm output of the hyabusa. 14k rpms is no joke. Has anyone tried the 915 transaxle with an lsx powerplant? The 915 are a good deal cheaper and more available than the shortbell housing 930.

Andy1

The 915 will cost some money since you'll have to re-gear it to suit the V8; otherwise the gearing is way too short. Additionally you don't gain a lot of strength over the 901. It is said that a 930 can take 700HP and the gearing is already pretty V8 friendly as is. My friend simply turned his 930 upside down which places the motor closer to the ground though it also places the trans higher in the chassis so you might need to cut out some of the trunk of the 914.

I know three guys that run a 930 behind high HP V8's and non of them have had any trans problems. Two of those are track cars so they work their trans' hard.

Though the 914 handles very well even by todays standards, it does have it's limitations. Newer generation mid engined prosches like the Boxster arguably handle much better.

I had a lengthy discussion with Bob Farnham from beach boys racing. His suggestion was to add some link bars to the trailing swing arms. According to him, the rear suspension will still flex even with stiffening plates (which mine already have). The body on my 914 has already been stiffened throughout, my worry still remains with the rear suspension. Why do I avoid the boxter? It already starts out heavier by 700 lbs!! And I don't think the body itself is anymore rigid than my modded 914. Besides, the Monterey beach boys body kit truly makes the 914 exotic with it's raked back windshield. I don't know, many different ways to get there, but I'm liking the path my project is heading so far. Just need a 930 and build up a good ls1 motor.

always wanted to do a 914 build love love those cars!!! Unfortunately, ever time I looked it's really hard to find a decent shell to start with that isn't rusted out. The cost adds up so fast! Plus the cost of entry on the trans alone is very expensive. If you can get a clean car without rust, you're looking at 10-12k at least in engine/trans/suspension/brakes.

914montereyls1

Merim123??? I don't know who is trying to rip you off, but you can get a rust free, running 914 ( w/ 4 banger) all day long for $4k. Need to buy one either from inland tx, az or ca. I got mine off eBay for $3700, California. It is virtually rust free with a beach boys convertible slant nose, Carrara 4 17in rims and a sub frame welded built by a NASCAR shop, and additional reinforcements throughout, also came with a hard top. Previous owner had a poked and stroked rover motor in it which blew up because of a stuck gas peddle, hence why I'm putting in a mighty ls1, maybe ls6. I'm pretty sure mine will be the first beach boys convertible with an LS1 engine. Enough about my project, look out for one in the west/southwest. Northeast....fur-get-bout-it!!!
