Thinking of re-powering my SBC V8 car, In the planning stages need ideas for budgeting Options

[Rider914]

I have an LS2 crate motor with a new ProCharger (gear driven) supercharger, and FAST electronics (cost was $21k). There are zero miles, and would let it go for $15K. Would love to put the motor in a pre 50’s Chevy truck, but if you want to put it in a 914 (IMG:style_emoticons/default/smile.gif)

I replaced the motor setup with a 700HP LS7 (sodium filled titanium valves), with the computer and upgraded Holley fuel injection, it cost $34K total —with a 15% discount on the LS7 at the time. Additionally the chassis and rear end needed to support the power. Art Morrison created a one-off frame to handle the power and added a very sophisticated four link.

Is that LS7 in a 914? Wow

Hi.

Had a SBC in my 914 for about 15 years. Basically driven to shows etc.. Ditched the carb for a Fast EZ EFI system about 4 years back. Made a big difference in the drivability. Swapped out the 901 for a Boxster S 6 speed a couple years back. Shifts like a new car. Just installed a 07 LS2 this year. Major difference Much more civilized around town driving, Over heating issues seem to go away, Scary fast. Car is a narrow body with 5 lug, big brakes, chassis bracing etc.. In just the motor install I have about 12K.

Get a 915 with wevo kit for trans or a 930 4 speed with cable shifting like I have for my V8 car. The question is do you need that much power. I thought I wanted over 600 HP just because my 930 and 930 CVs can take the big power but a number of guys say that is just too much and the tires will never get traction. I have always thought more is better

Bob - Whats the rough price difference bettwen a prepped 915 / 930 and a prepped Boxter S? Advantages?

Thanks

930 is strong , but shifts like dog doo doo. Stay boxster S if you keep it under 600HP.

We've got an twin turbo LS6 914 coming out sometime around the end of the year and can tell you impressions then, but realistically its hard to put down traction much above 500CHP on the street on street tires...


See if you can get a ride in a 500hp 914. Its a different ball game than 375HP.

Yeah anything over 500hp is probably just mine is bigger than yours d*ck waving but you know I like mine to be bigger than yours. And I am used to sportbikes and the pull they have from 60-150. I just sold my ZX-10R that would rip your arms off at 100.

I am in love with the sound of the V8 with a heavy cam, it is the sound of my people so I wouldn't consider any other engine even if it is better...

Seems like even the sky isnt the limit for custom smallblock builds (IMG:style_emoticons/default/bye1.gif)
So these v8/914 cars im assuming would give
The 3.6 conversion ( not a slow car )guy all they could (IMG:style_emoticons/default/bye1.gif) handle ???

When is the 911 7 speed box coming

Id say overkill but you are talking 500plus horses

IMHO

200HP +/- 20 HP is a sweet spot for most of our 914's. 6 cyl 3.2L is (IMG:style_emoticons/default/beerchug.gif) .
Unless you're going to track your 914 just stay with what you have. I have about 365HP in my LS914 and it's a bit much for my intended use. As previously stated, LS 914's can be very civil. A bonus is if you add HEAT/AC....that's what I'm doing.

Currently 901, drivetrain is dialed in. I do have a Boxster S trans, mount , cable shifter ready to go in later.

Nice! I love the electric Cut-Outs - I have straight pipes from the headers on mine, no cat requirements here in Florida so it will sting your eyes lol.

I have many miles on my 901 (Crappy Tailshifter) and it hasn't grenaded yet but I would really like something with tight shifting and less worry when on the throttle.

I don't think those are Cats, just mini mufflers. I head this car a couple weeks ago and it seemed to have some sound dampening with the cutouts open.
I would go with the Boxster trans if I had the money. For my build I am going to have to keep my foot out off the line and use the 901. I found a used aluminum block LS1 with an LS 6 intake for just over a grand.
Have fun

Just remember that once you add the Boxster 6-speed, you have a bunch less space behind it than with SBC/901. And as some of you know, this pic is my car and it's AFTER the whole drive train was moved forward ~1.5 inches.

And if you opt to keep the trunk, muffler location starts to be fun. Think about Corvette exhaust manifolds as they move the collector forward and give you more room to play with.

Renegade is toting Boxster Trans these days as there are cheep and you can just pop a new used one in if you need it. With the big HP and engine torque if you are a rubber layer kind of guy the 915 and 930 boxes are going to hold up better in my option but we have race guys here that are using them in their cars. You have to look up current prices on the web for parts but you will be in for so much less money right for the Boxster trans. My 930 is set up with limited slip diff and oil cooling with pump. It is set up for racing and huge HP. 4 speed short length early ones

Dan has a 930 in his beast that is running, Andrew knows his stuff for sure so does Bob back east and a number of members, but if you want some current numbers today Renegade is more than happy to go over it with you on the phone. I paid $6,500 10 years ago.

Speaking of Andrew "knowing" his stuff (Hardly, google is my best friend (IMG:style_emoticons/default/smile.gif) )...

Heres a video of me going over the trans options and costs for the bare transmissions. I fast forwarded through the boring/non related bits. I know, I know.. I have a dull reading voice.
