Qingdao, sounds like you're staying pretty well on target for weight. As far as torque, you're aiming to have a bit more than I do, are you putting it through the 5 speed?
here is the info

Wasn't really aiming for anything LOL just kinda what happened. I went with the lightest cam that would keep the engine RPMS where I need them (just so happens its the best cam for stock heads). All this was done for supercharger noise and reliability; I didn't know that the 5 speed was so weak till after I'd made the engine choice. Had I to do it over again I'd put a Honda 2.4l four cylinder with a blower on it. That engine would be good and reliable and it would make much less power than the 4.3.

250 - 300 at the wheel seems like a correct number. Stock Vortec heads make about 50ish torques per cylinder at max flow, and I'm probably gonna have half an atmosphere pushing down on it. 75 per maybe then take into account my more than likely not perfect tuning. Cram 450 through a poor transmission 250 - 300 is a good estimate IMPO.


Yup, the el-cheapo 5 speed. Gonna put it to the test. I don't drag race or track my car, its just gonna be my new daily driver. Even if I have to replace the trans 5 times it'll still cost less than switching to a 6 speed. So after this trans goes, I'll just replace it and rebuild the old one. Keep the old trans on the mend while I break the one in the car.

JayG - I'll keep that in mind. Thanks!


Qingdao - I did the same thing. Though, if I had known the 5 speed's limits ahead of time, I probably would still have done it anyway because of how cheap it is. I can have three or four spares laying around for less than a 6 speed!

I'm facebook friends with the guy who races this rallycross boxster in England. He has an Audi 2.7 twin turbo in it and prefers to use the 987 5 speed. He goes through a transmission every year and told me he usually blows second gear out when he is coming off dirt and onto tarmac. The 987 gear ratio is similar to the early 2.5 gearboxes. My other friend with the 3.4 also uses the 987 five speed and both believe the 987 transmission is stronger than the 986. Externally it looks the same as a 986 gearbox though. I believe the transmission code on top of the bellhousing for a 987 is GAL

Does it take different axles? Bellhousing is the same I take it.

If the 987 5 speed is stronger than the 986 5 sped but it nearly identical, I'll keep it in mind. But they're also about twice as much as a 986 box. If I have an issue with blowing my current box too often, i'll consider it.

Quick google search, and they certainly look pretty similar, if not the same.

I talked to my friend with the 3.4 boxster that was previously a spec boxster. He works at Porsche of Plano and only works on race cars. He said that the synchros inside the 987 transmission are thicker, but everything else is the same as the 986. He swapped the 987 flanges for the 986 flanges because the 987 uses 10mm bolts and the 986 uses 8mm. The 1997-2002 986 inner cv joint is better for extreme angles and he's running 4 degrees of camber. He could have used 2003/04 axles (03/04 inner cv joints use a 10mm bolt with 8mm threads) but he felt the thicker 97-02 axles would last longer. The five speed is a good transmission if babied but you can't subject it to any kind of shock load. He uses the 987 5 speed because his car was already set up for a five speed, weight(6 speed is tough but heavier), and gear ratio.

So funny to see that much suspension travel in a Boxster.

One thing about the Brits is they are true enthusiasts.

Wizard - Rock on. That car has to be a hoot!

Apologies for such the delay in any updates. Haven't been doing much actual work to the car lately, other than driving it around, taking pictures, going to shows and showing it off.




(even in a line of classic Ferrari and Porschii, including a RUF Yellowbird, we still pull the crowd!)





But that doesn't mean we have been absolutely idle! The cheap oil resivoir we've been running keeps gurlging out the cap, so we dropped some real money on a nice Moroso unit. No problems since!

Also, the entire timeline of the car is now written on the hood. This started way back when we started racing it, as a way to keep track of who was faster. Now it includes all the work of the engine swap with dates. We plan to keep doing the lap time documentation, as well.



We have also decided to attempt a new exhaust setup. The 3" hater honkers were fantastic, but simply way too loud, even with the two Borla mufflers. So we've decided to drop down to 2 1/2 inch pipes. But that's not all! We're going to try 180 degree headers.

Yeah, this'll be fun.

Wait... took me a while but 501??? are you a Star Wars fan?!?

Yeah, I can't stop driving my car too. TOO much fun to drive and I'm so confident in the engine after I dropped the compression from 11.1:1 down to 9.0:1. I've put over 300 miles since I got it back together last weekend. 87 octane NO PROBLEM.

So when are you gonna weld those doors shut, remove the links and guts from them? You know all that unnecessary weight. LOL

Hahaha, yes! 501st, baby! Although, that was done before the new trilogy came out....

Gutting and welding the doors has been something we've been planning on doing for a long time. We usually just hop the doors to get in and out, anyway. We just haven't gotten around to it.

Glad you've been enjoying your car! You've got one hell of a cool build, too. I also really like the hardtop. I want one, though we'd have to massacre the rollbar for it to fit.
