Itr 300zx

[JeffYoung]

I bought a car, and will start a LONG build process (focus is still on the TR8 for several more years).

Anyone else working on one? Email me at [email protected] if you want to swap ideas.

Whooo boy. subscribed.

I'm thinking Jeffy got a raise at the firm. If he didn't, he'll need to!

[JeffYoung]

You know, after spending a lot of Saturday looking at parts and pieces, it ain't too bad. Junkyard running motors at $1k, built ones from Z1 at about $4k. Brakes, not too bad ($250 for a set of Hawk blues all around). ACT 6 pack clutch, about $500.

Plus, you can get running cars here on C-list for $3-4k all day long.

Just that damn weight. Jake, fix it!

[Ron Earp]

I think Jeff is correct in that these aren't horrible expensive cars to purchase and build. Parts seem "reasonable" - not old Z car cheap, but not Porsche expensive either. The weight will cost the owner of the car though - it'll have to eat up tires and brakes faster than a car that weighs 800lbs less - the ones we're driving now.

Cool car, look forward to helping build it.

[lateapex911]

Sure, Jeff, I'll get right on it!

And we know those engines are just limp wristed motivators that have no torque and run out of revs, right?

[JeffYoung]

They are an interesting beast that VG30 or whatever they call it. Most show about 180 whp and 175 wtq stock on a Dynojet, with the torque curve VERY flat and the hp rather peaky and not reaching a crescendo until 5500 to 6500 rpm.

Gains from simple stuff does appear to be substantial though. Deleting the clutch fan and replacing with an electric looks like about 8-10. Stillen claims 16 whp for their headers. Stock intake is restrictive, some gains there. I'm sure with a reasonable IT build about 220-230 whp and the same torque is acheivable.

Car seems classed right to me:

222 stock hp X 1.25 gain x. 11.25 hp/weight = 3120 plus 100 or so for aero and suspension.

This should be a bread and butter car for the class.

222 stock hp X 1.25 gain x. 11.25 hp/weight = 3120 plus 100 or so for aero and suspension.

I think that one is assumed at 30%

[JeffYoung]

That would explain it, and probably accurate too based on what I've read.

[Ron Earp]

Whoa whoa whoa. Hold up.

Since when are you one of us Nissan boys? Now you work on one and all, but that doesn't mean you get to join the lofty ranks of Nippon Race Machine drivers.

I think we're going to have to class something British in ITR to keep you in your place and I have the perfect candidate - the Triumph Stag. You won't have to change your trailer paint colors, lettering, or anything.

I'll write the classification proposal tomorrow. There aren't any objections to V8s on the BoD or ITAC is there? I knew they were open minded and all....

[JeffYoung]

No Stag for me my friend. TVR Griffith maybe.

Can't find any recent 2wd Jags with manual tranny's (the S-type would have been a good candidate). Maybe a Lotus... What year is that Elise? Same engine as the Celica already in R right? Probably run about the same weight... 400 lbs over stock.

Edit - maybe more since the Celica has a FWD subtractor

[JeffYoung]

Hmm...is tough to think of any Britshit in the 190 to 240 stock hp range.

Elise/Exige, same as the Celica motor, just lighter cars. They would be in R I suppose.

No TVRs sold in the US since the mid 80s.

Aston Martins -- all could be had with 5 speeds and V8s, but too much power.

Rover SD1 Vitesse was a great touring car race car, and 190 stock hp, 220 stock torque, but not many here in the US.

The pickings are slim. Which is a GOOD thing....lol.....

I know we're all joking here, but these cars couldn't go into R. They would need too much ballast to meet process weight. I wouldn't be surprised if the GVWR is less than process weight.

[JeffYoung]

Yeah, probably what, 400 lbs? My Exige is 2000 lbs curb weight. So maybe 200 lbs once you account for driver and gas. Close to doable but I agree the ballast required is a lot.
