Hey future friends, I'm a newbie but have been reading the posts and hope that somebody may have some idea's. A friend of mine is buying a Nissan 300 ZX twin turbo and is putting me on notice that He is going to come looking for some Corvette. Any idea's on what the match up will be like. I am pretty much stock 1988 Auto with gutted cat, muffler elims and 160 thermostat. I have also picked up ac rapid fire plugs and msd 8.5 wires with new cap/rotor (picked up from other post comments). Any thoughts or suggestions would be welcome. Thanks

It might be close.....as long as he hasn't upped the boost on that thing. :skep:

vvv90, Both cars are auto's. the 300 zx has a performance exhaust added on, I do not know what type, will see the car possibly Saturday.

I have owned both, you may be in trouble, I had a 5 spd and an auto TT 300, they were pretty quick, no low end torque though. The Vette will be stronger on the low end. Others may have actual race experience, i do not, though I have done most every repair imaginable on them...not much working room...

Have had experience with both back when I was stock running high 13s. Neither one could hang worth a damn off the line, but the TT would finally start to stick around 60mph and hold the gap steady.

Beach Dude

Hey, I appreciate the comments, sounds like I would want to do this from a standing start and defintley not on a roll. Any quick and realtive easy mods anybody would suggest to stack the deck in the Corvette's favor? :flag

If you ArmorAll his tire treads you might have a chance. He will be passing you at around 80-90 mph. His 50hp will show up about then. However you car looks a lot better.

Yeah....

Street racing is a lot psychological.

The first one ahead and steps on the brake so the other driver can see your brake lights, wins (if no distance is specified).

You've had your car awhile I assume and have practiced launching. New TT driver's have no clue on how to launch a turbo car well. Even experts have trouble at times. Autos are really difficult. Specify from a dead stop and you'll have him covered but don't race for more than a 1/4 mile. Like someone said, those extra 50-60 horses will eventually catch you.

I've seen tricked out TT's with over 400HP that either bogged off the line or went up in smoke. The hole shot is your ace in the....er....hole. Take advantage of it.

IF your tranny wants to shift after the engine runs out of steam in first gear like mine did, freeing up the intake will help that. It's not the cam. I couldn't rev past 4900 RPM no matter what I did until I started with the porting. A runner change is the quick fix but there's several pounds of AL dust that needs to find a place on the garage floor, from the heads to the TB.

Just remember, street racing stories are not allowed on this forum anymore, so if you don't take it to the track, you won't be able to share your experience.

BTW, I've raced two of those turbo 300's and beat both of them, neither could cut a light and neither could launch the damn cars.

They were both dialed in a full second or quicker than me.

A few quick things that may help are keeping your race weight down...go with 1/3 or 1/4 tank...should save over 80lbs...your muffler elims are probably a 20 or 25 lb reduction. Also, take the spare tire out of the back (I don't know what the weight is but it should be at least 25 lbs) and make sure that you don't have a passenger in the car. You could do some simple permanent mods like cut the air lid etc. Don't spin off the line and you should take him unless you are going over 100. :chevy

OK guys, I thank everybody for their thoughts and support, yes I have thought about adding spray, but I don't like the thought of losing what valuable cargo area there is in the back and putting a bottle back there. Mr. Mojo, I'm glad you said something about posting about street racing because I didn't know the rules. As a police officer told me one time, ignorance of the law is no excuse, thank god I wasn't street racing. Should have a idea on the 300, he is picking up Saturday or Early next week, WIth any luck, he won't be completly comfortable with launcing. Any other thoughts, I am willing to listen, the stock thing is getting old, but need something that would be reliable and approx 18-20 mpg. car gets approx 30k on in a year. 383 stroker keeps coming to mind. Thanks to all. :flag

My boss had a stock '94 LT1 6-speed, and he raced a stock 300ZX twin turbo. He said that he couldn't beat it, no matter how hard he tried. And he's a good driver too, so I believe him when he says they are fast.

I have a L98 6-speed myself with the usual 'easy' mods - no MAF screens, cut lid, K&N filter, no frisbie - and I wouldn't want to mess with one. At least not with the type of mods that I have.

Now, if I had an LT4 Hotcam kit, 3.90 gears, ported heads, TPiS big mouth/ported plenum and runners, 52mm throttle body, and full exhaust system, then maybe.

In addition to those good weight reduciton suggestions try these mods:
-remove the "frisbee" from in front of the water pump
-install cut-back spark plugs
-gut the two pre-cats
-install a low temp fan switch (heat is your enemy at idle too)
-install an adjustable fuel pressure regulator and tune for best 1/4 mi trap speed
-adjust base timing for best 1/4mi trap speed
-install a K&N with cut lid

Finally, take your friend to a 1/4mi drag strip and get the time slips to prove the issue.

If you're prepared to consider a comparatively major mod like a 383, another thought is change diff ratios. I have a 3.73 in my 89 and it really takes off.
