Hey everyone, I have a 1983 jaguar xj6 sbc turbocharged. The car has been in the family since 84. Thought I would join to see some cool Jaguars.

Turbo pictures
Great, glad to have you with us.
How about posting some pictures of the turbo install? Any info on how it was done and brands etc. |

Please please please, more pictures!!!

Fantastic!
Any specs on the performance gained?

420/620 rear wheel on low boost. We built the kit and we stopped on the dyno because the a/r on the turbo was wrong. Moved up to a billet Compturbo and haven't been back yet. It's a monster! I run boost by time with a AMS1000 boost controller on CO2.

That is a thing of Beauty!
Welcome to our little corner of these forums. (';') |
Can you record the next dyno run, please,please,please....(with sound)

wow... really nice work and creative packaging. That Stealth Ram looks nice in there. I bet you were amazed it fit under the hood. How do you get it to hook. Any rear tire size mods? I have far less power and have traction problems. Were you able to keep the AC compressor? What heads?...what exhaust manifolds? What transmission? Ever run it at the track? I'm gunning for a F type coupe or time of 12.0 at 120 with my Chevy 406 project.

I use drag radials in the rear. I run boost by time on my boost controller and use that to tune traction. I use a Godley th400 with a manual valve body and 2600 stall. Built forged motor. Holley efi standalone.

Wow! I just Twin Turboed mine and well it may be 10% faster? Not sure why? Did you cam your too? any suggestions will be humbly accepted.
Just joined 1984 XJS SBC stock with Twin ebay GT35 Turbos. Was expecting 400- 600 HPS think I am at 250? https://cimg5.ibsrv.net/gimg/www.jag...ffddace97f.jpg Flow is good - Burns a bit ric https://cimg6.ibsrv.net/gimg/www.jag...6654018eb7.jpg https://cimg7.ibsrv.net/gimg/www.jag...3408cff70c.jpg |
Did you re-jet your carb after the turbos were installed? How did the engine run before you installed the turbos? Do a little research on the difference between "blow thru" and "draw thru" carburetor/turbo installations. The increased air flow and "blow through" setup without adjusting fuel metering in the carb could be causing your rich mixture. Look at your spark plugs to verify a rich/lean mixture.

It could be a number of things, what’s your air/fuel ratio? Are the turbo’s sized correctly? Being twin turbo, it should be efficient and spool pretty quick.

The installation of Nylonpunk will need more carb attention (modification) and fuel/air tuning than an engine with fuel injection.

Dave Installed 2 sets of smaller turbos .48 AR on the Turbine side/ .60 AR on the comprssor side - now I have compression on WOT and the blow through hiss after I let off the accelerator. My issuse is that the oil seeps into the turbo and the smokes at throttle. i have 40 - 45 psi on the oil pressure. So I put in oil restrictors and now thinking of lowering the oil level to reduce pressure to 30-35psi. THANK YOU DAVE will certainly take a closer look at the Carbs. Nylonpunk |
Sorry Just seeing this now. So I reduced the Twin Turbos to .48 AR Turbine side and /.60 AR Compression side and now they have compression. Didn't do a highway test yet. but they feel good on local streets doing 50mph. Still not seeing crazy power. next is to see if I can get it properly tuned by a pro. This should be interesting. I like in Northeast NJ, Bergen county any one know a good old time hot rod SBC mechanic near me?
