Hi,

I grew up with a Rabbit Mk1. I think about buying a Omni GLHS because it looks a lot like the rabbit and also has the things i miss on the Rabbit.

I have 2 questions.

1.the GLHS has 175hp, can you increase this?
How much can you get? What do i have to install? How much would it cost?

2.What is a fair price for a very good example? Near Mint/Mint

Regards,
Michael_

I Do not want to build a new car, so nothing so extensive like engine swaps etc.

I do not know much about the 2.2 maybe you can add a bigger turbo etc.? Would like to invest a few grands max.

So how much could you get?

I would plan on ten grand if you want to buy one that is near mint. I have about 8000 in mine so far and need another 2-3 grand. I have been replacing everything on mine including having Konis rebuilt (2000 to buy and have rebuilt). Its not cheap but it will be reliable and its been a blast learning about this little car. I will have over 10,000 in the car and it will be worth hopefully 7000. Granted Ill never sell it.

10 or 20 grand is a big difference.

How much hp can you gain for lets say 5 grand? and what would you have to do?
I would not like to invest more in performance upgrades.

These two questions are going to get a LOT of different answers.

First, you need a good starting point. Figure ~$5k for a decent starting point GLHS that is still going to need things like paint, interior bits replaced...etc, but be a solid car with good plastics and rubbers.

Performance wise, you can get ~300whp for less than $5k if you spend your money wisely.

Look over at turbo-mopar.com as well.

what does whp means? do you simply mean hp?
yeah 300 would be great, what would i have to do to get that, simply install a bigger turbo? i guess there will be some more changes to apply?

Okay thanks for the price info but i think i will rather spend more right for the base car instead of fixing issues like worn exterior and interior because i would like to have a original and good condition car.
So i guess i should be able to buy a near mint/mint one for around 10000$ ??? that would be great.

thanks for the link also, i did not know that site yet.

Edit:

My max. budget would be around 20k i would like to have 5k to spend for performance upgrades so i would have a max. of 15k for the car itself.
I think it should be no problem to get what i want for that budget.
but otherwise i do not want to spend all if not needed, so 15k for everything would be awesome, will see. :)

Turns out HP isnt that easy to make with the stock configuration but holy shit will it make some torque. If you add a complete exhaust system, down to a different manifold and put in 15psi you will be close to 300 ft pounds at the tire at just over 3,000 rpm. Then prepare yourself to drag some asses on the hwy. Change the computer to get you the 15 lbs of boost and a roller cam from a late model turbo car. The 86 has a slider cam or umm flat tappet style but the late models had a roller setup. All this for less than 1k in upgrades and you will be blown away.

You know what just buy a computer, turn the boost up, and throw some exhaust on without taking the manifold off. That will only be $500 and see how impressed you are. You will need money for 30 year old car repairs. Once you get to 300 ft lbs of torque 5th gear in the stock transmission gives up.

Another weak point was the (I think) 2nd-to-3rd gear shift fork. Dodge made a stronger replacement shift fork sold at the dealership at the time for use in the GLHS A525 transmission, which I had the dealer install under warranty after I broke the stock shift fork after dozens of drag strip passes and everyday commute to work.

My '86 GLHS was near stock with just Shelby replacement computer (smog legal all 50 states) that had slightly higher maximum boost and recalibrated tuning for stock injectors. No headers, no aftermarket exhaust.

It was a fun car to drive and I wish I still had it.

#1 your budget?.. seriously. your budget?.

#2 you goal.. most peoples goals are not a number of HP.. but and equivalent acceleration or better of another vehicle. do you want to beat your buddies civic? new velostars? new mustang GT's. or a hell cat?

#3 300WHP in a sub 3,000 lb car is 12.5 capable or better.. and 105+ MPH time slips.

#4 if you want three hundred HP dyno sheets. put in a fuel pump. remove exhaust. spray 150HP nitrous through it and hope the block stays together. 500$ total budget. (90% chance you frag the motor)

#5 a 300 WHP motor can be built. and stay together for about 5-7K if you shop. ( intend on rebuilding the engine due to age/miles/wear and not trying to boost a 30+ year old motor).

#6 dropping a 300HP motor into the car with out other modifications and preperation and support is a guaranteed way to have a 300HP motor in a car that wont move on its own.

#7 a new shinny 300HP engine wont be usable on A: stock cooling system B: stock fuel set up. C: stock trans ( for long) D: the open Diff( at the track) E: older axles F: stock computer/tuning G: used motor mounts

#8 you need a realistic and accurate budget approved by your S/O. You need a goal: super awesome dyno number one time. super awesome time slip one time. Walk your buddies XXX. make as much realistic and long term power as your budget allows. make the car reliable and fun to drive and safe to drive and stay together with as much HP as can be achieved while building it at budget level.

#9 you have said BIGGER TURBO a few times.. we get it.. you want a bigger turbo. no. you cant make 300WHP on the stock turbo( with out nitrous). Yes.. you would require a larger turbo to make 300WHP (with out nitrous).

#10. the intake manifold. exhaust manifold. stock exhaust system. stock intercooler and stock cylinder head are MUCH more of a restriction on these cars than a stock garrett turbo. the entire intake and exhaust track would need some adjustments and attention to make 300WHP reliably more than once. think of all those pieces as a system.

I have an 86 GLHS that I bought new in August of 86. My car was kept pretty much standard for 30 years except for the stage II MOPAR ECU. The car is fun to drive. With 210 hp, the car weighs 2,500 lbs. I would guess the 0-60 time is high 5 or low 6 seconds. It was quick for 1986 car.

I recently start to modify it ... my goal is to get 250 - 275 HP and a lot of torque.

The first thing I did was getting a 3" swing valve and exhaust all the way to the back of the car. I bought it from TurboUnleashed.com. I think it was $350 delivered. The result was quite amazing ... the turbo lag is virtually gone. Going from 1st to 2nd you can easily spin the front wheels. A word of warning, the 3" system has to be modified because it interferes with the shifter. The muffler shop did an excellent job by cutting a long piece into 4 segments and weld them back together to avoid hitting the shift linkage. With new catalytic converter, a resonator and a muffler (all of which are straight through) my car was fairly quiet. I spent $750 at the muffler shop. All together, the 3" exhaust system costs me $1,100.

My plan is to get
Wide band gauge $220, boost gauge $150, fuel pressure gauge $90, 60 GPM fuel pump $130, new 3-bar ECU probably 18-20 PSI max $350, a refurbished transmission A555 $650, transmission bracket adaptor $350 to allow the use of the current shift linkage. Total of $1,940.

I planned on keeping the turbo that came with the car.

Remember, you can enhance your car's performance by reducing weight as well ... it doesn't have to be about HP, but it's all about Lbs/HP.

I hope this gives you an idea for a budget.

I bought my car new in 1986 for $12,500 including Tax, Title, License.

I say, if you find one in good condition, it will be upward of $15,000.
