My 86 GTS Drive

[Tradewind]

Finally got to test drive an 86 GTS Manual this morning, the sales person at the local dealer was very helpful and I can only recommend the local dealer (Autocorner Mackay) from this very short experience.

As is the case in our area most of the roads are flat and straight with the odd round about thrown in for good measure. The test drive was useful to decide on the direction of forced induction

The car gets up to any of the lower speeds very efficiently, the lightweight of the body does the trick, motor does seem dead through the midrange but is very willing at the top end of rpm range and idle to 3000 perfect for anyone driving the car in a town/city situation. The clutch is very crisp on the uptake and the gearbox pretty much flawless. Handling ditto - all good, brakes very good too

During the drive I tried to determine which method of FI would suit its character the best;

A centrifugal SC would give more of the same power delivery and while mid would be much better it may feel to be still lacking compared to a rip roaring top end power punch. Found a low cost method of install and easy too, not complicated like what is becoming available soon.

A screw blower would likely just make the car feel very awesome, like a potato chip with a rocket strapped onto it, the mid would be tough and top end still strong, car would then really push you into the seat from 2500rpm and BE impressive. Where to put it? yes there are some solutions but $$$

Turbo, I dunno, you set it up for some nice low to mid and then the top will lose its punch, set it up for better top end punch and then bottom to mid will lag and adding a decent ATA cooler is going to slow response all over again, which is highly undesirable for this ride. Not much places for a decent install of turbo (consider heat issues, drain back etc) and ............

So, maybe centrifugal is the sure bet for the moment, something that could be done for around $3600 in a box is whats needed

Enjoy the couple of pics, I am sure they are the same as many others

$3600??? really ? how do you put a price on that??? and does it come with any research and development? or is it just some cheap Chinese setup?

Don't underestimate trade wind he puts his money where his mouth is.
Having said that welcome and please put together a kit!

[Tradewind]

I am taking it more seriously than a couple of month ago. Have an installation plan now.

Have been boosting Subaru boxer engines since 2008, kits for many H4s and also H6s.

A 6psi kit can be installed for the near the figure quoted above if fitted at our Qld base.

Not everything has to be $6k + to work and fit perfectly

Thanks for the welcome Gambit - those who know about Tradewind know the score

Pfft, I'll scoff at the price and the lead time on it

If you're strapping a turbo to an NA engine down low response stays the same - 12.5:1 compression is massive. By the time you get into some positive boost you'd most likely be in the vicinity of 3/4k rpm - which as you said is the dead zone. Remembering the gears are quite short and engine speed increases pretty rapidly, power is always on tap if you know how to keep the engine in its power band.

I'm a massive turbo guy - but that said, in this particular case, centrifugal all the way. Twin screw would be cool - but it would be an absolute nightmare to mount. The only SC kits I can see coming out from any leading manufacturer will be a centrifugal kit.

Twin charge is possible for sure, its just a matter of $$$. You have the $$$ and you have the twin charger

We will go with an offer of a water cooled 6psi centrifugal SC system installed driveaway price of AUD$3800 + tune cost

That wont help anyone much except for those near to us in Qld Australia

Would that be a bolt on mod?

I'm interested in doing bolt ons to this car only so I can return it to stock easily.

[Tradewind]

Yes, I only do bolt on reversible stuff - ONLY.

Will you offer delivery on the kit only for the mechanically savvy to install themselves?

[BRAWL]

Sounds very promising and look forward to seeing what you come up with.
