Harrop TVS86 Owners Thread

[tzbang]

My car has to go in for the valve spring recall. So that means engine out. Do you think while it's out I ought to pay Toyota to do some preparations for the SC? I was going to get them to replace the spark plugs anyway.. but now I'm wondering if I should get the clutch done, seems some people upgrade the clutch, snout and bearing when they go FI ?

My car has done about 63,000kms / 40,000miles.. clutch feels fine. Is the stock clutch setup not up to the task?

The clutch should hold like 7psi, but I would upgrade. My stock clutch had plenty of life on it when it came out, but the throw out bearing failed. I chose the Exedy Stage 1 clutch, which is the same as the stock clutch, but with a thicker/stronger pressure plate, and I am on a 85mm/12psi pulley with E85 holding fine so far. Upgrade the TOB to the new one with the dot, and upgrade the fork/pivot. You can do the snout too like I did if you have damage. Check my build.

Hello,
I wanted to ask,...Engine strength first or SC first?
Thank you!

I can't get E85 here. 98RON is the best we have. So I guess I'll stick with the standard pulley so maybe the standard clutch will be ok.

But yeah I did read your build which got me thinking about it. Just so happens I haven't done the valve spring recall yet, been putting it off. But it would make sense while the motor was out to get them to do some stuff. Although I am weary of these sorts of projects getting carried away cost wise..

New plugs. Maybe get them to clean the injectors??

@HachirocksU ...What's your goals? How much power do you want? E85 or pump gas? Depending on your goals, it may make sense to do FI then save for a build, but generally it is best to do a build first or save to do them at the same time.

@tzbang ...Yea, costs can build fast, but things are definitely cheaper when they are apart. Be sure to get a quote because they might charge you a computer calculated rate, regardless of how easy it would be to change the plugs with the engine already out. If the computer says the job takes 4.5 hours then they charge you for 4.5 hours, even if it takes 1 hour or 7 hours. I don't know about clean the injectors, but servicing the DI seals might be an option if you wanted them to make the motor tip top.

SC first. Built engine unnecessary unless you're trying to make crazy power.

Hello and thank you,
For California(SOCAL) option i'm limited with a tune w/o headers or go with a carb legal kit which I am content with those hp range. My goal is to improve as a driver and improve the tq dip on this car. I was also thinking about doing both at the same time as well but that could be hefty all of a sudden hehe.

Nope no crazy power for me. I probably wouldn't have to worry about rods as well yes? Is it an option for that piece of mind? Thank you.

Great to hear that you folks have re-involved with Harrop. It's nice that they keep the trd/stock airbox so it looks oem-ish.
Not ready yet but will give you folks a ring when it happens.

Install kit, throw on a safe tune, and call it a day. No need for rods.

Pulling the engine, opening it, doing rods, and then re-installing the engine will cost you more than the supercharger. Don't fall into the trap of unnecessary mods.

Invest it in a good oil cooler instead.

What he said is right. Just get a good tune on a base kit, and you will be fine. No need to build. There is risk with a rebuild too, and at that power level, the risk isn’t worth the reward.

PM when you're ready for the parts.

[tzbang]

Is an upgraded clutch, TOB, fork, snout and oil-cooler all recommended or considered necessary when going FI ?
