Title: Turbo nearly fitted
Post by: a on September 29, 2019, 20:29
Bought as a kit from Rayn2016 on here 10 months ago.
After sorting through all the bits (50% is crap).
Getting there though.

Nice to see a project coming along nicely, interesting place for airbox.
Keep the updates coming

Yes wanted to use the original airbox at this stage and that's
the only place it would fit,with a slight mod.

Ahh Apexi PFC, would be interesting to compare maps, base, ign, vvti etc and full specs of injectors, boost levels.

A word of caution.
TTE strongly warns against ány obstructing of the side vent entries when fitting a turbo.
Also that a heat shield above the turbo/exhaust is essential.
A fan with thermostat under the engine lid seems to be a must.

Plenty of cars run without heat shields no worries.

My aftermarket fan caused as many issues as it cured.

Although intake and engine bay temps did make me rule out a turbo for the V6 opting instead for the rotrex.

AH well, Toyota seems to have a fetish about them in our Spyder....

Good point. Can imagine that.

The battery would be obstructing the side vent if that's what you mean? Plenty
of gaps for the air still to flow.

I have two 180mm fans ready to be installed if needed just need to source a thermostatic switch.

Just driven it down the street, appears to pull well and the AFR is between 11 and idle at 15.

Happy so far

First things first; even for someone wíth a clue at the start you seem to made a really neat install.

I thought the OEM box (véry clever to use that) was sitting on the battery´s place and it is bulkier.
The proof of the cooling is in the driving though :-)
Good to read you are prepared if that pudding gets a bit too hot.

Chapeau to you!

Aftermarket fans what are the issues?

Making sure they don't melt for a start.
Getting them setup right.
So they don't spend all they're time on.

Cheers scotte. So a thermostatic switch/controller would be ideal?

If ever there was an illustration of the heat the exhaust side radiates....

Lóve it.

It is rather hard to get the mind around it: That, as Dev so neatly explained, the engine runs relatively cool in comparison with front engine cars whereas the exhaust runs a lot hótter, making for a rather complicated temperature management in the engine room.
