Questions about VW1302RSis ride

Hi Scott,
Sorry, I just pressumed u had a turbo version.
My water temps are excellent, well I think they are. In traffic, regardless of summer or winter the highest I've seen is 86d, then if I turn my thermo fans on I can drop it 10d in about 5 minutes. I was told that a thermo fan on both sides of my radiator , one pushing air, one sucking air wouldn't work as the fans would work negatively against each other. Not true.
Fast driving on the Freeway which is everytime I drive to the track as I have to leave before the sun comes up it just sits on 80d without the fans on, in summer it sits on about 84d sitting on about 80mph.
On the track, which was one of my biggest concerns about the conversion my water tamp won't go over 90d with the fans on & my oil temp has only got as far as 85d with no external oil cooler & thats in 35d Aussie summer heat, 5 x 2 minute laps at a time on boost the whole time. Oil pressure is 80psi plus all year round. I also have 2 radiators for the intercooler, one 300 x 300mm one next to the gearbox, the other a 600 x 300mm alloy one sitting in front of the radiator with it's own 9 inch thermo fan & water spray for the track to lower inlet temps.
I was given the advice not to use a thermostate by someone who does conversions for a living but I also checked with my engine builder as well before doing so. My 2 mates that did their conversions at the same time are also not running thermostates either with no ill effects. It seems to make sense to me, but then alot of weird stuff does
I'm just about to crack 30,000klms with my conversion & i've driven it through snow, flogged it on the track in summer & winter & also driven it though 30cm of flood water, whilst still taking the kids to school in the morning & getting close to 38mpg. It's working a treat.
On another note, I also use 15/40 weight oil on the street & 20/50 on the track, contrary to popular beleif suby engines don't like thin oil, especially for the track, thats how they do big end bearings which is quite common.

Have u had your car on the dyno yet Scott, would be interesting to see what the twin cam 2.5 puts out at the wheels.

With out trying to sound like a know it all prick I hope you didn't pay for that advise.

But seeing as I don't know everything (as my wife points out) I decided to ask a few professionals,
So I called a service manager of a Toyota dealership I know who is an A grade mechanic with over 40 years in the trade and playing with race cars, and he agreed with me but gave me some grief for asking him a question I knew the answer for. But as we both could be wrong I wanted to confirm so I wanted to asked a 3rd party. So I left the warmth of my office and went down to the workshop and asked some of the qualified mechanics there what they thought and they agreed with me, but I thought they would.

We just can’t see any reason why you wouldn’t run a thermostat, unless it was to overcome some other problem?

Yes I have had my car on the dyno it’s a EJ25 SOHC not a DOHC and as I don’t like talking about power figures as it always end up sounding like fishing story’s, and it depends on the dyno and the correction methods used, sae, din, temp correction bla bla bla.
It has enough for the moment.

Like I said Scott, 30'000k on the conversion, driven daily & flogged on the track with Porsches. if it aint broken, don't fix it.
Each to their own.
Just can't understand why u would ask your local toyota dealership advice about a wrx engine in the back of a 71 beetle?
Good luck with yours.

Fair comment Jak if it isn’t broke don’t fix it.

It wasn’t the Toyota dealership I was asking, it was the man at the dealership I was asking, he’s raced every thing from Karts to Sprint cars including an old F1 Cooper Climax and a Subaru Speedway Saloon.

But hell all I was saying was I don’t understand why you wouldn’t fit one, that’s not knocking your car or how well it goes, I’ve heard lots and lots of good things about how well you car goes on the track and 30000 Ks speak for it’s self

No disrespect for you or your car, I guess I was just knocking the man who recommended you ran with out one.

Thanks for that Phil

I’m sure every body on this board wanted to know my history, well your inaccurate version anyway. How about you remove this post, I’ve pissed Jak off enough with out you helping.

Jak, sorry about Phil’s comments, he can’t help it he was born in Naenae, the biggest ghetto in Wellington and his mum didn’t love him.

Man, I envy you Super guys for the space you have up front

Scott, do you happen to have a pic or schematic of all the breather hoses ?
How did you hook al those up ? Especially the connections to the left of the throttle body ? I think these are the crankcase ventilation ?

See pic (Arrow 1 and 2).


Also how did you mount the MAF / air intake plumbing ?


Thanks!

Rob.
