the standard gt35r is a gt35 dbb turbine with a gt42 compressor in a 0.7 ar housing. it's also widely known as a gt35/42.

 

 

You sure you dont mean the standard GT35R is the GT3582R being an 82mm exducer?

The stock GT35R wheel is a 71 or 82mm exducer, GT40R is an 82 or 88mm exducer, GT42R is a 94 or 102mm exducer ( edited, these are compressor side)

 

If you have a comp wheel from a GT40 that has a 82mm exducer, the inducer is 58mm, so actually smaller than the regular GT3582R

when i was looking for a replacement for my broken comp wheel a few places said that it was the same wheel as the gt40 (inc garrett), which it is. the 82mm wheel that is in the gt40 is available in 2 trims (IIRC) 56 and 52, the gt35r uses the same wheel, it's not a new wheel for that turbo.

Correct the Gt40 has an 82 mm and 88mm exducer. But the inducers are 58mm and 64.7mm respectively.

 

So you can see the confussion as the specs you mention above fall bang on for a total stock gt35 set up ( not a replaced wheel) Unless some machining went on .

 

 

Here are the specs for you. http://www.turbobygarrett.com/turbobygarrett/products/turbochargers.html

 

Its all good banter , but a good all round learning for us all.

In a first for a thread started by Jake Im moving this from Supra Chat to technical
Bloody cheek! :D
I personally would have preferred to go up a size of turbo, I like the kick in the arse when a turbo comes on line and thats not quite as present on a 61 as I would like.

Might that be because you're on the more restrictive budget manifold/adapter? I presume you've had it properly mapped by now, right?

LOL

 

It was never mapped properly, and now Im about to get an emanage Blue fitted so will wait until thats in and then take it up to Ian C for mapping.

 

It does prove you can run 1.2 bar on stock 550cc injectors running the stock SAFCII map, ran it like that for the last year and a half.

Thats the people. Did my downpipe and a 2nd decat "while I was there" ;)

 

Yeah, I think I'll be paying them a visit too for a 3" 2nd decat pipe and possibly to do the slight tweak to Arnouts pipeworks kit that seems to be needed. One of these days I must learn how to weld...:think:

what you doing for ECU?
I still haven't decided. AEM or eMU are the favorites at the moment. I can't be spending 3k on an ECU and mapping. The eMU would be about a grand inc mapping, the AEM is about 1k for the unit but maybe somebody has already got a similar setup (GT35R, PE650s, Auto) that I can get a reasonable base map from and adjust it from there myself. Dunno really.

 

Eyefi, what fuel management/ECU are you using mate?
