turbo size question
I was given a holset H1E and want to try to use it on my FD. I contacted the manufactur for the specs but cant figure out how to convert what he sent me to something I fully understand, Hopefully someone can be of some help. I can tell by looking at it that the turbine housing is going to be a bit big, but I dont really care at this point. Its just a temp turbo to get the single project of the ground and it was FREE. Eventually i'll get a gt40r 1.06.
Compressor A/R- .6 cm^2/cm
Turbine A/R - 3.42 cm^2/cm
Thanks

You have a nice turbo and I will work just fine. Here is link to H1H vs. GT40R.

It sounds like what I got from holset is wrong. I'll post a couple pics after my camra charges, probably wont help but we'll see. The serial number is 3526368 if that helps.

Compressor wheel size = inducer 59.93 / exducer 81.66 I think it was about 50 trim but I forgot the equation to figure it out.
Turbine size = inducer 75.55 / exducer 66.95
1.34 wow... alittle big. My motors a "very large" street port but still. Maybe I'll try to get a hold of something around 1.0 to 1.15.

here is some information I have collected about Holset hotsides (I cannot 100% guarantee accuracy)
Holset housing size - Garrett approximate equivalent
9cm^2 - .48 A/R
12cm^2 - .63 A/R
16cm^2 - .83 A/R
18cm^2 - 1.00 A/R
22cm^2 - 1.15 A/R

arghx,
So what housing A/R do you think I have here. Its obviously pretty large. Hopefully its the 1 or 1.15. Its a 3.5 in v-band if that helps...
