Thinking of doing my own uppipe.What inner diameter and material thickness do you recommend ?
Thanks !

you will need to provide a full spec of turbo, engine, headers ect but personally for the sake of £139 you can get one of harvey's trick pipes already wrapped and flowed to your spec

Engine : EJ20G Closed Deck (1993 JDM WRX)
Turbo : Mitsubishi TD05-16G
Headers : Stock JDM WRX headers
139 pounds is a lot of money for a pipe o_O

I can provide VIN if needed...

£139 is not a lot of money at all, the up pipe is responsible for the spooling of the turbo so if you think saving a few will help you are wrong as it will most probs end up ruining the way your car spools and drives, i think the id is 43mm for the tdo5.

With respect to the OP, perhaps Bulgarian wages with repect to goods' prices (esp UK goods/duty/import tax yada yada) isn't that great?

Just a thought...???

If that's not the case, then I agree with addi.

It really depends on the size turbo being used i.e. its air flow rate in CFM (cubic feet of air per minute), or lbs/min (pounds of air per minute)

As a pointer, I have a 20g turbo and I happen to have just bought Harvey's (on his recommendation) latest trick uppipe design for its matching GT1 tubular headers, and the entry is c.60mm dia.; the exit c.48mm. Plus it's slip jointed to prevent cracking. I believe a 20g typically flows IRO 38-40lb/min. (or 550-580 CFM)????

I'm getting the mapped tweaked for these items tomorrow.

Well,I guess I will have to buy one,as I don't want to ruin a good running car...
I'm shopping from the UK,because parts are more expensive here in Bulgaria...

Good decision.

Defo contact harvey... give him the list of your engine spec & suppoorting mods, and he will recommend the optimum uppipe for you (and headers if required)!

OK so you have a TD05 16G.
What headers are you using? Standard Subaru original equipment?
The uppipe I would supply you with would be stainless steel, slip jointed, purpose designed for your application with five new Subaru studs to connect to the turbo/brackets and DEI heat wrapped.
I do need to know what headers you are using because I would match the uppipe to your requirements but all the uppipes are purpose designed because obviously different uppipes are required for different applications. £139 plus delivery at cost.
