Maxing out 13g turbo.

[chanley talon]

Simple questions willa 7cm turbine housing from a 16g fit on a 13g turbo? Second what is the fastest time with a 13g . I want to max this thing completley out . I mean unhook the waste gate and let it give me its best shot. Dont worry i have all the supportting mods needed. I could max out a 16g turbo. But My 16g is blown and i have this 13g in great shape laying here for now. So i want to modify the crap out of it. A big housing will help it flow better. But will it fit ? Thanks

A 16g housing won't fit on a 13g because all the DSM 16gs use the TD05H turbine wheel and the 13g has a TD04. The wheel is much smaller on your turbo and won't work at all with a 7cm TD05H housing.

So the wheel will fit in but the turbine housing wont seal? Basically what dont meet together?

The TD05H turbine wheel would never fit inside the 13G's turbine housing. It's too big.

A 13G has a 5cm2 exhaust housing as well. There's no way it would push enough juice at 360cfm to fill that 7cm2 housing even if it did fit. It would be like porting a T25....your car would be slower.

If you're trying to kill it, just bolt the thing on your car and leave the wastegate unhooked. I don't even know if it will boost over 18psi but if it does, it won't for long!

Yep, won't fit. I ran a 13g back about 16 years ago. Sent it to Turbonetics and they put a 35 lb/min compressor wheel (Garret Super 60) into it and clipped the TD04 wheel 15*. Problem was the turbine housing. That housing and exhaust manifold could use a massive port job to open up the collector area, which was about the total size of a silver dollar if that. You could also actually port the turbine throat "very carefully" to open up the A/R a bit. Other than that, there isn't much more you can do to it.

That by far was the quickest spooling upgraded turbo I ever ran, something like 18 psi by 2600-2700rpm, maybe 260-280 h.p. Got that turbo in a box somewhere, would make a monsterous autox turbo. Makes a Big28 look like a 50 trim in terms of spoolup.

Now that's something you don't hear everyday

My brother had a 13g on his car. It was insanely fast through 1st and second. Full boost by 3k rpms. She loved to launch.

Really?

I wonder how a Td05 would work with a upgrade kinda like this...


And im not talking about those peice of shit frank turbos

 

[ThingyNess]

People do things like that all the time -- like making a TD05H-20g with a clipped turbine wheel, or as you say, the frank turbos, mutt turbos, or any number of other garrett/TD05H hybrids.

Just a little insite, when you reach around 25 lbs/min, you're done with this turbo. There will be no more so don't break it for no reason.

The compressor map shows 0.17 m^3/sec at 17.5 psi (sea level). This equates to 371cfm. . . And approximately 25 lbs/min. Nothing to write home about .

I know that, but ive never heard of somone doing that with a 13G

Seems like a really nice autoX setup with spool so fast like that, and a decent 280whp


I wouldnt run it, thats a very slow car to me but for auto Xing seems like a nice setup for people into that...


We should let the guys in the roadracing/auto X setup know about it

By far the coolest Frank turbo I've built to date was a 7-Fin GT30R compressor wheel shoe-horned into a Small 16G compressor cover. It made for one hell of a sleeper if you're competing in a stock-appearing class. I wanted to clip the turbine but we were on a time restraint as it was.

Here it is next to a standard Small 16G:

I did this mod when I knew nothing about DSM's back in 91-93 and I was still buying everything out of HKS's catalog and Turbonetics was the big turbo supplier at the time. There wasn't a Forced Performance and Dave Buschur was just starting to sell pressbent downpipes out of his house.

The spoolup is actually much quicker than a T25. My brother ran this modified turbo and a nicely ported 14b, and he always was begging me to slap that Turbonetics modified 13g turbo back on cause it hit much harder on the low end and midrange. Once you hit about 80 mph the tiny collector opening in the manifold would literally act as a speed limiter, the car just would not accelerate after that. This is what they would call choke flow these days. That turbo was begging for a massive port job on the manifold collector and turbine housing. Even the exhaust manifold had smaller diameter runners just like the current EVO's, another trick in helping spoolup.

I wonder how a 16G would respond to somthing like that
