Holset turbos and the 3400 (Forcedfirebird?)

I want an engine that stays together and running

Zing!

Just be aware that the hotside is ridiculously huge. Know how big and bulky the cold side is on a bigger holset? The hotside is BIGGER. The HE351VE I had weighed 54 lbs.

HX35/40 might weigh a bit less/more but I am sure its ballpark.

Funny, combined my two have over 300k miles without major issues

Good luck using that turbo effectively and efficiently with a manual

Can you explain this better? What amount of boost were you running? What did you modify on your HX35?

I doubt the HX35 weighs 60lbs. I have had the VE turbos in my hand and they are considerably heavier than the static vein turbos. I know people repeat stuff they read on forums, but I have actually held these things in my hand, AND installed them on engines...

One second search on Google, 27lb...

I will weigh one to be sure, there are 2 at my shop.

I find it amusing when people talk about miles on vehicles/engines. I just sold a car with 360k on the clock and that's where the odo stopped 3yrs ago!

Have I got this setup right?

The boost that I ran that used a stock hx35, 93 octane not too aggressive timing 3" exhaust, stock converter was 20lbs. I found boost did not start to show up until after 3k.
That's what you seem to want to do and that'll be how it turns out. But the manual will not allow you to spool up when you're in the turns or trying to play at low speeds with a stock geared manual trans.

I feel Bridgetown might like the t04e variety better. Not as much power potential, but hits like a ton of bricks on a 3400/3500 hybrid.

Ok, now I see what you are trying to say. I may have to look into something differnt then if what you are saying is true. I'm not going to swap in an auto, so a different form of boost will be needed.

What about using two small turbos? Like off of a 2.0 vw or something like that? Those seem to be pretty cheap. What kind of characteristics would that produce on a 3400?

I spent alot of time thinking about twins, and I wouldn't do it, there's just no reason to. it's twice as much work in just about every aspect.

Two small twins would tend to spool up a bit quicker than a larger single turbo, but to me that small improvement is not worth all of the added complexity. For a quick spooling setup, the GT3582R or GTX3576R would be a good fit. If you want something reasonably priced, there are some awesome Borg Warner turbos out there. The S300 SX FMW is around the same size as a GT35R, but half the price and doesn't require water lines. I have a T04e 60 trim on my DOHC, but I would not go that way again. There are too many modern turbos that will dramatically outperform it for similar prices.

I should really post some pictures soon. I have that 60 trim T04E, a GT3076R, Borg Warner S300SX FMW, and T04Z (ball bearing 67mm Garrett compressor with P trim turbine wheel) all sitting in my garage.

Any for sale perhaps?
