My old 95. 2wd. Trutrak locker , monster trans, 4 wheel disk brakes , STS turbo 8psi. 100 shot nos. ran awesome. Center mounted nos and boost gauge with monster tach. Turned heads goin down the road

where did you get a turbo for an astro van? I want one, is it TBI?

[JonnyAWD]

No it's a multi port Sts turbo has kits you put together. But if you look at how they do it you can craigslist or eBay a turbo and do it yourself for half the price

[markmitchinnh]

oh, well my van is TBI and I was just curious because in the past I was told that turboing a TBI engine is basically not worth that hassle to attempt

[JonnyAWD]

As long as you have an aluminum intake anything is possible. Easy 100 ponies

Sure, multiport FI would be better than TBI with or without a turbo, but...
Didnt the Cyclone / Typhoon 4.3 come turbocharged from factory , useing a TBI?
I believe it did, so I doubt it would be 'a waste of time' to turbo a TBI..

Did you open the ring gap for the turbo??.

[markmitchinnh]

the Cyclone / Typhoon 4.3 did not have TBI it had Multi-Port Fuel Injection similar to the corvette engines of the same era.

Well, you know, I've never seen one first hand, I only know what I've read, and of course we all know, dont believe "everything" you read on the internet.

That being said. I wish I knew positivly what to believe....
Wikipedia describes the type of intake manifold as an LB4 intake manifold with a TBI.
http://en.wikipedia.org/wiki/GMC_Typhoon
but
here is a link that shows it as multiport FI... http://www.cardomain.com/ride/825685/1993-gmc-typhoon/ the photo below shows what is clearly not an LB4 manifold.


JohnyAWD, have you got any pix of the engine bay or the turbo setup?
We would all love to see those!

[markmitchinnh]

That my friend would be a very cool addition to an Astro /Safari van though wouldn't it! we could call it the astro/syclone lol

[doyoulikeithere]

Yes it sure would!! (drooling)
We could call it a Safoon, or a Tystro or an abortion, Lol...
I suspect that the OP used a stock 1993-95 VIN W CPI manifold and modified it.
Hopefully, he can either confirm or deny that and maybe even show us pix .....
Wouldnt that be nice eh?

[JonnyAWD]

Like I stated. STS turbo. These are rear mounted under the van in exchange of your muffler. Check them out. Sts turbos yahoo or google. I'll put up pics later
