I'm sure I'm going to be blasted for this but I'm just curious at what are some of the diffrences between the VG30DE and the VG30DETT that would prevent you from just bolting on exhaust manifold and a couple of TT? If someone could take a couple minuets to explain it would be vary helpfull. I know that the VG30DE has a compression of 8.5:1. Which should be good enough for turbo's.

LOL No, you don't know.

VG30DETT's have 8.5:1 compression, VG30DE's are 10.5:1. You absolutely cannot bolt turbos onto a VG30DE.

Search... every NA owner has asked this question at some point in time. Easiest way to turbo an NA is an engine swap.

 

Thanks for clearing that up for me! Got to start somewhere!

i thought the DE was a 10.5:1 not 11.5

 

yup^^. pretty good read for the first few pages. you aren't supposed to do this, but honestly, another good read on it is on www.3zc.com tittled "fast N/A's?". i know it will answer the questions that you'll have next.

edit: not yup^^ snw, yup^^ nismo

 

oops

Yes, 10.5:1... still too high for FI.

I really must be slipping my old age.

 

What about swapping TT internals into an N/A block?

 

Why? Because you want to do excess work for no reason?

The blocks are the same, but that still neglects the fact that the heads are different, plenums are different, etc.

Again I am forced to repeat myself... a flat out swap is the easiest way.

 

10.5 isnt to high if your a crazy engine builder but in this instance much to high.

 

methanol injection ftw

 

how big is the improvement with that on a N/A? i could look it up, but you mentioned it

 

he was saying 10.5:1 with a turbo needs methanol injection to attempt any real boost at. he was building onto my statement. lol. on an NA it would be pointless

 

oh oh. yeah i missed that he was building on your statement. got it;.
