Title: T78... or GT4088... comparison?
Post by: milloman on February 21, 2008, 04:29:50 PM
Hello all, seeking opinions or knowledge/experience here...
 
Just wondering and doing a bit of a comparison - The Greddy T78, and the Garett GT4088... would anyone be able to advise either way on which may have pro\'s over the other one(and cons?)?
 
I understand the T78 is slightly larger than the GT4088... but that\'s all i\'ve ever hear about comparing the two so any info and opinions would be great!!
 
Cheers!!

Best bet is to do a search for previous discussions on each of these turbos.

Also a good source of info in the single turbo and A-spec Topics on //www.rx7club.com

i have a t78 on my fd m8 and i think its a very good turbo, not too laggy for its size and you can get quite a bit of serious power out of it...boosts full chat at around 4500k, but its still not too dead before that either :D

Interesting point actually, how comes? That\'s useful to know! (i\'ve got T78 on the rex that i\'ll be collecting in a weeks time, fortunately only done a few hundred miles so its still brand new!) My mate is also looking to but a single turbo\'ed rex and were wondering how to two turbo\'s compare.
 
Also, shaunwil good point on that one, rx7club has some good coverage - what wit the performance car scene being so much more alive than it is in the UK (that sucks :reallymad )
 
good comments so far! cheers!

Half of it is the price of petrol that kills it over here. Plus the yanks seem to get their hands more dirty !

What size footprint is the turbo ? Would have add A-spec 500R to the list, slightly smaller that the 4088 but is supposed to spool very quick. It has a T4 footprint.

I would have thought the T78 is an older turbo so possibly the bits are harder to come by.
