Guest Rsand85 Posted April 13, 2012 Share Posted April 13, 2012 quick question folks as im struggling to find a TT block to start an engine build would an n/a block do as a starting point for a decent single turbo engine??cheers Quote Link to comment Share on other sites More sharing options...
l33wgn Posted April 13, 2012 Share Posted April 13, 2012 im no expert but from what ive read on here over the last 2 years your better off finding a tt engine, have you tried keron? Quote Link to comment Share on other sites More sharing options...
tony tt Posted April 13, 2012 Share Posted April 13, 2012 Go with the TT mate. As above try Keron. Quote Link to comment Share on other sites More sharing options...

Guest Rsand85 Posted April 13, 2012 Share Posted April 13, 2012 tried already no joy .take it the blocks are different then? Quote Link to comment Share on other sites More sharing options...
Dan_Turism0 Posted April 13, 2012 Share Posted April 13, 2012 only difference in the bottom end is the lack of oil squirters in the GE's and the pistons are different apart from that the rods and crank are the same as the TT engine. I'm going to be rebuilding my GE bottom end with ACL bearings ARP Studs and JE 86.5mm Pistons and Eagle rods this will easily be good for upwards of 800hp.

Dan_Turism0 Posted April 13, 2012 Share Posted April 13, 2012 why are you going to use an aftermarket crank? Are you going stroker then? Quote Link to comment Share on other sites More sharing options...

dr_jekyll Posted April 13, 2012 Share Posted April 13, 2012 (edited) why anybody would spend big money on a tt block to strip and build is beond me . if you want to buy an engine you never intend to open and you want to run a fair amount of boost then yes, buy a gte block. but the block itself is the same. there are variations in castings between blocks in ge and gte form but the fundimentals are the same. in the engine codes the 2jz is the block , the gte and ge specifies the difference in the head. now you can buy a bare na block for say £50 or a bare gte block for circa £800. buy buying the gte block you are basicly paying someone £750 of your hard earned and heavily taxed to drill and tap 6 holes. because thats the only difference. people talk of an extra water way on the manifold side for extra cooling but this water way exist in the head, not the block im sure sure if you have the required skill to fully build an engine, drilling and taping 6 holes in a pre set cast oil way should be a walk in the park , and even if you cant do that, any good engineering workshop will sort it with no issue. so my sumarry; if you inteld to buld a short block from scratch and you fork out big money for a a 2jz block from a gte you are ; A. too ritch to care B. crazy c. stupid. that is all Edited April 13, 2012 by dr_jekyll (see edit history) Quote Link to comment Share on other sites More sharing options...

V8KILR Posted April 14, 2012 Share Posted April 14, 2012 has anybody actually done this ?? I actually ended up feeding the oil squirter gallery from the outside as I had already drilled and tapped one of the blank plugs that normally feed to the twin turbos, as this is the same oil gallery. The feed is by an exterior oil line from the other side of the block and I also have a seperate one from the other side of the block for the turbo. I had to do it this way as I discovered the hard way that this oil gallery is dry after the engine was assembled and in the car. Quote Link to comment Share on other sites More sharing options...
