RSKB4 from NZ

  Top of Page

Hi All,
I have a white 99 b4 thats going through some r&d atm, i bought the car in september last year and im in the process of building my 3rd 2.5 engine, the first one broke 2 pistons and ran a bearing and the second time a valve broke and destroyed a cylinder head, one piston, twisted one rod and cracked the block. This time im using an 8 bolt 2.5 block, standard rods with 2.5 b4 pistons, ive ported the exhaust control valve and fitted larger exhaust housings to both turbos. I also have sti brake hoses and pads, tein coil overs, mines lower braces f&r, symms strut brace and exhast manifold yet to fit.

Its not as bad as some might think, if I was paying someone to do all the work I might have given up by now but I want to prove that you don't have to convert to single turbo to get lots of power.

I changed my primary turbo exhaust housing to a vf13 which has an a/r 16 and my secondary exhaust housing to a vf19 a/r 18, my vf 27 secondary had an a/r of 18 also but the vf19 runs a larger turbine wheel so the housing is bigger. The easiest way to tell the difference between the housings is to measure the width of the scroll at its highest point. These were the largest housings I had spare. You can only swap the housings within the twin turbo vf range but i don't think you can go smaller in housing sizes only larger.

Hey welcome big_smile

i think ive got a twin over there. good to see someone playiong with the TT.
im building a full forged 2.2 and some goody bits in secret coming.

what 1/4 mile time or KW atw have you achieved with the 2.5?
i would have thought the tts would still run out of puff on a 2.5 in the topend even with bigger A/R

I haven't had my car on the track or dyno yet but once its run in I will be interested to know what it can do. The turbos don't seem to run out off flow top end to my suprise and the car pulls all the way to redline in 5th gear without slowing down.

Yes we NEED PICS!!!!

Heehee. Sounds like your a nutter, i've rebuilt mine twice aswell. Keen to see some pics.

How hard is it to do the swap with the turbo's!!! Mine run outta puff with a 2.2, but they are stock turbos. Im supposidly getting mine tuned on wednesday so it will be good to see if a good tune will make it run better.

But i want more power and was considering going a single conversion, but if you are getting 200 + kw atw with those turbos then maybe it might be cheaper to do it your way!!!!

Have you tried running the tubo's in a parrallel setup...... thats what im thinking of doing..... taking the ic flap out and see how she goes... easier to tune tooo!!!!

The exhaust housings are easy to swap over its just taking the turbos off thats the difficult part. You might also need to get some gas on them to seperate the housing from the core  but I just use an electric heat gun.  I won't guess how much power im making yet i'd rather wait till its been on a dyno. It feels like the second turbo comes on boost around 3k rpm so im not keen to change the exhaust manifold yet, after a bit more development I will get my symms extractors  ceramic coated and heat wrapped and find a matching pair of exhaust housings to run them.

Its called r&d, nobody gets things right first time. My first engine cracked two pistons and on the second engine with later model pistons a valve broke while being run in and destroyed the engine. I know how to bulid engines and I can get parts cheaper than most people. It costs me alot of time not alot of money.
