yes and its cast mani too.

 

Hi , and how spool it ?I am interested in buying Hta37R as replacing my regular GT35R , but I have doubts respect spooling . I build a 2.3 , HKS 272 , GT35r , and head full ported and flowed by myself for drag races of 250 mts (0.155 miles) , 503@6600 awHp and 488@4700 awTq on DynoMite , but GT35r are too small for engine and 93 octane gas .

 

5K rpm
When it passes 5K rpm you got to hold on tight!

 

i think on 2.3 it might give a beter spool .lets see wat hapens

 

heres pic of mine

 

not bad

 

What was the dyno calibrated at'? 9%?
You are not going to get probs with the meth inj you are running .
Just put some better cams and Fmic ( if you are still with the old one) you will find near 80-100whp if is do it right.

hey ,just recieved my t4z 88hta turbo and ams vsr .looks gr8 ...lets see how it performs ...

 

My friend made 460 (dynodynamics) on a AMS HTA 37R, AMS race head, Tomei 280's, AMS 2.3RR, etc. on 27psi. Incredibly good spool, but the head probably has a lot to do with that.

 

rnt these a bit low numbers as per the specs of the car ?

 

Do you have a dyno sheet of your friends dyno run? Where do you think he got full boost at?

 

+1 on this .....

 

IM guessing just 91 Octane, no meth....in reno.
