and im missing a throtle body

custom 4-2-1 race header
flow master mufler with a strait thru no cat.

my question is what throtle body should i use a 68mm or a 70 since thats all im missing and will i have a problem with clerance since the cams are real big. plus have any body use the secondary injector on the performer x a lil info abouit them would be nice. thx and fell free to coment good or bad.

 

that is a very iffy piston choice, i hopw you know what your oding with that. your cr will be almost 13, although i see you kind of balanced that out with the pro 3's, which is a giant cam.

look into the new professional products tb's i just got mine it look really nice. 70mm taperd to 68. port match that to whatever manifold you have and it should be a ncie combo.

what do u meen by 70mm taperd to 68.

 

the opening at the intake side is 70mm and follows a factory 2mm taper down to 68mm at the manifold side to help with throttle response.

 

professional products tb's almost oem

 

pro3 on stock bore stroke b18? wow...

 

probably th eonly way he will balance out the cr given by the pct's

 

Yeah but what about P2V contact?

i was looking for 13.1 compretion so i coud move the cams but them i ran in to p2v problems so i got the cosmetic head gasket 4 a little more clerance. . the motor is going to be tune on 110 octane this way i dont lose power retarding the time .

 

its not the point that your gonna need to tune it on 110 is the point that you cant drive the car on anything but.

 

if its going to be a daily driver you have no choice but to use 110 or else your goign to be pinging liek crazy. i think p30's would have been a bettrr piston choice since they weigh less, have better flame travel and they yield around 11-5 11-7 CR depending on what head and gasket combo just my .02

the car is going to be a weakend car so 110 is no problem.
does any body have any sujestion about 68 or 70mm throtle body, im thinking about skunk2

 

or get the one i mentioned for 130... and not have to worry about it sticking.

can i buy this one online (what web site ) or can i just go to like full throtle and get it.

 

i would say if you must have 13:1 comp, tune it on e85 if its avalible.its like 2.90 per gallon and is the equivilent to around 105 octane or so. i would say a pro3 is to large for a 1.8L motor. a pro2 would probly work better.

thats what alot of people is telling me but i already purchase the cams and cant returned them so i figure i should give them a shot and if it dont work ill buy a b20 block and tranfer everithing over.

im just dyen to finish it and just drive it. its been a long time.

 

Sounds like a nice setup. Wish I could help you out but goodluck with the build.

i have a bad feeling it will not last very long due to some piston to valve contact unfortunatley.

the tb can be had at vsracing.net or kteller sells them also.
