Engine Build

[Toadie's T-Type]

Ok. Here Goes. I'm looking to build my first Turbo V-6
The engine I have now runs good. But. I want more power.
I talked with John Craig via e-mail on a suitible turbo to acheive what I want performance wise. mid 11's and streetability.
He recommended either a TE-61 or a 62.
He also made mention of a Precision intercooler as a recommendation as well.

List of parts I have to build with so far:
Walbro 340, Adjustable Billet FP Regulator, 57 lb Injectors, LS1 MAF, various new sensors. Mini Starter,

Now for the Questions....
I am thinking of building it from a 4.1 Block.
What year of 4.1's are suitible for the turbo build up?
Brand of Pistons?
A good cam recommendation for both roller and Hyd.?
Timing set. Steel Tooth Double Roller? Nylon stocker?
Heads. Stock with what size of valves?
Aluminum with what size of valves?
Roller Rockers? Tbs rocker set?
Stock intake good enough?
RJC Plate???
Upper plenum recommendation? Hempco, ATR......
62. 65. 70 mm throttle body?
Jay Jackson Treatment. Yes or No?
Headers. What are some of the best out there?
Cold air intake system?
Translator or Translator Plus?
Good Alchy system.
Turbo pre luber?
Oil Pump. High volume or high pressure or High volume/pressure?
I'm pretty sure I'll go with a Jim Testa chip.

I'm sure I missed something. If I did. I'll add it when I think of it.

These are questions I ask that someone will probably throw in a link and say go here (gnttype.org) But. There are many new parts out there that the recipe section probably doesn't have listed yet.
I want recommendations based on what the community here sees as working parts/combinations.

Thankyou. -Matt-

gnttype.org recomends sticking with the 3.8 109 block if you have a good one. 4.1's are real tempting though, I've thought about it. gnttype has a good write up on 4.1's

definatley get the RJC plate.its great.really no need for aftermarket headers till u get in the 10's.and i heard the translator plus is better w/a MaxEffort chip or some kinda of thumbwheel chip

If you mtr runs good now ,no need to rebuild .
Add TE-61 turbo
42lb or larger inj's
PTE frt mnt IC
THDP
Nice 2800 stall D5 conv
340 fp
chip of your choice
race gas
slicks
25 psi boost or more
scan tool
fp gauge
Valve springs 90 to 110 seat presure
good timing set (TA set )
9" kn air filter
engine tie down strap
boost gauge 30 psi
RJC plate

No need for translator if your stock mass air meter is good , no need for headers , larger T body ,ported heads or intake,stick with the 3.8 109 block if it is good , no need for aftermarket cam as the stocker will work well , stock oil pump is fine , pre luber is not needed .

cars in my area run mid to low 11's with above combo

from all the stuff that you listed above to run in the 11s range,I would listen to him.Good advise.

[Steve Wood]

Other than the too stiff valve springs, IMO, and the tie down strap, the combo should be a good one.

I would stay at 85# or less on the springs, and use a poly ds engine mount in lieu of the strap.

Hank's Limited with less stuff. Check out his GN that runs 10.95 on a 60. Go find UNGN's page with his mid 11s similar to Hank's Limited. Or TurboDave's car....

YOu don't need a bunch of stuff...you need a healthy engine with no worn cam lobes and good compression...the rest is simply combo. A well burned chip, or a programmable one such as the ME makes it easy. All this magic stuff is not required.

I had contemplated on doing a complete build up since I had bought the car from my brother and it had seen NAAAAAWS.
I took it all off when I got it.
The 4.1 was mentioned because. If I need to rebuild it completely. I wanted the extra few Cubes to play with.

I did forget that my brother had swapped out the cam that was in this engine (Which someone else had swapped out the stocker for a different one. That guy's name is George Hall)

My car currently has a cam from Poston's.
GN110T Lobe Center 110 AD I/E 266/258 D@.050 I/E 212/206 Valve Lift I/E 478/456

Also. It has a 3 or 5 disc Vigilante 9.5" Converter Can't remember right off the bat.

I forgot about the Valve springs. I have a set of C.C. 980s. I was gonna use them on my small block Chevy. But the cam I have in the motor called for different springs.

I can take the above replies from everybody into consideration.
I wanna hear more from you all on this issue.
Except from those people who have there cars decorated for the holidays with them parked on blocks. Thier knowledge of turbo cars are null and void.

Hey, Zap knows some Sh**!

** A FMIC is "bling-bling" in a mid-11s scenario...use that $$ elsewhere.

** www.turbotweak.com for a chip and thumbwheel, specifically made for your combo.

** Hi-Z 57# injectors will provide the best duty-cycle safety margin without going to a modded ECM.
