Hi all,

So it's time to start my own build thread, after dreaming about it for the last few years. okay, my intension for building this car isn't for track use. I wanted a weekend warrior/Dyno monster something like that.

I need your input on the parts, what I need, and what to look for next in-terms of changes or addition.

Here we go... So I picked up a fully built engine from here "market place" it had 0 miles on it, which somehow was good for me.

on to the engine specs:
CP 8.8:1 pistons
Carillo Rods
all new ACL RACE bearings
1mm oversize Supertech valves (and springs)
3angle valve job
New valve guides/seals
Scott's Performance Cams Stage 2 255/255 213/213 .410"/.410"
HR head gasket
HR head bolts

externals:
Momentum headers and turbo kit gt35r " I may go with a bigger turbo gt3794r or gt40r ????"
kinetix plenum
full fuel system "rails, regulator, return line, etc..."
bocsh 1000cc injectors.
welbro 255 pump

EMS:
I will be running UPREV for a while to save up for a Haltech or proEFI128.

drivetrain:
DXD-F stage 5 Southbend clutch
JWT flywheel
VLSD

so lets see how it goes.....

 

If you going with the momentum ST you will have a fun time making the 37r fit and forget about 40r. If you don't have the turbo kit yet, a much better option is the boosted performance kit.
What's your power goal?? With the bp kit you can hit 700whp with a better fuel pump.

 

^+1. If you want a dyno monster, the BP kit has a much larger turbo option.

 

jtgli used the kinetics plenum (vers 2) and blew the welds open at high boost. You may want to try another option.

The +1mm valve may also be a waste of money. I got similar flow to HR heads by just having some blending done.

 

like others have said, a quick search will show you your turbo kit choice is a poor match for your motor.

you dont want a walbro either. You want the newer aeromotive 340lph or DW 300 pump.

If you are running uprev, you also need a boost controller, like eboost2 or EVC6

 

Walbro 400 will work fine, not too much work to make it fit

 

Will it might be too late to go back on the turbo kit since I have bought it a year ago.
Bp kits are awesome but for the time being I might just stay with what I have.
as for the fuel pump yes sir had that in mind I was thinking with injectors this big I will out flow the pump so the DW is listed.
as for the boost controller since I'm running uprev I went ahead and ordered a Greddy Profec B Spec II.
Cosworth plenum is a great choice but right now I'm way over the limit so I might include it as a next step with water/meth injection.
What do you guys think about water/meth??? should I do it or stay with pump gas tune?

 

bacpressure is going to be your limiter. wouldnt spend money on a meth setup.

 

will since I had a limited idea of what the hell am I doing...
I started reading about exhaust back pressure. what I have
assumed from that is buy going with bigger up-pipe/hot side plumbing
I might get away with it ??? Correct me if I'm wrong... by the way this
is the first boosted car I have ever built, so I have a very limited knowledge
about the boosting world, but anyway I'm trying to learn...

and please excuse my typo since I'm not a native speaker...I'm trying my best lol

 

Problem is there is no bigger hot side plumbing for that kit, also the T3 housing of the turbine will be super restrictive , if it was a T4 it would be much better

 

the restriction is at the turbine housing. since you already have the v-band housing, thats as big as you can go. You will still make around 500whp which is more than enough for alot of fun.

 

Meth is a great option. Especially if you are limited in octane locally and e85 isn't available in your area. It won't give you a ton of hp, but at least an extra 30hp and added detonation prevention is always welcome in my book

I'm going to run it, but go with a good kit. I bought a perrin kit from a member on here without thinking much about it and now as the build is coming together I'm regretting the purchase and wish I bought a better kit.

I'd recommend spending a lot if you actually want it to "make a difference". Go for either a devils own or aem... make sure it has a flow gauge and all the safety tidbits so you don't have to worry about low pressure/low fluid levels etc.

That being said, go for a boosted performance turbo kit instead of a momentum single. BP kit will make much more power.

 

Meth is great until you run dry on an over aggressive map. You're probably a good candidate for it though since you're not tracking the car.

I'd consider taking that momentum kit if you want to go with boosted...given it's new and not used.

 

If your talking about the factory lsd then you'll prob want to save up for an aftermarket alternative.

 

why? (the stock VLSD has gone into the 9s and he's not tracking it)

You also don't want a walbro 400 if you're limited to 500 whp anyway - all you'll be doing is flowing tons of fuel at idle making it nice and hot... As str8dum1 stated, the dw300 is a good drop-in option right now - with full e85 compatibility, 3 yr warranty, and quiet turbine style pump it will outflow and likely outlast the walbro 255.

 

good... so AEM meth kit including gauge and everything, DW300 are listed as then next
step after breaking in the engine. ok... I might need your help on this...
how about running custom hot side " I will get a shop to do it"
I have no idea if it's possible or not... I think one of the restrictions would be
routing style of it, if not then it's worth trying don't you guys think soo....???
about the VLSD I have seen a lot of cars that are being tracked with the vlsd
and upgraded axles... thing last for ever.... if you don't beet on it like sh*t

 

If I were you I'd look at better headgaskets and l19 headstuds. With those rods and pistons you can go to the limits of the stock sleeves without issue (should the motor be put together correctly).

 

Like str8dum said , your biggest restriction will be the turbine housing , you would need a new turbo like a 6766 T4 turbine housing. That means modifying your up and down pipe, and still it might not fit

 

will fist, lets see what I get out of the kit it self with the gt35.
figure out the next step. I might modify the kit to try and make
the GTX4294R with the tail ss 1.15 a/r v-band housing fit
if possible I will talk to my shop and see what options I have
regarding the fitment.

 

Maybe I missed it, but how much power are you looking to make? It seems like that answer will dictate all the other things you will need. There is a lot of talk about modifying stuff, and restrictions, but if you only want 475hp, well it is all a moot point IMO.

If you are looking to go into the 6, 7, 800 hp range I think you may need to rethink your plans.
