So I want to run the GSP T3 cast manifold http://www.ebay.com/itm/291253217607?_t ... :MEBIDX:IT

..With the FP blanket http://www.ebay.com/itm/300715581521?_t ... :MEBIDX:IT

I'm basically looking for a budget set-up for my daily Colt 4g61T. Consisting of those 2 items and the T3 10cm 20g http://store.forcedperformance.net/PROD ... 04600.html

The only thing I don't like about the manifold is the single runner wastegate but I will likely stay internal and use that provision for an EGT or something. I know the 20g is old technology but I'm looking for mostly reliability with some decent power, 300+ wheel on the 1.6.

What do you guys think? Decent set-up? Should the blanket work? I will likely just get it coated if not.

Are you dead set on a 20g? I'd think with the 1.6, it would take forever to spool...

No, but I think it's a great price for a proven turbo. IMO the best way to make decent power on this little motor is to push some good airflow while being on a T3 housing to help lower back pressure pre turbo. The 1.6 should be ok with revving a little higher than the 2.0 too, that should make the lag less apparent or a little more tolerable.. I think.

I'd personally stick with a 16g of some with a port matched manifold/housing/02 housing. I just dont see the 20g in a t3 housing being very responsive on a 1.6l.

My opinion is different. I'd be OK with a 20g on the 1.6 but not with a 10cm2 housing, that will be a lag pig. Sure the 1.6 might be happier than a 2.0 at higher rpm but unless you're set to rev to 10,000rpm you're not using the rod ratio advantage. Personally I'd be OK with a 7cm2 20g. If you run short tires and maybe even an AWD tranny, the gear ratio is short enough to help keep revs up easier. Just my opinion though.

I hear you guys there and I agree. I guess I'm just curious about this set-up. If all fails then I'll just swap a 63 in where the 20g would do just fine. I may upgrade the valve train with some 272s and see what happens. I have HKS cam gears and JMF street manifold for it already too. Maybe I'll just end up seeing how much lag it takes to annoy me lol.

Haha. Nothing wrong with experimenting a little! If you do that setup I'd be happy to meet up and see if the lag annoyed me as well. Lol.

For sure! What turbo do you run and when do you see full boost in 3rd?

Small 16g, I can't say exact numbers off the top of my head but I'm sure it's around 36-3700rpm. The little 1.6 is way more laggy than a 2.0 but I think as long as a guy is willing to adjust their driving style it can be manageable.

What's the 'best' way to get a small 16g? They are insanely expensive new, yes?

What about a tdo5 20g? You know stock appeal but good room for power

^ Too similar to a evo3 16g IMO, I want to do something a little bigger, a little more risky. If I happen to find a great deal on a smaller turbo or something BB then of course I'll go that route but we shall see. From what I see a B16 makes good power boosted (reliability aside), but the 61t seems to lag behind that quite a bit. There's no reason the 61t shouldn't make good power. What is the record whp for the 61t anyways?

Are you looking for a fun daily or max power? That would be the better question. A fun daily requires quick spoolup. Admittedly, I enjoyed my (63'd) Colt more as a daily around town when it had the instant spool of the 14b. Sure it's faster now with the bigger turbo but it's all straight line.

On my Talon with the 2.0 I had no issues daily driving on a td06h 20g or a BB60-1. But a 1.6 is a different animal. I still don't think I'd have any issues daily driving up to a tdo5 20g on a 1.6, even despite the lag.

If you spend all day shifting at high RPM's, a fibrous sycnro early model 89 turbo or 90 DSM transmission, will not give you a long and happy life looking for gears in short order.

If however you change the transmission to a 91+ FWD or modded AWD with mods, you could have a syncro set worth writing about, and the capability to enter into EVO3 heavy gear sets and close ratios.

nodents made 286ish IIRC, and that car was plenty fast with some sticky 16" tires on Tiburon rims. EVO3 powered, very short route intercooler setup, etc etc.

I would focus on a motor component setup that is made to spool up fast and make great power, ala EVO3/DSM 7 bolt head/Cyclone with runner plug moulds to match 7 bolts + 4g61 style intake ports. We've all seen the similarities between the components, and even the pictures that came from Lanceman Jerry.

We used to have a member here called Mysterman. He never wanted to post his location, and even went so far as to delete ALL of his posts when he got spooked.

I learned however, that you could confidently run a 20G on a 4g61t, but my question is why.

The power band is too far up, too short, and is only good for short bursts. IMHO.

Focus on torque, long power band with balance and quick spool, coupled with a very streetable clutch/flywheel combo and suitable transmission modifications like new syncro's

and something a like an AWD Quaife ATB in the 91+ FWD DSM 25 spline transmission.

Yes, a KM210/F5M31 does have gearing that keeps the RPM's much higher, so there is that going for it when you want to shift high and repeatedly. Not my taste ...

Exercise the legs in the DSM trans, at is just feels most suited behind the 2.0L motor. Such has been my experience so far. I'm still getting the car through teething though, as

it is prepped for the fuel pump swap and subsequent AFPR and fuel mapping chip rework/install.

Those are my thoughts for what it is worth.

Spool, decent frame turbo setup, torque, gearing, differential treatment and of course ..... complete rework of the suspension, engine mounts (full inserts or at least front and

rear) and brake components (brake flex lines, control arms due to bushing age/weakness, panhard rods, shocks and a little drop in ride height .... not 2")
